This makes it so that when gitHead is called in a template the git hash
that is returned is the hash of the folder containing the template, not
the hash of the folder where kontemplate is called.
A template function has been added that allows one to template the
Git hash of the surrounding repo. This is useful to be able to inspect the
deployment revision of an object in Kubernetes.
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
