Set maximum Rust version to 1.31.0 By setting the minimum Rust version and enforcing it with CI, Alacritty should hopefully make it possible for maintainers to package the application even on distributions which are not rolling release. The 1.31.0 target has been chosen here because it's the first version of the Rust 2018 release. Bumping this version in the future should be considered to be a breaking change and should only be done with caution and in consideration of the supported Rust versions of the major distributions available. This fixes #2277.

## Feature Requests
Feature requests should be reported in the [Alacritty issue tracker](https://github.com/jwilm/alacritty/issues). To reduce the number of duplicates, please make sure to check the existing [enhancement](https://github.com/jwilm/alacritty/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3Aenhancement) and [missing feature](https://github.com/jwilm/alacritty/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3A%22B+-+missing+feature%22) issues.
## Bug Reports
Bug reports should be reported in the [Alacritty issue tracker](https://github.com/jwilm/alacritty/issues).
If a bug was not present in a previous version of Alacritty, providing the exact commit which introduced the regression helps out a lot.
## Patches / Pull Requests
All patches have to be sent on Github as [pull requests](https://github.com/jwilm/alacritty/pulls).
If you are looking for a place to start contributing to Alacritty, take a look at the [help wanted](https://github.com/jwilm/alacritty/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22) and [easy](https://github.com/jwilm/alacritty/issues?q=is%3Aopen+is%3Aissue+label%3A%22D+-+easy%22) issues.
Bump minimum Rust version to 1.36.0
2019-09-09 21:40:48 +00:00
Please note that the minimum supported version of Alacritty is Rust 1.36.0. All patches are expected to work with the minimum supported version.
Set maximum Rust version to 1.31.0 By setting the minimum Rust version and enforcing it with CI, Alacritty should hopefully make it possible for maintainers to package the application even on distributions which are not rolling release. The 1.31.0 target has been chosen here because it's the first version of the Rust 2018 release.

### Testing
To make sure no regressions were introduced, all tests should be run before sending a pull request. The following command can be run to test Alacritty:
```
cargo test
```
Additionally if there's any functionality included which would lend itself to additional testing, new tests should be added. These can either be in the form of Rust tests using the `#[test]` annotation, or Alacritty's ref tests.
To record a new ref test, a release version of the patched binary should be created and run with the `--ref-test` flag. After closing the Alacritty window, or killing it (`exit` and `^D` do not work), some new files should have been generated in the working directory. Those can then be copied to the `./tests/ref/NEW_TEST_NAME` directory and the test can be enabled by editing the `ref_tests!` macro in the `./tests/ref.rs` file. When fixing a bug, it should be checked that the ref test does not complete correctly with the unpatched version, to make sure the test case is covered properly.
### Performance
Alacritty mainly uses the [vtebench](https://github.com/jwilm/vtebench) tool for testing Alacritty's performance. Any change which could have an impact on Alacritty's performance, should be tested with it to prevent potential regressions.
### Documentation
Code should be documented where appropriate. The existing code can be used as a guidance here and the general `rustfmt` rules can be followed for formatting.
Make all configuration fields optional All configuration fields now have fallback values which will be used if the field is not present. This includes mouse, key bindings and platform specific differences. The mouse and key bindings are now filled by default, if the user rebinds a default mapping, it will be overwritten. To unbind a default binding, it can be mapped to `chars: ""`. Since all platform differences can now be correctly handled by the `src/config/mod.rs` code, it's no longer necessary to maintain separate configuration files, so the `alacritty_macos.yml` and `alacritty_windows.yml` have been deleted. Fixes #40. Fixes #1923.

If any change has been made to the `config.rs` file, these changes should also be documented in the example configuration file `alacritty.yml`.

Changes compared to the latest Alacritty release which have a direct effect on the user (opposed to things like code refactorings or documentation/tests) additionally need to be documented in the `CHANGELOG.md`. The existing entries should be used as a style guideline. The change log should be used to document changes from a user-perspective, instead of explaining the technical background (like commit messages). More information about Alacritty's change log format can be found [here](https://keepachangelog.com).
### Style
Add rustfmt style guide

All Alacritty changes are automatically verified by CI to conform to its rustfmt guidelines. If a CI build is failing because of formatting issues, you can install rustfmt using `rustup component add rustfmt` and then format all code using `cargo fmt`.
