dired-omit-files regex

[srustamo]

I think I understand the intention of this regex below. It looks for for files in dired, which:

• start with one ore more '.' (first grouping)
• have 'aux' or 'log' etc after the first grouping
• or compile_commands.json
• or 'pycache'

If it is so, it does not seem to work on `.log' files.

Is my understanding correct? Or does this regex do something else?

(setq dired-omit-files "\\(?:.*\\.\\(?:aux\\|log\\|pickle\\|synctex\\.gz\\|run\\.xml\\|bcf\\|am\\|in\\|blx\\.bib\\)\\'\\)\\|compile_commands.json\\|__pycache__")

This line is from here

Looks like I have the old version of this file, still, could you please explain the old regex?

Dot followed by one of the extensions in the group is omitted. Works on log files too.

[srustamo]

Why not use dired-omit-extensions from diredx package, which you require on the top of the file?

It's more flexible, see dired-omit-regexp function.

By default, dired-omit-extensions seems to contain many extensions. Do you set this var to nil?

dired-omit-extensions is a variable defined in ‘dired-x.el’. Its value is (".o" "~" ".bin" ".lbin" ".so" ".a" ".ln" ".blg" ".bbl" ".elc" ".lof" ".glo" ".idx" ".lot" ".svn/" ".hg/" ".git/" ".bzr/" "CVS/" "_darcs/" "_MTN/" ".fmt" ".tfm" ".class" ".fas" ".lib" ".mem" ".x86f" ".sparcf" ".dfsl" ".pfsl" ".d64fsl" ".p64fsl" ".lx64fsl" ".lx32fsl" ".dx64fsl" ".dx32fsl" ".fx64fsl" ".fx32fsl" ".sx64fsl" ".sx32fsl" ".wx64fsl" ".wx32fsl" ".fasl" ".ufsl" ".fsl" ".dxl" ".lo" ".la" ".gmo" ".mo" ".toc" ".aux" ".cp" ".fn" ".ky" ".pg" ".tp" ".vr" ".cps" ".fns" ".kys" ".pgs" ".tps" ".vrs" ".pyc" ".pyo" ".idx" ".lof" ".lot" ".glo" ".blg" ".bbl" ".cp" ".cps" ".fn" ".fns" ".ky" ".kys" ".pg" ".pgs" ".tp" ".tps" ".vr" ".vrs")

dired-omit-files completely overrides dired-omit-extensions. I adjust dired-omit-files to my personal use, e.g. I never have .vrs files, I don't ignore them.

[srustamo]

Thanks. Do you use ranger.el by any chance?

[abo-abo]

No.
