# Nushell core team meeting 2024-08-07 ## Attendees - Devyn - Andy - Michael - Stefan - Darren - Jack - Antoine - Rose ## Agenda - [x] Material for demo - [x] Whether to or not to merge `polars sink` and `polars to-` into one `polars save` command - [x] Do we want to ship the assignment change in one release? (backtick string behavior, impact on existing scripts) ## Discussed Topics ### Stefan's demo - Send him some quick oneliners that are really impressive for a demo - Ask Sophia? - Look at Reilly's demo - The wayback machine [1st reedline video](https://web.archive.org/web/20230525192434/https://www.youtube.com/watch?v=xXVyHsRR168) ### Polars - `polars sink` is a new command that uses the streaming stuff to stream directly to disk from a lazyframe - actually maybe we want `polars save` instead? unify the `polars to-` whatever with sink? - automatically handle lazyframes - don't need to stay true to the polars API - options for different data formats? - key/value or use actual nushell options? - the actual nushell options are self-documenting so that's nice - doing stuff more lazily when possible - Would like to have more nushell-like apis for some things ### Plugins as modules - Would be nice to be able to rename plugins entirely e.g. `plugin use polars as pl` - having them be modules would work - Modules currently interact weirdly with the help system, gwenya has done some work on this but there's probably more to be done ### assignment with backticks - This could be a major gotcha - ``` $foo = `bar` ``` now behaving quite differently - We might not want backticks to work this way - Maybe force people to use the carets to run an external command with spaces special character - how relevant is the backtick string - acts like a bare word - execute in command position otherwise acts like a string - Does not apply `\` escaping (so escape hatch for windows paths vs. `""` strings) - could this be just a regular string type without escaping `''` and for execution you require `^` (our internal command handle the spaces for subcommands anyways so no need for quoting there.) - have completion add the `^` when necessary, in command position - globs: this works right now: ``` ls `*.txt` ``` - maybe backtick quotes doing (glob) expansion (while permitting whitespace) is still good ### effect of the assignment change ``` $env.EDITOR = vim ``` would now execute instead of assign (:wq) Unlikely to be totally destructive but annoying to mitigate if in configs or scripts If we want to do a warning phase it would only catch the most actively updating users. Solution: just require a caret for external in assignment RHS for a few releases, so the impact is mitigated and at some point we can sunset the caret requirement.
