ref

Ref is a lightweight command-line reference manager. It is built on python and vim.

Ref is released under the terms of the MIT license.

Installation

Preferred: Installation in dedicated conda environment

conda create -n ref
conda activate ref
conda install poppler vim ncurses -c conda-forge
git clone git@github.com:jzbontar/ref ref
cd ref
python setup.py develop

Replace the last line with python setup.py install if you don't want to change ref.

Prerequesites (manual)

You'll need a recent vim, compiled with python support.

On ubuntu the ones in apt-get will do, on Mac OS X use brew install vim which has python3 bindings. On Mac OS X you'll also need poppler for the pdftotext command line tool: brew install poppler

Installation (manual)

git clone https://github.com/jzbontar/ref.git
cd ref
python setup.py install

Configuration

Set your base_dir and google scholar Cookie in ~/.ref.conf, for example:

{
"base_dir"  : "~/Dropbox/ref",
"Cookie"    : "<<Obtained from request headers to google scholar, see below>>"
}

The database and pdf's will be saved in base_dir. Setting your base_dir to a dropbox folder will enable automatic syncing between your Dropbox-enabled computers.

Obtaining the cookie:

Go to scholar.google.com, search for something
On the search results, go to settings > Bibliography manager > Show links to import citations into BibTeX
In chrome, right click on page > Inspect > tab "Network" > click in list of html elements on page "scholar" > default tab "Headers" > section "Request Headers" > field "cookie"

Usage

Type "ref" on the command line to see the main screen which is a vim session with two panes, split horizontally. Move around like usual in vim with hjkl and jump between the panes with ctrl+W+W

:Add rel/path/to/downloaded/pdf will add the document and fetch the bibtex from google scholar based on the title from the document.
:Fetch if the fetched bibtex was wrong, fix the title then type :Fetch to try again.
Search by typing //keyword where the keyword could be an author name or words from the title.
To clear a search just enter // (i.e. search without any keyword)
You can still use vim's regular search with /keyword
Exit with q
ctrl+U toggles the U flag (U for Unread)
:Delete deletes document

Pro tips

If you're switching from another reference manager or just a messy folder of pdfs, you can open a python session, type import ref; ref.init() and ref.import_dir(/path/to/your/messy/folder)

The codebase consists of two files with less than 600LoC, it's easy to change things if needed.
