Added special variable in the for tag.

{% for item in items %}
   {{loop.index}} -- {{item}}
   {% if loop.last %}
       {{item}} is the last
   {% elif loop.first %}
        {{item}} is the first
    {% endif %}
{% endfor %}

LoopCounter()

Attributes.

loop.index

current iteration index (1 based indexing) of the loop

loop.index_0

same as loop.index, but use 0 based indexing

loop.first

Bugs fix

v0.0.5¶

This release includes critical bug fixes.

v0.0.4¶

There is no changes to this release. This release is same as v0.0.3. Released to fix a missing module on pypi release.

v0.0.3¶

Newest changes to Glass v0.0.3 .

Template¶

Fixed spaces quoted in string ('' or "") not recognized.

{% if name == '  admin  ' %}
 {% endif %}

Previously, the tag above would raise syntax error due to how glass splited tokens content. Tokens were splited with space which means quoted space(space in string ” “) would also be splited.

Previously, the above tag would yield this.

('if', 'name', '==', "'", 'admin', "'")

The above will now yield,

("if", "name","==","'  admin  '")

This is now a valid template syntax;

{% if text == 'hello word' %}
  hello word
 {% elif text == "text with space " %}
   text with space
 {% endif %}

Custom tags can use token.split_args to make use of this change.

def tag_parser(parser):
  # {% if name == '  admin  ' %}
  token = parser.get_next_token()
  args = token.split_args()
  print(args)
          #  ['name', '==', "'  admin  '"]

Added support for list indexing.

items = ['item1','item2']
render_template('test.html',items=items)

# test.html
{{items.0}} # items[0]

{{items.1}} #items[1]

Routing¶

Added url_for for url building.

from glass import GlassApp, redirect, url_for,request

app = GlassApp()

@app.route('/u/login')
def login():
      return "Hello"

@app.route('/view')
def view_name():
  user = request.user
  if not user:
    return redirect(url_for('login'))
  if not user.verify:
    path = url_for('reset_code',user=user.id,code=user.code)
    return redirect(path)

@app.route('/r/<user>/<code>')
def reset_code(user,code):
  return 'hello'

url_for is also availble in the template.

<a href='{% url_for "login" %}'>login</a>

<a href={% url_for "reset_code" user=user.id code=user.code %}> reset</a>

Other changes.

app.route now takes optional argument view_name. Which is used with url_for.

@app.route('/')
def home()
  return "hello"

To build the url for home, the function name is used.

url_for('home')

using view_name;

@app.route('/',view_name='main')
def home()
    return "hello"

url_for('main')

Other Changes

Fix function not being called in the template if it is python builtin.
Pop session flash messages if it is empty.
