Howdy folks!<br>
<br>
In working on Tirade I stumbled upon SqNumberParser and its history:<br>
<br>
<a href="http://bugs.squeak.org/view.php?id=3512" target="_blank">http://bugs.squeak.org/view.php?id=3512</a><br>
<br>
...it was added to the image in 3.9 but not hooked into Scanner - Scanned still uses Number class>>readFrom:.<br>
<br>
Now... In Tirade I can use whichever - but using SqNumberParser makes it more correct, and quite faster - although "less portable" since I would depend on it. I will now make Tirade use SqNumberParser *if present* in the image, otherwise fall back on Number class>>readFrom:. This opens up some slight potential incompatibility issues, but whatever.<br>
<br>
Question: Is there anything stopping 3.9+ including Pharo to start using SqNumberParser from Scanner>>xDigit?<br>
<br>
And oh, the class name is not so good IMHO, why the Sq prefix?<br>

but then Francisco Garau prepended a Sq (to emphasize Squeak peculiarities?) and the name remained as is...<br>I am also equipped with a FORTRAN, a Dolphin and a VW Number parser, and guess what ? Smalltalk syntax vary...<br>
...But I agree, Squeak Academy should discuss new names entering in the Smalltalk dictionary ;)<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

And yeah, class var not used in SqNumberParser: BelllerophonBase10 :)</blockquote><div><br>Yes remove it, it was used once in early days, before I correct conversions Integer>>asFloat Fraction>>asFloat<br>(all started from here <a href="http://lists.squeakfoundation.org/pipermail/squeak-dev/2006-April/102465.html">http://lists.squeakfoundation.org/pipermail/squeak-dev/2006-April/102465.html</a>)<br>
