This is a work in progress, spec compliant, HTML parser built with Zig.
- Tokenizer (missing a few edge cases)
- Parser (in progress)
- JavaScript DOM API support
The Tokenizer struct provides a (mostly) fully featured HTML tokenizer built according to the WHATGW HTML Spec. It is a streaming tokenizer which takes as input a full document, processes the document character by character, and emits both Tokens and ParseErrors. An example usage of it by itself could look like this:
const std = @import("std");
const Tokenizer = @import("zhtml/tokenizer.zig").Tokenizer;
pub fn main() void {
var allocator = std.heap.page_allocator;
var tokenizer = try Tokenizer.initWithFile(alloc, "./test.html");
while (true) {
var token = self.tokenizer.nextToken() catch |err| {
std.debug.warn("{} (line: {}, column: {})\n, .{ err, tokenizer.line, tokenizer.column });
continue;
};
if (token) |tok| {
switch (tok) {
Token.EndOfFile => break,
else => std.debug.warn("{}\n", .{ tok });
}
}
}
}though the Tokenizer is meant to be used in conjunction with the Parser.
Work in progress. Check back later.
