SUMMARY
|
|
|
|
Compile the Tree-sitter WASM library. This will create two files in the
|
|
\`lib/binding_web\` directory: \`tree-sitter.js\` and \`tree-sitter.wasm\`.
|
|
|
|
REQUIREMENTS
|
|
|
|
You must have the \`docker\` command on your PATH for this to work.
|
|
|
|
OPTIONS
|
|
|
|
--debug: Compile the library more quickly, with fewer optimizations and more runtime assertions.
