Text
Utility functions to manipulate text with or without ANSI escape sequences. Most
of the functions available are used in one or more of the other packages here.
- Align text horizontally or vertically
- Colorize text
- Cursor Movement
- Format text (convert case)
- String Manipulation (Pad, RepeatAndTrim, RuneCount, Trim, etc.)
- Transform text (UnixTime to human-readable-time, pretty-JSON, etc.)
- Wrap text
The unit-tests for each of the above show how these can be used. There GoDoc
should also have examples for all the available functions.
