[Pharo-project] Drag and Drop - drag from hook

by Sean P. DeNigris

Is there a hook sent to the containing morph when one of its submorphs gets dragged out? I don't see one. Thanks. Sean -- View this message in context: http://forum.world.st/Drag-and-Drop-drag-from-hook-tp4282507p4282507.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

It's important to think about the wider world, but the tiobe index is rubbish. It's based on search engine hits for goodness sake. Of what is "talking about a language", especially in the uber-democratic-everyone's-a-technical-blogger web a good indicator? -- View this message in context: http://forum.world.st/Re-Most-wanted-programming-language-tp4280758p4282434… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] SmallLint

by Lukas Renggli

Hi Simon, > The correction of some rules can be automated (eg Rule Unnecessary "= true" or Variable not reference) -> add transformation to these rules. Yes, that would be nice. > Some rules such as Spelling rules (eg comments Method: Checks for spelling errors in method comments., 7088 problems) are not very interesting and could be removed (or treated differently?) I like them, but if you don't want the spelling rules you don't have to load or run them. One thing to improve here would be the spell checker: Critics only uses a decent spell checker on OS X, where the one from the platform is available through a primitive. On all other platforms a very stupid spell checker based on a word-list is used. > Adding an indice of difficulty to correct the rule: > - Level of automation for the correction of the rule (automatic, semi-automatic, â¦). Actually this information is there: rules correct automatically if the rule is a subclass of RBTransformationRule. > - Scope of the rule (block, method, class â¦). Not sure what you mean, but you can scope the rules to any RBEnvironment (see http://www.lukas-renggli.ch/blog/programmatically-run-lint) > Other costs could be > - cost of applying (may be the rule requires to compute something else, or if a rule has 50000 hits, it generates an extra cost to analyze the results) > - cost of NOT applying the rule (if it could detect a bug and we don' t apply it ...) There is something like this in RBLintRule>>#severity. The severity is shown as an icon in OB. > Adding a manifest to manage/mark falses positive: > - one manifest (a class) by package. > - Manifest: exclusion of class/method of the package for rules or for all the rules. > - Exclusion of rules for the package. See http://www.lukas-renggli.ch/blog/ignoring-lint-rules. Also many years ago I wrote some infrastructure to run critics rules as part of the tests, what essentially served as a runnable manifest. The code is in http://source.lukas-renggli.ch/essential.html, but it likely needs some fixes to make it work in a recent version of Pharo. > One could also think on how to efficiently visualize the results of smallLint ... See for example the SmallLint results of Seaside 3.0 run by Jenkins: http://jenkins.lukas-renggli.ch/job/Seaside%203.0/791/checkstyleResult/. Cheers, Lukas -- Lukas Renggli www.lukas-renggli.ch

Re: [Pharo-project] Cog+linux: external module not found

by Schwab,Wilhelm K

Sig, I *did* miss your proposal to move the logic, but it certainly makes sense and would (I have to think) be easier to debug and change than the current situation. >From my (mis)adventures more than a year ago, I learned that plugins are libraries, but libraries are not necessarily plugins. It is not an important distinction (mostly cosmetic), but the vm code *appeared* strongly biased toward plugins at the expense of arbitrary libraries. Running with your idea, I would also suggest that we at least consider moving the mapping of serial port numbers and names into the image. Any time the vm translates a path/string/name/whatever and can't find the target, it would be nice to know what it was "thinking." The more things like this are in the image, the easier it will be to provide exceptions with informative content - less guesswork, more problem-solving. I like it. Give my regards to Spock.

I spent significant time researching this behavior, and have tried to share what I believe it all says we should be doing. > maybe you did missed it, i suggested to move all library/module/plugin search logic into image side while leave only direct calls to dlopen() (or analoguous platform-specific call) in VM. In that way, we could be able to have better control and diagnose problems of (not)finding libs and so on. Because the library lookup mechanism which is currently hardcoded in VM doesn't makes me feel happy. -- Best regards, Igor Stasenko.
