that's all this commit does. further commits will fix cli flags and such. see #2221
2019-06-09different array literal syntax when inferring the sizeAndrew Kelley
old syntax: []i32{1, 2, 3} new syntax: [_]i32{1, 2, 3} closes #1797

2019-02-08std.debug.assert: remove special case for test buildsAndrew Kelley
Previously, std.debug.assert would `@panic` in test builds, if the assertion failed. Now, it's always `unreachable`. This makes release mode test builds more accurately test the actual code that will be run. However this requires tests to call `std.testing.expect` rather than `std.debug.assert` to make sure output is correct. Here is the explanation of when to use either one, copied from the assert doc comments: Inside a test block, it is best to use the `std.testing` module rather than assert, because assert may not detect a test failure in ReleaseFast and ReleaseSafe mode. Outside of a test block, assert is the correct function to use. closes #1304
2018-11-13New Zig formal grammar (#1685)Jimmi Holst Christensen
Reverted #1628 and changed the grammar+parser of the language to not allow certain expr where types are expected
2018-10-15Solve the return type ambiguity (#1628)Jimmi Holst Christensen
Changed container and initializer syntax * <container> { ... } -> <container> . { ... } * <exrp> { ... } -> <expr> . { ...}
2018-06-17remove integer and float casting syntaxAndrew Kelley
* add `@intCast` * add `@floatCast` * add `@floatToInt` * add `@intToFloat` See #1061
2018-05-29run zig fmt on the codebaseAndrew Kelley
See #1003
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.
2017-12-23move std/debug.zig to a subdirectoryAndrew Kelley
self hosted compiler parser tests do some fuzz testing
2017-12-22std.math: remove unnecessary inline calls andAndrew Kelley
workaround windows 32 bit test failure See #537
2017-12-22explicitly return from blocksAndrew Kelley
instead of last statement being expression value closes #629
2017-08-28remove workaround for LLVM not respecting "nobuiltin"Andrew Kelley
now that we depend on LLVM 5.0.0 we can remove the workaround. closes #393
2017-08-20std.math: remove constants that can be derivedAndrew Kelley

2017-06-20Add math special case tests and general fixesMarc Tiehuis
- Should cover special case inputs for most functions - Fixed a number of runtime panicking behaviour reliant on shift overflow/division by zero etc.
2017-06-19workaround for llvm bugAndrew Kelley
See #393 for details
2017-06-16Add math libraryMarc Tiehuis
This covers the majority of the functions as covered by the C99 specification for a math library. Code is adapted primarily from musl libc, with the pow and standard trigonometric functions adapted from the Go stdlib. Changes: - Remove assert expose in index and import as needed. - Add float log function and merge with existing base 2 integer implementation. See https://github.com/tiehuis/zig-fmath. See #374.
