<jokke> hey
<jokke> i need some help writing c bindings
<jokke> i have a lib that uses a struct in a lot of places and i need to access one of its fields
<jokke> so i defined the struct in my lib
<jokke> the c functions that use the struct always get it by reference
<crystal-gh> [crystal] asterite closed pull request #2149: Improve Markdown (master...improve-markdown) https://git.io/vg127
<jokke> so i wrote a class that wraps the lib struct, provides access to the field i need and implements to_unsafe as pointerof(@struct)
<jokke> something goes very wrong though. I'm not exactly sure what, but apparently the c lib can't make much sense out of the struct
<jhass> chances are you defined it wrongly
<jhass> access field = read it?
<jokke> jhass: yes
<jokke> i'll paste the code. one sec
<jhass> make sure the sizeof(struct foo) in C is the same as the sizeof(LibFoo::Foo) in Crystal

<jokke> ah could it be the Allocater*?
<jokke> *Allocator
<jokke> wouldn't that make it a pointer to a pointer, or is it irrelevant
<jokke> since i'm not using it
<jhass> isn't out @buffer already defining a Pointer(Buffer), so pointerof(@buffer) makes a Pointer(Pointer(Buffer))? I don't remember
<jokke> but the compiler would surely tell me about it, right?
<jokke> yup
fowlduck has quit [Ping timeout: 240 seconds]
<jokke> it complains if i don't use the pointerof
<jokke> the code runs up until line 79 where i throw an exception
<jokke> so writing to the buffer seems to fail
<jokke> oh wait
<jokke> it doesn't fail
<jokke> wtf
<jokke> just took out line 79
<jokke> and i get html output

<jeromegn> will that latest change allow to pass variables to macros?

<jeromegn> well, not :sadpanda:, but yes. irccloud :)
<jeromegn> also embeds a bunch of stuff.
<thor77> oO
<thor77> ah, already heard about that
<thor77> seems like a bnc with some cool features
<thor77> but not open source :(
<jeromegn> indeed, that's a bit sad :(
