In jennybc/reprex: Prepare Reproducible Example Code via the Clipboard
Running an external process on Windows
Figuring out how to write RTF to the Windows clipboard made me think
more about the functions system(), system2(), and (Windows only)
shell().
Here’s the highlight call used in reprex_rtf(), which converts such a
.R file into RTF:
highlight -i foo_reprex.R --out-format rtf --no-trailing-nl --encoding=UTF-8 --style darkbone --font 'Courier Regular' --font-size 50 -o gamma_reprex.rtf
There are many ways to invoke this from R:
system(): Docs say “not recommended for new code”.system2(): Officially, the “right” thing to use, at least on
*nix.shell(): Exists only on Windows. Explicitly runs cmd under a
shell, which is not the case for system() or system2() on
Windows.processx::run()
system() and system2() only differ with respect to how the
ultimately-run command is constructed. system2() is recommended for
new code and takes care of some fiddly details, e.g. quoting. However,
due to quoting nightmares, there are calls that can only be formed by
system() and some that can’t be formed at all (which is one of the
reasons processx exists). The main thing to know is that on Windows
command is executed directly, not within a shell, such as cmd.exe or
powershell.exe.
This is easiest to see in an example. dir is a command built into
cmd.exe. It will work inside shell() but not within system() or
system2().
shell("dir", intern = TRUE)

How did this come up? Depending on how you have installed highlight, the
system() and shell() calls below might produce different results.
Specifically, the system() call is reported to fail here if highlight
was installed via scoop, which uses a shim-based method of putting
things it installs on the PATH. This may additionally have something
to do with Windows short paths (?).
system("highlight --version")
#> [1] 0
shell("highlight --version")
Sys.which("highlight")
#> highlight
#> "C:\\PROGRA~1\\HIGHLI~1\\HIGHLI~2.EXE"
In any case, my current hypothesis is that I should invoke highlight via
shell() on Windows, to be more resilient to the different ways users
may have installed highlight.
Let’s prove I can invoke highlight in several ways by implementing
reprex_rtf() “by hand”. First, we render a reprex to the “r” venue and
explicitly write a local output file.
library(reprex)
reprex_r(sample(LETTERS, 5), outfile = here::here("internal/gamma"))
#> Non-interactive session, setting `html_preview = FALSE`.
#> Preparing reprex as .R file:
#> * C:/Users/jenny/Desktop/reprex/internal/gamma_reprex.R
#> Rendering reprex...
#> Writing reprex file:
#> * C:/Users/jenny/Desktop/reprex/internal/gamma_reprex_rendered.R
The output of this gamma_reprex_rendered.R is the input for the next
step, which is to form RTF.
More objects and helpers we’ll use:
r_file <- here::here("internal/gamma_reprex_rendered.R")
rtf_file <- here::here("internal/gamma_reprex_rendered.rtf")
system()
(cmd <- glue::glue("

Running an external process on Windows
Figuring out how to write RTF to the Windows clipboard made me think
more about the functions system(), system2(), and (Windows only)
shell().
Here’s the highlight call used in reprex_rtf(), which converts such a
.R file into RTF:
highlight -i foo_reprex.R --out-format rtf --no-trailing-nl --encoding=UTF-8 --style darkbone --font 'Courier Regular' --font-size 50 -o gamma_reprex.rtf
There are many ways to invoke this from R:

system() and system2() only differ with respect to how the
