Dear Smalltalkers (Pharonistas?), while trying out teapot in Pharo4, I encountered the following: I have made a plain HTML form which sends data to a teapot URL. Here is what the browser is sending: http://localhost:1701/bac/?a=88&r=0.7&kg=77 To answer this request via teapot, I wrote the following: ... GET:'\/bac\/\?a=(\d*)&r=(\d*.\d*)&kg=(\d*)' asRegex -> [:req | BloodAlcoholCalculator a:(req at:1) r:(req at:2) kg:(req at:3) ]; ... But the answer in the Browser looks like: Not Found /bac/?r=0.7&a=88&kg=77 I tested the regular expression via 'matchesRegex' and it returned 'true'. The funny thing is, that teapot changes the order of the values in the answer (r and a are switched). If I leave out the '\?' and use the resulting URL manually, teapot delivers the expected behaviour. What could be the reason for this issue and where should I search to understand it (System Browser)? Thanks for the attention and kind regards Marcus -- View this message in context: http://forum.world.st/Teapot-and-Regex-tp4840892.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
