option to set "root" path

[nkh]

it seems that the location when running lscolors changes the way its input is colored

when in another directory and with the same input, colors differ; also note that the some files are colored as they should, one of the files is executable and doesn't have the same color but that's understandable.

I run lscolors in a subshell as a fix it but it may surprise some users and it would be more usable if the result is the same, and for users without a sub shell an option to set the "root" path may be helpful.

Please tell us exactly how you run lscolors

In many ways but most often in a pipe.

You may not remember me but I'm the one who asked you to extract lscolors as a utility.

You could use a subshell for this, e.g.

fd | (cd dir && lscolors) | ...

However, I do notice one quality-of-life thing we could improve: right now if any directory component doesn't exist, we treat it like a normal file. Presumably we should only do that for the final component, and everything else should default to the directory color.

@tavianator

from my first post

I run lscolors in a subshell as a fix it ...

but it may surprise some users ...

and it would be more usable if the result is the same  ...

and for users without a sub shell an option to set the "root" path may be helpful.

And yes please paths that don't exists should still look like paths. For executable files a "root" path would be necessary as I suggested.

this is useful when one has a list of paths to display, want to remove parts of the path (because it's too long for example) and still have colors.

[sharkdp]

Thank you for reporting this. It would be of great help if you could a small example on how to reproduce this. And maybe summarize the suggested improvements (add root path option + colorize non-terminal folders + ...).

Hi, sorry I was clear enough about the context.

mkdir subdir 
touch subdir/f.jpg
touch subdir/f.exe
chmod a+x subdir/f.exe

fd . subdir > found
<found lscolors

mkdir other_sub
cd other_sub
<../found lscolors # colors will differ here

Possible improvements:

• path could always be colored if it looks like a path, as named by tavianator
• files could always be colored (they are)
• files that need to be accessed could use the --root option
  • but "root" is pre-pended to all input

root="$PWD"
cd a_galaxy_far_far_away 
<found lscolors --root "$root"
