how to customize date export

how to customize date export

[Mirko Vukovic]

Hello,

I could not figure out how to customize org's export of dates into latex.

I found org-export-date-timestamp-format, but that works only for the DATE
keyword.  

What can work on all date-stamps in the document?

Thanks,

Mirko

Have a look at

,----[ C-h v org-latex-active-timestamp-format RET ]
| org-latex-active-timestamp-format is a variable defined in `ox-latex.el'.
| Its value is "\\textit{%s}"
| 
| Documentation:
| A printf format string to be applied to active timestamps.
| 
| You can customize this variable.
| 
| [back]
`----

and 

,----[ C-h v org-latex-inactive-timestamp-format RET ]
| org-latex-inactive-timestamp-format is a variable defined in `ox-latex.el'.
| Its value is "\\textit{%s}"
| 
| Documentation:
| A printf format string to be applied to inactive timestamps.
| 
| You can customize this variable.
| 
| [back]
`----

but these are quite different in intent when compared with
org-export-date-timestamp-format so they may not be what you want.

Hi Eric,

Thanks for the note.  As it stands now, I cannot
customize these two variables to do what I want, as they accept the
whole time-steamp as argument.  I will enter the dates manually
in the org file for now.

Maybe they ought to be re-cast in manner similar to which
org-export-date-timestamp-format is handled?  A nice weekend project :-)

I thought as much.  

Looking through the code, some of the functions for outputting the time
stamps make use of org-translate-time which does allow some
customisation of how the dates and times are written out, along the
lines of what you were looking at for DATE entries.  Check the
documentation for that function.  But it could be I've misunderstood the
code...

Based on Eric's hint, I followed org-translate-time's docstring (and
references therein) and I came up with this which seems to work (in the
sense that the dates look like <2014/02/03 Monday> when exported,
which agrees with the specified format):

--8<---------------cut here---------------start------------->8---
#+STARTUP: customtime

* foo
<2014-02-03 Mon>

# Local Variables:
# org-time-stamp-custom-formats: ("<%Y/%m/%d %A>" . "<%Y/%m/%d %A %H:%M>")
# End:
--8<---------------cut here---------------end--------------->8---

However, the angle brackets seem to be required.

I'm glad my hint was helpful.  Interestingly, the angle brackets are not
required per se.  However, there does have to be some character there,
in both places, and that character is replaced by an angle bracket on
export (and probably on display as well but I am using BIND instead of
local variable settings to set the custom format).

You could use a filter to get rid of the angle brackets for instance
org-export-filter-timestamp-functions.  There's also parse-time-string
together with the relevant DATE-formatting variables that can be used
to recast the appearance of time.
