structured-config-previewer

Structured Config and Reg File Viewer is a desktop hierarchical configuration tree explorer,
syntax and duplicate-key validator, in-place key-value editor, and multi-format converter
for Linux developers and system administrators.
An independent Linux alternative inspired by desktop registry export and configuration
preview utilities, it parses, validates, edits, and converts .reg registry export files,
.ini and .conf files, systemd .service and .timer units, Freedesktop .desktop entries,
.toml documents, and .json configurations in a unified workspace.

Key Features:
- Hierarchical Tree Explorer & Reg File Parser: Parses REGEDIT4 and Version 5.00 .reg
exports (automatic UTF-16LE byte-order mark and UTF-8 detection, string, dword, qword,
hex binary, expandable string, and multi-string values) alongside INI, systemd unit,
Desktop Entry, TOML, and JSON hierarchies.
- Syntax & Duplicate-Key Validator: Pinpoints malformed lines, unclosed sections, invalid
typed values, duplicate sections, and duplicate keys across .reg, .ini, .conf, .toml,
and .json files with click-to-jump line navigation.
- Live In-Place Editing & Syntax Highlighting: Edits, adds, or deletes typed keys directly
in the tree inspector while keeping the syntax-highlighted text buffer synchronized.
- Bidirectional Format Conversion: Converts structured configuration trees cleanly between
.reg (UTF-16LE or UTF-8), .ini, and .json formats with live side-by-side preview.
