This is an update of the Localization wiki page for Processing 3.
We've put a huge amount of work into making it possible for Processing to run in multiple languages. It's been great to see all the help from the community, which has provided several new languages and continued to refine them. Join us and contribute!
If you'd like to help the community by adding a new language or improving an existing translation, there are two options:
You can build the code and modify the
processing/build/shared/lib/languagesto add or modify an existing language. When you have updates, submit a pull request with the updates.
If you're not comfortable with building from source, simply make a folder called
languagesinside your sketchbook. Then copy a
.propertiesfile from the
languagesfolder inside your Processing download, and edit away. You'll need to restart Processing to see the changes.
If you are translating to a new language, there are a couple of things you will need to setup first before it works.
- Copy the default translation at
xxis the Java code for your language (usually the ISO 639-1 code).
- Add your new language code to the
- Translate strings in the file you just copied (change only the text after the
- Rebuild the project and restart Processing to see the changes
To find missing strings in an existing translation, you can use this script.
Download it to the root of your Processing source code and make it executable:
curl https://gist.githubusercontent.com/federicobond/741d5c7df61191e13408/raw/d8862f2599fd26ba88833094548d4bd77a8f6b5f/missing.sh > missing.sh chmod +x ./missing.sh
If you call it like this:
It will show strings that are missing from the default English properties file (indented lines are those found in the .properties file but not in the codebase)
If you call it with a language code as an argument:
It will compare the keys for that language against the keys in the default language .properties file. Again, the behavior with regards to indented lines is similar: those lines appear in the corresponding language file but were removed from the default one.
You can get false positives occasionally from this tool, depending on how the actual code is split into lines. Be sure to check for usages in the source code before removing or renaming any obsolete key.
A few key bindings that cause trouble on local keyboards were moved to the language file. The syntax used for each of these comes from the KeyStroke documentation for Java 8.
Redo, Comment/Uncomment, Increase Indent, Decrease Indent (
Editor.java). Redo is also included because it has cross-platform differences between macOS, Windows, and Linux.
menu.edit.redo.keystroke.macos = shift meta pressed Z menu.edit.redo.keystroke.windows = meta pressed Y menu.edit.redo.keystroke.linux = shift ctrl pressed Z menu.edit.comment_uncomment.keystroke.macos = meta pressed SLASH menu.edit.comment_uncomment.keystroke.windows = ctrl pressed SLASH menu.edit.comment_uncomment.keystroke.linux = ctrl pressed SLASH menu.edit.increase_indent.keystroke.macosx = meta pressed CLOSE_BRACKET menu.edit.increase_indent.keystroke.windows = ctrl pressed CLOSE_BRACKET menu.edit.increase_indent.keystroke.linux = ctrl pressed CLOSE_BRACKET menu.edit.decrease_indent.keystroke.macos = meta pressed OPEN_BRACKET menu.edit.decrease_indent.keystroke.windows = ctrl pressed OPEN_BRACKET menu.edit.decrease_indent.keystroke.linux = ctrl pressed OPEN_BRACKET

Step, Step Into, and Step Out (

It's also possible to override these settings in
preferences.txt. Leave the platform part of each key name off the end, for instance, add this line to use ctrl-Y for Redo:
menu.edit.redo.keystroke = ctrl pressed Y
