Dot Configs

Like many others, I maintain my own dot-file repo: https://github.com/lastweek/dot-home. It helps me setup the terminal whenever I start using a new machine.

I’m a heavy terminal user. For whatever coding task (e.g., kernel, RDMA, FPGA, scala, C), I use terminal. I sometimes use terminal to write paper as well.

There are several important tools I rely on: zsh, git, neovim, and tmux. And I’m grateful for folks working on these tools and their plugins.

  • For zsh, I use oh-my-zsh.
  • For git, I use git alias.
  • For tmux, I use tpm. I used to cook status line myself, but I have switched to powerline.
  • For nvim, I use vundle. And I have several cooked keys.

VIM

I’m using several popular tools: NERD Tree, NERD commenter, GitGutter, and Tagbar.

I created the following mapped keys so that I could invoke them quite easily. Basically I press \ first, and then press t, or f, or g. 

map \l :TagbarToggle<Enter>    => to toggle tagbar list
map \f :NERDTreeToggle<CR>     => to toggle nerd file tree
map \g :GitGutterLineHighlightsToggle<Enter> :GitGutterSignsToggle<Enter>   => to highlight git difference

Besides, I have several extra syntax files, for C, ASM, scala, and verilog. I started this when I was hacking linux kernel. It has so many new awesome macros (e.g., BUG_ON, for_each_cpu) and I want to diffrentiate them from normal functions. So I added those after/syntax files.

Colorful Man Pages

This is one thing I highly recommend. It was always a pain reading man pages, not until I found this trick. We can, in fact, redirect man outputs into vim, which in turn can present the text in a colorway.

Add these to your shell dotconfig: 

vman() { man $* | col -b | vim -c 'set ft=man nomod nolist' -; }    
alias man="vman"

Git

For git, I’m using git alias and a tool call tig.

The git alias project has quite a lot shortcuts. Those are my most used ones: 

g s

g l
g ll
g lll

g d
g dc
g ds
