ccat

ccat is a file printing tool (like 'cat') which uses Regular Expressions to enable syntax highlighting.

---

Features

• 11 colors out-of-the-box: Red, Blue, Green, Magenta, Cyan, Black, White, Yellow, Gray, Orange and Dark Blue.
• Support for defining custom colors via the ccat.colors file.
• Regex-color mappings are stored in configuration files.
• Uses the file extension to determine which configuration file to use.
• Highly extensible - to add a config file for an specific file type, name the file <extension>.conf.
• Support for printing line numbers with the -n flag.
• Statically linked Go binary - no runtime dependencies, config files are distributed along with the binary.
• Cross-platform

Installing

If you have the go command installed, run make after cloning the repository.

---

Getting Started

The config files are embedded within the binary. They will automatically be installed to the correct location (%APPDATA/ccat on Windows, ~/.config/ccat on UNIX) when the program is first run.

As written above, if provided a file with extension .example, the program will look for the config file named example.conf. If such a file doesn't exist, the file is printed out without any highlighting.

---

Config Files

The config files are written in YAML. Each line has the following syntax:

"<regex>": COLOR

Note that the regex must be enclosed in double quotes, and the color must be capitalized.

---

Custom Colors

To define a color of your own, create a file named ccat.colors in the config directory (mentioned above). The syntax of this file is the following:

COLOR: <red> <green> <blue>

Note that the color name must be capitalized (and shouldn't contain spaces). The RGB values must each be from 0 to 255.

TODO:

• Allow users to provide a config file in the command-line, overriding the extension-based config file.
• Provide releases.
