Synopsis
#include <gumbo.h>
Data Fields
GumboAllocatorFunction allocator
GumboDeallocatorFunction deallocator
void * userdata
int tab_stop
bool stop_on_first_error
int max_errors
GumboTag fragment_context
GumboNamespaceEnum fragment_namespace
Detailed Description
Input struct containing configuration options for the parser. These let you specify alternate memory managers, provide different error handling, etc. Use kGumboDefaultOptions for sensible defaults, and only set what you need.
Field Documentation
GumboAllocatorFunction GumboOptions::allocator
A memory allocator function. Default: malloc.
GumboDeallocatorFunction GumboOptions::deallocator
A memory deallocator function. Default: free.
void* GumboOptions::userdata
An opaque object that's passed in as the first argument to all callbacks used by this library. Default: NULL.
int GumboOptions::tab_stop
The tab-stop size, for computing positions in source code that uses tabs. Default: 8.
bool GumboOptions::stop_on_first_error
Whether or not to stop parsing when the first error is encountered. Default: false.
int GumboOptions::max_errors
The maximum number of errors before the parser stops recording them. This is provided so that if the page is totally borked, we don't completely fill up the errors vector and exhaust memory with useless redundant errors. Set to -1 to disable the limit. Default: -1
GumboTag GumboOptions::fragment_context
The fragment context for parsing: https://html.spec.whatwg.org/multipage/syntax.html#parsing-html-fragments
If GUMBO_TAG_LAST is passed here, it is assumed to be "no fragment", i.e. the regular parsing algorithm. Otherwise, pass the tag enum for the intended parent of the parsed fragment. We use just the tag enum rather than a full node because that's enough to set all the parsing context we need, and it provides some additional flexibility for client code to act as if parsing a fragment even when a full HTML tree isn't available.
Default: GUMBO_TAG_LAST
GumboNamespaceEnum GumboOptions::fragment_namespace
The namespace for the fragment context. This lets client code differentiate between, say, parsing a <title> tag in SVG vs. parsing it in HTML. Default: GUMBO_NAMESPACE_HTML
