Nushell 0.112.1

Today, we're releasing version 0.112.1 of Nu. This release adds structured markdown parsing with from md, a new % sigil to explicitly call internal commands, and a bunch of new config options to better shape Nu to your workflow, along with improvements to type checking for cell paths.

Note

Some crates failed to release properly, so we skip 0.112.0.

Where to get it

Nu 0.112.1 is available as pre-built binaries or from crates.io. If you have Rust installed you can install it using cargo install nu.

As part of this release, we also publish a set of optional plugins you can install and use with Nushell.

Highlights and themes of this release [toc]

Parse markdown via `from md`

Breaking change

The from md is considered a breaking change as previously open *.md would return a string.

We added a new from md command that lets you parse markdown into structured data. Instead of manually pulling pieces out of a markdown string and hoping it works, you now get something much more reliable to work with.

Info

Since from commands affect how open behaves, we'd love your input on whether the name still makes sense. Join the discussion on Github and share your thoughts.

Check out the example output here.

No more shadows, call internals with `%`

Nushell already has the ^ sigil to explicitly call external commands. That way you can still run a binary even if there's a built-in or custom command with the same name.

A lot of people asked for something similar for internal commands and now we have it. Thanks to @fdncred, the new % sigil lets you explicitly call built-ins.

It always uses the initial scope and won't fall back to externals. That means you can reliably call internal commands, even if they're hidden.

Configure Nushell how you like

This release comes with a bunch of new config options to tweak things to your liking.

`$env.config.history.path`

# history.path (string): Path to the history file.
# If not set, Nushell will use the default location.
# You can also provide a custom path for your history file.
# Examples:
# Use a custom location (e.g., in your home directory):
$env.config.history.path = "~/custom/my-history.txt"
# Default behavior:
# If not set (null), Nushell stores history in the default config directory.
# If set to a directory, the appropriate file name (e.g., history.txt) is used.
# If set to a filename only, the file will be stored in $nu.default-config-dir.

Thanks to @kx0101, you can now choose exactly where your history file lives. This ignores the file format, so make sure your config matches. You can also set it to null to disable history entirely. Read more.

`$env.config.history.ignore_space_prefixed`

# history.ignore_space_prefixed (bool): Whether commands starting with leading whitespace are saved to history.
# true: Commands starting with one or more spaces or tabs will NOT be saved.
# false: All commands are saved, including those with any amount of leading whitespace.
# Default: true
$env.config.history.ignore_space_prefixed = true

@guluo2016 added an option to control whether commands starting with a space end up in your history. Read more.

`$env.config.auto_cd_implicit`

# auto_cd_implicit (bool): Gives precedence to auto-cd when command string is
# an existing directory path.
# false: A relative (e.g.  './dirname') or absolute path is required to auto-cd.
# true: If the command string matches a subdirectory in the current directory
# (e.g. 'src'), auto-cd will be triggered without needing './' or '/'.
$env.config.auto_cd_implicit = false

@dxrcy added a config option that lets you automatically cd into directories when you type their name. Read more.

`$env.config.hinter.closure`

# hinter.closure (closure|null): Custom hint closure.
# Closure input: one record argument {|ctx| ... } where
#   $ctx.line (string): current line buffer
#   $ctx.pos (int): current cursor position
#   $ctx.cwd (string): current working directory
# Return:
#   string -> hint suffix to render and accept
#   record -> {hint: string, next_token?: string} for custom token splitting
#   null   -> no hint (equivalent to "")
# Any closure error or unsupported return type yields no hint.
# To use the built-in hinter instead, set hinter.closure = null in config.
# This closure runs frequently while typing, so keep it lightweight.
# Default: null
$env.config.hinter.closure = null

# Example:
# $env.config.hinter.closure = {|ctx|
#   let last = (history | last 1 | get command_line? | get 0?)
#   if $last == null or not ($last | str starts-with $ctx.line) {
#     null
#   } else {
#     ($last | str substring ($ctx.line | str length)..)
#   }
# }

Thanks to @stuartcarnie, you can now plug in your own hinter using a closure. Read more.

