Run from a directory containing a project.janet file to perform operations
|
|
on a project, or from anywhere to do operations on the global module cache (modpath).
|
|
|
|
Subcommands are:
|
|
build : build all artifacts
|
|
install (repo) : install artifacts. If a repo is given, install the contents of that
|
|
git repository, assuming that the repository is a jpm project. If not, build
|
|
and install the current project.
|
|
uninstall (module) : uninstall a module. If no module is given, uninstall the module
|
|
defined by the current directory.
|
|
clean : remove any generated files or artifacts
|
|
test : run tests. Tests should be .janet files in the test/ directory relative to project.janet.
|
|
deps : install dependencies for the current project.
|
|
clear-cache : clear the git cache. Useful for updating dependencies.
|
|
|
|
Keys are:
|
|
--modpath : The directory to install modules to. Defaults to $JANET_MODPATH, $JANET_PATH, or (dyn :syspath)
|
|
--headerpath : The directory containing janet headers. Defaults to $JANET_HEADERPATH.
|
|
--binpath : The directory to install binaries and scripts. Defaults to $JANET_BINPATH.
|
|
--libpath : The directory containing janet C libraries (libjanet.*). Defaults to $JANET_LIBPATH.
|
|
--optimize : Optimization level for natives. Defaults to 2.
|
|
--compiler : C compiler to use for natives. Defaults to cc (cl on windows).
|
|
--archiver : C compiler to use for static libraries. Defaults to ar (lib on windows).
|
|
--linker : C linker to use for linking natives. Defaults to cc (link on windows).
|
|
--cflags : Extra compiler flags for native modules.
|
|
--lflags : Extra linker flags for native modules.
|
|
|
|
Flags are:
|
|
--verbose : Print shell commands as they are executed.
