macroni 0.1.2

Macroni interpreter

Macroni

DSL for GUI automation with OCR, template matching, and screen interaction.

Installation

1. Install Python Dependencies

pip install macroni

Note that pytorch for CPU is installed by default. If your NVIDIA GPU supports CUDA, you will have to manually reinstall pytorch for GPU.

2. System Permissions

macOS: System Preferences → Security & Privacy → Accessibility

Grant permission to Terminal/Python to control your computer

3. VSCode Extension

For syntax highlighting, please add the extension to vscode: Macroni Language Support

4. Usage

Basic Command

Interactive

macroni

Execute file

macroni --file script.macroni

Note: the first time running will take time because pytorch is a massive library.

Debug Mode

Enable interactive debugging with breakpoints:

# Enable debug mode
macroni --file script.macroni --debug

# Set breakpoints at specific lines
macroni --file script.macroni --debug --breakpoints 10 --breakpoints 25

# Or use short flags
macroni -f script.macroni -d -b 10 -b 25

Debug Commands:

• n (next) - Execute next line
• c (continue) - Continue to next breakpoint
• p <var> (print) - Print variable value
• q (quit) - Exit debugger
• eval <expression> - Evaluate expression

OCR Text Search (Recommended)

Find and click text on screen without templates:

# Capture region once, reuse forever (cached)
region = @capture_region("login_area", false);

# Find text in region
results = @ocr_find_text(region, 0.8, "Login", 1.0);

if @len(results) > 0 {
    text, conf, bbox = results[0];
    x1, y1 = bbox[0];
    @mouse_move(x1, y1, 500, true);
    @left_click();
}

OCR Functions:

• @capture_region(key, overwrite) - Interactive region capture with caching
  • Hover top-left → Enter → bottom-right → Enter
  • Returns (x1, y1, x2, y2) tuple
• @ocr_find_text(region, min_conf, filter, upscale) - Find text via OCR
  • region: From @capture_region() or null for full screen
  • min_conf: 0.0-1.0 confidence threshold
  • filter: Text substring to search for (case-insensitive)
  • upscale: 1.0 = no scaling, 0.5 = faster, 2.0 = tiny text
  • Returns [(text, conf, [[x1,y1],[x2,y2],[x3,y3],[x4,y4]]), ...]

Template Matching (Alternative)

@set_template_dir("./templates");
x, y = @find_template("login_button");

if x != null {
    @mouse_move(x, y, 1000, true);
    @left_click();
}

Templates folder structure:

templates/
  └── login_button/
      ├── ex1.png
      └── ex2.png

Language Basics

# Variables & types
x = 10;
name = "test";
coords = (100, 200);
items = [1, 2, 3];

# Booleans
enabled = true;   # true = 1
disabled = false; # false = 0

# Destructuring
x, y = (100, 200);
text, conf, bbox = results[0];

# Control flow
if x > 10 {
    @print("yes");
} else {
    @print("no");
}

while x < 100 {
    x = x + 1;
}

# Functions
fn click_button(x, y) {
    @mouse_move(x, y, 500, true);
    @left_click();
}

Key Functions

Mouse/Keyboard:

• @mouse_move(x, y, speed, human_like)
• @left_click()
• @press_and_release(delay_ms, ...keys)

Screen:

• @get_coordinates(label, use_cache) - Interactive coordinate capture
• @get_pixel_at(x, y) - Returns (r, g, b)
• @check_pixel_color(x, y, radius, r, g, b, tolerance)

Timing:

• @wait(ms) or @wait(ms, random_range)
• @time()

Recording:

• @record(name, start_btn, stop_btn) - Record mouse/keyboard
• @playback(name, stop_btn) - Replay recording

Lists:

• @len(list), @append(list, item), @pop(list, index), @shuffle(list)

Cache Files

Auto-created in working directory:

• regions_cache.json - OCR regions
• coordinates_cache.json - Captured coordinates
• pixel_colors_cache.json - Captured colors
• recordings_cache.json - Recorded macros
