Implementation Notes:

  • Used fgl unit (Free Pascal Generics Library) for type-safe collections

  • TProfileList = specialize TFPGObjectList<TProfile> provides compile-time type safety

  • FindById method uses for..in iterator (cleaner than indexed loop)

  • All string lists use Duplicates := dupIgnore to prevent duplicate defines

  • Default values set in constructors: OutputDirectory := 'target', Author := 'Unknown', License := 'Proprietary'

  • Unit compiles cleanly with FPC 3.2.2

3.2. 1.2 Configuration Loader ✅

Status: COMPLETED 2025-12-06

    • Main source file extension (.pas, .pp, .lpr)

  • Uses RegExpr unit for pattern matching

  • Tested successfully with project.xml (all profiles and defines parsed correctly)

  • Clean exception handling - frees TProjectConfig on error

3.3. 1.3 CLI Argument Parser ✅

Status: COMPLETED 2025-12-06

File: src/main/pascal/PasBuild.CLI.pas

Status Task Notes

✅

Implement ParseArguments(): TCommandLineArgs

Returns structured record with all parsed data

✅

Support goals: clean, compile, package, init

Case-insensitive matching with TBuildGoal enum

✅

Support -p <profile-id> flag parsing

Also supports --profile long form

✅

Support --help flag

Display usage instructions (also -h)

✅

Support --version flag

Show PasBuild version (also -v)

✅

Implement error handling for unknown goals

Sets ErrorMessage and ShowHelp flag

✅

Implement error handling for invalid arguments

E.g., -p without profile ID returns clear error

Deliverable: Robust argument parser with help system

Implementation Notes:

  • Type-safe goal handling using TBuildGoal enum instead of strings

  • Structured return type TCommandLineArgs record contains:

    • Goal: TBuildGoal enum value

    • ProfileId: string (empty if no profile specified)

    • ShowHelp: Boolean flag

    • ShowVersion: Boolean flag

    • ErrorMessage: string (empty if no error)

  • Case-insensitive goal matching (clean, CLEAN, Clean all work)

  • Both short and long forms supported: -p and --profile, -h and --help

  • Clean separation of concerns: parsing vs. help display vs. version display

  • Error messages guide user toward correct usage

  • All edge cases tested:

    • No arguments → shows help with error

    • Unknown goal → shows help with error

    • Missing profile ID after -p → clear error

    • Valid goals with/without profile → success

3.4. 1.4 Utility Functions ✅

Status: COMPLETED 2025-12-06

File: src/main/pascal/PasBuild.Utils.pas

Status Task Notes

✅

Implement NormalizePath(Path: string): string

Cross-platform path normalization (/ → platform separator)

✅

Implement VerifyDirectoryLayout(ProjectRoot: string): Boolean

Check if src/main/pascal/ exists

✅

Implement GetPlatformExecutableSuffix(): string

Return .exe on Windows, empty on Unix

✅

Add logging helpers: LogInfo, LogError, LogWarning

Formatted output with stderr for errors

Deliverable: Reusable utilities for file/process operations

Implementation Notes:

  • NormalizePath: Converts / to platform-specific separator (Maven convention)

    • Allows project.xml to use Unix-style paths everywhere

    • Automatically works on Windows and Unix

  • ScanForUnitPaths: Recursive directory scanner with exclusions

    • Skips: ., .., .git, .svn, backup*

    • Returns sorted, unique path list

    • Used to generate -Fu flags for FPC

  • Process Execution: Two modes

    • ExecuteProcess: Real-time output streaming (for compilation)

    • ExecuteProcessWithCapture: Capture to string (for version detection)

    • Uses /bin/sh -c on Unix, cmd.exe /c on Windows

    • Proper error handling with try/except

  • FPC Detection: Uses fpc -iV (short version) instead of deprecated -version

  • Logging: Three severity levels

    • LogInfo: Stdout with [INFO] prefix

    • LogWarning: Stdout with [WARNING] prefix

    • LogError: Stderr with [ERROR] prefix

  • No memory leaks: Verified with heap trace (-gh)

Cross-Platform Design:

Maven-inspired path handling: Users write paths with / in project.xml, and NormalizePath converts them to the correct separator for the current platform. This ensures project files work identically on Windows, Linux, and macOS.

