Add option to replace the original file with -f flag

[marcinkrzeminski]

Hi,

with your code adjustments and a little bit of research, I was able to implement the -f, --force flag. By providing this flag as a first argument you can now replace the original file.

Feel free to refactor my code if it's crap ;). Like I said before I'm not a Python dev.

Examples:

Single file

crunch -f file.png

Directory recursive

find. -name "*.png" | xargs crunch -f

Tested on macOS Catalina, Version: 10.15.1 (19B88)

Thank you very much!! I will have a look and try to add tests this week so that we can get this merged. I really appreciate it!

I pushed these changes to the dev branch Marcin. Thank you very much for this work. I made some very minor edits to your source contribution in 02b5e45.

I still need to add new tests for the inplace file write functionality before we merge this to master. I am also thinking through how we might include this in the GUI and macOS services. Perhaps through a config file? Let's see.

I'd like to examine a handful of upstream changes that have happened in zopfli since our last release. I may try to roll that into a release that includes your new force/inplace overwrite support here.

Thanks again! We'll get this out soon!

Thanks for letting me know :).

As of GUI, I'd suggest a checkbox if possible. Config file seems a bit cumbersome, especially for less experienced users which are more likely to use the GUI version, instead of the command line.

Absolutely agree. This will require a full rewrite of the GUI application. It is just an automated wrapper around the Python script at the moment and I don't have a way to implement the settings configuration. Looking into this.
