Wrong number of arguments: setq, 1

Wrong number of arguments: setq, 1

[Kaushal Modi]

Hi,

I needed to make these changes locally to make any kind of org export
(text, html, latex) work.

Without these fixes, I get an error like: Wrong number of arguments: setq, 1

I am not familiar with letrec but for let statements, if I want to set
a let-bound variable X's value to nil, I would do,

(let (X) ..)

or

(let ((X nil)) ..)

But NOT (let ((X)) ..) (Note the parentheses count).


Do the same rules not apply to letrec?

Here is my org-version:

Org-mode version 8.3.2 (release_8.3.2-380-g64aee4 @

Here is my emacs build info (emacs-25 branch):

I just found a recent conversation on this mailing list with the
title: Concerning `(letrec ((ignore)) ...)' in line 2718 of lisp/ox.el

That explains why I suddenly started seeing these errors.
My above patch fixes org exports for me while being on the latest
snapshot of emacs-25 branch.

I don't. Version info:

They do not: letrec takes a list, each element of which is
a list (SYMBOL VALUEFORM) - but afaik, an empty VALUEFORM
sets the SYMBOL to nil.

let takes a VARLIST, each element of which is a symbol *or* a
list (SYMBOL VALUEFORM).

See their docstrings.

My org is the same as yours, but my emacs is a few months old: maybe
some recent change screwed up something.

Your Emacs 25 build isn't recent enough to have the issue.  See
