OneTick database viewer

onetick-ext-view

Onetick View is a terminal UI for browsing Onetick databases.

It is based on onetick-py library and can work in two modes: localy-installed mode and WebAPI mode. The mode depends on the set environment variables and installed onetick python api libraries. See onetick-py documentation for details: https://docs.pip.distribution.sol.onetick.com/static/installation/webapi.html.

In order to use WebAPI mode install package with webapi extra:

pip install onetick-ext-view[webapi]

Usage (WebAPI mode):

# set env variables:
OTP_HTTP_ADDRESS='https://rest.cloud.onetick.com'
OTP_ACCESS_TOKEN_URL='https://cloud-auth.parent.onetick.com/realms/OMD/protocol/openid-connect/token'
OTP_CLIENT_ID='?????????????'
OTP_CLIENT_SECRET='?????????'

onetick view                                           # (get remote databases from WebAPI server)

Usage (locally-installed mode):

# set env variables:
MAIN_ONE_TICK_DIR="/opt/one_market_data/one_tick"

onetick view                                           # (scan current working dir)
onetick view /tmp                                      # (i.e. for tests with --keep-generated=always)
onetick view --remote-ts remote.example.com:40001      # (connect to remote server)
onetick view /tmp --remote-ts remote.example.com:40001 # (both scan specific directory and connect to remote server)
