@include "path/to/file.pml";

[vvoovv]

@include inserts grammar definition from another file defined by the path:

@include "path";

Includes can be recursive.

It's desired to track down the original PML file and the line number in the original PML file for each line in the resulting PML definition.

Examples:

@include "a/b/c.pml";
@include "a.pml";
@include  "../../a/b/c.pml";

Below is the special case. The leading slash means lookup in the folder where the asset packages are stored:

@include "/default/a/b/c.pml"

Includes can be recursive.

What do you mean by that? Normally, recursive includes are not allowed. For instance for a file A.pml

...
@inlcude "files/B.pml";
...

and a file B.pml

...
@inlcude "files/A.pml";
...

will start an infinite include loop. I will check for that and create an error message if found.

... lookup in the folder where the asset packages are stored

Where will this location be defined?

I meant hierarchical rather than recursive. A can include B, B can include C, C can include D and so on

It should be an external parameter to the translator.

[polarkernel]

I have commited a first version of @include. The translator requires now an additional parameter:

python PML2PythonTranslator.py pmlstyle.pml pathToAssets

The path pathToAssets must not have a slash at its end. The following features are included:

• Hierarchical inclusion to multiple levels is possible.
• Error messages include the file name and a local line number (track down).
• A leading slash in front of the file path leads to lookup in the assets folder.
• Recursive inlcusion is catched and produces an error message.
• A simple syntax check of the @include is implemented.

Let's see if this meets your requirements.

You are very fast!

Trying it out right now.

I've made a quick fix in the path: https://github.com/prochitecture/pml/blob/master/PML_Preprocessor.py#L62

Otherwise it would not work if the path were in the absolute form.

Good to have an experienced programmer in the team!

I changed the regular expression in _PMLPreprocessor.py from

        self.cmnt_patt = re.compile('//.*?\n')

to

        self.cmnt_patt = re.compile('//.*\n?')

The previous regular expression couldn't detect a comment in the last line of a file without the next line symbol.
