HI alistair this is supercool that you push this! I mean it for real. Because this simplnk stuff was always getting on our way for scripts. This is really great to see this happening.

Re: [Pharo-dev] New Launcher not working (Windows)

tx christophe. Launcher is cool and this is nice to see some effort on that front.

Re: [Pharo-dev] Is there a portable way to check if a string is a block?

by Nicolas Cellier

Presumably, you must parse the string (not evaluate), obtain an Abstract Syntax Tree on return (or an Exception), and check that this AST conforms to some pattern (at worse you code naÃ¯vly the pattern matching, at best you can reuse the refactor/rewrite engine). I've not followed latest Compiler developments, but from what I understand, more and more tools are based on AST... so it sounds pretty straight-forward. 2017-07-24 18:21 GMT+02:00 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi guys, > > Is there a portable (that would work in GemStone too) and safe way to know > if a String would be a block? > > I must support this kind of strings: > > 'singleString' -> false > 'multi string' -> false > ' [:a | 42]' -> true > ' '' '' [:a | 42]' -> true > '[:a | 42]' -> true > ' "a commet" [:a | 42]' -> true > ' WhateverClass someVeryBadHackishMethod.

by Tim Mackinnon

This is a great step to show we have a stable consistent base for the year ahead - thanks for pulling this off! One small caveat on the 64bit angle - there are still some known outstanding bugs with 64bits - meaning that Fuel is known not to work (which might be for more specialised things - but it does mean we have to careful about how 64bits its advertised : https://pharo.fogbugz.com/f/cases/20120/Fuel-is-not-64bits-ready <https://pharo.fogbugz.com/f/cases/20120/Fuel-is-not-64bits-ready> https://pharo.fogbugz.com/f/cases/20119/ <https://pharo.fogbugz.com/f/cases/20119/> ) Tim > On 24 Jul 2017, at 12:56, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > > Hi, > > We are releasing Pharo 6.1. > Usually, between each major version we just apply bugfixes changing the build number and not announcing new versions but this time is different since the fixes applied required a new VM. > The principal reason for the new version is to update Iceberg support, bringing it to macOS 64bits version. > > So, now Pharo 6.1 comes with Iceberg 0.5.5, which includes: > > - running on macOS 64bits > - adds cherry pick > - adds major improvements on performance for big repositories > - adds pull request review plugin > - repositories browser: group branches by remote > - adds bitbucket and gitlab to recognised providers on metacello integration > - uses libgit v0.25.1 as backend > - several bugfixes > > Other important change: > > - linux vm by default is now vm threaded heartbeat. > > We still miss 64bits Windows (sorry for that), but we are getting there.

Is there a portable way to check if a string is a block?

by Mariano Martinez Peck

Hi guys, Is there a portable (that would work in GemStone too) and safe way to know if a String would be a block? I must support this kind of strings: 'singleString' -> false 'multi string' -> false ' [:a | 42]' -> true ' '' '' [:a | 42]' -> true '[:a | 42]' -> true ' "a commet" [:a | 42]' -> true ' WhateverClass someVeryBadHackishMethod. [:a | 42]' -> true I need to identify whether the string is a closure or not. And ideally, I don't want to do an #evaluate: because I don't want any left hand code to be executed. I tried with #parse: why I am having problems. Any ideas? Thanks in advance -- Mariano http://marianopeck.wordpress.com
