I'm using Texify plugin for Pycharm to write latex. After running, I have to go manually to "out" folder and open it with Adobe. How to make Pycharm do that automatically?
Adobe locking the pdf file is a well-known issue, and so Adobe is not supported by TeXiFy. Depending on which OS you are on, the following pdf viewers are supported (links to TeXiFy wiki pages):
where supported means that the pdf automatically opens on compilation and that forward and backward search should work, the latter possibly after some configuration.
When you want to use some other pdf viewer, make sure that it does not lock the pdf file (so Adobe is not possible) and enter the command you would use to open the viewer from the command line in the Select custom pdf viewer command
field. This should work on (at least) most Linux and Mac distributions.
Edit As of TeXiFy b0.7.4 the internal PDF viewer is supported through the PDF viewer plugin.
