good morning!

Morning!

Good Morning!

Morning and hello 👋:skin-tone-3: @hequ

Good morning! 🙂

Morning! I forgot a merge marker in an EDN file and it parsed correctly as a key value pair:

>>>>>>> origin/master

Yep!

I once spent ages tracking a rogue ' in an edn file which was parsed as it's own symbol

user=> (clojure.edn/read-string "{:foo '(bar)}")
Execution error at user/eval3 (REPL:1).
Map literal must contain an even number of forms

How much time do software engineers spend just looking at single character mistakes on a daily basis (cumulative )

Even more confusing was when "{:foo '}" worked. Whole can of nope right there.

that is very weird indeed.

belated morning

Anyone here with AWS RDS experience? I am stuck on creating a proxy.

Morning

morning

@thomas what kind of proxy?

a Database proxy.

they strongly suggest you use one.

Amazon do?

Really?

but when I try to create a Proxy I can't choose a DB to associate it with.

yes, they do. Part of the RDS service.

https://aws.amazon.com/rds/proxy/ ah

I don't think that applies to java too much, as we most of that baked into client libraries.

we are planning on using Lambda's

Ah, makes sense then

I wonder if that actually works. Is opening a real db connection that much more expensive than this fake one? I always assumed tcp handshakes were the delay.

the idea is that the proxy holds all the DB connections

Single character problems. Try putting a ~ on a new line at the end of a file when you’re a vi user.

I still have no idea why tildas are still a thing in vi .. anyone?

@thomas sure. But is that faster than holding them locally and establishing a new connection to the proxy repeatedly?

@raymcdermott huh you’re unable to type a tilde in vim?

@synthomat it’s the visual end-of-file marker.

One line of text
~
~
~

The tildes are vis way of showing it’s nothing here.

i know, i know – didn’t get the question though 😅

hm I’m wondering why ring has a session-wrapper that relies on storing the session key in cookies but doesn’t provide anything where the user can implement a custom “key-function”

Ray is just trolling us

If you :set number it doesn't work anyway :)

Cypher sucks. Long live gremlins. I'm too lazy to dig in, but I really hope graph query language doesn't repeat the sql mistake and make string mashing the building tool. I'm now annoyed I have to do that with cypher.

Wow, not trolling

I know it’s the end of file marker but my point is that can easily be confused for a legal character in most programming languages. The fact that you can countermeasure it doesn’t make it good

These days the editor could easily choose a more evident set of characters. I’m assuming that Unicode support is in there by now

you can change it to a different character, for example π

(nur sure if pi is better than a tilde, though)

Just saying it’s a bad default for 2020

hehe

Should be ❇️❇️❇️❇️❇️

For example

not possible, tried it out 😞

I guess because emojis have more than one character

I should continue with my work rather than trying to change that character 😄

Yeah it’s yet another sharp edge

E474: Invalid argument: fillchars=eob:ray :( boo

I used vi for decades and it’s still my fave in many contexts but just saying that there are problems

set fillchars=eob:\ does the trick anyway

Having a patch / fix really isn’t the answer cos 99% of users don’t have that - they have the defaults. Bringing it home, Clojure is a great example of why defaults matter.

I like ~ though, better default :)

@dominicm gremlin is basically Groovy. Not the best choice IMO.

@thomas I think the RDS proxy is only for Aurora?

Or am I thinking about the Data API?

@slipset in what way is it basically Groovy? Is it implemented in Groovy?

g.V.has('name','hercules').out('father').out('father').name is an example query.

The implementation we’re using is implemented in/backed by Groovy which leads to all kinds of great surprises.

Since it’s accepting any groovy code.

So you can do g.V.map(my_own_fn)

Does anyone know how I can force Clojure highlighting in a gist? https://gist.github.com/borkdude/e6f0b12f9352f3375e5f3277d2aba6c9

call the gist somehting.clj

Which you’ve done…

https://gist.github.com/slipset/2ab95293a4ae6a4d614377544bae86d1

I'm using a shebang which confuses github apparently

it helps putting the shebang to the second line but it will of course break it.

@borkdude ooor put #!/usr/bin/env bash# looks ugly but seems to work for both shebang and highlighting

I've seen some inline-comment hint recently to set the language. I should have written it down

@slipset I think there's a clojure implementation kicking about. Anyway, that's way better than the neo4j cypher dsl:

(query g "social"
         (.render cypher-renderer (.build (.returning
                                            (Cypher/match (into-array [(.. (Cypher/node "person" []) (named "a"))]))
                                            (into-array ["a"])))))

I'm planning to try and load clojure code into redisgraph and see about querying it.

@slipset things like https://github.com/clojurewerkz/ogre look nothing like groovy of course. So I think it's all down to the library you use as to what syntax you get.

Luckily we’ve exposed the non-data thing to our customers, so we’re locked in.

btw I found a solution for the highlighting problem

@slipset you, uh, expose raw gremlin to your customers?
