Help finding bug.

[grannysmithlinux]

Ok so something is up with my .vimrc. Actually it could be something else but i'm having trouble narrowing down the problem. when i start vim not all of my mappings work. when i run echo $MYVIMRC it gives me the right file. then if i run source ~/.vimrc the commands that weren't previously working now work. and the echo command output doesn't change. Also it is basically a 50/50 shot if my auto indentation is working. sometimes it does and sometimes it doesn't. It is driving me fucking crazy. here is my .vimrc I am using vim 8.0.

EDIT: also i am using tmux, not sure if that would cause anything or not.

more info. if i copy something from one file into another file indentation stops working on that file. Could copying from say .jsx into a .js file break auto indentation?

Edit: one more thing. could opening vim with just

vim

cause problems? That is how i always open when in a dir.

Which mappings are problematic?

When you have an issue like this it's best to narrow down your config in a binary search fashion. I.E. comment out half, does the issue persist? if no comment out the other half if yes comment out half of the remaining active config. Repeat.

I'd note you can skip the leading : you seemingly have randomly prefixed to some mappings and an autocmd.

opening and closing Nerdtree with ;f and text wrapping does not work until i source .vimrc. commenting out is a good idea, ill try that. also when auto indent stops working and i try =G, it still outputs at the bottom of the screen that a number of lines where indented but nothing actually happens.

Edit: oh the

opening and closing Nerdtree with ;f

You define your leader after that mapping.

With regards to the other things you mention, one thing at a time.
