usage

tablemark 3.0.0
> Generate markdown tables from JSON data at the command line.

ARGUMENTS:
  <input-file> - Path to input file containing JSON data (use - for stdin)

OPTIONS:
  --column <str>, -c=<str>    - Custom column name, can be used multiple times (default: infer from object keys)
  --align <value>, -a=<value> - Custom alignments, can be used multiple times, applied in order to columns (default: left)
  --line-ending, -e <str>     - End-of-line string (default: \n) [optional]
  --wrap-width, -w <number>   - Width at which to hard wrap cell content [default: Infinity]

FLAGS:
  --no-case-headers, -N   - Disable automatic sentence casing of inferred column names [default: false]
  --wrap-with-gutters, -G - Add '|' characters to wrapped rows [default: false]
  --help, -h              - show help
  --version, -v           - print the version

To apply the align and column options to multiple columns, supply the flag multiple times, like this:

tablemark input.json > output.md -a left -a center -a right

... which will align the first three columns left, center, and right respectively.

stdin

In bash-like shells:

# stdin -> stdout
echo '{ "one": 1 }' | tablemark -

# redirect input file content into stdin, then to a file
tablemark - < input.json > output.md

In PowerShell:

# stdin -> stdout
'{ "one": 1 }' | tablemark -

# redirect input file content into stdin, then to a file
cat input.json | tablemark - > output.md

ndjson

NDJSON is a form of JSON that delimits multiple JSON objects by newlines:

{"name":"trilogy","repo":"[haltcase/trilogy](https://github.com/haltcase/trilogy)","desc":"No-hassle SQLite with type-casting schema models and support for native & pure JS backends."}
{"name":"strat","repo":"[haltcase/strat](https://github.com/haltcase/strat)","desc":"Functional-ish JavaScript string formatting, with inspirations from Python."}
{"name":"tablemark-cli","repo":"[haltcase/tablemark-cli](https://github.com/haltcase/tablemark-cli)","desc":"Generate markdown tables from JSON data at the command line."}

This input from a file or stdin is supported just as if it were a JSON compatible array:

tablemark input.ndjson > output.md
