[heronshoes]

RedAmber v0.4.1 has released 🎉

This release contains bug fixes and small updates from 0.4.0 . Topix for this release is below:

Bug fix

• Do not create new objects (returns self) for empty renaming/dropping or picking itself.
• Fixed #to_s and #to_iruby for usability.
• Support sorting after joining for all mutating and filtering joins.

Class SubFrames

• Upgrade SubFrames#aggregate to accept block
• Ensure baseframe's schema for SubFrames
  Also see Introduction to SubFrames.

Update Vector functions

• Vector#modulo, #quotient methods
  • The divmod function in Arrow C++ is still in draft state.
    This method was created by combining existing functions
• Add Vector#*_checked functions
  • This functions will check numeric range overflow.

Introduce REPL environment

• bin/example with pre-loaded sample datasets.

[0.4.1] - 2023-03-11

• Breaking change

  • Remove Vector.aggregate? method (Update subframes #200)

• Bug fixes

  • Return self in DataFrame#drop when dropper is empty (reverts 746ac26) (Update DataFrame #193)
  • Return self in DataFrame#rename when renaming to same name (Update DataFrame #193)
  • Return self in DataFrame#pick when pick itself (Fix join and pick #199)
  • Fix column width for non-ascii elemnts in DataFrame#to_s (Update DataFrame #193)
    • This change uses String#width.
  • Fix DataFrame#to_iruby when data is date32 type (Update DataFrame #193)
  • Fix DataFrame#shorthand to show temporal type data simply (Update DataFrame #193)
  • Fix Vector#rank when data is ChunkedArray (Update vector #198)
  • Fix Vector element-wise functions with nil as scalar (Update vector #198)
  • Support :force_order for all methods of join family (Fix join and pick #199)
    • Supports :force_order option to force sorting after join for all #join familiy.
    • This will valuable in some cases such as large dataframes.
  • Ensure baseframe's schema for SubFrames (Update subframes #200)

• New features and improvements

  • Add Vector#first, #last method (Update vector #198)
    • This method will be used in SubFrames feature.
  • Add Vector#modulo method (Update vector #198)
    • The divmod function in Arrow C++ is still in draft state.
      This method was created by combining existing functions
  • Add Vector#quotient method (Update vector #198)
  • Add aliases #div, #mod, #mul, #pow, #quo and #sub for Vector (Update vector #198)
  • Add Vector#*_checked functions (Update vector #198)
    • This functions will check numeric range overflow.
  • Add 'tdra' and 'plain' in display mode (Update DataFrame #193)
    • The plain mode and default inspect will show up to 128 rows and 128 columns.
  • Add String#width method in refinements (Update DataFrame #193)
    • This will be used to update DataFrame#to_s.
  • Introduce pre-loaded REPL environment (Fix join and pick #199)
    • This commit will add bin/example and it will start irb environment
      with enabled commonly used datasets such as penguins, diamonds, etc.
  • Upgrade SubFrames#aggregate to accept block (Update subframes #200)

• Refactoring

  • Use symbolized keys in refinements of Table#keys, #key? (Update DataFrame #193)
    • This can be treat Tables and DataFrames as same manner.
  • Use key_name.succ in suffix of DataFrame#join (Update DataFrame #193)
    • This will make simple to get name candidate.
  • Use ||= to memorize instance variables (Update DataFrame #193)
  • Refine vector projection to use #variables (Update DataFrame #193)
    • #variables is fastest when picking Vectors.
  • Refine Vector#is_in to avoid #pack (Update vector #198)
  • Refine Vector#index (Update vector #198)

• Improve in tests/CI

  • Tests

    • Update benchmarks to test from older version (Update DataFrame #193)
    • Refine test of Vector function with scalar (Update vector #198)
    • Refine test subframes and test_vector_selectable (Update subframes #200)

  • Cops
