Ширина
Інтерпретатор все ще не працює (у мене ще є кілька невикористаних командних слотів). Репо з більшою документацією можна знайти тут .
Денніс додав Width до TIO менше хвилини тому: Спробуйте це онлайн!
Ширина - це езотерична мова на основі стека, яку я нещодавно розробив на основі ідей, які я вперше закинув у це питання . Він заснований цілком на тому, наскільки широким, більш-менш чистим буквою є "звичайний" шрифт. Єдині символи, які роблять що-небудь, - це літери, великі і малі літери. Усі інші символи ігноруються. Я розділяю букви на 10 різних категорій ширини, які утворюють 10 різних можливих дій у Width:
0: i j l # do while counter > 0
1: f r t I # end
2: c k s v x y z J # 0 in commands
3: a b d e g h n o p q u L # separator (no-op)
4: F T Z # push base 10 number, using left side row titles (width numbers); terminated with original char
5: A B E K P S V X Y # 1 in commands
6: w C D H N R U # 2 in commands
7: G O Q # push string literal; sets of 2 width numbers equate to index in printable ASCII; terminated with original char
8: m M # if top of stack
9: W # else
2, 5та 6надають доступ до команд, більшість з яких взаємодіють зі стеком. Додаткову інформацію можна знайти на info.txtсторінці в репортажі Github.
Це код Python інтерпретатора. У мене ще є кілька команд, які потрібно додати, і я розглядаю, як працювати з обробкою помилок, але в іншому випадку вона повинна бути повною. (Я також збираюся додати прапор в якийсь момент, щоб дозволити тестування з більш абстрактним синтаксисом, тому що в іншому випадку ця мова є великим болем для роботи)
