Hello Calva friends: I made a small fix so that the hover definition will show for values preceded by @ and '. I'm pretty sure this will not affect other things negatively, but some testing by others would be nice before merging. The VSIX is here https://1930-125431277-gh.circle-artifacts.com/0/tmp/artifacts/calva-2.0.58-fix-find-definition-for-derefed-value-c8a3c398.vsix and the PR is here https://github.com/BetterThanTomorrow/calva/pull/449

👋 In Calva, is it possible to stop the current evaluation. For example, if one evaluates (Thread/sleep 1000000), is there a way to stop it, without restarting Calva?

shadow-cljs lets you start a background server:

$ yarn shadow-cljs start
yarn run v1.17.3
$ D:\work\learn-re-frame-course-files\cheffy\node_modules\.bin\shadow-cljs start
shadow-cljs - config: D:\work\learn-re-frame-course-files\cheffy\shadow-cljs.edn  cli version: 2.8.69  node: v10.16.0
shadow-cljs - server starting ..................................... ready!
Done in 10.14s.

this is useful for when you end up having several invocations of shadow-cljs

trying to jack in when there's already a shadow-cljs server makes the jack-in process hang

the terminal window will say this:

shadow-cljs - config: d:\work\learn-re-frame-course-files\cheffy\shadow-cljs.edn  cli version: 2.8.69  node: v10.16.0
shadow-cljs - connected to server
shadow-cljs - watching build :app
[:app] Configuring build.
[:app] Compiling ...
[:app] Build completed. (691 files, 690 compiled, 0 warnings, 46.46s)

and the repl will never connect

I think this is because Calva is waiting for the repl port to be printed

if I stop the server via yarn shadow-cljs stop and jack in again, it will work

I imagine that it's because the terminal that Calva uses will have more information

my question is: could I configure calva in some way that jack in will work even with the background server?

maybe using the "calva.replConnectSequences" config item?

I am not sure I follow correctly. But let’s start with this: > this is useful for when you end up having several invocations of shadow-cljs When do you end ip having several invocations?

Calva used to be a bit unhelpful with what parameters this or that function accepts. This changed a while ago, when @c.fehse added the parameter info to the the function hovers. In the last few versions of Calva Christian continued to improve this, by adding signature help while typing. It is a bit crude in its current form, but that is also about to change, because now we have worked together on it a bit and this is what it looks like in the PR branch. What’s new is that we show the function name, the relevant signature of the function and which argument you are currently typing. These things currently work only for non-special forms, but anyway, those are plenty. Can we get some help testing this? Here’s the VSIX: https://github.com/BetterThanTomorrow/calva/pull/450 And here is some info about Calva VSIX packages, and how to install them, and how to stop using them: https://github.com/BetterThanTomorrow/calva/wiki/Testing-VSIX-Packages

OK, so you can actually find the VSIX from the PR link I pasted, but here’s a direct link, for your convenience 😃 : https://1991-125431277-gh.circle-artifacts.com/0/tmp/artifacts/calva-2.0.58-wip-sinature-handler-use-paredit-58dbd0ff.vsix
