git and metacello

by Yuriy Tymchuk

Hi guys! Sorry if Iâm bothering you, but I wasnât able to find any workflow or so on with git. Iâve started to use file-tree, but for now on I donât understand how to make it work with metacello. Also is there some project like that built on jenkins, so I can set up similar job. Cheers Uko

Nicolas, Would you mind putting this in a configuration so that we can load it easily in 3.0? I agree with you that this parsing story should be as best as possible. And it is not so right now. Phil

For me, providing a way to parse very simple objects like numbers dates etc... from a string representation SHOULD be a core service. And, indeed, IT IS the #readFrom: API. For dates, there is a well known exhange format, so that's what we can use. For numbers, less so, but most other languages either share sufficient coverage of literal syntax, or provide common libraries for such parsing (like scanf etc...) If you provide a limited API (limited to Smalltalk literal syntax, Squeak/Pharo dialect), then it's sufficiently different from the rest of the world to require extension from app. developpers POV. So you put the burden on application developpers which will re-program the same micro-package again and again. Since it is a micro-feature, this will lead to a balkanization of micro packages, several packages doing more or less the same, more or less correctly. And concerning conversion of Float from decimal->binary representation, it'll be less ciorrectly, indeed it's very easy to do it wrong (not correctly rounded). 10 years ago, every SMalltalk dialect I know of did it wrong in any case... That's also why it should be a core service, and why it is in other languages (via scanf or other library) Back to the implementation, the decision for reifying the NumberParser was precisely: - to correct the parsing of Float which requires a little care to be correctly rounded (what every other language does right, Smalltalk did wrong) - to refactor a bunch of readFrom... selectors spreaded along the number hierarchy. - to correct discrepancies between the readFrom... variants (handling of separators, extra characters, error handling) So was it a good idea to factor Number parsing from several format? I cna agree on critiscism about the implementation: the NumberParser are ad-hoc hand crafted disconnected from grammatical formal description... Maybe what we need is a lower level service on which to build DSL parsers... But in any case, I think it's already better than what we had a few years ago.

Maybe you can do a screencast movie about it yourself. It is actually very easy on Mac OS X. Start QuickTime Player, goto File > New Screen Recording, select full screen or a smaller area, and start recording. You stop by clicking the extra icon in the top right (as you can see at the end of my movie). You can then just upload that movie to YouTube directly. I would suggest not using the huge screen size of a Cinema display, but to temporarily switch to a lower resolution like 720p (System Preferences > Displays > Resolution [Scaled]). I did the Windows 8.1 movie using VirtualBox on the Mac, BTW.

Re: [Pharo-dev] Pharo-Business: a new mailing-list

by Sebastian Sastre

I applaud the initiative. Business and connections is the point. Also connecting with business. Yesterday I was in http://www.startupfoz.com/ and talked with many people about startups and investing an technology (and doing business with technology). One of the guys I talked to was from the TI-APL (Productive Local Array of TI companies) and they told me they started having meeting with no idea of what they were doing nor what to do. One of the companies that belong to this array has 5000 employees and produce software for all around the globe and being in the array puts you at 1 hop of social distance of top notch connections and strategic business advice. Do you know what theyâve said to me after 5m talk? We need more people with your thinking in the APL, last year we didnât even know what a startup is, you can help us get were are we going. Today theyâre the biggest APL of TI companies in Brazil and because they have become so big they are consulted on budgetary decisions from time to time. Thatâs how theyâve ended up sponsoring StartupFoz. Now if that happened to me in one of many casual talks in a meetup, the questing I want to leave here is this: how many other smalltalkers anywhere can get into positions of influence? When you listen first, people listens back and you might be surprised by how they react when you explain things making sense. We might have no idea now about the point But connections and business is the point Also connecting with business is the point People are socialising technology and coding already to bootstrap their next businesses: https://koding.com/ So if we donât do that with the smalltalk spiritâ¦ who will?
