Recursively source files under a folder except *.bak

Question

As title howto source all files under a folder recursively except files that end with .bak

Answer 1

Setting wildignore can have quite a few side effects (especially if done globally).

So I would do:

let s:prefix = '/path/to/folder'

let files = filter(glob(prefix . '/**/*.bak', 1, 1), "fnamemodify(v:val, ':e') != 'bak'")

for fname in files
    execute 'source' fname
endfor

Answer 2

You can only 'source' a file at a time. Therefore, build the list of files first, and then source them one by one.

set wildignore=*.bak
let s:prefix = '/path/to/folder'

for s:fname in glob(s:prefix . '/**', 0, 1)
    execute 'source' s:fname
endfor

However, normally you should only source *.vim files, so then it becomes

let s:prefix = '/path/to/folder'

for s:fname in glob(s:prefix . '/**/*.vim', 1, 1)
    execute 'source' s:fname
endfor

But note that file system search does not guarantee order, so there can be some side-effects.
