Saya suka konsep 0815 , kecuali penerjemah di situs web pembuatnya mengembalikan Kesalahan 404. Jadi saya memutuskan untuk meminta Anda semua untuk membantu!

Dasar

0815 didasarkan pada tiga (3) register dan antrian. Register diberi nama X, Y, dan Z, dengan X menjadi hanya-tulis, Z menjadi hanya-baca, dan Y menjadi register "pembantu" yang tidak dapat diakses secara langsung. Semua register mulai diatur ke 0. Semua angka dalam heksadesimal.

Instruksi

Catatan: Beberapa instruksi mengambil parameter yang diformat seperti di }:hello:mana :hello:parameternya. Catatan lain: Beberapa deskripsi instruksi tidak jelas, jadi saya mengambil beberapa kebebasan dengannya. (Instruksi asli di sini )

~ berarti parameter diperlukan

----------|---|--------------------------------------------
  ~Move   | < | <:8: will write 8 to X (parameter required) 
----------|---|--------------------------------------------
   Swap   | x | Swap X and Y
----------|---|--------------------------------------------
  ~Label  | } | }:hello: makes a label called 'hello'
----------|---|--------------------------------------------
  Input   | | | Set X to an integer from input in 
 Number   |   | hexadecimal greedily (regex: [0-9A-F]+)
----------|---|--------------------------------------------
  Input   | ! | Set X to the ASCII code of one ASCII
  ASCII   |   | character in the input
----------|---|--------------------------------------------
  Print   | % | Prints an integer stored in Z 
  number  |   | (hexadecimal base)
----------|---|--------------------------------------------
  Print   | $ | Prints an ASCII char stored in Z
  ASCII   |   |
----------|---|--------------------------------------------
  Roll    |   | Rolls all registers to the left
Registers | ~ | X <- Y <- Z <- X
  Left    |   | After roll: X = Y, Y = Z and Z = X
----------|---|--------------------------------------------
  Roll    |   | Rolls all registers to the right
Registers | = | X -> Y -> Z -> X
  Right   |   | After roll: Y = X, Z = Y and X = Z
----------|---|--------------------------------------------
 ~Jump if | ^ | ^:loop: Jumps to the label 'loop' if Z is
 not zero |   | not zero
----------|---|--------------------------------------------
 ~Jump if | # | #:loop: Jumps to the label 'loop' if Z is
   zero   |   | zero
----------|---|--------------------------------------------

Instruksi Antrian

----------|---|--------------------------------------------
   Clear  | ? | Clears the queue
----------|---|--------------------------------------------
  Enqueue | > | Enqueue the number stored in Z
----------|---|--------------------------------------------
  Dequeue | { | Dequeue a number into X
----------|---|--------------------------------------------
          |   | Rolls the queue to the left, wrapping as
   Roll   |   | necessary. The first number becomes the 
   Queue  | @ | last; second becomes first and so on. Can  
   Left   |   | take a parameter to roll a certain number
          |   | of times. @:b: rolls 11 times.
----------|---|--------------------------------------------
   Roll   |   | 
   Queue  | & | The opposite of @
   Right  |   | 
----------|---|--------------------------------------------

Instruksi aritmatika

----------|---|--------------------------------------------  
   Add    | + | Z = X + Y
----------|---|--------------------------------------------
 Subtract | - | Z = X - Y
----------|---|--------------------------------------------
 Multiply | * | Z = X * Y
----------|---|--------------------------------------------
  Divide  | / | Z = X / Y
          |   | Y = remainder
----------|---|--------------------------------------------

Cobalah online! (Contohnya adalah program nomor Collatz / hailstone dari situs web penulis bahasa.)

