belformat

Belformat is a simple and convenient tool for styling and formatting output in C. Use a syntax similar to HTML and add originality to your project. Belformat operates around the standard output functions in C from stdio.h, as well as ANSI escape codes.

The library is written in the C programming language and does not require additional dependencies to function. You can use this tool as either a statically generated library or as a dynamic library depending on your needs.

The project is open to everyone, and anyone familiar with CONTRIBUTING.md can suggest their own changes to the repository to make Belformat better and more convenient.

Examples

If you prefer not to read all the detailed examples of the library usage below, compile a single example file and run it by executing:

$ make examples
$ ./exam

Formatting

Belformat provides all the standard formatting methods available to ANSI users with a simpler and more understandable syntax.

Bold

Use the <b> tag (for bold) before the start of the text block you want to make bold, and close the tag with </> at the end f the block to reset all styles added before it.

</> is universal for every single tag, as it appends clear sequence that deletes all styling.

Italic

To achieve italic text, use the <i> tag (for italic) and close it with </> at the very end, resulting in a similar outcome:

Underlined

Underline text with the <u> tag (for underlined), which like all tags, must be closed with </> to remove its effect for all subsequent characters.

Strikethrough

To get strikethrough text, use the combination of <s> tag (for strikethrough) and </> as in previous cases.

Dim

Dim color is relative to the current text color and depends on your terminal settings. Use a combination of <d> tag (for dim) and </> to achieve the desired result.

Reversed

Reversed color swaps the text color and the background color. Use <r> (for reversed) along with </>.

Blinking

This type may not be available for your terminal. Wrap the text in <l> (for blinking) and close it with </>.

Private

You can hide the output values using <p> (for private) and close it with </>.

Styling

In addition to formatting using standard ANSI, you can also style text using terminal-dependent colors. Available colors are: black, red, green, blue, yellow, magenta, cyan and white.

The general syntax for adding colors works as follows: <tag_name;foreground_color;background_color>. For example:

To add color exclusively without formatting, use the <c> (for color) tag.

If you wish to have your own colors, you can add them with HEX color notation like so:

Utility

The project also has several utilities for logging output (bellog() function), information (belinfo() function), warnings (belwarn() function), and errors (belerror() function).

Compilation

Belformat assumes you have a C compiler (either GCC or clang) installed, as well as GNU make for building the library.

To generate a dynamic library, follow the instructions for your operating system below:

POSIX

$ make psx_belformat

Windows

$ make win_belformat

Otherwise, generate a static library with the following command:

$ make static_belformat
