This change introduces a new nullStep type that can be used in place of
a nil step. This fixes an issue where multistep.If would return a nil
step if the condition was not met causing a builder to crash when
executed using `-on-error=ask` or `-on-error=abort`.
Closes#10241
* Add packer fmt command
This change adds a new command that allows users to format one or more
HCL2 Packer configuration template files.
Related to: #9174
* command/fmt: Add check flag
Packer's fmt command now supports a check flag that will output the name
of any file that would be changed by the HCL2 formatting engine. The
check flag is mutually exclusive with the write flag and will only check
if formatting is needed.
The update write flag will now overwrite the source files with the newly
formatted HCL2 source unless the `-write=false` or `-check` is passed at
the command line.
* Returns a diagnostic error if Format is unable to show a diff - equivalent to `terraform fmt`
* Updates testing to run against #Format and not the private methods of the HCL2Formatter; fixes ShowDiff test failure on Windows
* Updates comments for exported functions
* Add docs for fmt command
* handle template_dir, pwd funcs, handle min_packer_version
* gotpl packer_version becomes hcl2 packer.version
* uuid becomes hcl2 uuidv4
* test code with emojis
* handle all cases were we cannot guess what the argument was
* handle clean_resource_name cases
* up docs
* move alicloud examples from common example directory to alicloud builder
* move amazon examples to amazon builder dir
* move examples into ansible provisioner directory
* move azure examples to builder dir
* move hyperone examples into builder directory
* move jdcloud builder examples into builder directory
* move tencent cloud examples into the builder directory
* move ucloud examples into ucloud builder directory
Vagrant Cloud provides support for uploading directly to the backend
storage instead of streaming through Vagrant Cloud. This adds support
for direct to storage uploads and sets it as the default upload method.
A new option has been added to disable this behavior and revert back
to streaming upload via Vagrant Cloud (`no_direct_upload`).
This default for uploading directly to the backend storage also matches
up with changes being added to Vagrant proper for box upload behavior:
