Taglist installation and tips

SO post

Ctrl+] - go to definition
Ctrl+T - Jump back from the definition.
Ctrl+W Ctrl+] - Open the definition in a horizontal split

Add these lines in vimrc
map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>

Ctrl+\ - Open the definition in a new tab
Alt+] - Open the definition in a vertical split

After the tags are generated. You can use the following keys to tag into and tag out of functions:

Ctrl+Left MouseClick - Go to definition
Ctrl+Right MouseClick - Jump back from definition

Search and replace

simple search and you can use wild card with this. By default this is case sensitive

/SEARCH_WORD

search and replace with regex

simple example

%s/SEARCH_WORD/REPLACE_WORD/g

the last g tells Vim to replace all instances of a match. There are other options other than g that you can look up.

more complicated example

ref search the http protocol and domain from string and replace with only protocol & domain

http://academy.mises.org/courses/econgd/

Method 1:

:%s/\(https\?:\/\/.\{-}\/\).*/\1/gc

use \{-}. Each searched regex pattern is surrounded by \( and \) in this mode. \1 give you the first match, \2

Method 2:

\v(https?):\/\/(.{-})\/.*        <-- Search
:%s,,Protocol:\1 - Domain:\2,g    <-- Substitution

:%s,, tells vim to use the last search results for the replacement.

\v is a magical search with regex with non greedy wildcard and you don't need to escape the () for the regex search group.

Method 3:

:%s/\v^(https?)\://([^/]+)/.*$!/Protocol:\1 \t Domaine:\2/g

\v allows magical regex search again :)

replace the nth pattern match

:%s/\(\zsPATTERN.\{-}\)\{N}/REPLACE/

search current word under cursor

ref In normal mode, move the cursor to any word. Press * to search forwards for the next occurrence of that word, or press # to search backwards.

Using * (also , ) or # (also ) searches for the exact word at the cursor (searching for rain would not find rainbow).

Use g* or g# if you don't want to search for the exact word.
