Hello,
I am trying to capture the stdout (a simple digit) from a python script that I
am calling from vim and assign it to a variable. I have been trying redir but
can't seem to get it to work.
Any help would be appreciated!
Thanks.
Simon.
Many thanks for the many answers, unfortunately I am still struggling.
The python script ends with:
sys.stdout.write(refs[int(chosen[1])][0])
When I run the script with %!nameofscript the correct answer is replaces the
content of the current buffer. I still can't seem able to pipe it into a
variable. Could it be because the python script gets user input from a dialog
box that they have to select by pressing Enter?
Thanks again for all your assistance.
Simon.
%!nameofscript runs the script as a filter, i.e., its output replaces
the current buffer. This is intentional: for instance :2,$-1!sort uses
the external "sort" program to sort all lines of the current buffer
except the first and last. (It feeds lines 2 to $-1 to the stdin of
sort, and replaces them with its stdout.)
Use instead
:update | let variablename = system('nameofscript < ' .
shellescape(expand('%'),1))
Or if your script doesn't require to get your editfile as input, just use
:let variablename = system('nameofscript')
Or if your script can get its data from vim.current.range (after
importing vim), then
:redir => variablename
:%pyfile nameofscript
:redir END
Best regards,
Tony.
