• extraDepTargets : Array Lake.Name

  An Array of target names to build whenever the package is used.

• precompileModules : Bool

  Whether to compile each of the package's module into a native shared library that is loaded whenever the module is imported. This speeds up evaluation of metaprograms and enables the interpreter to run functions marked @[extern].

  Defaults to false.

• moreServerArgs : Array String

  Deprecated in favor of moreGlobalServerArgs. Additional arguments to pass to the Lean language server (i.e., lean --server) launched by lake serve, both for this package and also for any packages browsed from this one in the same session.

• moreGlobalServerArgs : Array String

  Additional arguments to pass to the Lean language server (i.e., lean --server) launched by lake serve, both for this package and also for any packages browsed from this one in the same session.

  The directory containing the package's Lean source files. Defaults to the package's directory.

  (This will be passed to lean as the -R option.)

• releaseRepo? : Option String

  The URL of the GitHub repository to upload and download releases of this package. If none (the default), for downloads, Lake uses the URL the package was download from (if it is a dependency) and for uploads, uses gh's default.

• releaseRepo : Option String

  The URL of the GitHub repository to upload and download releases of this package. If none (the default), for downloads, Lake uses the URL the package was download from (if it is a dependency) and for uploads, uses gh's default.

• buildArchive? : Option String

  A custom name for the build archive for the GitHub cloud release. If none (the default), Lake uses buildArchive, which defaults to {(pkg-)name}-{System.Platform.target}.tar.gz.

• buildArchive : String

  A custom name for the build archive for the GitHub cloud release. Defaults to {(pkg-)name}-{System.Platform.target}.tar.gz.

  Whether to prefer downloading a prebuilt release (from GitHub) rather than building this package from the source when this package is used as a dependency.

• testDriver : String

  The name of the script, executable, or library by lake test when this package is the workspace root. To point to a definition in another package, use the syntax <pkg>/<def>.

  A script driver will be run by lake test with the arguments configured in testDriverArgs followed by any specified on the CLI (e.g., via lake lint -- <args>...). An executable driver will be built and then run like a script. A library will just be built.

• testDriverArgs : Array String

  Arguments to pass to the package's test driver. These arguments will come before those passed on the command line via lake test -- <args>....

• lintDriver : String

  The name of the script or executable used by lake lint when this package is the workspace root. To point to a definition in another package, use the syntax <pkg>/<def>.

  A script driver will be run by lake lint with the arguments configured in lintDriverArgs followed by any specified on the CLI (e.g., via lake lint -- <args>...). An executable driver will be built and then run like a script.

• lintDriverArgs : Array String

  Arguments to pass to the package's linter. These arguments will come before those passed on the command line via lake lint -- <args>....
