Thank you Uwe. An updated patch (against 6db8a1a3) is here https://raw.githubusercontent.com/haji-ali/auctex/tex-build/etc/auctex-output-dir.patch This should hopefully fix the issue that was pointed out by Ikumi regarding the default command and C-c C-a. I also made sure to make `TeX-output-dir` local so that it can be controlled buffer-wise, so make sure to use setq-default instead of setq if you are changing this in your Emacs init file. I would appreciate any feedback or input on my implementation of the fix, below: The main problem that I ran against is that the function `TeX-command` accepts an argument `file-fn` which points to the function (usually TeX-master-file or TeX-region-file) that is supposed to return the filename. However, TeX-command then calls other functions like TeX-run-command with the *result* of this function without actually passing the function. This is problematic because these commands then infer filenames by appending extensions (like "pdf" or "idx"), instead of using the original function with this extension as I think they should (particularly for getting my patch to work). I am guessing that changing the arguments of these functions would be problematic because it would break existing user code. So I resolved this by introducing a new variable `TeX-command-file-function` which contains the value of file-fn when TeX-command is called. This is similar to TeX-command-sequence-file-function but I wasn't sure if I can use that variable instead of defining a new one. I also changed TeX-save-document to accept a file-function (as well as a string) as argument. If the argument is a file-function then the function is called to get the filename. Finally, I defined a new function called TeX-get-command-filename which gets the filename from `TeX-command-file-function` or the argument if these are callable, otherwise it simply returns the argument (possibly with an extension). Let me know if the patch works for you and if the implementation is agreeable. The remaining issues are in preview-latex which I will get to once the core functionality is implemented correctly. Best regards, -- Al
