In my installation of TeXlive + TeXworks, it has latexmk, but I didn't like latexmk, because when only a single pdflatex is needed, it does some multiple runs. In addition, latexmk sometimes does not run multiple times, even when necessary, and latexmk is slower than pdflatex for a single run.
How can I configure a typeset menu that does simply pdflatex + bibtex + pdflatex + pdflatex?
Although your installation has latexmk, according to this link it is no longer packaged as part of TeXWorks as of r865. The reason given for this is that latemk is not available on all platforms.
To manually setup latexmk for use with TeXWorks see configure latexmk in Texworks 0.2.3.
If there are specific cases where you find that latexmk does more runs then necessary you should report those so that latemk can be enhanced to correct these.
pdflatexmost of the time, and just uselatexmkwhen you want to runbibtex? – Alan Munn Jul 06 '11 at 19:13latexmkis slower than the simplepdflatexeven for a single run. Even further, sometimes I needed to forcebibtex, when only bib file is modified. I can't make it re-happen now, but some weird cases happened. – Chang Jul 06 '11 at 19:26latexmkuseful in the last stages of document preparation, but not as my everyday typesetting script. Most of the time when you are recompiling a document you don't care much about resolved references etc. but more about whether the content is correct in other ways. Andlatexmkdoes seem to be slower overall. – Alan Munn Jul 06 '11 at 19:30pdflatex. – Peter Grill Oct 06 '11 at 03:21pdflatexand when needed use the script. – Chang Oct 06 '11 at 04:00
