After compiling TXS (HG 9c57ed), all sorts of problems popped up. Some have already been reported in the bugs section, but here is another. If you click on say view pdf, you will get an error saying:
Error: One command expansion invalid.
This is on El Capitan.
Which command are you using for view pdf? Internal or external viewer?
Post the output of Help / Check Latex Installation (at least the lines containing something with pdf)
I did do a removal and then a reinstall of MacTeX, if it means anything and all was working prior to the latest commit. Here is what I have after agreeing to the reccomendations (as a result of El Capitan).
Under build & view (when I choose this option, it compiles but does not bring up the resulting pdf):
txs:///pdflatex | txs:///view-pdf
Under default viewer:
txs:///view-pdf
Under PDF viewer
txs:///view-pdf-internal --embedded
Please try the most recent version from the repository hg 5590 (d5117a0e3bc3) or newer. It includes a possibly related bugfix as well as a more detailed error message for command expansion problems.
I just did and I get
Error: One command expansion invalid.
Parent Command: txs:///view-pdf-internal --embedded
Primary Command: view
Sorry, I left some testing code with my last commit that always produced the error message. Please update and try again.
I updated it. Now the buttons and commands seem to work now as before. Thank you!
