⚠️⚠️⚠️WARNING⚠️⚠️⚠️: OUT OF MAINTAINCE

The Pi-Lang project, originally designed for "military race", have been out of maintaince for a while. In general, Pi-Lang has embedded worst parts of Pascal, Python and JavaScript, and it is extremely not recommended to use it in any product. I'm still glad to provide information about its implementations.

Pi-Lang introduction

brief

PiLang is a tiny programming language for very beginners and casual devices such as raspberry pi and smart phones. "Pi" means raspberry Pi, a kind of small computer for educations.

Features

No Shift key

PiLang avoids using shift key which is indended for inputing special characters frequently.

C++:

int rfact(int n) {
  if (n == 1) return 1;
  else return n * rfact(n-1);
}

PiLang:

function rfact takes n returns f begin
  if n eq 1 then
    f = 1;
  else
    f = n times rfact[n minus 1];
  end if
end function

PiLang eliminates shift keys by replacing symbols with corresponding words. This is useful when user does not have a standard keyboard. However, It is also possible to use these symbols directly. What's more, one symbol may have more than one replacement, so it is unnecessary to memorize these replacements.

Dynamically typed

PiLang is dynamically typed. Variable does not have to be declared before its first use, and PiLang does not require types to be written out explicitly. This may be friendly to freshmen. However, type annonations are also possible, and linting tools will come out soon. There will never be any type annonations and linting tools.

Building from source

Building on linux

To build PiLang on linux, you need the following packages

• markdown
• YACC(bison) note: lex is not required
• tree
• cc

For debian users, simply install these packages by apt:

sudo apt install bison markdown gcc tree

Checkout the project with git, get into the pilang directory, and then make.

Building on windows

To build PiLang on windows, it is recommended to use a MinGW32 GCC compiler, mingw32-make and a GnuWin32 Bison. These packages will soon be available for download from icey's site. After installing these packages, simply get into the pilang directory and then

mingw32-make --file="makefile.win"
