Jens-G edited a comment on issue #1567: THRIFT-4496: python specific list of
keywords for python generator
URL: https://github.com/apache/thrift/pull/1567#issuecomment-400819747
At least in theory it seems simple. In practice it may require some more
work (but only once).
1. Get rid of that global thing or reduce it down to the absolute minimun.
Place a big comment on to and below that anybody who is ever going to add a
keywored to that list without a really good reason will be punished
(methaporically speaking, of course).
2. Create a mechanism flexible enough to suit the needs of all code
generators that deals with language-specific Keywords.
3. Every morning repeat the mantra "**The issue is the code generation, not
the IDL. It's the generator, not the parser.**"
```
IDL ==> Model / AST ==> Generated Code
not not ... but ^ here
here here is the issue!
```

> Dealing with language keywords in Thrift (e.g. service method names)
> --------------------------------------------------------------------
>
> Key: THRIFT-4496
> URL: https://issues.apache.org/jira/browse/THRIFT-4496
> Project: Thrift
> Issue Type: New Feature
> Components: Compiler (General)
> Reporter: Vera Filippova
> Priority: Minor
>
> Apache Thrift compiler doesn't allow to use keywords in any of supported
> languages as field names. However, there are other compilers, like Scrooge,
> which do allow using some keywords as field identifiers, which leads to
> incompatibility.
> Assume we had a service with 'delete' method, with Java code generated by
> Scrooge. Now we'd like to generate Python code with Apache Thrift, but
> encounter an error because of the 'delete' keyword.
> I understand that using only Apache Thrift compiler, a user will never
> encounter this problem, but I think enabling keywords by request seems
> feasible.
> h1. Proposal
> It's possible to tweak keywords on code generation stage, e.g. use 'delete_'
> as a name of a generated function instead of 'delete', then use the original
> method name for a protocol message: writeMethodBegin('delete').
> This feature could be enabled with an additional flag, e.g. --screen-keywords.
> I have a draft for python generator here [https://github.com/nsrtvwls/thrift]
> The questions are, is this functionality welcome? If yes, would it require to
> have it supported for all languages?
