We made it to 1.0, and with some _really_ nice goodies to boot. - -Most fun is the fact that the default printer now has *clickabble url linking* -support. A new `Diagnostic::url()` method has been added to the protocol that, -is used to figure out what URL to send folks to! This should work on most -"modern" terminals, but more thorough support checking will be done in the -future. And of course, the narrated reporter prints them out too. - -I also took the time to completely redo how messages, labels, and filenames -are handled in the system, and this is a pretty big change you might run into. -Godspeed! - -Last but not least, we got our first external contribution!

A pretty significant API change, too! �� - -#### Breaking Changes - -`SourceSpan`s have changed a bit: for one, they're based on offset/length now, -instead of start/end.

Let the person know that what they did is not appropriate and ask them to stop and/or edit their message(s) or commits. -2. That person should immediately stop the behavior and correct the issue. -3. If this doesn’t happen, or if you're uncomfortable speaking up, [contact the maintainers](#contacting-maintainers). -4. As soon as available, a maintainer will look into the issue, and take [further action (see below)](#further-enforcement), starting with a warning, then temporary block, then long-term repo or organization ban. - -When reporting, please include any relevant details, links, screenshots, context, or other information that may be used to better understand and resolve the situation. - -**The maintainer team will prioritize the well-being and comfort of the recipients of the violation over the comfort of the violator.** See [some examples below](#enforcement-examples). - -## Our Pledge - -In the interest of fostering an open and welcoming environment, we as contributors and maintainers of this project pledge to making participation in our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, technical preferences, nationality, personal appearance, race, religion, or sexual identity and orientation. - -## Our Standards - -Examples of behavior that contributes to creating a positive environment include: - - * Using welcoming and inclusive language. - * Being respectful of differing viewpoints and experiences. - * Gracefully accepting constructive feedback. - * Focusing on what is best for the community. - * Showing empathy and kindness towards other community members. - * Encouraging and raising up your peers in the project so you can all bask in hacks and glory. - -Examples of unacceptable behavior by participants include: - - * The use of sexualized language or imagery and unwelcome sexual attention or advances, including when simulated online. The only exception to sexual topics is channels/spaces specifically for topics of sexual identity. - * Casual mention of slavery or indentured servitude and/or false comparisons of one's occupation or situation to slavery. Please consider using or asking about alternate terminology when referring to such metaphors in technology. - * Making light of/making mocking comments about trigger warnings and content warnings. - * Trolling, insulting/derogatory comments, and personal or political attacks. - * Public or private harassment, deliberate intimidation, or threats. - * Publishing others' private information, such as a physical or electronic address, without explicit permission. This includes any sort of "outing" of any aspect of someone's identity without their consent. - * Publishing private screenshots or quotes of interactions in the context of this project without all quoted users' *explicit* consent. - * Publishing of private communication that doesn't have to do with reporting harassment. - * Any of the above even when [presented as "ironic" or "joking"](https://en.wikipedia.org/wiki/Hipster_racism). - * Any attempt to present "reverse-ism" versions of the above as violations. Examples of reverse-isms are "reverse racism", "reverse sexism", "heterophobia", and "cisphobia". - * Unsolicited explanations under the assumption that someone doesn't already know it. Ask before you teach! Don't assume what people's knowledge gaps are. - * [Feigning or exaggerating surprise](https://www.recurse.com/manual#no-feigned-surprise) when someone admits to not knowing something. - * "[Well-actuallies](https://www.recurse.com/manual#no-well-actuallys)" - * Other conduct which could reasonably be considered inappropriate in a professional or community setting. - -## Scope - -This Code of Conduct applies both within spaces involving this project and in other spaces involving community members. This includes the repository, its Pull Requests and Issue tracker, its Twitter community, private email communications in the context of the project, and any events where members of the project are participating, as well as adjacent communities and venues affecting the project's members. - -Depending on the violation, the maintainers may decide that violations of this code of conduct that have happened outside of the scope of the community may deem an individual unwelcome, and take appropriate action to maintain the comfort and safety of its members. - -### Other Community Standards - -As a project on GitHub, this project is additionally covered by the [GitHub Community Guidelines](https://help.github.com/articles/github-community-guidelines/). - -Enforcement of those guidelines after violations overlapping with the above are the responsibility of the entities, and enforcement may happen in any or all of the services/communities. - -## Maintainer Enforcement Process - -Once the maintainers get involved, they will follow a documented series of steps and do their best to preserve the well-being of project members. This section covers actual concrete steps. - -### Contacting Maintainers - -You may get in touch with the maintainer team through any of the following methods: - - * Through email: - * [coc@zkat.tech](mailto:coc@zkat.tech) (Kat Marchán) - - * Through Twitter: - * [@zkat__](https://twitter.com/zkat__) (Kat Marchán) - -### Further Enforcement - -If you've already followed the [initial enforcement steps](#enforcement), these are the steps maintainers will take for further enforcement, as needed: - - 1. Repeat the request to stop. - 2. If the person doubles down, they will have offending messages removed or edited by a maintainers given an official warning. The PR or Issue may be locked. - 3. If the behavior continues or is repeated later, the person will be blocked from participating for 24 hours. - 4. If the behavior continues or is repeated after the temporary block, a long-term (6-12mo) ban will be used. - -On top of this, maintainers may remove any offending messages, images, contributions, etc, as they deem necessary. - -Maintainers reserve full rights to skip any of these steps, at their discretion, if the violation is considered to be a serious and/or immediate threat