is it a bummer that clojure.walk/{pre,post}walk-replace only accepts a map for replacements, and not a function? Without the contains?, you could pass any function to the replace-fns. (postwalk (fn [x] (if (contains? smap x) (smap x) x)) form))

(defn recursive-replace
  "Recursive find and replace. Will replace anything with anything regardless of whether it's in a list, a map, a set or any of those   nested one inside another. No pattern matching. Naive implementation. Is probably slow."
  [form sym replacement]
  (let [once-more (partial map #(recursive-replace % sym replacement))]
    (cond
      (map? form) (into {} (once-more form))
      (vector? form) (into [] (once-more form))
      (set? form) (into #{} (once-more form))
      (seq? form) (once-more form)
      (= form sym) replacement
      :else form)))
From the above. It's probably hacky, but it seems to work.

without the contains? it would be just the same as prewalk or postwalk 馃槈

I'm trying to make an clj-http.client request to a third-party webpage, but am getting the following error response:

Spaceman12:05:54

Where the response says "no-js ie 6 oldie". How do I fix this?

j12:05:51

you may try a "real" user agent string, cloudflare thinks you are a bot (i think)

j12:05:40

try with curl also

Spaceman12:05:10

with curl it works

Spaceman12:05:25

what's a real user agent string?

Spaceman12:05:36

I think it's because cli-http's infrastructure is outdated.

Spaceman13:05:42

no actually it doesn't work with curl either

Spaceman13:05:56

I thought it was a 200 but it is also a 4093

Spaceman13:05:28

what's a real user agent string?

j13:05:08

not sure it will solve your issue (non clojure related) but a user agent header firefox would send for instance

Spaceman13:05:35

would you please give an example?

aisamu13:05:36

open FF, devtools, network tab, load a random page, right click on any request and pick copy as curl

Spaceman13:05:26

that gives:

I was referring to "a user agent header firefox would send for instance" - fetch the header params from the generated curl command

There's an #etaoin channel, they might be more well equipped to help you

simongray13:05:58

can I dynamically rebind = somehow? binding won鈥檛 allow me to do it and with-redefs sounds like something that shouldn鈥檛 be used outside testing. My use case is wanting to compare two aggregate hiccup-like data structures using =. I want to handle the fact that certain hiccup vectors should be considered equivalent in this particular scope, but not otherwise.

val_waeselynck15:05:18

You could also wrap them in a deftype that redefines .equals() and .hashcode() I guess

simongray13:05:11

Thanks, Alex. Well that sucks. What is motivation for not allowing it since 1.3?

Alex Miller (Clojure team)13:05:01

performance - this affects every var resolution in your program. there is always a tradeoff between performance and dynamicity

Alex Miller (Clojure team)13:05:48

from a general pov though, Clojure has worked very hard to define equality with value semantics - it is an underappreciated part of working well with immutable values

Alex Miller (Clojure team)13:05:31

redefining equality is often a tempting idea. in my experience, it's nearly always a bad idea

馃挴 12
simongray13:05:58

Yeah, I totally agree that the equality semantics are quite under-appreciated, especially considering they enable so many of the nice things about the rest of the language. I just wish I could hook into it in this one case鈥

Alex Miller (Clojure team)13:05:06

if you want a way to compare data structures for your own notion of whatever, make a new function

馃挴 4
Alex Miller (Clojure team)13:05:18

or move the differences into metadata

simongray13:05:52

Right. My primary concern is that this in an aggregate tree structure. Clojure鈥檚 equality essentially allows me to do (= agg1 agg2) and get it evaluated recursively. I guess I will have to make my own special= that zips through the aggregates in parallel and compares each node鈥 or something.

simongray13:05:45

At least that鈥檚 the only other idea I have at the moment.

didibus15:05:34

You can still create your own types with your own implementation of equals no?

simongray15:05:25

@U0K064KQV Yes, but I specifically need to compare bespoke hiccup that conforms to a certain shape. My use case is the following: [:div 1 2 3] should be considered equal to e.g. [:div 鈥 and it needs to apply recursively for any two hiccup-like structures. I鈥檓 on my way to solving it now (using two zippers that I zip through in parallel).

Alex Miller (Clojure team)15:05:25

is there a data transformation that could be easily applied before comparing equal?

simongray15:05:56

@U064X3EF3 Hm, not that easily. I want to capture values from one hiccup-like structure using symbols found in the other in the same place. It鈥檚 a mini-DSL for doing hiccup data transformations. It has been working great so far for structures with a similar structure, but it鈥檚 a bit tricky to implement the same pattern for capturing values in variadic vectors.

didibus19:05:19

Ya, best to create a tag= function or something like that instead

didibus19:05:37

More readable in my opinion as well then

Karol W贸jcik14:05:10

Schema.core question: Is it possible to not throw an error when additional keys are provided to some map and those does not match the schema?

noisesmith14:05:42

I always addressed this by adding s/optional-key s/Any as an entry to my schema map

noisesmith14:05:05

this is the default behavior of clojure's native spec library btw

Karol W贸jcik14:05:21

I would rather not do it for the pedestal.request map, since by definition it's dynamic

Karol W贸jcik14:05:23

Ok.. Wil do it on my own:

(s/check s (select-keys req (keys s)))

noisesmith14:05:44

yeah, select keys vs. assoc optional-key / Any comes out to about the same

orestis14:05:55

hello, question about deps, I have a project in which I have a script to run some formatting code, it looks like: clojure -Sdeps '{:deps {mvxcvi/cljstyle {:git/url "" :sha "e4cda0cc49901622d5c266a315881d5b10c54e27"}}}' -m cljstyle.main check src test the problem is that, when I run this on the pipeline, I have some deps that can't be fetched there, but I don't need those deps to run this command. Is there a way to tell clojure to ignore all deps.edn and just use the deps from -Sdeps?

Alex Miller (Clojure team)22:05:52

if you create an alias, and use :deps in the alias, that will replace not augment (like :extra-deps) the project deps

Alex Miller (Clojure team)22:05:18

clojure -Sdeps '{:aliases {:check {:deps {mvxcvi/cljstyle {:git/url "" :sha "e4cda0cc49901622d5c266a315881d5b10c54e27"}} :main-opts ["-m" "cljstyle.main"]}}}' -A:check check src test

Alex Miller (Clojure team)22:05:46

but I'd really recommend putting that :check alias in your ~/.clojure/deps.edn aliases so you don't need to put any of that on the command line

Alex Miller (Clojure team)22:05:08

then you can invoke that tool from any project with just clj -A:check check src test

馃憤 8
wilkerlucio22:05:17

it worked on my local machine but not on Github actions, I got Error building classpath. Unknown alias key: :deps there, is this a version issue?

wilkerlucio22:05:15

you know which version has this? I'm using tools.deps 1.10.1.469 in the pipeline

Alex Miller (Clojure team)23:05:13

there are some bug fixes after then though - latest is 1.10.1.536

Alex Miller (Clojure team)23:05:14
