BTW, I had a quick look at Analyze Plugin Startup Performance and Cursive takes the most time to initialize: 

❯ pbpaste|awk '{cnt=$NF; $NF=""; print cnt, $0}'       
1896 Cursive 
1710 Grazie 
677 Database Tools and SQL 
447 JavaScript and TypeScript 
...
I'm wondering, if there would be any low-hanging fruits, which could lower this initialization time. Have you looked into this @cfleming yet?

(I just copy-pasted from this table from the IntelliJ UI and that little awk script at the beginning moves the last time column to be the 1st, so it's more readable as plain-text.)

im also curious, how would u measure this startup performance. would u use the async-profiler or yourkit? it would be exciting to see a few notes / screenshots about how do u go about investigating something like this, even if u can't improve the performance. just a few sentences would already be inspiring; i wouldn't expect a technology deep-dive.

Here is an example from our project, where I was looking into our usage of the https://github.com/oliyh/martian library. Under the hood we happen to traverse the whole HTTP request payload 4 times with clojure.walk, which can take seconds, when the payload is tens of thousands of Google Sheets spreadsheet cells.

onetom05:09:28

more precisely, 3 times with clojure.walk and 1 time with clojure.data.json

I just checked the plugin startup times in the release version (`2022.2.2`) of intellij and those are much better, so probably it doesn't worth worrying about the startup time:

unless those startup times will be the new norm in intellij 2022.3...

cfleming05:09:17

Cursive takes the most time to initialise, mostly because it uses Clojure - Clojure’s startup time is a well-documented problem. I have a plan to defer actually loading Clojure until something requiring Cursive is performed, so that e.g. opening a non-Clojure project should not cause that to happen. It’s a long-term, ongoing project though.

tlonist08:09:32

how can I apply vertical align for let bindings where there is a destructuring? 

(let [{:keys [id]} users ; this line cannot be vertically aligned
       a [1 2 3]
       b {:a :b :c :d}] ...)

onetom08:09:42

indeed the Align let-binding values suggests that the destructuring form would be aligned too, but i can imagine it being an exception from the rule, because such destructuring forms would push other, simpler binding so far to the right, that it would become hard to see which symbol is bound to which value.

tlonist09:09:19

so I'd like to know if there is any forcible way for cursive users to do this. Do you have any idea?

cfleming05:09:58

There isn’t at the moment, no. Destructuring elements are excepted from the rule, because they tend to be very long. But they’re not always, as in your case. This has been discussed before, I’ll see if I can dig up the discussion.

Dustin Getz14:09:28

Is the Cursive extension "clojure-extras" considered standard at this point? I didn't even know about it

imre14:09:27

completely independently developed afaik, see #clj-extras-plugin
