convert txt file with mixed spaces/tabs to tabs only (where possible) [closed]
Ok, none of the given solutions satisfied me, so I coded it myself. :)
See here:
Depending on the source language, you could try out GNU indent. It can do a large number of things relating to the indentation of source code, though it might be more complex than you need.
For example, if I give the following program to indent -di0 <inputfile>
#include <stdio.h>int main(int argc, char **argv){ int i; int j; for (i = 0; i < 10; i++) { for (j = 0; j < 10; j++) { printf("x"); } }}It will replace it with:
#include <stdio.h>int main(int argc, char **argv){ int i; int j; for (i = 0; i < 10; i++) { for (j = 0; j < 10; j++) { printf("x"); } }}Or, if you need something stupid simple, there is the expand/unexpand commands.
You could use a regular expression to replace N spaces by a tab charater. For example in Python:
import rere.sub('[ ]{4}', '\t', text)