to the health and well-being of members of the community. These include any threats, serious physical or verbal attacks, and other such behavior that would be completely unacceptable in any social setting that puts our members at risk. - -Members expelled from events or venues with any sort of paid attendance will not be refunded. - -### Who Watches the Watchers? - -Maintainers and other leaders who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership. These may include anything from removal from the maintainer team to a permanent ban from the community. - -Additionally, as a project hosted on GitHub, [its own Codes of Conducts may be applied against maintainers of this project](#other-community-standards), externally of this project's procedures. - -### Enforcement Examples - -#### The Best Case - -The vast majority of situations work out like this. This interaction is common, and generally positive. - -> Alex: "Yeah I used X and it was really crazy!" - -> Patt (not a maintainer): "Hey, could you not use that word? What about 'ridiculous' instead?" - -> Alex: "oh sorry, sure." -> edits old comment to say "it was really confusing!" - -#### The Maintainer Case - -Sometimes, though, you need to get maintainers involved. Maintainers will do their best to resolve conflicts, but people who were harmed by something **will take priority**. - -> Patt: "Honestly, sometimes I just really hate using $library and anyone who uses it probably sucks at their job." - -> Alex: "Whoa there, could you dial it back a bit? There's a CoC thing about attacking folks' tech use like that." - -> Patt: "I'm not attacking anyone, what's your problem?" - -> Alex: "@maintainers hey uh. Can someone look at this issue? Patt is getting a bit aggro. I tried to nudge them about it, but nope." - -> KeeperOfCommitBits: (on issue) "Hey Patt, maintainer here. Could you tone it down? This sort of attack is really not okay in this space." - -> Patt: "Leave me alone I haven't said anything bad wtf is wrong with you." - -> KeeperOfCommitBits: (deletes user's comment), "@patt I mean it. Please refer to the CoC over at (URL to this CoC) if you have questions, but you can consider this an actual warning. I'd appreciate it if you reworded your messages in this thread, since they made folks there uncomfortable. Let's try and be kind, yeah?" - -> Patt: "@keeperofbits Okay sorry. I'm just frustrated and I'm kinda burnt out and I guess I got carried away. I'll DM Alex a note apologizing and edit my messages. Sorry for the trouble." - -> KeeperOfCommitBits: "@patt Thanks for that. I hear you on the stress. Burnout sucks :/. Have a good one!" - -#### The Nope Case - -> PepeTheFrog🐸: "Hi, I am a literal actual nazi and I think white supremacists are quite fashionable." - -> Patt: "NOOOOPE. OH NOPE NOPE." - -> Alex: "JFC NO. NOPE. @keeperofbits NOPE NOPE LOOK HERE" - -> KeeperOfCommitBits: "👀 Nope. NOPE NOPE NOPE. 🔥" - -> PepeTheFrog🐸 has been banned from all organization or user repositories belonging to KeeperOfCommitBits. - -## Attribution - -This Code of Conduct was generated using [WeAllJS Code of Conduct Generator](https://npm.im/weallbehave), which is based on the [WeAllJS Code of -Conduct](https://wealljs.org/code-of-conduct), which is itself based on -[Contributor Covenant](http://contributor-covenant.org), version 1.4, available -at -[http://contributor-covenant.org/version/1/4](http://contributor-covenant.org/version/1/4), -and the LGBTQ in Technology Slack [Code of -Conduct](http://lgbtq.technology/coc.html). - diff --git a/vendor/miette/CONTRIBUTING.md b/vendor/miette/CONTRIBUTING.md deleted file mode 100644 index 87215d6..0000000 --- a/vendor/miette/CONTRIBUTING.md +++ /dev/null @@ -1,257 +0,0 @@ -# Contributing - -## How do I... <a name="toc"></a> - -* [Use This Guide](#introduction)? -* Ask or Say Something? 🤔🐛😱 - * [Request Support](#request-support) - * [Report an Error or Bug](#report-an-error-or-bug) - * [Request a Feature](#request-a-feature) -* Make Something? 🤓👩🏽💻📜🍳 - * [Project Setup](#project-setup) - * [Contribute Documentation](#contribute-documentation) - * [Contribute Code](#contribute-code) -* Manage Something ✅🙆🏼💃👔 - * [Provide Support on Issues](#provide-support-on-issues) - * [Label Issues](#label-issues) - * [Clean Up Issues and PRs](#clean-up-issues-and-prs) - * [Review Pull Requests](#review-pull-requests) - * [Merge Pull Requests](#merge-pull-requests) - * [Tag a Release](#tag-a-release) - * [Join the Project Team](#join-the-project-team) -* Add a Guide Like This One [To My Project](#attribution)? 🤖😻👻 - -## Introduction - -Thank you so much for your interest in contributing!

Yes, [even code](#contribute-code). - -If you want to go the usual route and run the project locally, though: - -* [Install Rust](https://www.rust-lang.org/learn/get-started) -* [Fork the project](https://guides.github.com/activities/forking/#fork) - -Then in your terminal: -* `cd path/to/your/clone` -* `cargo test --features fancy` - -And you should be ready to go! - -**Note:** If you don't include the "fancy" feature, one of the doc-tests will fail. - -## Contribute Documentation - -Documentation is a super important, critical part of this project. Docs are how we keep track of what we're doing, how, and why. It's how we stay on the same page about our policies. And it's how we tell others everything they need in order to be able to use this project -- or contribute to it. So thank you in advance. - -Documentation contributions of any size are welcome! Feel free to file a PR even if you're just rewording a sentence to be more clear, or fixing a spelling mistake! - -To contribute documentation: - -* [Set up the project](#project-setup). -* Edit or add any relevant documentation. -* Make sure your changes are formatted correctly and consistently with the rest of the documentation. -* Re-read what you wrote, and run a spellchecker on it to make sure you didn't miss anything. -* Write clear, concise commit message(s) using [conventional-changelog format](https://github.com/conventional-changelog/conventional-changelog-angular/blob/master/convention.md). Documentation commits should use `docs(<component>): <message>`. -* Go to https://github.com/zkat/miette/pulls and open a new pull request with your changes. -* If your PR is connected to an open issue, add a line in your PR's description that says `Fixes: #123`, where `#123` is the number of the issue you're fixing. - -Once you've filed the PR: - -* One or more maintainers will use GitHub's review feature to review your PR. -* If the maintainer asks for any changes, edit your changes, push, and ask for another review. -* If the maintainer decides to pass on your PR, they will thank you for the contribution and explain why they won't be accepting the changes. That's ok! We still really appreciate you taking the time to do it, and we don't take that lightly. 