Probably rightly so, because "...Utils" classes are better avoided.[1] > > I’d like to ask: > Would it be appropriate to introduce a new class such as `TextUtils` under > the `org.apache.commons.text` package to house general-purpose text-related > utility methods (like smart truncation, word counting, title casing, etc.)? Each of the examples inside the parentheses should be discussed separately in order to determine whether they are "general-purpose". Indeed, each of * smart truncation * word counting * title casing has specific features and potential variants that * either warrant a class of its own (e.g. "truncation"), * or may be too ill-defined (e.g. capitalization of a title depends on the language) to belong in a general-purpose library. Also, we should beware of implementing functionality that already exists (such as "countWords"[2]) Regards, Gilles [1] https://stackoverflow.com/questions/3340032/are-utility-classes-evil [2] https://stackoverflow.com/questions/5864159/count-words-in-a-string-method > > Alternatively, is there an existing class where such methods would be more > appropriate? > > Looking forward to your suggestions and guidance on this. > > Best regards, > Kunal Bhangale > > On Sat, Aug 2, 2025 at 2:41 PM Gilles Sadowski <gillese...@gmail.com> wrote: > > > Hi. > > > > Le sam. 2 août 2025 à 10:55, Kunal Bhangale > > <bhangalekunal2631...@gmail.com> a écrit : > > > > > > Hi Commons Lang Developers, > > > > > > I would like to propose the addition of some new utility methods to > > > `StringUtils` in Apache Commons Lang.
