v0.4.5

Bug fixes

• handle two types of + signs in terminal mode
  • Here I had to make a design choice. Now terminal-mdoe ggbash CANNOT
    contain whitespaces between aes names and values
    (i.e. Bad : size = 3 + .5 and Good: size=3+.5)
    This is because without parentheses and commas, there are almost
    no clues that differentiate between "ggplot2 plus" (connecting
    layers) and "R's plus" (an operator for addition).
    The hope is that in NSE mode ggbash can still include whitespaces
    between aes names and values. I hope this would not lead to users'
    frustration.
• handle redundant aes() specification (simply remove it)

v0.4.4

Bug fixes

• handle grouped_df case NSE in ggbash()
• add partial match preference when exact match
  (p should return p instead of price,
  even if the latter comes first)
• fix %>% and aes() case
• layer-specific data specification
• add . (dot) in parsing rules of variable names

Version 0.4.3: %>% operator

Enhancements

• handling of magritrr %>% operator
  • turned out to be harder than expected.
    ggplot2-compiler cannot recognize what . operator means,
    so the contents of . have to be properly set in temporary
    variable (ggbash_piped) in ggbash() and exec_ggbash().

v0.4.2

Bug Fixes

• handling of ..density.. or ..prop.. (four dots variables)
• handling of binwidth = c(1, 1)
• handling of group=1
• handling of internal stat_bin_hex
• add tests for geom_crossbar, geom_freqpoly, etc.

NSE

Additional Features

• Non-standard evaluation (NSE) interface
• handling of x=1 (scalar variable)
• handling of R functions (turned out to be complicated)

Bug Fixes

• remove : in theme elements names and / in save_ggplot arguments. This is because or R's language restriction for more handy NSE. This supersede grammar rules determined in v0.2 change.

Approx String Match & Interface to Other ggplot2 Extensions

Major Updates

Approximate String Matching

• Approximate String Matching reduces programmer's stress because
  we usually type tokens only by its consonants.
  • aesthetics (size by sz)
  • theme configuration (legend.key by l.key, or legend.box.background by l.b.b)

Interface to other ggplot2 extensions

• The main scope of ggbash is to make a compiler for default ggplot2 functions.
  Handling ggplot2 extension libraries within ggbash() arguments
  should increase complexity
  and might significantly slows down the development process.
  As a remedy, ggbash() now returns a ggplot2 object (not a string) by ggbash(),
  and can chain other geom_ or theme_ objects by the normal + operator in ggplot2.
  • Ex. ggbash("gg(iris, Sepal.W, Sepal.L) + point(col=Spec, size=5) ") + geom_text_repel(aes(label=Species))

Bug Fixes

• add docs tests of various geoms

v0.3.3

Bug Fixes

• locate bin2d bins=10
• add syntax sugars (remove habitual commas and spaces)
• defaultZproblem (see by grep)
• start docs test of geom_countour, geom_point, and so on

ggbash 0.3.2

Bug Fixes

• get stats (method="lm" in geom_smooth, binwidth=30 in geom_histogram)
  by get_stat_params
• get special flags like weight in geom_bar
• start docs test of geom_abline and geom_bar
• show colnames of previously-used data frame
• fix parentheses mismatch
  • one problem is unnecessary parentheses (legend.position = ("none") or
    panel.ontop = (TRUE))...
  • This is deceptively simple but hard to solve because of
    the current parsing production rules.
  • some rules can't know if element_text is
    placed before the current token.

v0.3.1

Bug Fixes

• error handlings
  • missing required geoms gg mtcars + text mpg cyl
    • needed to rewrite production rules
  • special geom parameters (check_overlap, etc.)
  • general p_error

ggbash 0.3.0: Implement fixit

Major Updates

Fixit

• From this v0.3.0, ggbash incorporates a powerful feature called fixit.
  It's inspired from a modern C++ compiler
  clang's Fix-It Hints.
  Now when ggbash users input a string which contains some typos,
  ggbash gives users useful information on
  what might be needed to fix the compile error.
  • For example, if users wrongly input
    the column name like gg iris + point Sepl.W Sepal.L,
    ggbash gives Column name not found error
    and also displays that the most similar column names are
    Sepal.Width, Species, Sepal.Length, Petal.Width, Petal.Length,
    in this order.
    This could significantly reduce the learning cost of ggplot2 and ggbash,
    having a possibility of making ggbash suitable for new ggplot2 users
    as well as its heavy users.

Other Bug Fixes

• checked coding style according to jimhester/lintr package.
• renamed partial_match_utils.R to prefix_match.R (more accurate)
