text.regex.tdfa.text 1 provides instances regexlike regex text using internal text types. can instances of classes data.text.lazy derived instances of data.text.internal ? how can improve code? import qualified data.text.lazy t import text.regex.tdfa import text.regex.base.context() import text.regex.base.regexlike() import text.regex.tdfa.text import data.function (on) (<?>) :: t.text -> t.text -> bool (<?>) = on (=~) t.tostrict i might missing something, seems have missed the module containing lazy text instances regex-tdfa classes . if that's what's happening, need change import text.regex.tdfa.text to import text.regex.tdfa.text.lazy note called text in module data.text.internal same called text in data.text -- i.e., it's "strict" text . lazy text type defined in different internal module (basically specialized list of strict texts.) it's not though these 2 ways of viewing same thing, if that's ...

i have qvector of qstrings , want remove element content, don't know how find index of it. know how can remove it? don't want iterate on , compare content value. my qvector declared follows: qvector <qstring> user_valid; and want remove content, example element value "marigold": user_valid.remove(user_valid.find("marigold"); thank in advance! ok, following if you: use qstringlist instead of qvector<qstring> has convenience methods can useful you; more common , hence comprehensive. spare 1 method call in case. just use removeone() and/or removeall() methods depending on exact scenario. therefore, writing this: qstringlist user_valid; user_valid << "marigold" << "cloud" << "sun" << "rain"; user_valid.removeone("marigold"); // user_valid: ["cloud", ,"sun", "rain"] if insist on using qvector<qstring> ...
