Ultisnips: Tab triggering not working

[raorm]

Hello,

I apologize in advance if this is a trivial issue. I have been trying to fix this for hours but I am a new user and not very good at this.
I have set my snippets but nothing happens when I type the trigger word and press tab. I have tried googling possible fixes and made changes to my .vimrc accordingly but nothing has seemed to work so far. Not sure what to do. Any help would be greatly appreciated.

Thank you
I have copied my .vimrc here

It seems you have another let g:UltiSnipsExpandTrigger="<c-e> in there?

[raorm]

I added that after reading some other threads about having this issue. Removing it does not work, and adding it did nothing.

Can you please provide a docker repo for investigation? See CONTRIBUTING.md#reproducing-bugs

Your problem is here:

~
let g:UltiSnipsSnippetsDir = "~/project/dotfiles/.vim/snips"
let g:UltiSnipsSnippetDirectories=["UltiSnips", "snips"]
~

The first line tells :UltiSnipsEdit to open files in ~/project/dotfiles/.vim/snips (which should better be written as $HOME . "/project/dotfiles/.vim/snips". The second line tells the engine to look for snippets in all directories in your runtimepath and there in directories called UltiSnips and snips.

Your problem is that ~/project/dotfiles/.vim is likely not in your rtp. Try deleting the line about g:UltiSnipsSnippetsDir and change the other to:

let g:UltiSnipsSnippetDirectories=[$HOME . "/project/dotfiles/.vim/snips"]

Also read up in the documentation about these two variables (:help UltiSnips-snippet-search-path).
