org-bibtex manual

Hi

I have been reading about org-bibtex, and I think the mail list were 
right when advised it to me 
(https://lists.gnu.org/archive/html/emacs-orgmode/2021-10/msg00621.html).

Now... I would like to start using it. I have seen it has a kind of 
org-capture template (M-x org-bibtex-create-in-current-entry).

If I wanted to add more properties:

- How should the different properties be named and filled to work correctly?

- Should the names of the properties be exactly like in Bibtex?

- Are there any existing org-capture templates with the properties each 
entry type could have? Or could you advise a manual of bibtex to create 
myself some complete templates?


Thanks!

In general, the types of properties are dictated by `org-bibtex-types',
which is declaring Bibtex standards. With C-u argument, you will be
asked for optional properties.

If you want to add non-standard properties, org-set-property will work.

Yes. Either exact, or prefixed with `org-bibtex-prefix'. Mixing
with/without prefix will also work.

See also `org-bibtex-export-arbitrary-fields'.

You can create a template by adding `org-bibtex-create'
to :hook property of your capture template:

(setq org-capture-templates '(("a" "test" entry (file "/tmp/1.org") "" :hook org-bibtex-create)))

Thanks, Ihor.

I would like to customize the name of the heading. I think it should be 
customized this function: "Org Bibtex Headline Format Function".

Is there a guide to do this?

I can see the default is:

#[257 "\300\x01\236A\207"
       [:title]
       3 "\n\n(fn ENTRY)"]


But I don't know how to customize it.

ChatGPT says:

"Unless you are an advanced Emacs Lisp developer and have a specific 
need to work with byte-compiled code, you generally don't need to 
interact with or modify this representation directly. Instead, you can 
work with the function using its regular name and definition."


And ChatGPT offers me this alternative, which doesn't seem to work (BTW, 
I am not able to install asoc.el):

#+begin_src emacs-lisp
(defun my-org-bibtex-headline-format (entry)
   "Custom function to generate the headline text for org-bibtex-write."
   (let* ((title (cdr (assoc :title entry)))
          (author (cdr (assoc :author entry))))
     (concat "Mi encabezado personalizado: " title " - " author)))

(setq org-bibtex-headline-format #'my-org-bibtex-headline-format)
#+end_src


Best regards

That's a bit misleading because of compilation.
The original code is

(defcustom org-bibtex-headline-format-function
  (lambda (entry) (cdr (assq :title entry)))
  "Function returning the headline text for `org-bibtex-write'.
It should take a single argument, the bibtex entry (an alist as
returned by `org-bibtex-read').  The default value simply returns
the entry title."
  :group 'org-bibtex
  :version "26.1"
  :package-version '(Org . "9.1")
  :type 'function)

I should factor out that lambda into a separate readable function name,
like `org-bibtex-headline-from-title'.

You do not need asoc.el.. `assoc' is the built-in function.

This is correct, but this customization only works in
`org-bibtex-write', which works together with `org-bibtex-read-buffer' /
`org-bibtex-read-file'.

`org-bibtex-create' hard-codes heading to be the same with BiBTeX :title
field.

Yes, org-bibtex is not very polished.

Hi Ihor.

Then, is it not possible to customize the entry generated with 
org-bibtex-create?

You mean fields?
Everything is defined in `org-bibtex-types', but it is not currently a defcustom.

I see no problem adding user types.

No, I mean customizing the generated headline. Instead of just title, to 
be like:

* Author (year) /Title/. Publisher
