ADS to BibDesk ^{API edition} (ads2bibdesk)

ads2bibdesk helps you add astrophysics articles listed on NASA/ADS to your BibDesk database using the new ADS Developer API.

The program is loosely based on the original ads_bibdesk from J. Sick et al. However, the query is handled with a python client for the ADS API (ads, maintained by A. Casey). Obsolete codes are replaced in favor of newer built-in Python modules with a simplified code structure. The macOS workflow building process have been updated. The project packaging now follows the new PyPA guideline.

Due to the API usage, ads2bibdesk requires the user to specify a personal API key, per the new NASA/ADS policy. The instruction on how to obtain a key can be found on this official github repo: adsabs-dev-api. In short, to obtain access to the ADS Developer API, one must do two things:

• Create an account and log in to the latest version of the ADS
• Push the “Generate a new key” button under Customize Settings -> Account Settings -> API Token

The API key can be written into your ads2bibdesk preference file ~/.ads/ads2bibdesk.cfg (see the template). Following the Python/ads package's instruction, one can also save the key to ~/.ads/dev_key or as an environment variable named ADS_DEV_KEY.

Quickstart

Installation

The command line script can be installed via:

pip install --user git+https://github.com/r-xue/ads2bibdesk.git # from GitHub
pip install --user ads2bibdesk                                  # from PyPI (likely behind the GitHub version) 
pip install --user .                                            # from a local copy 

To build the macOS app and service workflow, you need to further run:

pip install --user -U --no-deps --force-reinstall --install-option="--service" ads2bibdesk     # from PyPI

The option "--service" will create two files Add to BibDesk.workflow and Add to BibDesk.app in ~/Downloads/. To install the service, click Add to BibDesk.workflow and it will be moved to ~/Library/Services/. For the app, just drag and drop it to any preferred location.

Note:

• Only Python >=3.7 is supported (see below).
• With the "--user" option, you must add the user-level bin directory (e.g., ~/Library/Python/3.X/bin) to your PATH environment variable in order to launch ads2bibdesk.
• Both the macOS service and app are based on the Automator workflow). They simply wrap around the command line program and serve as its shortcuts.
• The service shortcut will not work within some applications (e.g., Safari) on macOS >=10.14 due to new privacy and security features built in macOS (see this issue)

Usage

From the Command line

Add or update a new article from ADS:

ads2bibdesk "1807.04291"
ads2bibdesk "2018ApJ...864L..11X"
ads2bibdesk "2013ARA&A..51..105C"
ads2bibdesk "10.3847/2041-8213/aaf872"

ads2bibdesk accepts three kinds of article identifier at this moment

• ADS bibcode (e.g. 1998ApJ...500..525S, 2019arXiv190404507R)
• arXiv id (e.g. 0911.4956).
• doi (e.g. 10.3847/1538-4357/aafd37)

A full summary of ads2bibdesk commands is available via:

ads2bibdesk --help

From the macOS app

1. Copy the article identifider to the clipboard, in any application
2. launch Add to BibDesk.app

From the macOS service

1. Highligh and right-click on the article identifider
2. Choose 'Services > Add to Bibdesk' from the right-click menu

Compatibility and Dependency

• macOS (>=10.14)
• Python (>=3.7.3)
• BibDesk (>=1.7.1)

While the program likely works on slightly older software versions, I don't focus on the backward compatibility. On my working machine (Catalina), I set Python 3.8 from MacPorts as default:

sudo port install python38 py38-pip py38-ipython
sudo port select python python38
sudo port select ipython py38-ipython
sudo port select pip pip38

Status

The following functions have already been implemented in the package:

• query the article metadata (title, abstract, BibTeX, etc.) with the new API by article identifiers (no more in-house ADS/arxiv HTML parsing functions)
• download article PDFs using the ADS gateway links
• use an authorized on-campus ssh proxy machine (with your public key) to download PDFs behind the journal paywall
• add/update the BibDesk database and attach downloaded PDFs (largely borrowing the AppleScript method from the original ads_bibdesk)

Other changes from the original ads_bibdesk include:

• clean up the dependency requirements
• replace obsolete Python syntax/functions/modules with newer ones, e.g. optparser->argparser, f-string formatting, and use configparser()
• The macOS Automator workflow is running the installed console script rather than an embedded Python program

Some less-used features from the original ads_bibdesk are gone: notably, the "ingest" and "preprint-update" modes. But I plan to at least add back the "preprint-update" option, by scanning/updating article_bibcode associated with arXiv). My improvement proposal can be found here.
