What is HarbourBuilder?

HarbourBuilder is a Borland C++Builder-style visual IDE that generates Harbour/xBase code. Drop controls from the palette, set properties in the inspector, double-click to write event handlers — and your app runs natively on Windows, macOS, and Linux with zero code changes.

Windows

macOS

Linux

📱 NEW — Now going Mobile

Drop controls. Hit Run. See your app on Android.

The same Harbour source that drives Windows, macOS and Linux desktops now produces a signed APK running on the Android emulator — with native android.widget.Button, TextView, EditText. No web view. No skinned UI. No runtime dependency.

What works today (Iteration 1)

✅ Harbour cross-compiled for ARM64 — 30 static libraries built against official harbour/core sources with NDK Clang, zero source changes
✅ End-to-end build pipeline — 8 stages: harbour → clang → aapt2 → javac → d8 → zipalign → apksigner
✅ One-click build from the IDE — menu Run → Run on Android... invokes the full pipeline, signs the APK and launches the emulator
✅ Native GUI backend — UI_FormNew, UI_LabelNew, UI_ButtonNew, UI_EditNew, UI_SetText, UI_GetText, UI_OnClick, UI_SetFormColor, UI_SetCtrlColor, UI_SetCtrlFont wired via JNI
✅ Density-aware layout — form-designer coordinates scale by DisplayMetrics.density so a 100-px button looks consistent on mdpi, hdpi, and xxhdpi screens
✅ IDE form designer → Android APK — drop controls, hit Run → Run on Android..., the IDE generates the UI_* code, builds a signed APK, boots the emulator, installs and launches — colors and fonts included
✅ Setup Wizard — menu Run → Android Setup Wizard... detects NDK, SDK, JDK, AVD, Harbour-for-Android libs; one click downloads + installs the ~2.8 GB toolchain
✅ Prebuilt Harbour-for-Android shipped in the repo (releases/harbour-android-arm64-v8a.zip, 3.6 MB) — no need to cross-compile Harbour from source; the wizard just extracts it
✅ Validated on Pixel 5 / Android 14 — AVD HarbourBuilderAVD, Harbour VM initialized, PRG Main() executed, widgets rendered, click events dispatched back to Harbour codeblocks

Coming next

🚧 ComboBox, ListView, RadioButton, CheckBox, DatePicker
🚧 Embedded adb logcat panel in the IDE (today it streams in a dedicated terminal window)
🚧 Device picker (emulator / USB / Wi-Fi ADB)
🚧 Keystore manager + release AAB export for Play Store
🚧 Setup Wizard port to macOS and Linux hosts
🚧 Multi-ABI prebuilts (x86_64, armeabi-v7a) in addition to the current arm64-v8a

Why this matters

No other Harbour IDE — classic or modern — targets mobile natively. HarbourBuilder is about to let tens of thousands of Harbour developers ship to every platform that matters from a single codebase.

iOS — coming soon

The iOS backend mirrors the Cocoa architecture we already ship on macOS: UIView instead of NSView, touch events instead of mouse, Xcode toolchain instead of clang. The same Harbour classes that target five desktops will soon also compile to a signed .ipa, ready for TestFlight and the App Store. Five platforms. One source. Harbour everywhere.

What you write:

#include "hbbuilder.ch"

function Main()
   local oForm, oBtn

   DEFINE FORM oForm TITLE "Hello World" SIZE 400, 300 FONT "Segoe UI", 10

   @ 120, 140 BUTTON oBtn PROMPT "Click Me!" OF oForm SIZE 120, 32
   oBtn:OnClick := { || MsgInfo( "Hello from HarbourBuilder!" ) }

   ACTIVATE FORM oForm CENTERED
return nil

What the IDE generates (two-way code sync from the visual designer):

// Form1.prg

CLASS TForm1 FROM TForm

   // IDE-managed Components

   // Event handlers

   METHOD CreateForm()

ENDCLASS

METHOD CreateForm() CLASS TForm1
   ::Title  := "Form1"
   ::Left   := 100
   ::Top    := 170
   ::Width  := 400
   ::Height := 300
return nil

Both styles run identically on Windows, macOS, and Linux — with native controls on each platform.

🔌 Connectivity (Language Interop)

Call any language from Harbour — or embed Harbour in any language:

Component	Mechanism	Use Case
Python	C API (`Py_Initialize`, `PyRun_SimpleString`)	AI/ML (TensorFlow, PyTorch), data science (pandas, numpy), scripting
Swift	Bridging header + `@objc` interop	Native macOS/iOS APIs, SwiftUI, Apple frameworks
Go	`cgo` FFI (`import "C"`)	Microservices, CLI tools, high-concurrency backends
Node	`child_process` / N-API addon	npm ecosystem, Electron UIs, REST APIs, real-time (Socket.io)
Rust	C ABI (`extern "C"` + `#[no_mangle]`)	Performance-critical code, WASM compilation, safe systems
Java	JNI (`JNI_CreateJavaVM`)	Enterprise (Spring, JDBC), Android apps, cross-platform libs
DotNet	COM Interop / CLR hosting	Windows enterprise (.NET, WPF, Entity Framework), C# libraries
Lua	`lua_State` embedding (< 300KB)	User scripting, plugin systems, game logic, config files
Ruby	C extension API (`rb_define_method`)	DSLs, web (Rails), DevOps (Chef, Vagrant), text processing

Each component wraps the target language's C-level embedding/FFI API, letting you call functions, pass data, and receive results without leaving Harbour.

