Dickey <dickey@invisible-island.net> > http://invisible-island.net > ftp://invisible-island.net reflex seems like a better solution for us than upgrade to flex (from sourceforge) imho, flex depends on m4 and on some gnu m4 extensions, normally our version of m4 is now compatible with gnu m4 (I added some missing bits recently) but still I don't think having flex using m4 is a good idea, and reflex looks cleaner in that area. reflex is just missing imho one feature from flex (sourceforge version) that is ability to generate reentrant code. I already imported byacc from invisible island, I was supposed to add some "fixes" to byacc (bde has spotted) and provide them to Thomas, sorry I have been slacking in that area recently. Once that is done, I have on my todo list importing reflex to replace our flex. I did feel any hurry in that area, as I don't think we are missing too much features, is there one you are particulary interested on? I was waiting for reflex to support reentrant code generation before importing it. regards, Bapt [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlAYRzcACgkQ8kTtMUmk6EymOACeICfDi+PKUWFZgt07bKtaLeEj L18AoKTi/faAXjILCyHtBUp1YdFoO5/q =bOlp -----END PGP SIGNATURE-----home | help