💚 -* If your PR gets accepted, it will be marked as such, and merged into the `latest` branch soon after. Your contribution will be distributed to the masses next time the maintainers [tag a release](#tag-a-release) - -## Contribute Code - -We like code commits a lot! They're super handy, and they keep the project going and doing the work it needs to do to be useful to others. - -Code contributions of just about any size are acceptable! - -The main difference between code contributions and documentation contributions is that contributing code requires inclusion of relevant tests for the code being added or changed. Contributions without accompanying tests will be held off until a test is added, unless the maintainers consider the specific tests to be either impossible, or way too much of a burden for such a contribution. - -To contribute code: - -* [Set up the project](#project-setup). -* Make any necessary changes to the source code. -* Include any [additional documentation](#contribute-documentation) the changes might need. -* Write tests that verify that your contribution works as expected. -* Write clear, concise commit message(s) using [conventional-changelog format](https://github.com/conventional-changelog/conventional-changelog-angular/blob/master/convention.md). -* Dependency updates, additions, or removals must be in individual commits, and the message must use the format: `<prefix>(deps): PKG@VERSION`, where `<prefix>` is any of the usual `conventional-changelog` prefixes, at your discretion. -* Go to https://github.com/zkat/miette/pulls and open a new pull request with your changes. -* If your PR is connected to an open issue, add a line in your PR's description that says `Fixes: #123`, where `#123` is the number of the issue you're fixing. - -Once you've filed the PR: - -* Barring special circumstances, maintainers will not review PRs until all checks pass (Travis, AppVeyor, etc). -* One or more maintainers will use GitHub's review feature to review your PR. -* If the maintainer asks for any changes, edit your changes, push, and ask for another review. Additional tags (such as `needs-tests`) will be added depending on the review. -* If the maintainer decides to pass on your PR, they will thank you for the contribution and explain why they won't be accepting the changes. That's ok! We still really appreciate you taking the time to do it, and we don't take that lightly. 💚 -* If your PR gets accepted, it will be marked as such, and merged into the `latest` branch soon after. Your contribution will be distributed to the masses next time the maintainers [tag a release](#tag-a-release) - -## Provide Support on Issues - -[Needs Collaborator](#join-the-project-team): none - -Helping out other users with their questions is a really awesome way of contributing to any community. It's not uncommon for most of the issues on an open source projects being support-related questions by users trying to understand something they ran into, or find their way around a known bug. - -Sometimes, the `support` label will be added to things that turn out to actually be other things, like bugs or feature requests. In that case, suss out the details with the person who filed the original issue, add a comment explaining what the bug is, and change the label from `support` to `bug` or `feature`. If you can't do this yourself, @mention a maintainer so they can do it. - -In order to help other folks out with their questions: - -* Go to the issue tracker and [filter open issues by the `support` label](https://github.com/zkat/miette/issues?q=is%3Aopen+is%3Aissue+label%3Asupport). -* Read through the list until you find something that you're familiar enough with to give an answer to. -* Respond to the issue with whatever details are needed to clarify the question, or get more details about what's going on. -* Once the discussion wraps up and things are clarified, either close the issue, or ask the original issue filer (or a maintainer) to close it for you. - -Some notes on picking up support issues: - -* Avoid responding to issues you don't know you can answer accurately. -* As much as possible, try to refer to past issues with accepted answers. Link to them from your replies with the `#123` format. -* Be kind and patient with users -- often, folks who have run into confusing things might be upset or impatient. This is ok. Try to understand where they're coming from, and if you're too uncomfortable with the tone, feel free to stay away or withdraw from the issue. (note: if the user is outright hostile or is violating the CoC, [refer to the Code of Conduct](CODE_OF_CONDUCT.md) to resolve the conflict). - -## Label Issues - -[Needs Collaborator](#join-the-project-team): Issue Tracker - -One of the most important tasks in handling issues is labeling them usefully and accurately. All other tasks involving issues ultimately rely on the issue being classified in such a way that relevant parties looking to do their own tasks can find them quickly and easily. - -In order to label issues, [open up the list of unlabeled issues](https://github.com/zkat/miette/issues?q=is%3Aopen+is%3Aissue+no%3Alabel) and, **from newest to oldest**, read through each one and apply issue labels according to the table below. If you're unsure about what label to apply, skip the issue and try the next one: don't feel obligated to label each and every issue yourself! - -Label | Apply When | Notes ---- | --- | --- -`bug` | Cases where the code (or documentation) is behaving in a way it wasn't intended to. | If something is happening that surprises the *user* but does not go against the way the code is designed, it should use the `enhancement` label. -`critical` | Added to `bug` issues if the problem described makes the code completely unusable in a common situation. | -`documentation` | Added to issues or pull requests that affect any of the documentation for the project. | Can be combined with other labels, such as `bug` or `enhancement`. -`duplicate` | Added to issues or PRs that refer to the exact same issue as another one that's been previously labeled. | Duplicate issues should be marked and closed right away, with a message referencing the issue it's a duplicate of (with `#123`) -`enhancement` | Added to [feature requests](#request-a-feature), PRs, or documentation issues that are purely additive: the code or docs currently work as expected, but a change is being requested or suggested. | -`help wanted` | Applied by [Committers](#join-the-project-team) to issues and PRs that they would like to get outside help for. Generally, this means it's lower priority for the maintainer team to itself implement, but that the community is encouraged to pick up if they so desire | Never applied on first-pass labeling. -`in-progress` | Applied by [Committers](#join-the-project-team) to PRs that are pending some work before they're ready for review. | The original PR submitter should @mention the team member that applied the label once the PR is complete. -`performance` | This