If, when you run a forward sync, you get a message which reads There's already a unique Okular instance running. This also means that you can only have a single PDF document opened by LaTeXTools at a time. If it is not, each forward sync command will open a new copy of the PDF. For forward sync to work properly, the PDF document must be opened in Okular's unique session. Forward sync (i.e., from Sublime to Okular) should work out of the box, but a caveat needs to be observed. The Okular viewer is quite similar to the Evince viewer. Additional viewers can be suppored use the Command Viewer. However, LaTeXTools offers support for both Okular and Zathura.
If the bring_evince_forward setting in the viewer_settings block is set to true and keep_focus remains set to true, Evince will first be brought to the foreground and then focus will be returned ST.Įvince is the default viewer since Gnome appears to be the most widely-used Linux desktop. In particular, you will need to ensure that your system Python install has the bindings for dbus and one or both of python-gobject or python-gi (the Python Gnome interface). On most installs that include the Gnome Desktop, it should work out of the box, but some distributions do not install some of the needed files. EvinceĮvince is the default viewer on Linux. Nevertheless, if you want to avoid installing another PDF viewer, this may be an acceptable option. Please note that Preview.app does not support forward or inverse sync, so you will not have that functionality available. It simply launches Preview.app with the relevant PDF file. The Preview.app viewer is very straight-forward. LaTeXTools also has some support for Preview.app and the Command Viewer can be used to add support for other viewers. Skim is currently the only widely-available PDF viewer for macOS that supports forward and inverse sync. Because of some issues with forward sync in 1.4.26, we recommend using 1.4.24.
This is the default viewer on macOS and should work out of the box.
Note, however, that Adobe's PDF viewer is not a good option to use while editing TeX documents, as it locks the PDF so that if you try to build the TeX document while Adobe has the PDF open, the PDF will not be updated and the build will fail. If you want to use a different PDF viewer, please see the Command Viewer described below. Sumatra is currently the only widely-available PDF viewer for Windows that supports forward and inverse sync. See the Windows platform settings documentation for more. If you installed a portable version that is not available on the system-wide PATH, you may need to update the sumatra setting to point to the appropriate executable. This is the default viewer on Windows and should work out of the box, assuming that it is installed on your system.
