I use both the PC-based [g]vim and cygwin's [g]vim. There are many times when
I need the behaviour of PC vim, but I also want to bang out to bash. With help
from this forum and much trial and error, I found that the following is a
robust way to allow this:
let &shell='set HOME=c:\cygwin\home\' . $USERNAME .
\ '& c:\cygwin\bin\bash.exe -i'
This fails when I bang out to unix's arithmetic interpreter 'bc' from files
that have ff=dos, which applies to most file that I work on. I simply set
ff=unix temporarily. I can avoid this by writing a wrapper around bc or bash
(not that I will find the time to robustify such a solution any time soon), but
I was wondering if there is a simpler way to do this? I tried the following,
but it generates "E485: Can't read file
c:/Users/$USER/AppDAta/Local/Temp/1/VIoEED3.tmp".
let &shell='set HOME=c:\cygwin\home\' . $USERNAME .
\ '& C:\cygwin\bin\dos2unixe.exe | ' .
\ c:\cygwin\bin\bash.exe -i'
