html_ostream
classThe html_ostream
class supports output to any destination, in HTML
syntax. Its type is ‘html_ostream_t’. It is a subclass of
‘ostream_t’.
It can be instantiated through this function:
Creates an output stream that takes input in the UTF-8 encoding and
writes it in HTML form on destination
.
This stream produces a sequence of lines. The caller is responsible for
opening the <body><html>
elements before and for closing them
after the use of this stream.
Note: The resulting stream must be closed before destination
can be closed.
The class adds the following methods:
Starts a <span class="classname">
element. The
classname
is the name of a CSS class. It can be chosen
arbitrarily and customized through the CSS file.
Ends a <span class="classname">
element.
The html_ostream_begin_span
/ html_ostream_end_span
calls
must match properly.
Returns the referred URL of the currently set hyperlink, or NULL
if no hyperlink attribute is currently set.
Note: The returned string is only valid up to the next invocation of
html_ostream_set_hyperlink_ref
.
Sets or removes a hyperlink attribute.
To set a hyperlink attribute, pass a non-NULL
ref.
ref is an URL; it should be at most 2083 bytes long. Non-ASCII
characters should be URI-escaped (using the %nn syntax).
To remove a hyperlink attribute, pass NULL
for ref.
Hyperlinks don’t nest. That is, a hyperlink attribute is enabled only
up to the next invocation of html_ostream_set_hyperlink_ref
.
This function acts like ostream_flush (stream, FLUSH_THIS_STREAM)
,
except that it leaves the destination with the current text style enabled,
instead of with the default text style.
After calling this function, you can output strings without newlines(!) to the
underlying stream, and they will be rendered like strings passed to
ostream_write_mem
, ostream_write_str
, or ostream_printf
.
