> Key: THRIFT-544
> URL: https://issues.apache.org/jira/browse/THRIFT-544
> Project: Thrift
> Issue Type: Bug
> Components: Compiler (General)
> Affects Versions: 0.2
> Reporter: Ben Taitelbaum
> Assignee: Ben Taitelbaum
> Priority: Minor
> Fix For: 0.4
>
> Attachments: thrift-544_add_enum_name_to_enum_keys.patch,
> thrift-544_prevent_redefining_consts.patch
>
>
> The current generator produces multiple -define statements with the same
> name, which isn't valid erlang code (and also isn't valid semantically if we
> want two different values).
> {code:title=EnumTest.thrift|borderStyle=solid}
> enum MyType1 {
> A = 0,
> B = 1
> }
> enum MyType2 {
> A = 2,
> C = 4
> }
> {code}
> produces:
> {code:title=enumTest_types.hrl|borderStyle=solid}
> -ifndef(_enumTest_types_included).
> -define(_enumTest_types_included, yeah).
> -define(enumTest_A, 0).
> -define(enumTest_B, 1).
> -define(enumTest_A, 2).
> -define(enumTest_C, 4).
> -endif.
> {code}
> In the patched version, it produces this:
> {code:title=enumTest_types.hrl|borderStyle=solid}
> -ifndef(_enumTest_types_included).
> -define(_enumTest_types_included, yeah).
> -define(enumTest_MyType1_A, 0).
> -define(enumTest_MyType1_B, 1).
> -define(enumTest_MyType2_A, 2).
> -define(enumTest_MyType2_C, 4).
> -endif.
