Re: [Pharo-users] Modify AST to send a message on Character nodes

by Peter UhnÃ¡k

If you don't want to manually operate on AST, you can use Mark's Rewrite Tool ( http://screencast.com/t/LCEl0hFl , https://medium.com/@peteruhnak/using-rewrite-tool-for-fixing-deprecated-cod… ) As for ASTs I would be also curious about the answer, as this seems like it should be a simple task.

Modify AST to send a message on Character nodes

by Julien Delplanque

Hi everyone, I would like to modify the AST of a smalltalk expression compiled to automatically send a certain message when a node represents a Character (so the user does not have to write the message sending explicitly). I would of course add a special button in the menu you get when right clicking in a playground so the user knows it is a "special" do-it... For example: $a. would transform into an ast that the source code looks like $a aMessage How can I do this? :) Julien

Something like pipeup.io?

by HernÃ¡n Morales Durand

Hi, We are starting a project here which involves executing scripts in a (remote) CentOS HPC environment I have built. The stack is going to be Pharo + Seaside + QCMagritte + Voyage. The bash scripts could take a long time to finish, besides they are in beta state so I want to monitor a RT log of what's happening. Like this solution: http://pipeup.io/ Do we have something like that in Pharo? I read Zinc/Swazoo supports web sockets but I would like to read experiences or recommendations (links?). Cheers, HernÃ¡n

Re: [Pharo-users] load directive

by Dale Henrichs

Usman, Off topic --- I don't read all of the pharo posts on both pharo lists, but if you put Metacello in the subject, I have an email filter that alerts me and I read those (more often:) ... What you are getting with record is what would be loaded in the image, so my guess is that in Pharo4.0 there are equivalent or later versions of all the packages that would be loaded ... If you are interested in seeing all of the packages that would be loaded (without regard to packages already loaded in image) you can do the following: ((ConfigurationOfGlamour project version: #stable) ignoreImage: true) record loadDirective Dale On 09/11/2015 01:44 AM, Usman Bhatti wrote: > Tx for looking. > > I did: > (ConfigurationOfGlamour project version: #stable) record loadDirective > in Moose 5.0 (pharo3) and Moose5.1(pharo4). > > Here is the difference in the output.

Speaking of Roassal, I'm sure that if I start developping on it, after a week, I'm out of sync for at least ten version of it and unable to merge back my fixes in it, and that would be with Smalltalkhub. Me on a git workflow with Roassal? Piece of cake. Remember that you work differently on git and over smalltalkhub. In Smalltalkhub, you avoid branches and have only one master; in git you'll have plenty of branches and avoid doing work directly on master, because of the out of sync effects (and frequent merges).