`$env.config.table.mode = "frameless"`

# table.mode (string): Visual border style for tables.
# One of: "rounded", "basic", "compact", "compact_double", "light", "thin",
# "with_love", "reinforced", "heavy", "none", "psql", "markdown", "dots",
# "restructured", "ascii_rounded", "basic_compact", "single", "double",
# "frameless".
# Can be overridden with `| table --theme/-t`.
# Default: "rounded"
$env.config.table.mode = "rounded"

@Benjas333 added a new table style called "frameless". Take a look here.

`$env.config.color_config.binary_*`

# color_config.binary_null_char: Style for null characters (\0) in binary hex viewer.
# Default: grey42
$env.config.color_config.binary_null_char = "grey42"

# color_config.binary_printable: Style for printable ASCII characters in binary hex viewer.
# Default: cyan_bold
$env.config.color_config.binary_printable = "cyan_bold"

# color_config.binary_whitespace: Style for whitespace ASCII characters in binary hex viewer.
# Default: green_bold
$env.config.color_config.binary_whitespace = "green_bold"

# color_config.binary_ascii_other: Style for other ASCII characters in binary hex viewer.
# Default: purple_bold
$env.config.color_config.binary_ascii_other = "purple_bold"

# color_config.binary_non_ascii: Style for non-ASCII characters in binary hex viewer.
# Default: yellow_bold
$env.config.color_config.binary_non_ascii = "yellow_bold"

@ian-h-chamberlain added more color options for binary data in the hex viewer in #17887.

Types via cell.paths! - `cell-path-types`

Experimental option

This feature is behind an experimental option. Run Nushell with --experimental-option=cell-path-types or set before running Nushell the environment variable to NU_EXPERIMENTAL_OPTIONS=cell-path-types.

@blindFS introduced a new experimental option that makes type inference smarter when working with cell paths.

Before this, issues with nested types would only show up at runtime. Now they can already be caught during parsing.

Check out some examples here.

Parse markdown via `from md` [toc]
PR #17937 by @fdncred

Info

The introduction of from md caused some discussion whether Nushell should automatically parse text formats like markdown. We want to encourage discussion whether this is a fitting name or not in a Github discussion. Please state your opinion on this.

Added new command from md to parse markdown into an AST. This is considered a breaking change as opening a markdown file now no longer returns a raw string but rather a structured AST.

Use open --raw to open without conversion or hide the command using hide 'from md'.

Other breaking changes [toc]

Mutable cell assignment now respects experimental option reorder-cell-paths. (#17696)
job tag is now called job describe, the --tag flag in job spawn and the tag column in job list, as tag was renamed to description for these. (#17496)
random choice from std-rfc now behaves more similar to first, so that random choice returns a single element and random choice 1 returns a list with one element. (#17983)

New command `str escape-regex` [toc]
PR #17703 by @Juhan280

A new command, str escape-regex, has been added. It allows us to sanitize strings before inserting them into a regular-expression pattern.

# Check if the input matches the data exactly (not using `==` for demonstration)

# User input used directly in a regex
def bad [str: string] {
  $in like $"^($str)$"
}

"hello" | bad ".*"   # true (incorrect)

# Escape the input before inserting it into the regex
def good [str: string] {
  $in like $"^($str | str escape-regex)$"
}

"hello" | good ".*"  # false

    "bar": [123, 456],
    "baz": [2.0, 5.5],
    "zap": [false, true],
}

History file path can now be configured [toc]
PR #17425 by @kx0101

Nushell now supports configuring the history file path using $env.config.history.path. This value can be null or any custom location, which is particularly useful for TTY login scenarios where the --no-history flag cannot be used.

$env.config.history.path = null  # disable history
$env.config.history.path = "/custom/history.txt"  # custom location

New experimental option `cell-path-types` [toc]

Experimental option

Added a new experimental option named cell-path-types which enforces type inferencing on cell path expressions like {foo: 1}.foo if enabled. That means the following examples (previously caused runtime errors or ran successfully) will be rejected by the parser:

Added testbin "bins" to nushell help [toc]
PR #17728 by @fdncred

Updates the nushell command help by adding the testbin "bins" to the nu --help screen. Now you see this output in the --testbin section of the help.

