Re: [Pharo-users] The Grapher charting engine

by Tudor Girba

Hi, I fully agree with your API suggestions, but I do not quite understand why you say that it is because of the scripting that the API does not look like this. It's the opposite I think. When you "script" you want as succinct as possible (so, no moveBehind: and stuff). And you want to gradually add details and not be forced to specify them from the very beginning (so, good defaults). In fact, the rule of thumb that I argue for is that a good scripting (and in fact any API) interface is one that allows you to make a difference with any new line of code. That means that, ideally, we would want every line to be able to live on its own and not require another one. It's obviously not always possible, but I find it helps me when I grow an API.

The Grapher charting engine

by stepharo

Alex Roassal is really cool now I have one question why we cannot say serie1pointsAndVariations :- given series2pointsAndVariations := given RGrapher new axisX; axisY; seriesWithDeviation: {serie1pointsAndVariations . serie2pointsAndVariations}; maxXAxis: 100; My point is why the line connection is not hidden from the user. I think that roassal is a cool scripting engine but it got ***trapped*** there. A primary user wants to have abstractions Then in a second time he wants to open the trunk and script its own. also why don't you have nice default dec := RTDevVarDecorator new. dec moveBehind; desviation: 0.5; color: (c alpha: 0.3); points: pts. => dec := RTDevVarDecorator new. desviation: 0.5; color: c; points: pts. why the decorator should be added to the builder? So see what I mean why do you expose to the user all the design challenges? I strongly suggest that during 1 month you stop to think in term of script. Imagine that you do not have a workspace anymore.

Re: [Pharo-users] Pharo-Launcher Windows 8.1

by kilon alios

Bottom line is that reporting a problem in the mailing list first makes much more sense because a) Way more likely to get an answer b) Avoid adding to the list on non existent bugs in fogbugz c) Bring the bug if it really exists to the attention of more people, hence increase that chance of the bug getting a fix. d) Far easier to remind people of the bug later on by just bumping on the thread which everyone on the list will get notified compared to fogbugz that if you are not subscribed to a bug you wont be notified. So yes definitely want to discourage people from starting from fogbugz. Also personally I dont like fogbugz because its so isolated.
