OSProcess lock image
by Hilaire Dec. 12, 2017

Dec. 12, 2017

Hello, On Pharo4, when I type the command: OSProcess waitForCommand: 'ls' it locks the image, I can get back control with [Alt]-. With the same image and VM, this command was previously working, even called from a Seaside component. Any idea? Thanks Hilaire -- Dr. Geo http://drgeo.eu

How to deploy headless app without changes and source files?
by Andreas Sunardi Nov. 19, 2017

Nov. 19, 2017

I found this StackOverflow question: https://stackoverflow.com/questions/14737695/is-it-possible-to-deploy-a-pha… and this older forum thread: https://www.mail-archive.com/pharo-project@lists.gforge.inria.fr/msg21170.h… I'm using Pharo5.0 and neither of these options is available anymore. What is the new way to do this? -- Andreas Sunardi

[ann] pillar text editor
by Tudor Girba Nov. 15, 2017

Nov. 15, 2017

Hi, Pillar now ships with a text editor that also features a syntax highlighter. So, now, if you load the development version of Pillar: Gofer new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration; loadDevelopment. You will have an extra presentation when inspecting a .pillar file: The new thing here is that the highlighter is based on the Pillar PetitParser, and it is extensible for highlighting more parts if needed. The highlighting also can support actions. For example, the picture above shows the file to the right after clicking on the reference. Please take a look and let me know what you think. Cheers, Doru -- www.tudorgirba.com www.feenk.com "Things happen when they happen, not when you talk about them happening."

including Pillar in Pharo image by default
by Peter Uhnak Nov. 10, 2017

Nov. 10, 2017

Hi, I would like to propose including Pillar in the Pharo image by default. My reasoning: Since we are moving to git, and most people will use github, gitlab, and the likes, it is expected to include a README.md file (or possibly more extensive documentation) alongside the code. Which means that people will (and are) writing the README mostly by hand, which of course is problematic, as e.g. code snippets can get deprecated, screenshots become outdated, etc. As Pillar tries to address these problems, it would make sense to me to include Pillar in the image by default, as anyone using git (which eventually should be everyone) will most likely benefit from writing their documentation in Pillar. Similarly using Pillar would open an avenue to provide the documentation in-image, e.g. one exporter for html/markdown, and another one for Pharo's Help system. I could, of course, install Pillar every time, but considering thats extra effort and in the extra time I can fix the issues by hand, I don't have such an incentive to use Pillar for this. Questions & Problems: I don't know by how much would pillar increase the image size. Perhaps there could be (a) "lightweight Pillar" (that would include just pillar & markdown exporter), or (b) we would have different images for different uses. By different images I mean something along the lines of a) developer image - meant to be directly used by developers to create their software b) production image - as a foundation for running systems / users Does this make sense?

I recently discovered the pharo launcher. However, it only gives me options to use outdated images, and I'm not sure about the vm. Is there any way to change this?

Object>>#name deprecated in Pharo 6 -- what do I need to do?
by H. Hirzel Sept. 11, 2017

Sept. 11, 2017

Hello In the last days there was a discussion that Object>>#name should no longer be used. I did not follow the discussion in detail. What was decided how #name should be replaced? What do I need to do if I get a deprecation warning [1]? Thanks for the answer in advance Hannes [1] The method Object>>#name called from PPCMNode>>#gtTreeViewIn: has been deprecated. Implement your own domain representation of an object, or use #asString or #printString instead. Select Proceed to continue, or close this window to cancel the operation.

