Here are some useful scripts for CotEditor, a text editor for macOS. Some of them are inspired by text transformation commands in TextWrangler (another macOS text editor).
The scripts should be added to the CotEditor scripts folder. All scripts work on the entire document, though this can be changed easily by modifying the CotEditor directives in the scripts.
