# Description Added a few syntax errors in ints and strings, changed parser to stop and show that error rather than continue trying to parse those tokens as some other shape. However, I don't see how to push this direction much further, and most of the classic confusing errors can't be changed. Flagged as WIP for the moment, but passes all checks and works better than current release: 1. I have yet to figure out how to make these errors refer back to the book, as I see some other errors do. 2. How to give syntax error when malformed int is first token in line? Currently parsed as external command, user gets confusing error message. 3. Would like to be more strict with *decimal* int literals (lacking, e.g, `0x' prefix). Need to tinker more with the order of parse shape calls, currently, float is tried after int, so '1.4' has to be passed. _(Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience.)_ ```bash 〉"\z" Error: ╭─[entry #3:1:1] 1 │ "\z" · ─┬─ · ╰── Syntax error in string, unrecognized character after escape '\'. ╰──── ``` Canonic presentation of a syntax error. ```bash 〉" \u{01ffbogus}" Error: × Invalid syntax ╭─[entry #2:1:1] 1 │ " \u{01ffbogus}" · ───────┬────── · ╰── Syntax error in string, expecting 1 to 6 hex digits in unicode escape '\u{X...}', max value 10FFFF. ╰──── ``` Malformed unicode escape in string, flagged as error. String parse can be opinionated, it's the last shape tried. ```bash 〉0x22bogus Error: nu:🐚:external_command (link) × External command failed ╭─[entry #4:1:1] 1 │ 0x22bogus · ────┬──── · ╰── executable was not found ╰──── help: No such file or directory (os error 2) ``` A *correct* number in first token would be evaluated, but an *incorrect* one is treated as external command? Confusing to users. ```bash 〉0 + 0x22bogus Error: × Invalid syntax ╭─[entry #5:1:1] 1 │ 0 + 0x22bogus · ────┬──── · ╰── Syntax error in int, invalid digits in radix 16 int. ╰──── ``` Can give syntax error if token is unambiguously int literal. e.g has 0b or 0x prefix, could not be a float. ```bash 〉0 + 098bogus Error: nu::parser::unsupported_operation (link) × Types mismatched for operation. ╭─[entry #6:1:1] 1 │ 0 + 098bogus · ┬ ┬ ────┬─── · │ │ ╰── string · │ ╰── doesn't support these values. · ╰── int ╰──── help: Change int or string to be the right types and try again. ``` But *decimal* literal (no prefix) can't be too strict. Parser is going to try float later. So '1.4' must be passed. # User-Facing Changes First and foremost, more specific error messages for typos in string and int literals. Probably improves interactive user experience. But a script that was causing and then checking for specific error might notice a different error message. _(List of all changes that impact the user experience here. This helps us keep track of breaking changes.)_ # Tests + Formatting Added (positive and negative unit tests in `cargo test -p nu-parser`. Didn't add integration tests. Make sure you've run and fixed any issues with these commands: - [x] `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - [x] `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary.

…11569) # Description Fixes: #11455 ### For arguments which is annotated with `:path/:directory/:glob` To fix the issue, we need to have a way to know if a path is originally quoted during runtime. So the information needed to be added at several levels: * parse time (from user input to expression) We need to add quoted information into `Expr::Filepath`, `Expr::Directory`, `Expr::GlobPattern` * eval time When convert from `Expr::Filepath`, `Expr::Directory`, `Expr::GlobPattern` to `Value::String` during runtime, we won't auto expanded the path if it's quoted ### For `ls` It's really special, because it accepts a `String` as a pattern, and it generates `glob` expression inside the command itself. So the idea behind the change is introducing a special SyntaxShape to ls: `SyntaxShape::LsGlobPattern`. So we can track if the pattern is originally quoted easier, and we don't auto expand the path either. Then when constructing a glob pattern inside ls, we check if input pattern is quoted, if so: we escape the input pattern, so we can run `ls a[123]b`, because it's already escaped. Finally, to accomplish the checking process, we also need to introduce a new value type called `Value::QuotedString` to differ from `Value::String`, it's used to generate an enum called `NuPath`, which is finally used in `ls` function. `ls` learned from `NuPath` to know if user input is quoted. # User-Facing Changes Actually it contains several changes ### For arguments which is annotated with `:path/:directory/:glob` #### Before ```nushell > def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a > def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a > def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a ``` #### After ```nushell > def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a > def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a > def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a ``` ### For ls command `touch '[uwu]'` #### Before ``` ❯ ls -D "[uwu]" Error: × No matches found for [uwu] ╭─[entry #6:1:1] 1 │ ls -D "[uwu]" · ───┬─── · ╰── Pattern, file or folder not found ╰──── help: no matches found ``` #### After ``` ❯ ls -D "[uwu]" ╭───┬───────┬──────┬──────┬──────────╮ │ # │ name │ type │ size │ modified │ ├───┼───────┼──────┼──────┼──────────┤ │ 0 │ [uwu] │ file │ 0 B │ now │ ╰───┴───────┴──────┴──────┴──────────╯ ``` # Tests + Formatting Done # After Submitting NaN

# Description After this pr, nushell is able to raise errors with a backtrace, which should make users easier to debug. To enable the feature, users need to set env variable via `$env.NU_BACKTRACE = 1`. But yeah it might not work perfectly, there are some corner cases which might not be handled. I think it should close #13379 in another way. ### About the change The implementation mostly contained with 2 parts: 1. introduce a new `ChainedError` struct as well as a new `ShellError::ChainedError` variant. If `eval_instruction` returned an error, it converts the error to `ShellError::ChainedError`. `ChainedError` struct is responsable to display errors properly. It needs to handle the following 2 cases: - if we run a function which runs `error make` internally, it needs to display the error itself along with caller span. - if we run a `error make` directly, or some commands directly returns an error, we just want nushell raise an error about `error make`. 2. Attach caller spans to `ListStream` and `ByteStream`, because they are lazy streams, and *only* contains the span that runs it directly(like `^false`, for example), so nushell needs to add all caller spans to the stream. For example: in `def a [] { ^false }; def b [] { a; 33 }; b`, when we run `b`, which runs `a`, which runs `^false`, the `ByteStream` only contains the span of `^false`, we need to make it contains the span of `a`, so nushell is able to get all spans if something bad happened. This behavior is happened after running `Instruction::Call`, if it returns a `ByteStream` and `ListStream`, it will call `push_caller_span` method to attach call spans. # User-Facing Changes It's better to demostrate how it works by examples, given the following definition: ```nushell > $env.NU_BACKTRACE = 1 > def a [x] { if $x == 3 { error make {msg: 'a custom error'}}} > def a_2 [x] { if $x == 3 { ^false } else { $x } } > def a_3 [x] { if $x == 3 { [1 2 3] | each {error make {msg: 'a custom error inside list stream'} } } } > def b [--list-stream --external] { if $external == true { # error with non-zero exit code, which is generated from external command. a_2 1; a_2 3; a_2 2 } else if $list_stream == true { # error generated by list-stream a_3 1; a_3 3; a_3 2 } else { # error generated by command directly a 1; a 2; a 3 } } ``` Run `b` directly shows the following error: <details> ```nushell Error: chained_error × oops ╭─[entry #27:1:1] 1 │ b · ┬ · ╰── error happened when running this ╰──── Error: chained_error × oops ╭─[entry #26:10:19] 9 │ # error generated by command directly 10 │ a 1; a 2; a 3 · ┬ · ╰── error happened when running this 11 │ } ╰──── Error: × a custom error ╭─[entry #6:1:26] 1 │ def a [x] { if $x == 3 { error make {msg: 'a custom error'}}} · ─────┬──── · ╰── originates from here ╰──── ``` </details> Run `b --list-stream` shows the following error <details> ```nushell Error: chained_error × oops ╭─[entry #28:1:1] 1 │ b --list-stream · ┬ · ╰── error happened when running this ╰──── Error: nu:🐚:eval_block_with_input × Eval block failed with pipeline input ╭─[entry #26:7:16] 6 │ # error generated by list-stream 7 │ a_3 1; a_3 3; a_3 2 · ─┬─ · ╰── source value 8 │ } else { ╰──── Error: nu:🐚:eval_block_with_input × Eval block failed with pipeline input ╭─[entry #23:1:29] 1 │ def a_3 [x] { if $x == 3 { [1 2 3] | each {error make {msg: 'a custom error inside list stream'} } } } · ┬ · ╰── source value ╰──── Error: × a custom error inside list stream ╭─[entry #23:1:44] 1 │ def a_3 [x] { if $x == 3 { [1 2 3] | each {error make {msg: 'a custom error inside list stream'} } } } · ─────┬──── · ╰── originates from here ╰──── ``` </details> Run `b --external` shows the following error: <details> ```nushell Error: chained_error × oops ╭─[entry #29:1:1] 1 │ b --external · ┬ · ╰── error happened when running this ╰──── Error: nu:🐚:eval_block_with_input × Eval block failed with pipeline input ╭─[entry #26:4:16] 3 │ # error with non-zero exit code, which is generated from external command. 4 │ a_2 1; a_2 3; a_2 2 · ─┬─ · ╰── source value 5 │ } else if $list_stream == true { ╰──── Error: nu:🐚:non_zero_exit_code × External command had a non-zero exit code ╭─[entry #7:1:29] 1 │ def a_2 [x] { if $x == 3 { ^false } else { $x } } · ──┬── · ╰── exited with code 1 ╰──── ``` </details> It also added a message to guide the usage of NU_BACKTRACE, see the last line in the following example: ```shell ls asdfasd Error: nu:🐚:io::not_found × I/O error ╰─▶ × Entity not found ╭─[entry #17:1:4] 1 │ ls asdfasd · ───┬─── · ╰── Entity not found ╰──── help: The error occurred at '/home/windsoilder/projects/nushell/asdfasd' set the `NU_BACKTRACE=1` environment variable to display a backtrace. ``` # Tests + Formatting Added some tests for the behavior. # After Submitting

This PR adds the `toolkit run pr` and `toolkit download pr` commands to `toolkit`. This is a more fleshed out version of the snippet shared in #16633, with robust error handling and cross-platform unzip support. When using `toolkit run pr`, the script will also check if the most recent binary for that PR has already been downloaded, and if so it will run that instead. I tried to make the error reporting as good as a built-in command to see how difficult that would be, and with use of the `--head: oneof<>` trick, it turned out pretty good. With access to the call span, the workflow is very similar to when writing a built-in command. I also used a `Spanned`-like record, which helped as well. ```nushell toolkit run pr 16740 # => Error: nu::shell::error # => # => × Command not found # => ╭─[entry #4:1:26] # => 1 │ overlay use -pr toolkit; toolkit run pr 16740 # => · ───────┬────── # => · ╰── requires `gh` # => ╰──── # => help: Please install the `gh` commandline tool ``` <details> <summary>More error reporting notes</summary> In an earlier version of the script, `run pr` called `download pr` directly. I ended up changing the way this worked so that `run pr` could use the workflow_id. Here's a couple snippets I thought were neat from this older version. **Passing span via `--head`:** ```nushell def download [--head: oneof<>] { let span = $head | default (metadata $head).span error make {msg: "a", label: {text: here, span: $span}} } def run [--head: oneof<>] { let span = (metadata $head).span download --head=$span } download # => Error: nu:🐚:error # => # => × a # => ╭─[entry #6:1:1] # => 1 │ download # => · ────┬─── # => · ╰── here # => ╰──── run # => Error: nu:🐚:error # => # => × a # => ╭─[entry #7:1:1] # => 1 │ run # => · ─┬─ # => · ╰── here # => ╰──── ``` **Using "spanned" number as CLI parameter and as internal caller parameter** ```nushell def download [number: oneof<int, record<item: int, span: record>>] { let number = match $number { {item: $_, span: $_} => $number, $val => {item: $number, span: (metadata $number).span} } error make {msg: "a", label: {text: here, span: $number.span}} } def run [number: int] { let number = {item: $number, span: (metadata $number).span} download $number } download 123 # => Error: nu:🐚:error # => # => × a # => ╭─[entry #9:1:10] # => 1 │ download 123 # => · ─┬─ # => · ╰── here # => ╰──── run 123 # => Error: nu:🐚:error # => # => × a # => ╭─[entry #10:1:5] # => 1 │ run 123 # => · ─┬─ # => · ╰── here # => ╰──── ``` </details> ## Release notes summary - What our users need to know The toolkit in the Nushell repository can now download and run PRs by downloading artifacts from CI runs. It can be run like this: ```nushell use toolkit toolkit run pr <number> ```
