Error message in trie.lua

[kekscode]

Any idea what i do wrong here?

Error on startup:

Hmm. This is the first error I've seen, but the cause is predictable. You are using a dictionary that contains rather long words, aren't you?
I can solve the problem itself (using vim.json to serialize), but it slows me down somewhat.
Can you tell me what dictionary you are using?

Does 51c48f9 fix it?

Not quite, the error now reads:

Error in luv thread:
...vim/lazy/cmp-dictionary/lua/cmp_dictionary/dict/trie.lua:40: Cannot serialise, excessive nesting (1001)

...vim/lazy/cmp-dictionary/lua/cmp_dictionary/dict/trie.lua:43: bad argument #1 to 'decode' (string expected, got nil)

It worked before using #56 if that helps with the same dictionaries de and en. I added the wordnet stuff while migrating my config to v3 though, so it is not really comparable. I'll come back to your question about the dictionary data i use in a sec.

w=/usr/share/dict/words && wc $w && wc --max-line-length $w 
235976  235976 2493885 /usr/share/dict/words

127351  127351 1232855 /Users/<redacted>/en.dict

The dicts are unpacked using:

brew install aspell && brew install wordnet && aspell -d en dump master | aspell -l en expand >$HOME/en.dict && aspell -d de dump master | aspell -l de expand >$HOME/de.dict

Hmmm, there is supposed to be a single word with more than 500 bytes. Perhaps it is not compatible with the new format of the dictionary.

[uga-rosa]

I have checked the dictionary and understand. It's because of the change in dictionary specifications (:h cmp-dictionary-option-paths).
I only used newlines as word separators (to be able to use external commands like look, grep, etc.). If you replace all the white space in the dictionary with newlines, it should work.

aspell -d de dump master | aspell -l de expand | sed 's/\s\+/\n/g' > de.dict

[uga-rosa]

I fixed the Find dictionaries chapter of the documentation.

aspell -d de dump master | aspell -l de expand | sed 's/\s\+/\n/g' > de.dict

wow... you're awesome, it just works now!

Full config line for lazy's build parameter:

build = [[brew install aspell && brew install wordnet && aspell -d en dump master | aspell -l en expand | sed "s/\s\+/\n/g" >$HOME/en.dict && aspell -d de dump master | aspell -l de expand | sed "s/\s\+/\n/g" >$HOME/de.dict]],

The lua [[ and ]] are helpful to avoid issues with nesting and escape sequence interpretation.

[uga-rosa]

I'm glad it's fixed.

I'm facing the same issue though creating a new dict using aspell -d de dump master | aspell -l de expand | sed 's/\s\+/\n/g' > de.dict doesn't work for me :/

EDIT:

Nevermind, forgot to wrap my path with vim.fn.expand
