skeleton files in sub-directories

skeleton files in sub-directories

[Reza Alizadeh Majd]

Hi Guix, 

I want to add a series of configuration files to each user's home directory. for this 
I could use skeletons in operating system definitions. 

the problem is that some of these skeletons are located in sub-directories, for 
example `~/.local/share/foo/bar.cfg`. and when I run `guix system reconfigure`
I receive errors about missing parent directory (`~/.local/share/foo` in this example).

is there any way to create parent directories before copying the skeleton files? 


Thanks,
Reza

I think you can do something like:

  (define dot-config
    (compute-file "dot-config-skeleton"
                  #~(begin
                      (mkdir #$output)
                      (mkdir (string-append #$output "/guix"))
                      …)))

and then add it in the list of skeletons like so:

  `(…
    (".config" ,dot-config))

Does that make sense?

I think mkdir-p is a better option here.
It will create all missing directories so there's no need to run 2 mkdir
commands, and won't give an error if the directories already exist.

Hi, 

using `computed-file` to create the parent directories for config files, fixed the issue.
