Global

Definition

Global preprocessor configuration and shared runtime state.

This type encapsulates all user-configurable options controlling the behaviour of the fpx preprocessor.

A single public instance, global, is provided and used throughout the library. Applications may modify its components before starting preprocessing to customize parsing rules, enable extensions, or predefine symbols.

Examples

use fpx_global
use fpx_macro
call add(global%macros, macro('__LFORTRAN__','1'))
global%extra_macros = .true.
global%support_forloop = .true.
fpx_global::global
type(global_settings), public global
Global preprocessor configuration instance.
Definition global.f90:192
fpx_macro::add
Append macros to a macro table.
Definition macro.f90:175
fpx_macro::macro
Representation of a preprocessor macro.
Definition macro.f90:135

Remarks

  • The settings remain active for the duration of the preprocessing session.
  • Components may be modified at any time before calling preprocess.
  • The global instance is intended for single-threaded use.
