The option -d, --dry-run gives you opportunity to see the results before you actually replace, rename or delete anything.
The option -t, --highlight with values m[atch] r[eplacement] gives you opportunity to see the match and the replacement side-by-side in the output.
The option '--evaluator' gives you opportunity to precisely define how the replacement string is computed.
Evaluator is a path to a library (dll file) which contains method that has signature compatible with MatchEvaluator i.e. string M(Match match).
Expected format is 'MyLib.dll,MyNamespace.MyClass.MyMethod'.
The more complicated a pattern is, the less readable it becomes when written in one line.
orang find --content "(?x)(?<=(\A|\.)\s*)\p{Ll}\w+\b"
The option f[rom-file] gives you opportunity to store pattern in a file where it can be formatted.
orang find --content "pattern.txt" from-file
or
orang find -c "pattern.txt" f
Note: Replacement string can be store in a file as well.
Goal: Capitalize first character of a word at the beginning of the text or at the beginning of a sentence.
Folder C:/Lib contains library Evaluator.dll which contains method N.C.M.
using System.Text.RegularExpressions;
namespace N
{
public static class C
{
public static string M(Match match)
{
return char.ToUpper(match.Value[0]) + match.Value.Substring(1);
}
}
}File pattern.txt has following content:
(?x) # set multiline option
(?<= # is preceded with
(\A|\.) # beginning of text or a dot
\s* # zero or more white-space characters
)
\p{Ll} # lowercase letter
\w+ # one or more word characters
\b # word boundary (between word and non-word character)
