# Nushell core team meeting 2022-10-19 ## Attendees - Jakub - JT - Darren - Michael - Andres ## Agenda - JT's experiment - Fish style abbreviations as an alternative to aliases? - `++` as a concat operator? - Systematic semantics effort - Several PRs that need to be looked at/landed/rejected - [input types/output types pr 6796](https://github.com/nushell/nushell/pull/6796) - actionable meetings? # Discussed Topics ## PRs 6655 - Need to help them get if over the line 6701 - core-team chat about tar PR offline 6752 - wait for reply to Kubouch's question in the issue, change the error 'command foo is not found but exists in module span' and a note that says, 'replace fixme something blah' - JT fix these notes please. Include a note with 'spam foo' suggestion. 6766 - ++ append lists, ship it after questions resolved 6781 - depends on a reedline counterpart, darren is working with nibon to finalize requirements then we can land 6786 - domterm - shouldn't special case specific terminals in the shell. someone needs to respond and close the issue. storm will comment on the pr. 6790 - dan davison, land it after 70.1 6791 - need to look up signal-hook crate, is it doing the coredump or is it just notifying the user of that specific signal. 6793 - jt thinks this design may be error prone, assume we'll accept it. ultimately we want a better design for output 6798 - skip for jt's solution tbd should reject this pr 6799 - maybe check the right bit, reject this pr, point them to the umask or metadata that ls is using for pointers 6801 - hold on it due to 6801 6802 - 498 in reedline, land these two of dan's in reedline and nushell for testing for the next couple weeks. 6809 - not safe to do - jt's comments in the PR 6796 - like the direction, keep encouraging him to go forward with this ## Fish abbr JT watched a video of a person who was an advanced fish user that used abbr and was blown away. "I want that!" abbr wouldn't work in scripts like aliases do aliases are helpful for work-around commands if you have a name collision Question: Are aliases used in scripts? (One use case: virtualenv) ## JT's experiment jt applying lessons learned from pest and tree-sitter experiments. error recovery, written in rust. Essentially a new parser and lexer based on these learnings.
