Select Opened File in NERDTree

Prerequisites

This is a plugin that works with NERDTree, if you don't have it already, please install it first.

Install

Use the same installation method as you use for other NERDTree plugin. Here is mine with vim-plug:

Plug "kezhenxu94/nerdtree-select-opened-file.vim"

Save it, and install it with :PlugInstall.

Usage

This plugin provides a new command NERDTreeSelectOpenedFile, which you can use directly in an open file, or you can map it to a key binding:

nnoremap <silent> <leader>1 :NERDTreeSelectOpenedFile<CR>

More

This plugin is inspired by the project explorer in some moreden IDEs, such as JetBrains IDE products, and mimics most of the behaviours in those IDEs:

• If the NERDTree is not opened, it will be opened automatically.
• If the NERDTree is opened, but not focused, it will be focused automatically.
• If the NERDTree is opened and focused, it will be closed automatically.
• If the current file is not inside the NERDTree's root directory, nothing is selected, instead, the NERDTree is opened and focused.
