REBOL 3 Functions: entab

entab string /size number

Converts spaces in a string to tabs (default tab size 4). (Modifies)

Arguments:

string [any-string!]

Refinements:

/size - Specifies the number of spaces per tab

number [integer!]

Description

The REBOL language default tab-size is four spaces. Use the /size refinement for other sizes such as eight. entab will only place tabs at the beginning of the line (prior to the first non-space character).

The series passed to this function is modified as a result.

probe entab text
{^-no
   tabs
   in
   this
   sentence}

probe detab text
{    no
    tabs
    in
    this
