RStudio Addin to Run a Selection as a Background Job

RStudio daily release now includes a Jobs pane. See this excellent demo from @hrbrmstr for details.

This allows one to source a script as a background job. But what about incidental code? This Addin allows one to highlight a region of code to be run as a background job.

Installation

You can install the development version of dash from GitHub or GitLab

devtools::install_github("jonocarroll/dash")
devtools::install_gitlab("jonocarroll/dash")

NOTES

• dash hastily pre-empts any official implementation, and as such will be rendered useless once that is complete.
• dash has been tested with RStudio 1.2.719. The API is under constant development and as such this could break at any daily release. I will try to keep up as best as I can. The internals became available as PR #2923 was merged, which means the earliest daily this should be compatible with is probably

Filename	Published	Commit	Build ID
rstudio-1.2.712-amd64.deb	2018-06-08 20:22:28	87458be9	da7b43c700e714272546b76297fc64a8-12

• There doesn't appear to be an exported way to STOP a job, so keep an eye on your infinite loops.
• dash writes the selection as a temporary file and sources that, so the selected code must be valid.
• Obviously requires a fairly recent version of RStudio.
• install_gitlab requires the development version of r-lib/devtools.

dash's Issues

runScriptJob error

Hi Jonathan,

nice idea! I tried it on RStudio Server Pro and locally.

Here's what I get:

RStudio Server Pro (1.2.713) (Debian 9)

Fehler in .Call("rs_runScriptJob", path, encoding, workingDir, importEnv,  : 
  Falsche Anzahl von Argumenten (5), erwarte 4 für 'rs_runScriptJob'

Local (1.2.679) (Arch)

Error in .rs.api.runScriptJob(path = path.expand(tf), workingDir = getwd(),  : 
  could not find function ".rs.api.runScriptJob"
