Entab - Function Summary

Summary:

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

Usage:

entab string

Arguments:

string - The string argument. (must be: any-string)

Refinements:

/size - Specifies the number of spaces per tab.

number - The number argument. (must be: 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. 


    text: {
        no
        tabs
        in
        this
        sentence
    } 
    remove head remove back tail text
    probe text
    {        no
            tabs
            in
            this
            sentence
       }


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


    print entab copy text
    		no
    		tabs
    		in
    		this
    		sentence


    probe entab/size copy text 2
    {^-^-^-^-no
    ^-^-^-^-tabs
    ^-^-^-^-in
    ^-^-^-^-this
    ^-^-^-^-sentence
    ^-}


    print entab/size copy text 2
    				no
    				tabs
    				in
    				this
    				sentence

The opposite function is DETAB which converts tabs back to spaces: 


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


    probe detab text
    {        no
            tabs
            in
            this
            sentence
    }
