How can I create my own spelling file for vim?

Question

At the moment I'm writing a document where I need to use a lot of acronyms, technical language, and non German words.

Now I was wondering if I could create a spelling file (tech_speak) which checks for this technical language so I can use the following vim command

:set spelllang=de,tech_speak spell

How could this be done?

Solution 1

The 'spellfile' option is what you're looking for:

:set spellfile=~/.vim/spell/techspeak.utf-8.add

^{Note: Avoid special characters like _; as it separates the region name in Vim.}

You can then add your custom words to it with zg. You don't even need to add anything to 'spelllang'; those additions will be considered automatically.

Solution 2

:help spell-mkspell

is what you are looking for.

Please correct me if I'm wrong. But as far as I had read this I need an existing dictionary file. But I want to make a new language file which I can combine with my language.

Yeah this looks good but, when I use zg vim throws "E751: Output file name must not have region name" at me.

Ah I needed to remove the _ so :set spellfile=~/.vim/spell/techspeak.utf-8.add works. Thanks!

A dictionary file can be a simple word list.

You're right; it's best to avoid such characters; I've edited my answer.

@n.m. So like a csv? Just words separated by commas?
