## Feature Details

### Code Editing

- **Multi-tab editor** -- Work on multiple files simultaneously with closable tabs.
- **Syntax highlighting** -- Built-in Python highlighting with extensible plugin support for additional languages.
- **Auto-completion** -- Context-aware code suggestions powered by Jedi.
- **Line numbers** -- Displayed alongside the editor with current line highlighting.
- **Search & Replace** -- Search within the current file, across folders, or project-wide with regex and case-sensitive options. Runs in background threads for large projects.
- **Code Folding** -- Collapse and expand indented blocks (functions, classes, loops) from the gutter fold triangles or the keyboard. Folding is indentation-based and only toggles line visibility -- it never modifies the text, so saving always writes the complete file. Folds self-heal after edits: a fold whose header no longer exists simply reopens instead of hiding the wrong lines.
- **Bookmarks** -- Mark lines and jump between them with the keyboard, or click the gutter to toggle. Bookmarks are anchored to the text (via `QTextCursor`), so they follow their code when lines are inserted or removed above them instead of drifting.
- **Multiple Carets** -- `Ctrl+Shift+L` puts a caret at the end of every selected line, and `Alt`-click adds or removes one anywhere. Typing and Backspace then apply at all of them as a single undo step; `Esc` or a plain click returns to one caret.
- **Split View** (`Ctrl+Alt+\`) -- A second view of the same file, sharing one document: an edit in either side shows up in the other at once, while scrolling and the caret stay independent.
- **Minimap** (`Ctrl+Alt+M`) -- An overview of the whole file drawn as bars following each line's length and indentation, with a band marking what is on screen. Click or drag to jump. Large files are sampled rather than drawn line by line.
- **Snippets** -- Type a trigger word and press Tab to expand it, then Tab through the placeholders with each default value selected. Uses the usual `$1` / `${2:default}` / `$0` notation, so existing snippets drop straight into `snippets.json`; a missing or broken file falls back to the built-in Python set.
- **Test Panel** -- Run pytest from a dock panel and read the results, failures first, with the summary as the status line. Double-click a row to open that test, jumping to the failing line.
- **Language Server Support** -- Non-Python files complete through a language server over stdio (TypeScript, Rust, Go, C/C++, Lua, JSON and more, configurable per suffix), while Python keeps using jedi. A server that is not installed simply means no completions rather than an error.
- **Encoding & Line Endings** -- A file's encoding and line-ending style are detected when it opens and written back unchanged when it saves, so editing one line of a CRLF file no longer rewrites every line. Both can be changed from the File menu; changing the encoding re-reads an unmodified file so mojibake can be fixed in place, and never discards unsaved work.
- **Format on Save** -- Optionally run yapf when a file is saved, keeping the caret on its line. Source that cannot be parsed is left alone rather than blocking the save.
- **Indent Guides & Trailing Whitespace** -- A vertical guide at each indentation level and shading on stray end-of-line whitespace, both toggleable from the Style menu.
- **Lint Diagnostics** -- Findings from `ruff` are underlined in the editor and listed in a Problems dock panel (rule, message, line), with double-click to jump. The **buffer** is checked, not the file on disk, so unsaved edits are covered; the run happens on a worker thread after typing pauses, and a stale result from a superseded run is discarded. If `ruff` is not installed, or a run fails, the editor simply shows no diagnostics rather than reporting an error.
- **Git Change Markers** -- The gutter shows how the file differs from its last commit: a green bar for added lines, orange for modified, and a thin red line where lines were deleted. Jump between changes with `Ctrl+Alt+Down` / `Ctrl+Alt+Up`, revert the change under the caret back to its committed form with `Ctrl+Alt+Z` (one undo step), and open a side-by-side diff of the whole file against HEAD from the Git menu. `Ctrl+Alt+B` toggles inline blame, showing the commit, author and summary that last touched each line. The committed version is read on a background thread when the file opens, and the comparison itself is a pure in-memory diff, recomputed only after typing pauses -- so editing never waits on git. Files outside a repository, or not yet committed, simply show no markers.
- **Occurrence Highlighting** -- Placing the caret on an identifier highlights every other whole-word occurrence of it in the file. Keywords and single characters are ignored, and the scan is skipped on very large files to keep caret movement instant.
- **Line Operations** -- Delete the current line or selection (`Ctrl+Shift+D`), sort selected lines (`Ctrl+Alt+S`), join selected lines into one (`Ctrl+Shift+J`), and (from the Text menu) natural sort, remove duplicate lines, remove blank lines, reverse line order, or align lines on a delimiter (e.g. `=`). Each is a single undo step.
- **Duplicate** (`Ctrl+D`) -- Duplicates the selection when there is one (selecting the new copy), or the whole line when there isn't.
- **Case Conversion** (Text menu) -- Uppercase or lowercase the current selection, keeping it selected.
- **Smart Selection** -- Expand the selection outward through word → line → enclosing indented blocks → whole file (`Ctrl+Alt+Right`), and shrink it back (`Ctrl+Alt+Left`). Shrinking only retraces expansions, and a manual selection change resets the history.
- **Increment / Decrement Number** -- Bump the integer under the caret up or down (`Ctrl+Alt+Up` / `Ctrl+Alt+Down`), handling negative signs and growing widths.
- **Rename in File** (`F2`) -- Rename every whole-word occurrence of the identifier under the caret across the file as a single undo step. Word boundaries protect partial matches (renaming `val` never touches `value`).
- **Navigation History** -- Jump back and forward through your cursor-jump history like a browser (`Alt+Left` / `Alt+Right`). A jump records both where you came from and where you went, so "back" returns to where you started.
- **Document Outline** -- A dockable tree of the current file's classes, methods, functions and module variables (parsed with `ast`, so no code runs). Double-click to jump to a definition.
- **Variable Inspector** -- Inspect and debug variables during code execution.

