Module cli_tools 

CLI tool detection for cli-tool nodes.

The Node Hub asks “is the binary this cli-tool node needs installed, and is it at least the minimum version the entry declares?”. This module answers the first half - it probes the machine by running <name> <version_command> (default --version) and parsing a version token out of the output. The minimum-version verdict is computed by the caller (the frontend) so the probe stays a pure “what’s installed?” query and the command is reusable.

Spawning mirrors the adapters’ tokio::process::Command::new(CLI) pattern, so no extra Tauri plugin or shell capability is required.

Structs

CliToolStatus

Outcome of probing the machine for one CLI tool. found distinguishes “binary missing from PATH” from “present but version unparseable”. Never surfaced as an Err so the Hub renders a badge instead of failing.

Functions

detect_cli_tool

Probe for name <version_command>. Returns found: false (never an Err) when the binary can’t be spawned or the name is rejected.

parse_version

Extract the first dotted numeric version token (\d+(\.\d+)+) from text. Bare integers and dash-separated dates (2024-01-02) are skipped so a build date or revision number isn’t mistaken for a version.
