Simple utility written in go that extends the standard fmt.Sprintf and fmt.Printf functions. It allows you to set foreground/background color, bold, underlined and italic text.


(1) Format

[Colorization]

Base format

${<target text>}(<fg>:<bg>)
  • <target text> is the text that will be colorized.

  • <fg> is the name of the foreground color (c.f. color list), or an hex color (e.g.#00ffaa, #0fa).

  • <bg> is the name of the background color with the same syntax as for the foreground.

Example
clifmt.Printf("normal text ${red text over black}(red:#000) normal text")

Note that it is not recommended to nest the different coloring formats.

Foreground only

${<target text>}(<fg>)
  • <target text> is the text that will be colorized.
  • <fg> is the name of the foreground color.
Example
clifmt.Printf("normal text ${red text}(red) normal text")

Background only

${<target text>}(:<bg>)
  • <target text> is the text that will be colorized.
  • <bg> is the name of the background color.
Example
clifmt.Printf("normal text ${text over red}(#ff0000) normal text")

[Markdown-like format]

Bold format

**<target text>**
  • <target text> is the text that will be bold.
Example
clifmt.Printf("normal text **bold text** normal text")

Italic format

*<target text>*
  • <target text> is the text that will be italic.
Example
clifmt.Printf("normal text *italic text* normal text")

Underline format

_<target text>_
  • <target text> is the text that will be underlined.
Example
clifmt.Printf("normal text _underline text_ normal text")
