Implemented a static library (.lib) of classes for processing movie subtitles in C++.
The SubtitleEditor class is designed for loading, processing, and saving a sequence of subtitles. Key features include:
-
Proper Object Creation and Destruction: Implemented proper creation and destruction of
SubtitleEditorclass objects. -
Subtitle Format: The system supports a specific subtitle format that includes:
- A numerical identifier for each subtitle in the sequence.
- Timing information in the format: hours:minutes:seconds,milliseconds.
- Stylized text within the subtitles, using special markers for bold, italic, and underline styles, while ensuring no nested styles are allowed.
- Empty lines at the end of each subtitle and sequence.
-
Loading and Saving Subtitles:
- Implemented
int SubtitleEditor::loadSubtitles(string subtitles);to load subtitles, returning -1 for success or the line number of a syntax error. - Implemented
string SubtitleEditor::saveSubtitles();to return the sequence of subtitles in the specified format.
- Implemented
-
Selection and Processing of Subtitles:
- Implemented methods for selecting, deselecting, and processing subtitle selections.
- Functions to add to the selection, remove styles, and adjust timing (shift forward/backward).
-
Subtitle Styling: Implemented functions to apply and remove bold, italic, and underline styles for selected text in the subtitles.
-
Error Resolution:
- Implemented functions to fix long lines and excessive durations in subtitles, ensuring proper formatting and distribution.
-
Undo Functionality: Added the ability to undo the last change made to the subtitle sequence.
- Utilized only the
stringdata type from the Standard Library; all other data structures were implemented from scratch without using the Standard Template Library (STL), including lists and other data structures. - Managed dynamic memory properly throughout the implementation.
- Organized code into appropriate
.hand.cppfiles to maintain project structure.
