Resolve and validate a Quarto CLI version

Internal helper used by generate_dockerfile() when install_quarto = TRUE. If quarto_version is "latest", queries the Quarto releases API to resolve it to a concrete version at generation time, so the version actually pinned into the Dockerfile is recorded rather than left as a moving target. If an explicit version is supplied, validates its format and confirms a matching GitHub release actually exists, so a typo or unreleased version fails here rather than producing a Dockerfile that 404s at build time.

Usage

.get_quarto_version(quarto_version = "latest", verbose = FALSE)

Arguments

quarto_version

Character string. Either "latest" or an explicit Quarto version, e.g. "1.5.57".

verbose

Logical. If TRUE, prints progress messages during resolution. Defaults to FALSE.

Value

Character string. The resolved version, without a leading "v" (e.g. "1.5.57"), suitable for interpolating directly into Quarto's versioned download URL.
