caleb 0.6.1

A tool to automatically retrieve bibtex entries

caleb

caleb is a tool to automatically fill in your Latex citations.

Usage examples

See the examples directory along with the an_example.tex file. The following examples occur in the examples directory.

• First run pdflatex an_example.tex to generate an_example.aux. caleb will now parse an_example.aux to generate the appropriate bibliography file.

caleb an_example

• The first important commandline option is --take-first. When making a query, it is possible that there are multiple result. By default, caleb will take no action here. However, if the --take-first flag is passed, caleb will take the first entry.

caleb --take-first an_example

• The next important commandline option is --method. By default, caleb uses crossref.org. However, we can also tell caleb to use https://mathscinet.ams.org/mrlookup.

caleb --method ams

Workflow integration

latexmk

• The best way is probably to integrate into latexmk. The -pdflatex flag allows us to run caleb after each pdflatex call.

latexmk -pdf -pdflatex='pdflatex %O %S; caleb -t -m ams %B' an_example

• We can set the -pdflatex flag in a .latexmkrc file. This can either go in the your tex project folder or in the home directory. So in the .latexmkrc file, include the following line (see examples directory for an example):

$pdflatex='pdflatex %O %S; caleb %B'

Barebones

• The barebone approach is to run caleb before running bibtex.

pdflatex an_example
caleb an_example
bibtex an_example
pdflatex an_example
pdflatex an_example

cocalc

http://cocalc.com contains a collaborative latex editor that allows you to use a custom build command. We can use caleb by changing it to

latexmk -pdf -pdflatex='pdflatex %O %S; caleb -t -m ams %B' -f -g -bibtex -synctex=1 -interaction=nonstopmode an_example.tex
