Vars collector and template runner.

Project description

c2c.template

Supported template Jinja, Mako, Template.

Tools that collect some vars and get them to a template engine.

Supported template: Jinja, Mako and Template.

Use c2c-template --help to get the command line help.

Vars file

The vars collector gets the vars from YAML files like this one:

extends: inherit.yaml

vars:
     string_var: a string
     int_var: 42
     interpreted_var: __import__('datetime').date.today()
     combined_var: 'Today: {interpreted_var:%Y-%m-%d}'
     facter_json: /usr/bin/facter --json
     facter_yaml: /usr/bin/facter --yaml
     pi: console.log(Math.PI.toPrecision(3))
     obj:
         v1: 1
         v2: '2'
         v3: [1, 2, 3]

 interpreted:
     python:
     - interpreted_var
     bash:
     - facter_json
     - facter_yaml
     json:
     - facter_json
     yaml:
     - facter_yaml
     node:
         vars: ["pi"]
         cmd: ["node", "-e"]

The inherit.yaml is an other file with the same syntax that will provide initial vars.

The vars section is where we define the vars values, the YAML files support typing, than 42 will be an integer.

The interpreted configuration to interpret some vars, python, bash, environ, json, yaml are predefined interpreter, node is a custom interpreter.

The combined_var reuse a predefined variable and format, See: str.format().

Example of usage

Interpret variable in a template

c2c-template --vars vars.yaml --engine jinja --files template.jinja

The result will be stored in a file named template.

Get the vars

It can be useful to get the variable outside.

`c2c-template --vars vars.yaml --get-vars INT_VAR=int_var string_var`

That will set the bash variable INT_VAR to 42, and STRING_VAR to ‘a string’.

Get a configuration file

c2c-template --vars vars.yaml --get-config config.yaml string-var int-var combined-var

Will create a file named config.yaml this:

string-var: a string
int-var: 42
combined-var: Today: 2014-12-12

Build a set of file based on a template

Create the following vars file (vars.yaml):

vars:
    var1: common
    iter:
    - name: one
      var2: first
    - name: two
      var2: second

And the following template (template.jinja):

var1: {{ var1 }}
var2: {{ var2 }}

And run the following command:

c2c-template --vars vars.yaml --files-builder template.jinja {name}.txt iter

This will create two files:

the one.txt file, with:

var1: common
var2: first

The two.txt file, with:

var1: common
var2: second
