Life cycle changes

  • dots_splice() is deprecated. This function was previously in
    the questioning lifecycle stage as we were moving towards the
    explicit !!! splicing style.

  • flatten(), squash(), and their variants are deprecated in favour
    of purrr::list_flatten() and purrr::list_c().

  • child_env() is deprecated in favour of env() which has supported
    creating child environments for several years now.

Main new features

  • last_error() and options(rlang_backtrace_on_error = "full") now
    print the full backtrace tree by default (except for some hidden
    frames). The simplified backtraces tended to hide important context
    too often. Now we show intervening frames in a lighter colour so
    that they don't distract from the important parts of the backtraces
    but are still easily inspectable.

  • global_entrace(), last_warnings(), and last_messages() now
    support knitr documents.

  • New rlang_backtrace_on_warning_report global option. This is
    useful in conjunction with global_entrace() to get backtraces on
    warnings inside RMarkdown documents.

  • global_entrace() and entrace() now stop entracing warnings and
    messages after 20 times. This is to avoid a large overhead when 100s
    or 1000s of warnings are signalled in a loop (#1473).

  • abort(), warn(), and inform() gain an .inherit parameter.
    This controls whether parent is inherited. If FALSE,
    cnd_inherits() and try_fetch() do not match chained conditions
    across parents.

    It's normally TRUE by default, but if a warning is chained to an
    error or a message is chained to a warning or error (downgraded
    chaining), .inherit defaults to FALSE (#1573).

  • try_fetch() now looks up condition classes across chained errors
    (#1534). This makes try_fetch() insensitive to changes of
    implementation or context of evaluation that cause a classed error
    to suddenly get chained to a contextual error.

  • englue() gained env, error_arg, and error_call arguments to
    support being wrapped in another function (#1565).

  • The data-masking documentation for arguments has been imported from
    dplyr. You can link to it by starting an argument documentation with
    this button:

    <[`data-masking`][rlang::args_data_masking]>
    
  • enquos() and friends gain a .ignore_null argument (#1450).

  • New env_is_user_facing() function to determine if an evaluation
    frame corresponds to a direct usage by the end user (from the global
    environment or a package being tested) or indirect usage by a third
    party function. The return value can be overridden by setting the
    "rlang_user_facing" global option.

Miscellaneous fixes and features

  • New check_data_frame() and check_logical() functions in
    standalone-types-check.R (#1587, @mgirlich).

  • Added allow_infinite argument to check_number_whole() (#1588, @mgirlich).

  • The lifecycle standalone file has been updated to match the modern
    lifecycle tools.

  • parse_expr() now supports vectors of lines (#1540).

  • Quosures can now be consistently concatenated to lists of quosures (#1446).

  • Fixed a memory issue that caused excessive duplication in list2()
    and friends (#1491).

  • Embraced empty arguments are now properly detected and trimmed by
    quos() (#1421).

  • Fixed an edge case that caused enquos(.named = NULL) to return a
    named list (#1505).

  • expr_deparse() now deparses the embrace operator {{ on a single
    line (#1511).

  • zap_srcref() has been rewritten in C for efficiency (#1513).

  • zap_srcref() now supports expression vectors.

  • The non-error path of check_dots_unnamed() has been rewritten in C
    for efficiency (#1528).

  • Improved error messages in englue() (#1531) and in glue strings in
    the LHS of := (#1526).

  • englue() now requires size 1 outputs (#1492). This prevents
    surprising errors or inconsistencies when an interpolated input of
    size != 1 makes its way into the glue string.

  • arg_match() now throws correct error when supplied a missing value
    or an empty vector (#1519).

  • is_integerish() now handles negative doubles more consistently
    with positive ones (@sorhawell, #1530).

  • New check_logical() in standalone-types-check.R (#1560).

  • quo_squash() now squashes quosures in function position (#1509).

  • is_expression() now recognises quoted functions (#1499).
    It now also recognises non-parsable attributes (#1475).

  • obj_address() now supports the missing argument (#1521).

  • Fixed a check_installed() issue with packages removed during the
    current R session (#1561).

  • new_data_mask() is now slightly faster due to a smaller initial mask size
    and usage of the C level function R_NewEnv() on R >=4.1.0 (#1553).

  • The C level r_dyn_*_push_back() utilities are now faster (#1542).

  • The C level r_lgl_sum() and r_lgl_which() helpers are now faster
    (#1577, with contributions from @mgirlich).

  • rlang is now compliant with -Wstrict-prototypes as requested by CRAN
    (#1508).

  • as_closure(seq.int) now works (#1468).

  • rlang no longer stores errors and backtraces in a org:r-lib
    environment on the search path.

  • The low-level function error_call() is now exported (#1474).

  • Fixed an issue that caused a failure about a missing is_character
    function when rlang is installed alongside an old version of vctrs (#1482).

