VIM Configuration

I am using the VIM editor while writing small codes. If you are using VIM as well, the following syntax highlighting and compiler output configurations might be useful. If you do not use the VIM editor, skip this.

Syntax Highlighting

grb256.vim This file contains some color labels to be used in the syntax files. Save this file to ~./vim/colors.

cSyntaxAfter.vim This file contains some syntax highlighting options for C based languages such as C/++ and java. Save this file to ~/.vim/plugin.

asm.vim This file contains some basic highlighting for assembling in the intel syntax in NASM. Save this file to ~./vim/after/syntax.

Syntastic

Syntastic is the plugin which highlightens compiler errors on save within the VIM editor. This helps alot for debugging and saves the trouble to manually run the compiler after each edit just to look for compiler errors. The following steps are taken from the readme.markdown file in vim-syntastic@github.

Step 1: Install pathogen.vim

Run the following command in the CLI

mkdir -p ~/.vim/autoload ~/.vim/bundle && \
curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim

Step 2: Install syntastic as a Pathogen bundle

You now have pathogen installed and can put syntastic into ~/.vim/bundle like this:

cd ~/.vim/bundle && \
git clone --depth=1 https://github.com/vim-syntastic/syntastic.git

Quit vim and start it back up to reload it, then type:

:Helptags

If you get an error when you do this, then you probably didn't install [Pathogen][pathogen] right. Go back to Step 1 and make sure you did the following:

1. Created both the ~/.vim/autoload and ~/.vim/bundle directories.
2. Added the execute pathogen#infect() line to your ~/.vimrc file
3. Did the git clone of syntastic inside ~/.vim/bundle
4. Have permissions to access all of these directories.

Enable NASM Checker

Now we will enable NASM to be used as the checker for .asm files. To do so, I have just copied the syntax checker in ~/.vim/bundle/syntastic/syntax_checkers/nasm edited it to the resulting nasm.vim below.

nasm.vim This file is the .asm syntax checker for Syntastic. Save this file into ~/.vim/bundle/syntastic/syntax_checkers/asm/.

vimrc Configuration

Now open the .vimrc config file with the following command:

$ vim ~/.vimrc

Then add the following lines to the file:

execute pathogen#infect()

colorscheme grb256
autocmd! FileType c,cpp,php call CSyntaxAfter()

set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*

let g:syntastic_always_populate_loc_list = 1
let g:syntastic_auto_loc_list = 1
let g:syntastic_check_on_open = 0
let g:syntastic_check_on_wq = 0

let g:syntastic_c_checkers = ['gcc']
let g:syntastic_asm_checkers = ['nasm']
