This library provides Embedded Python syntax for burgled-batteries
To enable the syntax:
“‘lisp
(python.syntax:enable-python-syntax)
“‘
Python syntax is enclosed between brackets. The embedded syntax is very similar to Python’s syntax, with some differences:
* Identifiers staring with the ‘$‘ character are parsed as Lisp variable references.
* To convert the Python expression result to a Lisp object, use the ‘^‘ operator.
* Lisp expressions can be embedded in Python code, with this syntax: ‘$(<lisp expression>)‘
Example:
“‘lisp
(let (($url "http://pinterface.livejournal.com/data/atom"))
[^feedparser.parse($url)])
“‘
Some examples:
“‘lisp
(import :feedparser)
[^feedparser.parse(’http://pinterface.livejournal.com/data/atom’)]
; => #<HASH-TABLE>
“‘
To explore what is happening behind the scenes, quote the Python expression:
“‘lisp
PYTHON> ’[^.feedparser.parse(’http://pinterface.livejournal.com/data/atom’)]
(LET ((#:TRANSFORMED2520
(CFFI:CONVERT-FROM-FOREIGN
(CALL* (REF* "feedparser") "parse"
(STRING.FROM-STRING*
"http://pinterface.livejournal.com/data/atom"))
’PYTHON.CFFI::OBJECT!)))
#:TRANSFORMED2520)
“‘
Bigger example:
“‘lisp
PYTHON> (let (($cal [icalendar.Calendar()]))
[$cal.add(’prodid’, ’-//My calendar product//mxm.dk//’)]
(let (($event [icalendar.Event()]))
[$event.add(’summary’, ’Python meeting about calendaring’)]
[$event.add(’dtstart’, datetime.datetime(2005,4,4,8,0,0))]
[$event.add(’dtend’, datetime.datetime(2005,4,4,10,0,0))]
[$event.add(’dtstamp’, datetime.datetime(2005,4,4,0,10,0))]
(let (($organizer [icalendar.vCalAddress(’MAILTO: noone@example.com’)]))
[$organizer.params[’cn’] = icalendar.vText(’Max Rasmussen’)]
[$organizer.params[’role’] = icalendar.vText(’CHAIR’)]
[$event[’organizer’] = $organizer]
[$event[’location’] = icalendar.vText(’Odense, Denmark’)]
[$event[’uid’] = ’20050115T101010/27346262376@mxm.dk’]
[$event.add(’priority’, 5)]
(let (($attendee [icalendar.vCalAddress(’MAILTO:maxm@example.com’)]))
[$attendee.params[’cn’] = icalendar.vText(’Max Rasmussen’)]
[$attendee.params[’ROLE’] = icalendar.vText(’REQ-PARTICIPANT’)]
[$event.add(’attendee’, $attendee, encode=0)])
(let (($attendee [icalendar.vCalAddress(’MAILTO:the-dude@example.com’)]))
[$attendee.params[’cn’] = icalendar.vText(’The Dude’)]
[$attendee.params[’ROLE’] = icalendar.vText(’REQ-PARTICIPANT’)]
[$event.add(’attendee’, $attendee, encode=0)])
[$cal.add_component($event)]
[^$cal.to_ical()])))
