unscramble.go

Take some letters and find words that can be made with those letters

What?

unscramble.go

This is my first attempt at Go. I have no idea the conventions or best practices, so feel free to comment.\
I decided to try and create something similar to my boggle solver, particularly because I wanted an easy way to unscramble some words\
...And yes, I know there are utilities, but 1. Nothing more fun than doing to yourself, 2. I can feed it any words that I want

Example:

% go run ./unscramble.go  --letters exmaple --min 5 --max 5

Starting
Loading 279,496 words into dictionary
Finding words of 5 to 5 length
Found 4 words
Displaying 4 words
----
expel
maple
ample
pelma
----
Done

Example:

% go run ./unscramble.go  -l ebcdfghjklmnpqrstvwxz --min 7 -j 2>/dev/null | jq .

[
  "klephts",
  "lengths",
  "phlegms",
  "pschent",
  "schmelz"
]

Example:

echo "aeiouwx" | go run ./unscramble.go --sort l --limit 10 2>/dev/null

ae
xi
ou
aw
we
ax
wo
ox
xu
ai

Example:

echo aabcdfghjklmnpqrstvwxyz | ./unscramble --log-level 30 -j --filter "^a.*[ty]$"

Why?

Kinda covered this above, but mostly to try Go

Improvements?

Speed wise I think it's about as fast as it gets. Going to look at multithreading, but I think Go already does that

State?

No known bugs. Works.
