It provides text processing utilities, currently focused on implementing a rope data structure for efficient string manipulation. - -- **License**: Boost Software License 1.0 -- **Repository**: https://github.com/ocl-org/tproc -- **Standard**: C++20 (required, no extensions) - -## Dependencies - -This library depends on other OCL components and Boost: - -- **OCL core libraries**: `ocl/detail/config.hpp`, `ocl/equiv.hpp`, `ocl/option.hpp`, `ocl/smart_ptr.hpp` -- **Boost libraries**: `boost/core/detail/string_view.hpp`, Boost.Test (for testing) -- The library expects Boost headers to be available (see `compile_flags.txt` for include paths) - -## Build System - -The project uses **two build systems**: - -### CMake (for installation) - -```bash -# Configure and build -cmake -B build -DINSTALL_OCL=ON -cmake --build build - -# Install headers only (header-only library) -sudo cmake --install build -``` - -- Minimum CMake version: 3.30 -- The CMake build is primarily for installing headers to the system -- Use `-DINSTALL_OCL=ON` to enable installation - -### Boost.Build (for testing) - -Tests are built using Boost.Build (b2/bjam): - -```bash -# Navigate to test directory -cd test/rope_test - -# Build and run tests -b2 - -# Run specific test -./bin/crope.test.o -``` - -- Test configuration is in `test/rope_test/Jamfile.v2` -- Tests use Boost.Test with the header-only variant (`#include <boost/test/included/unit_test.hpp>`) - -## Code Formatting - -The project uses **clang-format** with a custom Microsoft-based style: - -```bash -# Format all source files -./format.sh -``` - -**Key formatting rules** (`.clang-format`): -- **Tabs for indentation** (`UseTab: Always`) -- No column limit (`ColumnLimit: 0`) -- Pointer alignment left (`int* ptr`) -- Namespace indentation included (`NamespaceIndentation: All`) -- Aligned consecutive macros, assignments, and declarations -- File extensions formatted: `.cpp`, `.c`, `.hpp`, `.inl` - -Always run `./format.sh` before committing code changes. - -## Architecture - -### Header Organization - -``` -include/ocl/tproc.hpp # Main umbrella header -include/ocl/tproc/ - ├── rope.hpp # Public rope API (find, find_if algorithms) - └── detail/ - ├── config.hpp # Library configuration and common includes - ├── rope_fwd.hpp # basic_rope class declaration - └── rope_fwd.inl # basic_rope template implementations -``` - -### The Rope Data Structure - -The `basic_rope` class template is the core component: - -- **Template parameters**: `CharT` (character type), `Traits` (char_traits), `Allocator` -- **Type aliases**: `crope` (char), `wrope` (wchar_t), `u8rope` (char8_t, C++20), `u16rope` (char16_t, C++20) -- **Implementation pattern**: - - Declaration in `rope_fwd.hpp` - - Implementation in `rope_fwd.inl` (inline file) - - Private `tree_impl` struct for internal tree representation -- **Current state**: Basic scaffold with move semantics, but tree implementation is incomplete (stub methods return null/zero) - -### Design Patterns - -1. **Header/inline separation**: `.hpp` files contain declarations, `.inl` files contain template implementations -2. **Forward declaration pattern**: `rope_fwd.hpp` contains the class, included by `rope.hpp` which provides algorithms -3. **PIMPL-like pattern**: `tree_impl` private struct hides implementation details -4. **Move-only semantics**: Supports move construction and move assignment, tree ownership transfer - -## Development Workflow - -### Adding New Tests - -1. Create or modify test files in `test/rope_test/` -2. Update `test/rope_test/Jamfile.v2` if adding new test executables -3. Build with `b2` in the test directory -4. Tests use Boost.Test macros: `BOOST_AUTO_TEST_CASE`, `BOOST_TEST` - -### Modifying Headers - -1. **Read before editing**: All header changes require understanding the template structure -2. **Maintain declaration/implementation split**: Keep declarations in `.hpp`, implementations in `.inl` -3. **Format after changes**: Run `./format.sh` before committing -4. **Template syntax**: All template parameters must be explicitly specified (see `rope_fwd.inl` for examples) - -### Code Style Notes - -- Use tabs for indentation (enforced by clang-format) -- All source files include Boost Software License headers -- Include guards use `OCL_TPROC_*` pattern for main headers, `OCL_TPROC_*` for detail headers -- Namespace: All public API is in `ocl` or `ocl::tproc` namespace |