  • Fixed an issue that caused multiline calls in backtraces.

  • The C API function r_lgl_which() now propagates the names of the input
    (#1471).

  • The pkg_version_info() function now allows == for package
    version comparison (#1469, @KryeKuzhinieri).

  • Fixed backtrace display with calls containing long lists of
    arguments (#1456).

  • New r_obj_type_friendly() function in the C library (#1463). It
    interfaces with obj_type_friendly() from compat-obj-type.R via a
    C callable.

  • is_installed() no longer throws an error with irregular package
    names.

  • is_installed() and check_installed() now properly detect that
    the base package is installed on older versions of R (#1434).

  • Child errors may now have empty messages to enable this pattern:

    Error in `my_function()`:
    Caused by error in `their_function()`:
    ! Message.
    
  • The rlib_bytes class now uses prettyunits to format bytes. The
    bytes are now represented with decimal prefixes instead of binary
    prefixes.

  • Supplying a frame environment to the call argument of abort()
    now causes the corresponding function call in the backtrace to be
    highlighted.

    In addition, if you store the argument name of a failing input in
    the arg error field, the argument is also highlighted in the
    backtrace.

    Instead of:

    cli::cli_abort("{.arg {arg}} must be a foobar.", call = call)
    

    You can now write this to benefit from arg highlighting:

    cli::cli_abort("{.arg {arg}} must be a foobar.", arg = arg, call = call)
    
  • abort(message = ) can now be a function. In this case, it is
    stored in the header field and acts as a cnd_header() method
    invoked when the message is displayed.

  • New obj_type_oo() function in compat-obj-type.R (#1426).

  • friendly_type_of() from compat-obj-type.R (formerly
    compat-friendly-type.R) is now obj_type_friendly().

  • options(backtrace_on_error = "collapse") and print(trace, simplify = "collapse") are deprecated. They fall back to "none"
    with a warning.

  • call_match() now better handles ... when dots_expand = FALSE.

  • list2(!!!x) is now faster when x is a list. It is now returned
    as is instead of being duplicated into a new list.

  • abort() gains a .trace_bottom argument to disambiguate from
    other .frame. This allows cli::cli_abort() to wrap abort() in
    such a way that .internal mentions the correct package to report
    the error in (#1386).

  • The transpose() compat is now more consistent with purrr when
    inner names are not congruent (#1346).

  • New reset_warning_verbosity() and reset_message_verbosity()
    functions. These reset the verbosity of messages signalled with
    warn() and inform() with the .frequency argument. This is
    useful for testing verbosity in your package (#1414).

  • check_dots_empty() now allows trailing missing arguments (#1390).

  • Calls to local functions that are not accessible through :: or
    ::: are now marked with (local) in backtraces (#1399).

  • Error messages now mention indexed calls like foo$bar().

  • New env_coalesce() function to copy bindings from one environment
    to another. Unlike approaches based on looping with [[<-,
    env_coalesce() preserves active and lazy bindings.

  • Chaining errors at top-level (directly in the console instead of in
    a function) no longer fails (#1405).

  • Warning style is propagated across parent errors in chained error
    messages (#1387).

  • check_installed() now works within catch-all tryCatch(error = )
    expressions (#1402, tidyverse/ggplot2#4845).

  • arg_match() and arg_match0() now mention the correct call in
    case of type error (#1388).

  • abort() and inform() now print messages to stdout in RStudio
    panes (#1393).

  • is_installed() now detects unsealed namespaces (#1378). This fixes
    inconsistent behaviour when run within user onLoad hooks.

  • Source references in backtraces and last_error()/last_trace() instructions
    are now clickable in IDEs that support links (#1396).

  • compat-cli.R now supports style_hyperlink().

  • abort(.homonyms = "error") now throws the expected error (#1394).

  • env_binding_are_active() no longer accidentally triggers active bindings
    (#1376).

  • Fixed bug in quo_squash() with nested quosures containing the
    missing argument.

  • Backtraces of parent errors are now reused on rethrow. This avoids
    capturing the same backtrace twice and solves consistency problems
    by making sure both errors in a chain have the same backtrace.

  • Fixed backtrace oversimplification when cnd is a base error in
    abort(parent = cnd).

  • Internal errors thrown with abort(.internal = TRUE) now mention
    the name of the package the error should be reported to.

  • Backtraces are now separated from error messages with a --- ruler
    line (#1368).

  • The internal bullet formatting routine now ignores unknown names
    (#1364). This makes it consistent with the cli package, increases
    resilience against hard-to-detect errors, and increases forward
    compatibility.

  • abort() and friends no longer calls non-existent functions
    (e.g. cli::format_error() or cli::format_warning) when the
    installed version of cli is too old (#1367, tidyverse/dplyr#6189).

  • Fixed an OOB subsetting error in abort().
