# node-dashdash changelog
|
|
|
|
## not yet released
|
|
|
|
(nothing yet)
|
|
|
|
## 1.14.1
|
|
|
|
- [issue #30] Change the output used by dashdash's Bash completion support to
|
|
indicate "there are no completions for this argument" to cope with different
|
|
sorting rules on different Bash/platforms. For example:
|
|
|
|
$ triton -v -p test2 package get <TAB> # before
|
|
##-no -tritonpackage- completions-##
|
|
|
|
$ triton -v -p test2 package get <TAB> # after
|
|
##-no-completion- -results-##
|
|
|
|
## 1.14.0
|
|
|
|
- New `synopsisFromOpt(<option spec>)` function. This will be used by
|
|
[node-cmdln](https://github.com/trentm/node-cmdln) to put together a synopsis
|
|
of options for a command. Some examples:
|
|
|
|
> synopsisFromOpt({names: ['help', 'h'], type: 'bool'});
|
|
'[ --help | -h ]'
|
|
> synopsisFromOpt({name: 'file', type: 'string', helpArg: 'FILE'});
|
|
'[ --file=FILE ]'
|
|
|
|
|
|
## 1.13.1
|
|
|
|
- [issue #20] `bashCompletionSpecFromOptions` breaks on an options array with
|
|
an empty-string group.
|
|
|
|
|
|
## 1.13.0
|
|
|
|
- Update assert-plus dep to 1.x to get recent fixes (particularly for
|
|
`assert.optional*`).
|
|
|
|
- Drop testing (and official support in packages.json#engines) for node 0.8.x.
|
|
Add testing against node 5.x and 4.x with `make testall`.
|
|
|
|
- [pull #16] Change the `positiveInteger` type to NOT accept zero (0).
|
|
For those who might need the old behaviour, see
|
|
"examples/custom-option-intGteZero.js". (By Dave Pacheco.)
|
|
|
|
|
|
## 1.12.2
|
|
|
|
- Bash completion: Add `argtypes` to specify the types of positional args.
|
|
E.g. this would allow you to have an `ssh` command with `argtypes = ['host',
|
|
'cmd']` for bash completion. You then have to provide Bash functions to
|
|
handle completing those types via the `specExtra` arg. See
|
|
"[examples/ddcompletion.js](examples/ddcompletion.js)" for an example.
|
|
|
|
- Bash completion: Tweak so that options or only offered as completions when
|
|
there is a leading '-'. E.g. `mytool <TAB>` does NOT offer options, `mytool
|
|
-<TAB>` *does*. Without this, a tool with options would never be able to
|
|
fallback to Bash's "default" completion. For example `ls <TAB>` wouldn't
|
|
result in filename completion. Now it will.
|
|
|
|
- Bash completion: A workaround for not being able to explicitly have *no*
|
|
completion results. Because dashdash's completion uses `complete -o default`,
|
|
we fallback to Bash's "default" completion (typically for filename
|
|
completion). Before this change, an attempt to explicitly say "there are
|
|
no completions that match" would unintentionally trigger filename completion.
|
|
Instead as a workaround we return:
|
|
|
|
$ ddcompletion --none <TAB> # the 'none' argtype
|
|
##-no completions-##
|
|
|
|
$ ddcompletion # a custom 'fruit' argtype
|
|
apple banana orange
|
|
$ ddcompletion z
|
|
##-no -fruit- completions-##
|
|
|
|
This is a bit of a hack, but IMO a better experience than the surprise
|
|
of matching a local filename beginning with 'z', which isn't, in this
|
|
case, a "fruit".
|
|
|
|
## 1.12.1
|
|
|
|
- Bash completion: Document `<option spec>.completionType`. Add `includeHidden`
|
|
option to `bashCompletionSpecFromOptions()`. Add support for dealing with
|
|
hidden subcmds.
|
|
|
|
|
|
## 1.12.0
|
|
|
|
- Support for generating Bash completion files. See the "Bash completion"
|
|
section of the README.md and "examples/ddcompletion.js" for an example.
|
|
|
|
|
|
## 1.11.0
|
|
|
|
- Add the `arrayFlatten` boolean option to `dashdash.addOptionType` used for
|
|
custom option types. This allows one to create an `arrayOf...` option type
|
|
where each usage of the option can return multiple results. For example:
|
|
|
|
node mytool.js --foo a,b --foo c
|
|
|
|
We could define an option type for `--foo` such that
|
|
`opts.foo = ['a', 'b', 'c']`. See
|
|
"[examples/custom-option-arrayOfCommaSepString.js](examples/custom-option-arrayOfCommaSepString.js)"
|
|
for an example.
|
|
|
|
|
|
## 1.10.1
|
|
|
|
- Trim the published package to the minimal bits. Before: 24K tarball, 144K unpacked.
|
|
After: 12K tarball, 48K unpacked. `npm` won't let me drop the README.md. :)
|
|
|
|
|
|
## 1.10.0
|
|
|
|
- [issue #9] Support `includeDefault` in help config (similar to `includeEnv`) to have a
|
|
note of an option's default value, if any, in help output.
