Pharo on Mac
by Hari Balaraman Oct. 8, 2016

Oct. 8, 2016

Hi All, Fyi- the Pharo default collection of downloaded files for MacOS does not work (starts up with blank screen and remains as such) on MacOS Sierra. On another Mac with the previous OS (El Capitan) the default download works.

[ANN] Tealight
by Torsten Bergmann Oct. 8, 2016

Oct. 8, 2016

Hi, I wrote a small extension "Tealight" for the Teapot framework that makes it even easier to experiment with web based interfaces/web calls into Pharo running on the server side. It additionally allows you to easily define and generate a simple or versioned web interface for your own apps. With this extension REST annotated methods like greeting: aRequest <REST_API: 'GET' pattern: 'hello'> ^'HelloWorld from Pharo' are transformed into dynamic Teapot routes and can be accessed easily via web. You can use two pragmas: #REST_API:pattern: for standard APIs #REST_API:versions:pattern for versioned APIs Full docu explaining how to use it is added on https://github.com/astares/Tealight It also shows the new custom "Teaspoon" inspector extension tool implemented by Attila Magyar - which is really cool to experiment and call the web methods without a web browser or Zinc scripts. So far there is no config for Tealight for the catalog yet, will add this soon. So for the time being you need to load the latest version via Metacello new repository: 'github://astares/Tealight/repository'; baseline: 'Tealight'; load to follow the docu description. Have fun! Bye T.

Spec: scaling imageModels
by matteob8 Oct. 8, 2016

Oct. 8, 2016

Dears, I'm experimenting with Spec, more specifically with a ImageModel. I'm tring to scale the image accordingly to the window size, but I can't find a simple way to do that. Does windows resizing trigger a "when..." message? Should I try a different solution? Thanks, Matteo -- View this message in context: http://forum.world.st/Spec-scaling-imageModels-tp4918439.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

GitFileTree-MergeDriver and using it with git mergetool
by Holger Freyther Oct. 4, 2016

Oct. 4, 2016

Good Morning, Thierry Goubier has merged a change to use the Pharo "merge" as a tool for "git mergetool" and in this mail I explain how to configure it, give a small example and explain my usecases for it. I am not sure the merge is fully working and would like people to test and review (code and merge results). Configuration: edit ~/.gitconfig and put something like: [mergetool "mcmerge"] cmd = /path/to/GitFileTree-MergeDriver/merge --mergetool $BASE $LOCAL $REMOTE $MERGED Usage: $ git mergetool --tool=mcmerge Use case: When using git merge to merge n branches, the GitFileTree-MergeDriver will be consulted to merge the configured files. The same tools are not used when git cherry-pick and git rebase fail to merge. In these case a manual call of "git mergetool" is required. The following cases might be something you encounter. If you maintain a stable branch but want to backport a specific bugfix from a master branch you might use "git cherry-pick <FIX_FROM_MASTER>" and end with a merge conflict on the metadata. Using git mergetool --tool=mcmerge will help you to resolve it. You try to contribute to a project that is using git for hosting and have either been asked to modify your commits or the master version has been updated while your code was under review. In this case you would issue "git rebase origin/master". Metadata merge conflicts can be resolved with git mergetool. For work I was creating a bugfix but when thinking of deployment I noticed that I need to deploy in two phases. Roll-out the initial part of the fix and once it runs everywhere start rolling out the actual bugfix. What I did was splitting my bugfix branch in two, merge the first part into repository. After it has been merged other changes were made before the update was deployed. To continue to work on the second part of the bugfix I rebased it and have used git mergetool to merge the metadata. cheers holger
