Syntax error in binding {kb-mode-previous,kb-mode-next,select}: cannot have an empty modifier

[lonkaars]

Rofi 1.7.5 seems to not correctly parse empty keybindings on the command-line:

$ rofi -version
Version: 1.7.5
$ echo "" | rofi -no-config -dmenu -kb-mode-previous '' -kb-mode-next '' -p '>'

This command should open rofi without errors, but gives the following errors:

rofi-pass uses empty keysims to clear the shortcuts, but these currently cause issues with rofi. A workaround I found is to use a single comma (normally used to specify lists, see man rofi-keys(5)) instead of an empty string, which appears to fix the issue. After this fix rofi-pass works normally.

This does seem to be an issue with rofi itself, so I am unsure if this change should be implemented here. I'll open up an issue over there ASAP edit: https://github.com/davatorium/rofi/issues/1950.

This issue was caused by a custom wrapper that did not properly forward arguments, not rofi-pass or rofi.
