How to write a plugin and where to reference

  • Reference to popular plugins
  • Go to /usr/share/vim and find autoload, syntax, ftplugin (etc) system sample

Make command and errorFormat

  • Make command can be bound with different program like gcc, javac, gradle
  • Reference to github project: vim-gradle
  • ErrorFormat is used to parse the build command output and present to user at quickfix window
  • :compiler gradlew and then :make {gradle-task}
  • Famous plugins CtrlP takes advantage of the make system in vim and bind it with execute find and map output to errorFormat.

Search for files

  • :help find
  • Amazing when use with :set wildmenu
  • :find *.md and Tab

Use python in vim

  • :echo has("python")
  • :python print("hello world")
  • :pyfile mypython.py
  • In python script, there is a vim module to be used: 
    import vim
window = vim.current.window
window.height =200
window.width = 10
window.cursor = (1,1)

Register

  • Its about clipboard history.

Session

  • Session is the working status you are having with the file.
  • :mksession to save
  • Similarly, :mkview to save view

Tag

  • To create tag list, we can use ctag (most popular), vtags etc.
  • Let vim know where is the tag file and it will be able to navigate
  • Plugin tagbar can present.

Use abbrev to insert code snippet

  • iabbrev <buffer> for( for (x=0;x<var;x++){<cr><cr>}

Use Autocmd to insert template

  • autocmd BufNewFile *.html 0r $VIMHOME/templates/html.tpl
  • autocmd BufNewFile * silent! 0r $VIMHOME/templates/%:e.tpl

Map

  • map :NERDTreeToogle
  • map dd
  • imap : insert mode mapping
  • nmap : normal mode
  • noremap : no recursive mapping
  • nnoremap : normal mode noremap
  • See details with :help :map-commands

Search file by content

  • :vimgrep /import/ ** search all
  • :vimgrep /import/g ** search all. result inlcude a line for each match. And will jump to result.
  • :vimgrep /import/j ** search all. Silent search. Use clist to check.
  • :vimgrep /import/ *.md
  • :vimgrep /import/ **/*.md
  • :clist
  • :cnext

  • Let is used to set custom fields
  • System-defined fields (aka options) types:
    • Toggle option (aka boolean field)
    • Number option (aka int field)
    • String option (aka string field)
  • :set all - show all set options
  • :set number - turn on boolean field
  • :set number? - query field
  • :set number! - toogle boolean field
  • :set tabwidth=4 - set non boolean field
