• Unexpected token from webservice

  - by Kenneth B

  I got this little snippet where I call a Battlefield 3 stat server. If you visit this URL, which I'm calling, we'll be getting no errors: http://api.bf3stats.com/pc/server/?output=json&id=534f7035-cef8-48aa-b233-8d44a0956e68 But when I try to get the stats via Ajax call, I get: Uncaught SyntaxError: Unexpected token : ... In my console I can see that the response is coming in, as when I visit the url, but I can't get the data with the ajax call... Is there something wrong with my code??? $.ajax({ type: "GET", url: "http://api.bf3stats.com/pc/server/?output=json&id=534f7035-cef8-48aa-b233-8d44a0956e68", dataType: "jsonp", success: function(response) { console.log(response); } }); Thank you in advance...

• JQuery+Java setting field value with val() + single quote

  - by Fabio K

  I have a problem setting the value of a textarea element with jquery's val(). Basically, I have a JSP file which receives a string parameter called 'text'. Java code: String text = (String) request.getParameter('text'); Now I want my textarea element to receive this text: Javascript code: $('#textarea_id').val('<%=text%>'); It works when my text doesnt contain quotes single quotes (and possibly other chars). For example, for text = test' this error happens: Uncaught SyntaxError: Unexpected token ILLEGAL $('#textarea_id').val('test''); I hope you guys understand. I need a way to encode this value... i tried using escape so the quote is replaced by %27, but after unescaping its replaced again and the error happens. Thanks!

• Python: How to use code.InteractiveConsole?

  - by Rosarch

  I'm trying to use InteractiveConsole to create a new front-end for a Python interpreter. These code fragments are from me playing around with InteractiveConsole in IDLE: >>> ses = code.InteractiveConsole() >>> ses.runsource("def foo():") True >>> ses.runsource(" return 2") File "<input>", line 1 SyntaxError: 'return' outside function (<input>, line 1) False Why does it raise a syntax error? How else can I finish writing the function? Also, for something like this: >>> ses.runsource("x = 1") False >>> ses.runsource("x") 1 False How can I capture the 1 value from above? False is the return value, but 1 is written to some stream.

• How to setup prawn on heroku when installed as a git submodule

  - by brad

  I have a rails app that I am trying to deploy to heroku. This app generates pdfs using prawn. I installed prawn as a git submodule rather than as a gem as this is what is recommended on the prawn website (here). This has not worked well with heroku so far though. As stated on heroku's application constraints page submodules are not supported so I followed their instructions to track the submodule in the main project and tried again. This has not worked and when I access my application I get the following error: App failed to start An error happened during the initialization of your app. This may be due to a typo, wrong number of arguments, or calling a function that doesn’t exists. Check the stack trace below for specific details. Make sure the app is working locally in production mode, by running it with RAILS_ENV (for Rails apps) or RACK_ENV (for Sinatra or other rack apps) set to production. e.g. RAILS_ENV=production script/server. Original Error /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': /disk1/home/slugs/208590_03c9c22_67f5/mnt/app/controllers/invoices_controller.rb:37: syntax error, unexpected ')' (SyntaxError) ).to_pdf(@invoice) (and then a whole lot more that I'll spare you from) The .to_pdf function described in the last line is called in a controller in exactly the way described in the prawn how-to that I linked to above so my interpretation of the error message is that prawn is not being installed/detected. Does anyone know how I can address this? I'm new to heroku so have little idea how to approach this. Is the submodule approach for prawn dead in the water from the get-go? Do I need to install it as a gem instead. I'd rather keep it as a submodule just because that works for now and I don't want to break it.

• On Ruby on Rails, <%= or <% should only matter whether it is show or no show, but why will it give

  - by Jian Lin

  The following code: <div id="vote_form"> <%= form_remote_tag :url => story_votes_path(@story) do %> <%= submit_tag 'shove it' %> <% end %> </div> gives compilation error while if the first <%= is replaced with <%, then everything works. I thought they only differ by "show" or "not show", but why will it actually cause a compile error?

• strange syntax error in python, version 2.6 and 3.1

  - by flow

  this may not be an earth-shattering deficiency of python, but i still wonder about the rationale behind the following behavior: when i run source = """ print( 'helo' ) if __name__ == '__main__': print( 'yeah!' ) #""" print( compile( source, '<whatever>', 'exec' ) ) i get :: File "<whatever>", line 6 # ^ SyntaxError: invalid syntax i can avoid this exception by (1) deleting the trailing #; (2) deleting or outcommenting the if __name__ == '__main__':\n print( 'yeah!' ) lines; (3) add a newline to very end of the source. moreover, if i have the source end without a trailing newline right behind the print( 'yeah!' ), the source will also compile without error. i could also reproduce this behavior with python 2.6, so it’s not new to the 3k series. i find this error to be highly irritating, all the more since when i put above source inside a file and execute it directly or have it imported, no error will occur—which is the expected behavior. a # (hash) outside a string literal should always represent the start of a (possibly empty) comment in a python source; moreover, the presence or absence of a if __name__ == '__main__' clause should not change the interpretation of a soure on a syntactical level. can anyone reproduce the above problem, and/or comment on the phenomenon? cheers

• Python: Best way to check for Python version in program that uses new language features?

