[Tex/LaTex] Inverse search with Emacs/AucTeX and SumatraPDF [on Windows 10]

auctexemacsforward-inverse-searchsumatrapdf

I've been trying to use Emacs/AucTeX along with SumatraPDF to view my output. In particular, I would like to make the forward and inverse search work. I use Windows 10.

Problem

Every time I double click something in my pdf output, a new instance (or a new window) of Emacs opens. Once at least one instance has .tex file opened, the following instances give the following message:

Warning: desktop file appears to be in use by PID 5132.
Using it may cause conflicts. Use it anyway? (y or n)

Regardless of my decision (y/n), I get new instances of Emacs with my .tex file open after every subsequent double click in my pdf output file.

I believe I should be redirected to a proper place in an opened .tex file in Emacs instead.

My current configuration

Here's what I added to my .emacs:

(setq TeX-PDF-mode t)
(setq TeX-source-correlate-mode t)
(setq TeX-source-correlate-method 'synctex)
(setq TeX-view-program-list
'(("Sumatra PDF" ("\"C:/Program Files (x86)/SumatraPDF/SumatraPDF.exe\" -reuse-instance"
   (mode-io-correlate " -forward-search %b %n ") " %o"))))

(eval-after-load 'tex
 '(progn
   (assq-delete-all 'output-pdf TeX-view-program-selection)
   (add-to-list 'TeX-view-program-selection '(output-pdf "Sumatra PDF")))

My "Set inverse search" command in SumatraPDF:

"C:\Program Files (x86)\GNU Emacs 24.5\bin\runemacs.exe"  +%l "%f"

Help will be greatly appreciated.

Disclaimer: I am new to Emacs — sorry if my question is trivial.

Arash's suggestion in the comment above has solved the problem for me.

[Tex/LaTex] Setting up forward search between Emacs+AUCTeX and Evince

You can tell auctex use absolute path by changing the LaTeX command. First, you need an updated version of auctex, as Richard Hansen points out. I've installed the CVS version, but I think it should be enough updating tex.el(c).

Then, go to the "Customize AUCTex" menu:

LaTeX → Customize AUCTeX → Extend this Menu

LaTeX → Customize AUCTeX → TeX Command → TeX expand list

and add a new item:

Key: %(dir)
Expander: (lambda nil default-directory)

and save for future sessions (if you wish)

Now, go to "TeX command list" (LaTeX → Customize AUCTeX → TeX Command → TeX command list) and edit the "LaTeX" item:

Command: %`%l%(mode)%' %(dir)%t

save and, you got it!

This way works fine for me, in Ubuntu 11.10, auctex from CVS (2012-01-11), evince 3.2.1, TeX Live 2011 and emacs 23.3.

[Tex/LaTex] How to configure Emacs and AUCTeX to perform Forward and Inverse Search

This procedure will set up Emacs, AUCTeX, and the Okular viewer to handle integrated forward and inverse search. (These instructions were tested on a Debian system)

Install Emacs. To install Emacs, open up the terminal and type the command:
```
sudo apt-get install emacs
```
Install AUCTeX.

Within Emacs, run M-x package install RET auctex RET.

To test for a successful installation, just open up a .tex file Emacs with and you will see new menus concerning LaTeX.
Install Okular.
```
sudo apt-get install okular
```
If not already done, open a tex file with emacs.
In the LaTeX menu, go to "Customize AUCTeX" and click on "Extend this menu".
Then go again to LaTeX, "Customize AUCTeX", go to the "Tex Command" submenu and click on the included "Tex command" item.
From within Emacs, run
```
M-x customize-group RET TeX-command RET
```
You are now in the "Tex command group" configuration buffer. Scroll down until you reach "Tex Pdf Mode". Its value is off (nil); click on the "Toggle" button to activate this mode. Click on the "State" button and select "Save for Future Sessions". AUCTeX will now compile your TeX file using pdflatex.

You should see something like this:

For the "Save for Future Sessions", the button with the green down arrow can also be selected. When this is done, your .emacs will be updated accordingly.
Still in the "Tex command group" configuration buffer, scroll all the way down and click on the special item called "Tex View". In the "Tex view group" buffer, you have two things to do:
- activate the correlate mode between the PDF and the TeX file, and
- declare a PDF viewer which can read these correlations.
To activate the correlate mode:
1. item "Tex Source Correlate Method", click on the "Value Menu" button and select "synctex" and save for future sessions,
2. item "Tex Source Correlate Start Server", select "Always" and save,
3. item "Tex Source Correlate Mode", toggle it on and save.
To set Okular as the default PDF viewer:
1. (NOTE: this is necessary only if you are using AUCTeX 11.87 or lower, in which case you really should upgrade the package to a more recent version) item Tex View Program List then click INS
  - name: Okular
  - choice: Command
  - command: okular --unique %o#src:%n%b
2. item Tex View Program Selection then click INS
  - choice: Single predicate
  - single predicate: output-pdf
  - viewer: Okular
    
    If you just added Okular to the Tex View Program List, this choice might not appear. Restart Emacs or Set for Current Session to have it show up.
Set and save both for future sessions.
To configure Okular: in the Okular window, go to the "Settings" menu, item "Configure Okular", "Editor", select Emacs client.
To use Forward search from Emacs to Okular, just hit C-c C-v or click on the glasses button of the tool-bar to call the viewer. Okular will center its display on the intended line of the pdf.
To use Inverse search from Okular to Emacs, make sure that the Browse Tool (in the Tools menu of Okular) is enabled; then just hit Shift+Left mouse click on the pdf. Emacs will come up and position the cursor at the intended line of the TeX source.

As a sidenote, AUCTeX can also jump-to errors generated in the log file with a C-c `. If this keystroke throws an error, see Uninformative error message when using AUCTeX for an Emacs-based (i.e. cross-platform, works with the major distributions) solution.
