🇸🇪 svlang

Swedish NLP toolkit for translators.

Detect anglicisms, check translation consistency, and split compound words — all from the command line or Python.

Installation

pip install svlang

# With .po file support
pip install svlang[po]

CLI Usage

Svengelska detector

Find unnecessary anglicisms in Swedish text:

$ svlang svengelska -t "Vi behöver implementera en ny approach"
  ⚠️  «implementera» → genomföra, införa
  ⚠️  «approach» → tillvägagångssätt, metod

$ svlang svengelska -f my_translation.txt

Consistency checker

Find identical source strings with different translations:

$ svlang consistency file1.po file2.po
⚠️  2 inkonsistens(er) hittade:

  Källa: «Save»
    → «Spara»  (file1.po:12)
    → «Lagra»  (file2.po:45)

# Also supports Qt .ts files
$ svlang consistency translations/*.ts

Compound splitter

Split Swedish compound words into components:

$ svlang compound barnbok solstol nattljus
  barnbok → barn + bok
  solstol → sol + stol
  nattljus → natt + ljus

Python API

from svlang.checkers import SvengelskaChecker, ConsistencyChecker, CompoundSplitter

# Anglicisms
checker = SvengelskaChecker()
hits = checker.check("Ge mig lite feedback")
for h in hits:
    print(f"{h.word} → {h.suggestion}")

# Consistency
con = ConsistencyChecker()
con.add("Save", "Spara", "file1.po:12")
con.add("Save", "Lagra", "file2.po:45")
for issue in con.check():
    print(f"{issue.source}: {list(issue.translations.keys())}")

# Compound words
splitter = CompoundSplitter()
result = splitter.split("barnvagnshjul")
print(result.parts)  # ["barn", "vagn", "hjul"]
