Bug description

This is a Regression, as those files worked before!

(nemo:175450): Nemo-WARNING **: 18:45:48.500: An action definition requires, at minimum, Name, Exec and Selection fields, and either an Extensions or Mimetypes field.
Check the /home/<user>/.local/share/nemo/actions/encode750kbs.nemo_action file for missing fields.

So .. NAME, EXEC, SELECTION and EXTENSIONS is the required minimum.

That's the file:

[Nemo Action]
Name=Encode to 750kb/s
Comment=Encode videofile to 750kb/s

Exec=gnome-terminal -x sh -c "encode750kbs.sh \"%F\""

Icon-Name=soundconverter

Selection=Any
Separator=;

#Extensions=mp4;
Extensions=m4a;mp4;avi;webm;ogg;ogv;mkv

Another nemo_action file with exact these fields works without an error:

[Nemo Action]
Name=Play 3D Video
Comment=Spiele Videos in 3D ab.

#Exec=echo "%F" >> /tmp/print.log
#Exec=gnome-terminal -x sh -c "echo %F | less"
Exec=<play3d.sh %F>


Icon-Name=soundconverter

Selection=Any
Separator=;

Extensions=m4a;mp4;avi;webm;ogg;ogv;oga;wav;mkv

Steps to reproduce

start nemo in debug mode

Expected behavior

acceptance or a detailed error message whats missing or is wrong.

Additional information

No response

as soon as i changed the Execline to a sperate script in the same directory and switched to Exec=<script %F>... nemo accepts it again :( That's a waste of files ;)

[Cyborgscode]

In case one needs to fix this:

$ cat encodexmbs.sh 
#!/bin/bash 

gnome-terminal -- sh encodexmbs.sh $1 "$2"

$ cat encode750kbs.nemo_action 
[Nemo Action]
Name=Encode to 750kb/s
Comment=Encode videofile to 750kb/s

Exec=<encodexmbs.sh 750 %F>


Icon-Name=soundconverter

Selection=Any
Separator=;

Extensions=m4a;mp4;avi;webm;ogg;ogv;mkv

You shouldn't need to specify gnome-terminal, try using Terminal=true. You might then get away with simply sh -c ...

It looks like there is an issue with backslashes in Exec.

I have the exact same bug. Here are my observations:

With Exec=sh -c "pdftotext %F - | xclip -selection clipboard", everything works fine.
With Exec=sh -c "pdftotext %F - | tr '\0-\11\14' ' ' | xclip -selection clipboard", I get An action definition requires, at minimum, Name, Exec and Selection fields, and either an Extensions or Mimetypes field.

Also:
🗴 Exec=sh -c "pdftotext %F - | tr \\0-\\11\\14 \ | xclip -selection clipboard" does not work.
🗸 Exec=sh -c "true | pdftotext %F - | xclip -selection clipboard" works.
🗸 Exec=sh -c "pdftotext %F - | tr '[:cntrl:]' ' ' | xclip -selection clipboard" works.
