jcowan: as an example of this, check how ASDF displays the dots while compiling systems.

Hello, can I use my existing GitLab account to sign into https://gitlab.common-lisp.net/, or do I need to make a Common-Lisp GitLab account?
23:58:04
White_Flame
so no, it wouldn't have anything to do with the accounts registered on the one that gitlab.com is running

doesn't really say much about Gitlab's confidence in gitlab.com that you can sign in with other sites (even Github!) but not with Gitlab

My question was unclear: https://gitlab.common-lisp.net/users/sign_in does not accept my existing Gitlab credentials.

https://common-lisp.net/project-intro has an email for a CL admin, but that email looked like it was intended for joining a project; I just want to report an issue.

HM0880: in case of doubt there's a #common-lisp.net channel where you can ask the admins themselves

reading the book Structure and Interpretation of Computer Programs says that the language it convers is Scheme and not Lisp, is this normal?

I've noticed a glitch in the matrix, it may be that they do something to the r eality ,)

Lisp is often used in a sense "languages that descend from LISP 1.5", in this sense scheme does not qualify. that said scheme is considered a lisp dialect regardless by many (if not most) people

there is this weird split between people who believe lisp means a family of lisp languages and that lisp means CL and CL-like languages
8:52:45
pjb
rendar: that's correct. scheme is more pedagogical a programming language than Common Lisp. That's why it's often used in books and lectures.
8:53:13
pjb
rendar: but as a programmer you must be used to switching to different languages, and even to write programs that work as-is in several languages!!!
8:54:37
jackdaniel
sicp is a book about writing programs, scheme is used as a language to illustrate various concepts
8:54:51
pjb
rendar: see for example: https://github.com/informatimago/happy/blob/master/happy.source or Have a look at (intersection common-lisp emacs-lisp scheme) http://www.informatimago.com/develop/lisp/com/informatimago/small-cl-pgms/intersection-r5rs-common-lisp-emacs-lisp/
8:55:11
pjb
rendar: it's a common misconception. sicp is not a book about lisp or scheme. It's a book about programming!
8:55:34
pjb
rendar: people have been doing the exercises in sicp in all kinds of languages, from CL to C++.

can we say that a symbol is a string, and that the environment is an hash table mapping that string, to that internal structure?
9:06:24
rendar
well, that every Lisp have an internal representation of a symbol is a no brainer thing, its obvious, what i want to get is that internal structure is the 'value' whose symbol name (the 'key') points to, with an hash table
9:07:49
pjb
rendar: but quite often the name doesn't matter at all. You can (make-symbol "") #| --> #:|| |# and this can be useful (eg. in macros).
9:08:03
jackdaniel
yes, the symbol name is a string, and you may use hash tables to implement most mappings if you assume that there are no packages (i.e symbol names are unique)
9:08:22
pjb
rendar: we often use gensym in macros, to get different symbol names, but this is only useful when you debug the macro, to not be confused by different symbols having the same name.
9:09:19
pjb
rendar: note that usually you don't want the value stored in the symbol whose name is given.
9:10:31
pjb
rendar: basically, the system could throw away all the symbol names at runtime, and keep working.
9:10:55
pjb
(unless, of course, you do some reading at run-time, which often occurs of course; but it's independent).