4. Phase 2: Goal Implementation

4.1. 2.1 Clean Goal ✅

Status: COMPLETED 2025-12-06

Files: src/main/pascal/PasBuild.Command.pas, PasBuild.Command.Clean.pas

Status Task Notes

✅

Design Command Pattern architecture

TBuildCommand base class + TCommandExecutor

✅

Implement dependency resolution in executor

✅

Memory leak verification

Tested with -gh, zero leaks

Deliverable: Functional pasbuild clean command with Command Pattern

Implementation Notes:

  • Command Pattern Architecture:

    • TBuildCommand: Abstract base class for all goals

    • TCommandExecutor: Orchestrates command execution with dependency resolution

    • TBuildCommandList: Generic list of commands

    • Each goal extends TBuildCommand and implements Execute method

    • Dependencies declared via GetDependencies method

    • Executor tracks executed commands to prevent duplicates

  • Clean Command Features:

    • Deletes configured output directory (normalized for cross-platform)

    • Safety checks:

  • Only deletes if directory is under project root

  • Won’t delete project root itself

  • Won’t delete external directories

    • Gracefully handles already-clean state

    • Custom recursive delete using FindFirst/FindNext

    • No dependency on Lazarus FileUtil

  • Testing:

    • PasBuild.Test.Clean: Tests clean command in isolation

    • PasBuild.Test.Command: Tests command pattern with duplicates

    • All tests verified with heap trace (-gh flag)

    • Zero memory leaks detected

Design Benefits:

The Command Pattern provides: 1. Clean separation of concerns (each goal is independent) 2. Automatic dependency resolution (package will auto-run clean → compile) 3. Duplicate prevention (same goal won’t run twice) 4. Easy extensibility (new goals just extend TBuildCommand) 5. Testability (commands can be tested in isolation)

4.2. 2.2 Compile Goal ✅

✅

Handle FPC not found error

TUtils.IsFPCAvailable check before execution

✅

Memory leak verification

Tested with -gh, zero leaks

Deliverable: Functional pasbuild compile with profile support

Implementation Notes:

  • Command Construction (BuildCompilerCommand):

    • Base flags: -Mobjfpc -O1 (Object Pascal mode, level 1 optimization)

    • Source path: Normalized for cross-platform

    • Output flags: -FE<dir> (executable), -FU<dir> (units)

    • Executable name: -o<name> with platform suffix (.exe on Windows)

    • Unit paths: Automatically scanned from subdirectories

    • Global defines: All -d flags from config

    • Profile defines: Additional -d flags from active profile

    • Profile options: Can override optimization level and add debugging

  • Validation Flow:

    1. Check directory layout (src/main/pascal exists)

    2. Verify main source file exists

    3. Check FPC availability in PATH

    4. Create output directories

    5. Build command string

    6. Execute with real-time output

    7. Report success/failure

  • Profile Support:

    • Profile lookup by ID

    • Warning if profile not found (continues without it)

    • Profile defines merged with globals

    • Profile compiler options appended (later flags override earlier ones)

    • Example debug profile: -g -gl for debugging symbols

    • Example release profile: -O3 -CX -XX for optimization + smart linking

  • Testing:

    • Successfully compiled PasBuild itself

    • Tested without profile (default build)

    • Tested with debug profile (adds debugging flags)

    • Verified compiled binary executes correctly

    • Zero memory leaks confirmed with heap trace

Example Generated Commands:

Default build:

fpc -Mobjfpc -O1 src/main/pascal/PasBuild.pas -FEtarget -FUtarget/units -opasbuild -dUseCThreads

Debug profile:

fpc -Mobjfpc -O1 src/main/pascal/PasBuild.pas -FEtarget -FUtarget/units -opasbuild -dUseCThreads -dDEBUG -g -gl

Release profile:

fpc -Mobjfpc -O1 src/main/pascal/PasBuild.pas -FEtarget -FUtarget/units -opasbuild -dUseCThreads -dRELEASE -O3 -CX -XX

(Note: -O3 overrides earlier -O1)

4.3. 2.2.1 Main Program Integration ✅

Status: COMPLETED 2025-12-06

File: src/main/pascal/PasBuild.pas (updated)

Overview:

Integrated the Command Pattern goals into the main PasBuild program, enabling full self-hosting capability.

Changes:

  • Wired TCleanCommand and TCompileCommand into main program flow

  • Added TCommandExecutor to handle command execution

  • Proper error handling and exit code propagation

  • Memory cleanup with try/finally blocks

  • All goals now executable via command line

Main Execution Flow:

// 1. Parse command line arguments
Args := TArgumentParser.ParseArguments;

// 2. Handle --help and --version
if Args.ShowHelp then ...
if Args.ShowVersion then ...

