Building a Baseline
by Prof. Andrew P. Black Dec. 4, 2017

Dec. 4, 2017

In the baseline configuration of my project, it says spec baseline: 'SmaCC' with: [ spec repository: 'github://apblack/SmaCC:working' ]. Later, I have a parser that depends on 'SmaCC'. However, when I load my baseline, it seems to load from the current branch of the local clone of apblack/SmaCC in my file system. That is, my local clone was on branch master, so master was loaded, rather than working. What am I doing wrong, and how do I fix the baseline so that the correct branch is loaded? Andrew The complete baseline is as follows: baseline: spec <baseline> spec for: #'common' do: [ spec baseline: 'SmaCC' with: [ spec repository: 'github://apblack/SmaCC:working' ]. spec baseline: 'FileDialog' with: [ spec repository: 'github://peteruhnak/file-dialog/repository' ]. spec package: 'Grace-Scope'. spec package: 'Grace-Names' with: [ spec requires: {'Grace-Parser' . 'Grace-Scope'} ]. spec package: 'Grace-Parser' with: [ spec requires: {'SmaCC' . 'Grace-Scope'} ]. spec package: 'Grace-IDE' with: [ spec requires: {'FileDialog' . 'Grace-Compiler'} ]. spec package: 'Grace-Compiler' with: [ spec requires: {'Grace-Parser' . 'Grace-Names'} ]. spec package: 'GraceTests' with: [ spec requires: {'Grace-Parser' . 'Grace-Names'} ] ]

How to remove method body?
by Stephane Ducasse Dec. 4, 2017

Dec. 4, 2017

Hi to prepare some code for students I want to convert methods into a kind of method skeleton ie printOn: aStream "super nice comment" lk;lk; kl;;kl k;lkl;k ^ 42 into printOn: aStream "super nice comment" ^ self any idea? In the past I know that we could access the method comment but I do not find how to access the method signature (selector + variables). So I'm trying at the AST level. ((ObjSkeletonMock >> #methodToSkeletonize2) ast body: (ObjSkeletonMock >> #returnSelf) ast body). But I do not get how I can recompile this. Stef

Is there some concept this > wouldn't cover? There are two distinct issues. (1) Can this file name be put into a form that would have the same reference as the original whatever the state of the file system? (That is, whatever the same of the file system, the original name and the new form will reference to the same thing or neither will refer to anything, as long as I don't change directory.) For this, it _is_ safe to collapse // to / (except at the beginning) and to elide "." entries, but because of symbolic links it is *not* safe to elide ".." entries. (2) Give me an absolute path name that does not contain any symbolic links and will refer to the same file as long as no directories along the way are renamed or deleted. There is no POSIX function to do (1). The POSIX function that does (2) is realpath(2). If the Smalltalk method is intended to have the same semantics as the realpath() function, it should have the same name, possibly spelled #realPath. There is a Solaris function called resolvepath() which is subtly different from realpath() and not generally available.

Glorp v130 call for testing
by Alistair Grant Dec. 3, 2017

Dec. 3, 2017

Hi Everyone, I've merged the changes in: - Glorp-HerbyVojcik.127 and - Glorp-AlistairGrant.129 into Glorp-AlistairGrant.130 127 and 129 were both based on 126, but had diverged. This brings them back together. The new version can be loaded using #development, e.g.: Gofer it smalltalkhubUser: 'DBXTalk' project: 'Glorp'; configuration; load. (#ConfigurationOfGlorp asClass project version: #development) load. If you are using Glorp, I'd appreciate it if you could test this and let me know if there are any problems. Herby? :-) Thanks, Alistair

valueUnpreemptively breaks coverage with ZnClient
by Peter UhnÃ¡k Dec. 3, 2017

Dec. 3, 2017

After much digging as to why my tests are timing out even though running directly was always fine... I found out that TestRunner's coverageRun is using #valueUnpreemptively to run all tests. The problem is that one of the tests is retrieving something over network, and that apparently doesn't go well together. This works [ (ZnEasy get: 'http://example.com') entity contents ] value This freezes the image forever and runs a CPU core at 100% [ (ZnEasy get: 'http://example.com') entity contents ] valueUnpreemptively Is there some resolution to this? Thanks, Peter

How do you store and manage small programs?
by Andy Burnett Dec. 2, 2017

Dec. 2, 2017

I have just created a couple of small playground scripts that do some useful data wrangling. The chances are that I will reuse them from time to time, but with tweaks. Does version 6 Have some way to store them? I think I am after a sort of scripts catalogue.

Simplifying a File reference
by Prof. Andrew P. Black Dec. 2, 2017

Dec. 2, 2017

I have a file reference containing multiple occurrences of .., like this File @ /Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace How do I simplify this to show the simpler path without the .. ? There should be a method on FileReference, no? Something like #normalize ? Or maybe FileReference should do this automatically when it is created? Andrew

Newsletter content / editors wanted
by Marcus Denker Dec. 1, 2017

Dec. 1, 2017

Hi, You might know that we are sending out a monthly pharo newsletter, it contains larger âmini articlesâ (e.g. announcements) and small one-line notes for blog posts, new libraries, things like that. Here is the archive: https://us11.campaign-archive.com/home/?u=6f667565c2569234585a7be77&id=0486… <https://us11.campaign-archive.com/home/?u=6f667565c2569234585a7be77&id=0486…> Target audience are especially those who no follow the mailing list, but I think it is interesting even for us as it is easy to not see all the interesting news. If you have content: please send it to me, I collect things over a month and then we put the newletter together from that. This can be: - small (half page) articles abut *your* project! - an interesting library you found - a blog post you have written (or read) People can even take over for a complete month and do e.g. a themed newsletter focusing on one aspect or project. Marcus
