Indent - Maple Help

StringTools

 Indent
 indent text a specified amount

 Calling Sequence Indent( s ) Indent( s, lineindent )

Parameters

 s - Maple string; string to be indented lineindent - {posint,string}; (optional) number of spaces or string to use for indent

Description

 • The procedure Indent indents a string s by replacing the beginning of each line in s by lineindent spaces, if lineindent is a non-negative integer, or if lineindent is a string by that string.
 • The indented string is returned.
 • The lineindent argument is optional. It is equal to $8$ by default, which causes the input text to be indented by $8$ spaces.
 • All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.

Specifying an indent amount is just a special case of specifying an indent string.
