The issue tracker has lots of interesting completion related issues, like https://pharo.fogbugz.com/f/cases/13124/NECContext-needs-plugin-design Stephan

Re: [Pharo-users] Pharo family

I move the map into github in textual file for completing it before drawing it: https://github.com/AdamSadovsky/pharo-family - Zinc is now inside - More circles can be added. I generalized it under "position", so You can change it into something else then "inside image". I dont even know what bootstrap is (it has to do something with the loading probably, but why it is important to know from this point of view). Adam. Dne Ne 4.

Re: [Pharo-users] Pharo family

by Adam

as You suggested I prepared list of projects in github. I was not able to add it into pharo-project, so I created it under my account. https://github.com/AdamSadovsky/pharo-family Still it is very incomplete version. More projects can be included, more details can be added. And moreover hierarchy of concepts could be more like this: Data/modelling Data/persistency Data/persistency/database Data/conversion Adam.

Better Code Completion

by Peter UhnÃ¡k

This is both rant and list of questions/notes/observations... ...but first of all: do Smalltalkers not like code completion? Because the one in Pharo is really poor and not only that nobody is doing anything about it, *but also nobody is complaining*; this leads me to believe that you either a) don't have the manpower (this is true pretty much always, so no complaints here) b) don't care about this that much (since you lived without it for 45 years) at least from the lack of complaining to me it seems that b) is more likely scenario... But since I do use it, I get annoyed by it quite a bit, especially since I regularly work in IDEs where this thousand times better. Now I would like to get things moving a bit (or bury it and forget it), so I have couple of questions and would appreciate if someone could provide some feedback. 1. Methods of core/top classes should be deprioritized Since Object has almost 500 methods whatever I will start typing Object/TClass/TBehavior/... will have a list of answers... so let's start typing... Very often I have to type almost full word to see what I want. Shouldn't the completion follow the inheritance chain? So first it shows me matches from the class itself (especially since it actually knows the type) and only after then it's parents and so on? 3. Or maybe even show the (closest) class that implements it. So the last two items would have somewhere (beginning or the end) written '(Object)' and the first two '(yourself)' (or the class's name). 2. The window has fixed size, so if I have longer method (as in picture above) I don't see it all. 3. Is middle-of-the word really that often used? See moseIntere<sti>ngEntity above. It feels to me that it just creates a lot of false positives (I have this problem also with inspector btw, so I often have to prefix it with >># or if I see it already lot of <arrow down>, which is annoying) 4. We write tests, however how often have you manually created an instance of a test class by hand? I think they should be either filtered or deprioritized as they create visual clutter. This is probably also true for many other classes such as ConfigurationOf/Manifest/... Nobody instantiates them by hand. 5. How often do you send #abs to a dictionary? Maybe also deprioritize extension methods? 6. If I have already written part of the selector it's impossible to "continue" and add an extra parameter. This is because it doesn't know if I am code completing for dict, or #key. Maybe different shortcuts? <tab> to code complete on #key, and <shift+tab> to code complete on the previous one... or maybe cycle through them because this can be nested (the currently code completed item would have to be highlighted somehow). 7. So if I don't want to see the above I have to type it manually; which is fine for #at:put: but not for longer words.. (just to find out ten seconds later that I have a stupid typo there). 8. The code completion doesn't show parameter names. This is very helpful because it often reveals what it actually accepts. Now I have to actually look into the code of the method. Now we can hardly compete with typed languages, but I think there's a lot lot room for improvement. For comparison from other languages/IDE's. PhpStorm/PHP (notice how it shows the whole method if it's longer than the window and doesn't it just clip)â NetBeans/C++ In the picture above it âstill provides hinting when typing the parameter. TypeScript playground â(similar to NetBeans) Also they have in their online playground better and nicer code completion than we have in actual env (http://www.typescriptlang.org/Playground ) So if you have any thoughts/feedback/whatnot on this matter, I would greatly appreciate it.

Re: [Pharo-users] Pharo family

by Volkert

+1 i like the idea of a pharo capability map with all the related projects and framework. i have the same feeling as you. For a newcomer its is really hard get a picture of what is behind the plenty strange framework names. A structured list of the main frameworks with a short description would be helpfull. Why not starting with a overview of the ecosystem & projects and put it on github (https://github.com/pharo-project) I will support you.

Interesting idea. Some feedback: * "Zinc" should probably be inside the circle * "SUnit" seems to have greater emphasis, such that for a moment it seemed that this was the label for everything in the circle. * Later it might be interesting to have several circles, showing what is in bootstrap and the normal Image. cheers -ben On Sun, Oct 4, 2015 at 7:54 AM, <adam(a)234.cz> wrote: > Hello, > > I just did a quick scatch of some projects, frameworks and concepts related to > Pharo.

Pharo family

by adam＠234.cz

Hello, I just did a quick scatch of some projects, frameworks and concepts related to Pharo. I did it because I em confused of the cloud of projects around Pharo and what thay can do. Maybe somewhere already exists similar list. Maybe in textual form. If so, please, post it to me. Image starts in the center where Pharo logo is. Around it, there should be a core of Pharo (included in the image). Outside of this core, there are other important projects and frameworks. Text in ovals should represent main concepts and around them there are names or logos of projects that are related to them. Text in rectangles should represents main attributes of nearby project. I would also like to draw bigger text or logos of projects that are very important (or enterprise ready...?). As you can see, it lacks lots of things (mostly because I draw it very quick and did not study every projects and every book about Pharo). But If anybody have anything to contribute, I will be happy to include them to this map. Maybe it will be also better to create this picture through some visualization based on descriptive syntax of this hierarchy map (like mind-mapping) :) Have a nice day, Adam.
