It is recommended to use nix to fulfill all development dependencies. To activate the development environment simply run nix-shell in the project root.

Running Tests

To run tests simply run nix-shell --run 'tree-sitter test'.

Quoted Template Expressions

In principle it is allowed to contain arbitary expressions in quoted template interpolations. Consider for example:

foo = "prefix-${func(\"bar\"}"

To make parsing a little easier, this parser only checks for valid escape sequences and template chars. When using this parser one would have to take the content of a template interpolation, unescape it and parse it again to get the syntax tree. The same applies to template directives.

String Literals

String literals are parsed as quoted templates. The calling application should check if the node contains any template interpolations or directives.
