zenbu (全部)

|Sample Usage|

A setup-agnostic cascading theme engine. Uses Jinja2 for templates and YAML for variable definition.

The above gif was brought to you by wzb-utils_.



pip install zenbu

or just move zenbu.py to somewhere in your $PATH. If you do the latter, you must install the dependencies in the following section manually.

If you are running Arch Linux, you can also use the AUR package zenbu-git_ (AUR).

If you are running Gentoo:


layman -o https://raw.githubusercontent.com/azahi/ricerlay/master/overlay.xml -f -a ricerlay layman -s ricerlay emerge app-misc/zenbu


  • Python (2 or 3)

The below are Python libraries that should be installed via pip. Alternatively, if you did pip install zenbu, these should have been automatically installed.

  • argcomplete
  • colorlog
  • Jinja2
  • PyYAML
  • termcolor
  • watchdog

Tab completion


sudo activate-global-python-argcomplete

If you installed via pip, you may need to run the following before autocompletion works:


grep 'PYTHON_ARGCOMPLETE_OK' "$(which zenbu)" &>/dev/null || sudo sed -i "1a # PYTHON_ARGCOMPLETE_OK" "$(which zenbu)"

usage: zenbu [-h][-l] [-t TEMPLATE_DIR][-d DEST_DIR] [-s VAR_SET_DIR][-f FILTERS_FILE] [-i IGNORES_FILE][-e] [-w][--watch-command WATCH_COMMAND] [--watch-dirs WATCH_DIRS][--diff] [--dry]variable_files [variable_files ...]]

A Jinja2 + YAML based config templater.

Searches for an optional yaml file with a variable mapping in ~/.config/zenbu/defaults.yaml,

an optional python file with filters in (by default) ~/.config/zenbu/filters.py,

an optional yaml file with an ignore scalar of regexes in (by default) ~/.config/zenbu/ignores.yaml,

and uses the Jinja2 templates in (by default) ~/.config/zenbu/templates/

to render into your home directory (by default).

Additional variable files can be applied by supplying them as arguments, in order of application.

They can either be paths or, if located in (by default) ~/.config/zenbu/variable_sets/, extension-less filenames.

Environment variable support is available; simply run with the -e flag and put the name of the variable in Jinja2 brackets.

The default Jinja2 globals and filters are available.

Order of precedence is: last YAML variable defined > first YAML variable defined > environment variables.

Variables are shallowly resolved once. Thus, for example you may have the following in your defaults.yaml for convenience:

n_primary: "{{ colors[colors.primary].normal }}"

Autocomplete support available, but only for the default variable set directory.

A file watcher is available via the -w flag. Whenever a variable file in use, the filters file, the ignores file, or a template file changes, the templates are rendered if there are any differences. This can be overridden with a custom list of directories via the --watch-dirs flag.

Diffs between the current destination files and template renderings are available via the --diff flag.

positional arguments: variable_files additional variable files

optional arguments: -h, --help show this help message and exit -l list variable sets. -t TEMPLATE_DIR template directory. Default: /Users/echan/.config/zenbu/templates -d DEST_DIR destination directory. Default: /Users/echan -s VAR_SET_DIR variable set directory. Default: /Users/echan/.config/zenbu/variable_sets -f FILTERS_FILE filters file. Default: /Users/echan/.config/zenbu/filters.py -i IGNORES_FILE ignores file. Default: /Users/echan/.config/zenbu/ignores.yaml -e whether or not to use environment variables. Default: don't use environment variables -w start file watcher. --watch-command WATCH_COMMAND what to execute when a change occurs. Default: Nothing --watch-dirs WATCH_DIRS override what directories to watch, colon-separated. Default: Nothing --diff show diff between template renderings and current destination files --dry do a dry run

Zenbu in the wild


What happened to whizkers?

This project may seem awfully similar to whizkers_; in fact, this is a fork of whizkers which swaps the Mustache backend out with Jinja2. I'm keeping whizkers around for compatibility reasons. So what are the reasons for switching?

  • Comprehensive documentation: See the Jinja2 Template Designer Documentation_.
  • Better logic: Everything from if/else to macros. I originally praised Mustache for its logic-less philosophy, but then I realized that there would be no place to put logic other than the variable sets, which is a nightmare.
  • Expressions: You can now do {{ ':bold' if use_bold else '' }}. You can even do {{ colors[colors.primary]['normal'] }}, which has led to the deprecation of the {` ... `} eval syntax.
  • Filters: You can now do {{ colors.black.bold | to_rgb }}. A lot better than Mustache's syntax.
  • Better whitespace control: This means increased readability.

To help ease the transition to zenbu, there are some tips under the migration wiki page_.
