Re: [Pharo-dev] Integration process in presence of "external" project

by Esteban Lorenzano

I will soon release a âversioner commit toolâ who will help with this. The process will remain as now: you do your changes you do âcommit version of Xâ (where X can be from âRubricâ to âGTSpotterâ (and in the hopefully not far future even âNautilusâ or, why not âPharo-IDEâ or even âPharoâ) tools will collect packages and configurations and generate new ones, using semver nomenclature. finally, you will copy your âmainâ configuration (the root of your change) to the inbox (same as now). this is the beginning of the end of SLICEd based development. and this is the beginning of a modular era :) This is almost ready and is a good example of incremental changes that produces a fundamental lap (remember ânomads do not build cathedralsâ talk from Marcus): - gofer allows the scripting of commit and load packages - metacello allows us to declare and manage dependences - versionner does a very good job maintaining metacello configurations - version commit tool will allow the automation release pacthes for nested configurations Esteban ps: and when I said almost ready, it is for real: I hope to release an alpha version for testing tomorrow :) pps: sounds bad to put this last tool in the list to the big contributionsâ¦ at the end, is just a small tool on top of really important projects :)) > On 27 Apr 2015, at 21:39, Sean P.

Tool-TxWorkspace-TheIntegrator.6 is the version in Pharo 5.0. Its ancestor, which I wanted to copy to the TxText repo, is Tool-TxWorkspace-TorstenBergmann.5. I couldn't find it anywhere. I checked the Pharo40, Pharo50, and Pharo/TxText repos; and then started checking others e.g. sig/TxText. Eventually I found it in the Pharo40Inbox, copied it over, and updated the config. So, for external projects, simply taking changes from the inbox and integrating seems to be a little lacking.

Re: [Pharo-dev] [NB] NBExternalArray not working for complex types?

Right. So space is allocated for the constant sized objects or the pointers but not for the variable sized objectsâ¦ That explains what Iâm seeing with the memory being used sometimes. I guess allocation and finalization can easily be done in a dedicated subclass, so Iâll try that. Thanks a lot Henry!

By using 'char *â or 'NBExternalAddress' as type and then converting back to a String by sending #readString to the address. My current solution acutally does that but it seems that the allocated memory is being freed sometimes without my doing, so Iâm trying to let NBExternalAddress do as much as possible for me. > > > Iâd appreciate it if someone (Nicolai?) could take a look at NBExternalArray>>emitRead / emitWrite and see if thereâs an easy solution.

Pharo 4.0 - display

Oh well, that's better than having artefacts (to use correct terminology) from my point of view in the mean-time. No, there isn't pixilation. Thanks.

Are these changes good enough

by Sergio Fedi

Hi, I'm new to the Pharo community and recently installed Pharo 4.0. While using it I've found that the TestRunner didn't have coverage and after investigating a little I've found that is was almost there and I made it work. Is this change something I could submit as a Fix? (as per in http://pharo.org/contribute-propose-fix)
