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
Features:
- Multiple, user specified separators
- Converting all text to lowercase
- Sorting chunks before comparing the chunks
- Different input options: Command line, two files, single file or standard input
- Statistics about the number of chunks and number of characters
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"
Compare two lines, but first convert them both to lowercase
line_diff --line1 "hello world" --line2 "Hello wOrld" -l
