A single parser is a nice goal, but performance is top priority for Shout, because it should do it's job real-time. When it starts lagging behind, then people just turn it off, because it doesn't help them. Can those parsers (SHRBTextStyler and a Smalltalk parser written using PetitParser) parse an average method in less than 20ms on an average machine?

Parsing float difference between 2.0 and 3.0, was it on purpose?

by Mariano Martinez Peck

Hi guys, In Pharo 2.0, the expression "Number readFrom: '2.5850009999999998e+04' " would answer 25850.01 , but in Pharo 3.0 it answers: 2.5850009999999997 which is a kind of WTF to me. Checking the differences it seems in Pharo 2.0 ExtendedNumberParser (used from Number >> readFrom: ) implemented: allowPlusSign ^true However, in Pharo 3.0 it seems subclasses of NumberParser have been merged directly in NumberParser class (and so Number >> readFrom: uses this class now). But.. (and this is the difference), NumberParser implements: allowPlusSign ^false So I wonder...was this on purpose or a side effect? Why would we want to reject using + as part of the exponential notion?? So in my case now I must do an override to: NumberParser >> allowPlusSignInExponent ^ true Thoughts? -- Mariano http://marianopeck.wordpress.com
