Command Line Interface using FFI

by Guillermo Polito

I've spent a few hours playing with Alien+FFI and I did want to have a Command line interface to play and use as a quick browser. Gofer it squeaksource: 'CLInterface'; package: 'ConfigurationOfCLInterface'; load. ConfigurationOfCLInterface load. To play with it write a script, for example startCLI.st, with the following: *CLInterface start* And then, from the command line CogVM -vm-display-null <image> startCLI.st What it does support? - executes smalltalk expressions - handles the errors and shows them into the stdout (so it does not explode :P) - stores variables as a workspace Since I used standard C functions (fgets and printf only) this should work on every platform from scratch (having a VM with FFI working, of course)... The problems I've ran so far: - blocking FFI blocks the vm. I've not tried yet to use threads through FFI (and I don't know if it works. Does it?). But It should be great to start a headless seaside server with a command line :/. Ok, it's a very simple thing, but it allows to execute a expression from a remote server via ssh without doing much :). Guille

Re: [Pharo-users] Enhanced Scamper or Real Browser

by StÃ©phane Ducasse

Hi john long time ago in the microsoft paul allen interval lab, jon hyland developed a browser all in squeak. Now some people enhanced scamper but I do not have the idea of its state. Let us know if you learn something.

Enhanced Scamper or Real Browser

by John Gardner

Hello Everyone, Just wondering if someone had either enhanced Scamper or developed a real web browser that compares with Firefox in browsing and rendering of web pages... don't really care about Javascript support. Please let me know.

Fwd: [Pharo-project] Pharo sprint in Brussels on Feb 4th

by Mariano Martinez Peck

---------- Forwarded message ---------- From: Andy Kellens <akellens(a)vub.ac.be> Date: Fri, Jan 27, 2012 at 11:35 AM Subject: [Pharo-project] Pharo sprint in Brussels on Feb 4th To: Pharo-project(a)lists.gforge.inria.fr Dear Pharoers, In an earlier mail Stephan Eggermont already mentioned that there will be Pharo sprint collocated with the FOSDEM conference next week. This sprint will take place on Saturday February 4th from 10h until 18h in the rooms of the Software Languages Lab of the Vrije Universiteit Brussel. More precisely: Room 10F720 (10th floor of building F) Vrije Universiteit Brussel Pleinlaan 2 1050 Brussels Due to renovations to our building, you will have to enter via the entrance between buildings F and G. As the university is normally closed on a Saturday, you might have to pass via security in order to be allowed entrance to the building (they have been notified about the sprint). If you are coming by car, please send me your license plate so that I can make sure that you are allowed to enter the campus. To get some idea of how many people to expect, could you please let us know if you are planning to attend. Kind regards, Andy -- Mariano http://marianopeck.wordpress.com

Primitive failed when compiling Vm on Windows

Hi! I've downloaded version 3.8 of ConfigurationOfCog on Pharo 1.4, and when sending #topDir: to a CogWindowsConfig instance, I get a primitive failed error: PrimitiveFailed: primitive #primCreateDirectory: in DosFileDirectory failed 25 January 2012 7:24:30 pm VM: Win32 - IX86 - 5.1 - CoInterpreter VMMaker.oscog-eem.140 uuid: 2487009c-2c13-4609-b89e-77f0e195f433 Dec 12 2011, StackToRegisterMappingCogit VMMaker.oscog-eem.139 uuid: c2849383-9768-4948-b9b2-a5c22d482b07 Dec 12 2011, r2522 http://www.squeakvm.org/svn/squeak/branches/Cog Image: Pharo1.4a [Latest update: #14296] DosFileDirectory(Object)>>primitiveFailed: Receiver: DosFileDirectory on '' Arguments and temporary variables: selector: #primCreateDirectory: Receiver's instance variables: pathName: FilePath('') DosFileDirectory(Object)>>primitiveFailed Receiver: DosFileDirectory on '' Arguments and temporary variables: Receiver's instance variables: pathName: FilePath('') DosFileDirectory(FileDirectory)>>primCreateDirectory: Receiver: DosFileDirectory on '' Arguments and temporary variables: fullPath: '\\MinGW' Receiver's instance variables: pathName: FilePath('') DosFileDirectory(FileDirectory)>>createDirectory: Receiver: DosFileDirectory on '' Arguments and temporary variables: localFileName: '\\MinGW' Receiver's instance variables: pathName: FilePath('') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '' Arguments and temporary variables: lPath: '\\MinGW' localPath: '\\MinGW' Receiver's instance variables: pathName: FilePath('') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW' Arguments and temporary variables: lPath: 'msys' localPath: 'msys' Receiver's instance variables: pathName: FilePath('\\MinGW') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW\msys' Arguments and temporary variables: lPath: '1.0' localPath: '1.0' Receiver's instance variables: pathName: FilePath('\\MinGW\msys') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW\msys\1.0' Arguments and temporary variables: lPath: 'home' localPath: 'home' Receiver's instance variables: pathName: FilePath('\\MinGW\msys\1.0') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW\msys\1.0\home' Arguments and temporary variables: lPath: 'Guille' localPath: 'Guille' Receiver's instance variables: pathName: FilePath('\\MinGW\msys\1.0\home') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW\msys\1.0\home\Guille' Arguments and temporary variables: lPath: 'cog' localPath: 'cog' Receiver's instance variables: pathName: FilePath('\\MinGW\msys\1.0\home\Guille') DosFileDirectory(FileDirectory)>>assureExistenceOfPath: Receiver: DosFileDirectory on '\\MinGW\msys\1.0\home\Guille\cog' I followed the error up to: DosFileDirectory class>>privateFullPathForURI: aURI | path | path := aURI path unescapePercents.

I've done a temporary fix like this in my image so I can continue, but maybe someone has a little more knowledge on this class: DosFileDirectory class>>privateFullPathForURI: aURI | path | path := aURI asString unescapePercents.

No idea you have the actalk library (you should be able to implement the paper of briot in one afternoon - we did this in the past as an experiment for somebody to learn smalltalk) and you could also port future from squeak but this is just the basis for On Jan 24, 2012, at 4:58 AM, vvernon wrote: > Was any progress made with this or any other Actors library? > > Thanks! > > Vaughn > > -- > View this message in context: http://forum.world.st/Actors-library-tp3619729p4322838.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >
