slackr_tex function

Post a tex output to a Slack channel

Unlike the slackr_dev() function, this one takes a tex object, eliminating the need write to pdf and convert to png to pass to slack.

slackr_tex(
  obj,
  channels = Sys.getenv("SLACK_CHANNEL"),
  token = Sys.getenv("SLACK_TOKEN"),
  ext = "png",
  path = NULL,
  title = NULL,
  initial_comment = NULL,
  thread_ts = NULL,
  ...
)

Arguments

• obj: character object containing tex to compile.
• channels: Comma-separated list of channel names or IDs where the file will be shared.
• token: Authentication token bearing required scopes.
• ext: character, type of format to return, can be tex, pdf, or any image device, Default: 'png'.
• path: character, path to save tex_preview outputs, if NULL then tempdir is used, Default: NULL.
• title: Title of file.
• initial_comment: The message text introducing the file in specified channels.
• thread_ts: Provide another message's ts value to upload this file as a reply. Never use a reply's ts value; use its parent instead.
• ...: other arguments passed to texPreview::tex_preview(), see Details

httr response object (invisibly)

Please make sure texPreview package is installed before running this function. For TeX setup refer to the c("Setup notes on ", "list("LaTeX")").

Note

You need to setup a full API token (i.e. not a webhook & not OAuth) for this to work Also, you can pass in add_user=TRUE as part of the ...

parameters and the Slack API will post the message as your logged-in user account (this will override anything set in username)
