Inject CSS styling into RMD parametrization app #866

frankandrobot · 2016-11-11T17:36:37Z

Modified knit_params_ask so that it is possible to pass custom css/scripts, both as strings and as links to URIs.

Connected to #3945

This reverts commit 2858c1f.

One option that won't pollute the argument list so much is to have a single argument that accepts a named list.

html_head = list()

Then, if you want to specify some parts:

html_head = list(style = "body { font-size: 15px; }")

Not sure which would be preferred.

Sorry, when I replied in the email, it put the comments in the wrong place.
I initially had the same idea, but as per @trestletech , the long form is preferred.

You could indeed go either way. I agree with @trestletech that R tends to stylistically prefer long argument lists. Even though this isn't normally good form in more well decomposed systems in R where many operations tend to be top level "one button" ones it makes some sense (also forces documentation of the parameters in .Rd as a side benefit).

nit: all of our other param helper functions have "params" in their name. It's not the best namespacing, but it's something.

Ok tweaked as requested and added tests. This is re-ready for review @trestletech @aronatkins

aronatkins

Could we work through the Connect integration before calling this final? In particular, I'm interested in how we are going to hide the ok/cancel buttons, suppress the enter/escape handling, and inject ok/cancel actions from the parent iframe.

jjallaire · 2016-11-14T19:29:23Z

That's fine. We are going to ship a new version of rmarkdown CRAN around
the end of this week (to support the forthcoming IDE patch release). We are
happy to do another rmarkdown release in a month's time if this work misses
the current release.

Could we work through the Connect integrati I'm interested in how we aregoing to hide the ok/cancel buttons, suppress the enter/escape handling,and inject ok/cancel actions from the parent iframe.

This code is designed to override the defaults with the custom. So for
example, to supress the handling, if I recall correctly, it's just an event
that can be easily over ridden. The hiding is similar via css.

What is the use case to insert actions? In any case, all you do is insert
JavaScript to handle the actions.

Update: after taking a better look at the code, I noticed that there might be enough logic in the shiny R code for inputs, to keep this strategy from working for certain use cases, for example, default (blank) param support. @aronatkins we should touch base in the am so i can get a better idea of what the use cases are

I don't know what the common formatting is for this package, but you could consider styling with if \code{TRUE}, does not... Probably more important to align with the conventions of the package but just making sure you're aware of the option.
