Custom dictionary?

[SiddharthShyniben]

It would be great if we could manage a custom dictionary of common words we use, like abbreviations or names.

We should be able to, say, put a list of comma-seperated words in a file and have spelunker ignore those words.

How's using g:spelunker_white_list_for_user?

The command readfile() loads a file as a list of each lines.
Giving it to g:spelunker_white_list_for_user will work.

To write full script, like below:

" If not defined the list, initialize.
if !exists('g:spelunker_white_list_for_user')
    let g:spelunker_white_list_for_user = []
endif

" Load dictionary file.
" In the dictionary file, write keywords line by line.
let g:spelunker_white_list_for_user += readfile('SOME_DICTIONARY_FILE')

" Set all the keywords into lowercase.
call map(g:spelunker_white_list_for_user, { _, val -> tolower(val) })

" Remove duplicated keywords.
call unique(sort(g:spelunker_white_list_for_user))
