Could you create a new jinja file and put all those definitions in there?

[alexfandrianto, 2015/10/16 21:25:49]

I combined them into a macro (writeMojomTypeDef) inside mojom_type_macros.tmpl.

This file now calls into that macro. The reason that enum.tmpl, struct.tmpl,
union.tmpl, and interface.tmpl will have to call the writeMojomTypeDef macro is
to keep it all organized and together. (Since the interface.tmpl file also
defines some structs, it helps if the corresponding types are also defined by
that type's template.)

+  enumName_{{enum|name}} = "{{enum|name}}"
+{% for field in enum.fields %}
+  enumFieldName_{{enum|name}}_{{field|name}} = "{{field|name}}"
+{% endfor %}
+)
+
+func {{util.typeName(enum, typepkg, package)}}() {{typepkg}}MojomEnum {
+  return {{ mojom_type_macros.writeMojomType(typepkg, enum, package, exported) }}
+}
+
 {% endmacro %}
