How can I measure GC pause length? in c/lisp
[–] Decweb@alien.top 1 points 10 months ago

You might read docs about some CL based games, like Khandria, where they talk about dealing with gc. (TL;DR, not a major problem). Sorry, I don't have a link for you.

Note that you can also work to writing less consing-intensive code too (more preallocated data structures, efficient use of fixnums, the stack, and lisp-specific extensions that allow you to do more tricks with the stack or malloc()'d memory.

SBCL has gc hooks you might also use too, though I don't think it'll give you the duration of the just-finished gc.

Variable: *after-gc-hooks* [sb-ext]

You might be able to just increment a counter, and call (room) each time, and at least log the data (assocaited with the counter) for subsequent analysis.

does lisp have a future? (noob (don't take too seriously)) in c/lisp

Lispers know their time is too valuable not to use lisp.

I may have found a solution to my desire for C-c C-z in the slime repl (default slime-nop) to return you to the buffer that sent you to the repl via slime-switch-to-output-buffer (also C-c C-z), with regard to a post/request I made a year ago:

https://www.reddit.com/r/Common_Lisp/comments/xa7imh/seeking_reverse_of_slimeswitchtooutputbuffer/?utm_source=share&utm_medium=web2x&context=3

Basically calling a function which does (switch-to-buffer (slime-recently-visited-buffer 'lisp-mode)) works, or at least does something interesting by approximation.

I'm not much of an emacs coder though and I'm at a loss though as to how to bind my new function calling the above switch-to-buffer to C-c C-z only in the slime repl buffer. Any tips?

That's the closest approximation (so far) of what I was looking for, though unfortunately I'm a slime user and haven't yet tried sly.

I'm actually surprised there isn't speedbar for CL definitions already in slime, somehow I figured it was an obvious thing I was missing, since you see that sort of thing all the time in IDE's.

Nice tips for future use though not quite what I'm looking for (though the prefix tip is one I'll have to remember).

Are the sly presentations in a speedbar or special buffer of some kind, or just listed in the REPL?

When editing common lisp with slime and emacs, I'd like a speedbar listing, alternately, top level definitions in the file I'm editing, and top level definitions in the package I'm looking at (which may be a superset of definitions in the file). Preferably sorted by type of definition (function, macro, constant, etc) and/or alphabetically.

Is there some emacs tooling for this? I haven't found it.
