replacer

Replace text in files.

Requirements

Python 2.7 or Python 3.

Install with pip as usual.

Or, use the AUR on Arch Linux.

replacer [OPTIONS] PATTERN REPLACEMENT [FILES ...]

Note that internally, we'll call Python with:

re.sub(<PATTERN>, <REPLACEMENT>, line)

for each line of every regular file found in the current working directory.

This means you can use fancy backward references with \1

By default hidden files, and files matching build-*, .git, .svn, *.py[co], *.[oa] , *.back, *~ , *.so, *.a will be ignored
If FILES is given, replacement will be performed on the files given as argument.
You can also specify --file-filter to specify a pattern to match against the filenames. For instance, to replace in every .c file, use:
```
replacer spam eggs --file-filter '*.c'
```
You can create a backup for each modified file by using --backup

See

replacer --help

for a full list of options

First version was implemented in Bash in ctafconf.

Then it was rewritten in Python in this commit.
