version

Bashbot Example - Get Version

In this example, a bash script is executed, attempting three methods of returning the currently running version of Bashbot.

Bashbot configuration

This command is triggered by sending bashbot version in a slack channel where Bashbot is also a member. The script is expected to exist before execution at the relative path ./examples/version/get-version.sh and requires no additional input to execute. It takes no arguments/parameters and returns stdout as a slack message, in the channel it was executed from.

Bashbot script

The get-version.sh first checks to see if Bashbot is already available via $PATH and prints that version, if possible. Next, if the binary is being run from the ./bin directory, this script will grab the correct os/architecture from uname and attempt to print that version. If both of those methods fail, a Makefile target (go-version) is executed, provided the Makefile and go source exists. If all of those methods are unsuccessful, an error message is returned to slack that the version could not be determined.

Note: exit 0 is used in success/failure states to ensure error messages are returned to slack. If exit 1 is used for error states, a generic error message is returned to slack and stderr is suppressed.

# First check if bashbot is installed and pull that version
if command -v bashbot > /dev/null; then 
    command -v bashbot
    bashbot version
    exit 0
fi

# Next check if ./bin/bashbot-${os}-${arch} exists and pull that version
arch=amd64
[ "$(uname -m)" == "aarch64" ] && arch=arm64
os=$(uname | tr '[:upper:]' '[:lower:]')
if [ -f "./bin/bashbot-${os}-${arch}" ]; then
    echo "./bin/bashbot-${os}-${arch} version"
    ./bin/bashbot-${os}-${arch} version
    exit 0
fi

# Finally, check if bashbot go source exists and pull that version
go_filename=cmd/bashbot/bashbot.go
if [[ -f "./${go_filename}" ]] && [[ -f "./Makefile" ]]; then
    make go-setup
    make go-version
    exit 0
fi

echo "Could not determine the current version of bashbot"
exit 0