issue or PR is directly related to improving performance. | -`refactor` | Added to issues or PRs that deal with cleaning up or modifying the project for the betterment of it. | -`starter` | Applied by [Committers](#join-the-project-team) to issues that they consider good introductions to the project for people who have not contributed before. These are not necessarily "easy", but rather focused around how much context is necessary in order to understand what needs to be done for this project in particular. | Existing project members are expected to stay away from these unless they increase in priority. -`support` | This issue is either asking a question about how to use the project, clarifying the reason for unexpected behavior, or possibly reporting a `bug` but does not have enough detail yet to determine whether it would count as such. | The label should be switched to `bug` if reliable reproduction steps are provided. Issues primarily with unintended configurations of a user's environment are not considered bugs, even if they cause crashes. -`tests` | This issue or PR either requests or adds primarily tests to the project. | If a PR is pending tests, that will be handled through the [PR review process](#review-pull-requests) -`wontfix` | Labelers may apply this label to issues that clearly have nothing at all to do with the project or are otherwise entirely outside of its scope/sphere of influence. [Committers](#join-the-project-team) may apply this label and close an issue or PR if they decide to pass on an otherwise relevant issue. | The issue or PR should be closed as soon as the label is applied, and a clear explanation provided of why the label was used. Contributors are free to contest the labeling, but the decision ultimately falls on committers as to whether to accept something or not. - -## Clean Up Issues and PRs - -[Needs Collaborator](#join-the-project-team): Issue Tracker - -Issues and PRs can go stale after a while. Maybe they're abandoned. Maybe the team will just plain not have time to address them any time soon. - -In these cases, they should be closed until they're brought up again or the interaction starts over. - -To clean up issues and PRs: - -* Search the issue tracker for issues or PRs, and add the term `updated:<=YYYY-MM-DD`, where the date is 30 days before today. -* Go through each issue *from oldest to newest*, and close them if **all of the following are true**: - * not opened by a maintainer - * not marked as `critical` - * not marked as `starter` or `help wanted` (these might stick around for a while, in general, as they're intended to be available) - * no explicit messages in the comments asking for it to be left open - * does not belong to a milestone -* Leave a message when closing saying "Cleaning up stale issue. Please reopen or ping us if and when you're ready to resume this. See https://github.com/zkat/miette/blob/latest/CONTRIBUTING.md#clean-up-issues-and-prs for more details." - -## Review Pull Requests - -[Needs Collaborator](#join-the-project-team): Issue Tracker - -While anyone can comment on a PR, add feedback, etc, PRs are only *approved* by team members with Issue Tracker or higher permissions. - -PR reviews use [GitHub's own review feature](https://help.github.com/articles/about-pull-request-reviews/), which manages comments, approval, and review iteration. - -Some notes: - -* You may ask for minor changes ("nitpicks"), but consider whether they are really blockers to merging: try to err on the side of "approve, with comments". -* *ALL PULL REQUESTS* should be covered by a test: either by a previously-failing test, an existing test that covers the entire functionality of the submitted code, or new tests to verify any new/changed behavior. All tests must also pass and follow established conventions. Test coverage should not drop, unless the specific case is considered reasonable by maintainers. -* Please make sure you're familiar with the code or documentation being updated, unless it's a minor change (spellchecking, minor formatting, etc). You may @mention another project member who you think is better suited for the review, but still provide a non-approving review of your own. -* Be extra kind: people who submit code/doc contributions are putting themselves in a pretty vulnerable position, and have put time and care into what they've done (even if that's not obvious to you!) -- always respond with respect, be understanding, but don't feel like you need to sacrifice your standards for their sake, either. Just don't be a jerk about it? - -## Merge Pull Requests - -[Needs Collaborator](#join-the-project-team): Committer - -TBD - need to hash out a bit more of this process. - -## Tag A Release - -[Needs Collaborator](#join-the-project-team): Committer - -TBD - need to hash out a bit more of this process. The most important bit here is probably that all tests must pass, and tags must use [semver](https://semver.org). - -## Join the Project Team - -### Ways to Join - -There are many ways to contribute! Most of them don't require any official status unless otherwise noted. That said, there's a couple of positions that grant special repository abilities, and this section describes how they're granted and what they do. - -All of the below positions are granted based on the project team's needs, as well as their consensus opinion about whether they would like to work with the person and think that they would fit well into that position. The process is relatively informal, and it's likely that people who express interest in participating can just be granted the permissions they'd like. - -You can spot a collaborator on the repo by looking for the `[Collaborator]` or `[Owner]` tags next to their names. - -Permission | Description ---- | --- -Issue Tracker | Granted to contributors who express a strong interest in spending time on the project's issue tracker. These tasks are mainly [labeling issues](#label-issues), [cleaning up old ones](#clean-up-issues-and-prs), and [reviewing pull requests](#review-pull-requests), as well as all the usual things non-team-member contributors can do. Issue handlers should not merge pull requests, tag releases, or directly commit code themselves: that should still be done through the usual pull request process. Becoming an Issue Handler means the project team trusts you to understand enough of the team's process and context to implement it on the issue tracker. -Committer | Granted to contributors who want to handle the actual pull request merges, tagging new versions, etc. Committers should have a good level of familiarity with the codebase, and enough context to understand the implications of various changes, as well as a good sense of the will and expectations of the project team. -Admin/Owner | Granted to people ultimately responsible for the project, its community, etc. - -## Attribution - -This guide was generated using the WeAllJS `CONTRIBUTING.md` generator.

