Smacc question
by Stephane Ducasse March 28, 2017

March 28, 2017

Hi john I'm learning smacc as a challenge :) I read a review the tutorial that we extracted form your doc. I have the following expression FunctionTypeName = 'function' TypeNameList ( 'internal' | 'external' | 'constant' | 'payable' )* ( 'returns' TypeNameList )? and I started to handle the 'internal'.... Now my grammar does not succeed to parse (self parser parseFunctionTypeNameOptions: 'internal payable') Attempt one: did not work =================== FunctionTypeNameOptions : {{}} | FunctionTypeNameOptions "internal" 'option' {{}} | FunctionTypeNameOptions "external" 'option' {{}} | FunctionTypeNameOptions "constant" 'option' {{}} | FunctionTypeNameOptions "payable" 'option' {{}} Attempt two: did not work =================== FunctionTypeNameOptions : | FunctTypeNameOptions ; FunctTypeNameOptions : FunctTypeNameOptions "internal" 'option' {{}} | FunctTypeNameOptions "external" 'option' {{}} | FunctTypeNameOptions "constant" 'option' {{}} | FunctTypeNameOptions "payable" 'option' {{}} ; Attempt three: did not work ===================== FunctionTypeNameOptions : | FunctTypeNameOptions ; FunctTypeNameOptions : FunctTypeNameOption 'option' | FunctTypeNameOptions FunctTypeNameOption 'option' ; FunctTypeNameOption : "internal" 'option' {{}} | "external" 'option' {{}} | "constant" 'option' {{}} | "payable" 'option' {{}} ; I studied the JavaParser and I do not get why my version does not work modifiers_opt : | modifiers ; modifiers : modifier 'modifier' | modifiers modifier 'modifier' ; modifier : "public" 'token' {{Modifier}} | "protected" 'token' {{Modifier}} | "private" 'token' {{Modifier}} | "static" 'token' {{Modifier}} ; Thanks in advance. I could have try to do it in petitParser but I want to have a real experience with Smacc. Stef

Creating Dates before/after Daylight Saving Time change
by Petr Fischer March 27, 2017

March 27, 2017

Hello, 1) when I create date on: 2017/03/20 (before Daylight Saving Time change) with this code: D1 := Date year: 2017 month: 3 day: 26. Date object is created with instvars: start: 2017-03-26T00:00:00+01:00 duration: 1:00:00:00 2) when I create same Date instance with the same code on/after: 2017/03/26 (after Daylight Saving Time change): D2 := Date year: 2017 month: 3 day: 26. Date instance with this instvars returned: start: 2017-03-26T00:00:00+02:00 duration: 1:00:00:00 3) D1 != D2 So, for example: persisted instance of date (Date year: 2017 month: 3 day: 26) created before DST change is not equal with date instance (Date year: 2017 month: 3 day: 26) created after DST change. DST change breaks equality of the same date :( Is it OK? Thanks! Petr Fischer

When I follow the procedure at https://github.com/pharo-nosql/voyage to install Voyage in a 4.0 image, it leads to an unfonctonnal Voyage (timeout on socket when doing a query) My configure baseline is just as simple as the one bellow.

March 26, 2017

sorry to abuse pharo list, but I guess it is related enough. Smalltalk made it to SO developer Survey. Unfortunately it did not appear in most used languages list, but it got great place as "Second most loved language"! So for those of you who participated in the survey, it payed off. davorin

Voyage Timeout
by Hilaire March 26, 2017

March 26, 2017

Hi, When I configure a production image with command st handler as following: pharo myImage st --save --quit configureMyImage.st I notice at image start up, a Socket timeout error. In the configureMyImage.st script, among other things, I open a singleton Voyage repository. I added a 5s delay at the end of this script, just wondering if image was shutdown before Voyage establishes connection with the Mongo DB, but no. Any incompatibility issues to be aware of between st command handler (particularly the --save part) and Voyage repository? Thanks, Hilaire -- Dr. Geo http://drgeo.eu

Voyage hang
by Hilaire March 24, 2017

March 24, 2017

>From a production image, built from script with the voyage configuration as: >"External PROJECTS dependencies" >spec project: 'voyage' with: [ > spec > className: 'ConfigurationOfVoyageMongo'; > repository: 'github://pharo-nosql/voyage:master/mc'; > versionString: #stable. > ]. The image is first configured and used to populate a MongoDB, but then when doing a simple #selectAll on a persisted class of objets the image hangs! It is really weird because the Mongo browser from the same image let me see my database objects. So the MongoDB connection should be fine. I can alt+. the image, so enclosed the debug log. Any idea or direction to look at? Thanks Hilaire -- Dr. Geo http://drgeo.eu

I am ready to deploy a live production application, and am exploring my options.. I currently host a bunch of other things over at Digital Ocean. I would like to use them for this project to, using a new droplet. Does anyone know if there is a quick and easy way to install Gemstone/s on the Digital Ocean server? I will also need to port Teapot to Gemstone/s.

