2019-05-15improvements to zig's implementation of libc and WebAssemblyAndrew Kelley
* rename std/special/builtin.zig to std/special/c.zig not to be confused with @import("builtin") which is entirely different, this is zig's multi-target libc implementation. * WebAssembly: build-exe is for executables which have a main(). build-lib is for building libraries of functions to use from, for example, a web browser environment. - for now pass --export-all for libraries when there are any C objects because we have no way to detect the list of exports when compiling C code. - stop passing --no-entry for executables. if you want --no-entry then use build-lib. * make the "musl" ABI the default ABI for wasm32-freestanding. * zig provides libc for wasm32-freestanding-musl.

2019-03-02compile error for import outside package pathAndrew Kelley
closes #2024 there's a new cli option `--main-pkg-path` which you can use to choose a different root package directory besides the one inferred from the root source file and a corresponding build.zig API: foo.setMainPkgPath(path)

2018-06-17remove integer and float casting syntaxAndrew Kelley
* add `@intCast` * add `@floatCast` * add `@floatToInt` * add `@intToFloat` See #1061
2018-06-09breaking syntax change: ??x to x.? (#1095)Andrew Kelley
See #1023 This also renames Nullable/Maybe to Optional
2018-06-04disallow single-item pointer indexingAndrew Kelley
add pointer arithmetic for unknown length pointer
2018-05-31use * for pointer type instead of &Andrew Kelley
See #770 To help automatically translate code, see the zig-fmt-pointer-reform-2 branch. This will convert all & into *. Due to the syntax ambiguity (which is why we are making this change), even address-of & will turn into *, so you'll have to manually fix thes instances. You will be guaranteed to get compile errors for them - expected 'type', found 'foo'

2018-01-25syntax: functions require return type. remove `->`Andrew Kelley
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.

2018-01-22add new kind of test: generating .h files. and moreAndrew Kelley

See #661 * add compile errors for non-extern struct, enum, unions in function signatures * add .h file generation for extern struct, enum, unions

2017-08-19bit shifting safetyAndrew Kelley
* add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7 * shift operations shift amount parameter type is integer with log2 bit width of other param - This enforces not violating undefined behavior on shift amount >= bit width with the type system * clean up math.log, math.ln, math.log2, math.log10 closes #403
2017-08-09more intuitive left shift and right shift operatorsAndrew Kelley
Before: * << is left shift, not allowed to shift 1 bits out * <<% is left shift, allowed to shift 1 bits out * >> is right shift, allowed to shift 1 bits out After: * << is left shift, allowed to shift 1 bits out * >> is right shift, allowed to shift 1 bits out * @shlExact is left shift, not allowed to shift 1 bits out * @shrExact is right shift, not allowed to shift 1 bits out Closes #413
2017-06-17std: refactor pow to be genericAndrew Kelley
2017-05-06builtin functions for division and remainder divisionAndrew Kelley
* add `@divTrunc` and `@divFloor` functions * add `@rem` and `@mod` functions * add compile error for `/` and `%` with signed integers * add `.bit_count` for float primitive types closes #217
2017-05-03change while syntaxAndrew Kelley
Old: ``` while (condition; expression) {} ``` New: ``` while (condition) : (expression) {} ``` This is in preparation to allow nullable and error union types as the condition. See #357

2017-03-26add stack protector safety when linking libcAndrew Kelley
* introduce zigrt file. it contains only weak symbols so that multiple instances can be merged. it contains __zig_panic so that multiple .o files can call the same panic function. * remove `@setFnVisible` builtin and add @setGlobalLinkage builtin which is more powerful * add `@panic` builtin function. * fix collision of symbols with extern prototypes and internal function names * add stack protector safety when linking against libc. To add the safety mechanism without libc requires implementing Thread Local Storage. See #276
