Initially it went over the list of words & checked if they exist in the grid. This was very slow.
Currently it walks the grid & checks if the current string exist in the dictionary. This is faster for these reasons:
- The dictionary is sorted, we perform binary range search on the dictionary to return the list of all words that start with specific string.
- Starting positions are limited.
If the dictionary wasn’t sorted then this probably would’ve been slower than previous implementation.
neighbors subroutine (
lib/Octans/Neighbors.rakumod) was taken from
my AoC (Advent of Code) 2020’s day-11 solution.
Octans’s default dictionary file is
flag to change the dictionary. The words in dictionary must be seperated
by a newline (
\n) & sorted alphabetically.
Generates a video solution for the puzzle.
Minimum word length to look for. Default is 7.
The path to be passed must be a readable file or an url in either format:
- Link when you view it from your local instance: https://tilde.zone/web/statuses/105531207939242077
- Link from Algot’s profile: https://mastodon.art/@Algot/105333136907848390
This will increase verbosity.
v0.2.5 - 2023-07-02
- Fixed puzzle output with visualize turned off.
Earlier the program would output a bunch of new lines, etc. The issue was that word-search subroutine was passed
:visualizewhich sets that flag to always true and that caused weird behaviour, this has been fixed.
v0.2.3 - 2022-01-12
- Add visualize option.
--visualizenow generates a video solution for the puzzle using Cairo and ffmpeg.
v0.2.0 - 2021-03-04
--samplewill not solve the sample puzzle.
- Removed shorthand for verbose option
-vwon’t work in
- Change representation of visited squares
--verbosewas passed, it would print the solved puzzle with visited squares replaced with fancy characters. Now it marks them by adding:
*to visited + gray squares (start positions)
/to visited squares
- Removed time taken
Time taken won’t be printed anymore.
It was misleading because the time printed was not the time taken to find that specific word, it was the time taken to find all the words upto that word. It would reset for each starting position.
v0.1.4 - 2021-02-19
- Fixed the puzzle parsing regex
The older regex fails to parse this puzzle: https://mastodon.art/@Algot/105690195742318751.
v0.1.3 - 2021-01-24
- Added an option to specify minimum word length.
v0.1.2 - 2021-01-20
- Input puzzle can now be of any size & not restricted to 4x4 grid.
v0.1.1 - 2021-01-20
- Read puzzle from a file.
v0.1.0 - 2021-01-19
- Improved performance by using a better algorithm to find words in the grid.