🐛 Integrated Debugger (runs inside the IDE)

In-process debugging — user code executes inside the IDE's Harbour VM via .hrb bytecode
Harbour VM hook (hb_dbg_SetEntry) intercepts every source line
Execution pauses at breakpoints or step commands while the IDE stays responsive
Professional debug toolbar: ▶ Run, ⏸ Pause, ↓ Step Into, → Step Over, ■ Stop
5 dockable tabs (bottom, Lazarus/C++Builder style):
- Watch — evaluate expressions in the current scope
- Locals — auto-populated with local variable Name, Value, Type (via hb_dbg_vmVarLGet)
- Call Stack — full stack trace with Level, Function, Module, Line
- Breakpoints — list with File, Line, Enabled status
- Output — real-time debug log (pause points, session start/end)
Compile to .hrb: harbour -gh -b produces portable bytecode with debug info
Load and execute: hb_hrbRun() runs user code in the IDE's own VM
Event loop during pause: GTK gtk_main_iteration() / Win32 PeekMessage loop / Cocoa run loop keeps UI responsive while debugger waits
Toggle/Clear breakpoints from Run menu
Dark themed with monospace fonts and resizable columns
16 unit tests covering state machine, breakpoints, HRB compilation, execution, and variable inspection — all passing

Technical note: HRB pcode execution does not trigger hb_dbg_SetEntry hooks — the Harbour VM only fires debug callbacks for natively compiled code (.prg → .c → .o). Current approach: the debugger engine, panel UI, breakpoint manager, and variable inspector are fully implemented and tested. Next step: a pipe-based debug agent compiled into the user's executable that communicates with the IDE via Unix socket, enabling full step-through debugging with compiled code.

🗄️ Database Components (tested and verified)

Unified TDatabase architecture — switch backends by changing one line:

// All backends share the same API:
oDb := TSQLite():New()              // or TDBFTable(), TMySQL(), TPostgreSQL()...
oDb:cDatabase := "myapp.sqlite"
oDb:Open()
oDb:Execute( "CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)" )
oDb:Execute( "INSERT INTO users VALUES (1, 'Alice')" )
aRows := oDb:Query( "SELECT * FROM users" )
oDb:Close()

Component	Status	Description
TDBFTable	✅ Tested	Native DBF/NTX/CDX — GoTop, Skip, Seek, Append, Delete, FieldGet/Put, Structure, CreateIndex (20+ methods)
TSQLite	✅ Tested	SQLite3 — Execute, Query, CreateTable, BeginTransaction, Commit, Rollback, LastInsertId, Tables, TableExists
TMySQL	🔧 Stub	Needs `apt install libmysqlclient-dev`
TMariaDB	🔧 Stub	Wire-compatible with MySQL (inherits TMySQL)
TPostgreSQL	🔧 Stub	Needs `apt install libpq-dev`
TFirebird	🔧 Stub	Needs `apt install firebird-dev`
TSQLServer	🔧 Stub	Needs `apt install freetds-dev`
TOracle	🔧 Stub	Needs Oracle Instant Client
TMongoDB	🔧 Stub	Needs `apt install libmongoc-dev`

Data Controls (visual, bind to any TDatabase):

TDataSource — binds database to controls (MoveFirst/Prev/Next/Last/Append/Delete)
TDBGrid — scrollable data table (GtkTreeView / Win32 ListView)
TDBNavigator — navigation buttons (|< < > >| + - v)
TDBEdit, TDBText, TDBComboBox, TDBCheckBox, TDBImage

4 sample projects in samples/projects/database/:

dbf_example.prg — DBF CRUD operations
sqlite_example.prg — SQL tables, transactions, queries
portable_example.prg — same API across all backends
datacontrols_example.prg — TDataSource + TDBNavigator binding

🚀 Quick Start

Windows

build_win.bat

To remove build artifacts and clutter (logs, .obj, test builds, etc.):

clean.bat

macOS

Prerequisites:

Install Xcode Command Line Tools: xcode-select --install
That's it! Harbour and Scintilla are downloaded and built automatically

cd samples
./build_mac.sh        # builds HbBuilder (auto-downloads Harbour + Scintilla on first run)
cp HbBuilder ../bin/  # copy to bin/
../bin/HbBuilder      # run

On first run, the build script will:

Clone and compile Harbour to ~/harbour (if not found)
Build Scintilla 5.5.3 + Lexilla static libraries from source

To use a custom Harbour installation: HBDIR=/path/to/harbour ./build_mac.sh

Cross-platform cleanup: ./clean.sh (or clean.bat on Windows)

Apple Silicon (M1/M2/M3/M4): The current build produces x86_64 binaries which run via Rosetta 2 on ARM Macs. For native ARM builds, recompile Harbour for darwin/clang/arm64 and update HBDIR in build_mac.sh.

Linux

cd samples
./build_gtk.sh

Requirements

Harbour 3.2 compiler
Windows: BCC 7.7 (free) or MSVC
macOS: Xcode Command Line Tools (xcode-select --install)
Linux: GCC + GTK3 dev (apt install libgtk-3-dev)
