## Vim-Dropbox
2+
3+
This is a fork of the [NetRw](https://github.com/vim-scripts/netrw.vim) project
4+
which allows vim to support URL's of the type `dbx:///Path/Inside/Dropbox`.
5+
6+
At the moment, it supports only reading files, creating files, and browsing
7+
directories. It cannot perform file deletions or renames.
8+
9+
## Installation
10+
11+
Installation is currently manual, but should not be too difficult for users
12+
versed in the ways of the shell.
13+
14+
1. Install the [Dropbox Python
15+
SDK](https://github.com/dropbox/dropbox-sdk-python) if you do not already
16+
have it installed.
17+
18+
2. Go to https://www.dropbox.com/developers/apps and create a new app with any
19+
name.
20+
21+
3. Click into the App's settings page and click on the `Generate` button under
22+
the label `Generated Access Token`.
23+
24+
4. Copy this token and replace the string `INSERT_TOKEN_HERE` in the file `bin/dbx.py` with the token.
25+
26+
5. Run the `make install` from this directory, which will simply append a line
27+
to your `.vimrc` and `.bashrc` files to enable this plugin.
28+
29+
If you run into any trouble with these steps, please open an issue on GitHub or contact the author out-of-band.
30+
31+
## Usage
32+
33+
vim dbx:///
34+
vim dbx:///TestFolder/Example.txt
