hcl2_upgrade transforms a JSON build-file in a HCL2 build-file.
This starts a validated Packer core and from that core we generate an HCL 'block' per plugin/configuration. So for a builder, a provisioner, a post-processor or a variable. The contents of each block is just transformed as is and basically all fields are HCL2-ified.
A generated field can be valid in JSON but invalid on HCL2; for example JSON templating (in mapstructure) allows to set arrays of strings - like `x = ["a", "b"]` - with single strings - like `x="a"` -, HCL does not allow this.
Since JSON does not make the distinction between variables and locals, everything will be a variable. So variables that use other variables will not work.
hcl2_upgrade tries to transform go templating interpolation calls to HCL2 calls when possible, leaving the go templating calls like they are in case it cannot.
Work:
* transpiler
* tests
* update hcl v2 library so that output looks great.
* update docs
* Drop the iso_checksum_type & iso_checksum_url fields
In favor of simply using iso_checksum that will know what to do.
* fix after master merge
* Update builder_test.go
* Update builder_test.go
* Update builder_test.go
* Update builder_test.go
* Update builder_test.go
* remove checksum lowercasing tests
* Update builder_test.go
* Update builder_test.go
* better docs
* Update builder_test.go
* even better docs
* Update config.go
* Update builder_test.go
* Update step_create_vmx_test.go
* make generate
* better docs
* fix imports
* up tests
* Update _ISOConfig-required.html.md
* Update builder_test.go
* don't use sha1.Sum("none") as a caching path
* Update builder_test.go
* better docs
* Update iso_config_test.go
remove ISOChecksumType/ISOChecksumURL references
* Update step_download_test.go
* add iso_checksum_url and iso_checksum_type fixers + tests
* add concrete examples of checksum values
* add examples of checksumming from local file
* update go-getter dep
* up deps
* use new go-getter version
* up ESX5Driver.VerifyChecksum: use go-getter's checksumming
* ISOConfig.Prepare: get checksum there in case we need it as a string in ESX5Driver.VerifyChecksum
* Update iso_config.go
* get go-getter from v2 branch
* Update driver_esx5.go
add more comments
* Update driver_esx5.go
* show better error message when the checksum is invalid
* Update builder_test.go
put in a valid checksum to fix tests, checksum is md5("packer")
* Update builder_test.go
test invalid and valid checksum
* more test updating
* fix default md5 string to be a valid md5
* TestChecksumFileNameMixedCaseBug: use 'file:' prefix for file checksumming
* Update iso_config_test.go
* Update iso_config_test.go
* Update builder_test.go
