Pass the "noraise" flag to okular if it is used as a Latex viewer. If an
okular instance is already displaying the Latex compilation result,
subsequent invocations won't make okular steal focus from Emacs.
The Skim.app `displayline` command takes the flag `-g` which is "Do not bring Skim to the foreground"
when viewing the pdf results of the latex build, bringing skim to the foreground saves an `Alt+Tab` to open the app that I was intending to lauch by the auctex View command.
Previously, the last viewer set in `+latex-viewers` would take
precedence. The list is now reversed before applying changes so that the
first set has precedence.
The wrong hook variable was used to revert view buffers after compilation.
This incorrectly reversed the priority ordering of +latex-viewers. This
is an artifact from a rejected approach at short-circuiting
+latex-viewer, which was replaced with cl-block->cl-return.
Reported by @UndeadKernel
The +zathura, +skim, +okular and +pdf-tools module flags have been
removed in favor of +latex-viewers, which takes a list of symbols. Its
order determines the priority. The first viewer found on your system is
used.
If none of these viewers are found, it will fall back to
latex-preview-pane.
