Re: [Pharo-users] remove unused variables

by Johan Fabry

This was changed somewhere in November by Marcus and Miguel, and it was intentional, as part of the work on annotations on the AST that enabled breakpoints.

Re: [Pharo-users] meaning of #workingDirectory in in-memory file system

by Damien Pollet

In a unix system, there is only one filesystem. Meaning: if you have several disks or partitions, either they are mounted in The Unique Filesystem, or they are not mounted and are just a blob of some gigabytes. The working directory is a per-process property, not per-filesystem. (except that windows has a current directory per drive letter, IIRCâ¦) In the case of memory filesystems, since they are useful for temporary stuff or for testing things on files without side effects on disk, you could see them as a sandbox where any starting point is acceptable. Or maybe we need a concept of a use session for a filesystem, and then the working directory is a property initialized when the use session is instantiated.

remove unused variables

by Peter UhnÃ¡k

The editor used to inform when there was an unused local variable and offered to remove it. Is it possible to get this behavior back, or is it a feature regression with the "new" (this changed some time ago) editor? Thanks, Peter

meaning of #workingDirectory in in-memory file system

by Peter UhnÃ¡k

fs := FileSystem memory. fs workingDirectory "memory:///". What is the conceptual meaning of #workingDirectory here? Shouldn't it just throw an error for memory FileStore as it makes no sense? I.e. I didn't launch any image from memory. Peter

Re: [Pharo-users] Hello World (found a RoelTyper Bug)

by Diego Orellana

Pablo, can you give us some usage examples? First I would like to get the type inference data programmatically in order to compare the type data with other tools. And also, I would like to open the IBBrowser. Here's what I've tried so far: For getting argument types: (((J2Inferer default inferClass: RTView; typeInfoFor: RTView) methods at: #setCanvas:) parameters at: 1) subtypes But subtypes is a set of J2ParameterRelationship objects which I don't know how to get the types from them. And I've managed to open the IBBrowser like this: IBBrowser openOn: (RPackage organizer packageNamed: 'Roassal2') using: (J2Inferer default) the browser at first opens fine and shows all the packages and instance variables but it doesn't show any methods and when I click an instance variable I get an error. What am I doing wrong? I'd be very thankful if you helped us :D Cheers, Diego. 2016-04-21 10:56 GMT-03:00 Alexandre Bergel <alexandre.bergel(a)me.com>: > How to open a IBBrowser by the way? > > Cheers, > Alexandre > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > > On Apr 21, 2016, at 10:06 AM, tesonep(a)gmail.com wrote: > > Hi Diego, the most updated version is published in GitHub. > > https://github.com/tesonep/j2Inferer > > In that place there is also some documentation. > > Cheers, > Pablo > > On Thu, Apr 21, 2016 at 7:29 AM, Diego Orellana <dorellang(a)gmail.com> > wrote: > >> Hi Pablo, >> >> Well, I tried to load the packages from your repositories, but I >> couldn't.

Hi Pablo, We are diving into the mysteries of BaselineOf. After having cloned the github repo and loaded manually the baseline. We tried: BaselineOfJ2Inferer project version load But we get a could not resolve: J2Inferer-Implementors. No idea whether your Baseline is oddly defined or Metacello/Baseline/Filetree are buggy :-( How can we load your application?
