In asciicast: Create 'Ascii' Screen Casts from R Scripts

asciicast 2.3.1

New show argument in write_svg() to show the SVG on the screen. It is TRUE by default in RStudio.
play() now show the output in the viewer pane in RStudio.

asciicast 2.3.0

record() has a new argument: show_output, to show the output from the subprocess in real time.
New SVG theme: readme, to be used in README.Rmd (and similar) files on GitHub. It generates two SVG files, one for light and one for dark mode, and creates a README.md file that automatically uses the correct one when viewed on GitHub.
New SVG theme: github-dark.

asciicast 2.2.1

New expect_snapshot_r_process() function to run a testthat snapshot test in an asciicast subprocess.
On Windows asciicast does not error if the patch version of the current R version is different from the one asciiast was built with. This happens often when installing asciicast from binaries, and these R versions should be fully compatible.

asciicast 2.2.0

write_html() now supports ANSI hyperlinks.
Much better parameterization of asciicast in knitr. You can now set asciicast parameters via chunk options. Relatedly, the init_knitr_engine() does not have an options argument any more. Set knitr chunk options instead. See the README.Rmd file of the package or the included github-readme.Rmd for examples.
HTML output now works better in roxygen2/Rd.
init_knitr_engine() has an interactive argument now, to allow non-interactive mode.
asciicast in knitr now caches HTML output much better.
asciicast now supports true color ANSI escapes in HTML output (#46).
If the asciicast_html_details option is set, then asciicast puts the HTML output in a <details> tag.
New interactive parameter of init_knitr_engine() allows recording in non-interactive R sessions. The default is (still) interactive = TRUE.

asciicast 2.1.0

The new write_html() function can create a themed HTML snapshot of an ascii cast. HTML otuput is now the default in pkgdown, for snapshots. For animations we still need to use SVG files.
asciicast can now record casts on R installations that do not have an R shared or static library.
SVG output now looks correct in Firefox with large fonts (#42).

asciicast 2.0.0

Completely new record() implementation that uses an embedded R interpreter in a subprocess. This means that asciicast can now record on Windows, and the recordings are of much faster and of higher quiality.

Another benefit is that simulated typing does not happen in real time, but recordings are as fast as the script itself, and the simulated typing (if requested) is added after the recording.

It is also possible to record R scripts that are not valid R code. (These will fail of course, but sometimes that's what you want to show.)

record() does not set the error option in the asciicast subprocess any more, but the output of errors is simply recorded.

New record_output() which returns the recorded output as a character vector instead of an asciic cast.
Adding a #' to a line omits the simulated typing for that line and the line will appear in one step.
New write_gif() function to save a cast as a GIF. It needs phantom.js currently.
SVG output can have themes now. The package comes with a bunch of predefined themes, or you can create your own. See default_theme().
knitr options are set temporarily now, and they are restored after the knitr run.
The asciinema_player() HTML widget now properly sets the height and width of the player window, using the height and width parameters of the cast.
record() now works with script files that end with a comment line (#13).
The initial R prompt is now not left out when recording a cast.
asciinema_player() now creates an HTML widget that works well on Firefox as well.
asciicast is properly tested now, so it should be much more stable.
