dashdash - npm Package Versions

1.3.2

• Fix a subtlety where a bool option using both env and default didn't work exactly correctly. If default: false then all was fine (by luck). However, if you had an option like this:

    options: [ {
        names: ['verbose', 'v'],
        env: 'FOO_VERBOSE',
        'default': true,    // <--- this
        type: 'bool'
    } ],
  

  wanted FOO_VERBOSE=0 to make the option false, then you need the fix in this version of dashdash.

1.3.1

• [issue #1] Fix an envvar not winning over an option 'default'. Previously an option with both default and env would never take a value from the environment variable. E.g. FOO_FILE would never work here:

    options: [ {
        names: ['file', 'f'],
        env: 'FOO_FILE',
        'default': 'default.file',
        type: 'string'
    } ],
  

1.3.0

• [Backward incompatible change for boolean envvars] Change the interpretation of environment variables for boolean options to consider '0' to be false. Previous to this any value to the envvar was considered true -- which was quite misleading. Example:

    $ FOO_VERBOSE=0 node examples/foo.js
    # opts: { verbose: [ false ],
      _order: [ { key: 'verbose', value: false, from: 'env' } ],
      _args: [] }
    # args: []
  

1.2.1

• Fix for parse.help({includeEnv: true, ...}) handling to ensure that an option with an env but no help still has the "Environment: ..." output. E.g.:

    { names: ['foo'], type: 'string', env: 'FOO' }
  
    ...
  
    --foo=ARG      Environment: FOO=ARG
  

1.2.0

• Transform the option key on the opts object returned from <parser>.parse() for convenience. Currently this is just s/-/_/g, e.g. '--dry-run' -> opts.dry_run. This allow one to use hyphen in option names (common) but not have to do silly things like opt["dry-run"] to access the parsed results.

1.1.0

• Environment variable integration. Envvars can be associated with an option, then option processing will fallback to using that envvar if defined and if the option isn't specified in argv. See the "Environment variable integration" section in the README.

• Change the <parser>.parse() signature to take a single object with keys for arguments. The old signature is still supported.

• dashdash.createParser(CONFIG) alternative to new dashdash.Parser(CONFIG) a la many node-land APIs.

1.0.2

• Add "positiveInteger" and "arrayOfPositiveInteger" option types that only accept positive integers.

• Add "integer" and "arrayOfInteger" option types that accepts only integers. Note that, for better or worse, these do NOT accept: "0x42" (hex), "1e2" (with exponent) or "1.", "3.0" (floats).

1.0.1

• Fix not modifying the given option spec objects (which breaks creating a Parser with them more than once).

1.0.0

First release.
