Beginner friendly Readme tutorial :)

First off, thanks for this wonderful API client in OCaml
! I am new to OCaml
and I was going through the GitHub
repos to find something I could really learn from and here it is - a slack
client π
However, being a beginner I'm unable to really start using this in utop
This is my progress so far
#require "slacko"
utop # Slacko.auth_test ( Slacko.token_of_string "my-token-string" );;
Characters 19-41:Warning 3: deprecated: Slacko.token_of_stringPlease use 'start_session' instead.

Could you please help me out a little bit here ?
Thanks for the kind words!
It is odd, because the error is that the HTTP library you're using does not have SSL/TLS support, which is necessary to talk to the Slack API. The OPAM file mentions this, so installing the package should install either the ssl
or the tls
package.
How did you install slacko
?
Found solution for the tls
problem atleast hammerlab/ketrew#420
Yes, but it should not be necessary because slacko
already depends on tls
or ssl
so it should be installed automatically.
Hmm, I realized this however I keep running into errors while building a transitive dependency mirleft/ocaml-tls#385
It looks like you're running opam
as root and your ~/.opam
is corrupted. I would recommend you to run it as regular user and maybe start from a clean ~/.opam
.
Mmm, actually I am trying out a server ( for the first time ! ) and I the only way I have access to it is ssh root@xyz
and this is the reason I installed everything as root.
I don't quite know how to create user and run ocaml as a user, could you please point me in the right direction ?
I don't know which operating system your server uses, here's the instructions for Debian GNU/Linux.
Well it can all be done if you know what you're doing, but the problem is that you'll need to install OPAM 2 and I am not sure there are prebuilt packages for OPAM 2 for ARMv7. Therefore I would suggest you start with a simpler platform first.
I think posting a message is quite self-explanatory. If you look in the documentation you'll find chat_post_message
, which among other optional arguments requires a token
, a channel
and a message
type. In the module you can find channel_of_string
, message_of_string
and token_of_string
to construct these types of of strings. Then it is just a matter of calling the function and resolving the Lwt promise. You can see this thing being done in the bundled slack-notify
program:
slacko/src/cli/slack_notify.ml
Line 73 in 5c2ac37
(It seems like the API docs are out of date for some reason, looks like I'll have to look into it)
Hi @Leonidas-from-XIV , have you managed to find time to update the docs
yet ?
Yes, sorry, the docs should be up to date with the current release on OPAM.
