# Description Fixes: #12795 The issue is caused by an empty position of `ParseError::UnexpectedEof`. So no detailed message is displayed. To fix the issue, I adjust the start of span to `span.end - 1`. In this way, we can make sure that it never points to an empty position. After lexing item, I also reorder the unclosed character checking . Now it will be checking unclosed opening delimiters first. # User-Facing Changes After this pr, it outputs detailed error message for incomplete string when running scripts. ## Before ``` ❯ nu -c "'ab" Error: nu::parser::unexpected_eof × Unexpected end of code. ╭─[source:1:4] 1 │ 'ab ╰──── > ./target/debug/nu -c "r#'ab" Error: nu::parser::unexpected_eof × Unexpected end of code. ╭─[source:1:6] 1 │ r#'ab ╰──── ``` ## After ``` > nu -c "'ab" Error: nu::parser::unexpected_eof × Unexpected end of code. ╭─[source:1:3] 1 │ 'ab · ┬ · ╰── expected closing ' ╰──── > ./target/debug/nu -c "r#'ab" Error: nu::parser::unexpected_eof × Unexpected end of code. ╭─[source:1:5] 1 │ r#'ab · ┬ · ╰── expected closing '# ╰──── ``` # Tests + Formatting Added some tests for incomplete string. --------- Co-authored-by: Ian Manske <ian.manske@pm.me>
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.
