Purge Dark Mode

This repo contains a cli script written in go to remove all the dark: tailwind classes from all files within a directory.

Buy Why???

Alot of starter-kits and templates now comes with light and dark mode support with tailwind.

But I don't want both themes. It's overkill for most projects, and mainting both can be difficult. Getting 1 theme right is often a good strategy.

Recently built something with Laravel + React starter kit and ran into this issue. So made this to remove all dark classes in one swoop.

Technically we can leave both light and dark theme classes in and force one of em by setting a class at top level, but I didn't want unused classes littered throughout the codebase.

So this script is to remove all those pesky little dark: theme tailwind classes from your project.

If you wanted to only keep the dark themed classes and remove the light themed ones, it'd be easy to modify the script to do that as well. Although not something it supports right now.

How to use

1. Clone the repo
2. Run go build -o purge-dark-mode main.go
3. Run ./purge-dark-mode -dir=/path/to/your/directory ( The defaul is set to the currnet working directory, so be careful running it in this directory since there is a dark: in the go code that will be removed. )

Cli Flags

• -dir : The directory to search for files. Default is the current working directory.
• -dry-run : by setting this flag no actual changes will be made to the files. You can view the logs to make sure everything looks good before running the script without this flag.
• -log-level: Set the log level. Options are debug, info, warn, error. Default is info.

By default the gitignored files are ignored by reading the top level .gitignore file. Currently multiple .gitignore files are not supported. As of now there is no way to turn this off. The .git directory is also skipped by default.

Tip

You should git commit your changes before running the script. This way you can easily review the chagnes and revert them if something goes wrong.

TODO

• Support multiple .gitignore files in children directories.
• Ignore .css files. It's possible to have dark: string in css files, we should probably not touch those. So having a way in the cli to provide certain file extensions to ignore would be nice. As a workaround for now, before running the script those file extensions can be added to the .gitignore file and removed after running the script.