It's a best -practice to wrap any "external" error types in your error `enum` instead of -using something like [`Report`] in a library. - -#### ... in application code - -Application code tends to work a little differently than libraries. You -don't always need or care to define dedicated error wrappers for errors -coming from external libraries and tools. - -For this situation, `miette` includes two tools: [`Report`] and -[`IntoDiagnostic`]. They work in tandem to make it easy to convert regular -`std::error::Error`s into [`Diagnostic`]s. Additionally, there's a -[`Result`] type alias that you can use to be more terse. - -When dealing with non-`Diagnostic` types, you'll want to -`.into_diagnostic()` them: - -```rust -// my_app/lib/my_internal_file.rs -use miette::{IntoDiagnostic, Result}; -use semver::Version; - -pub fn some_tool() -> Result<Version> { - Ok("1.2.x".parse().into_diagnostic()?) -} -``` - -`miette` also includes an `anyhow`/`eyre`-style `Context`/`WrapErr` traits -that you can import to add ad-hoc context messages to your `Diagnostic`s, as -well, though you'll still need to use `.into_diagnostic()` to make use of -it: - -```rust -// my_app/lib/my_internal_file.rs -use miette::{IntoDiagnostic, Result, WrapErr}; -use semver::Version; - -pub fn some_tool() -> Result<Version> { - Ok("1.2.x" - .parse() - .into_diagnostic() - .wrap_err("Parsing this tool's semver version failed.")?) -} -``` - -To construct your own simple adhoc error use the [miette!] macro: -```rust -// my_app/lib/my_internal_file.rs -use miette::{miette, IntoDiagnostic, Result, WrapErr}; -use semver::Version; - -pub fn some_tool() -> Result<Version> { - let version = "1.2.x"; - Ok(version - .parse() - .map_err(|_| miette!("Invalid version {}", version))?) -} -``` -There are also similar [bail!] and [ensure!] macros. - -#### ... in `main()` - -`main()` is just like any other part of your application-internal code.

This URL will -be displayed as an actual link in supported terminals, like so: - -<img -src="https://raw.githubusercontent.com/zkat/miette/main/images/code_linking.png" -alt=" Example showing the graphical report printer for miette -pretty-printing an error code. The code is underlined and followed by text -saying to 'click here'. A hover tooltip shows a full-fledged URL that can be -Ctrl+Clicked to open in a browser. -\ -This feature is also available in the narratable printer. It will add a line -after printing the error code showing a plain URL that you can visit. -"> - -To use this, you can add a `url()` sub-param to your `#[diagnostic]` -attribute: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Error, Diagnostic, Debug)] -#[error("kaboom")] -#[diagnostic( - code(my_app::my_error), - // You can do formatting! - url("https://my_website.com/error_codes#{}", self.code().unwrap()) -)] -struct MyErr; -``` - -Additionally, if you're developing a library and your error type is exported -from your crate's top level, you can use a special `url(docsrs)` option -instead of manually constructing the URL. This will automatically create a -link to this diagnostic on `docs.rs`, so folks can just go straight to your -(very high quality and detailed!) documentation on this diagnostic: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Error, Diagnostic, Debug)] -#[diagnostic( - code(my_app::my_error), - // Will link users to https://docs.rs/my_crate/0.0.0/my_crate/struct.MyErr.html - url(docsrs) -)] -#[error("kaboom")] -struct MyErr; -``` - -#### ... snippets - -Along with its general error handling and reporting features, `miette` also -includes facilities for adding error spans/annotations/labels to your -output. This can be very useful when an error is syntax-related, but you can -even use it to print out sections of your own source code! - -To achieve this, `miette` defines its own lightweight [`SourceSpan`] type. -This is a basic byte-offset and length into an associated [`SourceCode`] -and, along with the latter, gives `miette` all the information it needs to -pretty-print some snippets! You can also use your own `Into<SourceSpan>` -types as label spans. - -The easiest way to define errors like this is to use the -`derive(Diagnostic)` macro: - -```rust -use miette::{Diagnostic, SourceSpan}; -use thiserror::Error; - -#[derive(Diagnostic, Debug, Error)] -#[error("oops")] -#[diagnostic(code(my_lib::random_error))] -pub struct MyErrorType { - // The `Source` that miette will use. - #[source_code] - src: String, - - // This will underline/mark the specific code inside the larger - // snippet context. - #[label = "This is the highlight"] - err_span: SourceSpan, - - // You can add as many labels as you want. - // They'll be rendered sequentially. - #[label("This is bad")] - snip2: (usize, usize), // `(usize, usize)` is `Into<SourceSpan>`! - - // Snippets can be optional, by using Option: - #[label("some text")] - snip3: Option<SourceSpan>, - - // with or without label text - #[label] - snip4: Option<SourceSpan>, -} -``` - -##### ... help text -`miette` provides two facilities for supplying help text for your errors: - -The first is the `#[help()]` format attribute that applies to structs or -enum variants: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Debug, Diagnostic, Error)] -#[error("welp")] -#[diagnostic(help("try doing this instead"))] -struct Foo; -``` - -The other is by programmatically supplying the help text as a field to -your diagnostic: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Debug, Diagnostic, Error)] -#[error("welp")] -#[diagnostic()] -struct Foo { - #[help] - advice: Option<String>, // Can also just be `String` -} - -let err = Foo { - advice: Some("try doing this instead".to_string()), -}; -``` - -#### ... multiple related errors - -`miette` supports collecting multiple errors into a single diagnostic, and -printing them all together nicely. - -To do so, use the `#[related]` tag on any `IntoIter` field in your -`Diagnostic` type: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Debug, Error, Diagnostic)] -#[error("oops")] -struct MyError { - #[related] - others: Vec<MyError>, -} -``` - -#### ... delayed source code - -Sometimes it makes sense to add source code to the error message later. -One option is to use [`with_source_code()`](Report::with_source_code) -method