|
|
- [issue #11] Fix option group breakage introduced in v1.9.0.
|
|
|
|
|
|
## 1.9.0
|
|
|
|
- [issue #10] Custom option types added with `addOptionType` can specify a
|
|
"default" value. See "examples/custom-option-fruit.js".
|
|
|
|
|
|
## 1.8.0
|
|
|
|
- Support `hidden: true` in an option spec to have help output exclude this
|
|
option.
|
|
|
|
|
|
## 1.7.3
|
|
|
|
- [issue #8] Fix parsing of a short option group when one of the
|
|
option takes an argument. For example, consider `tail` with
|
|
a `-f` boolean option and a `-n` option that takes a number
|
|
argument. This should parse:
|
|
|
|
tail -fn5
|
|
|
|
Before this change, that would not parse correctly.
|
|
It is suspected that this was introduced in version 1.4.0
|
|
(with commit 656fa8bc71c372ebddad0a7026bd71611e2ec99a).
|
|
|
|
|
|
## 1.7.2
|
|
|
|
- Known issues: #8
|
|
|
|
- Exclude 'tools/' dir in packages published to npm.
|
|
|
|
|
|
## 1.7.1
|
|
|
|
- Known issues: #8
|
|
|
|
- Support an option group *empty string* value:
|
|
|
|
...
|
|
{ group: '' },
|
|
...
|
|
|
|
to render as a blank line in option help. This can help separate loosely
|
|
related sets of options without resorting to a title for option groups.
|
|
|
|
|
|
## 1.7.0
|
|
|
|
- Known issues: #8
|
|
|
|
- [pull #7] Support for `<parser>.help({helpWrap: false, ...})` option to be able
|
|
to fully control the formatting for option help (by Patrick Mooney) `helpWrap:
|
|
false` can also be set on individual options in the option objects, e.g.:
|
|
|
|
var options = [
|
|
{
|
|
names: ['foo'],
|
|
type: 'string',
|
|
helpWrap: false,
|
|
help: 'long help with\n newlines' +
|
|
'\n spaces\n and such\nwill render correctly'
|
|
},
|
|
...
|
|
];
|
|
|
|
|
|
## 1.6.0
|
|
|
|
- Known issues: #8
|
|
|
|
- [pull #6] Support headings between groups of options (by Joshua M. Clulow)
|
|
so that this code:
|
|
|
|
var options = [
|
|
{ group: 'Armament Options' },
|
|
{ names: [ 'weapon', 'w' ], type: 'string' },
|
|
{ group: 'General Options' },
|
|
{ names: [ 'help', 'h' ], type: 'bool' }
|
|
];
|
|
...
|
|
|
|
will give you this help output:
|
|
|
|
...
|
|
Armament Options:
|
|
-w, --weapon
|
|
|
|
General Options:
|
|
-h, --help
|
|
...
|
|
|
|
|
|
## 1.5.0
|
|
|
|
- Known issues: #8
|
|
|
|
- Add support for adding custom option types. "examples/custom-option-duration.js"
|
|
shows an example adding a "duration" option type.
|
|
|
|
$ node custom-option-duration.js -t 1h
|
|
duration: 3600000 ms
|
|
$ node custom-option-duration.js -t 1s
|
|
duration: 1000 ms
|
|
$ node custom-option-duration.js -t 5d
|
|
duration: 432000000 ms
|
|
$ node custom-option-duration.js -t bogus
|
|
custom-option-duration.js: error: arg for "-t" is not a valid duration: "bogus"
|
|
|
|
A custom option type is added via:
|
|
|
|
var dashdash = require('dashdash');
|
|
dashdash.addOptionType({
|
|
name: '...',
|
|
takesArg: true,
|
|
helpArg: '...',
|
|
parseArg: function (option, optstr, arg) {
|
|
...
|
|
}
|
|
});
|
|
|
|
- [issue #4] Add `date` and `arrayOfDate` option types. They accept these date
|
|
formats: epoch second times (e.g. 1396031701) and ISO 8601 format:
|
|
`YYYY-MM-DD[THH:MM:SS[.sss][Z]]` (e.g. "2014-03-28",
|
|
"2014-03-28T18:35:01.489Z"). See "examples/date.js" for an example usage.
|
|
|
|
$ node examples/date.js -s 2014-01-01 -e $(date +%s)
|
|
start at 2014-01-01T00:00:00.000Z
|
|
end at 2014-03-29T04:26:18.000Z
|
|
|
|
|
|
## 1.4.0
|
|
|
|
- Known issues: #8
|
|
|
|
- [pull #2, pull #3] Add a `allowUnknown: true` option on `createParser` to
|
|
allow unknown options to be passed through as `opts._args` instead of parsing
|
|
throwing an exception (by https://github.com/isaacs).
|
|
|
|
See 'allowUnknown' in the README for a subtle caveat.
|
|
|
|
|
|
## 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.
|
