icon_emoji bug? about slackr HOT 8 CLOSED

I'm having the same issue. My team wanted to use this functionality to get updates on automated code runs, with a happy face when the code successfully runs and a sad face when an error is thrown.

slackr("Good Message", channel = "xxx", icon_emoji = ":grinning:")

Just wanted to check if there has been any development on this issue

I am having the same issue here with icon_emoji. Has this been resolved lately?
slackr_msg(text = 'new text', as_user=FALSE, channel='@me', username='bot', icon_emoji = ":cat:")

Username changes but icon_emoji does not.

@havlikp @jh-206 Work around:
I think there is an issue with the package itself. The function is defined as :

function (txt = "", channel = Sys.getenv("SLACK_CHANNEL"), username = Sys.getenv("SLACK_USERNAME"), icon_emoji = Sys.getenv("SLACK_ICON_EMOJI"), api_token = Sys.getenv("SLACK_API_TOKEN"), ...) { if (api_token == "") { stop("No token specified. Did you forget to call slackr_setup()?", call. = FALSE) } if (icon_emoji != "") { icon_emoji <- sprintf(", \"icon_emoji\": \"%s\"", icon_emoji) } output <- paste0(txt, collapse = "\n\n") loc <- Sys.getlocale("LC_CTYPE") Sys.setlocale("LC_CTYPE", "C") on.exit(Sys.setlocale("LC_CTYPE", loc)) resp <- POST(url = "https://slack.com/api/chat.postMessage", body = list(token = api_token, channel = slackr_chtrans(channel), username = username, icon_emoji = icon_emoji, text = output, as_user = TRUE, link_names = 1, ...)) warn_for_status(resp) return(invisible()) }

The if statement that parses the 'icon_emoji' input results in a string of text that looks like:
, \"icon_emoji\": \":zzz:\"
(assuming that 💤 is the emoji input)

a workaround could be to post to the api directly via the POST function:
output <- 'some text'
output <- paste0(output, collapse = "\n\n")
resp <- POST(url = "https://slack.com/api/chat.postMessage", body = list(token = api_token, channel = slackr_chtrans(channel), username = username, icon_emoji = ':zzz:', text = output, as_user = FALSE, link_names = 1))

you can pass the emoji as part of the msg

slackr_msg(txt = ':zzz:')
slackr_msg(txt = ':face_with_rolling_eyes:')

@hrbrmstr is the icon_emoji param a legacy param?

Thanks. I like using slackr() because it makes it obvious visually which messages were sent from R and which messages were not. But the emoji will be super useful for scanning for error messages, so I guess I'll use slackr() to send the system time and potential error messages, and then use slackr_msg() after to send emoji indicating success or error.

Appreciate the help!

It sounds like you would be better off to use ‘register_onexit’ and send a summary output to slack when your process is done. See bottom of readme for examples

Yeah hadn't seen that function as I've been working off the CRAN version of the package. Will look to incorporate, thanks