  --testbin <string>
      run an internal test binary (see available bins below)
      Example: nu --testbin cococo
      Available test bins:
      chop -> With no parameters, will chop a character off the end of each line
      cococo -> Cross platform echo using println!()(e.g: nu --testbin cococo a b c)
      echo_env -> Echo's value of env keys from args(e.g: nu --testbin echo_env FOO BAR)
      echo_env_mixed -> Mix echo of env keys from input(e.g: nu --testbin echo_env_mixed out-err FOO BAR; nu --testbin echo_env_mixed err-out FOO BAR)
      echo_env_stderr -> Echo's value of env keys from args to stderr(e.g: nu --testbin echo_env_stderr FOO BAR)
      echo_env_stderr_fail -> Echo's value of env keys from args to stderr, and exit with failure(e.g: nu --testbin echo_env_stderr_fail FOO BAR)
      fail -> Exits with failure code <c>, if not given, fail with code 1(e.g: nu --testbin fail 10)
      iecho -> Another type of echo that outputs a parameter per line, looping infinitely(e.g: nu --testbin iecho 3)
      input_bytes_length -> Prints the number of bytes received on stdin(e.g: 0x[deadbeef] | nu --testbin input_bytes_length)
      meow -> Cross platform cat (open a file, print the contents) using read_to_string and println!()(e.g: nu --testbin meow file.txt)
      meowb -> Cross platform cat (open a file, print the contents) using read() and write_all() / binary(e.g: nu --testbin meowb sample.db)
      nonu -> Cross platform echo but concats arguments without space and NO newline(e.g: nu --testbin nonu a b c)
      nu_repl -> Run a REPL with the given source lines, it must be called with `--testbin=nu_repl`, `--testbin nu_repl` will not work due to argument count logic
      relay -> Relays anything received on stdin to stdout(e.g: 0x[beef] | nu --testbin relay)
      repeat_bytes -> A version of repeater that can output binary data, even null bytes(e.g: nu --testbin repeat_bytes 003d9fbf 10)
      repeater -> Repeat a string or char N times(e.g: nu --testbin repeater a 5)

Added configurable external hinter closure [toc]
PR #17566 by @stuartcarnie

Added support for configurable external hinter closures via $env.config.hinter.closure. This allows users to provide a custom closure that receives the current line, cursor position, and working directory, and returns inline hint text (like fish-style autosuggestions). Closures can return a simple string or a record {hint: string, next_token?: string} for custom token-based hint acceptance.

Examples

Atuin-based hint closure

$env.config.line_editor.external.hinter = {
  enable: true
  closure: {|ctx|
    if ($ctx.line | str length) == 0 {
      null
    } else {
      let candidate = (try {
        ^atuin search --cwd $ctx.cwd --limit 1 --search-mode prefix --cmd-only $ctx.line
        | lines
        | first
      } catch {
        null
      })

      if $candidate == null or not ($candidate | str starts-with $ctx.line) {
        null
      } else {
        ($candidate | str substring (($ctx.line | str length))..)
      }
    }
  }
}

Simple deterministic test closure (good for validating script hinter behavior)

$env.config.line_editor.external.hinter = {
  enable: true
  closure: {|ctx|
    if ($ctx.line | str length) == 0 {
      null
    } else {
      let target = "zzhint from-script"
      if not ($target | str starts-with $ctx.line) {
        null
      } else {
        let remaining = ($target | str substring (($ctx.line | str length))..)
        if ($remaining | str length) == 0 { null } else { $remaining }
      }
    }
  }
}

New `--base` flag for `url parse` [toc]
PR #17833 by @smartcoder0777

url parse now supports an optional --base/-b flag to resolve relative URLs against a base URL (WHATWG-compatible). This makes it easier to normalize links from scraped pages while still returning the same structured URL record (scheme, host, path, query, fragment, and params).

MCP: Auto-promote long-running evaluations to background jobs [toc]
PR #17861 by @andrewgazelka

Evaluations that take longer than 10 seconds, or are cancelled by the client, are automatically promoted to background jobs instead of being discarded. Their results are delivered to job 0's mailbox, where they can be retrieved using job recv. These promoted jobs appear in job list with descriptions like mcp: <command>, and they can be terminated using job kill. The timeout for this behavior can be configured through the $env.NU_MCP_PROMOTE_AFTER setting.

