# A development swiss army knife script. The goals are to:
#
#  - encode some best practices and hard-won knowledge of quirks and corners of
#    our tooling
#  - simplify development; especially for new-comers; instead of writing a huge
#    document describing how to do various dev tasks (or worse yet, not writing
#    one), make it runnable
#
# This makes use of 'cabal.project.dev-sh*' files when building. See
# 'cabal.project.dev-sh.local'.
#
# The configuration for the containers of each backend is stored in
# separate files, see files in 'scripts/containers'

A swiss-army script for local graphql-engine development

Usage:   $0 <COMMAND>

Available COMMANDs:

  graphql-engine
    Launch graphql-engine, connecting to a database launched with
    '$0 postgres'.

  postgres
    Launch a postgres container suitable for use with graphql-engine, watch its
    logs, clean up nicely after

  mssql
    Launch a MSSQL container suitable for use with graphql-engine, watch its
    logs, clean up nicely after

  citus
    Launch a Citus single-node container suitable for use with graphql-engine,
    watch its logs, clean up nicely after

  mysql
    Launch a MySQL container suitable for use with graphql-engine, watch its
    logs, clean up nicely after

  test [--integration [pytest_args...] | --unit | --hlint]
    Run the unit and integration tests, handling spinning up all dependencies.
    This will force a recompile. A combined code coverage report will be
    generated for all test suites.
    Either integration or unit tests can be run individually with their
    respective flags. With '--integration' any arguments that follow will be
    passed to the pytest invocation. Run the hlint code linter individually
    using '--hlint'.

    For unit tests, you can limit the number of tests by using
    'test --unit --match "runTx" mssql'
