# Clean .bbl files with latexmk -C

I use TeXLive 2012 and compile with run

latexmk -pvc -pdf -quiet test.tex

later I clean the directory with

latexmk -C

But test.bbl remains. How can I help latexmk to find bbl files?

### test.bbl (first lines)

% \$ biblatex auxiliary file \$
% \$ biblatex bbl format version 2.1 \$
% Do not modify the above lines!
%
% This is an auxiliary file used by the 'biblatex' package.
% This file may safely be deleted. It will be recreated by
% biber as required.

You need the .bbl file for typesetting the document! –  egreg Nov 19 '12 at 14:27
...I thought latexmk creates it. I never wrote a .bbl file manually. –  Jonas Stein Nov 19 '12 at 15:30
If your document is in final form and you don't need to compile it any more, then you can safely delete the .bbl file. –  egreg Nov 19 '12 at 16:52
as long I do not delete it manually with rm latexmk ignores changes I made with jabref. –  Jonas Stein Nov 19 '12 at 17:35

By default, latexmk treats .bbl files as non-regeneratable. This is because the .bib from which they are made is not always available. See the documentation for a fuller explanation, especially the explanation of the \$bibtex_use variable. To get latexmk -C to delete .bbl files, put the following in an initialization file:

\$bibtex_use = 2;

Oh my, you were faster than me by 10 seconds. :) In other news, I know that this is probably not the best place to say this, but your awesome work with latexmk inspired me to write arara. I really admire all the effort you've put into the tool. Thanks a million. –  Paulo Cereda Nov 19 '12 at 18:26
Is \$bibtex_use = 2; equivalent to -bibtex? –  Jonas Stein Nov 19 '12 at 18:34
Yes. The option -bibtex simply sets \$bibtex_use to 2. –  John Collins Nov 19 '12 at 22:29

Another option to the presumably canonical answer John gave is specifying \$clean_ext in a latexmkrc file, which contains your personalized global options. This file can be in one of the places I outlined in my answer to Latexmk: makeglossaries, Biber and pdfLaTeX / Where to put latexmkrc?. Also see the latexmk manual.

My complete list of extensions looks like this:

\$clean_ext = 'synctex.gz synctex.gz(busy) run.xml tex.bak bbl bcf fdb_latexmk run tdo %R-blx.bib'

(As a result of -- I think -- SyncTeX, latexmk, Texmaker, biblatex, Biber, todonotes)
