Changelog 2021.10.28.dev1

Oct 28, 2021 • Anders Berkeman, Carl Drougge, and Sofia Hörberg

Highlights

• new intro command to help you get started.
• examples:
  • use ax init --examples to get examples of simple methods in your new project.
• shell commands can output csv or json from a dataset.

ax grep

• new --format= / -f argument that accepts
  • text (the old default)
  • csv (the new default, similar to text but with quoting when needed)
  • json
• coloured matches are now the default if output is a tty, --colour argument now works similarly to gnu grep (auto / never / always).

Build

• new force_build flag, available as an argument on build() calls and also as “ax run --flags force_build” (to force build everything in that script).

Datasets

• better error messages for many problems in writers.
• Dataset.min(colname) and .max(colname) to match the API on DatasetChain (including giving None for non-existant columns).

Shell

• new intro command to help you get started.
• init can include --examples in the new project.
• script command takes --path / -p argument.
• run command changes --fullpath / -F to --full-path / -p for consistency.
• workdir command takes --full-path / -p argument.
• all commands should now only use colour when output is a tty, or as specified with the env vars NO_COLOR, CLICOLOR and CLICOLOR_FORCE.

And finally

• more tests.
• various bug fixes / minor improvements of course.

Note: Python 2 is still supported, but will likely be unsupported soon.
