glamorous toolkit: v0.4.0
by Tudor Girba Dec. 14, 2018

Dec. 14, 2018

Hi, Things are moving fast in the glamorous land. We now reached v0.4.0: https://gtoolkit.com There are several significant advances in this version. The first thing to note is that v0.4.0 is a reproducible version that can be loaded with: Metacello new baseline: 'GToolkit'; repository: 'github://feenkcom/gtoolkit:v0.4.0/src'; load. https://github.com/feenkcom/gtoolkit/releases/tag/v0.4.0 The version was created with Releaser the new member of GT that is able to release deeply nested projects: https://twitter.com/girba/status/1073407418460225536 The rest of the environment has seen a few key changes as well: - Documenter received support for dynamic markup edit. This is an almost magic ability that makes the markup appear when the cursor nears the markup. With this we have reached a seamless experience that supports both viewing without markup and editing on demand. https://twitter.com/feenkcom/status/1067879286143676419 - Playground uses Coder and snippets are now collapsable. https://twitter.com/feenkcom/status/1070806168459767809 - The Inspector updates when the code changes. https://twitter.com/feenkcom/status/1072581283925159936 https://twitter.com/feenkcom/status/1072107898900238337 - The Meta view from Inspector was enhanced to show the super classes and method categories, each of these act list filters. On top of that, we can also filter methods by name. https://twitter.com/feenkcom/status/1072223641583149057 A more complete list of issues we addressed is found here: https://github.com/feenkcom/gtoolkit/milestone/2?closed=1 Please do let us know what you think .. and, of course, what you feel. Have fun, The feenk team -- www.feenk.com âHow do you feenk today?"

Pharo 7 under Linux
by Konrad Hinsen Dec. 14, 2018

Dec. 14, 2018

Hi everyone, I haven't had much success running Pharo 7 under Linux as follows: Â 1. Install pharo-launcher Â 2. Start pharo-launcher Â 3. Create an image for the Pharo 7 development release Â 4. Start that image. It crashes at startup, claiming that libgit2 is missing. There is, however, a libgit2 located at Â Â $HOME/Pharo/vms/70-x64/lib/pharo/5.0-201806281256/libgit2.so Is this a known problem? Is there a workaround? Thanks in advance, Â Konrad.

Re: [Pharo-users] [ANN] Git Thermite integration with Iceberg
by Paul DeBruicker Dec. 12, 2018

Dec. 12, 2018

Please take this with a grain of salt and I'm not at all trying to do anything but be helpful and expose my confusion. It looks interesting but what are some use cases of Thermite? I don't have a real good sense of what kind of understanding it helps with. >From reading the github page I can see that I can get some visuals of what fraction of a package I've changed/touched in a commit or between two arbitrary commits. The documentation is understandable but is a lot of "what" & "how" and not a lot of "why" or "because" and so I have to try to come up with that on my own. I'm sure there's value there because its obviously a lot of work to get the project to this point, but I'm not able to make the leap there today. What changes in my behavior or process should I have or begin to think about as a result of seeing thses types of visualizations? I'm happy to fill out the form but "I don't 'get it' after looking at it for 15 minutes" doesn't seem like helpful feedback just yet. Maybe its intended to be more useful in teams and not so much for a solo developer. Also - I'm partially red/green colorblind. Where can I edit the colors to not use Red/Green?

Submitting HTML Forms
by Richard Kenneth Eng Dec. 12, 2018

Dec. 12, 2018

I'm having a lot of difficulty getting file uploading to work using Teapot/Zinc. The documentation is not entirely clear about how it's supposed to work, and the example provided doesn't quite work. I'm referring to section "4.6 Submitting HTML Forms" in "Enterprise Pharo â a Web Perspective." Here's my setup... I have a Teapot route like: GET: '/upload-handler' -> [ :req | self uploadHandler: req ]; where uploadHandler: req ^ '<div> <form method="POST" action="upload-handler" enctype="multipart/form-data"> <input type="file" name="fileupload"> <input type="submit" value="Upload!"> </form> </div>' I have a submission form like: GET: '/submission' -> [ :req | self submissionPage: req ]; POST: '/submission' -> [ :req | self handleSubmission: req ]; where submissionPage: req ^ '<div> <form method="POST"> <input type="file" name="fileupload" value=""> <input type="submit" value="Submit"> </form> </div>' handleSubmission: req ZnClient new url: 'http://174.117.171.194/upload-handler'; addPart: (ZnMimePart fieldName: 'fileupload' fileNamed: 'S1-ABCD012345.st' ); post. When I submit the submission form, I get "FileDoesNotExist: File @ /S1-ABCD012345.st". It doesn't matter what path I use to get to S1-ABCD012345.st. I tried "/Users/richardeng/Documents". I tried "/Documents". I tried "/". I don't know what path it's looking for. The file is there â there's no reason why it can't find it. I guess I'm just not understanding how this whole thing is supposed to work. Any ideas? Richard

[pharo7] loading mcz files

It appeared impossible to load any packages (mcz files) from a MCFileRepositoryInspector, in a recent pharo (moose) 7 image (on windows 7), stack below.

Reify RBLiteralNode and RBBlockNode args/return with MetaLink?
by Manuel Leuenberger Dec. 12, 2018

Dec. 12, 2018

Hi, I am currently playing with MetaLinks in Pharo 7 and stumbled upon some issues. For example, I found that instrumenting message sends may break compilation (see https://pharo.fogbugz.com/f/cases/22681/Metalink-on-message-may-break-compi… <https://pharo.fogbugz.com/f/cases/22681/Metalink-on-message-may-break-compi…>). Two other issues also arised: i) How do I reify the value of an RB(Valuel|Literal|LiteralValue)Node? RFValueReification does not work, and there is no reification for literal, value, or literal value nodes. ii) How do I reify arguments and results of blocks? I tried reify context for the block body #before and value for #after block "last", but I often run into the problem of no reification for literals. iii) How are cascaded message sends reified? Am I supposed to instrument the cascade node or the individual message sends? I am grateful for any pointers towards a solution. BTW, Marcus' lecture slides give a great intro to metalinks (http://marcusdenker.de/talks/18LectureMetaLinks/MetaLinks.pdf <http://marcusdenker.de/talks/18LectureMetaLinks/MetaLinks.pdf>). Cheers, Manuel
