Vim is a powerful text editor that many developers and programmers rely on for efficient coding and file management. One of the popular plugins that enhance the Vim experience is NERDTree, which provides a tree-like file navigator. In many situations, it can be beneficial to synchronize the NERDTree file tree with the terminal pane in Vim, so you can seamlessly navigate your files and execute commands without losing your context.
The Problem Scenario
Users often want to have their NERDTree plugin in Vim reflect the current working directory of the terminal pane. When you open a terminal pane and change directories, you may want the NERDTree window to automatically update to show the new working directory. The original code that some users might try to use could look something like this:
" Original Code
autocmd BufEnter * if &ft ==# 'nerdtree' | silent! execute 'NERDTreeFind' | endif
However, this code might not work as expected, leading to confusion.
How to Synchronize NERDTree with Terminal Pane
To effectively synchronize NERDTree with the terminal pane in Vim, you can use the following approach:
- Create an autocommand: This will trigger every time you change the working directory in the terminal.
- Update NERDTree: Use the
NERDTreeFind
command to refresh the NERDTree view to the current directory.
Here’s a cleaner way to achieve synchronization:
" Improved Code for Synchronizing NERDTree with Terminal
function! SyncNERDTree()
if !empty(expand('%:p:h')) && exists('t:NERDTree')
execute 'NERDTreeFind'
endif
endfunction
autocmd BufEnter * call SyncNERDTree()
Analyzing the Code
- The
SyncNERDTree
function checks if the current buffer is not empty and that the NERDTree window exists. - If both conditions are met, it calls the
NERDTreeFind
command, which updates the NERDTree view to reflect the currently opened file’s directory.
This solution ensures that every time you switch buffers or edit files, your NERDTree pane will automatically update, keeping your workflow efficient.
Practical Examples
Suppose you are working on a project with multiple directories. You can open a terminal pane in Vim and navigate to different directories:
cd src
After executing this command, if you have implemented the autocommand above, switching to your NERDTree window will now show files from the src
directory, allowing you to maintain context without manual updates.
Why This Matters
By synchronizing NERDTree with the terminal pane, you improve your workflow and efficiency. This capability is especially useful for developers working on large projects with multiple components, as it minimizes the need for repeated manual updates. It also helps reduce the risk of opening files from the wrong directory, which can lead to errors and wasted time.

Conclusion
Synchronizing NERDTree with the terminal pane in Vim is a practical way to enhance your coding experience. With a simple autocommand, you can maintain an organized and efficient workflow, allowing you to focus on development rather than file management. Experiment with the provided code, and consider adjusting it to fit your specific workflow needs. Happy coding!
