Re: [Pharo-users] Where did all the Comments Go?
To try and make some progress, I copied a working image from another machine.

I downloaded a new Pharo Launcher (the old one could no longer figure out which version of the VM to use), used the Launcher to create a Pharo 7.0 stable image, and started loading my packages into it from github.
My attempt to install the baseline of my code failed when some initialization code could not get the definitionComment for my parser (which is written using SmaCC). Normally, SmaCC stores oneâs whole grammar _as a method comment_ in a method called definitionComment. Oddly, this method was empty, even though the version on disk (in the file Grace-Parser.package/GraceParser.class/class/definitionComment.st) contained the comment, as I expected.
Hoping to at least complete the installation of my code, I manually copied the comment from this file into Calypso and saved the method. It looked fine, but as soon as I moved Calypso to another method, and then back again, the comment had disappeared. I experimented with adding comments to other methods: they looked fine, and I could save the method, but if I moved to another method and then back, the comment had disappeared.
Class comments have also disappeared.
I donât think that this is a Calypso problem, because the loading of code from git would not involve Calypso. Rather it is a code storage problem. I saw a File System primitive failure when I launched my new image, but ignored it; Iâm guessing that the comments disappear because they are only in the file system, whereas the code is in memory. And for some reason I canât access the sources file? The changes file ahs been created as expected.
I just tried downloading the VM manually, and running the âstableâ image that I created, and this time got a different file system primitive failure on startup: #createDirectory in MacStore.
Whatâs going on? Whatâs the right way to get a working Pharo in the New World Order?

Andrew, Are you saying all method and class comments are gone, in the whole system, or just the ones from new code that you loaded ? And is this the case only for you own code, or anything loaded extra ? Sven

Hi Andrew- If you use the scripts from https://get.pharo.org (for 32 bit) or https://get.pharo.org/64 (for 64 bit) to download a vm+image e.g. curl https://get.pharo.org/64 | bash Do you also have the disappearing comments issue? I can't imagine it would make a difference and that you'll still see the problem but it would be a ten minute test at most. FWIW I can write and read class comments in Pharo 7 just fine, but don't use and never load SmaCC. Could it be a problem with SmaCC + Pharo7? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
I gave up working on this issue back in September because I had other things to do, but never resolved it â unless you call screen-sharing to another machine that does continue to run Pharo a "solution" As far as I can see, the problem is that my Pharo VM can't find the primitives that allow it to access the file system. This means that nothing that requires file system access â including getting the sources â will work. Of course, this makes no sense, because Iceberg had just loaded my code from the file system ... but perhaps using a different mechanism? I did try your suggestion to get a more stable Pharo:
$ curl https://get.pharo.org/64 | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 237 100 237 0 0 49 0 0:00:04 0:00:04 --:--:-- 52 bash: line 1: syntax error near unexpected token `newline' bash: line 1: ` < !DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN" > ' $
Then I tried
$ curl https://get.pharo.org/64/stable | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3260 100 3260 0 0 4234 0 --:--:-- --:--:-- --:--:-- 4239 Downloading the latest 70 Image: http://files.pharo.org/get-files/70/pharo64.zip Pharo.image $
which created Pharo.changes, Pharo.image, and Pharo7.0-32bit-ccd1f64.sources in the current directory. Presumably, it also put the 64-bit VM somewhere, but I don't know where. If I just do
$ open Pharo.image
Pharo runs, and so does Iceberg, but the image that it's running is my broken Pharo launcher image, not the new one that was just downloaded, and the VM running it is a 32-bit VM, because MacOS warns me that it is out of date, and that it won't keep working for much longer. So clearly Zeroconf is not, and I have issues with broken bits of old Pharos on this particular computer, but I'm no closer to figuring out how to actually run Pharo again. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Try: $ ./pharo-ui Pharo.image Unless you did not yet download the VM. You can download both using $ curl get.pharo.org/64/70+vm | bash on macOS and Linux Sven
