namelist_io

Read and write Fortran namelist (.nml) files for the 1D Euler solver.

This module defines the canonical list of config parameters (mirroring config_t in src/config.f90), their types, defaults, valid choices, and human-readable tooltips. The GUI config editor is driven entirely from :data:SCHEMA.

The parser is regex-based and handles scalar values only (matching the solver's own namelist usage).

Param(key, group, ptype, default, label, tooltip='', choices=list(), min_val=None, max_val=None) dataclass

Metadata for a single namelist variable.

defaults_dict()

Return {key: default} for every parameter.

parse_namelist(path)

Parse a Fortran namelist file into {group: {key: value}}.

flat_from_namelist(path)

Parse namelist and flatten into a single {key: value} dict.

write_namelist(values, path)

Write a namelist file from a flat {key: value} dict.

Only writes values that differ from the built-in defaults so the generated file stays concise.
