An outlook on RKWard 0.8.2 and call for testing

[Thomas Friedrichsmeier]

Hi,

here's a quick pointer to two new features in RKWard, which should both
come in quite handy to power users, but may not be immediately visible.
It would be great, if you could have a look, and help find any
remaining problems, so we can soon roll this into a 0.8.2 release.

As usual, current development builds can be found at
https://cdn.kde.org/ci-builds/education/rkward/master/ .

The first new feature is "(Quick) Code Navigation". This allows to
navigate, select, and run code based on the its parsed structure,
rather than just line by line. In a script Window, right-click to
bring up a context menu, and select one of the available navigation
options (e.g. going backwards to the start of a toplevel statement,
such as a function definition). To perform a sequence of steps, much
faster, hit Meta+N (shortcut configurable) to enter quick code
navigation mode. E.g.: "Tsr" to select and run the current toplevel
statement. "nnnn" to step over statements in way reminding of R's
debugger (browser()), except without actually executing the code, an
also allowing you to go backwards ("N"). "i" and "o" to move to inner
or outer contexts, "c" to jump to the next code chunk in an .Rmd-file,
etc.

Another addition is not actually an all new feature, but a much
enhanced one: The "R Console" preview mode (again, in script windows),
now also includes further options, and, importantly, graphs. This even
allows to track the evolution of a plot statement by statement.

Regards
Thomas
