Contributions

• If you are new to VS Code language extensions, you may read Language Extensions Overview. Moreover, you may read this TextMate manual and this tutorial for TextMate grammar.
• If you want to play with this project, you can download it and run npm i in the terminal to install the required dependencies. Then, you may make some changes in /syntaxes-yaml/sas.tmLanguage.yaml and then press F5 to see the effect.

More

• I develop this project because I need a SAS syntax highlighter to facilitate my work, but the existing SAS syntax highlighters have some bugs in my SAS code. Thus, I focus only on the syntax I need but do not exclude the possibility of implementing more syntax highlighting.
• Not until developing the TextMate grammar for SAS did I realise it was pretty tough. The reason is SAS syntax has no simple but universal rules.
• If you like this extension, you may buy me a coffee.
• Enjoy!
