logging-helpers

Basic template helpers for printing messages out to the console. Useful for debugging context in templates. Should work with any template engine.

Install

Install with npm:

$ npm install --save logging-helpers

Usage

The main export is the log helper function with other helpers decorated as properties on this function. Some apps, like assemble, verb and generate support this format. However, a non-enumberalbe toObject method is exposed for registering directly with engines like handlebars

Example:

var loggingHelpers = require('logging-helpers');
var hbs = require('handlebars');

hbs.registerHelper('log', helpers);
// register all of the other helpers
hbs.registerHelper(helpers.toObject);

Template examples

Handlebars:

{{log "%s" "this is a message"}}
{{info "%s" "this is a message"}}
{{warning "%s" "this is a message"}}
{{warn "%s" "this is a message"}}  <!-- alias for "warning" -->
{{success "%s" "this is a message"}}
{{error "%s" "this is a message"}}
{{danger "%s" "this is a message"}}  <!-- alias for "error" -->
{{ok "%s" "this is a message"}}
{{bold "%s" "this is a message"}}
{{_debug this}}
{{_inspect foo.bar}}

Lo-Dash or Underscore:

<%= log("%s", "this is a message") %>
<%= info("%s", "this is a message") %>
<%= warn("%s", "this is a message") %>
<%= warning("%s", "this is a message") %>
<%= error("%s", "this is a message") %>
<%= bold("%s", "this is a message") %>
<%= _debug(data) %>
<%= _inspect(foo.bar) %>

Verb (uses lodash-style templates, but with special delimiters to avoid delimiter collision in documentation):

{%= log("%s", "this is a message") %}
{%= info("%s", "this is a message") %}
{%= bold("%s", "this is a message") %}
{%= warn("%s", "this is a message") %}
{%= error("%s", "this is a message") %}
{%= debug(data) %}
{%= inspect(foo.bar) %}

Usage with assemble

This should work with assemble, verb, generate, update or any application based on templates.

var helpers = require('logging-helpers');
var assemble = require('assemble');
var app = assemble();
app.helpers(helpers);

You can now use the helpers like this:

{{log "%s" "this is a message"}}
{{info "%s" "this is a message"}}
{{warning "%s" "this is a message"}}
{{warn "%s" "this is a message"}}  <!-- alias for "warning" -->
{{success "%s" "this is a message"}}
{{error "%s" "this is a message"}}
{{danger "%s" "this is a message"}}  <!-- alias for "error" -->
{{ok "%s" "this is a message"}}
{{bold "%s" "this is a message"}}
{{_debug this}}
{{_inspect foo.bar}}
