Changelog

All notable changes to this project will be documented in this file.

[1.0.2] - 2026-06-24

Added

• CFR Decompiler Integration: You can now decompile class files into Java source code directly within the editor.
• Live Java Compilation: Edit decompiled Java code and seamlessly compile it back into bytecode with Ctrl+S.
• Compiler Dependency Manager: Easily add extra .jar files to your compilation classpath via Project > Manage Dependencies.
• Multi-Tab Workspace: Introduced a Chrome-style tabbed editor allowing you to work on multiple class or resource files simultaneously without losing state.
• Java Syntax Highlighting: Added a full-fledged highlighting engine for Java syntax when in Java editing mode.
• Modern UI Theme: Completely modernized the user interface with the AtlantaFX PrimerDark theme for a sleek, developer-friendly experience.
• Auto-Scanning libs Folder: The compiler now automatically scans for a libs directory adjacent to your target JAR file to populate the classpath.
• Save Actions: Added Ctrl+S to compile/assemble the active tab, and Ctrl+Shift+S to save all modified tabs and execute a project export.

Changed

• The bytecode editing engine no longer restricts you to just .jasm. Users can seamlessly switch between .jasm assembly and full Java mode.
• The global details and constant pool views have been reworked to dynamically sync with the currently active tab.

Changelog

All notable changes to JarByteEditor are documented here.

1.0.1

Added

• Added JavaFX desktop GUI with dark theme, menu bar, toolbar, project tree, editor tabs, status bar, and responsive window scaling.
• Added syntax-highlighted .jasm editor for class bytecode using RichTextFX.
• Added grouped sidebar with root jar, classes, files, file-type icons, and sidebar search.
• Added Google Translate project workflow using the Google Translate web service on translate.google.com.vn, without a Cloud Translation API key.
• Added translation language selection, progress/log dialog, preview table, per-string checkboxes, and apply-selected behavior.
• Added CLI commands for listing, disassembling, assembling, replacing strings, searching, statistics, diff, and call graph.
• Added export workflow that writes raw classes, resources, .jasm files, and project.json.

Changed

• Replaced colored toolbar squares with matching vector icons.
• Improved editor colors for a softer dark UI and more readable bytecode tokens.
• Changed JAR opening to lazy-load entries instead of reading every file into memory immediately.
• Changed class rendering so .class files are only disassembled when the user selects a class.
• Changed translation scanning to process entries one by one and avoid caching untouched class bytes in memory.
• Changed project statistics/call graph behavior in the GUI to avoid automatic deep parsing after opening large jars.
• Changed Find and Replace workflows to run in background tasks so the GUI stays responsive.
• Changed Save As JAR to stream unchanged entries from the source jar when possible.

Fixed

• Fixed UI freezing risk when opening jars with many classes.
• Fixed large text/class preview by disabling unsafe inline editing and showing safe metadata/sample content.
• Fixed expensive SHA1 calculation for large lazy entries by deferring hash generation until needed.

Tests

• Added translation tests for resource and class string replacement.
• Added lazy-load tests to verify large entries are not loaded during open/save.
• Added lazy translation scan test to verify class scan does not cache untouched class bytes.
