Curl macros introduction (part 1)

[RobertShiplett]

When passed a String identifier, all of these variants have the same effect (the proc is the clue that these simple macros are examples only):

Code:

{define-proc {up s:String}:String
    {return {s.to-upper-clone}}
}

{define-macro public {uc ?txt:text}
    {return {expand-template {up ?txt}}}
}

{define-macro public {ucv ?txt:verbatim}
    {return {expand-template {up ?txt}}}
}

{define-macro public {uctk ?txt:token}
    {return {expand-template {up ?txt}}}
}

{define-macro public {uce ?txt:expression}
    {return {expand-template {up ?txt}}}
}

{define-macro public {ucs ?txt:statement}
    {return {expand-template {up ?txt}}}
}

when called as

Code:

{def str:String = "testing macros"}

{uc   str}
{br}
{ucv  str}
{br}
{uctk str}
{br}
{uce  str}
{br}
{ucs  str}
