Raffaello command-line output colorizer

Project description

Raffaello - output colorizer

Raffaello colorizes the output stream of any command-line tool (e.g. gcc/g++, cmake, dmesg, syslog and custom), making it easier to read.

Usage

The raffaello’s command line interface let you use two call modes: pipes and command.

In pipe mode you call raffaello like:

::

| raffaello [options]

In command mode raffaello will call your stream source in your behalf

::

raffaello [options] -c

To highlight the output stream, Raffaello has 2 color modes and 2 styles modes:

Color modes:

  • 8 colors mode let you use the following names: black, red, green, yellow, blue, magenta, cyan, light_gray. NEW Starting from version 3.0.3 Raffaello introduces a blind color: lines matching the pattern with color “blind” will be REMOVED from the stream. This will improve readability of dense stream output.

  • 256 colors mode let you use other 248 colors and choose between foreground or background colors (you can mix 8 colors mode names with 256 color mode names):

Color styles:

  • Foreground color names are in the form colorNUM. E.g. foreground red is color001
  • Background color names are in the form bgcolorNUM. E.g. background red is bgcolor001

With the styles you can blend colors in bold and underlined

  • foreground red bold is color001_bold
  • foreground red underlined is color001_underlined

Call raffaello -l to see the complete list of available colors.

   Usage: raffaello (-p PRESET | -r REQUEST | -f FILE | -l) [options]

       -p PRESET, --preset=PRESET              Prebuilt config files for coloring known output streams (gcc/g++, cmake, dmesg, gcc/g++, ModemManager, logcat...)
       -r REQUEST --request=REQUEST            The requested text/color mapping string. Multipe requests are separated by a space. Regular expression are supported. E.g. "error=>red [Ww]arning=>yellow_bold".
       -f FILE --file=FILE                     Path to the custom text=>color configuration file.
       -c COMMAND --command=COMMAND            Instead of using raffaello with pipes, set the command-line tool to be executed by raffaello directly. E.g. -c "dmesg -w".
       -m, --match-only                        Print only the lines that match against some defined pattern.
       -d DELIMITER --delimiter=DELIMITER      If you don't like "=>" as delimiter between text and color, use this flag to change it. E.g. -d & [default: =>]
       -l, --list                              List all the available colors and presets
       -v --verbose                            Enable debug logging

**NEWS** - version 3.0.3 –match-only flag Print only the lines that
match against any defined pattern.

Examples
--------

The simpler usage is using the ``request`` flag. The ``request`` flag
requires a string in the form “text=>color anothertext=>anothercolor”,
where text can be a constant string or a `Regular
expression <https://docs.python.org/2/library/re.html>`__, while color
is the name of the color to use (see `Usage <#Usage>`__ section)

-  Simple constant text highlight

   ::

        $ ifconfig eno1 | raffaello --request="collisions=>blue"

example001

-  Highlight of multiple texts. Here you can see that spaces in the
   “text part” are not allowed. Use :raw-latex:`\s `instead.

   ::

        $ ifconfig eno1 | raffaello --request="RX\spackets=>green TX\spackets=>red"

example002

-  Highlight with regular expressions

   ::

        $ ifconfig eno1 | raffaello --request="\d+\.\d+\.\d+\.\d+=>green_bold"

example003

For more complex color mapping you can write a file with a line for each
*text=>color* entry, like the following

::

   collisions=>blue
   RX\spackets=>green
   TX\spackets=>red
   \d+\.\d+\.\d+\.\d+=>green_bold

save the file and provide it to raffaello using its fullpath

::

   $ ifconfig eno1 | raffaello --file=$HOME/colorfile

example004

Color files can be reused in other color files using the ``include``
directive followed by the fullpath to the file.

Using fullpath is annoying, tough, so Raffaello has a special path under
$HOME/.raffaello. All the colorfiles inside this folder can be passed
using simply their filename, without the path.

::

   # include custom colorfile in $HOME/.raffaello
   include some_custom_colorfile

   # include custom color outside $HOME/.raffaello
   include $HOME/path/to/some_other_custom_color

   collisions=>blue
   RX\spackets=>green
   TX\spackets=>red
   \d+\.\d+\.\d+\.\d+=>green_bold

Raffaello provides some built-in colorfiles, called **presets**, for
known tools like cmake, gcc/g++, dmesg, etc. The presets can be used
alone using ``--preset`` flag or even included in custom colorfile in
order to extend their colormaps.

::

   # Include a preset colorfile
   include errors

   # include custom colorfile in $HOME/.raffaello
   include some_custom_colorfile

   # include custom color outside $HOME/.raffaello
   include $HOME/path/to/some_other_custom_color

   collisions=>blue
   RX\spackets=>green
   TX\spackets=>red
   \d+\.\d+\.\d+\.\d+=>green_bold

For a full list of presets, call ``raffaello --list``.

Raffaello is a python module
----------------------------

Raffaello can be used as a python module inside other source codes

.. code:: python

   from raffaello import Raffaello, Commission

   request = '''
   error=>red
   warning=>yellow_bold
   bluish\stext=>color026
   '''

   c = Commission(request)
   r = Raffaello(c.commission)

   print(r.paint('Sample message with error, warning and a bluish text.'))

::

   # python setup.py install

Install from `PyPI - the Python Package
Index <https://pypi.python.org/pypi>`__
