Hello Vim List,
I wrote a command to perform :helpgrep on just the
distribution help files. My first pass was:
command! -nargs=1 HG sil RTPtemp
\ | exe 'helpg <args>'
\ | sil RTPrestore
RTPtemp and RTPrestore are commands taking no args (they are
defined below my sig).
To get this to work, I had to enclose 'sil RTPtemp' in an
'exe':
command! -nargs=1 HG exe 'sil RTPtemp'
\ | exe 'helpg <args>'
\ | sil RTPrestore
Why?
RTPtemp is defined without -bar. Therefore
:sil RTPtemp | exe 'helpg <args>' | sil RTPrestore
is invalid.
But if it were defined with -bar, the whole text would be seen as
argument of the first ":silent". You need ":exe" to terminate the first
":silent" before ":exe 'helpg <args>'".
Best regards,
Tony.
