Re: [Pharo-dev] [Pharo-users] including Pillar in Pharo image by default

again, I think this is a discussion for pharo-dev. Please keep it there (is good discussion, btw ;) ). What about my proposal of including a tiny PetitParser?

I think with Pillar, it was more that things like headers, bold and italics are similar concepts but just use different characters - so I keep typing the wrong thing and getting frustrated particularly when we embrace Git and readme.md is in markdown. >> >> >> Tim >> >>> On 13 Aug 2017, at 20:08, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: >>> >>> Hi tim >>> >>> I personally do not care much about the syntax but I care about what I >>> can do with it >>> (ref, cite, ... ) >>> I cannot write books in markdown because reference to figures!!!!!! >>> were missing. >>> >>> And of course a parser because markdown is not really nice to parse >>> and I will not write a parser because I have something else to do.

PharoJS crashes at first try
by Frank-B Aug. 14, 2017

Aug. 14, 2017

As recommended here: http://forum.world.st/Anybody-using-Orca-Smalltalk-to-JavaScript-td4960519.… by @Serge, I loaded the code and tried to run it. But, I almost tend to say "as usual", *it fails at first try*! I "did" the code in the Playground window but nothing happens, no code is written into the selected directories. When I do "inspect it", I get a window (see screenshots), which does not really tell me either, what has happened (due to my lack of Pharo knowledge). Despite my over 20 years of full-time Smalltalk development, I have NOT any experience with either Squeak nor Pharo and most of my attempts to use them were very frustrating. Also, I do not feel like trying around, if and because: - even the very first test fails immediately - there is no meaningful documentation available - the classes I looked at were all undocumented (for me, a 100% no-go, never ever acceptable) And then, of course, also the test cases fail, because there is nothing in the diretories, where some earlier output was expected. Pardon, but professionality and confidence causing systems look very different too me. I am writing this with sadness, because it is certainly not my first such experience in the Squeak/Pharo area. There are some very bright people engaged here, but for some reason many of them lack some important aspects to be called professionals. Just FYI: My very first application software, an "ERP" system, which I started developing more than 35 years ago in horrible Basic, is still feeding a company (not mine) with >25 people as their sole product and has a couple of hundred business users. Some of my former staff is still working there and they said, this is only possible because I did force them "dictatorially" to document / comment every single line of code. In the beginning, they hated me for that. Today they are very thanksful. P.S. I DO have a very fast horse, because this is what one needs when telling the truth - in these days when truth is the worst "hate crime". -- View this message in context: http://forum.world.st/PharoJS-crashes-at-first-try-tp4960686.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Little article: keep your pharo repository in sync

This little article explains how you should keep your branches in sync with iceberg or (in worst-case scenario) from the command line. https://github.com/guillep/PharoIntegrationProcess/wiki/Keep-your-repo-in-s… These are the things I do all the time, if you have other cases, or you want to add anything, just tell.

Serializers/Encoders
by henry Aug. 14, 2017

Aug. 14, 2017

I find I do not necessarily have a specific question regarding a specific implementations, but a higher-level question of feasible solution. I need substitutable, type-relevant JSON encoding, perhaps based upon JSON Schemas. I am looking at ASN1Modules & types, Fuel clusterings/substitutions and NeoJSON clusters & mappers. Is it feasible to bring all these together? I would use ASN1Types, Fuel graph walking/substitutions and NeoJSON encoding and cluster hooks. Fuel also has Clusters but I see that Fuel encodes these clusters in each encoding. I am torn about this philosophically: good to have self-describing data encoding, but not suitable for JSON, unless just a type-name extension. Lightweight & robust descriptions? Well, this is all Fuel cluster specs within the encoding really is: a type-specification. The aspect of NeoJSON that has me wondering is the lack of polymorphism in type-spec lookup and recursive substitution. This is where Fuel shines, I feel. So what is the vision of the end state encoder? Use ASN1 Types as cluster descriptors, Fuel proxification on materializations and NeoJSON encoding and mappers. Would you have for me guidances in this area? - HH

Perhaps you might want to explain to me the return on investment of the Orca documentation then? Zero users, zero return on investment. I feel annoyed if you talk in absolutes like that, because I know that there are lots of situations where creating documentation is a waste of effort. And I have also been bitten by lack of documentation. And I have even been in a situation where both happened at the same time, where a lot of effort was put in creating the wrong kind of documentation. Oh, and I even wrote a bit of documentation myself. I have been thought many things at university, and there were many more things I had to learn in industry. And from open source projects, which have other things to teach. Investing means making decisions. Fully documented non-working code has no value. Working code that no-one can use neither. Your current communication is manipulative: you try to put yourself in a dominant position by using absolutes, saying you feel sorry for me, and bragging about your experience. That annoys me. If you want to convince me, use arguments. Stephan https://en.m.wikipedia.org/wiki/Nonviolent_Communication
