## SYNOPSIS

ctags … --extras=+{subparser} --languages=+iPythonCell,Python \
[--extras-IPythonCell=+{doubleSharps}] \
[--regex-IPythonCell=/<PATTERN>/\n/c/] …

## DESCRIPTION

iPythonCell parser is a subparser stacked on top of the Python parser. It works when:

- the Python parser is enabled,

- the `subparser` extra is enabled, and

- the iPythonCell parser itself is enabled.

The iPythonCell parser extracts cells explained as in vim-ipython-cell (https://github.com/hanschen/vim-ipython-cell/blob/master/README.md).

## KIND(S)

The iPythonCell parser defines only a `cell` kind.

## EXTRA(S)

Tagging cells staring with `##...` is disabled by default because the pattern is too generic; with that pattern unwanted tags can be extracted.

Enable `doubleSharps` language specific extra for tagging cells staring with `##...`.

## CUSTOMIZING

If your favorite cell pattern is not supported in the parser, you can define the pattern in your `.ctagd.d/your.ctags` or command lines. Here is an example how to support “`# CTAGS: ...`”:

“input.py”

    x=1
    # CTAGS: DEFINE F
    def F():
            # CTAGS: DO NOTING
            pass

“output.tags” with “--options=NONE --sort=no --extras=+{subparser} --regex-IPythonCell=/[ t]*# CTAGS:[ ]?(.*)$/1/c/ -o - input.py”

    x    input.py        /^x=1$/;"       v
    DEFINE F     input.py        /^# CTAGS: DEFINE F$/;" c
    F    input.py        /^def F():$/;"  f
    DO NOTING    input.py        /^      # CTAGS: DO NOTING$/;"  c

You can put “`--regex-IPythonCell=/[ \t]*# CTAGS:[ ]?(.*)$/\1/c/`” in `your.ctags` to avoid specifying the pattern repeatedly.
