* Pass `dirname` as extra metadata to preset constructor.
Sometimes a preset would like to know where it should resolve relative paths from (e.g. https://github.com/tleunen/babel-plugin-module-resolver) and this extra information makes that possible.
* Test for `dirname` passed into preset constructor
This adds a check for `dirname`’s existence and correctness to the
`resolve-addons-relative-to-file` test, and serves as a minimal example
of a path-aware preset.
Remove imports to lodash/assign and replace assign with Object.assign.
The lodash/assign is unnecessary for babel 7 as node >4 has the same
functionality built-in with Object.assign as used here.
This resolve the [issue 5353](https://github.com/babel/babel/issues/5353)
This encapsulates the logic for turning an acceptable preset name into
the absolute path for that preset. It can be used to preprocess a
presets list to map each preset to its absolute path, which is necessary
if `babel.transform` is going to be executed on a file outside the
directory subtree where the presets are installed.
This adds a getPossiblePresetNames helper encapsulating the logic for
what preset names we should try to resolve, and the resolvePreset method
just calls this helper and actually resolves them.
This encapsulates the logic for turning an acceptable plugin name into
the absolute path for that plugin. It can be used to preprocess a
plugins list to map each plugin to its absolute path, which is necessary
if `babel.transform` is going to be executed on a file outside the
directory subtree where the plugins are installed.
This adds a getPossiblePluginNames helper encapsulating the logic for
what plugin names we should try to resolve, and the resolvePlugin method
just calls this helper and actually resolves them.
This change ensures that when hoisting an identifier we do not hoist it up to
the first no shadowed function, but rather up to the bound shadowed function
* babel-core: add options for different parser/generator
* test for experiemental plugins, other babylon options
* fix passing options into parser
* Fix when no code is provided
* fixup tests
* fix tests again
* use filename and fallback to cwd
The filename options used by babylon is called `sourceFilename` and not `filename`. Therefore the option should be adjusted to be called `sourceFilename`.
