colorize 1.0.4
A port of Ruby's colorize library to D.
To use this package, run the following command in your project's root directory:
Manual usage
Put the following dependency into your project's dependences section:
d-colorize
A partial port of Ruby's colorize library to D.
To put it simply, this is a simple helper for printing colored output to a terminal.
Installing
This package is registered in the dub registry as colorize.
Usage
import colorize : fg, color, cwriteln, cwritefln;
void main()
{
cwriteln("This is blue".color(fg.blue));
auto c = "red";
cwritefln("This is %s".color(c), c);
}
Supporting cross-platform color printing
Colorize exports functions for wrapping strings around ANSI color escape sequences. Simply printing these strings should work fine for any UNIX system. However, for "colorized" printing to work on Windows, it's necessary to use one of the exported helper printing functions, provided by p0nce, also in this module.
Colorizing output works by using the color
API described below and for Windows
compatibility, we provide functions which parse the escape sequences and call
appropriate system-level. On all platforms other than Windows, these functions
should work just as their std.stdio
counterparts.
These are:
cwrite
void cwrite(T...)(T args) if (!is(T[0] : File))
With an overloaded version for File output:
void cwrite(S...)(File f, S args)
cwritef
void cwritef(Char, T...)(in Char[] fmt, T args) if (!is(T[0] : File))
With an overloaded version for File output:
void cwritef(Char, A...)(File f, in Char[] fmt, A args)
cwriteln
void cwriteln(T...)(T args)
cwritefln
void cwritefln(Char, T...)(in Char[] fmt, T args)
Setting background, foreground and text modes:
string color(
const string str,
const fg c,
const bg b=bg.init,
const mode m=mode.init
) pure;
Wraps a string around color escape sequences.
Params
- str = The string to wrap with colors and modes
- c = The foreground color (see the fg enum type)
- b = The background color (see the bg enum type)
- m = The text mode (see the mode enum type)
Example
color("This is red over green blinking", fg.blue, bg.green, mode.blink)
Setting background colors:
string color(const string str, const bg b) pure; // alias to background
Wraps a string around a background color escape sequence.
Params
- str = The string to wrap with background color
b
- b = The background color (see the bg enum type)
Example
color("This has a blue background", bg.blue);
background("This has a red background", bg.red);
Setting text modes:
string color(const string str, const mode m) pure; // alias to `style`
Wraps a string around a text mode.
Params
- str = The string to wrap with style
m
- m = The text mode (see the mode enum type)
Example
color("This text is bold", mode.bold);
style("This text is blinking", mode.blink);
Coloring with strings:
string color(const string str, const string name) pure;
Wraps a string around the foreground color, background color or text style
represented by the color name
. Foreground colors are represented by their enum
key ("blue"
will be 34
, "red"
31
, and so on) and backgrounds/modes are
prefixed with either "bg_"
or "mode_"
(thus, "bg_black"
will be 40
,
"mode_bold"
1
and so on).
Example
color("This text is blue", "blue");
"This is red over blue, blinking"
.color("red")
.color("bg_blue")
.color("mode_blue");
Params
Available colors and modes
fg
enum type (Foreground colors)
Foreground text colors are available through the fg
enum. Currently available
colors are:
fg.init
(39)fg.black
(30)fg.red
(31)fg.green
(32)fg.yellow
(33)fg.blue
(34)fg.magenta
(35)fg.cyan
(36)fg.white
(37)fg.light_black
(90)fg.light_red
(91)fg.light_green
(92)fg.light_yellow
(93)fg.light_blue
(94)fg.light_magenta
(95)fg.light_cyan
(96)fg.light_white
(97)
bg
enum type (Background colors)
Background colors are available with the same names through the bg
enum. This
is because background colors come with an offset of 10 to their foreground
counterparts and we wanted to avoid calculating the offset at runtime.
mode
enum type (Text modes)
Text modes are available through the mode
enum. Currently available text modes
are:
mode.init
(0)mode.bold
(1)mode.underline
(4)mode.blink
(5)mode.swap
(7)mode.hide
(8)
