R path not working: S{userHome}\scoop\apps\r\current\bin\R.exe

[mathiasleroy]

I have R installed with scoop and everything works fine with the R extension.
the rpath in settings is:

"r.rpath.windows": "${userHome}\\scoop\\apps\\r\\current\\bin\\R.exe",

and this path is totally correct,
proof of that is that works with R extension: I can run R files with ctrl+enter or ctrl+shift+s to run code in the terminal.

But with R debugger i get this error:

R path not working:
S{userHome}\scoop\apps\r\current\bin\R.exe
(Can be changed in setting r.rpath.XXX)

I tried replacing \\ with / and also tried

"r.rpath.windows": "${env:USERPROFILE}\\scoop\\apps\\r\\current\\bin\\R.exe",

is the issue from ${userHome}?
or can someone confirm that this variable works?

this could be duplicate of #155, but i had the impression it was slightly different.

EDIT: I can't use absolute path because my vscode settings are synced on different machines.

By default, settings entries do not resolve ${...} variables. The ones that do are the exception and their behavior depends on the extension/program part using them, see also here. This situation is made a bit more complicated by the fact that the R-Debugger extension uses the same config entry as the vscode-R extension (r.rpath.xxx), but the internal handling of the setting value is different. At some point, resolution of selected ${...} variables was introduced in vscode-R, but not the debugger extension (REditorSupport/vscode-R#1444).

I'll have a look at how things are handled in vscode-R and try to get the same behavior in the debugger extension. In the long-term it might also be useful to add an entry to the debug config that allows overwriting the R path to be used for the debug session.

The issue should be fixed with v0.5.6.

It is now possible to specify an R path in the launch config. If none is specified (the default), the settings entry is used. This replacement is done before variable substitution, so all variables from the reference are supported here. Note that vscode-R still supports only the ones mentioned explicitly in the config description.
