I like the command name 'mim' (which Merriam-Webster tells me is an
adjective meaning 'affectedly shy or modest'). By extension I think the
file should be called 'Mimfile'. This avoids any misleading reference to
make. As Eli correctly points out (and I should have) the script misses
the main distinguishing feature of make, that it handles dependencies.
I've tidied up the script a bit. Its usage is:
mim [-f FILE] [SHELL_OPTIONS] [TARGET] ...
Some implementation details are exposed which differ from make:
- The default FILE is 'Mimfile' but an alternative name can be provided.
- SHELL_OPTIONS are consumed by the shell that runs the generated script.
'-x' and '-v' might be useful.
- Unlike with make arguments after TARGET aren't treated as additional
targets, instead they're made available to the script that's run.
Essentially mim is a way to specify commands that take the form:
mim sub_command sub_command_options...
The new script is attached. I've also made a patch to incorporate the
script into BusyBox, though whether it will prove acceptable is out of
my hands.
