A bunch of macros for supporting ANSI colours in C

Luma

Luma is just a bunch of macros written to make it easier to use/remember ANSI Escape Sequences.

Usage

It's pretty easy, just use them like you would use a "string". For example:

puts( EF_RED " This is red text " EF_END );
Will output "This is red text" to stdout in red color if ANSI escape sequences are supported on your terminal.

Note: One should always output ESC_END before terminating the program to make sure that the terminal is back to attributes.

List of escape sequences

These are complete escape sequences to use for formatting output.

There are 3 categories of supported escape sequences:

• Text Attributes ET
  for styling the text.

• Foreground Colors EF
  for changing font color.

• Background Colors EB
  for changing highlight color.

From Wikipedia/ANSI_escape_code

ET_BRIGHT/ET_BRIGHT_OFF Turn on/off Bright (increased intensity) or Bold

ET_FAINT/ET_FAINT_OFF Turn on/off Faint (decrease intensity)

ET_ITALIC/ET_ITALIC_OFF Turn on/off Italic

ET_UNDERLINE/ET_UNDERLINE_OFF Turn on/off Underline

ET_BLINK/ET_BLINK_OFF Turn on/off Blink

ET_REVERSE/ET_REVERSE_OFF Turn on/off Reverse (swap foreground and background)

ET_CROSSED/ET_CROSSED_OFF Turn on Strikethrough

EF_COLOR Turn on foreground color where
COLOR = { BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, DEFAULT }

EB_COLOR Turn on background color where
COLOR = { BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, DEFAULT }

Compatibility

Run esc_support after make to check your terminal's support for ANSI escape sequences.
