|
" Overview
|
|
" --------
|
|
" You can use the scratch plugin to create a temporary scratch buffer to store
|
|
" and edit text that will be discarded when you quit/exit vim. The contents
|
|
" of the scratch buffer are not saved/stored in a file.
|
|
"
|
|
" Installation
|
|
" ------------
|
|
" 1. Copy the scratch.vim plugin to the $HOME/.vim/plugin directory. Refer to
|
|
" the following Vim help topics for more information about Vim plugins:
|
|
"
|
|
" :help add-plugin
|
|
" :help add-global-plugin
|
|
" :help runtimepath
|
|
"
|
|
" 2. Restart Vim.
|
|
"
|
|
" Usage
|
|
" -----
|
|
" You can use the following command to open/edit the scratch buffer:
|
|
"
|
|
" :Scratch
|
|
"
|
|
" To open the scratch buffer in a new split window, use the following command:
|
|
"
|
|
" :Sscratch
|
|
"
|
|
" When you close the scratch buffer window, the buffer will retain the
|
|
" contents. You can again edit the scratch buffer by openeing it using one of
|
|
" the above commands. There is no need to save the scatch buffer.
|
|
"
|
|
" When you quit/exit Vim, the contents of the scratch buffer will be lost.
|
|
" You will not be prompted to save the contents of the modified scratch
|
|
" buffer.
|
|
"
|
|
" You can have only one scratch buffer open in a single Vim instance. If the
|
|
" current buffer has unsaved modifications, then the scratch buffer will be
|
|
" opened in a new window
|
|
"
