line_diff

Tool to make a diff between to single lines. The intended use case is to compare long lines where parts are different or missing. For example:

• long command lines with many arguments and flags
• Compiler commands with many paths (with potentially different order)
• Long function declarations with slightly different arguments

Example output

Line 1: 
cargo run -- -o --file l1.txt -s " ;"
Line 2:
cargo run --release -- --file l1.txt -s " ;" -o

Examples

Compare two lines from two different input files.

line_diff l1.txt l2.txt

Compare two lines from two different input files. With the -o option the chunks will be sorted before comparison. This is handy for cases such as compiler flags where the ordering does not matter.

line_diff l1.txt l2.txt -o

Compare two lines from two a single input file and with sorting of the chunks. Specify two different separators (' ' and ';') with the -s option

line_diff --file l1.txt -o -s "; "

Compare two lines by specifying the string on the command line

line_diff --line1 "hello world" --line2 "hello there"
