![]() The latest Macro compiler can compile any valid Harbour code including code to pre-process before compile. In other words, any Harbour application may be extended and modified at runtime to compile and execute additional code on-demand. private, or public variables, or a database field.Īdditionally, the Macro Operator may compile and execute function calls, complete assignments, or even list of arguments, and the result of the macro may be used to resolve any of the above contexts in the compiled application. the right side of an assignment (rvalue), but such a compiled expression may be used to resolve the left side (lvalue) of an assignment, i.e. Such a compiled expression may be used as a VALUE, i.e. Harbour's implementation of the Macro Operator allows for runtime compilation of any valid Harbour expression. One of the most powerful features of xBase languages is the Macro Operator '&'. Harbour has an active development community and extensive third party support.Īny xBase language provides a very productive way to build business and data intensive applications. Harbour is 100% Clipper-compatible and supports many language syntax extensions including greatly extended run-time libraries such as OLE, Blat, OpenSSL, FreeImage, GD, hbtip, hbtpathy, PCRE, hbmzip ( zlib), hbbz2 ( bzip2), cURL, Cairo, its own implementation of CA-Tools, updated NanFor libraries and many others. ![]() HBIDE application is a sample of HBQt potential. ![]() HBQt is a library providing bindings to Qt. HBQt, HWGui, MiniGUI (latest version based on Qt and QtContribs ) and commercial (e.g. Harbour supports external GUIs, free (e.g. Harbour can make use of multiple Graphic Terminal emulations, including console drivers, and Hybrid Console/GUIs, such as GTWvt, and GTWvg. Harbour can use the following C compilers, among others: As 2010 many efforts have been made to turn the transition from other xBase dialects easier. Most software originally written to run on Xbase++, FlagShip, FoxPro, xHarbour and others dialects can be compiled with Harbor with some adaptation. Under Linux and Windows Mobile, Clipper source code can be compiled with Harbour with very little adaptation. Under Microsoft Windows, Harbour is more stable but less well-documented than Clipper, but has multi-platform capability and is more transparent, customizable and can run from a USB flash drive. As the same compiler is available for all of the above operating systems, there is no need for recoding to produce identical products for different platforms, except when operating system dependent features are used. Unlike Java which is intended to be write once, run anywhere, Harbour aims to be write once, compile anywhere. Although this is true, xBase is more than a simple database system as the same time xBase languages using purely DBF can not provide full concept of a real RDBMS. XBase technologies often is confused with a RDBMS software. MySQL, PostgreSQL, SQLite, Firebird, Oracle are examples of databases which Harbour can connect. ![]() Harbour also offers ODBC support by means of an OOP syntax, and ADO support by means of OLE. NETIO and LetoDB provide remote access over TCP protocol. DBFNTX implementation has almost same functionality of DBFCDX and RDDSIX. Third-party RDDs, like RDDSQL, RDDSIX, RMDBFCDX, Advantage Database Server, and Mediator exemplify some of the RDD architecture features. The RDD architecture allows for inheritance, so that a given RDD may extend the functionality of other existing RDD(s). In Harbour multiple RDDs can be used in a single application, and new logical RDDs can be defined by combining other RDDs. It offers multiple RDDs such as DBF, DBFNTX, DBFCDX, DBFDBT and DBFFPT. Harbour extends the Clipper Replaceable Database Drivers (RDD) approach. In 2009 Harbour was substantially redesigned, mainly by Viktor Szakáts and Przemyslaw Czerpak. Harbour is a synonym for port (where ships dock), and Harbour is a port of the Clipper language. The name "Harbour" was proposed by Linares, it is a play on a Clipper as a type of ship. Antonio Linares founded the Harbour project and the implementation was started in March 1999. ![]() The idea of a free software Clipper compiler had been floating around for a long time and the subject has often cropped up in discussion on. ![]()
