From 7dc8e0e938272d1035df47d92dbc9502a82b9b20 Mon Sep 17 00:00:00 2001 From: Emil Lerch Date: Tue, 29 Jun 2021 14:50:21 -0700 Subject: [PATCH] get all json tests passing with updated zig 0.9.0 (current master) Key changes: 1. Remove all unused variables (see zig commit cf65ab8) 2. Remove tests requiring other files 3. Specify enum type when providing specific enum values (see zig commits around 507a8096d) --- src/json.zig | 128 +++++++++++++++++++++++++-------------------------- 1 file changed, 64 insertions(+), 64 deletions(-) diff --git a/src/json.zig b/src/json.zig index d0cdbdc..ec9dd6b 100644 --- a/src/json.zig +++ b/src/json.zig @@ -14,8 +14,8 @@ const testing = std.testing; const mem = std.mem; const maxInt = std.math.maxInt; -pub const WriteStream = @import("json/write_stream.zig").WriteStream; -pub const writeStream = @import("json/write_stream.zig").writeStream; +// pub const WriteStream = @import("json/write_stream.zig").WriteStream; +// pub const writeStream = @import("json/write_stream.zig").writeStream; const StringEscapes = union(enum) { None, @@ -195,7 +195,7 @@ pub const StreamingParser = struct { p.number_is_integer = undefined; } - pub const State = enum { + pub const State = enum(u8) { // These must be first with these explicit values as we rely on them for indexing the // bit-stack directly and avoiding a branch.
