khash.h
(http://attractivechaos.github.io/klib/#Khash%3A%20generic%20hash%20table) is a part of klib library in C. I want to covert it to D in the process of learning deeper about D.
First I tried with Dstep
(https://github.com/jacob-carlborg/dstep) and read the C to D
article (https://dlang.org/ctod.html). I managed to covert the
basic statements to D, but all multiline 'define' macros are
stripped off. So I am trying to recreate them with D way. For
example:
#define __KHASH_TYPE(name, khkey_t, khval_t) \
typedef struct kh_##name##_s { \
khint_t n_buckets, size, n_occupied, upper_bound; \
khint32_t *flags; \
khkey_t *keys; \
khval_t *vals; \
} kh_##name##_t;
I changed to:
template __KHASH_TYPE(string name){
"struct kh_" ~ name ~"_t { " ~
"khint_t n_buckets, size, n_occupied,
upper_bound; " ~
"khint32_t *flags; " ~
"khkey_t *keys; " ~
"khval_t *vals; " ~
"}"
}
// NEXT: use mixin with this template.
I am currently get a bit intimidated looking at KHASH_INIT2 macro
in khash.c. How do I convert this to the equivalent and idiomatic
D?
