===== Nemo Tips =====

==== executable Text Files ====

By default, Nemo asks whether to display or run executable text files. As all files on Windows Samba shares are executable, this can become annoying very quickly. To change this:
Edit -> Preferences -> Behaviour -> Executable Text Files -> View executable text files when they are opened

==== Nemo keyboard shortcuts ====

By default, there is no keyboard shortcut to move files/directories from one pane to another (when working with multiple panes by pressing ''F3''). A lot of other functions don't have keyboard shortcuts either.

The shortcuts are stored in ''~/.gnome2/accels/nemo''

Create the folder and edit this file:
<code>
mkdir -p ~/.gnome2/accels
vi ~/.gnome2/accels/nemo
</code>
 or search for "Move to next pane" when the file exists (or any other function you require. Remove the preceding semicolon and define the shortcut key. In this example, the shortcut will be set to ''CTRL+j'';
<code>
(gtk_accel_path "<Actions>/DirViewActions/Move to next pane" "<Primary>j")
</code>

Quit nemo from the command line using:
<code>
nemo -q
</code>

NOTE: Ensure not to use a shortcut already defined for something else!


==== Nemo Context Menus ====

Nemo supports custom context menus by simply creating a file in an 'actions' folder. Nemo does not need to be restarted to pick up any new or changed actions.

Global action scripts need to be placed in ''/usr/share/nemo/actions'' and user actions can be placed in ''~/.local/share/nemo/actions/''. File extension has to be ''.nemo_action''.

<code>cd ~/.local/share/nemo/actions/</code>

A full description of the syntax is available in the sample file ''/usr/share/nemo/actions/sample.nemo_action''

More examples can be found at https://wiki.archlinux.org/index.php/Nemo
The sample file is also here:\\
https://github.com/linuxmint/nemo/blob/master/files/usr/share/nemo/actions/sample.nemo_action

=== Mass renaming ===

<code>
sudo apt-get install gprename
</code>
<code - bulk-rename.nemo_action>
[Nemo Action]
Name=Bulk Rename
Comment=Multiple Rename with GPRename.  The action gets executed for the marked or the higher level directory.
Exec=gprename %F
Selection=m
Extensions=any;
EscapeSpaces=true
Dependencies=gprename;
</code>

=== Image convert / rotate ====

<code>
sudo apt-get install nemo-image-converter
</code>
Then restart nemo to activate the plugin. Right-click context menu entries for images will be available.

=== MP3 Tagging example scripts ===

<code - mp3-lyrics.nemo_action>
[Nemo Action]
Name=Add Lyrics to MP3s
Comment=Add Lyrics to MP3s
Exec=gnome-terminal -x sh -c "/home/wuff/getlyric/get_mp3_lyrics.py --sites genius.com --in_dir '%F' --write2tag"
Icon-Name=gtk-cdrom
Selection=s
Extensions=dir;
Quote=double
EscapeSpaces=true
</code>

<code - mp3-lyrics-2.nemo_action>
[Nemo Action]
Name=Add Lyrics to MP3s
Comment=Add Lyrics to MP3s
Exec=gnome-terminal -x sh -c "/home/wuff/getlyric/get_mp3_lyrics.py --sites genius.com --in_dir '%P' --write2tag"
Icon-Name=gtk-cdrom
Selection=none
Extensions=dir;
Quote=double
EscapeSpaces=true
</code>

<code - beets_import_album.nemo_action>
[Nemo Action]
Name=Import Album to Beets
Comment=Import Album to Beets
Exec=<beets_import_album.sh %F>
Icon-Name=gtk-cdrom
Selection=notnone
Extensions=dir;
#Quote=double
EscapeSpaces=true
Terminal=true
</code>
<code - beets_import_album.sh>
for var in "$@"
do
    folder=$(basename "$var")
    echo "Importing '$folder' into beets..."
    beet im "$var"
done
sleep 10
</code>
<code>
chmod 755 .local/share/nemo/actions/beets_import_album.sh
</code>

=== Copy Full Path to clipboard ===

<code - ~/.local/share/nemo/actions/copy_full_filepath.nemo_action>
[Nemo Action]
Name=Copy Full Filepath
Comment=Full Path: %F
Exec=sh -c "readlink -f %F | xclip -selection clipboard"
Icon-Name=gtk-copy
Selection=notnone
Extensions=dir;nodirs
Separator=,
Dependencies=readlink;xclip;
</code>

==== Nemo Performance ====

If opening folders with lots of images takes a long time, changes are a plugin is causing this:

disable the plugin "ChangeColorFolder+NemoPython" and restart nemo (nemo -q on command line) and start it again by opening any folder.

If opening folders with videos takes a long time, the thunbnailer for videos can be replaced with ffmpegthumbnailer which is faster (note that on updates of totem the config probably will be replaced):
<code>
sudo apt-get install ffmpegthumbnailer
cd /usr/share/thumbnailers/
sudo cp totem.thumbnailer totem.thumbnailer.original
sudo vi totem.thumbnailer

#replace line 2-3 with:
TryExec=/usr/bin/ffmpegthumbnailer
Exec=/usr/bin/ffmpegthumbnailer -s %s -i %i -o %o -c png -f

#exit nemo
nemo -q
</code>

==== Save/Restore session ====

Execute nemo_save.sh to save list of opened nemo windows in ~/.config/nemo/nemo.openwindows.

Launch nemo_restore.sh to reopen saved list of windows.

Restrictions : the script cannot save opened tabs, and won't save a folder whose name is too long. For special folders like Trash, you can replace the window title name in nemo_save.sh if you know the full path. Also, only the currently active pane in two-pane mode is being saved.

for dir in "${dirs[@]}"; do

#Add to current user's crontab

Auto-save on Cinnamon shutdown:
<code>
echo "session-cleanup-script = /home/$USER/.local/bin/nemo_save.sh" | sudo tee -a /etc/lightdm/lightdm.conf.d/70-linuxmint.conf

Restore session on Cinnamon start:
