Let’s say that, in a Boot task, I want to modify a resource on my classpath for a downstream task, and keep it at the same location. Is it bad to directly the modify the resource directly using ?

@cigitia: it's better to copy and rm, https://github.com/adzerk-oss/boot-template is an example

@alandipert: I see; thanks.

@alandipert: If it’s a specific resource that I want to modify, is there a better way of getting its File object from the input fileset other than using ?

@cigitia: check out boot.core/tmp-file

it sounds like the private copy function in boot-template may do close to what you want

it makes use of tmp-file

@alandipert: The thing about that, though, is that tmp-file requires that I’ve obtained a temp-file object from the fileset already.

My problem is that I need to retrieve a specific input file at a specific path from the fileset.

I’ve been using io/resource for that.

i see

for the finding part, i think you want boot.core/by-name

err, 1 sec

i find better example

@alandipert: Thanks!

yeah, so to get a list of files from the fileset, you use the 'query' api - https://github.com/boot-clj/boot/wiki/Filesets#fileset-queries

boot.core/by-name’s design sort of confuses me.

by-name is expecting the objects returned by a query

e.g. (by-name ["foo.bar"] (input-files fs))

Ah, ah.

Now I understand.

in the boot-template thing i do my own by-name on https://github.com/adzerk-oss/boot-template/blob/master/src/adzerk/boot_template.clj#L40, can't remember why

I might edit the wiki to talk about how to use by-name then later.

Thank you so much!

that would be excellent, thanks in advance!

no prob

Is there a way to create a package on cljsjs with a optional dependency but participate on the dependency graph? Eg. vega optionally depends on d3-cloud (only for word clouds). But when it does vega should be loaded before d3-cloud.

@alandipert: Is there a particular reason why, given a resource-file-path, (->> fileset boot/input-files (filter (comp #{resource-file-path} :path))) …would successfully get the resource file that I want, at the same time that… (->> fileset boot/input-files (boot/by-name [resource-file-path])) …gives an empty collection? I’m checking the source at https://github.com/boot-clj/boot/blob/master/boot/core/src/boot/core.clj#L877, and it seems like it should have worked.

@cigitia: you can also easily access files by their full path doing something like this (get-in fileset [:tree "public/index.html"]) I'm not 100% sure if this is a ”public“ api feature, maybe @micha can comment on that.

@cigitia: it's important that you never write to a file in the fileset directly

they're set to be read-only via file permissions, but you could get around that i'm sure

the way you can replace a file in the fileset with another file is to create a new file in a temp dir such that the new file has the same relative path as the one you want to replace, and then add the temp dir to the fileset.

Hello, is there a clojure & clojurescript boot template somewhere ?

I found this https://github.com/Deraen/saapas but it fails on first task for me

Or is it not intended to be used like that ?

@nha: What's the problem? It should work and it should be okay to use as a template

@juhoteperi: ah hello Well I just opened an issue if you want to look at it https://github.com/Deraen/saapas/issues/6

Maybe it's me, but I can't figure what I've done wrong

@nha: Aha, that's caused by old Boot binary

boot -u only updates Boot library, you'll have to download new binary yourself

oh ? I'm pretty new to boot, sorry. What do I have to update ?

https://github.com/boot-clj/boot#install

Either dowload http://boot.sh/exe or upgrade boot-clj package with brew

ah right ! I skimmed that part !

Oh wait, I used brew

I unlinked, relinked using brew, ran boot-u again and now it's compiling

Well thank you, I will close the issue

I think brew update && brew upgrade boot-clj should work also

update updates the package repository and upgrade upgrades the package

I see, but I had 2.0 already

but thanks for the tip anyway

Latest binary is 2.3 and latest in Brew is 2.2

ow 😕 alright then

^^

the change to the boot binary in 2.3.0 is very minor

only fixes a bug where something like BOOT_JVM_OPTIONS='-Dfoo="something with quotes"' boot ...

the quotes weren't being properly preserved

@juhoteperi: works perfectly

Is there a canonical way to include development variables / dependencies ?

I guess I have to use set-env!, correct ? does it really set or is it more of a merge ?

set-env! is to configure the classpath of your build process

it sets

there is also merge-env! which will intelligently merge

or you can do (set-env! :dependencies #(conj % '[some.new/dependency "1.2.3"]))

that will also merge

ok so if I want a dev/user.clj repl available, I should add (set-env! :source-paths #{"src" "dev"}) to my task ?

ok that's clear thanks

so I get that I have to do (1) boot dev (2) cider-connect (3) (start-repl) to get a cljs-repl

What are the advantages of doing that ? It means I never have to relaunch a repl ? Or is there a shorter way to get a cljs repl ?

does someone here have a boot profile to share ?

you are programming now, nha

the workflow of your dreams is only a few clojure functions away

ahaha right

if you want to automate things you can: boot tasks compose with each other and with your own tasks

yep that's what sold me over (that and my lein file was becoming too big)

and you can start developing your task in the repl or an emacs buffer

you can reload your build.boot in the repl by doing (load-file "build.boot")

you'll probably need that

just like emacs ^^

so instead of using lein plugins, I should put them in boot.repl, correct ?

(I'm thinking of clj-refactor specifically)

i'm not familiar with boot.repl, is that something clj-refactor uses?

well I found that here : https://github.com/boot-clj/boot/wiki/Cider-REPL

oh right, yeah those are dynamic vars that the repl task will use to load dependencies that are specific to repl stuff

the repl is a weird task because it's basically like starting a debugger

but yeah those dynamic vars are how you configure the repl with middleware

Thanks a lot ! I will play a bit around

@raywillig: i can't reproduce that

can you try again?

@raywillig: oh wait, i can reproduce

@micha any idea how to make it terrific?

@raywillig: I get that when running boot in a directory where there is no boot file ?

i think i need to push a new release probably

man i dunno

trying to deploy boot to clojars using leiningen

keeps failing

looks like a case of mangled clojars metadata https://github.com/ato/clojars-web/issues/369

@micha: I can fix that checksum issue manually, but not right now :( Can you file an issue at ato/clojars and I can fix it first thing in the AM

@tcrawley: sure! i was in the middle of checking metadata for the various artifacts when i accidentally typed rm -rf ~ and pressed enter before the rest of that command ... /.m2/repository/boot

lol

it's amazing how fast things can be deleted
