Path environment

Parse and expose both PATH and PATHEXT environment variables and allow to find an executable with the same rules as the shell.

API

type BlackFox.PathEnvironment =
    // Directories in the system PATH.
    path: string []

    // Extensions considered executables by the system.
    // Parsed from `PATHEXT` on windows and always return `[""]` on other systems.
    pathExt: string []

    // Find an executable on the PATH
    findExecutable: name: string -> includeCurrentDirectory: bool -> string option

    // Find a file on the PATH
    findFile: name: string -> includeCurrentDirectory: bool -> string option

Example

open BlackFox

| nodePath -> // ...
