.deps.check

Liatir.deps.check() checks whether one command-line binary is available, preferring a verified bundled tool and then checking the host search path (PATH).

Signature

check(binary: string): Promise<DepCheckResult>

check(binary) -> dict

check(binary)

INFO

Liatir provides managed Rust and C++ libraries for Native/WASM Plugins. This app bridge is Native-only; WASM stays isolated.

check(binary: &str) -> Result<Value>

C++ example setup.

auto result = liatir::invoke("lia_deps_check", {{"binary", "samtools"}});

Example

const samtools = await Liatir.deps.check('samtools');

if (!samtools.available) {
  console.warn('Samtools is not available.');
}

samtools = ctx.liatir.deps.check('samtools')

if not samtools['available']:
    print('Samtools is not available.')

samtools <- ctx$liatir$deps$check("samtools")
if (!isTRUE(samtools$available)) stop("Samtools is not available")

INFO

Liatir provides managed Rust and C++ libraries for Native/WASM Plugins. This app bridge is Native-only; WASM stays isolated.

let samtools = ctx.liatir.deps().check("samtools")?;
if samtools["available"].as_bool() != Some(true) {
    return Err("Samtools is not available".into());
}

C++ example setup.

auto samtools = liatir::invoke("lia_deps_check", {{"binary", "samtools"}});
if (!samtools.at("available").get<bool>())
    throw std::runtime_error("Samtools is not available");

DepCheckResult

Field	Type	Description
available	boolean / bool	true if the binary is available.
binary	string / str	The name of the binary that was checked.
path	string | null / str | None	Full path to the binary, or null.
source	string	bundled or path: where the tool was resolved.
version	string | null / str | None	Detected version string, or null.

IMPORTANT

DepCheckResult fields are always camelCase in Node, Python, R and Native, because they come from the JSON response of the Liatir bridge.
