zig-toml's Introduction

zig-toml

A TOML parser written in Zig targeting TOML v0.5.0. The end goal is for the program to be robust, with no crashing given any situation. Though, in its current state this program is probably far from that goal.

There is currently a lack of documentation but the tests contained should give enough of an idea on how to use this.

Quickstart Guide

Zig Version Support

This table shows the project's current compatibility status with zig:

Zig Version	Status
0.11.0	✅ Supported
0.10.1 and below	❌ Not Supported

Features

Building and Usage

This library is self-contained and requires no dependencies.

To build simply run zig build and that will output a file called libtoml.a that you can link with your program.

If you want to run the tests then use the zig build test command.

zig-toml's Issues

Bug: Parser panics and fails when parsing floats

This code panics

test "float" {
    var parser = try parseContents(std.testing.allocator,
        \\ foo=1.234
    );
    defer parser.deinit();

    var table = try parser.parse();
    defer table.deinit();

It seems to be related to the placement of the decimal

This code does not panic

test "float" {
    var parser = try parseContents(std.testing.allocator,
        \\ foo=12.34
    );
    defer parser.deinit();

    var table = try parser.parse();
    defer table.deinit();

`parseFile` leaks memory

Given the test case:

test "memory cleanup" {
    var table = try parseFile(std.testing.allocator, "test/basic.toml", null);
    defer table.deinit();
}

note that zig build test outputs:
