Implementations

impl ScriptingEnvironment

pub fn detect() -> Self

Detect available scripting environments The process-wide detection result, computed on first call.

Prefer this over Self::detect_uncached everywhere: runtimes do not appear and disappear while NetGet runs, and probing per AppState costs four subprocess spawns each time for an answer that cannot have changed.

pub fn detect_uncached() -> Self

Run the probes. Public for the one caller that genuinely wants to re-probe.

pub fn probe(program: &str, args: &[&str]) -> Option<String>

Run <program> --version with a deadline, returning its trimmed output.

The child is killed if it outlives [PROBE_TIMEOUT], because the alternative is Command::output()’s behaviour: block on the stdout pipe until the child exits, with no way out.

pub fn probe_with_timeout( program: &str, args: &[&str], timeout: Duration, ) -> Option<String>

Explicit budget is useful for callers probing a custom runtime.

pub fn is_available(&self, language: ScriptLanguage) -> bool

Check if a specific language is available

pub fn get_version(&self, language: ScriptLanguage) -> Option<&str>

Get version string for a language

pub fn format_available(&self) -> String

Format available environments for display to user/LLM

pub fn warn_if_unavailable(&self, language: ScriptLanguage)

Warn if language is not available
