I want to add cljs-time to my klipse blog … is this supported? [https://github.com/andrewmcveigh/cljs-time]

You need to try

I have seen the blog post http://blog.klipse.tech/klipse/2016/10/16/klipse-is-fast.html

but cannot see how to bring a CLJS lib in

It’s not explained here

that’s a relief 😉

You need to have a klipse snippet with data-external-libs=<https://raw.githubusercontent.com/andrewmcveigh/cljs-time/master/>

And the content of the snippet will something like : require '[cljs-time.core :as t]

data-external-libs is like the classpath

I’ll give it a go

it tells klipse where to resolve the namespaces

I saw that

but wasn’t sure how to form the URL for the lib

I guess I could also use a tag rather than master

yes

it might be a better idea

I’d appreciate if you could improve the instructions for using external libs

it confuses a lot of people

sure - if I get it to work, I’ll try to help

Awesome:metal:

it’s not working yet so don’t get to excited 😛

ah

#error {:message “No such namespace: cljs-time.core, could not locate cljs_time/core.cljs, cljs_time/core.cljc, or Closure namespace \“cljs-time.core\“”, :data {:tag :cljs/analysis-error}}

this is the code I have…

sorry, I made a mistake in the data-external-libs

It has to be: data-external-libs=<https://raw.githubusercontent.com/andrewmcveigh/cljs-time/master/src>

Notice the src at the end

yes, makes no difference

maybe it should have /cljs_time also

no

what error do you see now?

no 🙂

#error {:message “No such namespace: cljs-time.core, could not locate cljs_time/core.cljs, cljs_time/core.cljc, or Closure namespace \“cljs-time.core\“”, :data {:tag :cljs/analysis-error}}

I am doing it within a deckjs presentation

It shouldn’t make a difference

Let me try

I thought not but mention it for completeness

What’s the topic of your presentation?

It’s a bunch of jokes about Clojure and FP, written in Clojure

I previously had to swap between keynote and the terminal

and I would rather do it all in one 🙂

Yeah!

for example I make a macro called joke that can be called with a story and a punchline

but it has no side effects

and jokes should always have a side effect

otherwise it’s a quantum joke

I'm screenshoting that

what?

The four sentences, out of context it's hilarious

LOL, it’s meant to be a joke so I’m happy about that 🙂

I can see I’m going to have t o be careful not to reveal too much here!

It was last year's EuroClojure where you did a clojure jokes "unsession" or something, right?

yes, I’m hoping to do the same this year too

I have an unsession booked at least

Cool, I'll probably book my ticket and flight sometime this week, when are the unsessions?

normally on the Thursday evening

Perfect, I was disappointed not to go to EuroClojure last year, hopefully I'll see your unsession this year.

that would be great

@raymcdermott I think I found the issue

Could you try

(require 'goog.i18n.DateTimeSymbols
         '[cljs-time.core :as t])

?

#error {:message “Could not eval my.klipse”, :data {:tag :cljs/analysis-error}, :cause #error {:message “Only :as alias, :refer (names) and :rename {from to} options supported in :require; offending spec: (quote goog.i18n.DateTimeSymbols) at line 1 “, :data {:file nil, :line 1, :column 1, :tag :cljs/analysis-error}}}

can you show me the page source?

#error {:message “Could not eval my.klipse”, :data {:tag :cljs/analysis-error}, :cause #error {:message “Only :refer-clojure, :require, :require-macros, :use, :use-macros, and :import libspecs supported. Got (require (quote goog.i18n.DateTimeSymbols) (quote [cljs-time.core :as t])) instead. at line 1 “, :data {:file nil, :line 1, :column 1, :tag :cljs/analysis-error}}}

I used :require, not require first

That should work also

oh no!

You cannot put (require) inside a ns

You have to use :require

but without the quotes

I had that… but OK let me revert

Also it is better to put the require statement in a separate snippet

Then it is not re-evaluated when you modify your code

#error {:message “No such namespace: cljs-time.core, could not locate cljs_time/core.cljs, cljs_time/core.cljc, or Closure namespace \“cljs-time.core\“”, :data {:tag :cljs/analysis-error}}

also, you have a typo

It should be

<code class="clojure"
              data-external-libs="https://raw.githubusercontent.com/andrewmcveigh/cljs-time/master/src/">

LOL yes the typo

OK, it’s working now!!

COOL!!!

does Klipse support macros (I assume yes)

yes

OK, let me play with that and I promise to do a little write-up on external libs

When using macro, you have to do a special trick with the namespace

See http://blog.klipse.tech/clojure/2016/05/01/macro-tutorial-1.html

And be careful not to create more than 1 ns in your presentation

otherwise it’s going to be a big mess

Good tip!

And I have a surpris for you

While we were talking, I have added cljs-time to the analysis cache of Klipse

so can I put the ns/require in a snippet at the top and assume it’s going to be usable everywhere?

correct

haha, cool

Starting from Klipse version 7.1.1

you don’t need the data-external-libs

in order to use cljs-time

and it loads much faster

so will that get picked up automagically now?

exactly

I mean “http://app.klipse.tech/plugin/js/klipse_plugin.js” is now 7.1.1?

yes

sweeeeet!

You can check the browser console

to see what version you get

ok, I’ll give it a shot

boom, yes that works

something else I’m having an issue with…. hiding code

if I do this

I get this

the snippet is not hidden at all!!

you see my problem

quite literally

You need to create a css rule that hides element with class hidden

something like

oh, I thought that was with klipse

.hidden {
visibility: hidden
}

It’s not part of klipse

it’s in the manual

is it form the gitbook?

yes

that’s because gitbook has such a css rule

Probably, I need to make it clearer

haha ok

the css rule does not collapse the space that the code would have occupied

I’m not a CSS guru

so any clues would be appreciated

.hidden { display: none; }

does the right thing - the visibility CSS rule is literally bullshit

I have the macros working now too - so that’s cool and the gang
