Hi all,
I am trying to write an "extract method" function like this:
vmap <leader>e :call ExtractSub()<cr>
function! ExtractSub() range " yank selection into x "normal gv"xy let code
= shellescape(join(getline(a:firstline, a:lastline),"\n")) let subname =
input("Sub name: ") " put extracted sub/method into the x register let @x =
system("~/bin/extract --subname=" . subname.' '.code) " re-select and delete
normal gvd " paste x into visual areaq normal "xP endfunction
The idea is that I select a few lines of code in visual mode, pass them to my
/bin/extract code and have it rewrite my code.
Originally I had this:
vmap <leader>e :!~/bin/extract <cr>
That worked fine, but I read the selected code from STDIN. I can't figure out
how to do that with a function, so I resorted to trying to pass it on the
command line. That led to some garbled code (I have a bunch of \\ at the end of
lines). Is there a way I can still have /bin/extract reading from STDIN in the
function?
Cheers,
Ovid
