# Teeplate
A Crystal library for rendering multiple template files.
[](https://circleci.com/gh/mosop/teeplate)
## Installation
Add this to your application's `shard.yml`:
```yaml
dependencies:
teeplate:
github: mosop/teeplate
```
## Supported Template Engines
* ECR
## Usage
```crystal
require "teeplate"
```
## Example
Let's make our `crystal init` template.
#### Template structure
* spec/
* spec_helper.cr.ecr
* {{file}}_spec.cr.ecr
* src/
* {{file}}/
* version.cr.ecr
* {{file}}.cr.ecr
* .gitignore
* .travis.yml
* LICENSE.ecr
* README.md.ecr
* shard.yml.ecr
#### Template file example
```yaml
# shard.yml.ecr
name: <%= @file %>
version: 0.1.0
authors:
- <%= @author %>
license: MIT
```
#### Template class definition
```crystal
class CrystalInitTemplate < Teeplate::FileTree
directory "#{__DIR__}/path/to/template"
@file : String
@class : String
@author : String
@year : Int32
def initialize(@file, @class, @author, @year)
end
end
```
#### Here we go!
```crystal
template = CrystalInitTemplate.new("teeplate", "Teeplate", "mosop", 2016)
template.render "/path/to/output"
```
#### Output structure
* spec/
* spec_helper.cr
* teeplate_spec.cr
* src/
* teeplate/
* version.cr
* teeplate.cr
* .gitignore
* .travis.yml
* LICENSE
* README.md
* shard.yml
#### Output example
```yaml
# shard.yml
name: teeplate
version: 0.1.0
authors:
- mosop
license: MIT
```
## Overwriting
### Forced
If a file already exists, Teeplate skips rendering the file. To force overwriting, set the `:force` option:
```crystal
class Template < Teeplate::FileTree
directory "/path/to/template"
@face : String
def initialize(@face)
end
end
Template.new(":)").render("/path/to/output")
Template.new(":(").render("/path/to/output", force: true) # files may be overwritten
Template.new(":P").render("/path/to/output") # nothing happens
```
### Interactive
If the `:interactive` option is true, Teeplate prompts us to select whether to overwrite an existing file.
```
shard.yml already exists...
overwrite(o)/keep(k)/diff(d)/overwrite all(a)/keep all(n) ?
```
## Listing Rendered Files
You can print a list of rendered files. To enable it, set true to the `:list` option and call #render.
```crystal
template = BrandNewCrystalInitTemplate.new("teeplate", "Teeplate", "mosop", 2017)
template.render "/path/to/overwrite", list: true
```
Output example:
```
modified .gitignore
identical .travis.yml
new Dockerfile
skipped LICENSE
skipped README.md
skipped shard.yml
modified spec/spec_helper.cr
skipped spec/teeplate_spec.cr
skipped src/teeplate/version.cr
skipped src/teeplate.cr
```
You can colorize the output by the `:color` option.
```crystal
template.render "/path/to/overwrite", list: true, color: true
```
