i have now also fixed this long standing issue. now you can not only parse,
but also generate empty attributes, by setting an attribute's value to
character():
gen_tag_functions(
tags=c("input"),
envir=as.environment("XiMpLe_wrappers")
)
input_(type="checkbox", checked=character(), disabled=character())
# <input type="checkbox" checked disabled />
with the latest additions, XiMpLe can pretty much also be used to comfortably
maintain static HTML web projects. instead of templating, you write functions
that generate pages. i've also included a new function to deal with static
files (like CSS, JavaScript or web fonts) called provide_file(). here's an
example from ?provide_file:
my_HTML <- XMLNode(
"link",
rel="stylesheet",
type="text/css",
href=provide_file(
rel="static/css/bootstrap.min.css",
to="/tmp",
from="~/webpage/v1"
)
)
this would generate a <link> tag:
# <link rel="stylesheet" type="text/css" href="static/css/bootstrap.min.css"
# />
but instead of simply setting the href attribute, provide_file() looks for an
actual copy of that file at ~/webpage/v1/static/css/bootstrap.min.css and
writes a copy to the web project root, here /tmp/static/css/bootstrap.min.css.
this can also be used for images etc. it ensures that all referenced files are
actually available, and you can always regenerate a complete, working web
project from scratch. e.g., you can quickly examine what the complete web page
would look like with a different theme, behave with an updated bootstrap
version etc.
i have already realized a small web project using the package (it was actually
the driving force behind my recent work on XiMpLe) and am preparing to replace
the old PHP code of two much more complex pages in the near future with static
HTML this way.
i have also prepared rkwarddev to work with the new version. most work here
was getting the unit tests to run again because the new object class layout
had slightly changed. i finally decided to keep the old classes in the package
(otherwise it wouldn't have been possible to load saved objects that were
generated by older versions of XiMpLe) and added methods as_XiMpLe_node() and
as_XiMpLe_doc() to update these old objects.
in case you'd like to check it out:
devtools::install_github("rkward-community/XiMpLe", ref="develop")
i'm planning to upload this to CRAN shortly, so if you run into issues, please
drop me a note :)
