Code Editor

TrinovaQ Studio's code editor provides a professional, feature-rich editing experience purpose-built for automotive embedded software development. It supports both C and Rust source files and includes a curated library of automotive-specific code templates.

---

Language Support

The editor automatically detects whether you are working with C or Rust code and applies the appropriate:

• Syntax highlighting
• Auto-completion and IntelliSense
• Code formatting
• Static analysis markers

Language	File Extensions	Compiler
C	.c, .h	GCC (bundled)
Rust	.rs	rustc (system install required)

Language detection is instantaneous — no configuration required. Simply open a file and begin coding.

Editor Features

Tab Management

You can open multiple files simultaneously as tabs:

• Click a file in the Explorer panel to open it as a new tab
• Switch between open files by clicking their tabs
• Close a tab with the × button on the tab
• Tabs with unsaved changes are indicated with a dot (●) marker

Syntax Highlighting

Full syntax highlighting is provided for both C and Rust, including:

• Keywords, types, and operators
• String literals and comments
• Preprocessor directives (C)
• Macros and attributes (Rust)

Code Intelligence

The editor provides:

• Auto-completion: Context-aware suggestions as you type
• Bracket matching: Automatic highlight of matching brackets and braces
• Code folding: Collapse functions, structs, and blocks for better navigation
• Find and Replace: Ctrl+H opens the find/replace panel; Ctrl+F for find-only

Automotive Snippets Library

TrinovaQ Studio includes a curated library of code snippets for common automotive embedded patterns. Snippets reduce boilerplate and promote safe, standards-aligned coding practices.

Using Snippets

1. Place your cursor in the editor
2. Type the trigger word (listed below)
3. Press Tab to expand the snippet
4. Use Tab to navigate between editable fields within the snippet

Available Snippets

header_guard

Generates a standard include guard to prevent recursive header inclusion:

#ifndef MODULE_NAME_H
#define MODULE_NAME_H

/* Your declarations here */

#endif /* MODULE_NAME_H */

for_safe

A defensive loop with explicit bounds checking — recommended for safety-critical code:

uint32_t i;
for (i = 0U; i < SIZE; i++) {
    if (i >= SIZE) { break; } /* defensive bound */
    /* loop body */
}

fsm_secure

A secure Finite State Machine (FSM) skeleton with a defensive default case:

typedef enum {
    STATE_INIT,
    STATE_RUNNING,
    STATE_ERROR,
    STATE_SHUTDOWN
} AppState_t;

AppState_t current_state = STATE_INIT;

switch (current_state) {
    case STATE_INIT:     /* initialization logic */ break;
    case STATE_RUNNING:  /* main logic */           break;
    case STATE_ERROR:    /* error handling */       break;
    case STATE_SHUTDOWN: /* cleanup */              break;
    default:             /* defensive default */    break;
}

Viewing Static Analysis Results in the Editor

When you run a static analysis scan (Ctrl+Shift+I), the results are overlaid directly in the editor:

• Inline markers: Red or yellow underlines on problematic code
• Gutter icons: Warning/error icons in the line number gutter
• Hover tooltips: Hover over a marker to see the rule ID and description

This integration allows you to address issues without switching away from the editor.

---

Auto-Save

The editor supports automatic saving to prevent data loss:

• Enable or configure auto-save in Settings → Editor → Auto-Save
• The default auto-save delay is 3 seconds after the last keystroke
• A dot indicator in the tab shows unsaved changes
• You are warned before closing a tab or the application if unsaved changes exist

---

Theme Support

The editor inherits the application theme:

• Dark Theme (default): Optimized for extended development sessions
• Light Theme: Available via Settings → Appearance → Theme

The active theme applies consistently across the editor, sidebar, and panels.
