diffr {diffr}

Diff 2 files side by side

Description

Takes the diff of 2 files and shows comparisons

Usage

diffr(file1, file2, contextSize = 3, minJumpSize = 10, wordWrap = TRUE,
  before = file1, after = file2, width = NULL, height = NULL)

Arguments

file1

First file to take diff (usually original file)

file2

First file to take diff (usually updated file)

contextSize

Minimum number of lines of context to show around each diff hunk. (default: 3).

minJumpSize

Minimum number of equal lines to collapse into a “Show N more lines” link. (default: 10)

wordWrap

By default, code will go all the way to the right margin of the diff. If there are 60 characters of space, character 61 will wrap to the next line, even mid-word. To wrap at word boundaries instead, set this option.

Examples

library(diffr)
file1 = tempfile()
writeLines("hello, world!\n", con = file1)
file2 = tempfile()
writeLines(paste0(
"hello world?\nI don't get it\n",
paste0(sample(letters, 65, replace = TRUE), collapse = "")), con = file2)
diffr(file1, file2, before = "f1", after = "f2")
