Recipes

• Create a markdown formatted table of Ramda's functions
• Merge JSON files into a single object
• Unwrap a list of objects into Line Delimited JSON
• Read filenames from stdin as an object of {filename: body}
• Inspect MongoDB collection as a table

Create a markdown formatted table of Ramda's functions

npm install -g markdown-table-cli
curl -s https://raine.github.io/ramda-json-docs/latest.json | \
  R 'project <[ name sig category ]>' \
    'map evolve sig: (-> it and "`#it`"), name: -> "[`#it`](http://ramdajs.com/docs/##it)"' \
  | md-table

name	sig	category
add	Number -> Number -> Number	Math
adjust	(a -> a) -> Number -> [a] -> [a]	List
always	a -> (* -> a)	Function
aperture	Number -> [a] -> [[a]]	List

Merge JSON files into a single object

cat *.json | R --slurp merge-all

Unwrap a list of objects into Line Delimited JSON

cat data.json | R --unslurp --compact identity

Read filenames from stdin as an object of {filename: body}

find . -name '*.txt' | R -r --slurp 'map -> (it): read-file it' merge-all

Inspect MongoDB collection as a table

Install flat to $HOME/node_modules, which is useful for flattening deep structures into a shallow object.

mongoexport -d test -c zips --jsonArray -q '{state: "NY"}' --sort '{pop: -1}' |\
  R 'map require \flat' -o table | less

Data: http://media.mongodb.org/zips.json

The result looks something like this:
