This includes the machinery to recognise and transform ``%magic`` commands, ``!system`` commands, ``help?`` querying, prompt stripping, and so forth. Added: IPython 7.0.

Parameters ---------- prompt_re : regular expression A regular expression matching any input prompt (including continuation, e.g. ``...``) initial_re : regular expression, optional A regular expression matching only the initial prompt, but not continuation. If no initial expression is given, prompt_re will be used everywhere. Used mainly for plain Python prompts (``>>>``), where the continuation prompt ``...`` is a valid Python expression in Python 3, so shouldn't be stripped. Notes ----- If initial_re and prompt_re differ, only initial_re will be tested against the first line. If any prompt is found on the first two lines, prompts will be stripped from the rest of the block.

Special syntax should not be transformed when it occurs inside strings or comments. This is hard to reliably avoid with regexes. The solution is to tokenise the code as Python, and recognise the special syntax in the tokens. IPython's special syntax is not valid Python syntax, so tokenising may go wrong after the special syntax starts. These classes therefore find and transform *one* instance of special syntax at a time into regular Python syntax. After each transformation, tokens are regenerated to find the next piece of special syntax. Subclasses need to implement one class method (find) and one regular method (transform). The priority attribute can select which transformation to apply if multiple transformers match in the same place. Lower numbers have higher priority. This allows "%magic?" to be turned into a help call rather than a magic call. � c C s | j | j| jfS r )rO � start_col�priorityr+ r r r �sortby� s zTokenTransformBase.sortbyc C s |d d | _ |d | _d S r/ )rO rZ )r% rS r r r r& � s zTokenTransformBase.__init__c C s t �dS )a� Find one instance of special syntax in the provided tokens. Tokens are grouped into logical lines for convenience, so it is easy to e.g. look at the first token of each line. *tokens_by_line* is a list of lists of tokenize.TokenInfo objects. This should return an instance of its class, pointing to the start position it has found, or None if it found no match.
