pillar 1.3.0 2018-07-14

Visible changes

  • Unknown data types are formatted using format(), not as.character() (#120).

  • Multi-tier colonnades can always fill the last tier, even if the width isn’t a proper multiple of getOption("width"). (Example: options(width = 80, tibble.width = 200) will print a wide tibble in three tiers, each 80 characters wide, with a total width of 240 characters.)

  • Fixed mixed formatting (showing some pillars with maximum, and some with minimum width). If a pillar’s minimum width is smaller than getOption("width"), it is shown nevertheless, abbreviated with dots if necessary.

Interface changes

Performance improvements

  • Printing large multi-tier colonnades is much faster, the code that distributes pillars over tiers uses a much simpler and much faster algorithm (tidyverse/tibble#422).

  • Printing is now faster overall, because less work is done for formatting in “subtle” style (gray of a fixed level), and because fansi::strip_sgr() is used instead of crayon::strip_style().

  • Slightly faster printing of colonnades by reusing an intermediate result.

Internal

  • pillar() no longer adds backticks if title is non-syntactic.

  • colonnade() supports data frames and matrices. When printing, each sub-column is shown individually, using a title that resembles the syntax used to access it. Also supports recursively nested data frames (with data frame or matrix columns).

  • Added fuzz tests for character colonnades of varying widths.

  • Use fansi::substr_ctl() in favor of crayon::col_substr().

pillar 1.2.3 2018-05-25

  • Eliminate CRAN check warning about undeclared withr dependency.
  • More defensive test to address CRAN check failures on Solaris.
  • colonnade() now handles pillars named "sep" (#115).
  • pillar_shaft.character() gains min_width argument.

pillar 1.2.2 2018-04-26

  • Whole numbers are printed without a decimal dot again. Numbers that are the result of a whole number divided by a power of 10 (subject to a tolerance to account for floating-point imprecision) are shown without trailing decimal zeros, even if these zeros are significant according to the pillar.sigfig option (#105).
  • New new_pillar_title() and new_pillar_type() to support consistent output in glimpse() (#31).
  • New format_type_sum() generic that allows overriding the formatting of the type summary in the capital (#73).
  • The digits.secs option is respected when computing the width for date-time values (#102).

pillar 1.2.1 2018-02-27

Display

  • Turned off using subtle style for digits that are considered insignificant. Negative numbers are shown all red. Set the new option pillar.subtle_num to TRUE to turn it on again (default: FALSE).
  • The negation sign is printed next to the number again (#91).
  • Scientific notation uses regular digits again for exponents (#90).
  • Groups of three digits are now underlined, starting with the fourth before/after the decimal point. This gives a better idea of the order of magnitude of the numbers (#78).
  • Logical columns are displayed as TRUE and FALSE again (#95).
  • The decimal dot is now always printed for numbers of type numeric. Trailing zeros are not shown anymore if all displayed numbers are whole numbers (#62).
  • Decimal values longer than 13 characters always print in scientific notation.

Bug fixes

  • Numeric values with a "class" attribute (e.g., Duration from lubridate) are now formatted using format() if the pillar_shaft() method is not implemented for that class (#88).
  • Very small numbers (like 1e-310) are now printed corectly (tidyverse/tibble#377).
  • Fix representation of right-hand side for getOption("pillar.sigfig") >= 6 (tidyverse/tibble#380).
  • Fix computation of significant figures for numbers with absolute value >= 1 (#98).

New functions

  • New styling helper style_subtle_num(), formatting depends on the pillar.subtle_num option.

pillar 1.1.0 2018-01-14

  • NA values are now shown in plain red, without changing the background color (#70).
  • New options to control the output, with defaults that match the current behavior unless stated otherwise:
    • pillar.sigfig to control the number of significant digits, for highlighting and truncation (#72),
    • pillar.subtle to specify if insignificant digits should be printed in gray (#72),
    • pillar.neg to specify if negative digits should be printed in red,
    • pillar.bold to specify if column headers should be printed in bold (default: FALSE, #76),
    • pillar.min_title_chars to specify the minimum number of characters to display for each column name (default: 15 characters, #75).
  • Shortened abbreviations for types: complex: cplx -> cpl, function: fun -> fn, factor: fctr -> fct (#71).
  • Date columns now show sub-seconds if the digits.secs option is set (#74).
  • Very wide tibbles now print faster (#85).
