MacroManager for jEdit: Top Tips and Best PracticesMacroManager is a jEdit plugin designed to help users create, organize, and run macros more efficiently. Whether you’re automating repetitive edits, customizing workflows, or sharing handy scripts across projects, MacroManager can turn a collection of ad-hoc snippets into a reliable toolkit. This article covers practical tips, best practices, and real-world examples to help you get the most out of MacroManager.
Why use MacroManager?
- Centralized macro storage: Keep all your macros in one place rather than scattered across files.
- Quick access: Bind frequently used macros to keyboard shortcuts or menus.
- Improved organization: Group related macros into folders or categories for faster discovery.
- Shareability: Export and import macro sets to share with teammates or across machines.
Getting started
- Install MacroManager from jEdit’s plugin manager (Plugins → Plugin Manager → Install).
- Open the MacroManager window (Plugins → MacroManager → Show MacroManager).
- Create a new macro with the + icon or import existing macro files (.bsh, .js, .py, etc.).
- Assign names, descriptions, and categories to make them easy to find.
Tip 1 — Choose the right scripting language
jEdit supports multiple scripting languages for macros (BeanShell, Jython, JavaScript, etc.). Choose based on:
- Existing knowledge: Use a language you already know to prototype quickly.
- API availability: Some languages have better access to Java classes used by jEdit.
- Performance needs: BeanShell can be lightweight for small scripts; Jython may be preferable if you need Python libraries.
Example:
- Use BeanShell for short text-manipulation macros that call jEdit’s API directly.
- Use Jython when you want to leverage Python’s libraries or read complex data formats.
Tip 2 — Name and document every macro
Good naming and documentation pay off. For each macro:
- Use descriptive names (e.g., “Convert Tabs to Spaces — 4 cols”).
- Add a short description explaining input assumptions and effects.
- Include usage examples and expected results in the description field.
This helps when you return months later or share macros with others.
Tip 3 — Organize with categories and folders
Group macros by purpose:
- Text formatting (e.g., wrap, indent, case conversion)
- Project tasks (e.g., update version numbers)
- Language-specific helpers (e.g., Java getters/setters)
- Utilities (e.g., file header insertion)
MacroManager supports folders — use them to mirror your typical workflow (e.g., “HTML”, “Python”, “Git-related”).
Tip 4 — Use keyboard shortcuts and menu integration
Assign shortcuts to your most-used macros:
- Go to Utilities → Global Options → Shortcuts (or use MacroManager’s keybinding feature).
- Avoid conflicts with common editor shortcuts.
- For infrequently used macros, add them to a menu or toolbar instead of binding keys.
Example: bind “Wrap long lines to 80 chars” to Ctrl+Alt+W.
Tip 5 — Keep macros idempotent and safe
Design macros so they can be run multiple times without causing unintended side effects:
- Check for existing states (e.g., if header already present, don’t add it again).
- Work on the current selection or buffer copies when possible.
- Provide clear error messages and fail gracefully.
This reduces surprises and makes macros predictable.
Tip 6 — Use parameters and prompts
Make macros flexible by prompting for input or reading arguments:
- Ask the user for values (e.g., search/replace strings, number of spaces).
- Allow applying to the selection, current line, or entire buffer.
- Use sensible defaults to speed up common cases.
Example: macro that asks for a delimiter and splits the selected line into multiple lines.
Tip 7 — Version control your macros
Store macro files in a git repository:
- Keep history of changes and allow reverting.
- Share via dotfiles or plugin-specific repositories.
- Use branches for experimentation before merging stable macros into your main set.
Example repo structure:
- macros/
- text/
- project/
- utils/
Tip 8 — Test macros with sample files
Before running macros on important files:
- Test on small sample files or copies.
- Create unit-style tests where possible (scripts that assert expected outcomes).
- Automate testing for complex macros using scripted checks.
This prevents accidental data loss.
Tip 9 — Reuse and modularize common code
If multiple macros share logic (e.g., parsing headers, reading config):
- Put shared functions into a common script file and source/import it.
- Keep utility functions small and well-documented.
- Avoid duplicating code across macros.
This simplifies maintenance and reduces bugs.
Tip 10 — Share and learn from the community
Look for macro collections and examples from the jEdit community:
- jEdit mailing lists and forums often have useful macros.
- Inspect bundled macros in jEdit for idiomatic usage.
- Share your polished macros with clear README and examples.
Example macros (short descriptions)
- “Insert File Header” — prompts for author, license, and inserts a formatted header.
- “Convert Indentation” — convert tabs to spaces or vice versa with a configurable tab width.
- “Wrap Selection to N Columns” — reflow selected text to a specified column width.
- “Toggle Comment Block” — comment/uncomment selection for multiple languages.
- “Batch Rename Files” — use regex-based rules to rename files in a project folder.
Troubleshooting common issues
- Macro not running: check scripting language availability and plugin errors window.
- Permission errors: ensure jEdit has file system access for scripts that read/write files.
- Conflicting keybindings: resolve via Global Options → Shortcuts.
Final best practices checklist
- Use clear names and descriptions.
- Organize macros into folders and categories.
- Assign shortcuts judiciously.
- Keep macros idempotent and test them.
- Version-control shared macros.
- Reuse common utilities, and document everything.
MacroManager turns small automation scripts into a dependable part of your jEdit workflow. With good organization, testing, and community sharing, your macro library will grow into a powerful productivity asset.