  - by Mark Harrison

  If I have a python script that requires at least a particular version of python, what is the correct way to fail gracefully when an earlier version of python is used to launch the script? How do I get control early enough to issue an error message and exit? For example, I have a program that uses the ternery operator (new in 2.5) and "with" blocks (new in 2.6). I wrote a simple little interpreter-version checker routine which is the first thing the script would call ... except it doesn't get that far. Instead, the script fails during python compilation, before my routines are even called. Thus the user of the script sees some very obscure synax error tracebacks - which pretty much require an expert to deduce that it is simply the case of running the wrong version of python. update I know how to check the version of python. The issue is that some syntax is illegal in older versions of python. Consider this program: import sys if sys.version_info < (2, 4): raise "must use python 2.5 or greater" else: # syntax error in 2.4, ok in 2.5 x = 1 if True else 2 print x When run under 2.4, I want this result $ ~/bin/python2.4 tern.py must use python2.5 or greater and not this result: $ ~/bin/python2.4 tern.py File "tern.py", line 5 x = 1 if True else 2 ^ SyntaxError: invalid syntax (channeling for a coworker)

• Why can't I pass an argument to create this window using wxpython?

  - by somefreakingguy

  I am trying to learn how to make a GUI in python! Following an online tutorial, I found that the following code 'works' in creating an empty window: import wx from sys import argv class bucky(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(300, 200)) if __name__=='__main__': app=wx.PySimpleApp() frame=bucky(parent=None,id=-1) frame.Show() app.MainLoop() That gives me a window, which is great. However, what if I want to get an argument passed onto the program to determine the window size? I thought something like this ought to do the trick: import wx from sys import argv script, x, y = argv class mywindow(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x, y)) if __name__=='__main__': app=wx.PySimpleApp() frame=mywindow(parent=None,id=-1) frame.Show() app.MainLoop() But, alas, that does not work! Nor does the raw_input() function pass on the value. I keep getting the following error: C:/Python26/pythonw.exe -u "C:/Documents and Settings/Owner/Desktop/wz.py" File "C:/Documents and Settings/Owner/Desktop/wz.py", line 8 wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x y)) ^ SyntaxError: invalid syntax Thanks for the help!

• Magic function `bash ` not found

  - by inspectorG4dget

  I have a bunch of simulations that I want to run on a high-performance cluster, on which I should make reservations to get computing time. Since the reservations are bounded by time, I am developing an automation script that I can scp into the cluster and run. This script will then download the relevant simulation files, run them, and upload the results. Part of this automation script is in bash (cp, scp, etc) and the rest is in python. In order to develop this automation, I am using an IPython notebook. So far, I've coded all the python automation stuff in my IPython notebook and am trying to write the bash part of it now. However, it seems that the magic %%bash doesn't work in my IPython notebook. I get the following error when I have this code in my cell: Cell %%bash echo hi Error File "<ipython-input-22-62ec98e35224>", line 3 echo hi ^ SyntaxError: invalid syntax On a whim, I tried this: Cell %%bash print "hi" Error hi ERROR: Magic function `bash` not found. So I tried this with %%system, %%! and %%shell. But none of those work; they all give me the same error. Why is this happening? How can I fix this?

• Python raw strings and trailing back slashes.

  - by dash-tom-bang

  I ran across something once upon a time and wondered if it was a Python "bug" or at least a misfeature. I'm curious if anyone knows of any justifications for this behavior. I thought of it just now reading "Code Like a Pythonista," which has been enjoyable so far. I'm only familiar with the 2.x line of Python. Raw strings are strings that are prefixed with an r. This is great because I can use backslashes in regular expressions and I don't need to double everything everywhere. It's also handy for writing throwaway scripts on Windows, so I can use backslashes there also. (I know I can also use forward slashes, but throwaway scripts often contain content cut&pasted from elsewhere in Windows.) So great! Unless, of course, you really want your string to end with a backslash. There's no way to do that in a 'raw' string. In [9]: r'\n' Out[9]: '\\n' In [10]: r'abc\n' Out[10]: 'abc\\n' In [11]: r'abc\' ------------------------------------------------ File "<ipython console>", line 1 r'abc\' ^ SyntaxError: EOL while scanning string literal In [12]: r'abc\\' Out[12]: 'abc\\\\' So one slash before the closing quote is an error, but two slashes gives you two slashes! Certainly I'm not the only one that is bothered by this? Thoughts on why 'raw' strings are 'raw, except for slash-quote'? I mean, if I wanted to embed a single quote in there I'd just use double quotes around the string, and vice versa. If I wanted both, I'd just triple quote. If I really wanted three quotes in a row in a raw string, well, I guess I'd have to deal, but is this considered "proper behavior"?

