SPIRES script is a command line program written in Python that accesses information on papers in the SPIRES online high energy physics literature database. It can access title, author and BiBTeX records and update your local BiBTeX database and/or a local HTML record of the papers you have.

installation on a GNU/Linux system

The script requires the python interpreter and wget to be installed on your system. These are automatically installed on most GNU/Linux distributions, but check they are there by typing 

python

and 

wget

at the command line and see what happens.

If python and wget are present copy the script into a text file with a name such as spires.py.

To run it type 

python spires.py hep-th/9711200

usage

The typical accepted inputs are the usual arXiv references or a SPIRES-style journal reference 

python spires.py hep-th/9711200
python spires.py 0705.0303
python spires.py CMPHA,43,199

If no options are specified all possible outputs will be displayed 

tom@fyodor:~$ python spires.py hep-th/9711200
@Article{Maldacena:1997re,
     author    = "Maldacena, Juan M.",
     title     = "The large N limit of superconformal field theories and
                  supergravity",
     journal   = "Adv. Theor. Math. Phys.",
     volume    = "2",
     year      = "1998",
     pages     = "231-252",
     eprint    = "hep-th/9711200",
     SLACcitation  = "%%CITATION = HEP-TH/9711200;%%"
}
\cite{Maldacena:1997re}
Maldacena, Juan M.
The large N limit of superconformal field theories and supergravity
<p><a href="http://arxiv.org/abs/hep-th/9711200">The large N limit of superconformal field theories and supergravity</a> by Maldacena, Juan M. (hep-th/9711200)</p>

To see all the options access the help page 

tom@fyodor:~$ python spires.py -h
SPIRES script
Usage:
python spires.py reference [ -hatbcevd ] [ --library library.bib ] [ --database database.html ]
"reference" must be a standard arXiv reference, e.g. hep-th/9711200 or 0705.0303, or a SPIRES journal reference, e.g. CMPHA,43,199
Options:
-h, --help
displays this help message
-a
displays the author(s)
-t
displays the title
-b
displays the BiBTeX entry
-c
displays the LaTeX citation
-e
displays everything
-v
verbose mode
-d
displays an HTML database entry
--library library.bib
if it is not already in library.bib, appends the BiBTeX entry to library.bib
--database database.html
if it is not already in database.html, appends the HTML database entry to database.html

Each item can be specified individually with switches, e.g. -t for title, -a for authors, -b for BiBTeX entry, -c for LaTeX citation, -d for HTML database entry. For example 

tom@fyodor:~$ python spires.py hep-th/9711200 -at
Maldacena, Juan M.
The large N limit of superconformal field theories and supergravity

If you have a BiBTeX database file such as library.bib then the script can update the file with the BiBTeX entry if it is not already present 

python spires.py hep-th/9711200 --library library.bib

If you keep an HTML list of papers in database.html then the script can update the file 

python spires.py hep-th/9711200 --database database.html

future features

  • It would be good to have an option to download eprints from the arXiv. Unfortunately the arXiv blocks wget downloads and there doesn't seem to be a way around this.
  • Battle-hardening for error handling.

comments and bugs

If you have any comments or find bugs, please contact Tom.
