cfmt

cfmt

ANSI colours and basic movement.

Functions

Print()

Print() takes special fmt-style parameters in the form of keywords to style text/backgrounds and move the cursor.

Example:

	cfmt.Print("%blue %bgwhite Blue%normal\tNormal\n")

Note that keywords may be followed by a space when followed by letters. This extra space won't be printed.

Printf()

Printf() takes the keywords from Print and applies its styling, then parses it through fmt.Printf().

	cfmt.Printf("%red%t%normal\n", false)

Format()

Returns a formatted string directly, allowing you to further process it.

Example:

	s := cfmt.Format("%green Green")

TermSize()

This utility function returns the width and height of the current terminal in number of characters:

	w,h,err := cfmt.TermSize()
	…

Pos()

This function sets the position in the terminal window to print from. Best combined with %cls.
