thebb / company-reftex Goto Github PK

Hi,
This package seems awesome and I'd love to see it working but am having difficulty.

It seems the package is installed properly, but the appropriate functions are not called when \ref{ or \eqref{ are typed.

If I type M-x c-r-l at \ref{ I do see an autocomplete menu.

Any idea why the autocomplete is not 'auto' in my case?

To try and isolate the issue, I made a virtual machine instance and installed stock Debian 10.8 and got their default emacs (version is 26.1)
Here is my .emacs

(require 'package)
(require 'reftex)

(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")
(add-to-list 'package-archives
	     '("melpa-stable" . "https://melpa.org/packages/") t)
(package-initialize)

(add-hook 'Latex-mode-hook 'turn-on-reftex)
(add-hook 'latex-mode-hook 'turn-on-reftex)

(custom-set-variables
 '(package-selected-packages (quote (company-reftex company))))
(custom-set-faces)

(use-package company
  :ensure t
  :custom
  (company-idle-delay 0.0)
  :config (global-company-mode 1))

(eval-after-load "company"
  '(add-to-list
    'company-backends
    'company-reftex-labels
    'company-reftex-citations))

If someone could provide some tips or a minimal example of a working .emacs that would be very helpful. Thank you!

Hi @TheBB,

Quick question pertaining to a feature request. As of now, when I use company-reftex to search for label candidates, I notice that the selection of labels does not get updated after starting my emacs session. To overcome this I normally have to execute reftex-parse-all to manually refresh the selection of labels. Do you or others also experience this issue or is there some easy workaround?

I found this to be the relevant section of code:

I noticed that the following edit on line 229 fixes the issue for me, and would be happy to submit a PR. WDYT?

;; Labels 
  
 (defun company-reftex-label-candidates (prefix) 
   "Find all label candidates matching PREFIX." 
   (reftex-access-scan-info)
   (reftex-parse-all) 
   (cl-loop for entry in (symbol-value reftex-docstruct-symbol) 
            if (and (stringp (car entry)) (string-prefix-p prefix (car entry))) 
            collect 
            (company-reftex-annotate (car entry) (cl-caddr entry)))) 

Hello, thank you for developing this awesome tool!

I have a question regarding a possible feature expansion for company-reftex-citations. As per line 183, any input prefix is escaped for text searches.

As a result, when I enter an empty string or an arbitrary placeholder such as .*, company-reftex-citations does not return any candidates. Do you reckon it would be possible to loosen the constraints, such that inputting an empty string or .* returns all possible citation candidates? The user can then narrow down the list by typing further prefixes.

I would be happy to develop this, if this feature is of interest. Thank you for your time.

On the first time it's used to complete a reference, company-reftex-citations makes Emacs open the bib file in the background without the user explicitly intending to do so.

To reproduce, open a tex file with a bibliograhy and complete a reference inside, e.g. \cite{}. In my case, C-x C-b at this point lists the bibliography file among open buffers.

Hi there!

It seems that the backend doesn't support fuzzy matching: I want to be able to match the following citation with key smith2020anexamplecitation by typing sm20 for example.

I don't understand elisp very well, but from reading the code, it seems that this is not supported. Would it be possible to add it?

Just a minor request: Can company-reftex-labels use a customizable regexp for its prefix command instead of the hardcoded string? This way it would be possible to support LaTeX packages like cleveref with their additional ref commands (like \cref and \Cref).

It would be nice to make company-reftex-annotate-labels a string, which is then passed to reftex-format-citation to format the annotation (see also company-reftex-citations-regexp). The default would be "%t".

Also, I think it would be no harm to let company-reftex-citations-regexp match anything of the form \\[[:alpha:]]*cite, so it catches \textcite, \parencite, etc.
