e8b4befd1e Further improved parsing of <SCRIPT> tag.
Script code may contain a '<' as part of a equation. We erroneously interpreted that as start of a tag. Now we check for the very next char to be a '/' as the only tag allowed is the </SCRIPT> tag.

9b9b92be06 Improved parsing of <SCRIPT> tag.
Complex script code tends to contain other tags inside strings. As we generally don't parse strings we erroneously interpreted those tags. The easiest workaround is to not interpret tags at all until the </SCRIPT> tag is found.

a8837e230c Removed support for <FRAME> tag.
Framesets aren't used nowadays anymore so it seems reasonable to remove support for them in order to save some space.

980d055f72 Allow for attributes in <li> tags.
parse_tag() is called both for attributes inside a tag and the end of the tag itself. For most tags parse_tag() doesn't distinguish both cases. This means that the "tag action" is additionally triggered for every tag attribute. When the tag "action" is setting some state this doesn't hurt. For many tags the "tag action" is to render a newline. Superfluous newlines are sort of acceptable to keep the code as small as possible. However the <li> "tag action" is to render a newline followed by an asterisk - and superfluous asterisks are ugly so we check for <li> if parse_tag() was called for the end of the tag itself.

a56af59f40 Avoid randomly "eating" blanks.
At the time do_word() is called s.word[s.wordlen] is undefined. So it doesn't make sense to make decisions based on its value - and in fact I don't see why it was necessary/desirable in the first place.

66fa843389 Added support for <input type='hidden'>.
Hidden form fields are aded to the page attribute buffer like text form fields so there's no need for special treatment in formsubmit(). However they are not added as widgets to the window so there's no user interaction.

c7b8bac006 Reorganized web page attribute data handling.
- Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs.

- Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it  is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer.

- Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered.

- Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.

d5d646528e Added support for self closing tags.
XHTML requires self closing tags to be used for empty tags, so we need to recognize them.

374c89be01 Added newline on </div>.
The tag <div> (in contrast to the tag <span>) is normally used to denote content placed on a line by its own. So it makes sense to trigger a newline when </div> is processed.

eac68071eb Changed the maximum length of a single word from 40 to match the page width. Browsers wider than 40 cols can now render longer words. Browsers smaller than 40 cols avoid display inconsistencies on long words (and save memory). Additionally simplified word truncation code. 2006-10-06 21:34:59 +00:00

e8ff2ba595 With the change to always position the cursor at the end of the exsisting text on entering the textentry field edit state it became necessary to avoid initializing textentry fields with blanks insteads of zeros.
Unfortunately I overlooked the dynamically created textentry fields for web forms. Changing their behaviour was a little more complicated as the length of the existing text was used to determine the size of the textentry field. Now this size is passed explicitly.
