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

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 (parse_mode description)
"photo" photo_URL (thumb_URL title description caption parse_mode keyboard)
"gif" photo_URL (thumb_URL title caption parse_mode keyboard)
"mpeg4_gif" mpeg_URL (thumb_URL title caption parse_mode keyboard)
"video" video_URL mime_type thumb_URL title (caption parse_mode keyboard)
"audio" audio_URL title (caption parse_mode keyboard)
"voice" voice_URL title (caption parse_mode keyboard)
"document" title document_URL mime_type (caption description parse_mode)
"location" latitude longitude title

"cached_video" file title (description caption description parse_mode keyboard)
"cached_voice" file title (caption parse_mode keyboard)
"cached_audio" file title (caption parse_mode keyboard)
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
example:
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

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
JSON.sh DB
Since output of JSON.sh is so handy to use in bash, we provide a simple wrapper to read and write JSON.sh style data from and to files. File name is prefixed with BASHBOT_ETC and the suffix '.jssh' is added to file name! File names must not contain '..'
A 'jsshDB' file is a simple 'kay=value' storage.
Example: for file name:
# bashbot is installed in /usr/local/telegram-bot-bash, no BASHBOT_ETC set.
"myfile" -> /usr/local/telegram-bot-bash/myfile.jssh
"addons/myfile" -> /usr/local/telegram-bot-bash/addons/myfile.jssh
"${DATADIR}/myfile usr/local/telegram-bot-bash/data-bot-bash/myfile.jssh

jssh_newDB
Creats new empty jsshDB file if not exist.
usage: jssh_newDB "filename"
jssh_checkDB
Check if DB name respects the rules and returns the real/final path to DB file. Used internally by all jssh DB functions, but can also used to get the real filename for a jssh DB.
usage: jssh_checkDB "filename"
jssh_readDB
Read content of a .jssh file in JSON.sh format into given ARRAY. ARRAY name must be delared with "declare -A ARRAY" upfront,
usage: jssh_readDB "ARRAY" "filename"
example:
# read file data-bot-bash/somevalues.jssh into array SOMEVALUES
jssh_readDB "SOMEVALUES" "${DATADIR:-}/somevalues"
print "${SOMEVALUES[*]}"
jssh_writeDB
Write content of given ARRAY into jsshDB file. ARRAY name must be delared with "declare -A ARRAY" upfront, "DB" file MUST exist or nothing is written.
Note: Every existing content is overwritten.
usage: jssh_writeDB "ARRAY" "filename"
example:
declare -A MYVALUES
MYVALUES["value1"]="value1"
MYVALUES["loveit"]="value2"
MYVALUES["whynot"]="value3"
# create DB
jssh_newDB "${DATADIR:-}/myvalues"
# write to file data-bot-bash/somevalues.jssh from array MYVALUES
jssh_writeDB "MYVALUES" "${DATADIR:-}/myvalues"
# show whats written
DBfile="$(jssh_checkDB "${DATADIR:-}/myvalues.jssh")"
cat "DB$file"
["value1"] "value1"
["loveit"] "value2"
["whynot"] "value3"
jssh_updateDB
Update/write content of given ARRAY into a jsshDB file. ARRAY name must be delared with "declare -A ARRAY" upfront, "DB" file MUST exist or nothing is written.
Note: Existing DB content not in ARRAY is kept.
usage: jssh_updateDB "ARRAY" "filename"
example:
# continued example from writeDB
MYVALUES=()
MYVALUES["newvalue"]="this is new"
# update file data-bot-bash/somevalues.jssh from array MYVALUES
jssh_updateDB "MYVALUES" "${DATADIR:-}/myvalues"
# show whats written
["value1"] "value1"
["loveit"] "value2"
["whynot"] "value3"
["newvalue"] "this is new"
# now writeDB
cat "$DBfile"
jssh_writeDB "MYVALUES" "${DATADIR:-}/myvalues"
# show whats written, ups!
cat "$DBfile"
["newvalue"] "this is new"
jssh_insertDB
Insert, update, append a key=value pair to a jsshDB file, key name is only allowed to contain '-a-zA-Z0-9,._'
usage: jssh_insertDB "key" "value" "filename"
example:
jssh_insertDB "newkey" "an other value" "${DATADIR:-}/myvalues"
jssh_getDB
Read a key=value pair from a jsshDB file, key name is only allowed to contain '-a-zA-Z0-9,._'
usage: jssh_getDB "key" "filename"
example:
result="$(jssh_getDB "newvalue" "${DATADIR:-}/myvalues")"
# lets see whats the value of key newvalue
echo "$result"
this is new
