Comparing Changes

A Visual Studio Code extension that highlights changes in files by marking inserted lines with + and deleted lines with −. This extension is particularly useful for comparing file changes in a structured and syntax-highlighted way.

Features

• Syntax Highlighting: Provides syntax highlighting for .cfc files, marking inserted lines with + and deleted lines with −.
• Custom Grammar: Includes a TextMate grammar for .cfc files to tokenize and highlight changes.
• Language Configuration: Supports auto-closing pairs, surrounding pairs, and comment tokens for .cfc files.

How to Use

1. Install the Extension: Click button "Install" to download

2. Compare Files:

   • Use the provided Python script CompareFolder.py to generate .cfc files that highlight changes between two folders.
   • Run the script with the following command:

     python CompareFolder.py "original_folder" -mo "modified_folder" -o "output_folder"

   • Open the generated .cfc files in VS Code to view the highlighted changes.

3. Verify Syntax Highlighting:

   • Create or open a .cfc file in VS Code.
   • Ensure that inserted lines are highlighted with markup.inserted.cfc and deleted lines with markup.deleted.cfc.
