Package ansiterm provides a Writer that writes out the ANSI escape codes for color and styles.
Color represents one of the standard 16 ANSI colors.
const ( Default Color Black Red Green Yellow Blue Magenta Cyan Gray DarkGray BrightRed BrightGreen BrightYellow BrightBlue BrightMagenta BrightCyan White )
String returns the name of the color.
Context provides a way to specify both foreground and background colors along with other styles and write text to a Writer with those colors and styles.
Background is a convenience function that creates a Context with the specified color as the background color.
Foreground is a convenience function that creates a Context with the specified color as the foreground color.
Styles is a convenience function that creates a Context with the specified styles set.
Fprint will set the sgr values of the writer to the specified foreground, background and styles, then formats using the default formats for its operands and writes to w. Spaces are added between operands when neither is a string. It returns the number of bytes written and any write error encountered.
Fprintf will set the sgr values of the writer to the specified foreground, background and styles, then write the formatted string, then reset the writer.
SetBackground sets the background to the specified color.
SetForeground sets the foreground to the specified color.
SetStyle replaces the styles with the new values.
const ( Bold Style Faint Italic Underline Reverse Strikethrough Conceal )
TabWriter is a filter that inserts padding around tab-delimited columns in its input to align them in the output.
It also setting of colors and styles over and above the standard tabwriter package.
NewTabWriter returns a writer that is able to set colors and styels. The ansi escape codes are stripped for width calculations.
Flush should be called after the last call to Write to ensure that any data buffered in the Writer is written to output. Any incomplete escape sequence at the end is considered complete for formatting purposes.
A Writer must be initialized with a call to Init. The first parameter (output) specifies the filter output. The remaining parameters control the formatting:
minwidth minimal cell width including any padding tabwidth width of tab characters (equivalent number of spaces) padding padding added to a cell before computing its width padchar ASCII char used for padding if padchar == '\t', the Writer will assume that the width of a '\t' in the formatted output is tabwidth, and cells are left-aligned independent of align_left (for correct-looking results, tabwidth must correspond to the tab width in the viewer displaying the result) flags formatting control
SetColumnAlignRight will mark a particular column as align right. This is reset on the next flush.
Writer allows colors and styles to be specified. If the io.Writer is not a terminal capable of color, all attempts to set colors or styles are no-ops.
NewWriter returns a Writer that allows the caller to specify colors and styles. If the io.Writer is not a terminal capable of color, all attempts to set colors or styles are no-ops.
ClearStyle clears the text style.
Reset returns the default foreground and background colors with no styles.
SetBackground sets the background color.
SetColorCapable forces the writer to either write the ANSI escape color if capable is true, or to not write them if capable is false.
SetForeground sets the foreground color.
SetStyle sets the text style.
