Quite often, we might want to work with collections of J scripts which
are outside the standard J system and user directories.
It's quite possible, though obscure, to use introspection (4!:4 and
4!:3) to locate scripts relative to the currently executing script.
It would probably be better to make this be an explicitly supported
feature of J's load verb.
Specifically, I would like to propose that while load is executing,
jpath would expand ~dir/ to be the innermost referenced directory of
the currently executing load.
In other words:something like
load=: {{
0 load y
:
fls=. getscripts_j_ y
fn=. ('script',x#'d')~
for_fl. fls do.
SystemFolders_j_=: SystemFolders_j_,~ 'dir';fpath_j_;fl
if. Displayload_j_ do. echo;fl end.
if. -. fexist fl do.
echo 'not found: ',;fl
end.
fn fl
SystemFolders_j_=: (<<<({."1 SystemFolders_j_)i.<'dir') { SystemFolders_j_
Loaded_j_=: ~. Loaded_j_,fl
end.
EMPTY
}}
Thoughts? Objections? Improvements?
Thanks,
