Changing spellcheck for Github Atom editor

By looking at the source of the spellchecking plugin, we can see it relied on Hunspell dictionaries.

Let's find all the interesting occurrences of hunspell:

~/.atom/.node-gyp/.atom/.apm/spellchecker/0.9.0/package/vendor/hunspell
~/.atom/.node-gyp/.atom/.apm/spellchecker/0.9.0/package/vendor/hunspell_dictionaries
/usr/local/share/atom/resources/app/node_modules/spell-check/node_modules/spellchecker/src/spellchecker_hunspell.cc
/usr/local/share/atom/resources/app/node_modules/spell-check/node_modules/spellchecker/vendor/hunspell_dictionaries

Now, let's find other dictionaries installed: find / 2>/dev/null | grep ".aff$"
You might get interesting stuff in those directories:

/usr/share/hunspell/[LANGUAGE-SPECIFIC].aff
/usr/share/ispell/[LANGUAGE-SPECIFIC].aff
/usr/share/myspell/dicts/[LANGUAGE-SPECIFIC].aff
/opt/libreoffice4.1/share/extensions/dict-[LANGUAGE-SPECIFIC]/[LANGUAGE-SPECIFIC].aff
~/.mozilla/firefox/[RANDOM-STUFF]/extensions/[LANGUAGE-SPECIFIC]@dictionaries.addons.mozilla.org/dictionaries/
~/.config/libreoffice/3/user/extensions/tmp/extensions/[RANDOM-STUFF].tmp_/[LANGUAGE-SPECIFIC-PLUGIN].oxt/dictionaries/

And now, instead of editing /usr/local/share/atom/resources/app/node_modules/spell-check/node_modules/spellchecker/src/spellchecker_hunspell.cc, backup those files :

/usr/local/share/atom/resources/app/node_modules/spell-check/node_modules/spellchecker/vendor/hunspell_dictionaries/en_US.aff
/usr/local/share/atom/resources/app/node_modules/spell-check/node_modules/spellchecker/vendor/hunspell_dictionaries/en_US.dic

And replace them with some other dictionary. I took the following files, renamed in order to overwrite the two above:

/opt/libreoffice4.1/share/extensions/dict-fr/fr.aff
/opt/libreoffice4.1/share/extensions/dict-fr/fr.dic

Initially, I thought that tweaking ~/.atom/.node-gyp/.atom/.apm/spellchecker/0.9.0/package/vendor/hunspell_dictionaries would do the trick, but actually no.

Not perfect, but better than nothing!