// 3. Load project configuration
Config := TConfigLoader.LoadProjectXML('project.xml');

// 4. Create command executor
Executor := TCommandExecutor.Create;

// 5. Create appropriate command based on goal
case Args.Goal of
  bgClean: Command := TCleanCommand.Create(Config, Args.ProfileId);
  bgCompile: Command := TCompileCommand.Create(Config, Args.ProfileId);
  bgPackage: [not yet implemented]
  bgInit: [not yet implemented]
end;

// 6. Execute command with dependency resolution
ExitCode := Executor.Execute(Command);

Bootstrap Documentation:

Created BOOTSTRAP.txt with cross-platform manual compilation instructions for: * Linux * macOS * FreeBSD * Windows

The bootstrap process requires only FPC and two simple commands: 1. mkdir -p target/units 2. fpc -Mobjfpc -O1 -FEtarget -FUtarget/units -Fusrc/main/pascal src/main/pascal/PasBuild.pas

Self-Hosting Verification:

Successfully tested the following workflow:

# Bootstrap compile
mkdir -p target/units
fpc -Mobjfpc -O1 -FEtarget -FUtarget/units -Fusrc/main/pascal src/main/pascal/PasBuild.pas

# Test clean command
./target/PasBuild clean

# Rebuild using PasBuild itself (self-hosting!)
mkdir -p target/units
fpc -Mobjfpc -O1 -FEtarget -FUtarget/units -Fusrc/main/pascal src/main/pascal/PasBuild.pas
./target/PasBuild compile

# Test with profile
./target/PasBuild compile -p debug

Deliverable: PasBuild can now compile itself - full self-hosting achieved!

Implementation Notes:

  • Self-Hosting Achievement: PasBuild successfully compiles itself using the compile command

  • Memory Management: All resources properly freed in finally blocks

  • Exit Codes: Proper propagation from commands to main program

  • Error Handling: Clean error messages with appropriate exit codes

  • Profile Support: Works with both default and profile-specific builds

  • Cross-Platform: Bootstrap instructions for all major platforms

6. Phase 4: Goal Dependencies & Integration

6.1. 4.1 Goal Dependency System ✅

Status: COMPLETED 2025-12-06 (via Command Pattern)

Status Task Notes

✅

Implement goal dependency resolver

TCommandExecutor executes dependencies recursively

✅

Add dependency tracking to prevent duplicate execution

Executed commands tracked in TStringList

✅

Implement fail-fast on dependency failure

Exit immediately if dependency returns non-zero

✅

Wire package goal dependencies

TPackageCommand.GetDependencies returns clean → compile

Deliverable: Maven-like goal lifecycle

Implementation Notes:

  • Command Pattern Implementation (Phase 2.1):

    • TBuildCommand base class with GetDependencies virtual method

    • TCommandExecutor automatically resolves and executes dependencies

    • Dependency chain executed depth-first before main command

  • Duplicate Prevention:

    • Executor maintains list of executed command names

    • Command identified by GetName method

    • Skips execution if command already run: "[INFO] Goal '<name>' already executed, skipping"

  • Fail-Fast Behavior:

    • If dependency returns exit code ≠ 0, execution stops

    • Error logged: "[ERROR] Goal failed: <name>"

    • No subsequent goals execute

  • Package Goal Dependencies: pascal function TPackageCommand.GetDependencies: TBuildCommandList; begin Result := TBuildCommandList.Create(False); Result.Add(TCleanCommand.Create(Config, ProfileId)); Result.Add(TCompileCommand.Create(Config, ProfileId)); end;

  • Execution Flow for pasbuild package:

    1. Execute clean (dependency)

    2. Execute compile (dependency)

    3. Execute package (main goal)

  • ❏ Clean with custom <outputDirectory> works

Phase 2.2 (Compile):

  • ❏ pasbuild compile builds Hello World successfully

  • ❏ Executable runs and prints expected output

  • ❏ pasbuild compile -p debug activates profile defines

  • ❏ Invalid profile ID shows warning

  • ❏ Missing src/main/pascal/ shows clear error

  • ❏ Missing FPC in PATH shows clear error

  • ❏ Subdirectories generate correct -Fu flags

Phase 2.3 (Package):

  • ❏ pasbuild package creates zip archive

  • ❏ Archive contains executable + LICENSE

  • ❏ Archive name matches <name>-<version>.zip

  • ❏ Intermediate files (*.o, *.ppu) excluded

Phase 3 (Init):

  • ❏ pasbuild init creates directory structure

  • ❏ Generated project.xml is valid

  • ❏ Generated Main.pas compiles

  • ❏ pasbuild init in existing project shows error

  • ❏ Selected license file is generated correctly (BSD-3-Clause support)

  • ❏ Profile compiler options override base options correctly

Phase 4 (Integration):

  • ❏ Goal dependencies execute in correct order

  • ❏ pasbuild package runs: clean → compile → package

  • ❏ Failed dependency stops execution (fail-fast)

  • ❏ PasBuild builds itself using pasbuild compile

  • ❏ PasBuild packages itself using pasbuild package

  • ❏ --help displays all goals

  • ❏ --version shows correct versions

8.2. Automated Testing (Future)

  • ❏ Unit tests for ConfigLoader (XML parsing)

  • ❏ Unit tests for CLI argument parsing

  • ❏ Integration tests for each goal

  • ❏ Cross-platform CI pipeline (GitHub Actions)

9. Known Issues / Blockers

None currently.

(Update this section as issues arise during implementation)

10. Development Notes