Catatan:

• Mengambil kode 0815 sebagai argumen baris perintah pertama dan input sebagai yang kedua. Ya, ini agak canggung (apalagi di TIO, di mana Anda mendapatkan kotak teks terpisah), tetapi Pip tidak terlalu pandai membaca semua stdin.
• Angka dalam input harus menggunakan digit hex huruf besar (sesuai OP: cocok dengan regex [0-9A-F]+). Jika, pada |instruksi, karakter input berikutnya tidak 0-9A-F, pembacaan gagal dan menyebabkan perilaku yang berpotensi aneh. Ini berarti program genap penulis tidak bekerja seperti yang tertulis ... Saya tidak yakin bagaimana ia mengharapkan beberapa angka dibaca berfungsi, tapi saya hanya menerapkan sesuai dengan apa yang dikatakan spec.
• Jika label digandakan, lompatan masuk ke yang pertama. Jika label tidak ada, lompatan menghentikan program.

Python 3, 1320 byte

Versi yang tidak disatukan, serta analisis (dan jika perlu, versi yang diperbaiki) dari program pengujian, dapat ditemukan di intisari ini .

Keputusan desain:

• Berbagai definisi label diabaikan. Hanya definisi pertama label yang digunakan. (Sebelumnya definisi yang paling baru dilihat akan digunakan, tetapi itu dihapus.)
• Input sesuai dengan spesifikasi OP: input numerik membaca karakter hex dengan rakus. (Awalnya akan membaca hingga baris baru, dan kesalahan ketika karakter non-hex dibaca.)
• Input "ASCII" diartikan sebagai input "byte-oriented". (Awalnya itu memiliki dukungan Unicode penuh, yang mengambil lebih sedikit kode berkat menjadi Python 3 ... tetapi memenuhi poin-poin berikutnya berarti membaca byte demi byte sekarang lebih pendek.)
• Parameter di mana tidak ada parameter yang diharapkan diabaikan; karenanya, mereka dapat digunakan sebagai komentar.

Ada masalah dengan contoh program menggunakan CR saja sebagai baris baru mereka (kadang-kadang), yang membuat shell saya menimpa baris saat ini daripada memulai yang baru. Ini memengaruhi program Fibonacci Sequence dan 99 Bottles of Beer. Ayat terakhir dari 99 Botol Bir juga tidak mencetak dengan benar, dan saya masih menyelidiki sebabnya.

Scala, 3,123 2,844 2,626 2,540 byte

Selain kendala yang dijabarkan dalam pertanyaan, juru bahasa ini ditulis untuk bersandar sebanyak mungkin terhadap prinsip-prinsip FP. Secara khusus:

• Hanya struktur abadi
• Semua fungsi murni

Ini dicapai, dengan pengecualian dari empat baris kode yang menggerakkan loop utama dari interpreter. Struktur yang tidak dapat diubah sangat sulit untuk digunakan di sini karena keadaan register mendorong aliran kontrol dari loop (khususnya dua pernyataan GOTO). Saya masih berpikir tentang bagaimana mengubahnya menjadi menggunakan struktur murni & tidak dapat diubah, tetapi itu tidak relevan dengan tantangan golf kode.

Dikompilasi dengan:

flex -o 0815.cpp 0815.ll
g++ -std=c++11 0815.cpp -o 0815 -ll

Mungkin dikompilasi dengan lexes lain juga, tapi saya tidak memeriksanya. Ia bekerja dalam dua lintasan, sehingga lompatan ke depan ditangani dengan benar. Nama label diizinkan untuk memulai dengan angka, karena itu terjadi lebih dari satu kali dalam kasus uji. Hex literal hanya dapat huruf besar, sesuai dengan spesifikasi.

Lewati semua kasus uji, termasuk yang ditemukan di Esolangs Wiki dan halaman 0815. Penanganan kesalahan tidak ada dan keluar pada label yang tidak dikenal tidak anggun, setelah semua ini adalah kode-golf.

Saya sedang mempersiapkan penerjemah yang tidak disolf (dan jauh lebih baik) untuk rilis, sehingga OP dapat terus bermain-main dengan 0815. Tetap disini :)
