class globcursor._GlobCursor ¶
Buffer Component as memory and handler for the global cursor position on the x-axis and cursor anchors.
From here█ the cusror is moved down twice (on the y axis). line█ As long a█ the cursor is not moved on the x-axis, it will be tried to set it on the last x position.Anchors are not fully _LocalHistory compatible and will be deleted irreversibly on range removal, if there is an anchor in the range.
cursor_anchors: list[tuple[int | str, int]]
glob_column_change: bool
glob_column_val: int
add_anchor(key, anchor=None) -> None ¶
Add anchor (by default the current cursor position) under key to the memory.
The plausibility of anchor compared to the existing data is not checked
raises:
- KeyError(parameters): if the key is already assigned. The error can be processed by
add_anchor_by_err.add_anchor_by_err(error) -> None ¶
Set an anchor by the error from add_anchor.get_anchor(key) -> tuple[int | str, int] ¶
Return the anchor item with key.
raises:
- KeyError(key): if key is not present.
get_anchor_by_position(position=None) -> tuple[int | str, int] ¶
Return the anchor item with position.
raises:
- KeyError(position): if anchor with position is not present.
get_globc(__new) -> int ¶
Query the global x-position, set it to new before if flagged for change.goto_anchor(key) -> ChunkLoad ¶
Query the anchor with key and move the cursor there.
raises:
- KeyError: if key is not present.
- EOFError(0, msg): if n is not in the range of the currently loaded chunks and the chunks of the required side cannot be loaded completely/are not available.
- EOFError(1, msg): Chunks of the required side could not be loaded sufficiently. The closest chunk was loaded and the cursor was placed at the beginning of the first row.
- EOFError(2, msg): if an error occurs during the final setting of the cursor (indicator of too high value). The cursor was set to the next possible position.
- AssertionError: __local_history__ lock is engaged.
note_globc() -> None ¶
Change the global x-position on the next query.pop_anchor(key) -> tuple[int | str, int] ¶
Return the anchor item with key and pop them from cache.
raises:
- KeyError(key): if key is not present.
pop_anchor_by_position(position=None) -> tuple[int | str, int] ¶
Return the anchor item with position and pop them from cache.
raises:
- KeyError(position): if anchor with position is not present.
purge_anchors() -> list[tuple[int | str, int]] ¶
Clear and return the anchor memory.set_globc(__n) -> None ¶
Set the global x-position.
