New translations and corrections to existing translations are welcome! See the Adding a Translation section. Here is the status of current translations:

• French ❌ needs full review
• Japanese ✅ by @AKKED
• Polish ✅ by @m1chu

Built with Electron. Uses node-exiftool as a wrapper for Exiftool binaries. To see the current list of NPM dependencies, run:

yarn list --production

Clone the repository and cd into the directory.

git clone https://github.com/szTheory/exifcleaner.git
cd exifcleaner

Next, install the NPM package dependencies.

yarn install

Pull down the latest ExifTool binaries:

yarn run update-exiftool

Finally, launch the application. This supports Hot Module Reload (HMR) so you will automatically see your changes every time you save a file.

yarn run dev

This app is mostly feature complete. I want to keep it simple and not add a bunch of bloat to it. And I want to avoid release churn. That said, there are a couple small features that might be worth adding. And there are a few minor bugs or points of cleanup that would be worth polishing. If you'd like to help check out the Issue Tracker which contains an exhaustive list of known issues. Just pick one and submit a Pull Request or leave a comment and I can provide guidance or help if you need it. Make sure to test the app out to see if it still works though. There isn't much going on in this app so it should be easy enough to do. I might add some automated tests later on to help with this. For now it's just been me working on the app so manual testing has worked out fine.

TypeScript code is formatted using Prettier.

Adding a translation is easy. All you have to do is go to the translation list, click on "Edit this file", and add an entry for the new language underneath the other ones. So for example if you wanted to add a Spanish translation, where it says:

"empty.title": {
  "en": "No files selected",
  "fr": "Aucun fichier sélectionné"
},

You just add a line for "es" (list of language codes here) underneath the other ones:

"empty.title": {
  "en": "No files selected",
  "fr": "Aucun fichier sélectionné",
  "es": "Spanish translation here"
},

and repeat that pattern for each of the entries. That's probably the easiest way to contribute. If you want to be able to see all of your translations working in a live app before submitting, you can also do this:

1. Fork the project on Github
2. Follow the directions here to get ExifCleaner running in development mode on your computer
3. Then update the strings.json file as mentioned above, and quit the program and relaunch it to see your changes. When you're finished, commit your changes from the command line with for example git commit -am "Finished adding translations". Then run git push origin master, and go to the project URL your forked it to (for example https://github.com/myusernamehere/exifcleaner) and click the button to open a new Pull Request.

If you want to run the app with a specific locale without changing your system preferences, use the following command. In this example ExifCleaner will start in Polish.

yarn run dev --lang=pl

Let me know if you run into any issues, I can guide you through the process if you get stuck.

This section is really for my own reference when publishing a new release.

Bump the version with release:

yarn run release

When the Github release page comes up, mark it as draft. Then run the publish command:

yarn run publish

Once you're happy with the release and want to finalize it, remove the draft flag on the Github releases page.

Thanks to all the people who submitted bug reports and fixes. I've tried to include everyone so if I've missed you it was by accident, just let me know and I'll add you.
