For example, you search from the current cursor position the beginning
of foobar and want to write until the next baz. You can simply do this:
/^foobar/+,/^baz/-w foobar.txt
This copies the text between the lines to the file foobar.txt If you
want to include the start and end patterns, leave the + and - signs out.
Christian gives a workable solution for a certain line-format,
assuming your search-items are on their own lines, and the
contents between them are also on their own line(s).
It gets a little trickier when you have them inline:
aaaacgtaggggggatgca
^^^^^^^^
if you want to extract the information between "acgt" and "tgca"
(in the above example "agggggga"), you'd have to pull the text in
visual mode, and use search-offsets
:nnoremap <f4> /acgt/e+1<cr>v/tgca/s-1<cr>y:new<cr>P
would map <f4> to
/acgt/e+1 " search for 'acgt' and position the cursor
" at the end+1 of the match
<cr> " execute the search
v " go into character-wise visual mode
/tgca/s-1 " search for 'tgca' and position the cursor
" at start-1 (the character before the match)
<cr> " execute the search
y " yank the resulting text
:new<cr> " create a new unnamed buffer
P " paste the yanked text in this new buffer
You can then save this new buffer as you would any other:
:w /path/to/wherever/extract.txt
It gets a little trickier if you want to have it mapped *and*
provide the patterns dynamically, but it can be done:
:let b:start = "acgt"
:let b:end = "tgca"
:nnoremap <f4>
/<c-r>=b:start<cr>/e+1<cr>v/<c-r>=b:end<cr>/s-1<cr>y:new<cr>P
should come fairly close. That way, you could tweak the values
for b:start and b:end and <f4> should Do The Right Thing(tm).
To read up on some of these bits:
:help /
:help {offset}
:help c_CTRL-R_=
Hope this helps,
