Function Documentation

ustring Archon::Utilities::Text::escapeNonprintable (  const ustring &  s  )

Todo: Should detect any nonprintable unicode character, but only deals with the 8-bit ISO8859-1 subset. Definition at line 233 of file text.C. References Archon::Utilities::Unicode::decodeUtf8().

string Archon::Utilities::Text::format (  string  , int  width = 0 )

Formats text to a certain width, or flatterns text to one line if "width" < 0. Below a text is viewed as consisting of words delimited by sequences of white-space characters. In this context white-space characters are considered to be: " ", SP, space "\t", HT, horizontal tab "\r", CR, carrage return "\n", LF/NL, line-feed/new-line All sequences of white-space characters are reduced to one of: a single space one or more newline characters nothing depending on where it occurs in the text and the value of "width" (especially whether it is negative or not.) Existing line brakings: If "width" >= 0 then newline characters occuring in the source text are preserved, except when they occur at the end of the text, that is, when no words follow. if "width" < 0 then newline characters are discarded. Line splitting: If "width" > 0 then lines are split into pieces, so that each resulting line has a maximum length of "width". Whenever possible the splitting is done right after the last word that fits on the line. This only fails if we encounter a word that is wider than "width". In this case the word is split into as many lines as needed in such a way that all except the last line have length exactly equal to "width". Definition at line 266 of file text.C.

string Archon::Utilities::Text::lineTrim (  string   )

Strip leading and trailing blank lines. While trim will eliminate any indent on the first line of the input this function retains that indent. Otherwise they are identical. Definition at line 167 of file text.C. Referenced by Archon::Utilities::FormatLibjpeg::load().
