Given an inputfile streets.txt to

hfst-pmatch2fst

like:

define CapWord UppercaseAlpha Alpha* ;
define StreetWordFr [{avenue} | {boulevard} | {rue}] ;
define DeFr [ [{de} | {du} | {des} | {de la}] Whitespace ] | [{d'} | {l'}] ;
define StreetFr StreetWordFr (Whitespace DeFr) CapWord+ ;
regex StreetFr EndTag(FrenchStreetName) ;

An interactive session with

hfst-pmatch

might look like:

hfst-pmatch streets.pmatch

> Je marche seul dans l'avenue des Ternes
Je marche seul dans l'<FrenchStreetName>avenue des Ternes </FrenchStreetName>

A pipeline version of the same looks as follows:

hfst-pmatch2fst < streets.txt > streets.hfst

echo "Je marche seul dans l'avenue des Ternes" | hfst-pmatch -v streets.hfst 

Je marche seul dans l'<FrenchStreetName>avenue des Ternes</FrenchStreetName>
