gedit highlight misspelled words for every document by default

Question

Every time I open documents and for every new documents I have to re-enable the spell-checker in gedit.

How can I toggle it to always be on for every document?

Answer 1

No it can not be set as default.

That does not rule out that someone who knows how to decompile, reprogram and recompile the spell checker plugin for gedit can't make a setting for it, it is open source.

@NIMISHAN: Enchant is a dictionary, and is not responsible for spell checking, nor part of any program. Programs can use it. Even the spell checker in gedit is not part of gedit, just a plugin, plugged into gedit.

Answer 2

This is possible in gedit as of 3.38.2:

Got to Preferences -> Plugins -> Spellchecker -> Preferences and tick "Highlight Missepelled words".
