New Zig formal grammar (#1685) Reverted #1628 and changed the grammar+parser of the language to not allow certain expr where types are expected 2018-11-13 21:08:37 +08:00			`var _mh_execute_header = extern struct {x: usize}{.x = 0};`

syntax: functions require return type. remove `->` The purpose of this is: * Only one way to do things * Changing a function with void return type to return a possible error becomes a 1 character change, subtly encouraging people to use errors. See #632 Here are some imperfect sed commands for performing this update: remove arrow: ``` sed -i 's/\(\bfn\b.\)-> /\1/g' $(find . -name ".zig") ``` add void: ``` sed -i 's/\(\bfn\b.\))\s{/\1) void {/g' $(find ../ -name "*.zig") ``` Some cleanup may be necessary, but this should do the bulk of the work. 2018-01-25 17:10:11 +08:00			`export fn add(a: i32, b: i32) i32 {`
