$ wordler [path-to-word-list] [regex] [comma-separated list of characters to exclude]

$ wordler ~/Documents/words.txt "..a.." "c,h,i:4,r"

You will need cargo to run this with either cargo run or build with cargo build --release and then copy into your path. Follow the install instructions on the Rust website and use rustup.

If you are on macos, you may have to remove a previous version of the program before re-copying it as an executable, otherwise macos may kill the process. Change paths as necessary.

$ cargo build --release
$ rm ~/Developer/bin/wordler
$ cp target/release/wordler ~/Developer/bin/wordler

Shows valid words that match the regular expression and which exclude the characters given. Excluded characters can have the format of a single character to exclude from the entire word, or a character followed by a colon and index to exclude words that contain that character at that index. Characters may occur multiple times as excluded-at-index instances. i.e.

$ wordler ~/Documents/words.txt ".f..r" "a:2,e:0,e:2"

TODO:

• Refactor cli arguments using clap.
• Order results by best choice.
  • Possibilities here include ordering by the highest number of, and best match/shortest hamming/Damerau-Levenshtein (or other) distance to other words; lack of repeated characters in unknown positions, etc.
• Add logic for specifying that a character occurs more than once (shows up in Wordle as two more more blocks, 1 or more green, 1 or more yellow).
• Refactor to an interactive prompt where you input words you tried and specify whether they were correct.
