Terminal output SVG screenshot tool.

This tool is a non-interactive terminal emulator that executes a single command, renders its output in an internal virtual session, and exports a screenshot as an SVG file.

• Comprehensive ANSI style support:
  • Bold, dimmed (faint), italic, underlined, and strikethrough text.
  • Text with reversed background/foreground colors.
  • Full range of colors: basic 16 palette, 256 xterm palette, and 24-bit truecolor.
• Optional font embedding for enhanced customization.
• Dark and light mode compatibility.
• Extensive theme collection from iTerm2-Color-Schemes.
• Support for custom themes, refer to custom themes.
• Flexible configuration system, see configuration files.
• Customizable window styles, see custom window styles.

• Install using cargo

  cargo install --locked --git https://github.com/pamburus/termframe.git

• Install using scoop

  scoop bucket add pamburus https://github.com/pamburus/scoop-bucket.git
  scoop install termframe

• Download latest release from download page

• Run a command and save the output to an SVG file

  termframe -o hello.svg -- echo "Hello, World"

• Redirect output of a command to termframe

  echo "Hello, World" | termframe -o hello.svg

• Use auto-sizing to determine optimal dimensions based on command output

  # Auto-detect both width and height
  termframe --width auto --height auto -o output.svg -- command
  
  # Width between 80 and 120 columns, height auto-detected
  termframe -W 80..120 -H auto -o output.svg -- command
  
  # Width between 80 and 200 columns, step of 4, initial 120
  # Height auto-detected, initial 40
  termframe -W 80..200:4@120 -H @40 -o output.svg -- command

• Configuration files are automatically loaded if found in predefined platform-specific locations.

  OS	System-Wide Location	User Profile Location
  macOS	/etc/termframe/config.{yaml,toml,json}	~/.config/termframe/config.{yaml,toml,json}
  Linux	/etc/termframe/config.{yaml,toml,json}	~/.config/termframe/config.{yaml,toml,json}
  Windows	%PROGRAMDATA%\termframe\config.{yaml,toml,json}	%USERPROFILE%\AppData\Roaming\termframe\config.{yaml,toml,json}

• The path to the configuration file can be overridden using the TERMFRAME_CONFIG environment variable or the --config command-line option.

  The order in which the configuration files are searched and loaded is as follows:

  • The system-wide location.
  • The user profile location.
  • The location specified by the TERMFRAME_CONFIG environment variable (unless the --config option is used).
  • The locations specified by the --config option (can be specified multiple times).

  If a configuration file is found in multiple locations, the file in each subsequent location overrides only the parameters it contains.

  If TERMFRAME_CONFIG or --config specifies - or an empty string, all default locations and any locations specified by previous --config options are discarded. The search for the configuration file locations starts over.

  To disable loading of configuration files and use the built-in defaults, --config - can be used.

• All parameters in the configuration file are optional and can be omitted. In such cases, default values will be used.

• config.toml

The [terminal] section supports flexible dimension configuration with auto-sizing capabilities:

[terminal]
# Simple fixed dimensions
width = 80
height = 24

# Auto-detection
width = "auto"
height = "auto"

# Range constraints with auto-detection
width = { min = 80, max = 200 }
height = { min = 24, max = 60 }

# Step alignment (round to nearest multiple)
width = { min = 80, max = 200, step = 10 }

# Initial values (preferred size with fallback to auto-detection)
width = { initial = 120 }
height = { initial = 30 }

# Full specification with all options
width = { min = 80, max = 240, step = 4, initial = 180 }
height = { min = 24, max = 60, initial = 48 }

The initial value in dimension configuration:

• Serves as the initial/preferred size when no CLI override is provided
• Acts as a fallback when auto-detection fails or produces unreasonable results
• Gets clamped to min/max constraints if they are also specified
• Enables consistent sizing across different commands and environments if the commands scale their output based on terminal size

You can create custom themes by placing theme files in the themes subfolder of your configuration directory.

Create a themes folder in your configuration directory:

Theme files can be in TOML, YAML, or JSON format. Use the appropriate file extension (.toml, .yaml, .yml, or .json).

• Dual mode theme (supports both dark and light modes): assets/themes/One Double.toml
• Single mode theme (dark mode only): assets/themes/One Double Dark.toml

You can create custom window styles by placing window style files in the window-styles subfolder of your configuration directory.

Create a window-styles folder in your configuration directory:

Window style files can be in TOML, YAML, or JSON format. Use the appropriate file extension (.toml, .yaml, .yml, or .json).

• macOS style: assets/window-styles/macos.toml
• Compact style: assets/window-styles/compact.toml

• Many parameters that are defined in command-line arguments and configuration files can also be specified by environment variables.

• Environment variables
