renderizer

renderizer

Render Go text templates from the command line.

go get github.com/gomatic/renderizer

Supports providing top-level name/value pairs on the command line:

renderizer --name=value --top=first template-file

Sets:

Name: value
Top: first

NOTE:

• Template values are provided --name=value.
• Renderizer controls are provided using -NAME[=value].

Example

First:

git clone https://github.com/gomatic/renderizer.git
cd renderizer
go build

Render the pod.yaml using values from test/.renderizer.yaml:

renderizer -S=test/.renderizer.yaml test/pod.yaml

Or set RENDERIZER in the environment:

RENDERIZER=test/.renderizer.yaml renderizer test/pod.yaml

Alternatively, it'll try .renderizer.yaml in the current directory.

(cd test; renderizer pod.yaml)

Next, override the deployment value to render the "dev" pod.yaml (after cd test/):

renderizer --deployment=dev --name='spaced out' pod.yaml

Configuration

Settings -S=

Settings can be loaded from a yaml:

renderizer -S=renderizer.yaml --name=value --top=first template-file

Capitalization -C

This is a positional toggle flag.

Variable names are converted to title case by default. It can be disabled for any subsequent variables:

renderizer --name=value -C --top=first template-file

Sets:

Name: value
top: first

Missing Keys -M=

Control the missingkeys template-engine option:

renderizer -M=zero --top=first template-file

Environment -E=

Provide a default value for missing environment variables:

renderizer -E=--missing-- template-file
