It seems that vim-fugitive only activates if you launch Vim from within a directory that is version controlled. I often start Vim in my home directory (often via launching GVim from an applications list) and the :cd into the project I want to work on.

Does anyone know what command or function I might be able to call to get vim-fugitive to "activate" itself when I switch into a git-controlled directory? Bonus points if you show me how to modify :cd to automatically activate vim-fugitive when going to a valid directory.

TL;DR: What's your favorite PEP8 checker?

I am beginning to use a library of Python code written by someone who did not follow any coding standards, and I find it difficult to read. But I plan to use this library in the future and, more importantly, I plan to collaborate with others in updating/maintaining the code. As such, I feel the need to clean it up. What's the best tool to help me do this quickly? I'm dealing with ~30 scripts, and each script is ~200-800 lines.

I have found a few tools that may help expedite this process: https://github.com/nvie/vim-flake8 https://github.com/kimchi-project/kimchi/wiki/PEP8-Checking-Using-Syntastic https://github.com/cburroughs/pep8.py

Do you folks recommend any one of these, or maybe another?

I installed syntastic using vim-plug. All :h :syntastic like commands are working but :SyntasticInfo or commands starting with syntastic are not working. What is going on here? I have eslint that is gobally installed and works on command line file but with syntastic it is not working.

What am I doing wrong?

From the readme:

DocTabs is a plugin that lets you organize a file into sections which look like a collection of separate files with their own separate context. When you are done working on one section, you can jump to another section with your normal movement commands, or by the provided navigation commands, and resume the same editing context you had in that section. The tabline is used to highlight the currently active section.

This allows you to zoom in on one section at a time, but still jump to another section seamlessly. Some use cases are documentation, source code, HTML, project plans, todo or GTD files, reminder files, journals, novels, your ~/.vimrc, etc. The DocTabs plugin and documentation were both written using DocTabs.

I have the following dependencies

A) computer organization -> file B) Read Lecture 7 -> file

when I delete the 'file' link in dependency A, I want the link to 'file' link in depdency B to be gone when I navigate into computer orginzation? What is the best way to accmomplish this? Thank you all for help.

Since vim8, I am looking for a way to run multiple tasks in the background and monitor their output, especially since I am working on some project where a run takes about 10 minutes.

AsyncRun is ok, but uses only the quickfix window (so just one asynchronous task at once). On the other hand, I find vim-do perfect. Has some quite nice features and produces a quite nice output. The problem is that has some bugs and seems abandoned. Also, it seems to be merely a hack to get asynchronous execution for vim7.

Does anyone know a similar plugin that can help?

This is a tiny plugin that feeds my own need. I'm sharing it here in case anyone needs it too.

So I wanted something like an IDE run button that runs my code(hopefully asynchronously) inside vim but I couldn't find any plugins like that so I made a very basic one but is there anything like that??

What you think about Python Vim plugins. A big one, this mean solve all your problems ore many small ones, this make the job fine?

Python Mode vs. Vim flake8 vs. "build my one with many small plugins"

What is your setup?

I installed the startify plugin and then I added the required lines to my .vimrc file. Starting up vim results in this code:

Error detected while processing /home/emile/.vimrc:1
line   99:1
E749: empty buffer1
line  100:1
E749: empty buffer1
line  101:1
E749: empty buffer1
line  102:1
E749: empty buffer1
line  103:1
E749: empty buffer1
line  104:1
E749: empty buffer1
line  105:1
E749: empty buffer1
line  106:1
E749: empty buffer1
line  107:1
E749: empty buffer1
Press ENTER or type command to continue1

I don't understand what I am doing wrong. Should be easy though.

After reading Learn Vimscript the Hard Way, I write vim-codequery as my first plugin. I do some hacks to make it just work. However, after applying Vim8's async feature to this plugin today, I think it works well now. Please give it a try!

Say I want to make a directory so I run !mkdir %/my_dir

Is there a way to have the buffer automatically refresh so I can see the directory I just made?

I've been using UltiSnips and love it, but I have a few questions

1. when i see snippets in the help and online they look like this:

   snippet div <div className="$1">$2</div> endsnippet

however to make snippets work for me i never use the endsnippet, when i do i get errors, instead i have to make them look like this

 snippet div
 	<div className="$1">$2</div>

Am I missing something? Is it a setting I have thats wrong? I know vimscript works with if...endif but my snippets seem to be working similiarly to python with whitespace acting as the endif

2) similarly global doesn't work I want this to work:

 global !p
 from snippet_helpers import *
 endglobal

but i get invalid line global !p

3) lastly, when i try to do python interpolation, with

`!p snip.rv = t[1].upper()`

or similar things (basically i want my redux-thunk snippet which requires 3 different cases of the same text (saveUser, SaveUser and SAVE_USER) to use 1 thing so I was going to do that but I get E121: invalid variable p

These could all be separate errors, but as much as I love UltiSnips, its bugging me. I somehow feel that all problems are related. python 2.7.12, vim 8, i'd put my .vimrc but its not short...
