Is it important for the user to have control over this? The only reason

I can think of for keeping support for one auto folder in the master

location would be backwards compatibility with old auto folders.

 

To Arash:

I think I've narrowed it down a bit, I have mingw-w64-x86_64-sed

installed. If I remove the package, it uses the /usr/bin/sed and

finishes with no issues. So the problem seems to either be with the

mingw-w64-x86_64-sed or incorrect handling of that variant of sed by the

configure script.

As far as I know, the simplest use-package definition would be to just

load a preinstalled package. The following two lines would be

equivalent if I'm not mistaken:

 

(use-package vlf)

(require 'vlf)

 

Since vlf (very large file mode) is not part of Emacs itself, I also

need to use the :ensure keyword in my .emacs file. If vlf is not found

in the load-path, this will use package.el to install it automatically:

 

(use-package vlf

  :ensure t)

 

The problem with AUCTeX is that there's no (provide 'auctex) feature, so

(use-package auctex) will fail because it can't (require 'auctex). If

I'm not mistaken, the reason there's no (provide 'auctex) is because

AUCTeX redefines already existing modes, i.e. plain-tex-mode and

latex-mode. Now, with the following lines however, use-package will make

sure the auctex package is installed and then (require 'tex):

 

(use-package tex

  :ensure auctex)

 

Now, to the question whether to use (use-package tex) vs. (use-package

latex): I think it doesn't matter precisely because the features AUCTeX

implements already exist. Having the .emacs.d/elpa/auctex-13.1.3 folder

in the load-path (which package.el will do automatically upon

installation) will make sure AUCTeX is used instead of the Emacs

TeX-mode, so neither (require 'tex) nor (require 'latex) seem to be

necessary at all.

 

I guess Emacs already loads all of the packages at some point after the

user init file? Not quite sure. If that's not it, then I guess

(use-package latex) also works because latex.el has (require 'tex) at

the top.

 

I've also remembered why I specifically wanted to work with (use-package

latex) rather than (use-package tex): I wanted to redefine keybindings

of the LaTeX-mode-map, for which I need to (require 'latex)

resp. (use-package latex) in the init file already:

 

(use-package latex

  :ensure auctex

  :bind

  (:map LaTeX-mode-map

        ("C-c b" . TeX-command-buffer)             

        ("C-c C-b" . align-current)

        ("C-c c" . TeX-command-master)             

        ("C-c C-c" . comment-or-uncomment-region))

  :init

  (add-hook 'TeX-after-compilation-finished-functions

            #'TeX-revert-document-buffer))

 

On a side note, I've also just noticed that I don't have to :ensure the

auctex package is installed in the (use-package reftex) definition since

reftex is part of Emacs. I thought it was part of AUCTeX as well.

 

So, long story short, (use-package tex) is fine as long as you don't

need to modify any of another provided package's definitions. If I'm not

mistaken though, use-package should work with any other of the provided

packages.
