# hfst-lexc(1)

\=Compile lexc files into transducer

## NAME

hfst-lexc - =Compile lexc files into transducer

## SYNOPSIS

**hfst-lexc** \[*OPTIONS*...\] \[*INFILE1*...\]\]

## DESCRIPTION

Compile lexc files into transducer

### Common options:

- **-h**, **--help**

  Print help message

- **-V**, **--version**

  Print version info

- **-v**, **--verbose**

  Print verbosely while processing

- **-q**, **--quiet**

  Only print fatal erros and requested output

- **-s**, **--silent**

  Alias of **--quiet**

### Input/Output options:

- **-f**, **--format**=*FORMAT*

  compile into FORMAT transducer

- **-o**, **--output**=*OUTFILE*

  write result into OUTFILE

### Lexc options:

- **-A**, **--alignStrings**

  align characters in input and output strings

- **-E**, **--encode-weights**

  encode weights when minimizing (default is false)

- **-F**, **--withFlags**

  use flags to hyperminimize result

- **-M**, **--minimizeFlags**

  if **--withFlags** is used, minimize the number of flags

- **-R**, **--renameFlags**

  if **--withFlags** and **--minimizeFlags** are used, rename flags (for testing)

- **-x**, **--xerox-composition**=*VALUE* Whether flag diacritics are treated as ordinary

  symbols in composition (default is true).

- **-X**, **--xfst**=*VARIABLE*

  toggle xfst compatibility option VARIABLE.

- **-W**, **--Werror**

  treat warnings as errors

If INFILE or OUTFILE are omitted or -, standard streams will be used The possible values for FORMAT are { sfst, openfst-tropical, openfst-log, foma, optimized-lookup-unweighted, optimized-lookup-weighted }. VALUEs recognized are {true,ON,yes} and {false,OFF,no}. Xfst variables are {flag-is-epsilon (default OFF)}.

## EXAMPLES

- hfst-lexc -o cat.hfst cat.lexc

  Compile single-file lexicon

- hfst-lexc -o L.hfst Root.lexc 2.lexc 3.lexc

  Compile multi-file lexicon

### Using weights:

-

  LEXICON Root cat # "weight: 2" ;    Define weight for a word \<\[dog::1\]+\> # ;        Use weights in regular expressions

Using weights has an effect only if FORMAT is weighted, i.e. { openfst-tropical, openfst-log, optimized-lookup-weighted }.
