Usage

Basic Syntax

text2file [COMMAND] [OPTIONS]

Available Commands

Examples

Generate a text file

# Short syntax
text2file "Hello, World!" txt

# Long syntax
text2file generate --content "Hello, World!" --extension txt

# Specify output directory and filename prefix
text2file generate --content "Hello, World!" --extension txt --output-dir ./output --prefix myfile

List all supported file formats

text2file list

Generate a video file

# Generate a basic video with text overlay
text2file generate --content "Sample video content" --extension mp4

# Generate a video with custom duration and resolution
text2file generate --content "Custom video" --extension mp4 --duration 10 --resolution 1280x720

This will create a video file with the specified content as text overlay. Video generation supports:

• Custom duration (in seconds)
• Custom resolution (e.g., 1920x1080)
• Background and text color customization

Advanced Image Generation

Generate a set of images from a JSON configuration

Create a JSON file (e.g., icons.json) with the following format:

{
  "icons": [
    {"src": "icon-16x16.png", "sizes": "16x16"},
    {"src": "icon-32x32.png", "sizes": "32x32"},
    {"src": "icon-64x64.png", "sizes": "64x64"}
  ]
}

Then run:

# Generate placeholder images with default text
text2file generate-set icons.json

# Use a base image and resize it
text2file generate-set icons.json --base-image source-icon.png

# Customize the placeholder appearance
text2file generate-set icons.json --text "My App" --background-color "#f0f0f0" --text-color "#333333"

# Generate SVG images with custom content
text2file generate --content "<svg><circle cx='50' cy='50' r='40' fill='blue'/></svg>" --extension svg

Options:

• -o, --output-dir: Output directory (default: current directory)
• -b, --base-image: Base image to use for resizing (optional)
• --bg, --background-color: Background color for placeholders (default: "#ffffff")
• -t, --text: Text to render on placeholder images
• --fg, --text-color: Text color for placeholders (default: "#000000")

Create a JSON file (e.g., icons.json) with the following format:

{
  "icons": [
    {"src": "icon-16x16.png", "sizes": "16x16"},
    {"src": "icon-32x32.png", "sizes": "32x32"},
    {"src": "icon-64x64.png", "sizes": "64x64"}
  ]
}

Then run:

# Generate placeholder images with default text
text2file generate-set icons.json

# Use a base image and resize it
text2file generate-set icons.json --base-image source-icon.png

# Customize the placeholder appearance
text2file generate-set icons.json --text "My App" --background-color "#f0f0f0" --text-color "#333333"

Options:

• -o, --output-dir: Output directory (default: current directory)
• -b, --base-image: Base image to use for resizing (optional)
• --bg, --background-color: Background color for placeholders (default: "#ffffff")
• -t, --text: Text to render on placeholder images
• --fg, --text-color: Text color for placeholders (default: "#000000")

Generate an Excel (.xlsx) file

Generate Excel spreadsheets with support for:

• Multiple worksheets
• Auto-adjusted column widths
• Custom sheet names
• CSV-like data input

# Basic usage with CSV-like content
content="Name,Age,City\nJohn,30,New York\nAlice,25,London"
text2file generate --content "$content" --extension xlsx

# Custom sheet name
text2file generate --content "$content" --extension xlsx --sheet-name "Users"

# Disable auto-adjust column widths
text2file generate --content "$content" --extension xlsx --no-auto-adjust

Options:

• --sheet-name: Custom worksheet name (default: "Sheet1")
• --no-auto-adjust: Disable auto-adjustment of column widths (enabled by default)

The input content should be in CSV format where:

• Rows are separated by newlines (\n)
• Cells within a row are separated by commas (,)
• The first row is treated as headers if present

Example with multiple data types:

content="Name,Age,Salary,HireDate\nJohn Doe,35,75000,2020-05-15\nJane Smith,28,85000,2021-03-22"
text2file generate --content "$content" --extension xlsx --sheet-name "Employees"

This will create an Excel file with properly formatted cells, including:

• Text alignment
• Number formatting
• Date recognition
• Auto-adjusted column widths

For more complex spreadsheets, you can generate the XLSX file programmatically using the Python API:

from text2file import generate_file

# Generate with custom options
generate_file(
    content="Product,Price,Stock\nLaptop,999,15\nMouse,25,100",
    extension="xlsx",
    output_dir="./reports",
    prefix="inventory",
    sheet_name="Products",
    auto_adjust=True
)

Basic Excel file from CSV-like content

content="Name,Age,City\nJohn,30,New York\nAlice,25,London" text2file generate --content "$content" --extension xlsx

With custom sheet name

text2file generate --content "$content" --extension xlsx --sheet_name "Employees"

Disable auto-adjusting column widths

text2file generate --content "$content" --extension xlsx --no-auto-adjust

### Generate multiple files with different formats
```bash
text2file generate --content "Sample content" --extension txt,md,html,xlsx --output-dir ./output

Validate generated files

text2file validate --path ./output --recursive --verbose

Clean up invalid files

text2file cleanup --path ./output --recursive --dry-run

File Format Examples

Text Files

Plain Text (.txt)

text2file generate --content "This is a plain text file" --extension txt

Markdown (.md)

content="# Sample Markdown\n\n- Item 1\n- Item 2\n- Item 3"
text2file generate --content "$content" --extension md

Code Files

Python (.py)

content="def hello_world():\n    print('Hello, World!')\n\nif __name__ == '__main__':\n    hello_world()"
text2file generate --content "$content" --extension py

JavaScript (.js)

content="function helloWorld() {\n  console.log('Hello, World!');\n}\n\nhelloWorld();"
text2file generate --content "$content" --extension js

Documents

PDF (.pdf)

text2file generate --content "This is a sample PDF document" --extension pdf

Word Document (.docx)

text2file generate --content "This is a sample Word document" --extension docx

Spreadsheets

Excel (.xlsx)

content="Name,Age,City\nJohn,30,New York\nAlice,25,London"
text2file generate --content "$content" --extension xlsx

Image Sets

Generate multiple images from a JSON configuration file. This is useful for creating icon sets or multiple resolutions of the same image.

JSON Configuration Format

Create a file (e.g., icons.json) with the following structure:

{
  "icons": [
    {
      "src": "icon-16x16.png",
      "sizes": "16x16"
    },
    {
      "src": "icon-32x32.png",
      "sizes": "32x32"
    },
    {
      "src": "subdir/icon-64x64.png",
      "sizes": "64x64"
    }
  ]
}

Each entry in the icons array should have:

• src: Output file path (relative to output directory)
• sizes: Dimensions in format "WIDTHxHEIGHT" (e.g., "32x32")

Usage Examples

# Generate placeholder images with default text
text2file generate-set icons.json

# Use a base image and resize it
text2file generate-set icons.json --base-image source-icon.png

# Customize the placeholder appearance
text2file generate-set icons.json --text "My App" --background-color "#f0f0f0" --text-color "#333333"

# Specify output directory
text2file generate-set icons.json --output-dir ./output

Options

• -o, --output-dir: Output directory (default: current directory)
• -b, --base-image: Base image to use for resizing (optional)
• --bg, --background-color: Background color for placeholders (default: "#ffffff")
• -t, --text: Text to render on placeholder images
• --fg, --text-color: Text color for placeholders (default: "#000000")

Single Images

JPEG (.jpg, .jpeg)

text2file generate --content "Sample image content" --extension jpg --width 800 --height 600

PNG (.png)

text2file generate --content "Sample image content" --extension png --width 800 --height 600

SVG Image (.svg)

text2file generate --content "Sample SVG" --extension svg
