swipeGuess

swipeGuess is a completion program intended to be used as a plugin for touchscreen-keyboards on mobile devices.

For each line input from stdin, it looks through a wordlist and outputs the first possible match for that gesture.

it's run like input-program | swipeGuess wordlist.txt | output-program

input-program

The input program should output a stream of letters "swiped through", then a newline.

This is supported by wvkbd since version 0.6.

wordlist

This should be a list of words, sorted by preferability of choice.

Good starting points can be found on the web, based on your language.

Example English Word Lists

• http://www-personal.umich.edu/~jlawler/wordlist - 69,903 English words, including obscure words, missing common stems.
• http://www.mieliestronk.com/corncob_lowercase.txt - 58,110 English words with British spelling.
• https://raw.githubusercontent.com/dwyl/english-words/master/words.txt - 466,550 words, including many proper nouns like names.
• https://norvig.com/ngrams/count_1w.txt - 333,333 words, abbreviations, etc, sorted by popularity.
• https://www.keithv.com/software/wlist/index.php - page with several links providing intersections between english word lists (26,680 - 1,516,998 words)

sorting tips

The most basic sorting technique would put longest words first, otherwise, it may be impossible to type them.

# Good autocompletion for terminal
ls $PATH | awk '{ print length, $0 }' | sort -nr | cut -d" " -f2- > binsSorted.txt

Smarter sorting would be keyboard-layout aware. mapscore.py can do that for you

./mapScore.py map.tsv <words.txt | sort -nr | cut -f2 > wordsSorted.txt

map.tsv uses tabs and newlines to create the grid-based layout. See map.qwerty.simplegrid.tsv for a sample of how to format this file.

If your keys are in a hexagonal layout, use mapScore like ./mapScore.py map.simple.tsv bee.

output-program

• completelyTypeWord.sh (included in this repository) will type the characters (besides the first character, which is already typed by wvkbd) using wtype.

Installation/Usage with wvkbd

1. Be using a wayland-based graphical shell (such as sway)
2. Compile with your favorite C compiler: gcc swipeGuess.c -o swipeGuess.
3. copy swipeGuess completelyTypeWord.sh into your $PATH (~/.local/bin/ or /usr/local/bin/ for example)
4. wvkbd-mobintl -O | swipeGuess /path/to/words.txt | completelyTypeWord.sh
   • In SXMO, KEYBOARD_ARGS='-O | swipeGuess /path/to/words.txt | completelyTypeWord.sh' can be added to your ~/.profile to enable this (effective on restart).
