+# [# 0.7.0 (2020-04-13) - New Parser is 67% faster](https://github.com/boa-dev/boa/compare/v0.6.0...v0.7.0)
+
+`v0.7.0` brings a REPL, Improved parser messages and a new parser!
+This is now the default behaviour of Boa, so running Boa without a file argument will bring you into a javascript shell.
+Tests have also been moved to their own files, we had a lot of tests in some modules so it was time to separate.
+
+## New Parser
+
+Most of the work in this release has been on rewriting the parser. A big task taken on by [HalidOdat](https://github.com/HalidOdat), [Razican](https://github.com/Razican) and [myself](https://github.com/jasonwilliams).
+
+The majority of the old parser was 1 big function (called [`parse`](https://github.com/boa-dev/boa/blob/019033eff066e8c6ba9456139690eb214a0bf61d/boa/src/syntax/parser.rs#L353)) which had some pattern matching on each token coming in.\
+The easy branches could generate expressions (which were basically AST Nodes), the more involved branches would recursively call into the same function, until eventually you had an expression generated.
+
+This only worked so far, eventually debugging parsing problems were difficult, also more bugs were being raised against the parser which couldn't be fixed.
+
+We decided to break the parser into more of a state-machine. The initial decision for this was inspired by [Fedor Indutny](https://github.com/indutny) who did a talk at (the last) JSConf EU about how he broke up the old node-parser to make it more maintanable. He goes into more detail here https://www.youtube.com/watch?v=x3k_5Mi66sY&feature=youtu.be&t=530
+
+The new parser has functions to match the states of parsing in the spec. For example https://tc39.es/ecma262/#prod-VariableDeclaration has a matching function `read_variable_declaration`. This not only makes it better to maintain but easier for new contributors to get involed, as following the parsing logic of the spec is easier than before.
+
+Once finished some optimisations were added by [HalidOdat](https://github.com/HalidOdat) to use references to the tokens instead of cloning them each time we take them from the lexer.\
+This works because the tokens live just as long as the parser operations do, so we don't need to copy the tokens.\
+What this brings is a huge performance boost, the parser is 67% faster than before!

+# [# 0.6.0 (2020-02-14) - Migration to Workspace Architecture + lexer/parser improvements](https://github.com/boa-dev/boa/compare/v0.5.1...v0.6.0)
+
+The lexer has had several fixes in this release, including how it parses numbers, scientific notation should be improved.
+On top of that the lexer no longer panics on errors including Syntax Errors (thanks @adumbidiot), instead you get some output on where the error happened.
+
+## Moving to a workspace architecture
+
+Boa offers both a CLI and a library, initially these were all in the same binary. The downside is
+those who want to embed boa as-is end up with all of the command-line dependencies.
+So the time has come to separate out the two, this is normal procedure, this should be analogous to ripgrep
+and the regex crate.
+Cargo has great support for workspaces, so this shouldn't be an issue.
+

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+ and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+ community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+ any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+ without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[discord](https://discord.gg/tUFFk9Y) by contacting anyone in the _@boa_dev_
+group (check the yellow usernames).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.1, available at
+[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].
+
+Community Impact Guidelines were inspired by
+[Mozilla's code of conduct enforcement ladder][mozilla coc].

+# Contributing to Boa
+
+Boa welcomes contribution from everyone. Here are the guidelines if you are
+thinking of helping out:
+
+## Contributions
+
+Contributions to Boa or its dependencies should be made in the form of GitHub
+pull requests. Each pull request will be reviewed by a core contributor
+(someone with permission to land patches) and either landed in the main tree or
+given feedback for changes that would be required. All contributions should
+follow this format.
+
+Should you wish to work on an issue, please claim it first by commenting on
+the GitHub issue that you want to work on it. This is to prevent duplicated
+efforts from contributors on the same issue.
+
+Head over to [issues][issues] and check for "good first issue" labels to find
+good tasks to start with. If you come across words or jargon that do not make
+sense, please ask!
+
+If you don't already have Rust installed [_rustup_][rustup] is the recommended
+tool to use. It will install Rust and allow you to switch between _nightly_,
+_stable_ and _beta_. You can also install additional components. In Linux, you
+can run:
+
+```shell
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+
+Then simply clone this project and `cargo build`.
+
+### Running the compiler
+
+You can execute a Boa console by running `cargo run`, and you can compile a list
+of JavaScript files by running `cargo run -- file1.js file2.js` and so on.
+
+### Debugging
+
+Knowing how to debug the interpreter should help you resolve problems quite quickly.
+See [Debugging](./docs/debugging.md).
+
+### Web Assembly
+
+If you want to develop on the web assembly side you can run `yarn serve` and then go
+to .
+
+### boa-unicode
+
+Boa uses the library `boa-unicode` to query Unicode character properties and classes in lexer and parser. See [boa_unicode/README.md](./boa_unicode/README.md) for development and more information.
+
+### Setup
+
+#### VSCode Plugins
+
+Either the [Rust (RLS)][rls_vscode] or the [Rust Analyzer][rust-analyzer_vscode]
+extensions are preferred. RLS is easier to set up but some of the development is
+moving towards Rust Analyzer. Both of these plugins will help you with your Rust
+Development
+
+#### Tasks
+
+There are some pre-defined tasks in [tasks.json](.vscode/tasks.json)
+
+- Build - shift+cmd/ctrl+b should build and run cargo. You should be able to make changes and run this task.
+- Test - (there is no shortcut, you'll need to make one) - Runs `Cargo Test`.
+ I personally set a shortcut of shift+cmd+option+T (or shift+ctrl+alt+T)
+
+If you don't want to install everything on your machine, you can use the Dockerfile.
+Start VSCode in container mode (you may need the docker container plugin) and use the Dockerfile.
+
+## Testing
+
+Boa provides its own test suite, and can also run the official ECMAScript test suite. To run the Boa test
+suite, you can just run the normal `cargo test`, and to run the full ECMAScript test suite, you can run it
+with this command:
+
+```shell
+cargo run --release --bin boa_tester -- run -v 2> error.log
+```
+
+Note that this requires the `test262` submodule to be checked out, so you will need to run the following first:
+
+```shell
+git submodule init && git submodule update
+```
+
+This will run the test suite in verbose mode (you can remove the `-v` part to run it in non-verbose mode),
+and output nice colorings in the terminal. It will also output any panic information into the `error.log` file.
+
+You can get some more verbose information that tells you the exact name of each test that is being run, useful
+for debugging purposes by setting up the verbose flag twice, for example `-vv`. If you want to know the output of
+each test that is executed, you can use the triple verbose (`-vvv`) flag.
+
+If you want to only run one sub-suite or even one test (to just check if you fixed/broke something specific),
+you can do it with the `-s` parameter, and then passing the path to the sub-suite or test that you want to run. Note
+that the `-s` parameter value should be a path relative to the `test262` directory. For example, to run the number
+type tests, use `-s test/language/types/number`.
+
+Finally, if you're using the verbose flag and running a sub suite with a small number of tests, then the output will
+be more readable if you disable parallelism with the `-d` flag. All together it might look something like:
+
+```shell
+cargo run --release --bin boa_tester -- run -vv -d -s test/language/types/number 2> error.log
+```
