stretch buffers:
|
|
+ dynamically growable arrays such that with a few pitfalls but is easy to generate

------------------
|
|
+ lexing: char stream to token stream
|
|
+ ex. '1234 (x+y)' translates to '1234' '(' 'x' '+' 'y' ')'
|
|

|
|
+ simple hand-written approach

dev log:
|
|
+ you can use a union with an anonymous struct to add fields to a struct maybe
|
|
|
|
struct Thing {
|
|
int type;
|
|
union {
|
|
uint64_t val;
|
|
struct {
|
|
int start;
|
|
int end;
|
|
};
|
|
};
|
|
};
|
|
+ C99 variadic debug macro:
|
|
|
|
#ifndef NDEBUG
|
|
#define tprint(...) do { fprintf(stderr, __VA_ARGS__); } while (false)
|
|
#else
|
|
#define tprint(...) do {} while (false)
|

#endif
