How to call latexmk in emacs, and jump to next-error
auctex, build-process, emacs, latex, latexmk
Solution
Sorry I don't have the ability to comment, or I would just add this as a comment. Chris Conway's answer works, except that it should use `TeX-run-TeX` instead of `TeX-run-command` so that AucTeX knows to process the error messages.
(add-hook 'LaTeX-mode-hook (lambda ()
(push
'("Latexmk" "latexmk -pdf %s" TeX-run-TeX nil t
:help "Run Latexmk on file")
TeX-command-list)))
It might also be wise to add something like
'("%(-PDF)"
(lambda ()
(if (and (not TeX-Omega-mode)
(or TeX-PDF-mode TeX-DVI-via-PDFTeX))
"-pdf" "")))
to `TeX-expand-list` and use `"latexmk %(-PDF) %s"` so that it will work in both pdf and dvi mode. Personally, I find it easier to use customize especially when you are experimenting.
Problem
I would like to use latexmk to compile my LaTeX documents in Emacs. Especially I need the Emacs functionality `next-error`, which is typically called with C-x `, and jumps to the next LaTeX error in the document. I would like to call `latexmk` either using `C-x compile` or the AUCTeX `C-c C-c`. First, I set `latexmk` to use ``` $pdflatex = 'pdflatex -interaction=nonstopmode'; ``` Option 1: C-x compile I press `C-x compile` and type `latexmk -pdf foo`, which runs `pdflatex`. But `next-error` will not jump to the errors, even if the *compilation* buffer contains errors: ``` ! Paragraph ended before \author was complete. <to be read again> \par l.48 [...] Compilation exited abnormally with code 12 ``` How can I automatically jump to this error in line 48? Note that this question of parsing the latex output has nothing to do with `latexmk` directly. The same problem occurs when I just do `C-x compile pdflatex -interaction=nonstopmode foo`. Option 2: AUCTeX How can I set AUCTeX to call `latexmk -pdf` instead of `pdflatex` on my .tex file? Of course, I want `next-error` to work here too. UPDATE: I started a bounty because if this worked it would be a great tool for many people. I consider the question answered if a solution is given that lets me easily compile my LaTeX document using `latexmk` in Emacs and jump to the errors using `next-error` (of course, the errors might be in included .tex files, not necessarily in the master file or the current buffer). UPDATE: Thanks to Ivan (and Chris) for making AUCTeX+Latexmk work. In the meantime, I found that using Rubber to compile LaTeX is also an excellent choice. It will display error messages in the format used by `gcc` and other compilers, so it naturally works with Emacs `C-x compile`, e.g. `C-x compile rubber --pdf foo`, and the error messages are parsed correctly.
