bench 1.1.4

• press() gains a new .quiet argument to silence progress messages (#145).

• The .grid argument of press() now subsets data.frames and tibbles consistently (#142).

• bench_time_trans() and bench_bytes_trans() once again apply pretty breaks correctly (#140, @plietar, @simonpcouch).

• R >=4.0.0 is now required, which is aligned with tidyverse standards.

• Switched to modern ggplot2 conventions internally (#141, @olivroy).

bench 1.1.3

• Long unnamed bench_expr expressions are now truncated correctly when used as columns of a tibble (#94).

• bench_mark tibbles now respect the knitr paged df option (#103).

• Fixed an issue where macOS specific C code paths were accidentally being used on GNU Hurd (#118).

• Fixed -Wstrict-prototypes warnings, as requested by CRAN (#124).

• R >=3.5.0 is now required, which is aligned with tidyverse standards.

• bench now uses testthat 3e (#129).

• bench no longer Suggests mockery.

bench 1.1.2

• Davis Vaughan is now the maintainer.

• autoplot.bench_mark() again supports factor levels for expression, as intended (#82)

• bench::mark() and bench::workout() no longer support unquote and splice operators. This fixes inconsistencies in performance results with functions like rlang::list2() (#61).

• bench has been re-licensed as MIT (#101).

bench 1.1.1

• mark() columns memory, result and mem_alloc columns are now always included, even if they are unused.

bench 1.1.0

New features

• New bench_process_memory() function, to return the current and maximum memory used by the current process. This uses system functions to track memory, so can measure memory outside of R’s GC heap.

• New workout_expressions() function, a low-level function to workout a list of expressions, like those obtained via parse() from a file.

• mark() gains a memory argument to control if it records memory allocations, set memory = FALSE to disable recording memory allocations, which can be helpful when trying to benchmark long pieces of code with many allocations (#62).

Minor improvements and fixes

• mark() now permits empty arguments, e.g. accidental trailing commas (#61).

• mark() now errors correctly when the expressions deparsed length is different.

• bench_expr objects now work better with the upcoming versions of tibble and vctrs (@romainfrancois, #64)

• autoplot.bench_mark() provides a more informative error if the ggbeeswarm package is not installed (@coatless, #69).

• Update documentation of bench_mark columns (@jdblischak, #67).

bench 1.0.4

• bench_memory() examples no longer fail if they are run with R that does not have memory profiling capability (#56).

• bench_expr now has a class of c("bench_expr", "list") rather than c("bench_expr", "expression"), as it is really a list of calls rather than a true expression object. (https://github.com/r-lib/vctrs/issues/559)

bench 1.0.3

• summary.bench_mark() gains a time_unit argument, so you can report all times in a consistent scale if desired (#18, #26).

• bench_mark() now checks for user interrupts, to allow you to stop benchmarking if it takes longer than you were expecting (#49).

• New bench_memory() to capture just the memory allocated by an expression.

• bench_time() is now an alias for system_time().

• unnest.bench_mark() is now compatible with the upcoming tidyr 1.0.0 (#48, #51)

• New hires_time() allows you to explicitly capture high resolution time points.

bench 1.0.2

• workout() a new function which makes timing multiple expressions in turn simpler.

• mark() now internally uses a tempfile rather than a textConnection, as the latter has a 100,000 character limit on some platforms (#27)

• mark() no longer returns the mean or max values and the column order has been tweaked to try and put the most interesting columns first (#37)

• Errors during evaluation now halt execution (#28, #43)

• scale_bench_time() and scale_bench_bytes() now allow you to use a non-logarithmic scale.

bench 1.0.1

• Add support for macOS versions prior to 10.12
• Disable load sensitive tests on CRAN, to avoid failures

bench 1.0.0

• Added a NEWS.md file to track changes to the package.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
