Adding new dictionaries

The program comes with English (en_US) and French (fr_FR) spell-checking dictionaries already installed. You can manually add additional Hunspell dictionaries in the folder TeXmacs\share\hunspell. You can grab such dictionaries at several places :

The Lyx repository (a bit old)

Github sources for LibreOffice dictionaries

If you want to make and distribute a version with other dictionaries (and in particular that corresponding to your Locale) it is really easy : just run the fully automated build environment (direct download)

You can also enrich the list of dictionaries by editing the line

dicts="en_US"

in the PKGBUILD file. You can for instance change it to:

dicts="en_US de_DE es_AR"

to add German and Argentinian spanish dictionnaries.
