NAME
textutil::string - Procedures to manipulate texts and strings. SYNOPSIS
package require Tcl 8.2 package require textutil::string ?0.7? ::textutil::string::chop string ::textutil::string::tail string ::textutil::string::cap string ::textutil::string::uncap string ::textutil::string::longestCommonPrefixList list ::textutil::string::longestCommonPrefix ?string...? _________________________________________________________________ DESCRIPTION
The package textutil::string provides miscellaneous string manipulation commands. The complete set of procedures is described below. ::textutil::string::chop string A convenience command. Removes the last character of string and returns the shortened string. ::textutil::string::tail string A convenience command. Removes the first character of string and returns the shortened string. ::textutil::string::cap string Capitalizes the first character of string and returns the modified string. ::textutil::string::uncap string The complementary operation to ::textutil::string::cap. Forces the first character of string to lower case and returns the modified string. ::textutil::string::longestCommonPrefixList list ::textutil::string::longestCommonPrefix ?string...? Computes the longest common prefix for either the strings given to the command, or the strings specified in the single list, and returns it as the result of the command. If no strings were specified the result is the empty string. If only one string was specified, the string itself is returned, as it is its own longest common prefix.
