Trying to use mu search in gnus and failing in c/emacs
[–] brittAnderson@alien.top 1 points 1 year ago (1 children)

Thanks. I was doing that for a while, but when my University moved to office365 and I had to add davmail to the mix my refreshing for new mail got very slow as it insisted on looking at all the folders. I was hoping to just use nnmaildir and drop dovecot from the mix, but maybe I will find it easier to fix dovecot than get mu working.

Trying to use mu search in gnus and failing (alien.top)
 

Trying to use mu for searching in gnus and never getting any results. No error messages, just empty search. mu find on the command line works fine and returns what is expected (and does in mu4e as well), but this does not give me anything in Gnus. Any suggestions? ...

(setq gnus-secondary-select-methods
  '((nnmaildir "mail"
	   (directory "/home/britt/.local/share/mail")
	   (gnus-search-engine gnus-search-mu))))
Help me understand how to modify a running function. in c/lisp

Thank you for you library. It would be great to have a tutorial about how to get started that includes some of this. I know you are busy working on the library, and that is what I hope you spend your time, but I will keep good notes on my experience and maybe I can contribute some sort of tutorial blog post or something. Cheers,

Thank you very much. The following is for any future visitor who ends up here with a similar question.

One of my challenges with this example code is that the make-ball function was in a let*. The original example authors were using a move-ball function in their main game loop. So, inspired by your suggestion I wrote a color-ball function with a setf for the color slot of the shape object. Then I wrote an upd-ball function that just called move-ball and then color-ball internally using the ball object created in the let. Then, it all works great. If I adjust the "move-ball" function and recompile the ball speed changes, and if I adjust the "color-ball" function the color changes.

Since you were kind of enough to respond, do you have a recommendation among the raylib wrappers (or the sdl or allegro wrappers or others, including yours) that you recommend as being particularly beginner friendly and also encouraging of good habits for someone learning some simple graphics manipulation with CL?

Help me understand how to modify a running function. (alien.top)
 

The idea that one can change and modify code while it is running sounds great, but I have never really gotten to the point that I understand practically how to do it in a non-trivial circumstance. As a concrete example where I think I should be able to do it, but I can't, is when running one of the examples from the claylib system. I am using slime/emacs and I open claylib/examples/shapes/bouncing-ball.lisp. In slime I use (in-package :claylib/examples/bouncing-ball) and then (main) and I have the bouncing ball demo working fine. What I have tried to do is to change the color of ball from its current +maroon+ to some other color. I have tried editing that part of the function definition in bouncing-ball.lisp and recompiling, but nothing changes. If I kill the running example, recompile the bouncing-ball.lisp and then re-run main I see the new color, so I know that I am specifying a color correctly. Would someone tell me the steps to change the ball color while it is bouncing around to help me get started on this "live" coding method? Of if they think one of the other raylib wrappers would be better for this I can change. I am just using this as a learning tool to give me some visual feedback as I make changes. Thanks.
