ALCDEF 2.0 to JSON converter

Meet the first ever version of ALCDEF 2.0 to JSON converter.

The main conversion points are as follows:

• All JSON keys are similar to ALCDEF field names, but in lower case.
• Boolean strings from ALCDEF are represented as booleans in JSON.
• String values from ALCDEF are partially escaped in JSON to comply with MongoDB export requirements: MongoDB compatibility was a requirement in development of the very first ALCDEF to JSON converter version. Commas are replaced with dots.
• Double strings from ALCDEF including the Julian Date are represented as doubles in JSON.
• There are two modes of data blocks conversion available: the flat mode and the nested mode. The difference between the two is as follows:
  • In the flat mode, data entries are suffixed with their index numbers.
  • In the nested mode, data entries are put into arrays, each element of such
    arrays being an object with subfields of data represented as key-value pairs.

Flags

The v1.0.0 version works with the following flags:

• --from - required, with a single argument; the argument defines the
  address of the source ALCDEF file, or directory with such files.
• --to - required, with a single argument; the argument defines the address
  of the resulting JSON file, or directory for such files; the output files
  (but not directories!) are created automatically if not exist.
• --flat - optional, with no arguments; defines the flat operation mode
  (the choices are flat and nested); default choice is nested
