Hi all,

I have a simple question, but I wasn't able to find answer on the web,
so finally I'll try my luck here.

I know I can setq org-todo-keywords with a list '((sequence "TODO"
DONE")), as an example. But what variable is used for per-file keywords?
Once that are set with #+TODO: ... line?

I guess when org mode parses a file when starting up the mode, it has to
parse that line into some var, where do I find it?

Thanks in advance!

Best regards
/a

Use a file local variable?

That said (or rather, asked), I don't know whether there is a specific
Org way to achieve that.

As I understand the manual, the org specific way is to use per file
variable, but instead of using Emacs _*_ for file variables, org uses #+
and they do their own parsing seems like. I might missunderstand, but
the syntax to use is: 

#+TODO: keyword1 keyword2 ... keywordN

I was looking around in org.el a bit now, and I see there are three vars
associated with per-file todo keywords: org-todo-keywords-1
org-todo-kwd-alist and org-todo-key-alist which seem to be set in
org-set-regexps-and-options function. I'll see if I can refactore
something out from there for my purpose.

Thanks Rusell; but I have seen the manual as I wrote. I am aware I can
use

#+TODO:

syntax to set per file keywords. I wanted to do this from lisp, since I
can't use labels with multiple words with that syntax since spaces are
used as delimiters for keywords, but I can pass strings (with spaces)
with lisp.

as you discovered, spaces can work for todo kw for at least some
purposes.  [i have one, because i prefer space to snake_case and
kebab-case might not search well.]  but you should check to see if it
is guaranteed to work.  i vaguely recall spc is not allowable.

if it were guaranteed to work, then there would likely be a mechanism
to include it in the #+ syntax.  :)

Indeed, I am aware that spaces are not so welcome in some places
:). However this works fine:

(setq org-todo-keywords '((sequence "first label" "second label")))

If it is guaranteed or not I have no idea, maybe some other APIs in org
are expecting labels to be single words, but for simple purpose it seems
to work. #+ could actually use just "" as grouping items or {}. For
example: 

#+TODO: "item one" "item two" ... "item n"

or with {}

#+TODO: {item one} {item two} ... {item n}

When I tried, I got citation characters included in my label, which
wasn't really what I wanted either :).

It is parsed into a buffer-local variable by the name of
`org-todo-keywords-1'. Do `C-h v org-todo-keywords' and `C-h v
org-todo-keywords-1' for all the details.

BTW, when the interwebs fail you (or even before that), use the source :-)

Yes indeed! I used the source Luke! :)

I found that one, unfortunately it is not enough to set that one to my
keywords. There are also two lists in play org-todo-kwd-alist and
org-todo-key-alist which are set in one mastodont method, but I think I
can refactor that out. I have to figure out how to build alist comming
from out org-collect-keywords which is input to that part of
code. Didn't had time last night, will see if I have time today.

Arthur Miller <arthur.miller@live.com> writes:

If anyone is interested, this is how I understand the org TODO per file
parsing:

The file is parsed in org-collect-keywords-1 in org.el.

Each #+TODO: line is lumped into one single string, which is a problem
when strings with spaces a concerned. Multiple #+TODO: lines will end up
in final multiple strings added into an alist which has a first element
a "TODO" string. The right thing would be to parse multiple strings per
each #+TODO: line. Now the org-collect-keyword-1 is not a trivial one,
so it would take me quite some time to understand, so I'll pass.

The thing I did that worked for me is wrong super-hackish thing, just an
experiment, so to say.

I have simply refactored the code where the string obtained from
org-collect-keywords is parsed, which is the very last part of
org-set-regexps-and-options, where main action seems to take place. That
let's me do what I wanted. It will completely replace whatever was
specified with #+ syntax, and the fontification won't be done
either. Also if file is reverted than #+ will completely replace what
was set with lisp. So not a clean thing, probably nothing to be used by
anyone, but it does what I roughly need for my init file :-).
