We use it for the core of our AGI and our in-memory graph db in full production - very very fast. The web libraries for lisp are very good as well with Fukamachi libraries, such as [1] caveman and [2] woo (fastest web server), [3] dexador, [4] websockets, also [5] parallel processing, [6] rtg-math incredibly fast math library including quaternion support, etc. [1] https://github.com/fukamachi/caveman [2] https://github.com/fukamachi/woo [3] https://github.com/fukamachi/dexador [4] https://github.com/fukamachi/websocket-driver [5] https://github.com/lmj/lparallel [6] https://github.com/cbaggers/rtg-math

"As Caveman bases on Clack/Lack, you can choose which server to run on -- Hunchentoot, mod_lisp or FastCGI" https://github.com/fukamachi/caveman/blob/master/README.mark... Take a look at Clack. (Caveman2 is a web framework for Common Lisp, by Eitaro ("8arrow") Fukamachi; another recent web framework is Lucerne, by Fernando Borretti ("eudoxia0")) Caveman is built on top of Clack and I think Lucerne is, too. Another good option is Ningle, by Eitaro, which is a really mínimal minimal set of functions and macros to create a web application. Runs on top of Clack as well.

"The most popular web server for CL, Hunchentoot hasn't been touched (based on the darcs repo anyway) since Tue, 24 Aug 2010." That statement is just untrue, take a look yourself. https://github.com/edicl/hunchentoot/commits/master Also there is an active community in Japan from what I can gather from github.com They done cl-annot[1], which is a way to annotate functions with the @ syntax from python. Clack[2], the WSGI-equivalent for cl. And the Caveman[3] and Ningle[4] webframeworks.

The announcement speaks as if web applications in Common Lisp was itself a solved problem. The community surrounding that isn't exactly vibrant. An example from an attempt to find a viable/nice Common Lisp templating library for making web apps (a problem for me before, I hate CL-WHO. Vile.) http://www.cl-user.net/asp/U5Hd/sdataQGW2OvQLz758DQdX8yMX8yB... Hrm. Yes. Hrm. Seems promising, exceeeept... https://groups.google.com/group/cl-terrace/web/djula The Google Group for it has...disappeared? http://common-lisp.net/project/bpm/darcs/djula/ Yay, code! That hasn't been touched since 2008! CL-WHO, which I think is the most popular way to solve this problem hasn't been touched in 2 to 7 months, depending on how you measure it. See here: https://github.com/edicl/cl-who The Ningle web framework for Clack, found here: https://github.com/fukamach
Read the rest
i/ningle Not been touched in 4-8 months. Caveman (clack framework): https://github.com/fukamachi/caveman/ 4-8 months. HTML-TEMPLATE hasn't been touched since Tue, 02 Dec 2008. The most popular web server for CL, Hunchentoot hasn't been touched (based on the darcs repo anyway) since Tue, 24 Aug 2010. Take a look for yourself: http://common-lisp.net/~loliveira/ediware/ The Common Lisp community is moribund at best. I would PREFER to use Common Lisp over, say, Clojure or Python however the fact is that there just aren't enough people using it or maintaining web development software for it to overcome the time expenditure trade-offs. So, can we drop the triumphant tone as it concerns CL? Even Paul Graham tells most people to just use Clojure.
