# Description This PR makes it so that non-zero exit codes and termination by signal are treated as a normal `ShellError`. Currently, these are silent errors. That is, if an external command fails, then it's code block is aborted, but the parent block can sometimes continue execution. E.g., see #8569 and this example: ```nushell [1 2] | each { ^false } ``` Before this would give: ``` ╭───┬──╮ │ 0 │ │ │ 1 │ │ ╰───┴──╯ ``` Now, this shows an error: ``` Error: nu:🐚:eval_block_with_input × Eval block failed with pipeline input ╭─[entry #1:1:2] 1 │ [1 2] | each { ^false } · ┬ · ╰── source value ╰──── Error: nu:🐚:non_zero_exit_code × External command had a non-zero exit code ╭─[entry #1:1:17] 1 │ [1 2] | each { ^false } · ──┬── · ╰── exited with code 1 ╰──── ``` This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This PR also partially addresses #10633 and #10624 (only the last command of a pipeline is currently checked). It looks like #8569 is already fixed, but this PR will make sure it is definitely fixed (fixes #8569). # User-Facing Changes - Non-zero exit codes and termination by signal now cause an error to be thrown. - The error record value passed to a `catch` block may now have an `exit_code` column containing the integer exit code if the error was due to an external command. - Adds new config values, `display_errors.exit_code` and `display_errors.termination_signal`, which determine whether an error message should be printed in the respective error cases. For non-interactive sessions, these are set to `true`, and for interactive sessions `display_errors.exit_code` is false (via the default config). # Tests Added a few tests. # After Submitting - Update docs and book. - Future work: - Error if other external commands besides the last in a pipeline exit with a non-zero exit code. Then, deprecate `do -c` since this will be the default behavior everywhere. - Add a better mechanism for exit codes and deprecate `$env.LAST_EXIT_CODE` (it's buggy). |

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.