for that: - -```rust -use miette::{Diagnostic, SourceSpan}; -use thiserror::Error; - -#[derive(Diagnostic, Debug, Error)] -#[error("oops")] -#[diagnostic()] -pub struct MyErrorType { - // Note: label but no source code - #[label] - err_span: SourceSpan, -} - -fn do_something() -> miette::Result<()> { - // This function emits actual error with label - return Err(MyErrorType { - err_span: (7..11).into(), - })?; -} - -fn main() -> miette::Result<()> { - do_something().map_err(|error| { - // And this code provides the source code for inner error - error.with_source_code(String::from("source code")) - }) -} -``` - -Also source code can be provided by a wrapper type. This is especially -useful in combination with `related`, when multiple errors should be -emitted at the same time: - -```rust -use miette::{Diagnostic, Report, SourceSpan}; -use thiserror::Error; - -#[derive(Diagnostic, Debug, Error)] -#[error("oops")] -#[diagnostic()] -pub struct InnerError { - // Note: label but no source code - #[label] - err_span: SourceSpan, -} - -#[derive(Diagnostic, Debug, Error)] -#[error("oops: multiple errors")] -#[diagnostic()] -pub struct MultiError { - // Note source code by no labels - #[source_code] - source_code: String, - // The source code above is used for these errors - #[related] - related: Vec<InnerError>, -} - -fn do_something() -> Result<(), Vec<InnerError>> { - Err(vec![ - InnerError { - err_span: (0..6).into(), - }, - InnerError { - err_span: (7..11).into(), - }, - ]) -} - -fn main() -> miette::Result<()> { - do_something().map_err(|err_list| MultiError { - source_code: "source code".into(), - related: err_list, - })?; - Ok(()) -} -``` - -#### ... Diagnostic-based error sources. - -When one uses the `#[source]` attribute on a field, that usually comes -from `thiserror`, and implements a method for -[`std::error::Error::source`]. This works in many cases, but it's lossy: -if the source of the diagnostic is a diagnostic itself, the source will -simply be treated as an `std::error::Error`. - -While this has no effect on the existing _reporters_, since they don't use -that information right now, APIs who might want this information will have -no access to it. - -If it's important for you for this information to be available to users, -you can use `#[diagnostic_source]` alongside `#[source]`. Not that you -will likely want to use _both_: - -```rust -use miette::Diagnostic; -use thiserror::Error; - -#[derive(Debug, Diagnostic, Error)] -#[error("MyError")] -struct MyError { - #[source] - #[diagnostic_source] - the_cause: OtherError, -} - -#[derive(Debug, Diagnostic, Error)] -#[error("OtherError")] -struct OtherError; -``` - -#### ... handler options - -[`MietteHandler`] is the default handler, and is very customizable. In -most cases, you can simply use [`MietteHandlerOpts`] to tweak its behavior -instead of falling back to your own custom handler. - -Usage is like so: - -```rust -miette::set_hook(Box::new(|_| { - Box::new( - miette::MietteHandlerOpts::new() - .terminal_links(true) - .unicode(false) - .context_lines(3) - .tab_width(4) - .build(), - ) -})) - -``` - -See the docs for [`MietteHandlerOpts`] for more details on what you can -customize! - -#### ... dynamic diagnostics - -If you... -- ...don't know all the possible errors upfront -- ...need to serialize/deserialize errors -then you may want to use [`miette!`], [`diagnostic!`] macros or -[`MietteDiagnostic`] directly to create diagnostic on the fly. - -```rust - -let source = "2 + 2 * 2 = 8".to_string(); -let report = miette!( - labels = vec[ - LabeledSpan::at(12..13, "this should be 6"), - ], - help = "'*' has greater precedence than '+'", - "Wrong answer" -).with_source_code(source); -println!("{:?}", report) -``` - -### Acknowledgements - -`miette` was not developed in a void.

For more details, see https://docs.rs/nu-parser/0.1.0/nu-parser/enum.ParseError.html#variant.UnsupportedOperation"> -//! -//! ## Using -//! -//! ### ... in libraries -//! -//! `miette` is _fully compatible_ with library usage. Consumers who don't know -//! about, or don't want, `miette` features can safely use its error types as -//! regular [`std::error::Error`]. -//! -//! We highly recommend using something like [`thiserror`](https://docs.rs/thiserror) -//! to define unique error types and error wrappers for your library. -//! -//! While `miette` integrates smoothly with `thiserror`, it is _not required_. -//! If you don't want to use the [`Diagnostic`] derive macro, you can implement -//! the trait directly, just like with `std::error::Error`. -//! -//! ```rust -//! // lib/error.rs -//! use miette::{Diagnostic, SourceSpan}; -//! use thiserror::Error; -//! -//! #[derive(Error, Diagnostic, Debug)] -//! pub enum MyLibError { -//! #[error(transparent)] -//! #[diagnostic(code(my_lib::io_error))] -//! IoError(#[from] std::io::Error), -//! -//! #[error("Oops it blew up")] -//! #[diagnostic(code(my_lib::bad_code))] -//! BadThingHappened, -//! -//! #[error(transparent)] -//! // Use `#[diagnostic(transparent)]` to wrap another [`Diagnostic`]. You won't see labels otherwise -//! #[diagnostic(transparent)] -//! AnotherError(#[from] AnotherError), -//! } -//! -//! #[derive(Error, Diagnostic, Debug)] -//! #[error("another error")] -//! pub struct AnotherError { -//! #[label("here")] -//! pub at: SourceSpan -//! } -//! ``` -//! -//! Then, return this error type from all your fallible public APIs. It's a best -//! practice to wrap any "external" error types in your error `enum` instead of -//! using something like [`Report`] in a library. -//! -//! ### ... in application code -//! -//! Application code tends to work a little differently than libraries. You -//! don't always need or care to define dedicated error wrappers for errors -//! coming from external libraries and tools. -//! -//! For this situation, `miette` includes two tools: [`Report`] and -//! [`IntoDiagnostic`]. They work in tandem to make it easy to convert regular -//! `std::error::Error`s into [`Diagnostic`]s. Additionally, there's a -//! [`Result`] type alias that you can use to be more terse. -//! -//! When dealing with non-`Diagnostic` types, you'll want to -//! `.into_diagnostic()` them: -//! -//! ```rust -//! // my_app/lib/my_internal_file.rs -//! use miette::{IntoDiagnostic, Result}; -//! use semver::Version; -//! -//! pub fn some_tool() -> Result<Version> { -//! Ok("1.2.x".parse().into_diagnostic()?) -//! } -//! ``` -//! -//! `miette` also includes an `anyhow`/`eyre`-style `Context`/`WrapErr` traits -//! that you can import to add ad-hoc context messages to your `Diagnostic`s, as -//! well, though you'll still need to use `.into_diagnostic()` to make use of -//! it: -//! -//! ```rust -//! // my_app/lib/my_internal_file.rs -//! use miette::{IntoDiagnostic, Result, WrapErr}; -//! use semver::Version; -//! -//! pub fn some_tool() -> Result<Version> { -//! Ok("1.2.x" -//! .parse() -//! .into_diagnostic() -//! .wrap_err("Parsing this tool's semver version failed.")