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.

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
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
After filtering resource sets, check whether any resource sets "survived".
Otherwise it can be assumed that the user specified invalid exclude/include
combinations and should be warned about that.
Fixes#35
Golang's template package now has an option for failing if template variables
are missing: https://golang.org/pkg/text/template/#Template.Option
This updates the templater code to make use of that option and return the
errors encountered during templating.
This fixes#1
This introduces support for looking up secret values in the 'pass' command line
tool (https://www.passwordstore.org/).
Values like passwords can be interpolated from pass and even more complex
structures like certificates for Kubernetes Secrets can be retrieved and base64-
encoded as necessary.
Fixes#2
A resource set collection is a resource set with an addition 'include' array
configured. It is a short-hand for importing multiple resource sets from the
same folder and for excluding/including them as a group.
See https://github.com/tazjin/kontemplate/issues/9 for more information.
Closes#9
* renamed --limit to --include (-i)
* added --exclude (-e)
Kontemplate users can now explicitly include and exclude certain resource sets.
Excludes always override includes.
Closes#11
This adds the Go template functions from [sprig][] as well as a custom `json`
function that can interpolate any data as a JSON object - very useful for adding
arrays of data in JSON format into a variable:
```
certificateDomains:
- oslo.pub
- tazj.in
annotations:
acme/certificate: {{ .certificateDomains | json }}
annotations:
acme/certificate: ["oslo.pub", "tazj.in"]
```
[sprig]: https://godoc.org/github.com/Masterminds/sprig
Adds a basic CLI structure with a single "run" command that takes a --file (-f)
and --limit (-l) flag.
--limit can be used to only output certain resource sets.
Closes#4
