Re: Commons Lang substitution

[Alex Soto]

Thanks for your help but sadly doesn't work as expected. Look:

Map map = new HashMap();
map.put("version", "1");

StrSubstitutor strSubstitutor = new StrSubstitutor(map, "$", "");
strSubstitutor.setVariableSuffixMatcher(StrMatcher.trimMatcher());
System.out.println(strSubstitutor.replace("The $version is
awesome"));

prints: The 1is awesome

Notice that it eats the white space.

Alex.

Instead of guessing, I'd rather have a look into the Javadocs of 
StrSubstitutor.

Hi, thank you for your answers, Jörg I think that StrMatcher is for
implementing where you want to get information to be replaced on the
string, not for parsing issues.

I think Jörg is right.

You may change the suffix StrMather through
#setVariableSuffixMatcher() on a StrSubstitutor.
I haven't tried it, but it should be something like this example:

final Map valueMap = ...;
StrSubstitutor  subst = new StrSubstitutor(valuesMap, "$", ""); //
NONE_MATCHER for suffix initially
subst.setVariableSuffixMatcher(StrMatcher.trimMatcher());

HTH,

Woonsan

Hello,

Yes, this is correct. The replace with blank could be implemented using a
custom StrLookup. However, it is not possible to configure a StrSubstitutor
to use only a starting character.

End "character" could be any non-alphanum character. Isn't it what the 
StrMatcher could be used for?
