Considering resignation as maintainer
by Robert Goldman 10 Jan '22

10 Jan '22

I have discovered that Stas Bokuraev is continuing to refuse to update Edi packages to modern ASDF system-naming. This would not be bad in and of itself, because these are open source systems, and they can be forked. What *is* bad is that he has publicly stated that he is doing this hoping that the resulting warnings will break people's systems and thus cause them to get angry and complain to me about ASDF checking system names. What is even worse is that the CL community tacitly accepts this as normal behavior. I would like to see the CL open source community pause and consider what constitutes a healthy community. I don't believe that someone trying to break things in order to pressure a volunteer maintainer of infrastructure is something that a healthy community should accept. If the community prefers a more rough-and-tumble approach, I can accept that, but if so it's time for the community to find an ASDF maintainer who is more in harmony with the values it (at least implicitly) espouses.

Re: Re: How to use lisp packages from libraries?
by Иван Трусков 06 Jul '21

06 Jul '21

Thanks for your explanation! I have changed lisp code to have package definition and in-package declaration, and after that everything did work (also, i per your advice used package name in symbol lookup in C code). There is one thing i would like to discuss a little bit further. >The question you need to answer is whether you want your program defer >to run-time, on the user's workstation, when to use quicklisp to > donwload and install the "str" system, and load it into your program > to get the "STR" package and its functions? Do you realize that every > month, new systems are added to quicklisp, but also SOME SYSTEMS are > REMOVED from the quicklisp distribution!? Do you want your program to > break next month because the quicklisp maintainer decided to remove > some depdency from its distribution? 1) packages changing in repository is, well, just the fact of life. In most cases hoping for the best is enough. I mean, there is no certain guarantee that digital infrastructure taken for granted will be there tomorrow? 2) what i am really curious about is: when my lisp package is compiled, let us say, monolithically - is used package "pulled into" it? In resulting object fdile, is there all the machine code corresponding to the functions from it that i have used? Maybe to other ones?

How to use lisp packages from libraries?
by Иван Трусков 05 Jul '21

05 Jul '21

I am trying to use a package function in my lisp library that will later be called from a C application. To be precise, it is shorten function from the str package. Here is my lisp library text: ;; (require :str) ;; (use-package :str) (defun echo-string (s) (coerce (format nil "Recieved input: ~10A" (shorten-string s)) 'base-string)) (defun shorten-string (s) (declare (string s)) (let ((l (length s))) (if (> l 10) (concat (shorten 7 s) (substring (- l 3) nil s)) s))) First lines are commented out because i do not know their necessity in the library. That's part of the question. However, all i get when trying to use any function from this library is a number of undecipherable errors, like this: https://pastebin.com/Sn8jgE9f Here is my C code for a minimal case: #include <stdlib.h> #include <stdio.h> #include <ecl/ecl.h> // utility functions cl_object make_cl_string(const char * pstring) { return ecl_make_constant_base_string(pstring, strlen(pstring)); } int main(int argc, const char* argv[]) { /* Initialize ECL */ ecl_set_option(ECL_OPT_TRAP_SIGSEGV, false); cl_boot(argc, argv); extern void init_lib_ASDF(cl_object); ecl_init_module(NULL, init_lib_ASDF); // is this necessary? extern void init_lib_ECL_QUICKLISP(cl_object); ecl_init_module(NULL, init_lib_ECL_QUICKLISP); cl_object ecl_module_name = make_cl_string("ecl-quicklisp"); cl_require(1, ecl_module_name); cl_object str_module_name = make_cl_string("str"); cl_require(1, str_module_name); // this code fails, not clear what use as package designator /* cl_object str_package_name = make_cl_string(":str"); */ /* cl_use_package(1, str_package_name); */ extern void init_embedded_console(cl_object); ecl_init_module(NULL, init_embedded_console); // library calls cl_object fname = make_cl_string("ECHO-STRING"); cl_object echo_func = cl_find_symbol(1, fname); assert(ECL_SYMBOLP(pstate->echo_func)); const char * line = "hello"; cl_object call_result = cl_funcall(2, echo_func, make_cl_string(line)); char * msg_str = malloc(call_result->string.fillp + 1); memcpy(msg_str, call_result->string.self, call_result->string.fillp + 1); printf("Output: %s\n", msg_str); free(msg_str); const char * line2 = "hello"; call_result = cl_funcall(2, echo_func, make_cl_string(line2)); msg_str = malloc(call_result->string.fillp + 1); memcpy(msg_str, call_result->string.self, call_result->string.fillp + 1); printf("Output: %s\n", msg_str); free(msg_str); return 0; } What should be done for me to be able to use some package (installed with quicklisp) from my ECL library? How should the initialisation be done?

ASDF 3.3.5 is released

Please consider upgrading the version you are distributing with your implementation. Note that this is strictly a bug fix release so should not cause issues in upgrading. But "should" -- software is unpredictable. Announcement email follows. Best, R

Flags for other platforms during static lib compilation?
by Joshua Armenta 29 Jun '21

29 Jun '21

Is there a flag to set another architecture type during the compilation process? For example I’m on an Intel Mac but I want to make a project build for ARM Mac (or a fat binary) to not use Rosetta 2 for that version. Or, I’m on a Mac but want to cross compile the lisp project/static library to windows. Trying to integrate some code into a CI platform. Thx!
