Bug ID: 399427
Summary: How to configure the fonts and background color of the
"preview of rendered R Markdown"
Product: rkward
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: rkward-***@kde.org
Reporter: ***@gmail.com
Target Milestone: ---

SUMMARY

My desktop environment is GNOME and using the dark themes "Adwaita-dark". I
found that, the results of the function "preview R markdown" can't read. It is
because the themes "Adwaita-dark" forces all the background to black. However,
the default font color of the preview also in black.

Are there any ways to configure the font color of the "preview R markdown" ?

Thanks.

--- Comment #1 from Thomas Friedrichsmeier <***@ruhr-uni-bochum.de> ---
Well, this is a partial answer at best, but you can influence the text colors
of the output by adding meta and style information at the top of the .Rmd.
E.g.:

---
title: "Habits"
output:
html_document:
highlight: espresso
---
<style type="text/css">
body p {
color: #CCCCCCCC;
}
</style>

The "highlight" affects the R highlighting colors, only, while to change the
default text color, apparently you have to use CSS. (It would be possible to
control both via CSS).

I do not really have an idea on how this could be handled automatically from
within RKWard. I suppose we could add a setting to specify a custom CSS for
.Rmd previews, but that would both need manual action, _and_ it would override
whatever is specified in the .Rmd header.

Let me know, if anybody has a good idea on this.
