Re: [NTG-pdftex] \pdfretval vs. expandable \pdfstrcmp

the reason is the same like in case of \pdfescapestr: I don't know tex the program well enough to make them expandable, so just made a quick hack to get it work. Anyone willing to improve them is welcome very much. Regards, Thanh On Wed, Jun 15, 2005 at 08:41:48PM +0200, Heiko Oberdiek wrote:

Hello,

is there a reason why \pdfstrcmp is not expandable? An expandable variant could be used in expandable contexts: \ifcase\numexpr\pdfstrcmp{StringA}{StringB}+1\relax ...\or ...\or ...\fi Inserting into a sorted linear list could be done in O(n): \edef\mylist{\addtolist\mylist{foo}}% Now it is O(n^2) :-(
