Expand description
Trait that defines a buffer supporting ’ed’s base commands
Required methods
Get line tagged with given letter. Not found is error
Return the nearest previous/following index in the selection that contains the regex pattern
Set the matched flag on all lines matching given pattern
Get a line with the matched flag set, clearing that line’s flag
Mark a line with a letter, non letter chars should error
Takes a iterator over lines in strings and inserts at given index
Cut the selection from the buffer, into the clipboard
Equal to cut of selection and insert at start of selection.
Move selection to index
Moves a copy of the selection to index
Join all lines in selection into one line
Copy selected lines into clipboard
Paste the clipboard contents to given index Leave clipboard unchanged
Perform regex search and replace on the selection changing pattern.0 to pattern.1 If pattern is empty, should re-use stored pattern from previous s command Returns selection, since it may delete or add lines
Read to the buffer from given path If index is None replaces current buffer with read lines Return number of lines read
Write the buffer to given path
