Ltex do not pick a file as dictionary

[cinghiopinghio]

Describe the bug
When defining dictionary.en-US = ":path/to/file", the words in the text file are not added to the word list.

Steps to reproduce

test config test.json:

{
    "dictionary": {
        "en-US": [
            "pluto",
            ":/path/to/test.txt"
        ]
    }
}

test dictionary test.txt:

pippo

run the code:

echo "This is pippo and pluto." | ltex-cli --client-configuration=test.json -

I get the output:

-:1:9: info: 'pippo': Possible spelling mistake found. [MORFOLOGIK_RULE_EN_US]
This is *pippo* and pluto.
        Use 'hippo'

Expected behavior
One would expect that the words listed in test.txt are not found as errors.

LTeX configuration

External files are not supported by ltex-ls, only by vscode-ltex/coc-ltex (“Setting Scopes & Files” is under “vscode-ltex / coc-ltex”, not “LT_EX LS”).

Thanks for the quick reply.

Indeed you are right. I get confused by the fact that this configuration appears also in the global configuration.
There is no mention to the fact that it may not work in ltex-ls.

There is a striped bar to the left of the text—when you hover it, it says that it's client-specific.

I guess it's a good idea to state this more prominently somewhere at the top.

I see, thanks anyway.
