Examples compiled with Harbour + HBUtil

hb32\contrib\hbutil. To compile:

hbmk2 test1.prg hbutil.hbc

1 - Variable declaration and automatic initialization

LOCAL | STATIC | PUBLIC | PRIVATE <var, ...> AS <TYPE>

// Extended commands (override) 

// Declare and initialize variables
LOCAL nPos(1), nSize AS INTEGER
LOCAL nPrice, nTotal(3) AS MONEY // nPrice:=0.00, nTotal:=0.000
LOCAL tDat1, tToday(), tDat3 AS TIMESTAMP
LOCAL dDat1, dToday(), dDat3 AS DATE // dDat1:=CTOD(''), dToday:=DATE()
LOCAL lStart, lEnd AS LOGICAL
LOCAL hItem AS HASH
LOCAL aTypes[3], aItems AS ARRAY
// Harbour native (just declare variables)
LOCAL oBrw AS CLASS TBROWSE
LOCAL oCol, oGet, oPrn AS OBJECT
LOCAL bInit, bAction AS BLOCK

5 implementation suggestions

(I implemented the first 4)

1 - Declaration & initialization. Syntax:  

LOCAL | STATIC | PUBLIC | PRIVATE <var, ...> AS <TYPE>

// <TYPE> = ARRAY, CHARACTER, DATE, HASH, LOGICAL, MEMO, NUMERIC, TIMESTAMP
// artificial: CHAR, INTEGER, DECIMAL, MONEY

features:

• declare and initialize variables with empty value
• DATE/TIMESTAMP allow to initialize with current date/datetime
• some types accept arguments in variable
• for types derived from NUMERIC, it will format the value, but is not useful at runtime
• CHAR, INTEGER, DECIMAL, MONEY are artificial types for types C, N, N, N
• Other AS <TYPE> are not overridden by HBUtil:
• AS OBJECT
• AS BLOCK
• AS POINTER
• AS CLASS <TName> ...

 2 - Runtime parameter validation (functions and methods) . Syntax:
