Don't worry: I probably added those by accident when rebasing.

Anyway, I pushed both patches and updated the Worg page.  Let me know if
everything is OK.

So if something should be in ALL letters the advised method would be to
use LCO file or set the location variable.  I’m just concerned with having
too many variables.  ox-koma-letter is already fairly complex.

It might make sense to NOT parse (i.e. interpret org syntax) the keyword
version or location then.  Then you’d be able to add latex commands there.
The headline version would still be parsed.

I think that's alright.

Just to recap: I use the "location" field, intended as a general purpose
extension field, for bank details.  Those details shouldn't be in every
letter I write and I don't want to have to enter those details every
time they are used.  For those reasons I put the bank details in
variable in a LCO file and toggle the inclusion by setting the
:LOCATION: (or :EXPORT_LOCATION) property like this:

:EXPORT_LOCATION: \usekomavar{frombank}

As long as I can still do that I don't
mind.

That's fine, but one might want to put information there that's specific
to a particular letter (and thus no LCO file is readily available or is an
additional level of complexity).

I’m arguing for a solution that supports BOTH "one-off" and permanent
data.

The keyword is convenient when you want to insert a pointer to field.  I

But for a one-off letter where I might need to include "one-off" details
on the left, I’d rather type:

* bank details :location:
  Acc. No.: 1234567890
  at Big Bank
  Sort Code: 11-22-33

Than

#+latex_header: \setkomavar{frombank}{\raggedright 
Acc.~No.:\,1234567890\\at Big Bank\\Sort Code: 11-22-33}
#+Location: \usekomavar{frombank}

To me the former reads much easier and hides away the technical details.
Thus, I wish to see to see support for entry forms.

OK, sorry, I thought you were arguing for a heading tagged :location:

Alright, I get the general idea but in that specific case this would be
simpler:

I have a strong taste for feature parity...  I'm very busy until at least
Thursday due to travel.  Maybe I can do it next weekend.  Unless you beat
me to it.

I will try to merge your patch soon, this weekend.  Again, unless someone

Do you mean like this:

\setkomavar{location}{\usekomavar{frombank}}

I don't understand why I would want to do that because I would have to
use a different LCO file depending on whether I was writing to my bank
or not.

Following on from my not understanding, any chance of an example of how
to do that showing what variable to set when writing to my bank, (to
cause the location variable to be populated with bank details)?

Err, yes it is?  And anyway, that data is in my LCO file, I don't want
to duplicate it.

Yes, that is what I have done (hmmm, I am beginning to sense a
fundamental misunderstanding here).  My bank account details are
permanent data and are in a LCO file.

> And maybe #+include: "bank-info.org".

The way you have edited my original email in your reply makes it
difficult to follow what is being discussed.  I would like to clarify
the main point by quoting from my original message:

#+BEGIN_QUOTE
...I would still prefer this way for the simple case of
inserting bank details:

__

** Change of address
:EXPORT_LOCATION: \usekomavar{frombank}

I have moved.
__

Where the frombank variable has been set in the LCO file:

\setkomavar{frombank}{\raggedright Acc.~No.:\,1234567890\\at Big
  Bank\\Sort Code: 11-22-33}

The bank details only appear in a letter when the property is set.
#+END_QUOTE

That property mentioned is the :EXPORT_LOCATION: property.  You can set
it to whatever you like, referencing something in your LCO file or
temporary data.

It's Nicolas’ creation, not mine.  I merely contribute a few patches

OK.

You could have this is a LCO file as well.  If so, you might be able to
populate location using \ifkomavarempty{}{}.  I use this in my standard
footer to insert fields depending on which variables are set.

But is it much neater than:

** bank details :location:
Acc. no.: 12345
Big Bank Corp
Sort code: 1122 

For temporary data, I’d rather have it like in my example.  For permanent
data I can keep it in a .lco file.

And maybe #+include: "bank-info.org".

Thanks,
Rasmus

Thanks, those are all useful fields I didn't know about.  The
description of "frombank" indicates that "location" is still a good
place for bank account details.

Given that "location" is intended as a "user's extension field" I
suppose that a special tagged :location: heading would be convenient for
some uses, if you want to add it.  For most cases however, I think its
use would break up the structure of the org-mode letter so I would still
prefer this way for the simple case of inserting bank details:

__

** Change of address
:EXPORT_LOCATION: \usekomavar{frombank}

I have moved.
__

Where the frombank variable has been set in the LCO file:

\setkomavar{frombank}{\raggedright Acc.~No.:\,1234567890\\at Big
  Bank\\Sort Code: 11-22-33}

The bank details only appear in a letter when the property is set.

Which is much neater than the special heading approach, something like
this:

__

** Change of address

*** Location field:location:
\usekomavar{frombank}

*** Rest of letter
I have moved.
__

Hi Myles,

Thanks for your patch.

It always makes me happy when someone is using ox-koma-letter.

Aside: it sounds like what you need is "yourref", maybe "yourmail",
"myref", "customer", and "invoice".  These are typed in the same line as
the date and place.  In my manual it’s described around pp. 180.

On to "location".  From the manual pp. 195 it looks like it is usually
something akin to an address field on the right side of the head.  I think
"location" should be settable via a special :location: heading, probably
with special line breaking rules like the :to:/:from: special headings.
We can allow a #+LOCATION keyword in addition, but need not.  All IMO.
WDYT?

Thanks,
Rasmus

[O] [PATCH] ox-koma-letter.el: Add support for 'location' koma variable

[Myles English]

Hello,

Often when writing a letter I want to include "Your Ref: xyz" or
"Account No.: 1234" and a good place to do this is below the sender's
address field and above the date (and 'place') field(s).  This space
becomes filled with the contents of the koma variable called 'location'.
This patch enables filling this variable via org-mode's contrib
ox-koma-letter exporter.

Please apply the attached patch.

Myles

Subject: [PATCH] ox-koma-letter: Add support for LOCATION koma variable

* contrib/lisp/ox-koma-letter.el (koma-letter): Duplicated code
  used for 'place' variable, renamed as 'location'

Whenever OPTION keyword contains a 'location' item or LOCATION
keyword is used in the buffer, set KOMA option 'location' after
LCO inclusion.
