Re: [O] Changed behaviours of LaTeX exporter in version 8.0+

[Kyeong Soo (Joseph) Kim]

Nicolas and All,

One further question regarding your suggestion of the use of filter for special blocks in export:

I just found out that, if I close Emacs and relaunch it, all variables for filter (i.e., 'org-export-filter-*') are not defined. As a result, the following elisp codes for the workaround based on both your suggestion and the filter example in the manual causes void variable error (i.e., "Symbol's value as variable is void: org-export-filter-special-block-function"):

;; workaround solution (until 8.3.0) for case-sensitve handling of special-block for IEEE LaTeX class

(defun my-latex-filter-ieeekeywords (text backend info)

  "Upcase 'IEEE' in IEEEkeywords environment in LaTeX export."

  (when (org-export-derived-backend-p backend 'latex)

(replace-regexp-in-string "ieeekeywords" "IEEEkeywords" text)))

(add-to-list 'org-export-filter-special-block-functions

'my-latex-filter-ieeekeywords)

It turns out that those variables are defined only after exporting org file into LaTeX.

Again, any advice on propor addition of custom filter functions in the configuration file would be greatly appreciated; maybe the said example in the manual needs to be updated as well.

Regards,

Joseph

I'm surprised {{{KEYWORDS}}} even worked as, AFAIK, it wasn't
documented.  Indeed, there is no such macro in Org 8.0.  However, you
can define your own

'{{{KEYWORDS}}}' worked without any issues in previous versions, which in fact was suggested by someone in the mailing list or stackoverflow (unfortunately, I couldn't find that via Google any longer).

By the way, in Sec. 12.3 of the Org manual (ver. 8.2.7c), 'KEYWORDS' is listed together with 'AUTHOR', 'TITLE' and so on as export keywords. Also, according to Sec. 11.6, those predefined keywords (e.g.,  #+TITLE:, #+AUTHOR:) can be accessed by {{{title}}} and {{{author}}} like user-defined macros.

It seems that there is some inconsistency between the actual behavior and the corresponding manual in export engine of org-mode ver. 8.2.7c.
