Pre-release

This is a pre-release for v4.0.0 intended for testing. More changes will come before release!

(preliminary release notes follow - these will be updated for v4.0.0)

🥳 It's finally (almost) here! Welcome to gomplate v4.0.0-pre-2! This release is a (pre-release of a) major
release, with breaking changes.
Read on for more details...

Probably the most important feature that's evolved in gomplate over the years is
its support for reading and parsing data from a variety of sources. Using URLs
to specify where to find data has proven to be quite flexible, and has allowed
for a lot of different data sources to be supported.

In early 2021, I took what I had learned from supporting all of these different
data sources, and I created a new module called
go-fsimpl, which provides a
number of Go filesystem implementations that can be used with Go's filesystem
interfaces.

My goal with go-fsimpl was always to use it in gomplate, and now that it
supports most of the data sources that gomplate supports, it's time to make the
switch! As a result, and because go-fsimpl presents a much more consistent
and unified approach to data sources, I've had to drop support for one data
source, and in fixing some inconsistencies in how URLs have been handled by some
of the data sources, I've had to make some breaking changes there as well.

Please, if you're using gomplate in production, please read these release
notes carefully and in full, and review your usage of gomplate to make sure you
can adapt to these changes.

Breaking changes

Dropped support for the BoltDB data source

Support for the boltdb URL scheme has been removed. The implementation was
never very robust, and I'm not aware of anyone using it. It had some unique
quirks that would have made it quite difficult to support in go-fsiml as-is,
so I've decided to drop it.

No more slim binaries

The slim binaries were deprecated in v3.11, and will no longer be produced.

Stricter URL handling

Subpaths are now always relative URLs

When using the datasource function with a subpath (second argument), the
subpath has previously been intepreted by some data sources as a simple addition
to the URL, and by others as a relative URL to be interpreted relative to the
data source's base URL (as specified by the --datasource flag).

Now, all data sources will interpret the subpath as a relative URL, and will
resolve it relative to the data source's base URL. This means that, given a base
URL of git+https://github.com/hairyhenderson/gomplate//random and a subpath of
random.go, the resulting URL will be
git+https://github.com/hairyhenderson/gomplate//random.go. To correct this,
make sure that base URLs end with a trailing slash when the last component is a
directory.

Also, if the subpath begins with a slash, it will be interpreted as an absolute
path, and will replace the base URL's path. For example, given a base URL of
git+file:///tmp/repos//myrepo/ and a subpath of /myfile.txt, the resulting
URL will be git+file:///myfile.txt. To correct this, make sure that subpaths
don't begin with a slash. Note that for the special // separator indicating
the separation between a Git repository and the path within, a subpath should
now begin with .// rather than //.

This affects at least the git and file data sources.

Directories in datasource URLs must end with a slash

Previously, some data sources would assume URLs that end without a trailing
slash are directories, and relative lookups would be performed within that
directory. This was inconsistent with how URLs are normally interpreted, and
could lead to unexpected results.

Now, all data sources will always interpret URLs without a trailing slash as
files, and relative lookups will be performed within the parent directory of the
URL.

For example, given a base URL of vault:///secret and a subpath of foo, the
resulting URL will be vault:///foo. To correct this, make sure that base URLs
end with a trailing slash when the last component is a directory.

Consistent data values

The aws+smp data source previously returned the AWS output object, with
both metadata and data. Users needed to reference the Value field to get the
actual data. Now, the aws+smp data source will return the data directly.

The consul data source supports directory semantics, but previously returned
all the data as a JSON array of key/value pair objects. Now, the consul data
source will return directory listings like all other data sources, as a JSON
array of strings (the names of the keys).

Vault app-id auth support removed

Support for the Vault app-id auth method has been removed. This method was
deprecated in Vault 0.6.1, and removed in Vault 1.13. If you're still using this
method, you must switch to a different auth method.

Removed functions

The following functions have been removed:

  • (TODO)

Deprecations

See
the deprecation policy).

  • A number of functions are deprecated, and will likely be removed in v5:
    • the slice alias for coll.Slice (use coll.Slice instead)
    • The net.Parse* functions which produced values from the inet.af/netaddr
      module have been deprecated and replaced with functions using the Go standard
      library's net/netip package:
  • The array form of configuring nested templates is deprecated, and a new map-
    based form is now available. This will be removed in a later v4 minor release
    (i.e. not in v4.0.0, but before v5).
  • Support for the AWS_META_ENDPOINT environment variable for overriding the
    IMDS endpoint in aws functions has been deprecated in favor of the
    AWS-native AWS_EC2_METADATA_SERVICE_ENDPOINT. This will be removed in a
    later v4 minor release (i.e. not in v4.0.0, but before v5).

This is a very minor patch release to update a dependency that's causing gomplate to trigger vulnerability scanners for CVE-2022-27664.

To the best of my understanding gomplate is not vulnerable, as it doesn't expose any HTTP servers - this patch release is purely to help vulnerability scans pass!

Deprecations

I'm starting to work on gomplate v4, the next major release (with breaking
changes). In preparation for this, I'm listing some features as deprecated (see
the deprecation policy). Note that some of these may have been
deprecated for a while, but I'd like to call them out explicitly here.

  • The BoltDB
    datasource is now deprecated (see this discussion),
    and will be removed in v4.0.0.
  • The slim binaries are deprecated, and will no longer be produced starting
    with v4.0.0.
  • A number of functions are deprecated, though not all will be removed in v4:
  • The array form of configuring nested templates is deprecated, and a new map-
    based form is now available. This will be removed in v4.

Release Notes

New features and changes

  • #1422 New experimental gomplate.Renderer API is available for rendering templates programmatically. This should be of interest for developers wishing to use gomplate as a library. See the Go docs for examples.
  • #1410 Nested templates can now be referenced by URL and not just by path.
    • Notes:
      • Currently, only the file: URL scheme is supported. The full set of datasource URL schemes will be supported in a future release.
      • This also introduces a new format for the templates config option, and deprecates the previous format. See the docs for templates for more information.
  • #1402 Support for AWS IMDSv2 (EC2 instance metadata) is now available - thanks to @surki for the contribution!
  • #1358 Adding warning messages when using deprecated functions and datasources.
  • #1335 Now built with Go 1.18, which adds two new functions: break, and continue.
  • #1317 Plugins now support piping input arguments to the plugin's stdin, rather than a commandline argument. This can be configured in the config file (see the docs for details).
  • #1307 Missing directories are now automatically created for output files

New functions

Bug fixes

  • #1349 Fix bug in JSON and YAML functions where escaped forward slashes (\/) were not being correctly interpreted
