Removes the old error handling library and switches to plain
fmt.Errorf calls.
There are several reasons for this:
* There are no useful types or handling here anyways, so output format
is the only priority.
* Users don't care about getting stacktraces.
* My emotional wellbeing.
Fin de siècle.
This is actually several refactors in one:
* rename "fileContent" function to "insertFile"
* pass the resource set path to the "insetFile" function
* update docs and example with a pipeline including indentation
adjustments for the inserted file
Adds a 'fileContent' template function to insert the literal contents
of a file specified in the template.

Pin the nixpkgs-commit used for building the Kontemplate release to a
specific commit.
Kontemplate builds should now be fully repeatable (and most likely
reproducible!) on any machine running Nix.
Adds a Nix derivation that produces statically linked output binaries
for multiple operating systems and architectures.
This requires a Nix-channel version that includes the Go 1.10
compiler.
This release comes with minor usability improvements and features.
* A new 'lookupIPAddr' template function is available for resolving
DNS A records in templates. Thanks to @landro for the pull request!
* Handling of "non-standard" resource set structures has been improved
to result in better error messages and behaviour in several places.
Release binaries are signed with GPG key `66F505681DB8F43B` which is
verified on my Github profile.
--------------
Note: This is the last Kontemplate release that will be written in Go.
Rob Pike's art project has proven its point but I believe it is
ethically questionable and morally indefensible to continue on this
path.
You can track #72 for the Rust-rewrite of Kontemplate.
Due to an interesting combination of an error not being handled and Go
initialising everything with what it thinks should be the default,
non-existent resource sets have been gracefully handled already.
This makes this accidental fix explicit.
Fixes#90
This introduces support for looking up IP addresses using local DNS resolver.
Function will return a list of all IP addresses associated with hostname.
Further processing can be achieved using supported list template functions.
After the change from #84 default variable files with the '.yml'
extension got templated as resource set templates accidentally.
This resolves the issue by moving the list reserved default file names
to a common place and reusing it in both the templater and context pkg.
This fixes#85
In other places in Kontemplate that deal with YAML files, both the
".yaml" and ".yml" extension are supported.
This fixes context loading code to support that for resource set
variables, too.
This fixes#83
This release comes with some new features, usability improvements and
a better build & release process.
Features:
* Documentation has been improved significantly, check out the new
[README][] and follow the links within!
* Extra variables can now be loaded from files on disk. Simply specify
a list of YAML/JSON files under the 'import' key in your cluster
context file. Check out #66 for details!
* Resource set paths can now be overridden by users. By default it is
assumed that the path to a resource set is the same as its name,
however this is now user-controllable.
This means the same resource set can be included multiple times
under different names, for easier including/excluding. See #71 for
details!
* Kontemplate is currently getting a website that is under construction
at [kontemplate.works][] - feel free to check it out and
[give feedback][]!
Fixes:
* Windows release binaries now have the correct filename
* Several potential warning and error messages have been improved

Instead of signing the binary and adding the signature in the release
tarball, keep the GPG-signatures *outside* of the tarball.
This makes it easier to use the built-in GPG-signature verification
features of package managers such as pacman.
Documents the structure of resource sets and the fields necessary for including
them in cluster configurations.
Also adds some words about nested resource sets and the like.
Adds documentation for `if` and `range` statements in Go templates
and also more explicitly points people at the Go documentation for
more information.
Instead of always inferring the path at which files in a resource set
are located, let users override the path by specifying a `path` field.
This makes it possible to add the same resource set multiple times
with different values while still keeping distinct names for
addressability (for example when using include/exclude).
This fixes#70
Kontemplate context specifications can now load extra variables from YAML
or JSON files by specifying a list of files (relative to the context file)
under the `import` key.
This release features some cleanup and under-the-hood changes, as well
as "ecosystem-features" that don't directly affect the way Kontemplate
itself functions.
* Resource-sets are now passed on to kubectl in individual
invocations. This means that kubectl errors can be scoped to
individual resource set files and issues such as #51 are less of a
problem.
* A Dockerfile is provided and published at `tazjin:kontemplate` on
Docker Hub. This image contains `kontemplate`, `kubectl` and `pass`
and can be used - for example - as an image for a step in a CI
system.
* Kontemplate is now available on Homebrew, check the README for
installation instructions.
* If different resource sets don't contain `---` separators in YAML,
`kubectl` calls will no longer fail. (#51)
* Autocompleted trailing slashes in shells are now filtered from
include & exclude lists to enhance the CLI experience slightly.
To prevent situations where a shell auto-appends a slash to an
include/exclude specification on the CLI, trailing slashes in those
string lists are now trimmed.
This fixes#54
Instead of passing the rendered output of all resource sets to kubectl
simultaneously, build upon the previous commit and pass resource sets
individually to new instances of kubectl.
This resolves#51