#parseMethod:onError: isn't as obvious as expected - is it me?
by Tim Mackinnon Sept. 11, 2017

Sept. 11, 2017

Iâm looking for some feedback on the usage of RBParser>>#parseMethod:onError:. I am looking at ways of improving the way we edit code - and making things work (as least for me - but maybe for everyone) a bit more like IntelliJ where they have some great code operations and very good keyboard support. We are certainly close, but at times feel a bit clumsy - which is a shame as we have far better infrastructure to support equivalent features. So I thought I would have a go. Anyway - step one (which I think Iâve come close on), was to teach senders/implementors to look at the AST so you donât have to highlight exactly what you want to search on - instead it can infer from your cursorâ¦ however my next step was to improve how we can select code to ease refactoring, bracketing etcâ¦ So this is where Iâve hit a few issues which strike me as confusing (and I will freely admit that Iâm not a mega compiler, parser guy - but Iâd love to beâ¦). The following code blows up strangely - and I think its very confusingâ¦ as it turns out that #parseMethod:onError: doesnât work like I would expect (and this is where Iâm after feedback). It seems that the onError block doesât actually exit parsing - it takes the result and then keeps running with something in an intermediate state - thus below, when I try to parse with a subset of the code (and maybe this is a naive approach to handle the case when you start typing code in the middle of a complete method, but want to parse it before youâve entered a final â.â or â;â) - you actually end up with an AST that is using all of the source code because the result of the error block is then applied inside the executing method. I find this very confusing? There are no comments in this code, and for me the convention of onError: is to execute in isolation unless there is a parameter that the error block can interact with. Iâm wondering if those with more knowledge agree - or if it is my naivetÃ©? This was my original code (and yes it needs refactoring a bit) - but anyway: bestNodeInTextAreaOnError: aBlock "Find the best node in the editor text area at the current pointer location" | ast start stop node source | start := self textArea startIndex. stop := self textArea stopIndex. source := self textArea string trimRight. ast := RBParser parseMethod: source onError: [ RBParser parseExpression: source onError: [ source := (source truncateTo: stop) trimRight. RBParser parseMethod: source onError: [ RBParser parseExpression: source onError: aBlock ]]]. stop > source size ifTrue: [ start := stop := source size]. node := ast bestNodeFor: (start to: stop). node ifNil: aBlock. ^node But this doesnât work, as âastâ is incorrect when it parses truncated source. To work around what Iâm seeing I have to instead extract the ast assignment to another method that looks as follows - but to me it seems very unexpected to have the explicit ^ statements? agressivelyParse: source at: loc "Find the best node in the editor text area at the current pointer location" ^RBParser parseMethod: source onError: [ ^RBParser parseExpression: source onError: [ | reducedSrc | reducedSrc := (source truncateTo: loc) trimRight. ^RBParser parseMethod: reducedSrc onError: [ ^RBParser parseExpression: reducedSrc onError: [^nil]]]]. This forces the ast to be exactly what I would expect - but Iâm wondering if I am missing something obvious? Tim

Pharo 6 FileSystem>>changeDirectory: is missing
by Andreas Sunardi Sept. 9, 2017

Sept. 9, 2017

I found FileSystem class has changed from Pharo 5 to Pharo 6. I've been using FileSystem>>changeDirectory to make my program (Pharo 5) runs in the current working directory (thus able to find local files). This is now broken because #changeDirectory doesn't exist anymore. The change seems intentional. Question: Is there a different way in Pharo 6 do set working directory or is this a bug? -- Andreas

The Spec UI Framework. first translation to korean finish.
by peter yoo Sept. 5, 2017

Sept. 5, 2017

hello. for pharo guys. Long time no see. It is not easy for Korean people to study pharo. Very few people use smalltalk. Of course, it is hard to find Korean language resources. Recently I went to find the spec framework to study Pharo. Of course I looked at morphic designer in squeak, but I believe in pharo team. I have translated it with the help of google for those who want to study. I refer to the pillar source of git. I wanted to work with pdf, but I know xetex, but I do not know about pillar and luatex. So I put it on the wiki. Thank you for always making good pharo. http://trans.onionmixer.net/mediawiki/index.php?title=TheSpecUIframework -- http://lookandwalk.com http://looknw.com | http://onionmixer.net peter yoo(Jonghwa Yoo).
