=====

----------
+ chapter 2 - 4.1 of Wirth's [compiler book](http://www.ethoberon.ethz.ch/WirthPubl/CBEAll.pdf)
stretch buffers:
+ dynamically growable arrays such that with a few pitfalls but is easy to generate
+ invented by stb?
2018-03-22 (day 2)
------------------
+ lexing: char stream to token stream
+ ex. '1234 (x+y)' translates to '1234' '(' 'x' '+' 'y' ')'
+ no semantics yet
+ simple hand-written approach
+ mark: 1:17:34
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
