Add support for GLJPATH environment variable#89ingydotnet wants to merge 10 commits intoglojurelang:mainfrom
Conversation
To avoid adding things that are often lying around... The .clj and .glj are to ignore top level scripts for testing stuff. The GNUmakefile and .cache are for alternate Makefile stuff like I do in glojurelang#75 If that doesn't get merged I can just symlink to it since GNUmakefile has precedence over Makefile (for GNU make).

thanks for adding the GLJPATH support! left a few comments, mainly on command line parsing and the command line interface

love that we're testing the edge case here! re test directory, i think it'd be preferable to use a temp directory rather than the working directory. os.TempDir will return the path to use for temporary files on the current platform

i should have called this out in the prior command line flag PR, but as this is getting more involved, let's use the standard library's flag parsing: https://pkg.go.dev/flag
pkg/gljmain/gljmain.go

this seems duplicative with GLJPATH, and "include" evokes C/C++ — i'm not sure the -I command line flag makes sense for clojure

could we could drop the true second arg and start iterating from index 0 to get the same result?

This all makes sense. I'll update in the morning.

We probably want . at the very end of the loadpath (which is what you had).
It seems like there is 1 other entry in the loadpath when we start adding things here, but I was unable to print its value.
The other things need to be added to the front of the loadpath as I'm doing.
I'll refactor to make 2 funcs: AddLoadPath (same as original) and PrependLoadPath.
$ GLJPATH=foo:bar ./bin/linux_amd64/glj -e '*glojure-load-path*'
("foo" "bar" "<StdLib>" ".")

For runtime loading of
.gljfiles.Note: this PR includes #88 commits so that one should probably be sorted first.
I can adjust this one to any changes you want there.
