pseudoc

pseudoc is a project I made for school because we needed to write our programs in three different formats: Pascal, pseudocode (similar in structure to pascal) and graphs.

The language is very rudimentary and the compiler full of bugs, some notable features are:

• Hand made parser
• Local type inference

There’s a cli which has the following options

pseudoc <input> [<output>]

If no output is specified then pseudocode is printed to stdout, otherwise if the output file has a pas extension pascal is produced, if the extension is dot the dot graphing language is outputted, otherwise pseudocode is emitted.

Example

/* C style comments are supported */
program test; // Optional (taken from the file name if not present)

/* body is our program main block */
body {
  // Variables need to be declared before usage
  // A semicolon must be added to all statements
  let a: int;
  // pseudoc provides two builtin `In` (equivalent of pascal `readln`) and
  // `Out` (equivalent of pascal `writeln`)
  In(a);
  // Types can be omitted and the compiler will try to infer them
  let double = a * 2;
  Out("The result of a*2 is ", double);
}
