easygui a module for make easy dialogs with Tk

Reading the bucio blog at planetalinux talking about zenity that remember me the easygui module what think can be solve the same problems of zenity (or not alls ) without the gnome(gtk) deps.

python -m easygui

So with it you can make a small dirty tk gui's:

python -c "import easygui; easygui.boolbox('Are ok')"

python -c "import easygui; print easygui.ccbox('zodman continue')"

for Foresight users its packaged on fl:2-devel

sudo conary update easygui=@fl:2-devel

imageshack.us client with python powers

Im searching about the a cli what can i upload images to imageshack.us and not found on google....

So i write my own client.

#!/usr/bin/env python
import urllib2
from poster.encode import multipart_encode
from poster.streaminghttp import register_openers

API_URL = 'http://www.imageshack.us/index.php'

def yesno(x):
    if x:
        return 'yes'
    else:
        return 'no'

def upload_file(filename, optsize=None,
                user_cookie=None,
                remove_bar=True,
                tags=None,
                public=True,
                ):
    register_openers()
    data = {'fileupload' :open(filename),
            'xml':yesno(True)
            }
    datagen, headers = multipart_encode(data)

    # Some optional parameters
    if optsize:
        data['optsize'] = optsize
    if user_cookie:
        data['cookie'] = user_cookie
    if tags:
        data['tags'] = tags

    req = urllib2.Request(API_URL, datagen,headers)
    u = urllib2.urlopen(req)
    return u.read()

if __name__ == "__main__":
    import sys
    print upload_file(sys.argv[1])

the result here:

This small app. needs module poster what make the encode multipart life easy. (on foresight its on fl:2-devel xD )

Yeah it need more hack .. hackimages github repo

Update a app with conary-lib

Yeah im add a method for a simple: conary update app<=repo@tag:label>

Reading the documentation and seen some code im understand some things....

• For conary update a package ( called installing a package) need to create a Job
• With this job its a empty for begining. You must attach some task like (Update)
• If job created the update must Apply for install it.
• for update a package needs be a ChangeSpec Format:
  (troveName, (oldVersionSpec, oldFlavor), (newVersionSpec, newFlavor)
• conary.conary.ConaryClient its the base of conary Structure on Conary API.

From command line:

[zodman@cosmogirl conary-lib]$ conary q iftop
iftop was not found
[zodman@cosmogirl conary-lib]$ sudo python conarypk.py
Update Success of iftop=/zodyrepo.rpath.org@rpl:devel/0.17-3-1
[zodman@cosmogirl conary-lib]$ conary q iftop --labels
iftop=zodyrepo.rpath.org@rpl:devel/0.17-3-1

the new method:

def update(self, name, installLabel= None):
        cli = self.cli
        #get a trove
        troves = self.request_query(name, installLabel)
        for trove in troves:
            trovespec =  self.trove_to_spec( trove )
        try:
            # create a Job
            job = cli.newUpdateJob()
            # Add Update task to Job
            cli.prepareUpdateJob(job, cmdline.parseChangeList(trovespec))
            # Apply the Job
            cli.applyUpdateJob(job)
            # im rulz
            return "Update Success of %s" %  trovespec
        except NoNewTrovesError:
            return "no new Troves Found by %s " % trovespec

    def trove_to_spec(self, trove ):
        return cmdline.toTroveSpec( trove[0], str(trove[1]), None)

Using conary-lib:

    conary = ConaryPk()
    print conary.update("iftop","zodyrepo.rpath.org@rpl:devel")

conarylib using the conary public api

Doing the hacking of packagekit im reading the code from conaryBackend.py conaryFilter.py Cache.py

Im very lost following the code so im decide make more modular can i posible to do.

BTW im not found some code example or blogpost about how to use the conary public api. Im have to read the code from /usr/bin/conary file. And get some details of conary api.

Only the little help of mkj. I can do a equal of "conary q" and "conary rq"

So im decide to make a small module for basic task ( what can Improvement the packagekit) of conary api. Commands line equal with use the cli conary.

So get check the code:

pyExcelerator making xls files with python

This week ended. Im use this lib its called funny pyExcelerator ( remember me terminator movie).

Its a python module for make files compatibles with MS excel Office.

Im try it and can open files with Office 2007, Mac Office and Openoffice. This solve my problems with endusers what a need a reports in excel.

here a example:

from pyExcelerator import *

w = Workbook()
ws = w.add_sheet('Hey, Dude')

ws.write(0, 0, 1)
ws.write(1, 0, 1.23)
ws.write(2, 0, 12345678)
ws.write(3, 0, 123456.78)

ws.write(0, 1, -1)
ws.write(1, 1, -1.23)
ws.write(2, 1, -12345678)
ws.write(3, 1, -123456.78)

ws.write(0, 2, -17867868678687.0)
ws.write(1, 2, -1.23e-5)
ws.write(2, 2, -12345678.90780980)
ws.write(3, 2, -123456.78)

w.save('numbers.xls')

the better of that module its not have deps. so not need a openoffice core/lib for used it.

Django with twitter status

Im add a simple tag on django with my twitter last status. It's cached because twitter haves problems with alots of request...... so here the code

Create a templatetags on your model/ dir

import simplejson

register = Library()

@register.simple_tag
def twitter_status( username ):
    url = "http://twitter.com/statuses/user_timeline/%s.json?count=1" % username
    file  = urllib.urlopen(url)
    json_responce = file.read()
    twit = simplejson.loads(json_responce)
    return "%s" % twit[0]["text"]

Add it to my index.html page on templates

   {%load cache %}
       {% cache 18000 twitter %}
       {% load twitter %}
    <div class="twitter">

Yeap my firts time of used cache on templates. That is very similar of the code of my friend blacknash, he Implement it on blog of h1pp1e

python break the switch paradigm

Today im want to implement a pownce notes on my blog like jacobian haves.

Im really not use a switch statement on python only put a if else nodes.

So i found how python break the paradigm of switch

def link():
    print "link"
def message( ):
    print "msg"
def event(  ):
    print "event"
def file( ):
    print "juaz"
functions = {
        "link": link(),
        "message":message(),
        "event":event(),
        "file": file()
}   
dofunc = functions["event"]
dofunc()

WTF ?? where is the

switch( var ){
   case "event":
   break;
   default:
   break;
}

jira irc bot

im working on jira irc bot. This bot is for work on foresight[,-devel} channel on freenode.

The objective is interactive with jira website without visit it.

The first step is maked. Make a page for suggest, wishlist and commands request.

My plans is build a python lib for interactive first with jira and then work on the bot. The bot can based on some excelents libs like irc-lib and a repository of python bots.

Now im doing a small script for do a shorts url. Im pick http://te.tl because is smaller than http://tinyurl.com and it not used alot. So it give us a very small url.

I haved code small cli for make url on te.tl

import urllib
import re
import sys

def makeurl( url ):
    params = urllib.urlencode({'url':url,'title':''})
    f = urllib.urlopen("http://te.tl/index.php",params)
    response = f.read()
    pattern = re.compile('<h1>.*</h1>')
    m = pattern.search(response)
    if m:
        html=  m.group()
    else:
        return "Error: %s" %response
    return html.replace('<h1>','').replace('</h1>','')
print makeurl(sys.argv[1])
