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
|
|
help : show this help text
|
|
install (repo or name) : 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.
|
|
run rule : run a rule. Can also run custom rules added via (phony "task" [deps...] ...)
|
|
or (rule "ouput.file" [deps...] ...).
|
|
rules : list rules available with run.
|
|
update-pkgs : Update the current package listing from the remote git repository selected.
|
|
quickbin entry executable : Create an executable from a janet script with a main function.
|
|
|
|
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.
|
|
--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).
|
|
--pkglist : URL of git repository for package listing. Defaults to $JANET_PKGLIST or https://github.com/janet-lang/pkgs.git
|
|
|
|
Flags are:
|
|
--verbose : Print shell commands as they are executed.
|
|
--test : If passed to jpm install, runs tests before installing. Will run tests recursively on dependencies.
