1 | h1. wac - Windows ANSI Color
2 |
3 | wac.exe is a small command line utility that lets you use ANSI colors on Windows. This will print nice colors:
4 |
5 |
6 | printcol.bat | wac
7 |
8 |
9 | This will not:
10 |
11 |
12 | printcol.bat
13 |
14 |
15 | h2. Why wac?
16 |
17 | Some command line tools (like "Cucumber":http://cukes.info) like to print ANSI colors.
18 | Since Windows has no idea what ANSI colors are, all you'll see is gibberish. Unless
19 | you use wac.
20 |
21 | h2. But we have Win32::Console
22 |
23 | I know that Perl, Ruby, Python etc have native libraries that will do ANSI coloring on Windows,
24 | but not all platforms have that. If you're using e.g. JRuby on Windows there is no such
25 | library. So wac will save you.
26 |
27 | h2. Download/Installation
28 |
29 | Just download "wac.exe":http://github.com/aslakhellesoy/wac/raw/master/wac.exe and put it somewhere on your PATH.
30 |
31 | h2. How does it work?
32 |
33 | wac.exe reads from STDIN and prints to STDOUT. While doing that it looks for ANSI color codes, and if it finds one,
34 | it sets the console color accordingly and strips away the color code from the output.
35 |
36 | h2. How do I build it?
37 |
38 | Just get MinGW and run:
39 |
40 |
41 | gcc -o wac wac.c
42 |
43 |
44 | h2. Why is it in C?
45 |
46 | Because it's easy to change colors on Windows with C.
47 |
48 | h2. Why is the C code so bad?
49 |
50 | Because I never do C. Feel free to improve that.
51 |
52 | h2. I have found a bug
53 |
54 | Great. Just fork this Git repo, clone your fork and fix it.
55 | When you have pushed your changes back to your repo, send me a pull request.
56 |
57 | h2. I have found a bug, but I don't know C.
58 |
59 | I don't know C either. Find someone who does.
