SimpleHTML

Very primitive HTML parser oh yeah, one more!

Why?

I want to parse a lot of small html-like chunks to a NSAttributedString in background. So, I can do something like Android guys doing with android.text.Html and then we can do primitive formatted text on the backend...

But I hate to do it with build-in main-thread-only parser from UIKit:

    [[NSAttributedString alloc] initWithData:[html dataUsingEncoding: NSUTF8StringEncoding]
                                     options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                                               NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding),
                                               NSDefaultAttributesDocumentAttribute:@{
                                                        NSFontAttributeName : [UIFont systemFontOfSize:SystemFontSize]
                                                        }}
                          documentAttributes: nil
                                       error: &error];

When I need only that:

Bold: important italic message

Bold: important italic message

Ok, what I can do with it?

Well, not much, as it is designed to be small, fast, one thing

Tags currently supported:

  <a>   - very nasty way, though

Some well-known symbols:

& - makes &

  - replaced by simple space

How does it look like to parse?

    OSSimpleHTML *htmlParser = [[OSSimpleHTML alloc] initWithBasicTextAttributes:@{}];
    NSAttributedString *labelText = [htmlParser attributedStringFromHTML:@"<b>Bold:</b> important <i>italic</i> message"];

I want to make my text red color xxx font by default:

UIFontDescriptor *descriptor = [UIFontDescriptor preferredFontDescriptorWithTextStyle:UIFontTextStyleHeadline];
UIFont *font = [UIFont fontWithDescriptor:descriptor size:descriptor.pointSize];

OSSimpleHTML *htmlParser = [[OSSimpleHTML alloc] initWithBasicTextAttributes:@{
                                                                               NSForegroundColorAttributeName : [UIColor redColor],
                                                                               NSFontAttributeName : font
                                                                               }];

Is it thread-safe?

Not yet. But you can send a MR =^^=