New option to allow command with space prefixes to be recorded in history [toc]
PR #17350 by @guluo2016

Usually commands that start with a space are not recorded to the history. With $env.config.history.ignore_space_prefixed this can be changed.

MCP: Promoted jobs now return full output [toc]
PR #17989 by @andrewgazelka

When an MCP evaluation gets auto-promoted to a background job (after timeout or client cancellation), the mailbox payload was the potentially-truncated MCP response. If output exceeded NU_MCP_OUTPUT_LIMIT, job recv would return a dangling $history.N reference instead of the actual data — $history is only populated for non-promoted evals.

This PR introduces an EvalOutput struct that separates the MCP response (possibly truncated with a $history note) from the full output string. Promoted jobs now send full_output through the mailbox so job recv always returns complete, usable data.

Also fixes a pipefail issue where external commands that write to both stdout and stderr would re-raise non_zero_exit_code after process_pipeline had already captured the output — solved by calling ignore_error(true) on the child.

Some Polars upgrades [toc]
PR #17641 by @ayax79

Upgrades polars to 0.53.
Reimplemented polars pivot command to polars' updated pivot library. Introduced support for "element" type aggregates.
polars unpivot will now only work on LazyFrames. Eager dataframes will be converted to a LazyFrame.
Added flags --keep-nulls and --empty-as-null to polars concat.
Some improvements on list conversion from nushell to polars. Sub-lists should retain their type instead of being converted to type "object". Using NuDataFrame::try_from_value will convert a Value::List object directly and attempt use an appropriate DataType before falling back to "object".
Added additional selectors: polars selector not, polars selector matches, polars selector starts-with.

Additional changes [toc]

Type widening now flattens a bit more. (#17575)
keybindings list command is updated with new descriptions. CutFromStartLinewise / CutToEndLinewise now takes keep_line instead of value as its parameter for clarity. (#17859)

first and last preserve pipeline metadata (such as content_type and path_columns) for list, range, and list-stream input. content_type is still cleared when the output is only part of a binary value (for example a single byte as an integer or a truncated binary value). (#17875)
Fixed a crash (“known external name not found”) when an alias reused the same name as an extern used for completions (for example wrapping an external with default flags). (#17878)
Update help text for the --ide-* commands in the nu --help screen. (#17905)
detect type now preserves content_type metadata if it cannot detect the input value (#17906)
Some code that was already known to be invalid early-on, will now be highlighted as an error. (#17917)

When --allow-errors is used, http head no longer fails on non-2xx statuses and still exposes headers. (#17650)
skip command only removes content_type metadata if n > 0 and input is binary. (#17867)
reject command also removes the path from path_columns metadata when removing a column. (#17867)

Brought back missing `--log-*` flags for nushell [toc]
PR #17732 by @fdncred

Fixed the broken nushell executable logging flags.

Here's the new logging section.

Logging:
  --log-level <string>
      log level for diagnostic logs (error, warn, info, debug, trace). Off by default
      Example: nu --log-level info
  --log-target <string>
      set the target for the log to output. stdout, stderr(default), mixed or file (requires --log-file)
      Example: nu --log-target stdout
  --log-file <path>
      specify a custom log file path (requires --log-target file and --log-level <level>)
      Example: nu --log-target file --log-file ~/.local/share/nushell/nu.log --log-level info
  --log-include <string...>
      set the Rust module prefixes to include from the log output
      Example: nu --log-include info

      set the Rust module prefixes to exclude from the log output
      Example: nu --log-exclude info

Fix confusing type mismatch error in bytes collect [toc]
PR #17746 by @Bortlesboat

bytes collect now accepts table/stream input (e.g. from each), and type mismatch errors no longer repeat the same type multiple times.

