## title:         remote_deploy.sh
## description:   A dev script for deploying & compiling the `ZeroMQ Server` script and its dependencies from a
##                local dev environment into a remote MetaTrader 4 instance via SSH.
## precondition:  Deployment target is a Windows 10 instance which has MT4 (32-bit) installed, and
##                WSL (Windows Subsystem for Linux) installed which is running a SSH server. The client machine running
##                this script should have SSH master connections enabled to prevent excessive handshakes.
## postcondition: MetaTrader 4 will have the latest server script and should be restarted to apply it
##                (see restart_mt4.bat).
##
## configurable variables:
## ----------------------------------------------------------------------------

# the server script filename
SCRIPT_FILENAME='ZeroMQ_Server.mq4'

# the SSH endpoint of the deployment target
SSH_ENDPOINT='joe@win10'

# the remote MT4 profile location
MT4_PROFILE='C:\Users\Joe\AppData\Roaming\MetaQuotes\Terminal\B4465D2178C9DCD8E8CD3CCFEA8AA766'

# the remote MT4 install location
