[Pharo-project] Wrong number with message tally?

by Alexandre Bergel

Hi! MessageTally seems to give wrong values regarding the relative time spent. Consider: MessageTally spyOn: [ 100 timesRepeat: [ 1000 factorial ] ] It gives something like: -=-=-=-=-=-=-=-=-=-=-=-= - 377 tallies, 379 msec. **Tree** -------------------------------- Process: (40s) 464519168: nil -------------------------------- 65.8% {249ms} SmallInteger(Integer)>>factorial 65.8% {249ms} SmallInteger(Integer)>>factorial 65.8% {249ms} SmallInteger(Integer)>>factorial 65.8% {249ms} SmallInteger(Integer)>>factorial ... -=-=-=-=-=-=-=-=-=-=-=-= I would expect to have 100% at the root of the call graph since other threads are not reported. Is there something I am missing? If no, then I will dive into MessageTally. This is annoying.

Just for a simple inspector I end up with my image full of stuff which I don't usually want (if I do want, then I would explicitly load the rest). - it doesn't fail when there are problems with their dependencies (as it happens with Moose when having lots of dependencies) - you do not install the same software that much. I do. I build new images all the time. All in all, what I want to say is that if there are users (like me) which would like to load GTInspector only load the needed dependencies, then it would be good if you can provide them.

[Pharo-project] TextLint usage for German text?

by Franz Josef Konrad

Has somebody used TextLint to analyze German Text? I haven't found any hint in this direction. If there is no adaption for German available, do you think it can be done easily? I had a short look to the source code and saw that one of the key points of TextLint is to recognize the type of a word (noun, verb, etc.). This is done by building a dictionary of words that comes from the English Wiktionary. From a first and naive view I would guess this can be done also for German and the rules could be adopt to German styling rules. Any remark to this topic is appreciated. Btw, I would like to use TextLint for analysing text of user manuals. Regards, Franz Josef

I just want to download GTInspector and only its REAL dependencies, that is, the dependencies I need to make it work. Even if the loading would be fast, I DON'T WANT dependencies that are not dependencies. At least in this scenario. Some may want them, some may not.

I just want to download GTInspector and only its REAL dependencies, that is, the dependencies I need to make it work. Even if the loading would be fast, I DON'T WANT dependencies that are not dependencies. At least in this scenario. Some may want them, some may not. So, having a way to load GTInspector and only its real dependencies is something I would appreciate.

While things is done in a way, that you don't need to have it in order to load a project from your configuration. i.e. one can load ConfigurationOfXYZ into image without metacello and then run it, without caring if Metacello is installed or not (because configuration takes care of it).

I understand wanting a lean core image, but once a single ConfigurationOfXXX is loaded, Metacello ends up installed. So the independence is only important for the very first loaded ConfigurationOfXXX. If you are using an lean-image that does not have any ConfigurationOfXXX loaded, then you are likely an advanced user who knows how to resolve the Metacello dependency. A pre-requisite of example b> above is Gofer. I notice that PharoCore-1.3-13315.zip there is no Gopher and in Pharo-1.3-13315 there is but also ConfigurationOfGofer. Since example b> ends up with Metacello fully installed, is there any common use case where ConfigurationOfGofer would not be installed first? At which point, can we assume that Metacello is installed for example b> ? Now I assume my following proposal is flawed with respect either good practice and/or the Pharo design goals - but since (from my perspective) Metacello is a critical part of Pharo, I am interested for my learning why it would be evil to include just the following stub in PharoCore... ---8<---snip Metacello class >> doesNotUnderstand: aSymbol self ensureMetacello Metacello class >> ensureMetacello [as per the Metacello template] ---8<---snip

For example, to load just the basic Glamour, you can load it like: > (ConfigurationOfGlamour project version: 'default') load: {'Core'. 'Morphic'} The problem of dependencies is not their presence, but the time taken to load them. Removing EyeSee, Mondrian and Magritte from Glamour will not make Glamour better. However, having a smart cache mechanism on top of Metacello will definitely make all us happy. Having one single .mcz file to load instead for the whole version would be great. This should not be done by removing dependencies.

It is done at the hardware level. Since C does not specify many things including signed overflows, I would assume they just map directly onto what the hardware provides. And for all practical purposes, two's complement is the standard.
