4. Hacking the NERD tree *NERDTreeHacking*
951951

952-
Public functions ~
953-
954-
The script provides 2 public functions for your hacking pleasure. Their
955-
signatures are: >
956-
function! NERDTreeGetCurrentNode()
957-
function! NERDTreeGetCurrentPath()
958-
<
959-
The first returns the node object that the cursor is currently on, while the
960-
second returns the corresponding path object.
961-
962-
This is probably a good time to mention that the script implements prototype
963-
style OO. To see the functions that each class provides you can read look at
964-
the code.
965-
966-
Use the node objects to manipulate the structure of the tree. Use the path
967-
objects to access the files/directories the tree nodes represent.
968-
969-
The NERD tree filetype ~
970-
971-
NERD tree buffers have a filetype of "nerdtree". You can use this to hack the
972-
NERD tree via autocommands (on |FileType|) or via an ftplugin.
973-
974-
For example, putting this code in ~/.vim/ftplugin/nerdtree.vim would override
975-
the o mapping, making it open the selected node in a new gvim instance. >
976-
977-
nnoremap <silent> <buffer> o :call <sid>openInNewVimInstance()<cr>
978-
function! s:openInNewVimInstance()
979-
let p = NERDTreeGetCurrentPath()
980-
if p != {}
981-
silent exec "!gvim " . p.strForOS(1) . "&"
982-
endif
983-
endfunction
984-
<
985-
This way you can add new mappings or :commands or override any existing
986-
mapping.
