Hi @nathanmarz, now this might be a noob question, but how would I go about getting rid of the following warning when building my lein project (which has specter in the depenendency graph):

WARNING: any? already refers to: #'clojure.core/any? in namespace: com.rpl.specter.impl, being replaced by: #'com.rpl.specter.impl/any?

clojure 1.9.0

@mbjarland ah i'll need to release a new version that renames those functions

I'm using midje for testing which in turn pulls in marick/suchwow which in turn pulls in specter 0.13.0...ah ok

do you want the dependency graph or any other details from my side?

no, that's fine

you'll need to open an issue with midje to update its dependencies

looks like it's really outdated

would be glad to, though it might be worth waiting until you do your update before creating the ticket

just checked, that function no longer exists in specter codebase so there are no warnings with latest version

ha, ok I'll create a ticket now then

oh apparently I knew about and fixed this a long time ago: https://github.com/nathanmarz/specter/blob/master/CHANGES.md#0131

unfortunate fact

suchwow (which is the immediate dep of midje) has not changed since the 6.0.0 version which midje is using

this brings to mind Rich's talk about dependency hell...

so I would have to file a ticket with suchwow and once they update, file a ticket with midje?

@mbjarland yea, it's an annoying problem with the jvm

but yes, that would be the approach to use

it would probably be a lot faster for you to just fork the projects yourself in the meantime

there is an existing PR on suchwow: https://github.com/marick/suchwow/pull/9

I created a ticket and referenced the pr, now we wait

https://github.com/marick/suchwow/issues/10

@nathanmarz (select [ALL (selected? :p1 ALL :name (pred= "wow"))] data) => this expression check for "wow" word, what if i want to check multiple different words

for example: all contains "wow" or contains "good"

(or (pred= "wow") (pred= "good")) ?

@abdullahibra replace (pred= "wow") with #{"wow" "good"}

great

what if i want to use custom function rather than match string? maybe regexp matcher for example

@abdullahibra you can insert any clojure function into a path

if it returns nil or false, it ceases navigation there

regexes are also natively supported, they navigate to every substring match

#{"wow" (fn [s] (re-find #"[g|G]ood" s))} this is right?

so (selected? #"aaa") would act as a filter

no, sets are interpreted just like a function

(since sets are functions in clojure)

you would want either (fn [s] (or (= "wow" %) (re-find ...))) or (selected? (multi-path (pred= "wow") #"[g|G]ood"))

multi-path within a selected? functions like an or

you may wish to look through https://github.com/nathanmarz/specter/wiki/List-of-Navigators

that's really cool

thanks man for this

for this data: [{:s1 "cool" :p1 [{:name "hello" :sen "good"} {:name "world", :sen "nothing"}]}, {:s2 "cool2" :p1 [{:name "wow", :sen "fine"} {:name "world",, :sen "none"}]}]

@nathanmarz helped me to extract all hash maps which match "wow" or regexp, and for multiple words i would like to do this: (selected? (apply multi-path [#"regexp1" #"regexp2"])) and what if i want to match two cases in the same time, so i want to catch the :name which has regexp and :sen which has also regexp

don't do (apply multi-path ...)

why ?

inefficient and unecessary

to match multiple cases just put multiple conditions consecutive in the path

what if i have big list of regexp?

what i would like to get any hash map which match any from regexp-list1 and regexp-list2 from two different paths

one path from :name and other from :sen

you can do the (apply multi-path some-list) but there will be ways to optimize that if you have perf problems

(selected? (multi-path :key1 :key2) (multi-path (pred= "wow") #"some-regex"))

that would check that either :key1 or :key2 is either "wow" or matches that regex

i got this

but if i would like to match :name is "wow" AND :sen is "good"

so i don't get match for :name "wow" and :sen "nothing"

[#(= "wow" (:name %)) #(= "good" (:sen %))]

without multipath ?

multi-path navigates to multiple paths

for "and", it's just multiple navigators in a row, for "or" it's (selected? (multi-path ...))

ah okay got this

these are just how those concepts emerge from navigation
