This mini-compiler has its own lexical, syntactic and semantic analyzer. It is based on mostly on Python, which is also used as an intermediate language to generate the machine language by using python ply. ## Requirements: * Python (v3.7+) * Python ply `pip install ply` ## Use: You can start using it by using the following commands: * `python parser.py` for interpreted mode * `python parser.py file.dr` to compile a file ## Keywords (and equivalent in python): Keyword | Python ------------ | ------------- `kteb` | `print` `qra` | `input` `ila ` | `if` `wla ` | `else` `dir ` | `do` `ma7ed ` | `while` `lkola ` | `for` `khrej ` | `break` `kmel ` | `continue` `wa ` | `and` `aw ` | `or` `khate2 ` | `false` `s7i7 ` | `true` `mojod ` | `global` `walo ` | `None` `l3akss ` | `not` `ta3rif ` | `def` `red ` | `return` `jereb ` | `try` `masd9ch ` | `except` `akhiran ` | `finally` `tol ` | `len` `zid ` | `append` `kber ` | `extend` `n9s ` | `pop` `dkhel ` | `insert` `khwi ` | `clear` ## Features: * Variables * Comments * Control flow statements: - loops (while,do-while,for) - conditional statements - function calls - exceptions * Operators: - arithmetic : `+ - * / % ^` - comparison : `> >= y) # Output: khate2 kteb(x =y) # Output: khate2 kteb(x = 0){ kteb('The number is positive') } wla{ kteb('The number is negative') } ``` - We can have a `ila..wla` statement inside another `ila..wla` statement. This is called nesting in computer programming. ```Python num = qra("Enter a number: ") ila (num >= 0){ ila (num == 0){ kteb("Zero") } wla{ kteb("Positive number") } } wla{ kteb("Negative number") } ``` * **lkola** (*for loop*):\ The `lkola` loop is used to iterate over a sequence. ```Python lkola(i=0;i = 0){ red(num) } wla{ red(-num) } } kteb(absolute_value(2)) # Output: 2 kteb(absolute_value(-4)) # Output: 4 ``` > You'll find more examples in the examples folder! * **jereb..masd9ch..akhiran* …
