Parse specified number of elements with OMeta
by Yoshiki Ohshima 06 Dec '12

06 Dec '12

There may have been many similar attempts, but come to think of it, adding a simple higher-order rule to OMeta that applies the given rule for a given number of times is just straightforward. For example, if you want to only parse a string that represents fully padded hexadecimal digits for a 8 or 4 byte quantity, you can write: hex16or8 = numberOf(#hex. 16) | numberOf(#hex. 8) where #hex is something like: hex :c = ?[(c between $0 and: $9) or: [c between: $A and: $F] The numberOf rule looks like: numberOf :rule :count = [0]:c [OrderedCollection new]:xs ([c+1]:c ?[c <= count] apply(rule):x [xs add: x])* ?[c = (count + 1)] -> [xs] -- -- Yoshiki

Proposed 4.4 Changelog
by Frank Shearar 06 Dec '12

06 Dec '12

* Old TextMorphEditor removed, ParagraphEditor now unloadable. New stub TextMorphEditor added for legacy support (particularly Connectors) which wraps TextEditor. * Add host window support, letting you display things in a host window. (Currently only on Windows and Mac.) * Bugfixes in the Compiler, Parser and Debugger toolchain * Stub support for the ability to evolve the bytecode set * Better printing of Floats, hashing of DateAndTimes * ChangeSorter improvements * ToolBuilder improvements * Merged network improvements from Etoys * Monticello browsing can now group versions by branch, making tracking of parallel developments easier * Decreased coupling between core packages * IPv6 support (if your VM provides it) I've put the first item slightly separate because I'm not sure I summarised things accurately. If you have suggestions for improvement - particularly if there's something important I've missed - please let me know ASAP. I'd like to have all our ducks in a row by the end of the week. frank

Preferences 4.5 (was: The Inbox: ReleaseBuilder-fbs.78.mcz)
by Chris Muller 05 Dec '12

05 Dec '12

When you say you want to "get rid of Preferences" I hope you mean just the *implementation* -- e.g., the idea having a global Preferences class with a lot of stuff in it. I hope you agree we need the _functionality_ of preferences. I agree about Preferences class from a code prettiness / global=bad-design perspective, but one thing I would not want to lose is the global preferences UI. Today, I can get to any preference in under 2 seconds with three quick gestures: 1 - zip the mouse outside of active window. Desktop command keys are now active. 2 - Command+Shift+P. Preferences window opens. 3 - type a few search characters Also, there are some preferences which are truly global I don't know where you want to put them (like, uh... Desktop Cmd Keys, for example!). We could end up scattering a bunch of truly global preference variables out into various other classes. Is that a lot better?
