Thank you for the responses. I'll try both of them, but in the meantime I found another problem because of my lack of experience. I'm trying to define in the baseline a dependency with another project, in particular the Stamp project by Sven Van Caekenberghe [1] in Smalltalkhub in the following way: baseline01: spec <version: '0.1-baseline'> spec for: #common do: [ spec blessing: #baseline. spec repository: 'filetree://full-filesystempath-to-your-pharo-subdirectory '. spec project: 'Stamp-Core' with: [ spec repository: 'http://smalltalkhub.com/mc/SvenVanCaekenberghe/Stamp/main'; loads: 'Stamp'; version: #stable ]. spec package: 'MyStompMessaging' with: [ spec requires: #('Stamp-Core') ] ] When I evaluate the following in a Workspace: (ConfigurationOfMyPackage project version: '0.1') load. I get the followin error: MessageNotUnderstood: receiver of "ensureLoadUsing:" is nil In the debugger I see that MetacelloMCProjectSpec>>projectPackage is nil. In an old thread I found that Dale Henrichs suggests to try this: MetacelloProjectRegistration resetRegistry; primeRegistryFromImage But in my case It does not solve the problem.

Re: [Pharo-users] Opentalk or remoting libraries

by Alain Rastoul

Hi, CORBA main focus is about interoperability between systems, languages (don't know about opentalk). If you want smalltalk only remote execution, you can very easily do your own on Pharo with Zinc http components and Fuel serializer: a small server that reads smalltalk blocks, evaluates them and return the result (see below an example of server and client). I don't know if Zinc and Fuel run on Squeak, but I guess if not, they are equivalents ones or you could do the same. Beware that Fuel builds a graph of the objects touched by the object it serializes (the block) and serialize them along the way, that may be a problem if you have references to other big objects of your image.

Re: [Pharo-users] Error when compiling a string with a quote

by Sven Van Caekenberghe

I was too quick to respond, the #storeString conversion is OK: (#( $f $o $o $' $b $a $r) as: String) storeString collect: [ :each | each ] as: Array. => #($' $f $o $o $' $' $b $a $r $') The contract of #storeString is, given a String (well any object), what should it look like when written as a literal constant in source code. That is precisely what you want, no ? but you have to drop adding your own quotes, like stream << 'description' << Character cr << Character tab << $^ << dialog description string storeString. or even (as #printOn: is the same as #storeOn: for String) stream << 'description' << Character cr << Character tab << $^ print: dialog description string. And I would turn this into a cascade, but that is more coding style. stream << 'description'; cr; tab; nextPut: $^; print: dialog description string. > On 13 Nov 2014, at 18:26, Hilaire <hilaire(a)drgeo.eu> wrote: > > Le 13/11/2014 18:05, Sven Van Caekenberghe a Ã©crit : >> I think you need to send #storeString to the result of 'dialog description string'.

Re: [Pharo-users] Metacello configuration based on subdirectory of Git repo

by Dale Henrichs

Rafael, To get to a git repository use a filetree repository and point to a local clone of the repo. I've editted your baseline accordingly: baseline01: spec <version: '0.1-baseline'> spec for: #common do: [ spec blessing: #baseline. spec repository: 'filetree://full-filesystempath-to-your-pharo-subdirectory'. spec package: 'MyPackage'. . . . ] If you hafve a project on github or bitbucket you can reference the repository directly (readonly) with the following url: github://github_username/github_projectname:branch_SHA_tag/path_to_subdirctory for bitbucket, you just use bitbucket: instead.

Yep, I realized it is not double quoted. I used this message copyWithRegex: '''' matchesReplacedWith: '''''' However both #storeString or #printString messages can't do the job. 'n''a pas l''e' storeString -> '''n''''a pas l''''e''' ('n''a pas l''e'copyWithRegex: '''' matchesReplacedWith: '''''') -> 'n''''a pas l''''e' #storeString seems to mess up with the quote, adding superfluous one.

Metacello configuration based on subdirectory of Git repo

by Rafael Luque

Hi all, I'm starting with Pharo and playing with the ways to integrate it with Git. I've read the "Git and Pharo" chapter on "Enterprise Pharo" book by Thierry Goubier and loaded the GitFileTree package. I'm working on a project with several microservices, one of them will be based on Pharo and the other ones in other technologies. The project repository is based in our own Git server and each microservice maps with one subdirectory in the repo. My question is if it is possible to define a Metacello configuration to load my packages from an specific subdirectory of a Git repository. I have tried with the following baseline method, but it fails because does not understand repoPath: baseline01: spec <version: '0.1-baseline'> spec for: #common do: [ spec blessing: #baseline. spec repository: 'git@my-git-server:my-project'. spec repoPath: 'my-pharo-subdirectory'. spec package: 'MyPackage'. . . . ] Thank you in advance.

Error when compiling a string with a quote

by Hilaire

Hello, I get an error (see screenshot) when I compile at runtime a method where a quote is found in its body. I expect this compiled method: description ^ 'n''a pas sa force' The user inputs part of this method as: n'a pas sa force In its string representation, it is displayed as: n''a pas sa force with the quote correctly escaped. But compiling fail. I use this code to compile at runtime: stream := WriteStream on: String new. stream << 'description' << Character cr << Character tab << $^ <<$' << dialog description string << $'. scriptClass class compile: stream contents classified: 'public'. -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

Keyboard support in Linux is suboptimal. I should do a pass on that one of these days. It is in the pharo-vm/platforms/unix/vm-display-X11/sqUnixX11.c file, lines 2001-2364 and a bit after. (+ x2sqmodifiers function). https://github.com/pharo-project/pharo-vm/blob/master/platforms/unix/vm-dis… There is a DEBUG_KEYBOARD_EVENTS define one can set to see what's going on. My keyboard is french belgian. There are also issues in CentOS that have nothing to do with Pharo as things are also going bad in native apps.
