Error linking GRASS on Arch Linux

[pat-s]

On Arch Linux with Grass 7.8 installed from AUR I get

link2GI::linkGRASS7(streets)
Error in gregexpr(pattern = "\"", root_dir)[[1]] : 
  subscript out of bounds

Same for

link2GI::searchGRASSX()
Error in gregexpr(pattern = "\"", root_dir)[[1]] : 
  subscript out of bounds

both with CRAN and dev version.

Even when specifying the full path I get the error

 link2GI::linkGRASS7(location = "/opt/grass/bin")
Error in gregexpr(pattern = "\"", root_dir)[[1]] : 
  subscript out of bounds

I was struggling with this a few weeks ago when I switched occasionally to Manjaro. Thought that I have fixed it thanks for reporting that I did not. The problem is that the GRASS people changed their initialisation script naming variables different and using other libs. Asap I will dive in again .

quite a sloppiness and inconsistency of mine I did the recent commits in the master branch...
Please check the master branch on github. If I do so I get for Manjaro Arch:
After solving #27 Iwill push it asap on CRAN either.

 link2GI::searchGRASSX()
     instDir version installation_type
1 /opt/grass   7.8.0           grass78

Thanks. This works now for, but link2GI::linkGRASS7() does not yet

searchGRASSX()
# A tibble: 1 x 3
  instDir    version installation_type
  <chr>      <chr>   <chr>            
1 /opt/grass 7.8.1   grass78    
      
link2GI::linkGRASS7()
Error in rgrass7::execGRASS("g.proj", flags = c("c", "quiet"), proj4 = proj4) : 
  object 'proj4' not found

still needs some checks
