Nope I haven't actually had any of those problems (fortunately)

I haven't opened much more than Clojure, .csv and text tho

Markdown too I guess

It was slower when reloading .spacemacs tho and it threw the error

On the off chance someone has insight into this one: My remaining problem (after reinstalling basically everything) is that when I save a cljs file, emacs freezes completely for a while (say, 5-180 seconds) with maxed out CPU (on one core). Anyone encountered this lately?

all of the latest comments in this channel are making me rue updating my spacemacs... 😄

is it just cljs files

no other files?

is cider running?

are you running a special repl in cider (figwheel or just like lein/boot default repl)

Yeah, so far seems like just cljs. I should try a couple of other clj/cljc files to be certain, though. If cider is not running, it behaves just fine, no freezing. If cider is running, it consistently freezes.

I'm using a figwheel-aware REPL:

(setq cider-cljs-lein-repl
        "(do (require 'figwheel-sidecar.repl-api)
              (figwheel-sidecar.repl-api/start-figwheel! \"login\" \"imageviewer\" \"harmonium\")
              (figwheel-sidecar.repl-api/cljs-repl))")

hmm, when I was using lein that was basically what I had too

do you have anything in your before save hook

(like cleaning whitespace/formatting)

I do clear trailing whitespace, I think that's it. Currently frozen, but once it unfreezes I'll go verify whether I'm doing anything else.

Yeah, just (add-hook 'before-save-hook 'delete-trailing-whitespace)

(which I've had active for at least a year)

Next I'm going to try eliminating my .spacemacs entirely (I've already got a pretty old version checked out, from well before all this started).

Aha! Fresh .spacemacs seems to have eliminated it. So now hopefully it's just a matter of bisecting what's in my .spacemacs.

Which'll take ages, but I'm just glad there's a direction to go for a solution.

It's aggressive-friggin-indent-mode. I should have tried that sooner -- I had some bad slowdown problems with it before, but they had been resolved for a while. I really love the behavior, but not at the cost of freezing emacs for extended periods of time.

oh son of a bitch

I disabled aggressive-indent-mode a long time ago because it was so slow

that's really annoying

at least you figured it out

Yeah, I'm very glad to have finally figured it out, this set of issues cost me pretty much a full day of work. The relief slightly outweighs the frustration 😉

Wow, glad you got to the bottom of it @eggsyntax! And lame about the lost work. 😥

Oh well... far outweighed by the time that spac/emacs has saved me overall 🙂

That's fair. 👍 Plus, I'm guessing you learned some things about lower-level happenings of [spac]emacs.

I am working with some .csv files that can generate a lot of output

it seems like I’ve been frequently running into emacs crashing when I run one of these large functions and I don’t know why

anyone have problems with spacemacs crashing?

Things do get fairly bogged down for me when I have too much data in a buffer. vim scales way better that way.

When you say "crashing", does it just instantly crash, or does it get really slow/unresponsive for a while first?

the screen goes gray and everything stops responding

also is there a way to clear the repl so that I don’t have these massive swaths of screen being blasted by text?

You mean just clear what's on the screen? I use Cmd-k.

okay! thanks!

cider-repl-clear-buffer

also any advice when the REPL hangs? It seems like it’s not really doing anything and then the results of the last function call suddenly popup

I agree with @jeff.terrell, btw, if I have to deal with a really huge file, I usually do it in vim.

Try keyboard-quit (ctrl-g) or cider-interrupt (ctrl-c ctrl-c).

And don't turn aggressive-indent-mode on 😆

kk

It’s not massively huge, It’s probably only like 200 lines of .csv BUT it generates a lot of output from turning the csv into a series of maps

Ah, right, gotcha. Not sure, then. One option might be to just spit it to a file instead of printing or returning it in the REPL.

that’s a good idea

I just killed the buffer and reloaded cider and things seem to be going well

also , s c will clear the buffer in spacemacs

Totally. Same command, different key binding.

spacemacs has crashed twice on me today…. when I return to my main buffer from the repl and type SPC SPC it locks up….any idea why?
