This project represents a playground for textX language. Users can define a new language by specifying its grammar using textX. They can also create a program that should follow the grammar of the defined language.
Some parts of the code are taken from the following projects:
- textX-LS - textX server implementation with pygls
- textx-gen-coloring - grammar parser for syntax highlighting
- monaco-languageclient - language client creation with language server running in web worker
The project is deployed and you can create and validate your new language using textX at textx.github.io/textx-playground.
This is a web application with only one page, containing a header and two code editors.
One editor is used for specifying language grammar and the second for defining a model (program) using newly defined language. Each editor contains the status bar, which has one of the following states:
- loading - until textX server is started
- error - shows error in grammar/model with message and position (row, column)
- valid - grammar/model is valid
The header contains textX logo, toggler between light and dark theme, and links to documentation and GitHub repository.
Grammar and model content can be shared via link by clicking the share icon in the top right corner. Their content is shortened using LZ compression and embedded into the URL link as a query parameter. When this link is opened, the editors' content is restored from the query parameter.
Basic syntax highlighting is implemented. Grammar and model keywords and comments are highlighted.
After cloning the repo and installing dependencies with npm i command, the project is started by running:
npm run dev -- --port 3000
The project is built with:
npm run build
