Display diff of object definitions
Description
Display diff of object definitions
Usage
construct_diff(
target,
current,
...,
data = NULL,
pipe = NULL,
check = TRUE,
compare = compare_options(),
one_liner = FALSE,
template = getOption("constructive_opts_template"),
mode = c("sidebyside", "auto", "unified", "context"),
interactive = TRUE
)
Arguments
target |
the reference object |
current |
the object being compared to |
... |
Constructive options built with the |
data |
Named list or environment of objects we want to detect and mention by name (as opposed to deparsing them further). Can also contain unnamed nested lists, environments, or package names, in the latter case package exports and datasets will be considered. In case of conflict, the last provided name is considered. |
pipe |
Which pipe to use, either |
check |
Boolean. Whether to check if the created code reproduces the object
using |
compare |
Parameters passed to |
one_liner |
Boolean. Whether to collapse the output to a single line of code. |
template |
A list of constructive options built with |
mode , interactive |
passed to |
Value
Returns NULL
invisibly, called for side effects
Examples
## Not run:
# some object print the same though they're different
# `construct_diff()` shows how they differ :
df1 <- data.frame(a=1, b = "x")
df2 <- data.frame(a=1L, b = "x", stringsAsFactors = TRUE)
attr(df2, "some_attribute") <- "a value"
df1
df2
construct_diff(df1, df2)
# Those are made easy to compare
construct_diff(substr, substring)
construct_diff(month.abb, month.name)
# more examples borrowed from {waldo} package
construct_diff(c("a", "b", "c"), c("a", "B", "c"))
construct_diff(c("X", letters), c(letters, "X"))
construct_diff(list(factor("x")), list(1L))
construct_diff(df1, df2)
x <- list(a = list(b = list(c = list(structure(1, e = 1)))))
y <- list(a = list(b = list(c = list(structure(1, e = "a")))))
construct_diff(x, y)
