## Usage

### As a library

#### With string input

```python
>>> from streamparser import parse
>>> lexical_units = parse('^hypercholesterolemia/*hypercholesterolemia$\[\]\^\$[^ignoreme/yesreally$]^a\/s/a\/s<n><nt>$^vino/vino<n><m><sg>/venir<vblex><ifi><p3><sg>$.eefe^dímelo/decir<vblex><imp><p2><sg>+me<prn><enc><p1><mf><sg>+lo<prn><enc><p3><nt>/decir<vblex><imp><p2><sg>+me<prn><enc><p1><mf><sg>+lo<prn><enc><p3><m><sg>$')
>>> for lexical_unit in lexical_units:
print('%s (%s) → %s' % (lexical_unit.wordform, lexical_unit.knownness, lexical_unit.readings))
```

hypercholesterolemia (<class 'streamparser.unknown'>) → [[SReading(baseform='*hypercholesterolemia', tags=[])]]
a\/s (<class 'streamparser.known'>) → [[SReading(baseform='a\\/s', tags=['n', 'nt'])]]
vino (<class 'streamparser.known'>) → [[SReading(baseform='vino', tags=['n', 'm', 'sg'])], [SReading(baseform='venir', tags=['vblex', 'ifi', 'p3', 'sg'])]]
dímelo (<class 'streamparser.known'>) → [[SReading(baseform='decir', tags=['vblex', 'imp', 'p2', 'sg']), SReading(baseform='me', tags=['prn', 'enc', 'p1', 'mf', 'sg']), SReading(baseform='lo', tags=['prn', 'enc', 'p3', 'nt'])], [SReading(baseform='decir', tags=['vblex', 'imp', 'p2', 'sg']), SReading(baseform='me', tags=['prn', 'enc', 'p1', 'mf', 'sg']), SReading(baseform='lo', tags=['prn', 'enc', 'p3', 'm', 'sg'])]]

#### With file input

```python
>>> from streamparser import parse_file
>>> lexical_units = parse_file(open('~/Downloads/analyzed.txt'))
>>> for lexical_unit in lexical_units:
print('%s (%s) → %s' % (lexical_unit.wordform, lexical_unit.knownness, lexical_unit.readings))
```

Høgre (<class 'streamparser.known'>) → [[SReading(baseform='Høgre', tags=['np'])], [SReading(baseform='høgre', tags=['n', 'nt', 'sp'])], [SReading(baseform='høg', tags=['un', 'sint', 'sp', 'comp', 'adj'])], [SReading(baseform='høgre', tags=['f', 'n', 'ind', 'sg'])], [SReading(baseform='høgre', tags=['f', 'n', 'ind', 'sg'])], [SReading(baseform='høgre', tags=['sg', 'nt', 'ind', 'posi', 'adj'])], [SReading(baseform='høgre', tags=['mf', 'sg', 'ind', 'posi', 'adj'])], [SReading(baseform='høgre', tags=['un', 'ind', 'pl', 'posi', 'adj'])], [SReading(baseform='høgre', tags=['un', 'def', 'sp', 'posi', 'adj'])]]
kolonne (<class 'streamparser.known'>) → [[SReading(baseform='kolonne', tags=['m', 'n', 'ind', 'sg'])], [SReading(baseform='kolonne', tags=['m', 'n', 'ind', 'sg'])]]
Grunnprinsipp (<class 'streamparser.known'>) → [[SReading(baseform='grunnprinsipp', tags=['n', 'nt', 'ind', 'sg'])], S[Reading(baseform='grunnprinsipp', tags=['n', 'nt', 'pl', 'ind'])], [SReading(baseform='grunnprinsipp', tags=['n', 'nt', 'ind', 'sg'])], [SReading(baseform='grunnprinsipp', tags=['n', 'nt', 'pl', 'ind'])]]
7 (<class 'streamparser.known'>) → [[SReading(baseform='7', tags=['qnt', 'pl', 'det'])]]
px (<class 'streamparser.unknown'>) → []

### From the terminal
