Inline Queries - answer direct queries to bot

You must include source modules/inline.sh in 'commands.sh' to have the following functions availible.

Inline Queries allows users to interact with your bot directly without sending extra commands. As an answer to an inline query you can send back one or more results to the Telegram client. The Telegram client will then show the results to the user and let him select one.

answer_inline_query

answer_inline_query is provided for backward compatibility with older versions of bashbot. It send back only one response to an inline query.

usage: answer_inline_query "$i{QUERY[ID]}" "type" "type arg 1" ... "type arg n"

example: - see Advanced Usage

answer_inline_multi

anser_inline_multi allows you to send back a list of responses. responses must be seperated by ','.

usage: answer_inline_multi "${iQUERY[ID]}" "res, res, ... res"

example:

# note the starting " and ending " !!
answer_inline_multi "${iQUERY[ID]}" "
    $(inline_query_compose "1" "photo" "https://avatars0.githubusercontent.com/u/13046303") ,
    ...
    $(inline_query_compose "n" "photo" "https://avatars1.githubusercontent.com/u/4593242")
    "

inline_query_compose

inline_query_compose composes one response element to to send back.

usage: inline_query_compose ID type args ....

	ID = unique ID for this response, 1-64 byte long
	type = type of answer, e.g. article, photo, video, location ...
	args = mandatory arguments in the order they are described in telegram documentation

Currently the following types and arguments are implemented (optional arguments in parenthesis)

	"article"|"message"	title message (markup description)

	"photo"			photo_URL (thumb_URL title description caption)
	"gif"			photo_URL (thumb_URL title caption)
	"mpeg4_gif"		mpeg_URL (thumb_URL title caption)

	"audio"			audio_URL title (caption)
	"voice"			voice_URL title (caption)
	"document"		title document_URL mime_type (caption description)

	"location"		latitude longitude title
	"venue"			latitude longitude title (adress foursquare)
	"contact"		phone first (last thumb)

	"cached_photo"		file (title description caption)
	"cached_gif"		file (title caption)
	"cached_mpeg4_gif"	file (title caption)

	"cached_document"	title file (description caption)
	"cached_video"		file title (description caption)
	"cached_voice"		file title (caption)
	"cached_audio"		file title (caption)

see InlineQueryResult for more information about response types and their arguments.


Background and Interactive jobs

You must include source modules/background.sh in 'commands.sh' to have the following functions availible.

start_proc

startproc starts a script, the output of the script is sent to the user or chat, user input will be sent back to the script. see Advanced Usage

usage: start_proc "${CHAT[ID]}" "script"

alias: startproc "script"

example:

startproc 'examples/calc.sh'
check_proc

Return true (0) if an interactive script is running in the chat.

usage: check_prog "${CHAT[ID]}"

alias: checkprog

if ! check_proc "${CHAT[ID]}" ; then
  startproc "examples/calc.sh"
else
   send_normal_message "${CHAT[ID]}" "Calc already running ..."
fi
kill_proc

Kill the interactive script running in the chat

usage: kill_proc "${CHAT[ID]}"

alias: killproc

example:

if check_proc "${CHAT[ID]}" ; then
  killproc && send_message "${CHAT[ID]}" "Command canceled."
else
  send_message "${CHAT[ID]}" "Command is not running."
fi

start_back

Starts a script as a background job and attaches a jobname to it. All output from a background job is sent to the associated chat.

In contrast to interactive chats, background jobs do not recieve user input and can run forever. In addition you can suspend and restart running jobs, e.g. after reboot.

usage: start_back "${CHAT[ID]}" "script" "jobname"

alias: background "script" "jobname"

example:

background "examples/notify.sh" "notify"
check_back

Return true (0) if an background job is active in the given chat.

usage: check_back "${CHAT[ID]}" "jobname"

alias: checkback "jobname"

example:

if ! checkback "notify" ; then

  background "examples/notify.sh" "notify"
else
 send_normal_message "${CHAT[ID]}" "Process notify already running."
fi
kill_back

usage: kill_back "${CHAT[ID]}" "jobname"

alias: killback "jobname"

example:

checkback "notify"
if [ "$res" -eq 0 ] ; then
  send_normal_message "${CHAT[ID]}" "Kill notify"
  killback "notify"
else
  send_normal_message "${CHAT[ID]}" "Process notify not run."
fi

send_interactive

Form version 0.80 on forward_message is used to forward messages to interactive job. It replaces the old 'inproc' commands used for TMUX. Usually message is automatically forwarded in 'commands.sh', but you can forward messages wihle processing also or send your own messages.

usage: send_interactive "${CHAT[ID]}" "message"

replaces:' incproc