### Navigation

- **Command Palette** (Ctrl+Shift+A) -- Fuzzy-search every menu command by name or menu path and run it without hunting through menus. Matches are ranked by word boundaries, consecutive characters and prefixes, and each row shows the command's own keyboard shortcut.
- **Quick Open / Go to File** (Ctrl+P) -- Fuzzy-search the project tree by file name *or* folder path. Indexing runs in a background thread, skipping VCS, cache, virtualenv and build directories along with binary file types. Typing `>` at the start switches the same picker into command mode.
- **Go to Symbol** (Ctrl+Shift+O) -- Jump to any class, function, method or module-level variable in the current Python file. Symbols are parsed with the standard library `ast` module, so no user code is ever executed, and a file that does not parse simply yields no symbols instead of erroring while you type.
- **TODO Panel** (Tab > Tools, or as a dock) -- Scans the project for `TODO`, `FIXME`, `HACK`, `XXX`, `BUG`, `NOTE` and `OPTIMIZE` comments across Python, C-like, HTML, SQL and other comment styles. Filter by tag and double-click a row to open that file at that line. Tags are only reported when they follow a comment marker, so ordinary strings are not misreported.

### Code Execution & Debugging

- **Run Python scripts** (F5) -- Execute the current file with real-time output streaming.
- **Debug mode** (F9) -- Launch the Python debugger for step-through debugging.
- **Shell commands** -- Execute arbitrary shell/terminal commands from within the editor.
- **Virtual environment detection** -- Automatically detects and activates Python virtual environments.
- **Process management** -- Stop individual or all running processes.
- **Error highlighting** -- Errors displayed in red in the output panel.

