Renders tags (and objects that can be converted into tags using
as.tags()
) into HTML. (Generally intended to be called from web
framework libraries, not directly by most users--see
print.html()
for higher level rendering.)
renderTags(x, singletons = character(0), indent = 0)
doRenderTags(x, indent = 0)
Tag object(s) to render
A list of singleton signatures to consider already rendered; any matching singletons will be dropped instead of rendered. (This is useful (only?) for incremental rendering.)
Initial indent level, or FALSE
if no indentation should
be used.
renderTags
returns a list with the following variables:
head
: An HTML()
string that should be included in <head>
.
singletons
: Character vector of singleton signatures that are
known after rendering.
dependencies
: A list of resolved htmlDependency()
objects.
html
: An HTML()
string that represents the main HTML that was rendered.
doRenderTags
returns a simple HTML()
string.
doRenderTags
is intended for very low-level use; it ignores
render hooks, singletons, head, and dependency handling, and simply renders the given tag
objects as HTML. Please use renderTags()
if x
has not already handled its dependencies
and render hooks.
