By default, it installs #{TreeSitter.latest_version()} but you

can configure it in your config files, such as:

|
|
|
config :tree_sitter, :version, "#{TreeSitter.latest_version()}"

## Options
|
|
|
|
* `--runtime-config` - load the runtime configuration
|
|
before executing command
|
|
|
|
* `--if-missing` - install only if the given version
|
|
does not exist
