The ccat command I created for Linux – written in Pascal – types files to screen like the cat command does, except it runs the files through a color filter. An example of the output for a small XML file and a small Pascal file is shown below.

In order to try out ccat you first need to do a:
git clone https://github.com/sith-ikjetil/ccat.git
Then you need to have the free pascal compiler installed in order to compile the application. You install it on Ubuntu like this:
sudo apt install fpc
Then you navigate to the ./ccat/src directory and run the build.sh build script. After the build is finished you have a ccat executable and you can put it in a bin folder that is part of your path. For example /usr/bin or ~/bin if you have your own bin directory in your home directory.
Next you must create a directory in your home folder called .ccat (~/.ccat). Copy all .ccrc files from source directory ./ccat/ccrc/ to this directory.
This is all you need to have files colorized with output. There are now a small number of supported file types with their own color configuration. These are: .arduino, .asm, .c (includes .c, .cpp and .h), .cs, .js, .json, .pascal, .perl, .sh, .text, .xml. If a file does not have a corresponding ccrc file it defaults to the .text color filter file. Also these color configuration files are not all completely finished. The .asm for example does not have all instructions or registers included among other things. It is all a work in progress.
You can override the ccat command with --syntax=<first name of ccrc filename>
if you need to specify the syntax it should use.
