haxex, a short shell script that can be used so you have Haxe shell scripting

README.md

This is a tiny shell script that you can use to make scripting with Haxe very straight forward.

Using a straight #!/usr/bin/haxe doesn't work currently, as the Haxe compiler will have to be a little more clever about realising it is a shell script and that we wish to execute it. Maybe this will be native some day, for now, you can install the script below into /usr/bin/haxex and then use that.

Installation:

1. sudo nano /usr/bin/haxex, paste the 'haxex' file in there
2. sudo chmod +x /usr/bin/haxex

Usage:

#!/usr/bin/haxex
class MyScript 
{
public static function main() 
{
	trace('My Script is executing!');
}
}

Running:

chmod +x MyScript.hx
./MyScript.hx

Pretty neat-o if you ask me.

What this script actually does:

1. Reads the first argument as "filename"
2. Gets rid of the "./" at the start of $filename
3. Gets rid of the ".hx" at the end of $filename
4. Turns the "/" dir separators into "." package separators, in case your script is in a subpackage.

Limitations:

If your script is in the root package (has no package statement at the top of the file), then you need to call it from the directory the script is in. If your script is in a sub-package, you need to call it from the root-level package. Easy rule of thumb: don't use packages, and call from the directory the script is in.

HaxeScript.hx

#!/usr/bin/haxex

// Run with "./HaxeScript.hx some args here"

class HaxeScript 
{
	public static function main() 
	{
		trace('Hi, the following ${Sys.args().length} arguments were passed in:');
		for (a in Sys.args())
		{
			trace ('  $a');
		}
	}
}

haxex

#!/bin/bash

# First argument is the filename
filename=$1

# Remove "./" if it's there
filename=${filename/"./"/""}

# Remove ".hx" if it's there
filename=${filename/".hx"/""}

# Change "/" to "."
filename=${filename/"/"/"."}

haxe --run $filename ${@:2}

wow, can't believe I'm only discovering this now, wish it was packaged with Haxe

It seems like if I do "./HaxeScript.hx" then it breaks this. I added "set -x" to see what happened:

$ ./HaxeScript.hx 
+ filename=./HaxeScript.hx
+ filename=//HaxeScript.hx
+ filename=//HaxeScript
+ filename=//HaxeScript
+ /usr/bin/env haxe --run //HaxeScript
Error: Could not process argument //HaxeScript
