# Fortran namelist files in Python
# A Python module to parse Fortran namelist files

Read in a namelist file:
```
from namelist_python import read_namelist_file
namelist = read_namelist_file('SIM_CONFIG.nl')
import namelist_python
namelist = namelist_python.read_namelist_file('config.dat')
namelist.groups['foo']['bar']
```

`namelist` is an instance of `namelist_python.Namelist` and all groups are
stored in the attribute `groups` with each variable in a nested dictionary
structure (using `OrderedDict` so that the order will be remembered).
This creates an instance of `namelist_python.Namelist` whose attribute
`groups` holds the data in a nested ordered case-insensitive dictionary
structure.

Write a `Namelist` object back to a file:
```
with open('NEW_FILE.nl', 'w') as f:
with open('new_file.dat', 'w') as f:
f.write(namelist.dump())
```

`dump` takes an optional argument `array_inline` a boolean which sets whether
arrays should be inline or given in index notation.

If you use ipython there is usefull attribute called `data` which allows you to
do tab completion on the group and variable names, and do assignment:
If you use ipython or a another interactive REPL prompt you may want to use
the `data` attribute which allows you to do tab completion on the group and
variable names:

## Features
- Parses ints, floats, booleans, escaped strings and complex numbers.
- Parses arrays in index notation and inlined.
- Can output in namelist format.
- Tab-completion and variable assignment in interactive console

## Missing features
- Currently can't handle variable definitions across multiple lines
- Currently can't handle line continuations
- Currently can't handle lines with several parameters
- Comments are not kept, and so won't exist in output.
- Module does not help to create a Namelist object from scratch

## Contribute
Please send any namelist files that don't parse correctly or fix the code
yourself and send me a pull request :)
