Description Andrej Mitrovic 2011-07-01 22:24:57 UTC 
E.g.:

typedef struct _cairo_device cairo_device_t;

htod translates this incorrectly to:
alias _cairo_device cairo_device_t;

The closest D idiom to this is:
typedef void cairo_device_t;

Or if typedef is ultimately killed maybe alias would work:
alias void cairo_device_t;

There's a ton of this stuff in C header files. :/
Comment 1 Andrej Mitrovic 2011-07-01 22:27:52 UTC 
For what it's worth this helps for us porting monkeys:

regex: alias \w+
replace with: typedef void

But you have to do this manually..
Comment 2 Andrej Mitrovic 2011-07-01 22:33:59 UTC 
Well crap that's not good, it needs to be:
typedef void cairo_device_t;
typedef void _cairo_device;

Stupid C APIs!
Comment 3 Mike Parker 2011-07-02 04:05:53 UTC 
Wouldn't it be more appropriate to translate it as:

struct cairo_device_t {}
Comment 4 Jacob Carlborg 2011-07-02 06:08:47 UTC 
The most correct translation would be:

struct cairo_device_t;
Comment 5 Andrej Mitrovic 2016-08-27 22:06:15 UTC 
dstep supports this feature (https://github.com/jacob-carlborg/dstep), marking as wontfix.
