Changes in version 0.2.0                        

New features

  - New abort() dual-channel error signaller (in log.R): emits a styled
    one-line event to the operator console (most-specific class name +
    caller bracket) and signals a condition whose $message field is
    plain text - safe to serialize into JSON/HTML/any ANSI-unaware sink.
  - abort() captures the call stack at the signal site and attaches it
    to the condition as $trace. Unlike base R's traceback() (which only
    populates .Traceback for uncaught errors), $trace survives
    tryCatch() and travels with the condition - useful for server-side
    handlers that ship errors to a browser-side debug pane.
  - New exported format_trace() helper: renders the $trace pairlist (or
    the condition itself) as a numbered, one-line-per-frame string.
  - abort() resolves the user's calling function via a stack walk that
    skips frames in this package and in base (tryCatch, doTryCatch,
    etc.). Both the console bracket and the condition's $call field
    point to the same user frame - so R's default error printer shows
    Error in my_func(x) : ... instead of bare Error: ..., regardless of
    how many check_* / clean_* wrappers sit between abort() and the
    caller.
  - New info(), warn(), success(), dbg() log helpers, all routed through
    msg() for consistent timestamp + glyph + caller-bracket formatting.
  - Error class hierarchy: every check_* / clean_* abort carries
    failure-mode classes (rtemis_null_input, rtemis_na_input,
    rtemis_type_error, rtemis_length_error, rtemis_range_error,
    rtemis_value_error, rtemis_dependency_error), all inheriting from
    rtemis_input_error - callers can catch input failures broadly or
    narrow to a specific failure mode via tryCatch().
  - New global option rtemis.show_caller (default TRUE): set to FALSE in
    .Rprofile to suppress the caller bracket on all log lines for the
    session.
  - format_caller() now auto-suppresses non-name expressions (anonymous
    function literals, inline do.call-style invocations) - no more
    [function (ws, req) {...] brackets cluttering logs from
    callback-heavy code.

Breaking changes

  - All check_* and clean_* functions now signal errors via abort() with
    structured condition classes rather than via cli::cli_abort(). Error
    message text changes from cli's {.var x} styling to plain
    backtick-quoted names (e.g. `x` cannot be NULL.). Code that matches
    on exact error message strings will need to be updated. Generic
    tryCatch(error = ...) handlers continue to work; handlers keyed on
    the previous rlang_error / cli-specific classes will need to be
    updated to the new rtemis_error hierarchy (which also gains
    structured failure-mode subclasses).
