Decorator is a simple library for adding comments onto lines of text, primarily aimed at user-friendly error messages.
The colouring abilities are powered by JANSI, a betterC compatible ANSI library.
For example:
The above output was generated from the following code:
import core.stdc.stdio;
DecoratorBC!(1, 1, 1, 3) d;
d.addLine("printf(\"%s\", 400)", "main.c", 5);
d.colourLine(0, 0, 6, AnsiStyleSet.init.fg(Ansi4BitColour.yellow));
d.colourLine(0, 7, 11, AnsiStyleSet.init.fg(Ansi4BitColour.magenta));
d.colourLine(0, 13, 16, AnsiStyleSet.init.fg(Ansi4BitColour.cyan));
d.addTopComment(0, 8, "%s was specified.");
d.colourTopComment(0, 0, 0, 3, AnsiStyleSet.init.fg(Ansi4BitColour.green));
d.addBotComment(0, 13, "But a %d value was passed");
d.colourBotComment(0, 0, 6, 8, AnsiStyleSet.init.fg(Ansi4BitColour.red));
d.toString((const(char)[] str){ printf("%.*s", cast(int)str.length, str.ptr); });