### Code Quality & Formatting

- **YAPF Python formatting** (Ctrl+Shift+Y) -- Automatically format Python code using Google style.
- **PEP8 checking** (Ctrl+Alt+P) -- Validate code against PEP8 style guidelines.
- **Ruff linting** -- Fast, comprehensive Python linting in a background thread.
- **JSON reformatting** (Ctrl+J) -- Pretty-print and validate JSON content.
- **Trim Trailing Whitespace** (Text menu) -- Strip trailing whitespace from every line as one undo step, preserving the caret position.
- **Convert Indentation** (Text menu) -- Convert leading indentation between tabs and spaces (using your indent size). Only leading whitespace is touched, so tabs and spaces inside strings are never altered.
- **Configurable indent width** -- Tab-indent, unindent and Enter auto-indent all honour the configured indent size (`Text > Indent Size`), and the indent width is auto-detected from a file's own content when it is opened.
- **Text transforms** (Text menu) -- Case conversion (upper / lower / swap / title), naming-style conversion (`snake_case` / `camelCase` / `PascalCase` / `kebab-case`), number-base conversion (hex / decimal / binary), and encode/decode helpers (Base64, URL, HTML entities, JSON string escaping). Decoders that fail leave the text untouched.
- **Statistics** (Text menu) -- Line, word and character counts for the whole document or the current selection.

### File Operations

- **Create, open, save** files with standard shortcuts (Ctrl+N, Ctrl+O, Ctrl+S).
- **Open folders** (Ctrl+K) -- Navigate project directory structures.
- **Auto-save** -- Automatic periodic file saving to prevent data loss.
- **Session restore** -- Reopens every file that was open at the last shutdown, not just the last one. Missing, duplicate and already-open files are skipped, the list is capped, and a corrupt or hand-edited settings file can never block startup. Disable by setting `restore_session` to `false` in `.jeditor/user_setting.json`.
- **Multi-encoding** -- Seamlessly handle UTF-8, GBK, Latin-1, and other encodings with automatic detection.
- **Recent files** -- Quick access to previously opened files.

### Git Integration

JEDITOR includes a full-featured Git client:

- **Branch management** -- List, switch, and checkout branches from the toolbar.
- **Commit history** -- View commit metadata (author, date, message) in a table view.
- **Side-by-side diff viewer** -- Color-highlighted code comparison with line numbers.
- **Multi-file diff** -- Compare changes across multiple files.
- **Staging** -- Stage and unstage individual file changes.
- **Audit logging** -- All Git operations are logged for tracking and compliance.

### AI Assistant

Integrated AI assistant powered by OpenAI and LangChain:

- **GPT-3.5 / GPT-4 support** -- Connect to OpenAI's language models.
- **Interactive chat widget** -- Conversational AI panel within the editor.
- **Configurable models** -- Set custom API keys, endpoints, model names, and system prompts.
- **Async messaging** -- Non-blocking AI interaction using a message queue.

### Console & REPL

- **Interactive console** -- Execute shell commands with history navigation (Up/Down arrows).
- **Jupyter/IPython console** -- In-process IPython kernel with rich output support.
- **Multi-shell support** -- Works with cmd, PowerShell, bash, and sh.
- **Working directory control** -- Set the execution directory independently.

### Embedded Browser

- **Built-in web browser** -- Browse the web without leaving the editor.
- **URL navigation** -- Address bar with integrated search.
- **In-page search** (Ctrl+F) -- Find text within web pages.
- **Standard navigation** -- Back, forward, reload, and stop controls.

## Plugin Development

Create plugins in the `jeditor_plugins/` directory within your working directory. JEDITOR supports three types of plugins:

### 1. Programming Language Plugin

Add syntax highlighting for a new language:

```python
from je_editor.plugins import register_programming_language

register_programming_language(
    suffix=".rs",
    syntax_words={"keywords": ["fn", "let", "mut", "struct", "impl", "enum"]},
    syntax_rules={"keyword_color": "#FF6600"}
)
```

### 2. Natural Language Plugin

Add a new UI translation:

```python
from je_editor.plugins import register_natural_language

register_natural_language(
    language_key="ja",
    display_name="Japanese",
    word_dict={"file": "ファイル", "edit": "編集", "run": "実行"}
)
```

### 3. Run Configuration Plugin

Define custom execution environments:

```python
from je_editor.plugins import register_plugin_run_config

register_plugin_run_config(
    name="Node.js",
    run_config={"command": "node", "suffix": ".js"}
)
```

For a comprehensive guide, see `PLUGIN_GUIDE.md`.
