[Pharo-project] !| || and !|! as binary methods?
by Ralph Boland April 2, 2010

April 2, 2010

A few days ago I tried to define !| || and !|! as binary methods in Squeak. Today I tried the same with Pharo. They all fail because the parser interprets the '|' character (the second '|' character in the case of ||) as the beginning of the declaration of local variables. Is this a parsing error or the way Squeak/Pharo is intended to be defined? Now you might think !| and !|! are pretty weird (which doesn't invalidate my question) but I think || is pretty natural as a binary method! Regards, Ralph Boland -- Had a wife and kids in Florida, Jack (Nicklaus) Went out for a "ride" but I couldn't get back As a ten timer being hunted down OR When the wife found out who I was knowing (biblically speaking) I hit a hydrant and I just kept going (till I hit a tree). ...

[Pharo-project] dlopen: I'm stumped
by Schwab,Wilhelm K April 2, 2010

April 2, 2010

Hello all, Attached is my attempt at calling dlopen() from Pharo, and it is not going well. The C code below works as expected, so the problem has to be either in my code or something in Pharo or the VM itself. I am fairly certain that loading the attached is safe, but DynamicLinkingLibrary getProcAddress:'cos' from:'libm.so'. crashes the vm in my experience. Any ideas? Bill /* http://www.unix.com/man-page/All/3/dlopen/ Build as: gcc -rdynamic -o fubar fubar.c -ldl */ #include <stdio.h> #include <stdlib.h> #include <dlfcn.h> int main(int argc, char **argv) { void *handle; double (*cosine)(double); char *error; handle = dlopen("libm.so", RTLD_LAZY); if (!handle) { fprintf(stderr, "%s\n", dlerror()); exit(EXIT_FAILURE); } dlerror(); /* Clear any existing error */ /* Writing: cosine = (double (*)(double)) dlsym(handle, "cos"); would seem more natural, but the C99 standard leaves casting from "void *" to a function pointer undefined. The assignment used below is the POSIX.1-2003 (Technical Corrigendum 1) workaround; see the Rationale for the POSIX specification of dlsym(). */ *(void **) (&cosine) = dlsym(handle, "cos"); if ((error = dlerror()) != NULL) { fprintf(stderr, "%s\n", error); exit(EXIT_FAILURE); } printf("%f\n", (*cosine)(2.0)); dlclose(handle); exit(EXIT_SUCCESS); }

[Pharo-project] How to measure VM changes from the image side
by Mariano Martinez Peck April 2, 2010

April 2, 2010

Hi folks. I am playing with some important parts of the VM and I would like to measure the impact of this changes. As an example, I am changing the Interpreter >> normalSend which is the code that represents the send of a message (at least that's what I understood). So, you can imagine that this will have an impact ;) So...what I would like to know if is someone has ideas of how can I measure this impact. I though some benchmarks that can be run before and after this change. In Java I know that there are some libraries or suites of benchmarks already written for this kind of purpose or similar. Is there something in Smalltalk ? Do you have some ideas for this ? It would be cool not do depend on network traffic or things like that. It would be cool also if I can do it directly from code so that it is repeatable. Maybe something that requires a lot of process, time, and involve a lot of objects...ideas? I though running all Pharo tests, or test coverage, ScriptLoader cleanUpForRelease, or cleanUpForProduction, run Lints Thanks in advance. Mariano

[Pharo-project] Registering a tool in the world menu
by HernÃ¡n Morales Durand April 1, 2010

April 1, 2010

Hi list, I'm using PharoCore 1.1 #11301. Now I want to adapt some tools to use the new menu registration mechanism. When I evaluate: menuCommandOn: aBuilder <worldMenu> (aBuilder item: #'Dependency Browser') parent: #Tools; action:[self open]; icon: UITheme current windowMenuForm. the world menu is modified including only the Dependency Browser item and all remaining items were removed. Did I miss something? Cheers, HernÃ¡n

[Pharo-project] CompiledMethod asString is a text

Hi, I just bumped into this. Probably this is intended somehow, but it does seem weird enough to ask â¦ (Object >> #hash) asString class returns 'Text'. Cheers, Niko -- http://scg.unibe.ch/staff/Schwarz twitter.com/nes1983 Tel: +41 076 235 8683

Bert, What do you mean by "declare the mode parameter" - did I not do that via the argument named int? Bill
