Help me to understand some regular expresions usage
Can someone explain me how those restatements are constructed
1. What is the logic to use a reg-expr in variable name
2. In first string - the '#' seems to mean 'everithing after next mached', but the '.' in reg-exp is a one character, here it seems it used litteraly. Why?
3. I guess '%%' means return part that match next expression? Is it correct?
4. Why the '()' used in second string? [0-9] - any digit; '+' one or more times; so, +[0-9] should return consecutive numbers from string?! What is the need in '()'
5. How to understand third line? What is done by that whith string of digits?
Thank you

__________________________________________________________________________________________________________________________________________________NAME
textutil::tabify - Procedures to (un)tabify strings
SYNOPSIS
package require Tcl 8.2
package require textutil::tabify ?0.7?
::textutil::tabify::tabify string ?num?
::textutil::tabify::tabify2 string ?num?
::textutil::tabify::untabify string ?num?
::textutil::tabify::untabify2 string ?num?
_________________________________________________________________DESCRIPTION
The package textutil::tabify provides commands that convert between tabulation and ordinary whitespace in strings.
The complete set of procedures is described below.
::textutil::tabify::tabify string ?num?
Tabify the string by replacing any substring of num space chars by a tabulation and return the result as a new string. num defaults
to 8.
::textutil::tabify::tabify2 string ?num?
Similar to ::textutil::tabify this command tabifies the string and returns the result as a new string. A different algorithm is used
however. Instead of replacing any substring of num spaces this command works more like an editor. num defaults to 8.
Each line of the text in string is treated as if there are tabstops every num columns. Only sequences of space characters containing
more than one space character and found immediately before a tabstop are replaced with tabs.
::textutil::tabify::untabify string ?num?
Untabify the string by replacing any tabulation char by a substring of num space chars and return the result as a new string. num
defaults to 8.
::textutil::tabify::untabify2 string ?num?
Untabify the string by replacing any tabulation char by a substring of at most num space chars and return the result as a new
string. Unlike textutil::tabify::untabify each tab is not replaced by a fixed number of space characters. The command overlays each
line in the string with tabstops every num columns instead and replaces tabs with just enough space characters to reach the next
tabstop. This is the complement of the actions taken by ::textutil::tabify::tabify2. num defaults to 8.
There is one asymmetry though: A tab can be replaced with a single space, but not the other way around.
