pyccel.codegen.printing.fcode module

Print to F90 standard. Trying to follow the information provided at www.fortran90.org as much as possible.

class pyccel.codegen.printing.fcode.FCodePrinter(filename, *, verbose, prefix_module=None)

Bases: CodePrinter

A printer for printing code in Fortran.

A printer to convert Pyccel’s AST to strings of Fortran code. As for all printers the navigation of this file is done via _print_X functions.

Parameters:

• filename (str) – The name of the file being pyccelised.

• verbose (int) – The level of verbosity.

• prefix_module (str) – A prefix to be added to the name of the module.

function_signature(expr, name)

Get the different parts of the signature of the function expr.

A helper function to print just the signature of the function including the declarations of the arguments and results.

Parameters:

• expr (FunctionDef) – The function whose signature should be printed.

• name (str) – The name which should be printed as the name of the function. (May be different from expr.name in the case of interfaces).

Returns:

A dictionary with the keys :

sig - The declaration of the function/subroutine with any necessary keywords. arg_code - A string containing a list of the arguments. func_end - Any code to be added to the signature after the arguments (ie result). arg_decs - The code necessary to declare the arguments of the function/subroutine. func_type - Subroutine or function.

Return type:

dict

get_function(name)

get_method(cls_name, method_name)

indent_code(code)

Add the correct indentation to the code.

Analyse the code to calculate when indentation is needed. Add the necessary spaces at the start of each line.

Parameters:

code (str | iterable[str]) – A string of code or a list of code lines.

Returns:

A list of indented code lines.

Return type:

list[str]

language = 'Fortran'

print_constant_imports()

Print the import of constant intrinsics.

Print the import of constants such as C_INT from an intrinsic module (i.e. a module provided by Fortran) such as iso_c_binding.

Returns:

The code describing the import of the intrinsics.

Return type:

str

print_kind(expr)

Print the kind(precision) of a literal value or its shortcut if possible.

Print the kind(precision) of a literal value or its shortcut if possible.

Parameters:

expr (TypedAstNode | PyccelType) – The object whose precision should be investigated.

Returns:

The code for the kind parameter.

Return type:

str

printmethod = '_fcode'
