Documentation

Overview

Package moustache implements pkgx's `{{token}}` template substitution, a faithful port of libpkgx's useMoustaches. Build and test scripts, env values and fixtures are expanded with it before they run.

Functions

func Apply

func Apply(input string, tokens []Token) string

Apply substitutes every token in input. The pattern mirrors libpkgx exactly: `(^\$)?{{\s*<from>\s*}}` — optional surrounding whitespace, and a single leading `$` (at the very start) is consumed so `${{prefix}}` yields the value without the dollar. Replacement is literal (a To containing `$` is safe).

Types

type Dep

type Dep struct {
	Project string
	Version string
	Path    string
}

Dep is an installed dependency contributing deps.<Project>.* tokens.

type Token

type Token struct{ From, To string }

Token is a single substitution: every `{{ From }}` becomes To.

func Deps

func Deps(deps []Dep) []Token

Deps returns the tokens for a build's resolved dependencies.

func Host

func Host(arch, triple, platform string, concurrency int) []Token

Host returns the {{hw.*}} tokens describing the build TARGET.

func Prefix

func Prefix(installPath string) []Token

Prefix returns the {{prefix}} token (the package's install path).

func Version

func Version(version, prefix string) []Token

Version returns the version tokens for a version string under prefix (usually "version", or "deps.<project>.version" for a dependency).
