func ClampToRange ¶ added in v1.10.0

func ClampToRange(version, min, max string) string

ClampToRange checks if version falls within [min, max] and returns the best installed version within range if it doesn't. Returns the original version if min/max are empty or the version is already in range. This is used to respect framework PHP version constraints during site linking.

func CompareMajorMinor ¶ added in v1.26.0

func CompareMajorMinor(a, b string) int

CompareMajorMinor compares two "major.minor" version strings numerically and returns -1, 0, or 1. An unparseable version sorts below any numeric one.

func DetectExtensions ¶ added in v0.5.5

func DetectExtensions(dir string) []string

DetectExtensions reads composer.json in dir and returns the list of PHP extensions declared in the require map (ext-* keys), with the "ext-" prefix stripped. Returns an empty slice on any error (non-fatal).

func DetectVersion ¶

func DetectVersion(dir string) (string, error)

DetectVersion detects the PHP version for the given directory. It checks, in order:

1. .lerd.yaml php_version field (explicit lerd override)
2. .php-version file (explicit per-project pin)
3. composer.json require.php semver (project requirement)
4. global config default

func DetectVersionClamped ¶ added in v1.11.0

func DetectVersionClamped(dir, phpMin, phpMax, fallback string) string

DetectVersionClamped detects the PHP version and clamps it to the given range. If phpMin/phpMax are empty, no clamping is applied.

func FPMInstalled ¶ added in v1.27.0

func FPMInstalled(version, container string) bool

FPMInstalled reports whether the FPM container already exists (so it only needs starting) rather than needing a fresh build. It checks both the shared per-version units and the specific container's unit, so a custom-FPM container (lerd-cfpm-<site>, whose version isn't in the shared list) is recognised too.

func IsInstalled ¶

func IsInstalled(version string) bool

IsInstalled returns true if the given PHP version has an FPM quadlet.

func IsPHPProject ¶ added in v1.23.0

func IsPHPProject(dir string) bool

IsPHPProject reports whether dir looks like a PHP project: it has a composer.json or any top-level .php file. Static sites (a public dir with no PHP) and non-PHP projects return false, so callers can hide PHP-only surfaces like the version dropdown, Tinker, Xdebug, dumps and FPM logs.

func ListInstalled ¶

func ListInstalled() ([]string, error)

ListInstalled returns all PHP versions that have an FPM quadlet file or a running/existing Podman container, e.g. ["8.3", "8.4"]. The two sources are merged so users whose quadlet file is missing but whose container still exists are not excluded.

func SiteUsesPHP ¶ added in v1.23.0

func SiteUsesPHP(s config.Site) bool

SiteUsesPHP reports whether the site is a PHP project served by lerd's PHP runtime (the shared FPM image or FrankenPHP), as opposed to a static site or a custom container. It mirrors the registration decision in cli.RegisterProject: a framework, a composer.json / top-level .php file, or a public dir with an index.php entrypoint all count as PHP. Custom containers and static sites (a public dir of HTML only) return false.

func StartFPM ¶ added in v1.27.0

func StartFPM(version, container string) error

StartFPM brings up a stopped-but-installed FPM container and waits for it to report running, so an exec right after doesn't race the boot. It is a no-op when the container is already running and returns ErrFPMNotInstalled (wrapped with the version) when the container doesn't exist yet. It produces no output; callers add any user-facing progress. Shared by the CLI php/artisan/shell commands and the MCP exec handlers so both auto-start the same way.
