Some of the high-level features include:

syntax.NOTE: Due to Crystal's current limitations with compiling on Windows, Myst only works on macOS and Linux systems.
The recommended method of installing Myst is with mtenv
, the official version manager for the Myst language. It is available here and has installation instructions available in the README.
For now, you will need to have Crystal installed to be able to install Myst. See Crystal's installation instructions for how to get started. Myst currently runs on Crystal 0.27.0.
Once Crystal and mtenv
are installed, installing Myst is as simple as running mtenv install
:
# Make sure mtenv is properly set up
mtenv setup
# Install v0.6.2 of Myst
mtenv install v0.6.2
# Make it the active version
mtenv use v0.6.2
With that, myst
should now be installed and ready to go!
Help with improving these installation instructions, making pre-built binaries, and/or managing releases would be greatly appreciated :)
If you have an idea for a new feature or find a bug in Myst, please file an issue for it!. Using the language and finding bugs are the best ways to help Myst improve. Any and all help here is appreciated, even if that just means trying out the language for a day.
If you just want to get involved in the community, come hang out in our Discord server!. We're a pretty small community, so there's plenty of room for anyone that would like to hang out, even if it has nothing to do with Myst!
When I can, I try to label issues with help wanted
or good first issue
. help wanted
is for issues that I'd really like external input on, while good first issue
is for issues that can be implemented without too much knowledge of how the lexer/parser/interpreter works. On these issues, I try to explain as much as possible about what the solution looks like, including files that will need editing and/or methods that need implementing/changing. I hope that helps!
If you'd like to tackle something, but don't know where to start, please let me know! I'd love to help you get involved, so feel free to ask in the discord server or message me directly (faulty#7958 on discord, or email also works) and I'll do my best to get you up and running.
If you would like to contribute to Myst's development, just:
git checkout -b my-new-feature
)git commit -am 'Add some feature'
)git push origin my-new-feature
)If you have a specific issue that you'd like to tackle, be sure to add a comment saying you're working on it so that everyone is aware! (currently, github doesn't allow for assigning issues to new contributers :/)
Also, "ownership" is not binding. It's just a way of saying "hey, I think I can work on this!". If you get stuck or need help moving forward, feel free to ask for help either on the issue itself, or in the discord server.
Most importantly, don't feel bad if you bite off more than you can chew. Issues can easily end up being far more complex than they appear at the start, especially on a project of this size. But don't give up! It's always hard to get started on an existing project, but I want to help and make it as easy as possible wherever I can!
