Installation

haxelib git holi_macros <github url>Description
Macro helper utilities for some of your macro needs. The goal is to keep updating this project with new solutions.
Usage
MacroHelper.autoOptionalArg
What it does: All public attributes of a class as optional constructor arguments
Parameters: optional regex string of variable names to exclude
How to use:
@:build(holi_macros.MacroHelper.autoOptionalArg('^(?!_|name).+'))
class Potato
{
public var name:String;
public var taste:String;
public var color:Int;
public var size:Float;
public var _value:Int;
public function new():Void
{
name = '$taste and $color';
}
}The constructor will look like this:
new Potato(?color:Int, ?size:Float, ?taste:String);Note the optional regex '^(?!_|name).+' which excludes variable names starting with an underscore or variable names matching name.
MacroHelper.ClassBuilder
What it does: Helps making build macros
How to use:
// a build macro that does nothing
macro static function myBuildMacro1():Array<Field>
{
var builder = new holi_macros.MacroHelper.ClassBuilder(
Context.getLocalType(),
Context.toComplexType(Context.getLocalType()),
Context.getBuildFields()
);
return builder.toFields();
}
// a build macro adds a static variable
macro static function myBuildMacro2():Array<Field>
{
var builder = new holi_macros.MacroHelper.ClassBuilder(
Context.getLocalType(),
Context.toComplexType(Context.getLocalType()),
Context.getBuildFields()
);
var myvariable = new holi_macros.MacroHelper.MVariable(
'potato',
Context.currentPos(),
[APublic, AStatic],
macro:String
);
builder.variables.set('potato', myvariable);
return builder.toFields();
}
// add an first argument and expression to the constructor
macro static function myBuildMacro3():Array<Field>
{
var builder = new holi_macros.MacroHelper.ClassBuilder(
Context.getLocalType(),
Context.toComplexType(Context.getLocalType()),
Context.getBuildFields()
);
var constructor = getOrCreateConstructor(builder, Context.currentPos());
constructor.addArgFirst({name:"tomato", type: macro:String, opt:true});
constructor.addExpr(macro {trace(tomato);});
builder.functions.set('new', constructor);
return builder.toFields();
}
