mc-wrapper.sh

[pjc42]

hi, I'd like to write a wrapper script of some kind similar to mc-wrapper: ( mc/contrib/mc-wrapper.sh.in ) so that when I exit mc it exits in current dir of mc not dir mc started in. can you suggest env variables or tmp files you are using to that I can pick up the mc current dir to do this?

thanks

I have dug into this a little more and it is relatively straightforward to add myself as a powershell or batch script but relies critically on the "-P --printpwd" commandline option when launching mc. Is this option implemented in windows version? If it is then I couldn't get it work; seemed to be ignored.

-P file, --printwd=file

Print the last working directory to the specified file.  This option
is not meant to be used directly.  Instead, it's used from a special
shell script that automatically changes the current directory of the
shell to the last directory Midnight Commander was in. Source the file
/usr/libexec/mc/mc.sh (bash and zsh users) or /usr/libexec/mc.csh
(tcsh users) respectively to define mc as an alias to the appropriate
shell script.

this was user error. mc will not overwrite --printwd=file so file must not exist.

here is a simple powershell equivalent of the mc_wrapper.sh scripts:

# mc-wrapper.ps1
#  powershell version of mc_wrapper.sh
# create alias for mc.exe as:
#  set-alias mc mc-wrapper.ps1
# mc-wrapper.ps1 assumes:
#  - it is on the path
#  - it is in the same dir as mc.exe

$ErrorActionPreference = 'Stop'
$mc_exe_dir =  "${PSScriptRoot}"
$mc_exe_path = "${mc_exe_dir}/mc.exe"

# get a random tmp file for mc --printwd 
# mc stores exit path in this file 
# make sure that it doesn't exist, mc will not overwrite
$mc_printwd_path = [System.IO.Path]::GetTempFileName()
Remove-Item "${mc_printwd_path}"

# run mc with --printwd and pass any additional cmdline args 
& "${mc_exe_path}" "--printwd=${mc_printwd_path}" "${args}"

# mc has exited, get mc_exitpath and cd 
try {
  $mc_exitpath = get-content -Path "${mc_printwd_path}"
  cd "${mc_exitpath}"
  remove-item -Force -Path "${mc_printwd_path}"
} catch {
  # catch everything prevents unecessary error msgs
  # some $args result in mc_printwd_path not being created 
  # e.g. -V, --help
}
