read one line from a stream Return one line read from istream. Afterwards the streampos is behind the delimiting '

' is not returned.
If trim is true, the string returned is trimmed (surrounding whitespaces removed).

// l contains valid data to be consumed. // In case it makes any difference to you: if ( s.good() ) { // A delimiting '
' was read. } else { // s.eof() is set: There's no '
' at the end of file. // Note: The line returned may netvertheless be empty if trimed is true. } } }

Print number as hex value with leading '0x'. Optional second argument sets the minimal string width (0 padded). Negative values will cause the number to be left adjusted within the string. Default width is 10 (4 for char).

const bool | singlesep_r = false |

Split line into words
singlesep_r = false: Separator is any nonenmpty sequence of characters listed in sep_t. Leading trailing separators are ignored.
Example: singlesep_r = false, sep_t = ":"
"" -> words 0 ":" -> words 0 "a" -> words 1 |a| "::a" -> words 1 |a| "::a::" -> words 1 |a| ":a::b:c:"-> words 3 |a|b|c|
singlesep_r = true: Separator is any single character occuring in sep_t. Leading trailing separators are not ignored (i.e will cause an empty word).
Example: singlesep_r = true, sep_t = ":"
"" -> words 0 ":" -> words 2 ||| "a" -> words 1 |a| ":a" -> words 2 ||a| "a:" -> words 2 |a|| ":a:" -> words 3 ||a||

Split string into a list of lines using any< > char in sep_r as line delimiter. The delimiter is stripped from the line.

string stringutil::stripFirstWord | ( | std::string & | value, |
const bool | ltrim_first = false |
||
) |
Strip the first word (delimited by blank or tab) from value, and return it. Adjust value to start with the second word afterwards.
If value starts with blank or tab, the first word is empty and value will be ltrimmed afterwards.
If ltrim_first is true, value will be ltrimmed before stripping the first word. Thus first word is empty, iff value is empty or contains whitespace only.
stripFirstWord( "1st" ) == "1st" and value truncated to "" stripFirstWord( "1st word" ) == "1st" and value truncated to "word" stripFirstWord( " 1st word" ) == "" and value truncated to "1st word" stripFirstWord( " 1st word", true ) == "1st" and value truncated to "word"
