Escape special characters
I’ve asked Gemini to explain it:
1. Auto-Closure (Insertion State)
When the user inputs an opening delimiter, the system immediately injects the corresponding closing delimiter and places the caret (cursor) between them.
Input: (
Buffer State: (|)
Logic: insert(openingchar) + insert(closingchar) + move_caret(-1)
2. Type-Through (Escape State)
If the caret is positioned immediately before a closing delimiter that was autopaired, and the user types that specific closing delimiter, the system suppresses the character insertion and instead advances the caret.
Context: [text|]
Input: ]
Buffer State: [text]| (Not [text]])
Logic: if (nextchar == inputchar) { movecaret(+1); preventdefault(); }
3. Atomic Deletion (Regression State)
If the caret is between an empty pair of delimiters, a backspace event deletes both the opening and closing characters simultaneously, returning the buffer to the pre-insertion state.
Context: (|)
Input: Backspace
Buffer State: |
Logic: if (prevchar == open && nextchar == close) { delete_range(caret-1, caret+1); }
4. Selection Wrapping (Transformation State)
If a text range is selected (highlighted) and an opening delimiter is typed, the system wraps the selection rather than replacing it.
Context: |selected_text|
Input: [[
Buffer State: [[selected_text]]
Logic: surroundselection(inputpair)
5. Markdown-Specific Heuristics
Obsidian applies context-aware logic for Markdown syntax (e.g., * or _). It often checks word boundaries to determine if the user intends to bold/italicize or use a bullet point.
Context (Start of line): | + * + Space -> Bullet list (autopair disabled/consumed by formatting).
Context (Middle of line): word | + * -> word | (autopair enabled for italics).
