Using with vim substitute command: lines created are not scanned in future steps. Can they be?
by dedec0 from LinuxQuestions.org on (#5QYXW)
Task: make a file made with long lines be wrapped to a desired width.
Bad solution:
1. Set textwidth variable with the desired width
2. Visually select the whole file: ggVG
3. Do the command gq
This is a horrible solution because it will join consecutive lines that are already smaller that the wanted maximum width we set up in step 1.
Soso solution:
1. Do the command :%s_^\(.\{44\}\)\([^.]\)\(.\+\)_\1\r \2\3_ge
This is not a complete solution because it will split each line just one time, each time the command is run. So, if a line is longer than 2 times the wanted width, you will end up with a line with the wanted width, and the rest of it in a line below it. To have this line also splitted, we have to repeat the command. But if the lines of our first run of the command are 3 times longer than the wanted width, we will still have longer lines, in the end. So, we run the command again, and again, and again... recursively, until all lines are good.
Do you know a solution in Vim for this?
Example file given below, with very long lines, good to use with the example command. Each line contain numbers from 00 to 99, to easierly seeing the results of tests:
