That most probably means there are no files in the directory. If you create one then you will see.

Hi Norbert, I tried this in a 6.1 image but I only get a normal inspector. What do I miss?

I've been discussing with Dale on the MetaC list [1] a problem I've been having with git dependencies. On my development machine, there are already local clones for all the projects I commonly work with. This makes it relatively easy to put filetree:// urls for dependency baseline repos. I don't use github:// style URLs because a) many of the repos are private and accessed via SSH keys, which MetaC did not seem to honor, and b) many are hosted on bitbucket and gitlab which at the time did not seem to be well supported by MetaC. However, after setting up CI on Gitlab for some projects, I quickly ran into the problem that the local clones of the dependencies did not already exist. A workaround was to manually clone them first, but this is tedious and fragile. I imagined maybe using gitlab:// URLs which would always fail (because they are private repos), which I could then wrap in an error handler that used e.g. OSP to clone and retry. Does anyone have a good solution for this? 1. http://forum.world.st/Bitbucket-Private-Repos-Redux-td4966412.html#a4995200 ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

In Pharo 7, I sometimes â but not always â get crashes when I switch from the built-in display on my laptop to a large desktop monitor. Going from the large monitor to the laptop screen always seems to work flawlessly, and going the other way sometimes works. So this is the opposite from your issue. The crash happens before I get to see anything at all on the screen, so it may also be a different issue. But changing resolution is certainly problematic. Andrew

Problem loading image after changing resolution from 4Kto HD

by Ted F.A. van Gaalen

Apart from my OSX MacMini, (which has other problems,still, as i wrote about earlier) I also use a PC Windows 10 system mainly for games and doing other awful complicated things like filling out German Tax forms... There is an error depending on resolution. While my PC, Windows 10, is connected to a 4K screen: [ -downloaded Pharo 6.1 from https://pharo.org/web/download -started Pharo with the downloaded vanilla image. -fonts too small to be comfortable readable so changed all to a larger font size (in the image, Appearance) -found the font edges to be a bit blurry on a 4K screen, therefore used this https://imgur.com/7G1sEtz Which lets -as far as i can tell- let the app take care of its dpi scaling. now everything was ok. Font edges where now sharp exactly what I want. -saved the image, thereby overwriting the vanilla image, not using "save as" (this because I want may base image always to contain Seaside and Postgress DB (not yet done here) , mainly because I'd like to make Smalltalk stand-alone apps in a three layer system that is DB<=>Pharo<=>Browser (a web browser is a super nice user interface)) so user-interaction is exclusively over (local)host] later at night, I like to be in gaming (like Eve Online) so the ritual is to disconnect my 4K 3840 x 2160 monitor and then reconnect my PC via HDMI 1920 x 1080 to my TV. This works flawlessly. Windows automagically changes resolution to 1920 x 1080 and even reorders all my desktop icons. Then later, after being a bit bored with gaming, thought of Pharo again, and attempted to reload it, being still in 1920 x 1080 resolution on the TV. then this Pharo window appears: [image: Inline image 1] I then tried to close this System Browser but this didn't work as it emits many windows with errors. Impossible to continue, thus I then closed Pharo *without saving the image*. Later, the next day, when restarting Pharo again in 4K resolution, everything works normally. Could it be that some logic within Pharo does not handle resolution changes correctly? You could try to reproduce this error, using the same procedure as described above.

There should be a method on FileReference, no? Something like #normalize ? Or maybe FileReference should do this automatically when it is created? On Pharo 6 use "asAbsolute" on a FileReference, like this: '/Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace' asFileReference asAbsolute "File @ /Users/black/Development/mg/gracelang/albums_junk.grace" Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch

The answer will depend on which version of Pharo you are using, but for Pharo7: '/Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace' asFileReference canonicalize "File @ /Users/black/Development/mg/gracelang/albums_junk.grace" The reason the '..' segments are left in is because while the result is probably what you are looking for, if the original reference contains symbolic links you may end up with a different result to what the file system will return.

Simplifying a File reference

by Prof. Andrew P. Black

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
