Zsh: source scripts recursively

scriptingzsh

I have ~/scripts/ folder that contains multiple subfolders with arbitrary directory levels.

This folder only for scripts that need to be sourced when start zsh, how to recursively source all files under its folder and its subfolders in an short and effective way?

Sourcing all non-hidden regular files in there, in collation order:

for f (~/scripts/**/*(N.))  . $f

I would suggest however that you name those files using a specific template like with a .zsh extension (and use *.zsh instead of * above) to avoid problems if there are backup files lying about in there for instance.

Or you could at least exclude some common ones like file~, file.dpkg-dist, file.back...:

set -o extendedglob
for f (~/scripts/**/^*("~"|dpkg-(dist|old|new)|.(tmp|back|bak))(N.))  . $f

etc.

ZSH: Globbing the first N files under a path in lexicographic order

It's zsh, so indeed there's a glob qualifier for that.

echo *([1,42])         # The first 42 files in the current directory, in lexicographic order
echo **/*([1,42])      # The first 42 files in a depth-first traversal
echo **/*(od[1,42])    # The first 42 files in a breadth-first traversal

Other qualifiers that might be useful, for example the following expression includes dot files (D), restricts to regular files (.) and symbolic links (-) to regular files, and expands to an empty list if there is no match (N):

echo *(-.DN[1,42])

Path_helper and zsh

Have you seen this, superuser.com on a similar issue? The linked blog post says (and I quote almost the complete post):

/usr/libexec/path_helper, which Mac OS X runs every time a login shell is created, is really slow. (In particular, I think the slowness is in [[ "$NEWPATH" = *(*:)${p}*(:*) ]].) My Terminal windows were taking about four seconds to open. By removing the files in /etc/paths.d and putting their contents directly into my $PATH in .bash_profile, Terminal windows now load instantly.

The discussion also includes a link to a replacement written in Perl, github.com/mgprot/path_helper (no idea about its speed, tho).

Edit: From the aforementioned blog post's comments - a patch to path_helper that should be another way to fix the issue.
