hy2py doesn't work for require multiple modules

[fatestigma]

It seems that hy2py only generates the last module in (require ...). It might be something wrong within hy_compile according to the generated AST.

Example source file test.hy:

(require
 [hy.contrib.loop [loop]]
 [hy.contrib.walk [let]])

Run with hy2py -sa test.hy:

HyExpression([
  HySymbol('do'),
  HyExpression([
    HySymbol('require'),
    HyList([
      HySymbol('hy.contrib.loop'),
      HyList([
        HySymbol('loop')])]),
    HyList([
      HySymbol('hy.contrib.walk'),
      HyList([
        HySymbol('let')])])])])


Module(
    body=[Import(names=[alias(name='hy.macros', asname=None)]),
        Expr(
            value=Call(
                func=Attribute(value=Attribute(value=Name(id='hy'), attr='macros'), attr='require'),
                args=[Str(s='hy.contrib.walk'), Name(id='None')],
                keywords=[
                    keyword(arg='assignments', value=List(elts=[List(elts=[Str(s='let'), Str(s='let')])])),
                    keyword(arg='prefix', value=Str(s=''))]))])


import hy.macros
hy.macros.require('hy.contrib.walk', None, assignments=[['let', 'let']],
    prefix='')

It might because Result.__add__ at compiler.py#L1207 (ret += self.compile(...))and compiler.py#L312 (result.expr = other.expr); I printed Result before and after parsing the second require.

# before adding
Result(imports=[],
       stmts=[],
       expr=Call(func=Attribute(value=Attribute(value=Name(id='hy', ctx=Load()), attr='macros', ctx=Load()), attr='require', ctx=Load()),
                 args=[Str(s='hy.contrib.loop'), Constant(value=None)], 
                 keywords=[keyword(arg='assignments', value=List(elts=[List(elts=[Str(s='loop'), Str(s='loop')], ctx=Load())], ctx=Load())), keyword(arg='prefix', value=Str(s=''))]))

# after adding
Result(imports=[],
       stmts=[],
       expr=Call(func=Attribute(value=Attribute(value=Name(id='hy', ctx=Load()), attr='macros', ctx=Load()), attr='require', ctx=Load()),
                 args=[Str(s='hy.contrib.walk'), Constant(value=None)],
                 keywords=[keyword(arg='assignments', value=List(elts=[List(elts=[Str(s='let'), Str(s='let')], ctx=Load())], ctx=Load())), keyword(arg='prefix', value=Str(s=''))]))

Thanks for pointing my attention to the right place. It was a missing expr_as_stmt, of course.