?) -//! } -//! ``` -//! -//! To construct your own simple adhoc error use the [miette!] macro: -//! ```rust -//! // my_app/lib/my_internal_file.rs -//! use miette::{miette, IntoDiagnostic, Result, WrapErr}; -//! use semver::Version; -//! -//! pub fn some_tool() -> Result<Version> { -//! let version = "1.2.x"; -//! Ok(version -//! .parse() -//! .map_err(|_| miette!("Invalid version {}", version))?) -//! } -//! ``` -//! There are also similar [bail!] and [ensure!] macros. -//! -//! ### ... in `main()` -//! -//! `main()` is just like any other part of your application-internal code. Use -//! `Result` as your return value, and it will pretty-print your diagnostics -//! automatically. -//! -//! > **NOTE:** You must enable the `"fancy"` crate feature to get fancy report -//! output like in the screenshots here.** You should only do this in your -//! toplevel crate, as the fancy feature pulls in a number of dependencies that -//! libraries and such might not want. -//! -//! ```rust -//! use miette::{IntoDiagnostic, Result}; -//! use semver::Version; -//! -//! fn pretend_this_is_main() -> Result<()> { -//! let version: Version = "1.2.x".parse().into_diagnostic()?; -//! println!("{}", version); -//! Ok(()) -//! } -//! ``` -//! -//! Please note: in order to get fancy diagnostic rendering with all the pretty -//! colors and arrows, you should install `miette` with the `fancy` feature -//! enabled: -//! -//! ```toml -//! miette = { version = "X.Y.Z", features = ["fancy"] } -//! ``` -//! -//! ### ... diagnostic code URLs -//! -//! `miette` supports providing a URL for individual diagnostics. This URL will -//! be displayed as an actual link in supported terminals, like so: -//! -//! <img -//! src="https://raw.githubusercontent.com/zkat/miette/main/images/code_linking.png" -//! alt=" Example showing the graphical report printer for miette -//! pretty-printing an error code. The code is underlined and followed by text -//! saying to 'click here'. A hover tooltip shows a full-fledged URL that can be -//! Ctrl+Clicked to open in a browser. -//! \ -//! This feature is also available in the narratable printer. It will add a line -//! after printing the error code showing a plain URL that you can visit. -//! "> -//! -//! To use this, you can add a `url()` sub-param to your `#[diagnostic]` -//! attribute: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Error, Diagnostic, Debug)] -//! #[error("kaboom")] -//! #[diagnostic( -//! code(my_app::my_error), -//! // You can do formatting! -//! url("https://my_website.com/error_codes#{}", self.code().unwrap()) -//! )] -//! struct MyErr; -//! ``` -//! -//! Additionally, if you're developing a library and your error type is exported -//! from your crate's top level, you can use a special `url(docsrs)` option -//! instead of manually constructing the URL. This will automatically create a -//! link to this diagnostic on `docs.rs`, so folks can just go straight to your -//! (very high quality and detailed!) documentation on this diagnostic: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Error, Diagnostic, Debug)] -//! #[diagnostic( -//! code(my_app::my_error), -//! // Will link users to https://docs.rs/my_crate/0.0.0/my_crate/struct.MyErr.html -//! url(docsrs) -//! )] -//! #[error("kaboom")] -//! struct MyErr; -//! ``` -//! -//! ### ... snippets -//! -//! Along with its general error handling and reporting features, `miette` also -//! includes facilities for adding error spans/annotations/labels to your -//! output. This can be very useful when an error is syntax-related, but you can -//! even use it to print out sections of your own source code! -//! -//! To achieve this, `miette` defines its own lightweight [`SourceSpan`] type. -//! This is a basic byte-offset and length into an associated [`SourceCode`] -//! and, along with the latter, gives `miette` all the information it needs to -//! pretty-print some snippets! You can also use your own `Into<SourceSpan>` -//! types as label spans. -//! -//! The easiest way to define errors like this is to use the -//! `derive(Diagnostic)` macro: -//! -//! ```rust -//! use miette::{Diagnostic, SourceSpan}; -//! use thiserror::Error; -//! -//! #[derive(Diagnostic, Debug, Error)] -//! #[error("oops")] -//! #[diagnostic(code(my_lib::random_error))] -//! pub struct MyErrorType { -//! // The `Source` that miette will use. -//! #[source_code] -//! src: String, -//! -//! // This will underline/mark the specific code inside the larger -//! // snippet context. -//! #[label = "This is the highlight"] -//! err_span: SourceSpan, -//! -//! // You can add as many labels as you want. -//! // They'll be rendered sequentially. -//! #[label("This is bad")] -//! snip2: (usize, usize), // `(usize, usize)` is `Into<SourceSpan>`! -//! -//! // Snippets can be optional, by using Option: -//! #[label("some text")] -//! snip3: Option<SourceSpan>, -//! -//! // with or without label text -//! #[label] -//! snip4: Option<SourceSpan>, -//! } -//! ``` -//! -//! #### ... help text -//! `miette` provides two facilities for supplying help text for your errors: -//! -//! The first is the `#[help()]` format attribute that applies to structs or -//! enum variants: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Debug, Diagnostic, Error)] -//! #[error("welp")] -//! #[diagnostic(help("try doing this instead"))] -//! struct Foo; -//! ``` -//! -//! The other is by programmatically supplying the help text as a field to -//! your diagnostic: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Debug, Diagnostic, Error)] -//! #[error("welp")] -//! #[diagnostic()] -//! struct Foo { -//! #[help] -//! advice: Option<String>, // Can also just be `String` -//! } -//! -//! let err = Foo { -//! advice: Some("try doing this instead".to_string()), -//! }; -//! ``` -//! -//! ### ... multiple related errors -//! -//! `miette` supports collecting multiple errors into a single diagnostic, and -//! printing them all together nicely. -//! -//! To do so, use the `#[related]` tag on any `IntoIter` field in your -//! `Diagnostic` type: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Debug, Error, Diagnostic)] -//! #[error("oops")] -//! struct MyError { -//! #[related] -//! others: Vec<MyError>, -//! } -//! ``` -//! -//! ### ... delayed source code -//! -//! Sometimes it makes sense to add source code to the error message later. -//! One option is to use [`with_source_code()`](Report::with_source_code) -//! method for that: -//! -//! ```rust,no_run -//! use miette::{Diagnostic, SourceSpan}; -//! use thiserror::Error; -//! -//! #[derive(Diagnostic, Debug, Error)] -//! #[error("oops")] -//! #[diagnostic()] -//! pub struct MyErrorType { -//! // Note: label but no source code -//! #[label] -//! err_span: SourceSpan, -//! } -//! -//! fn do_something() -> miette::Result<()> { -//! // This function emits actual error with label -//! return Err(MyErrorType { -//! err_span: (7..11).into(), -//! })?; -//! } -//! -//! fn main() -> miette::Result<()> { -//! do_something().map_err(|error| { -//! // And this code provides the source code for inner error -//! error.with_source_code(String::from("source code")) -//! }) -//! } -//! ``` -//! -//! Also source code can be provided by a wrapper type. This is especially -//! useful in combination with `related`, when multiple errors should be -//! emitted at the same time: -//! -//! ```rust,no_run -//! use miette::{Diagnostic, Report, SourceSpan}; -//! use thiserror::Error; -//! -//! #[derive(Diagnostic, Debug, Error)] -//! #[error("oops")] -//! #[diagnostic()] -//! pub struct InnerError { -//! // Note: label but no source code -//! #[label] -//! err_span: SourceSpan, -//! } -//! -//! #[derive(Diagnostic, Debug, Error)] -//! #[error("oops: multiple errors")] -//! #[diagnostic()] -//! pub struct MultiError { -//! // Note source code by no labels -//! #[source_code] -//! source_code: String, -//! // The source code above is used for these errors -//! #[related] -//! related: Vec<InnerError>, -//! } -//! -//! fn do_something() -> Result<(), Vec<InnerError>> { -//! Err(vec![ -//! InnerError { -//! err_span: (0..6).into(), -//! }, -//! InnerError { -//! err_span: (7..11).into(), -//! }, -//! ]) -//! } -//! -//! fn main() -> miette::Result<()> { -//! do_something().map_err(|err_list| MultiError { -//! source_code: "source code".into(), -//! related: err_list, -//! })?; -//! Ok(()) -//! } -//! ``` -//! -//! ### ... Diagnostic-based error sources. -//! -//! When one uses the `#[source]` attribute on a field, that usually comes -//! from `thiserror`, and implements a method for -//! [`std::error::Error::source`]. This works in many cases, but it's lossy: -//! if the source of the diagnostic is a diagnostic itself, the source will -//! simply be treated as an `std::error::Error`. -//! -//! While this has no effect on the existing _reporters_, since they don't use -//! that information right now, APIs who might want this information will have -//! no access to it. -//! -//! If it's important for you for this information to be available to users, -//! you can use `#[diagnostic_source]` alongside `#[source]`. Not that you -//! will likely want to use _both_: -//! -//! ```rust -//! use miette::Diagnostic; -//! use thiserror::Error; -//! -//! #[derive(Debug, Diagnostic, Error)] -//! #[error("MyError")] -//! struct MyError { -//! #[source] -//! #[diagnostic_source] -//! the_cause: OtherError, -//! } -//! -//! #[derive(Debug, Diagnostic, Error)] -//! #[error("OtherError")] -//! struct OtherError; -//! ``` -//! -//! ### ... handler options -//! -//! [`MietteHandler`] is the default handler, and is very customizable. In -//! most cases, you can simply use [`MietteHandlerOpts`] to tweak its behavior -//! instead of falling back to your own custom handler. -//! -//! Usage is like so: -//! -//! ```rust,ignore -//! miette::set_hook(Box::new(|_| { -//! Box::new( -//! miette::MietteHandlerOpts::new() -//! .terminal_links(true) -//! .unicode(false) -//! .context_lines(3) -//! .tab_width(4) -//! .build(), -//! ) -//! })) -//! -//! # .unwrap() -//! ``` -//! -//! See the docs for [`MietteHandlerOpts`] for more details on what you can -//! customize! -//! -//! ### ... dynamic diagnostics -//! -//! If you... -//! - ...don't know all the possible errors upfront -//! - ...need to serialize/deserialize errors -//! then you may want to use [`miette!`], [`diagnostic!`] macros or -//! [`MietteDiagnostic`] directly to create diagnostic on the fly. -//! -//! ```rust,ignore -//! # use miette::{miette, LabeledSpan, Report}; -//! -//! let source = "2 + 2 * 2 = 8".to_string(); -//! let report = miette!( -//! labels = vec[ -//! LabeledSpan::at(12..13, "this should be 6"), -//! ], -//! help = "'*' has greater precedence than '+'", -//! "Wrong answer" -//! ).with_source_code(source); -//! println!("{:?}", report) -//! ``` -//! -//! ## Acknowledgements -//! -//! `miette` was not developed in a void. It owes enormous credit to various -//! other projects and their authors: -//! -//! - [`anyhow`](http://crates.io/crates/anyhow) and [`color-eyre`](https://crates.io/crates/color-eyre): -//! these two enormously influential error handling libraries have pushed -//! forward the experience of application-level error handling and error -//! reporting. `miette`'s `Report` type is an attempt at a very very rough -//! version of their `Report` types. -//! - [`thiserror`](https://crates.io/crates/thiserror) for setting the standard -//! for library-level error definitions, and for being the inspiration behind -//! `miette`'s derive macro. -//! - `rustc` and [@estebank](https://github.com/estebank) for their -//! state-of-the-art work in compiler diagnostics. -//! - [`ariadne`](https://crates.io/crates/ariadne) for pushing forward how -//! _pretty_ these diagnostics can really look! -//! -//! ## License -//! -//! `miette` is released to the Rust community under the [Apache license -//! 2.0](./LICENSE). -//! -//!
