Pharo program "examples"

by Hans Schueren

Thanks Jan , i know that the system itself is the program. But there must be "Image" programs out there to download. I only want to download a program ( Folder with image and exe [Pharo Container] ) Online. Just to see and start the program and see how it opens. ( like a normal program [ Pharo IDE is shadowed] ). Guess that i am a user. I have heared about Pharo and want to test a real program. Hans Hello again , are there any Pharo Program examples online ? I dont mean normal examples from coding. What i mean are end-user programs. Completely ready Online for downloading. Regards Hans

Trying to calculate it after method replaceWith:. You see, my proble was that each node of AST doesn't hold its start and stop position in same place. So I thought that token is such a place, however, eventually I understood that RBValueNodes don't have tokens:) > Example of how it is done: > > RBPragmaNode > accessing-tokens gives access to left and right, which are > positions, not tokens. > Yes, I know. > > Thierry > > >> Mark >> >> >> >> 2014-10-28 11:59 GMT+02:00 Nicolai Hess <nicolaihess(a)web.de >> <mailto:nicolaihess@web.de>>: >> >> 2014-10-27 19:36 GMT+01:00 Mark Rizun <mrizun(a)gmail.com >> <mailto:mrizun@gmail.com>>: >> >> Hi all, >> >> Trying to understand here how tokens are used in AST. >> So far I can not see any order in usage of tokens. >> For instance, why RBValueNode doesn't have token?

Well, not really. Technically, tokens are used to drive a parser from a scanner. If an AST node knows how to relate itself to its original source code chunk and is able to print itself correctly, then tokens are redundant. In short, if you work with parsers, you'd better know what tokens are. If you're only working with the AST, tokens are redundant and noise (i.e. they often have a type (or more than one) which is only understood by the parser). Example of how it is done: RBPragmaNode accessing-tokens gives access to left and right, which are positions, not tokens.

Tokens expose a very low level implementation artefact of the parser to the AST model, this is not good. There isâ¦ https://pharo.fogbugz.com/f/cases/11992/Remove-tokens-from-the-AST-Core-Nod… We should have a look at that and integrate it. This should simplify lots of things. Marcus

Thanks. I see that, however RBBlockNode or RBArrayNode doesn't have tokens. These classes have only methods in accessing-token protocol. I think it would be better if we have token object for those classes, because it makes more sense to hold such information in token object.

Mouse wheel scrolling not working right on Windows

by Jan B.

Hello I am reposting this from Moose mailing list, because it seems like problem in Pharo itself. In HandMorph>>#generateKeyboardEvent: is a condition based on charCode which tells whether incoming input event is of keyboard type or mousewheel type (code quoted below). On Linux, when I use mouse wheel, keyValue and charCode are both 30 or 31 respectively. But on Windows there is keyValue 30 or 31, but charCode 0. This condition is based on charCode being 30 or 31 so it absolutely never returns MouseWheelEvent. When I replace charCode with keyValue there, mouse wheel works fine (but I am not sure whether it might not break something else). Pharo core windows like System browser or Monticello seem to somehow get around it and work, but nothing else, like Roassal where I reported this bug before, so in whole Roassal mouse wheel does not work on Windows.
