Renaming

[AndreLaranjeira]

Some of the names employed by macros, functions, structs or enumerations are not satisfactory enough. However, since renaming them would be a breaking change, it should be done on a major release. And since I don't want to publish lots of major releases, I'll group all the renames into this issue in order to publish a single new major release (hopefully I won't change my mind afterwards about some name or triffle).

Note: Check stash. Some changes were made in advance and stashed.

Renaming list:

• Macro: TIME_FMT_SIZE -> ??? (Current name is not informative enough);
• Struct: DisplayColors.text_color -> DisplayColors.foreground_color (Better name that follows official ANSI documentation);
  • Function: color_text -> color_foreground (Same as main change);
  • Function: reset_text_color -> reset_foreground_colors (Same as main change);
