SWG String File Editor

A Visual Studio Code extension for viewing and editing Star Wars Galaxies .stf (String Table File) files in plain text format.

Features

• View Binary STF Files: Automatically converts binary .stf files to human-readable text format
• Edit in Plain Text: Edit localized strings in a convenient text format with syntax:
  • Section headers: [string_name]
  • Properties: id=, crc=, text=
• Save Back to Binary: Automatically converts your edits back to the binary STF format when you save
• Preserve File Structure: Maintains all IDs, CRCs, and string mappings from the original file

Usage

Opening STF Files

1. Automatic: Simply click on any .stf file in VS Code's file explorer
2. Command Palette: Press Ctrl+Shift+P (or Cmd+Shift+P on Mac), type "Open SWG String File", and select a file

Editing Format

The extension converts binary STF files to this text format:

# Star Wars Galaxies String Table File
# Next Unique ID: 123

[string_name_001]
id=0
crc=1234567
text=This is the localized text content

[another_string]
id=1
crc=7654321
text=Another piece of text with\\nnewlines supported

Editing Tips

• Section Names: Each string entry starts with [name] where name is the string identifier
• Escape Sequences: Use \\n for newlines, \\t for tabs, \\\\ for backslashes
• IDs and CRCs: Keep the id and crc values intact unless you know what you're doing
• Comments: Lines starting with # are comments and will be ignored when saving

Saving Changes

Simply use Ctrl+S (or Cmd+S on Mac) or File > Save. The extension will automatically convert your text edits back to the binary STF format.

Technical Details

STF File Format

The extension understands the Star Wars Galaxies String Table File format, which consists of:

• Magic Number: 0xDEADBEEF (4 bytes)
• Version: Currently supports versions 0 and 1 (1 byte)
• Next Unique ID: Used for generating new string IDs (4 bytes)
• String Entries: Each entry contains:
  • ID (4 bytes)
  • Source CRC (4 bytes)
  • Text length (4 bytes)
  • Unicode text (UTF-16LE, variable length)
• Name Map: Maps string IDs to their identifier names

Based on Official Source Code

This extension was built by analyzing the official SWG source code from the LocalizedStringTableReaderWriter implementation in the client tools repository.

Known Limitations

• Large STF files (>10,000 strings) may take a moment to load
