lumo
@onetom has joined the channel
i was just giving a try to lumo -n 5555 -D kitchen-async:0.1.0-SNAPSHOT using a tubular socket repl client from cursive eap8.
my main use-case would be exploring http apis interactively, which is why i pulled in kitchen-async, hoping to ease the experience, but it breaks badly at the boundaries and im not sure what to do about it.
when an expression evaluates to a Promise i wont see what it resolves to.
if i tuck a (p/then the-promise-im-interested-in prn), then it will be printed on the terminal (but not always :/) where i started lumo, instead of the socket repl client, in the cursive repl window
im wondering how others would deal with this
ah, yeah, the multi-line expressions are also printing a bunch of secondary prompts but after it appears in the cursive console and all on one line, so the output is quite a mess. i was looking at the source hoping to replace the prompt strings, but it seems the repl.js:prompt() function is not exposed in the cljs context.
im envisioning something like an automatic wrapper around promise return values with automatic printing of the resolved value, a timeout and a default .catch...
@onetom what is p in p/then, it's usually (-> a-promise (.then (fn [res] ..do smth..))). Did you try enabling dumb-terminal for the console logs, does it make a difference?
flag:
-d, --dumb-terminal
haven't thought about that, but let's see
doesn't make a difference
I guess then it's better to start the client in cursive, instead of socket-repl client. But not unlikely that you can transfer the logs over the socket, don't remember how it was, but I think stdout is transfered and stderr messages not. But let's see if someone else knows a better way.
what do you mean by "start the client in cursive"?
I'm not a cursive user, but I mean, skipping the -n 5555 and just start lumo with shell command from within the cursive terminal (I suppose there's one there?)
I should use the word IntelliJ* as Cursive is just a plugin. But do note that there's quite small support for lumo in text editors, even in Emacs where all we have is inf-clojure mode.
yeah, you can start it in a terminal, but that doesn't have any integration with the file editor area, so i can't send forms over to it... 😕
i was trying the custom socket repl accept function in lumo 1.9.0-alpha, but it seems to be ignored:
cljs.user=> dusty:lumo onetom$ lumo -n '{"port":5559, "accept":"XXX"}'
Lumo 1.9.0-alpha
ClojureScript 1.10.238
Node.js v9.10.1
...
Lumo socket REPL listening at localhost:5559.
cljs.user=>
dusty:lumo onetom$ nc localhost 5559
Lumo 1.9.0-alpha
ClojureScript 1.10.238
Node.js v9.10.1
...
cljs.user=> 123
123
cljs.user=>
i was expecting to see an error, since XXX is obviously a bogus function reference.
i was trying with lumo -n '{"port":5559, "accept":"ethlib.repl/accept"}' originally of course, where
src/ethlib/repl.cljs is :
(ns ethlib.repl)
(defn accept [socket & args]
(.end socket (str "\nHello friend.\nYou gave me the following args: " args "\n\n")))
i thought i would debug it by building my custom lumo, but it depends on the 5.90 GB Xcode... <sigh>
@onetom you can run lumo in development without compiling the C++ code
as long as you have Node.js installed
btw I’m sorry the workflow is so rough
but I don’t really use IntelliJ so I can’t really help
wrt to your latest question though, have you included the folder where the ethlib.repl namespace is in the classpath?
it's in the src/ dir, which i would guess is in the class path, but i tried it with lumo -c src/ -n ... and it makes no difference
how can i run a modified version of lumo without boot release?
how are you using the lumo repl usually?
you can run the development version with boot dev
as long as you have Node.js installed
i just tried an earlier lumo (installed with brew install lumo) and it doesn't complain about the bogus accept function either:
dusty:lumo onetom$ lumo -n '{"port":5559, "accept":"XXX"}'
Lumo 1.8.0
ClojureScript 1.9.946
Node.js v9.2.0
...
Lumo socket REPL listening at localhost:5559.
cljs.user=>
because the function hasn’t been run
it’ll probably fail if you telnet localhost 5559
that said, it looks like 1.9.0-alpha has a bug where it doesn’t run the accept function
mind opening an issue?
indeed it did fail!
the function is only run when you connect to it
sure, i thought so, that's why i was showing above a connection attempt too.
im getting these circular dependency messages when i run boot dev:

is that expected?
yes
JS can have circular deps
then the build/ folder is empty 😕
yeah, i read the docs on the nodejs circular dependency handling the other week... it a weird choice how they just ignore it... 😕
i really wanted to debug this, but i guess i will just try to use the older version first, since that works
I managed to run the development version with node target/bundle.js -c target/ after starting boot dev.
i think it worth mentioning it in the README, because it's not very obvious
@onetom there’s yarn dev
which you can run to start lumo in dev
or npm run dev
found https://github.com/anmonteiro/lumo/blob/master/CONTRIBUTING.md as i was making a pull request and yarn dev is mentioned there