Fwd: GSoC 2017: Tips on Reviewing Student Proposals
by Serge Stinckwich March 23, 2017

March 23, 2017

Dear all, this is a short update for the Google Summer of Code 2017. The students have to submit your proposals on the Google website before April 3rd. See details below. I dunno exactly who are the students/mentors who are submitting a proposal for Pharo. Can the mentors (or students) send me in private an email about the name of the students/mentors + a title of your project ? Thank you very much. Regards, ---------- Forwarded message ---------- From: Google Summer of Code <summerofcode-noreply(a)google.com> Date: Mon, Mar 20, 2017 at 7:26 PM Subject: GSoC 2017: Tips on Reviewing Student Proposals To: sergestinckwich(a)gmail.com [image: Google Summer of Code] Hi Serge Stinckwich, Thank you for registering to be a GSoC 2017 mentor or organization administrator! We have many new mentors and organizations this year so we wanted to go through some important details to help you understand the process for the next couple of months. Please take the time to reach out to your organization administrator about what is expected of you this year as a mentor. We also encourage you to read the entire Google Summer of Code mentor manual <http://write.flossmanuals.net/gsoc-mentoring/about-this-manual/> and the Roles and Responsibilities doc if you haven't done so already. Both the manual and Roles and Responsibilities doc were written by GSoC veteran Org Admins, Mentors, former students and Google Program Admins. They have helpful information about the program and how to participate successfully at each step in GSoC. *New GSoC Orgs*: the section about participating in your first GSoC has some great tips. To see all emails sent to mentors and org admins visit this page <https://developers.google.com/open-source/gsoc/2017/mentor-oa-announcements> that will continue to be updated throughout the program. Student Proposals As of today, students are able to submit their proposals via the website. Each student may submit up to 5 proposals to the program. They can submit multiple proposals to the same organization for different projects if they wish. Historically, the students with the best proposals reach out to the orgs early to receive feedback before submitting their final proposal. To encourage more students to seek feedback on their proposals we made draft proposals part of the official proposal workflow. Be sure to refresh your dashboard periodically so that you can see when new drafts are ready to review. You will not receive an email. We are encouraging the use of Google Docs for proposals as this will allow you to comment directly on the proposal (if the student sets their sharing settings correctly). Over the next couple of weeks you will be interacting with dozens and in some cases hundreds of students interested in working with your project. We know many of you may become overwhelmed and some students can be impatient, so you may want to have an auto-responder or some sort of canned response to let students know you are looking at their proposals but it could take X days to receive a response. Students *must* submit their final proposal as a PDF through the website. It will be visible to you after the deadline for student applications (April 3 16:00 UTC). You should make your decisions on which students to accept based on the contents of the final PDF proposal and your interactions with the student. Students can delete their proposals and you will not receive an email of the deletion. If a proposal disappears from your list, it is likely because they deleted it. Working with Students All student projects must have at least 1 mentor assigned to the project. We strongly encourage assigning a second mentor as a backup mentor or co-mentor. A mentor should not be the primary mentor for more than one or two students. Mentoring can be a lot of work and we donât want anyone to burn out and become frustrated with the program. Important GSoC 2017 Dates and Deadlines *March 20 - April 3 16:00 UTC*: Mentors and Org Admins review student draft proposals and give students feedback on their proposals. *April 3 - 16:* Review all submitted student proposals with your org and consider how many you want to select and how many you can handle. Decide on the minimum/maximum number of student slots to request. *April 17, 16:00 UTC*: Deadline to submit slot requests (OAs enter requests) *April 19, 16:00 UTC*: Slot allocations are announced by Google *April 19 - 24 16:00 UTC* : Select the proposals to become student projects. At least 1 mentor must be assigned to each project before it can be selected. (OAs enter selections) *April 24 - May 4:* Google Program Admins will do another review of student eligibility *May 4*: Accepted GSoC students/projects are announced *May 4 - 29*: Community Bonding Period *May 30*: Coding begins *June 26-30*: First evaluation period - mentors evaluate students, students evaluate mentors *July 24 - 28*: Second evaluation period - mentors evaluate students, students evaluate mentors *August 21- 29*: Students wrap up their projects and submit final evaluation of their mentor *August 29 - September 5*: Mentors submit final evaluations of students *September 6*: Students passing GSoC 2017 are announced Mentors Mailing List If you want to be included on the GSoC mentors mailing list be sure to opt in on your User Profile page. We will add anyone who has opted in to the list every few days for the next month. And then every couple of weeks throughout the program. You can always opt out once you have been added by unsubscribing using the link on any of the emails. Contact Us Please use the gsoc-support(a)google.com email address for questions so that anyone on our team can answer your question for you. We look forward to working with all of you over these next 6 months! Thanks again for being a mentor for GSoC 2017!