• parse xml with elementtree, custom sorting

  - by microspace

  I want to parse xml file in utf-8 and sort it by some field. Soring is made by custom alphabet (s1 from sourcecode). History of question is here: sorting of list containing utf-8 charachters. I've found how to sort xml here. Sorting work correctly, the problem is with elementtree, I must admit that it doesn't work on python3 Here is source code: #!/usr/bin/env python # -*- coding: utf-8 -*- #import xml.etree.ElementTree as ET # Python 2.5 import elementtree.ElementTree as ET s1='aáàAâÂbBcCçÇdDeéEfFgGgGhHiIîÎíiiIjJkKlLmMnNóoOöÖpPqQrRsSsStTuUûúÛüÜvVwWxXyYzZ' s2='11111122334455666aabbccddeeeeeeffgghhiijjkklllllmmnnooppqqrrsssssttuuvvwwxxyy' trans = str.maketrans(s1, s2) def unikey(seq): return seq[0].translate(trans) tree = ET.parse("tosort.xml") container = tree.find("entries") data = [] for elem in container: keyd = elem.findtext("k") data.append((keyd, elem)) print (data) data.sort(key=unikey) print (data) container[:] = [item[-1] for item in data] tree.write("sorted.xml", encoding="utf-8") Here are instructions to import elementtree module. When I import module this way :import xml.etree.ElementTree as ET, I get a message: Traceback (most recent call last): File "pcs.py", line 19, in <module> container[:] = [item[-1] for item in data] File "/usr/lib/python3.1/xml/etree/ElementTree.py", line 210, in __setitem__ assert iselement(element) AssertionError When I use this method to import: import elementtree.ElementTree as ET, I get this message: Traceback (most recent call last): File "pcs.py", line 4, in <module> import elementtree.ElementTree as ET File "/usr/local/lib/python3.1/dist-packages/elementtree/ElementTree.py", line 794, in <module> _escape = re.compile(eval(r'u"[&<>\"\u0080-\uffff]+"')) File "<string>", line 1 u"[&<>\"\u0080-\uffff]+" ^ SyntaxError: invalid syntax I use Python 3.1.3 (r313:86834, Nov 28 2010, 11:28:10).

• Rails select box in form decides on create action in controller?

  - by dannymcc

  Hi Everyone? I am trying to add a select box to the base of my create form that decides if an action runs from the controller...if that makes any sense? Basically the application creates a project in FreeagentCentral whenever a new project is made: def create @company = Company.find(params[:kase][:company_id]) @kase = @company.kases.create!(params[:kase]) respond_to do |format| params[:send_to_freeagent] ? @kase.create_freeagent_project(current_user) #flash[:notice] = 'Case was successfully created.' flash[:notice] = fading_flash_message("Case was successfully created.", 5) format.html { redirect_to(@kase) } format.xml { render :xml => @kase, :status => :created, :location => @kase } end end and within my form I have: <%= check_box_tag :send_to_freeagent, 1 % Create project in Freeagent? What I would like to happen, is if the select box is checked the project is sent to Freeagent. If not, the case just gets created locally as normal but without the Freeagent data being sent. If I use the above code, I get an exception caught error: SyntaxError in KasesController#new controllers/kases_controller.rb:114: syntax error, unexpected '\n' Any idea what I am doing wrong, also is it possible to make the check boxes checked as default? Thanks, Danny

• Modify onclick function with jQuery

  - by Chris Barr

  I've got a button that has an onclick event in it, which was set on the back end from .NET. Beside it is a checkbox <button class="img_button" onclick="if(buttonLoader(this)){WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('uxBtnRelease', '', true, '', 'somepage.aspx?oupid=5&fp=true', false, true))} return false;" type="button">Release</button> <input type="checkbox" checked="checked" id="myCheckbox"> When the checkbox is clicked, needs to change the value of the query string in the URL inside the onclick function of the button. So far I have this, and the idea is right, but I keep getting errors when it's run: "Uncaught SyntaxError: Unexpected token ILLEGAL" var defaultReleaseOnClick=null; $("#myCheckbox").click(function(){ var $releaseBtn = $(".img_button"); if(defaultReleaseOnClick==null) defaultReleaseOnClick=$releaseBtn.attr("onclick"); var newOnClickString = defaultReleaseOnClick.toString().replace(/&fp=[a-z]+'/i,"&fp="+this.checked); $releaseBtn.removeAttr("onclick").click(eval(newOnClickString)); }); I know it seems kinda hacky to convert the function to a string, do a replacement, and then try to convert it back to a function, but I don't know any other way to do it. Any ideas? I've set up a demo here: http://jsbin.com/asiwu4/edit

• Why the HelloWorld of opennlp library works fine on Java but doesn't work with Jruby?
