cprint

• Wrap color print terminal log

The behavior is similar to print, the difference is that this interface also supports color terminal output, and supports emoji character output.

E.g:

    cprint('${bright}hello xmake')
    cprint('${red}hello xmake')
    cprint('${bright green}hello ${clear}xmake')
    cprint('${blue onyellow underline}hello xmake${clear}')
    cprint('${red}hello ${magenta}xmake')
    cprint('${cyan}hello ${dim yellow}xmake')

The results are as follows:

The color-related descriptions are placed in ${ }, and you can set several different properties at the same time, for example:

    ${bright red underline onyellow}

Indicates: highlighted red, background yellow, and with a down line

All of these descriptions will affect the entire entire line of characters. If you only want to display partial color text, you can insert ${clear} at the end position to clear the previous color description.

E.g:

    ${red}hello ${clear}xmake

In this case, only hello is displayed in red, and the others are still normal black display.

Other colors belong to, I will not introduce them here, directly paste the list of attributes in the xmake code:

    colors.keys =
    {
      -- Attributes
      reset = 0 -- reset attribute
    , clear = 0 -- clear attribute
    , default = 0 -- default property
    , bright = 1 -- highlight
    , dim = 2 -- dark
    , underline = 4 -- underline
    , blink = 5 -- flashing
    , reverse = 7 -- reverse color
    , hidden = 8 -- hidden text

      -- Foreground
    , black = 30
    , red = 31
    , green = 32
    , yellow = 33
    , blue = 34
    , magenta = 35
    , cyan = 36
    , white = 37

        -- Background color
    , onblack = 40
    , onred = 41
    , ongreen = 42
    , onyellow = 43
    , onblue = 44
    , onmagenta = 45
    , oncyan = 46
    , onwhite = 47

In addition to color highlighting, if your terminal is under macosx, lion above the system, xmake can also support the display of emoji expressions, for systems that do not support Ignore the display, for example:

    cprint("hello xmake${beer}")
    cprint("hello${ok_hand} xmake")

The above two lines of code, I printed a classic beer symbol in the homebrew, the following line printed an ok gesture symbol, is not very dazzling. .

All emoji emoticons, as well as the corresponding keys in xmake, can be found in emoji. .

Version 2.1.7 supports 24-bit true color output, if the terminal supports it:

import("core.base.colors")
if colors.truecolor() then
    cprint("${255;0;0}hello")
    cprint("${on;255;0;0}hello${clear} xmake")
    cprint("${bright 255;0;0 underline}hello")
    cprint("${bright on;255;0;0 0;255;0}hello${clear} xmake")
end

Xmake's detection support for truecolor is implemented by the $COLORTERM environment variable. If your terminal supports truecolor, you can manually set this environment variable to tell xmake to enable truecolor support.

It can be enabled and tested with the following command:

$ export XMAKE_COLORTERM=truecolor
$ xmake --version

We can disable color output with XMAKE_COLORTERM=nocolor, or switch to plain theme to disable. xmake g --theme=plain
