Running codes

a-Shell supports the following coding languages:

  • Python (with pip)
  • Lua
  • Perl
  • JavaScript (without npm)
  • C/C++ (with WebAssembly)
  • Fortran (using f2c)

For JavaScript, see Run JavaScript. For C/C++, see Compile a simple command.

Python 3

you can run Python easily.

$ python
>>> print (“Hello, world!”)
Hello, world!

You can also install modules using pip. So far clang can not deal with Python modules properly, so they must be written in pure Python.

$ pip install requests
Defaulting to user installation because normal site-packages is not writeable

Lua and Perl

Here are examples about Lua and Perl.

$ lua
Lua 5.4.4  Copyright (C) 1994-2022 Lua.org, PUC-Rio
> print ("Hello, world!")
Hello, world!

Perl also works.

$ perl test.pl
Hello, world!

Fortran

With f2c, Fortran source files can be converted into C/C++.

pkg install f2c

{% hint style="info" %} TODO: The specific steps to use f2c to deal with Fortran programs. {% endhint %}
