Re: [Pharo-dev] New methods for the String class

Sure, the hardest part of the work is not really about implementing the functionalities, but providing good method names, good comments and relevant examples.

GTPlayground

by Alexandre Bergel

Hi! Now I am back from holidays, I am catching up with what happens during that February. My first surprise is GTPlayground, packaged with the Moose image. This is really cool stuff. I have never thought that the workspace could be such a primitive tool. GTPlayground greatly enhances my workflow when I am in a workspace. Managing variables is still missing apparently, but this is clearly a great match with my dream of a cool Pharo.

Re: [Pharo-dev] New methods for the String class

Daniela you should try the method finder open it and select the example in the dropbox then you can type examples and see if a method already implement it for example âabcabâ . âaâ . âbcb' shows that copyWithoutAll: is the method. but it expects a character as second argument âabcabâ . $a . âbcbâ Stef On 24 Feb 2014, at 18:30, Daniela Meneses <daniela11290(a)gmail.com> wrote: > Hi to all, > > As you may know I'm working on in some improvements for the String class.

Re: [Pharo-dev] Authorize upArrow in binary symbols

The base level should be extremely flexible (to the point that to you can break *any* Smalltalk convention). Any kind of checks for âbest practicesâ should be done on level up on the tool level, and even there only if really needed. (in the past we had the idea to provide feedback e.g. to not have instance variables with capital letters, but this should *never* be enforced on the low level, as for DSLs, research hacks and real cool stuff (TM) people need all flexibility) Pharo uses (right now) RBParser as the main Parserâ¦ in Pharo4 we will remove the old Parser (subclass of Scanner ;-), on the TODO is to check if PetitParser can be used instead (but there are many open questions related to e.g. error handling, speedâ¦) Marcus

collecting Pharo Youtube videos...

by Marcus Denker

Hi, There are a lot of videos on youtube about pharoâ¦ from conferences, demos, jamesâ Smalltalk4U, fosdem, ESUG, and others. I am (very slowly) adding playlists for all of them to the Pharo Youtube channel: https://www.youtube.com/channel/UCp3mNigANqkesFzdm058bvw/playlists If you have videos that you want to see added, send me a mail. The channel itself is here: https://www.youtube.com/channel/UCp3mNigANqkesFzdm058bvw It could use some more subscribers ;-) Marcus
