• How to access html request parameters for a .rhtml page served by webrick?

  - by cibercitizen1

  I'm using webrick (the built-in ruby webserver) to serve .rhtml files (html with ruby code embedded --like jsp). It works fine, but I can't figure out how to access parameters (e.g. http://localhost/mypage.html?foo=bar) from within the ruby code in the .rhtml file.

• Is it possible to keep mysql migration running without keeping connection open?

  - by taw

  ALTER TABLE can easily take a few days - and during this time there's a non-negligible chance of connection getting terminated due to network problems. Is it possible to start ALTER TABLE (or CREATE TABLE ... SELECT ...; or some other very long running query) and leave it running without keeping connection open all the time? (the obvious solution of screen + console mysql client won't easily work as there's no ssh running on that server, only mysqld).

• How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

  - by Sim

  If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?
