How I can arrange things in my project such that I can call my own Haxe library code from a Python script?
Thanks!

I realize that I need to first compile my Haxe code to Python, and then access the _resulting_ Python code from Python.
Ah. Ok. I need to back up: How can set up and build my own Haxe library, compiling it to a Python library?
Does this look ok and customary for Haxe?
```haxe
$ cd ~/dev/my-haxe-libs/my-lib-foo
$ tree -F
.
├── LICENSE.txt
├── py.hxml
├── pylib/
│ └── my_pkg/
├── README.md
└── src/
└── my_pkg/
└── MyModule.hx
```
where my py.hxml file looks like:
```haxe
-p src
-m my_pkg.MyModule
--python pylib/my_pkg/MyModule.py
```
and MyModule.hx contains:
```haxe
package my_pkg;
class MyModule {
public static function foo() {
trace("hi");
}
}
```
but running `haxe py.hxml` gives me this error:
```haxe
$ haxe py.hxml
src/my_pkg/MyModule.hx:3: lines 3-7 : Invalid -main : my_pkg.MyModule does not have static function main
```
I don’t have a `main` because this is a library, but commenting out the “`-m`” line from py.hxml leaves me with the compiler apparently not happy with it.
Thanks!

Just omit the `-m`, but keep the rest of the line - you’re not compiling a main class, you want to compile that module.

Hello,
If you want to export your code as a library, you do not have to define main class.
You can find an example of library export here: [Compiling libraries without main class - Compilation - Haxe programming language cookbook](https://code.haxe.org/category/compilation/compiling-libraries-without-main-class.html)

Ooof!! Got it now. Thanks!

Funny. Although my haxe code is in package `my_pkg`, the resulting Python module is not, but instead the class is named “`my_pkg_MyModule`”.
Anyhow, it works. Thanks!

On some targets like Python and JS, packages are “flattened”, which helps performance a bit. On JS. you can avoid this with `-D js-unflatten`, doesn’t look like there’s an equivalent for Python.