Two changes:

Added Type::table() to bytes collect input types so pipelines like 0..128 | each {} | into binary --compact | bytes collect work without requiring an explicit collect first
Deduplicated types in combined_type_string so error messages say "binary, table, or record" instead of "binary, binary, binary, binary, table, or record"

built-in commands now support `null` for optional parameters [toc]
PR #17753 by @0xRozier

Optional positional parameters in built-in commands now accept null, treating it as if the argument was omitted. This allows custom commands to wrap built-ins and transparently forward optional parameters:

> def wraps-first [rows?: int] { [1, 2, 3] | first $rows }

finally block won't run twice if error produced in finally block [toc]

  × originates from here
   ╭─[repl_entry #6:3:3]

   ╰────

It prints "inside finally" once.

finally block won't run before try/catch finished

> try {
  nu -c 'print before; sleep 3sec; print after'
} finally {
  print "finally ran"
}
before
after
finally ran

Finally won't run before try finished.

Notes about streaming

try does not stream if catch or finally exists.
catch does not stream if finally exists.

let ignores pipefail checking

> nu -c "print 'hello\nworld'; exit 1" | lines | let x
╭───┬───────╮
│ 0 │ hello │
│ 1 │ world │
╰───┴───────╯
> $x
╭───┬───────╮
│ 0 │ hello │
│ 1 │ world │
╰───┴───────╯

The variable x will be assigned.

Try doesn't produce output if it has an error

> try { nu -c 'exit 1' | is-empty } catch { 'result-on-catch' }
result-on-catch

It returns result-on-catch, and redundant true won't be returned.

Other fixes [toc]

Fixed the problem where searching in the explore command was off by 1 which caused the hit to sometimes be hidden. (#17718)
There were rendering bugs when the prompt was at the bottom of the screen. Removing the custom rendering helped fix the problems. (#17691)
When in explore and :nu returns null, you can now q/esc out. (#17661)
Fixed a bug where numerical keys in records mess up type inference, e.g. let foo: string = {1: 1} is allowed before the fix. As a side effect, previously forbidden key names, like{1kb: 1}, are valid now. (#17684)
Nushell now resolves symlinks via $env.PWD if that dir is the same as std::env::current_dir to allow formatted paths. (#17720)
Fixed a bug where creating nushell scripts with subcommands would show duplicate subcommands. (#17727)
Fixed the variable_not_found error in scenarios with recursive functions. (#17726)
Default arguments now allowed to have the same name as the parameter. (#17697)
Avoided input listen --timeout panic from double counting. (#17744)
reject now preserves the stream metadata. For example, ls | reject ...[] will keep the LS_COLORS and ansi links. (#17775)
Reject format strings with tokens after ending quote. (#17777)
Fixed a regression of v0.111.0 that made http commands not respect environment variables for proxying like ALL_PROXY. (#17794)
Fixed an issue where read-only directories are unable to be copied due to the mode attribute being preserved by default. (#17791)
Nushell now resolves library paths with user‑provided -I entries before the default NU_LIB_DIRS, fixing cases where bundled modules shadowed user scripts. NU_LIB_DIRS is also correctly treated as immutable at startup to avoid unexpected mutation in config or scripts. (#17819)
Added a simple check to prevent histogram output from having overlapping names when a named column is passed to the histogram. So now histograms of columns named "count", "frequency" (or the frequency user-defined name), "quantile", "percentage" will have sensible output. (#17783)
group-by now correctly groups rows when the grouper values are compound types like lists or records. Previously, grouping could collapse distinct values into the same bucket due to a lossy abbreviation of the compound key. (#17837)
Fixed the command tee truncating the input for the inner closure when the output of tee is ignored by subsequent commands. (#17793)
Aligns http options with the other http verbs so flags and output shape match http head. (#17841)
Fixed a bug of lossy parsing of unclosed subexpressions in string interpolation, e.g. $'(foo', which blocks completions inside all kinds of string interpolation subexpressions. (#17851)
rm now errors when given a symlink path with a trailing slash, preventing accidental deletion of the underlying directory. Use rm foo-link without the trailing slash to remove the symlink itself. (#17847)
Fixed a bug of duration/filesize parsing with numbers started by ., e.g. .5sec (#17923)
Made MCP more responsive in stdio mode. (#17945)
Use strict comparison for float-based sorting to fix panics. (#17930)
nu --experimental-options ... script.nu now works correctly without requiring -- before the script path. Nushell no longer treats the script file as part of the --experimental-options values. (#17943)
parse simple patterns: literal { via (char lbrace) before a {name} capture works now. (#17962)
Fixed input list when stdin is redirected in Unix TTY environments. (#17987)
