Jekyll & Liquid Cheatsheet

A list of the most common functionalities in Jekyll (Liquid). You can use Jekyll with GitHub Pages, just make sure you are using the proper version.

Running

Running a local server for testing purposes:

import pandas as pd

def _map_to_pandas(rdds):
    """ Needs to be here due to pickling issues """
    return [pd.DataFrame(list(rdds))]

def toPandas(df, n_partitions=None):
    """
    Returns the contents of `df` as a local `pandas.DataFrame` in a speedy fashion. The DataFrame is
    repartitioned if `n_partitions` is passed.

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

\%23c	Matches in a specific column. (23), example     :%s/\%1c/#/ (insert # on first column of all rows)
:% (all rows), :. (this row), :$ (last row), :.,$ (this->last row), :5,$ (5th->last row)
s, substitute. :%s/a/b/g, change all a->b on all rows.
u, undo
p, paste
m+a, set mark a [works for a-z]
'+a, go to mark a [works for a-z]
<<, de-indent row
