# Description In #10232, the allowed input types were changed to be stricter, only allowing records with types that can easily map onto sqlite equivalents. Unfortunately, null was left out of the accepted input types, which makes inserting rows with null values impossible. This change fixes that by accepting null values as input. One caveat of this is that when the command is creating a new table, it uses the first row to infer an appropriate sqlite schema. If the first row contains a null value, then it is impossible to tell which type this column is supposed to have. Throwing a hard error seems undesirable from a UX perspective, but guessing can lead to a potentially useless database if we guess wrong. So as a compromise, for null columns, we will assume the sqlite type is TEXT and print a warning so the user knows. For the time being, if users can't avoid a first row with null values, but also wants the right schema, they are advised to create their table before running `into sqlite`. A future PR can add the ability to explicitly specify a schema. Fixes #12225 # Tests + Formatting * Tests added to cover expected behavior around insertion of null values
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
