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).
Commands that need write permission to the modpath are considered privileged commands - in
some environments they may require super user privileges.
Other project-level commands need to have a ./project.janet file in the current directory.
Subcommands are:
build : build all artifacts
Unprivileged global subcommands:
help : show this help text
show-paths : prints the paths that will be used to install things.
quickbin entry executable : Create an executable from a janet script with a main function.
Privileged global subcommands:
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.
show-paths : prints the paths that will be used to install things.
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.
clear-manifest : clear the manifest. Useful for fixing broken installs.
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.
rule-tree (root rule) (depth) : Print a nice tree to see what rules depend on other rules.
Optinally provide a root rule to start printing from, and a
max depth to print. Without these options, all rules will print
their full dependency tree.
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.
make-lockfile (lockfile) : Create a lockfile based on repositories in the cache. The
lockfile will record the exact versions of dependencies used to ensure a reproducible
build. Lockfiles are best used with applications, not libraries. The default lockfile
name is lockfile.jdn.
load-lockfile (lockfile) : Install modules from a lockfile in a reproducible way. The
default lockfile name is lockfile.jdn.
update-pkgs : Update the current package listing from the remote git repository selected.
Privileged project subcommands:
deps : install dependencies for the current project.
install : install artifacts of the current project.
uninstall : uninstall the current project's artifacts.
Unprivileged project subcommands:
build : build all artifacts
clean : remove any generated files or artifacts
test : run tests. Tests should be .janet files in the test/ directory relative to project.janet.
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.
rule-tree (root rule) (depth) : Print a nice tree to see what rules depend on other rules.
Optionally provide a root rule to start printing from, and a
max depth to print. Without these options, all rules will print
their full dependency tree.
debug-repl : Run a repl in the context of the current project.janet file. This lets you run rules and
otherwise debug the current project.janet file.
