vim mappings – easy way to do things.

You can use vim mappings to make some of your editor tasks very simple. Here I am giving you just a example, but you could always let your imagination run wild.

:nmap ,b Oj0c$**hP

And what do we do here.

O – Add a new line

– Go to normal mode

j – go to newly added line

0 – Go to begining of line

c$ – Change till end of line

****<Esc> РEnter  four stars

h – go back one character.

P –¬† Paste the last deleted line, which is what we deleted with c$.

This is just to show you how powerful, mappings can be. So, GO WILD with imagination.

vim – yank/xopy in different register to paste

Very quick update, to use registers, you can select and then yank in a register to paste using the same register. This could be a convinient way to copy multiple selections and then paste which ever selection you want. Here is the simple way to do it:

visuallly select with v/V

then “qy to yank (here we are yanking into register q, so in the command you can use any of a-z to use as register)

then “qp to paste..

To, view all the registers, you can use the command “registers”.

Check all vim colorschemes for minor issues

Here is script that checks all the colorschemes in the current directory and corrects them if possible (Processing of the file is done with simple commands like sed, grep)

Checks that the color_name is same as Filename

Here is the script:

#!/bin/bash -
#          FILE:
#         USAGE: ./
#       OPTIONS: ---
#          BUGS: ---
#         NOTES: ---
#        AUTHOR: Amit Agarwal (aka), 
#      REVISION:  ---
cd ~/.vim/colors
for i in *vim
    #echo "Processing $i"
    if [[ $(grep -c g:colors_name $i ) -eq 0 ]]; then
        if [[ $(grep -c colors_name $i ) -eq 0 ]]; then
            echo "File $i does not have colorname";
            missing=$missing" $i"
            sed -i.bak '/colors_name/ s/.*/let g:colors_name="'${i//.vim}'"/g' $i
        if [[ $(grep -c colors_name $i|grep let ) -gt 1 ]]; then
            echo "WARN ----->> File $i has more than one colorsname"
        colorname=$(grep g:colors_name $i|grep let| sed -e 's/"//g' -e 's/.*=//' |tr -d ' ')
        if [[ ${colorname}.vim != $i ]]; then
            echo "Filename $i does not match colorname $colorname .. correcting "
            sed -i.bak '/colors_name/ s/.*/let g:colors_name="'${i//.vim}'"/g' $i
            #sed -i.bak 's/(.*g:colors_name.*=)/1'${i//.vim}'/g' $i

if [[ x$missing != x ]] ; then
    echo "Missing colornames in $missing"
