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

Windows

macOS

macOS

Linux

Linux

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.

  • 11 backend functions wrapping git.exe CLI via CreateProcess with stdout capture:
    • GIT_Status() — parses --porcelain into { { cStatus, cFile }, ... }
    • GIT_Log() — parses --format into { { cHash, cAuthor, cDate, cMsg }, ... }
    • GIT_Diff(), GIT_Blame(), GIT_CurrentBranch(), GIT_BranchList()
    • GIT_Exec() — run any git command and capture output
    • GIT_IsRepo(), GIT_RemoteList(), GIT_StashList()
  • Branch switching with list dialog (Git > Branch > Switch)
  • Dark-themed panel matching VS Code Source Control style

🔌 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.

🔍 Object Inspector

    • Windows: Scintilla.dll + Lexilla.dll (dynamic)
    • macOS: libscintilla.a + liblexilla.a (static, compiled from source)
    • Linux: libscintilla.so + liblexilla.so (dynamic)
  • VS Code Dark+ color theme with Harbour-aware syntax highlighting

  • Built-in line numbers, code folding, and indentation guides
  • Harbour-aware folding: function/return, class/endclass, if/endif, for/next, do/enddo, switch/endswitch, begin/end, #pragma begindump/enddump
  • Ctrl+F / Cmd+F Find bar, Ctrl+H / Cmd+H Replace bar
  • Ctrl+Space / Cmd+Space Auto-completion (150+ Harbour keywords, functions, xBase commands)
  • Ctrl+/ / Cmd+/ Toggle line comment
  • Ctrl+Shift+D / Cmd+Shift+D Duplicate line
  • Ctrl+Shift+K / Cmd+Shift+K Delete line
  • Ctrl+L / Cmd+L Select line
  • Ctrl+G / Cmd+G Go to line
  • F12 Go to definition (function/procedure/method/class)
  • Bracket matching — (), [], {} highlighted yellow, bad brackets red
  • Bookmarks — Cmd/Ctrl+0..9 toggle, Cmd/Ctrl+Shift+0..9 jump
  • Code snippets — Tab expansion: forn, iff, cls, func, proc, whil, swit, tryx
  • Auto-indent on Enter (preserves previous line indentation)
  • Tabbed editor (Project1.prg + Form tabs)
  • Build messages panel — clickable errors, jump to line, red markers

  • Chat interface with code suggestions
  • Also supports LM Studio (OpenAI-compatible API)
  • Future: inline code completion (Copilot-style)

🐛 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

🏗️ Architecture

Application Code (.prg)
  → xBase Commands (hbbuilder.ch — compile-time, zero cost)

🚀 Quick Start

Windows

build_win.bat

macOS

Prerequisites:

  1. Install Xcode Command Line Tools: xcode-select --install
  2. 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

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)
