Command-line Options
just supports a number of useful command-line options for listing, dumping,
and debugging recipes and variables:
$ just --list
Available recipes:
js
perl
polyglot
python
ruby
$ just --show perl
perl:
#!/usr/bin/env perl
print "Larry Wall says Hi!\n";
$ just --show polyglot
polyglot: python js perl sh ruby
Setting Command-line Options with Environment Variables
Some command-line options can be set with environment variables
For example, unstable features can be enabled either with the --unstable
flag:
$ just --unstable
Or by setting the JUST_UNSTABLE environment variable:
$ export JUST_UNSTABLE=1
$ just
Since environment variables are inherited by child processes, command-line
options set with environment variables are inherited by recursive invocations
of just, where as command line options set with arguments are not.
Consult just --help for which options can be set with environment variables.
