how can I find out the emacs version?

how can I find out the emacs version?

[Tamas Papp]

Hi,

I would like to find out the version number of my emacs -- I want to
make the font choice in .emacs conditional on whether the version is
smaller than 23 (because from 23, it supports TrueType fonts with xft).

I found emacs-version, but that returns a string.  Do you I have to
parse this for the version _number_, or is there another way?

Thanks,

Tamas

There are emacs-major-version and emacs-minor-version.

You can use

	(defconst mEV (emacs-version) "optional info string")

and then

	(unless (string-match "Step 8" mEV)
	(if (not (string-match "Step 9" mEV))
	(if (string-match "22" mEV)
	(if (or (string-match "trio" mEV) (string-match "iBook" mEV)

I am fighting with Emacsen of different versions built on different  
machines, so emacs-major-version or emacs-minor-version are not  
sufficient.

Mostly it is better to test for a feature, function or variable
instead of a version number[1].  I don't know which one would be
suitable for XFT.
