NAME

       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.

NAME

       textutil::split - Procedures to split texts

SYNOPSIS

       package require Tcl  8.2

       package require textutil::split	?0.7?

       ::textutil::split::splitn string ?len?

       ::textutil::split::splitx string ?regexp?

_________________________________________________________________

DESCRIPTION

       The package textutil::split provides commands that split strings by size and arbitrary regular expressions.

       The complete set of procedures is described below.

       ::textutil::split::splitn string ?len?
	      This  command  splits  the  given  string into chunks of len characters and returns a list containing these chunks. The argument len
	      defaults to 1 if none is specified. A negative length is not allowed and will cause the command to  throw  an  error.  Providing	an
	      empty  string as input is allowed, the command will then return an empty list. If the length of the string is not an entire multiple
	      of the chunk length, then the last chunk in the generated list will be shorter than len.

       ::textutil::split::splitx string ?regexp?
	      This command splits the string and return a list. The string is split according to the regular expression regexp instead of a simple
	      list  of	chars.	 Note  that if you parentheses are added into the regexp, the parentheses part of separator will be added into the
	      result list as additional element. If the string is empty the result is the empty list, like for	split.	If  regexp  is	empty  the
	      string is split at every character, like split does.  The regular expression regexp defaults to "[\t \r\n]+".
