Detailed Description

Utility functions for std::strings. Most of them based on stringutil::form.


Function Documentation

std::ostream & stringutil::dumpOn std::ostream &  str,
const std::vector< std::string > &  l,
const bool  numbered = false
 

std::ostream & stringutil::dumpOn std::ostream &  str,
const std::list< std::string > &  l,
const bool  numbered = false
 

Helper for stream output

std::string stringutil::form const char *  format,
  ...
[inline]
 

Printf style building of strings via format string.

std::string ex( stringutil::form( "Example number %d", 1 ) ); std::cout << ex << stringutil::form( " and number %d.", 2 ) << endl;

Will print: Example number 1 and number 2.

std::string stringutil::getline std::istream &  str,
const bool  trimed = false
 

Return one line read from istream. Aftrwards the streampos is behind the delimiting '
' (or at EOF). The delimiting '
' is not returned.

If trim is true, the string returned is trimmed (surrounding whitespaces removed).

ifstream s( "somefile" );

while ( s ) { string l = getline( s ); if ( !(s.fail() || s.bad()) ) {

// 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. } } }

std::string hexstring unsigned long long  n,

[inline]
 

std::string hexstring unsigned char  n,
int  w = 4
[inline]
 

std::string hexstring char  n,
int  w = 4
[inline]
 

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).

hexstring(42) -> "0x0000002a" hexstring(42, 4) -> "0x2a" hexstring(42,-4) -> "0x2a"

std::string stringutil::join const std::vector< std::string > &  words_r,
const std::string &  sep_r = ""
 

Join strinngs in words_r using separator sep_r

std::string stringutil::ltrim const std::string &  s  ) 
 

Return string with leading/trailing/surrounding whitespace removed

[inline]
 

std::string numstring unsigned char  n,
int  w = 0
[inline]
 

std::string numstring char  n,
int  w = 0
[inline]
 

Print number. Optional second argument sets the minimal string width (' ' padded). Negative values will cause the number to be left adjusted within the string. Default width is 0.

numstring(42) -> "42" numstring(42, 4) -> " 42" numstring(42,-4) -> "42 "

[inline]
 

std::string octstring unsigned  n,
int  w = 5
[inline]
 

std::string octstring int  n,
int  w = 5
[inline]
 

std::string octstring unsigned char  n,
int  w = 4
[inline]
 

std::string octstring char  n,
int  w = 4
[inline]
 

Print number as octal value with leading '0'. 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 5 (4 for char).

octstring(42) -> "00052" octstring(42, 4) -> "0052" octstring(42,-4) -> "052 "

std::string stringutil::rtrim const std::string &  s  ) 
 

unsigned stringutil::split const std::string  line_r,
std::vector< std::string > &  words_r,
const std::string &  sep_t = "\t",
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||

std::list<std::string> splitToLines const std::string  text_r,
const std::string &  sep_r = "\n"
[inline]
 

Split string into a list of lines using any<

char in sep_r as line delimiter. The delimiter is stripped from the line.

splitToLines( "start\n\nend" ) -> { "start", "", "end" }

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"

std::string stringutil::toLower const std::string &  s  ) 
 

Return string converted to lower/upper case

std::string stringutil::toUpper const std::string &  s  ) 
 

std::string trim const std::string &  s  )  [inline]
