Hi Peter and Stef, Sounds like you want a XML Digester? This is the one in Java: https://commons.apache.org/proper/commons-digester/ May be you want to check as reference.

Re: [Pharo-users] Use Shell Command from Pharo

by Dale Henrichs

I seem to recall that on the mac there was a system option of some sort that "launches apps from a sensible" location --- of course the Apple powers that be may have removed that capability recently...

You'll see that GUI-launched images do not inherit your shell environment either. However, if you run pharo from command-line, you get the usual unix behavior. > On Linux you get home, although that's imho also wrong and it should use > the folder of the imageâ¦ but maybe that's a misconfiguration of OSProcess. > No, it's the same logic than on Mac (albeit $HOME is arguably a little more sensible than the filesystem's root). I'm not sure what's the correct behavior here, unless there is a way to know if pharo was launched from GUI (where working directory is meaningless and pharo should probably chdir() to the image directory) or from command-line (where the working directory is meaningful and should be honored. On OSX, maybe there's a way to pass GUI-specific arguments, through the Info.plist file?

Re: [Pharo-users] Generating custom classes based on attributes from XML Document

by stepharo

We had great fun with peter because I could understand what I was looking for around my xml importer. Peter has the same problem so it was fun that we can talk and see the light. What we learned in the process is that the pluggable behavior is nice but limited - type of matching - you cannot match on children because you did not created them yet :) So what we plan to do and started (peter publish your code :) - have a naive visitor on XMLNode - use it to write a transform visitor that turns such some nodes into special "domain nodes" - Define a builder generating visit methods for an exporterVisitor visiting the "domain nodes" (this phase can be really automated) - The exporterVisitor will let the programmer to define export rules and create Pharo Object and moose objects. Peter if you find something useful in C# let me know.

Yeah if we redesign the String API it should account for Arrays and probably other kinds of sequences tooâ¦ On 19 March 2016 at 11:28, stepharo <stepharo(a)free.fr> wrote: > copyFrom:to: > > Stef > > Le 19/3/16 11:22, stepharo a Ã©crit : > > Hi >> >> I have an array and I would like to extract a segment of elements and I >> did not find >> >> array from: start to: end >> >> Did I miss something obvious? >> >> Stef >> >> >> > >
