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. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category textutil of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. SEE ALSO

textutil::trim - Procedures to trim strings SYNOPSIS
package require Tcl 8.2 package require textutil::trim ?0.7? ::textutil::trim::trim string ?regexp? ::textutil::trim::trimleft string ?regexp? ::textutil::trim::trimright string ?regexp? ::textutil::trim::trimPrefix string prefix ::textutil::trim::trimEmptyHeading string _________________________________________________________________ DESCRIPTION
The package textutil::trim provides commands that trim strings using arbitrary regular expressions. The complete set of procedures is described below. ::textutil::trim::trim string ?regexp? Remove in string any leading and trailing substring according to the regular expression regexp and return the result as a new string. This is done for all lines in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string. The regular expression regexp defaults to "[ \t]+". ::textutil::trim::trimleft string ?regexp? Remove in string any leading substring according to the regular expression regexp and return the result as a new string. This apply on any line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string. The regular expression regexp defaults to "[ \t]+". ::textutil::trim::trimright string ?regexp? Remove in string any trailing substring according to the regular expression regexp and return the result as a new string. This apply on any line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string. The regular expression regexp defaults to "[ \t]+". ::textutil::trim::trimPrefix string prefix Removes the prefix from the beginning of string and returns the result. The string is left unchanged if it doesn't have prefix at its beginning. ::textutil::trim::trimEmptyHeading string Looks for empty lines (including lines consisting of only whitespace) at the beginning of the string and removes it. The modified string is returned as the result of the command. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems.
