YAML Color schemes for Gnome Terminal

Script(s) for defining Gnome Terminal (or Roxterm) themes with a YAML file.

Builds on Anthony25's gnome-terminal-colors-solarized for solarized Gnome Terminal colours (the repository is added as a submodule of this repository).

This repository comes with two YAML-base themes: zenburn and ztevenburn. The zenburn theme is based on planbnet's gnome-terminal-zenburn.sh, while ztevenburn similar to Zenburn, but with more contrast (i.e. a darker background).

Requirements

Perl (5.14 or later)

The following modules should be part of the default Perl installation:

• File::Basename
• FindBin
• Getopt::Long
• Time::Piece

The following modules will probably need to be installed separately:

• Pod::Usage
• YAML
• Term::ReadKey

Initialisation

git clone git@github.com:sbakker/gnome-terminal-profile.git
git submodule init

Usage

See the POD documentation of parse_yaml_theme.pl

perldoc src/parse_yaml_theme.pl

src/parse_yaml_theme.pl --manual

Standalone usage

The install.sh script was copied from Anthony25's gnome-terminal-colors-solarized repository and modified to include the use of the YAML parser.

git submodule init
mkdir -p ./colors/my-color

# ... create a colors.yaml in ./colors/my-color

./install.sh

Using with gnome-terminal-colors-solarized

To use with Anthony25's gnome-terminal-colors-solarized repository:

Copy your YAML file to a new directory in the colors directory:

mkdir /path/to/gnome-terminal-colors-solarized/my-theme
cp my-theme.yaml /path/to/gnome-terminal-colors-solarized/my-theme/colors.yaml

Then, "compile" it to create the appropriate files:

src/parse_yaml_theme.pl /path/to/gnome-terminal-colors-solarized/my-theme/colors.yaml compile

Finally, use the install.sh script to install the colour theme.

cd /path/to/gnome-terminal-colors-solarized
./install.sh

Converting gnome-terminal-colors-solarized profiles

Any "classic" profiles can be converted to YAML with the convert_solarized.sh script.

$ ./convert_solarized.sh
converting gnome-terminal-colors-solarized/colors/dark
converting gnome-terminal-colors-solarized/colors/dark_alternative
converting gnome-terminal-colors-solarized/colors/light

Scripts

install.sh

Copy of Anthony25's gnome-terminal-colors-solarized's install.sh script with small modifications to load YAML-base color schemes.

convert_solarized.sh

Script to convert "classic" color scheme formats to YAML-based. Just point it to a directory with a "colors" sub-directory (and optionally specify a prefix to use for the YAML-based output directory) and the script will do the rest.

show_theme.sh

Can show classic and YAML-based color themes.

# Look in colors/ztevenburn/colors.yaml
./show_theme colors/ztevenburn/colors.yaml
./show_theme ztevenburn

# Looks in "classic" gnome-terminal-colors-solarized/colors/light
./show_theme gnome-terminal-colors-solarized/colors/light

src/parse_yaml_theme.pl

Parse a YAML-based theme.

$ src/parse_yaml_theme.pl ./colors/ztevenburn/colors.yaml
bd_color='#E3CEAB'
bg_color='#1C1C1C'
fg_color='#BABDB6'
palette=( '#1C1C1C' '#DD9393' '#7F9F7F' '#E3CEAB' '#DFAF8F' '#C693A4'
'#8CD0D3' '#BABDB6' '#3F3F3F' '#EEA3A3' '#9FCF9F' '#F3DEBB' '#EFBF9F'
'#D7A3B4' '#9CE0E3' '#DCDCCC' )

Also has a preview option with the show sub-command:

src/color_matrix

Show a matrix of the terminal colours. Example with the ztevenburn theme:

src/ramp_color

Only works well on a TrueColor terminal.

Given a start color, display a color ramp of increasingly lighter or darker colors, and a demonstration of these colors in a text string.

See perldoc src/ramp_color for more information.

src/terminal_colors

Modified clone of the XFree86 256colors.pl. Can print a 256 colour map as well as a list of all extended colors and their RGB values or a visually pleasing spectrum (the latter only for TrueColor terminals).

See perldoc src/terminal_colors for more information.

src/random_theme.pl

Fun stuff for generating a completely random colour theme. Script spits out a random YAML configuration.

To generate, use random_theme.pl and run parse_yaml_theme.pl to show the results:

shell$ src/random_theme.pl > wacko.yaml
shell$ src/parse_yaml_theme.pl wacko.yaml show

This will look something like:

Then, save the YAML file in a theme directory and install the theme:

shell$ mkdir -p colors/wacko
shell$ mv wacko.yaml colors/wacko/colors.yaml
shell$ ./install.sh -p Wacko -s wacko

The result will then be something like:

src/theme_to_yaml.pl

Create a YAML file from a "classic" theme (or display a "classic" theme).

Example:

$ src/theme_to_yaml.pl gnome-terminal-colors-solarized/colors/light

Output:

# YAML dump of gnome-terminal-colors-solarized/colors/light/
# Generated by theme_to_yaml.pl, 30-Nov-2017 16:12:29 +0100
