text_utils.hpp

1. Overview

The text_utils.hpp file provides reusable formatting, sanitization and conversion helpers.

This is an interface and data-contract file. It declares the public and internal types used by this subsystem, allowing implementation files and callers to share a stable compile-time contract.

Primary responsibilities:

  • Format sizes and offsets
  • Sanitize recovered names
  • Convert binary values to readable text
  • Support consistent UI and report output

2. File Identity and Scope

  • Source path: src/text_utils.hpp
  • Language: C++
  • File role: interface and data-contract file
  • Physical lines: 149
  • Non-empty lines: 139
  • SHA-256: 65ee7d2680256841d8424fa7c101df6699c04167676c4a60f87b147ebea5adf3

Declared namespaces:

  • text_utils

3. Dependencies

3.2 Standard and External Headers

  • cstdint
  • string

These dependencies define the file’s compile-time integration with the recovery engine, GTK interface, on-disk format decoders, operating-system services, or C++ standard library.

4. Declared Types

No class, structure, or enumeration definition is declared directly in this file.

5. Constants and Configuration Values

No preprocessor or compile-time constants were detected as top-level declarations in this file.

6. Data Members and Persistent State

The interface declares the following state-bearing members:

  • std::string out
  • std::size_t i=0
  • std::size_t expected=0
  • bool valid=true

These members hold configuration, parser context, UI widgets, source references, progress state, recovered metadata, or temporary resources according to the owning type.

7. API and Function Inventory

The following callable interfaces or definitions were detected:

  • inline std::string utf16le_to_utf8(const unsigned char*data,std::size_t byte_count) – Implements the operation identified by this API and updates or returns the associated state.
  • inline std::string sanitize_component(const std::string&in) – Implements the operation identified by this API and updates or returns the associated state.

8. Operational Flow

The subsystem represented by this file normally participates in the following flow:

  1. Format sizes and offsets.
  2. Sanitize recovered names.
  3. Convert binary values to readable text.
  4. Support consistent UI and report output.
  5. Expose or execute the detected APIs: utf16le_to_utf8, sanitize_component.
  6. Return explicit results, progress data, recovered records, or diagnostics to the calling layer.

9. Validation and Error Handling

  • Byte offsets, sizes and lengths must be validated before arithmetic and before every read to avoid overflow and out-of-bounds access.
  • Input and output paths require existence checks, permission handling and safe destination construction.

10. Runtime, Concurrency, and Resource Management

  • Deterministic behavior: callers depend on explicit return values and stable data structures to distinguish successful recovery from partial or invalid results.

11. Security and Data-Recovery Considerations

  • Recovery code should prefer read-only source access and avoid writing to the original damaged medium.
  • Raw devices and image files are treated as untrusted binary input; every offset and length must remain bounded by the source size.

12. Implementation Considerations

  • Changes to public declarations can affect every translation unit that includes this header and should preserve binary and source compatibility where required.
  • State-bearing members should have explicit ownership and initialization semantics, especially for references, pointers, file descriptors and GTK widgets.

13. Integration with the Recovery Pipeline

  • The file belongs to the source-discovery, parsing or support layer.
  • Its results feed scanner, recovery or reporting modules through shared models.
  • The API should remain deterministic so higher layers can combine results safely.

14. Licensing and Provenance

No explicit copyright or software-license statement was detected in the opening section of this individual file. Distribution terms should therefore be verified against the project-level license and repository metadata.

The SHA-256 value in this document can be used to associate the generated documentation with the exact source version analyzed.
