I am trying …. for a CLI app to provide options & usage

there are two excellent node libs command-line-args and command-line-usage

command line-args integrates very easily

but am having some trouble with command-line-usage

has anyone seen this before?

@raymcdermott are you not using :target :node-script?

yes

I am using that

standard stuff afaik

right, sorry I was confused for a sec.

this is using the code directly from node_modules without any processing

not really sure why it would fail

do you maybe call it with nil?

I don’t think so …. checking

you can try running node package/main.js --inspect-brk and then turn on pause on exceptions

then check the stack to see what value was used to call the failing function

UNKNOWN_OPTION: Unknown option: --inspect-brk

node --inspect-brk package/main.js ?

yes

should show the node process then

it gives an error on domain.js

NOENT

no idea. doesn't seem to be the exception you are looking for. does it work if you just let it run again?

no, then same error on bootstrap_node.js

then module.js

then internal/module.js

then the error I posted

that is misleading, the error occurs while your code is LOADING not while it is executing

probably because you run the function directly

oh yes, I do that

if you run it inside vouch-admin-cli.main/main the exception might be clearer

it runs inside main

sorry, misunderstood what you meant there

oh right sorry.

ok bascially what happens is that shadow-cljs appends a file that contains (vouch-admin-cli.main/main ...)

this causes your main function to run

and your main function throws

because shadow-cljs was still loading the file it is one the stack

but it has nothing to do with shadow-cljs

https://github.com/thheller/shadow-cljs/blob/master/src/main/shadow/cljs/node_bootstrap.txt#L49-L50

so is it the transitive dep?

no. it just seems to confuse the debugger

oh

you should get to node_modules/command-line-usage/lib/chalk-format.js:8:13 in the debugger

don't know why it would show module.js and the other stuff

I do

oh?

it’s giving str = undefined

which is the arg being passed it

chrome should show the stack

just go up the stack until you see how it got to be undefined

doing…

hmm

npx shadow-cljs node-repl

(ns foo.bar (:require ["command-line-usage" :as x]))

(x (clj->js [{:header  "My CLI"
              :content "Manage your environment"}
             {:header     :Options
              :optionList [{:name        "create-xxxx"
                            :alias       :c
                            :typeLabel   "{underline name}"
                            :description "Create xxxx with that name"}
                           {:name        "help"
                            :alias       :h
                            :description "Print this usage guide."}]}]))

"
 My CLI\r
 \r
   Manage your environment \r
 
 Options\r
 \r
   -c, --create-xxxx name   Create xxxx with that name \r
   -h, --help               Print this usage guide.    \r
 "

I have some entries without a :description key

and that breaks it !

ha!

if only JS had spec

hehe

thanks vm for your help

would have wasted a shit ton more time

and I know I can debug with chrome now 🙂

I’m still loving those libs though

Is it possible to specify dependencies directly from github?

Hi Channel! Is there an tutorial entry on how to combine server clj run by leiningen with shadow-cljs? In a manner of how figwheel does that I can do a tutorial entry for that, if you explain. p.s. the tool is awesome, great thanks to the author and conrtibutors UPD: found a proper example, thanks

@grav it is possible if you use deps.edn. directly from shadow-cljs no

@thheller even though shadow-cljs didn’t make top two to be funded by clojurists together - good to see it come in a strong #4 - good exposure. Perhaps next round! https://www.clojuriststogether.org/news/q2-2018-funding-announcement/

Yeah it was a good application and we would have liked to fund it if we had more money
