Look at this very basic javascript code:
function check(a,b,c)
{
if (a[0]==a[1] && a[1]=='A' && a[2]=='C' && a.length==3)
{
console.log('Good !');
}
else
{
console.log('Wrong !');
}
}
It is easy to see the good value for 'a' parameter is 'AAC'.
Let's imagine a more complex javascript code.
What i want to do is to ask a tool to automatically resolve this kind of function.
I want to say: give me the a, b and c value that runs "Good !" Line code.
I know angr for binaries. But i am looking for a tool which works with javascript code
Thanks
I've never used it myself, but a quick google suggests this: https://github.com/ExpoSEJS/ExpoSE
I'm not sure if it does everything you need, but being open-source, it might be a good place to start. Would be great if you try it out and write up your experiences!

I want to examine http requests in an extension for firefox. To begin figuring out how to do what I want to do I figured I'd just log everything and see what comes up:
webRequest.onResponseStarted.addListener(
(stuff) => {console.log(stuff);},
{urls: [/^.*$/]}
);
The domain is insignificant, and I know the regex works, verified in the console. When running this code I get no logging. When I take out the filter parameter I get every request:
webRequest.onResponseStarted.addListener(
(stuff) => {console.log(stuff);}
);
Cool, I'm probably doing something wrong, but I can't see what.
Another approach is to manually filter on my own:
var webRequest = Components.utils.import("resource://gre/modules/WebRequest.jsm", {});
var makeRequest = function(type) {
webRequest[type].addListener(
(stuff) => {
console.log(!stuff.url.match(/google.com.*/));
if(!stuff.url.match(/google.com.*/))
return;
console.log(type);
console.log(stuff);
}
);
}
makeRequest("onBeforeRequest");
makeRequest("onBeforeSentHeaders");
makeRequest("onSendHeaders");
makeRequest("onHeadersReceived");
makeRequest("onResponseStarted");
makeRequest("onCompleted");
With the console.log above the if, I can see the regex returning true when I want it to and the code making it past the if. When I remove the console.log above the if the if no longer gets executed.
My question is then, how do I get the filtering parameter to work or if that is indeed broken, how can I get the code past the if to be executed? Obviously, this is a fire hose, and to begin searching for a solution I will need to reduce the data.
Thanks
urls must be a string or an array of match patterns. Regular expressions are not supported.
WebRequest.jsm uses resource://gre/modules/MatchPattern.jsm. Someone might get confused with the util/match-pattern add-on sdk api, which does support regular expressions.
Always feel like I'm making something far more complicated than it has to be. I'm currently playing around with the WoW addon, Tongues, in hope of make a custom dialect filter - which is quite easy of course, very noob-friendly. At this point, there is one thing I want to accomplish-- something of which feels to have the implications far beyond this -- that is just novelty, but before I give up completely (lots of hours trying different things with no headway) I was hoping someone could come by, get a cheap laugh and perhaps help me fix this if they understand my point. And who knows, posting this new helpless questions might bump me up to being able to finally upvote!
Tongues.Affect["Drunk"] = {
["substitute"] = {
[1] = merge({
{ ["([%a]+)(%A*)$"] = "%1 ...hic!"},
Tongues.Affect["Slur"]["substitute"][1]
});
};
["frequency"] = 100;
};
What this does is simply add on the "...hic!" to sendchatmessage(); I believe it is. The frequency part seems completely broken and only the GUI slider in the game matters for that. What I was hoping to accomplish was to repurpose this and make the "...hic!" an actual randomized word. Since the mod itself handles the chance that it happens, I figured all that is needed left is to replace the string with a function=X. It's, of course, intensely way over my head, but despite checking the Lua of several mods, nothing feels like "it will fit."
The best I could come up with,
Tongues.Affect["TESTAFFECT"] = {
["substitute"] = {
[1] = merge({
{ ["([%a]+)(%A*)$"] = function(b)
local rand = Math.Random(1,2)
if (rand == 1) then
b = "test1"
return b
elseif (rand == 2) then
b = "test2"
return b
end
end
Leaves a gloriously useless message in the error mod BugSack - of course my attempt is wrong, but there's no way to know how!
I'm assuming this is enough information - as I said, very user friendly mod without any need to understand how it really works (Although I'd love to ready study it after this "project")
Anyone? Regardless, thank you for your time in simply even reading this far.
Update: Downvotes, okay! That's cool too. A little unpredictable, but sure. The error is as follows
15x Tongues\Core\dialects.lua:172: attempt to index field 'Affect' (a nil value)
Tongues\Core\dialects.lua:172: in main chunk
Locals:
175 in dialects.lua is
Tongues.Affect["Wordcut"]["substitute"][1],
Which has nothing to do with what I'm trying to accomplish, and works just fine.
Sorry that my question was an inconvenience. I asked to the best of my ability and the best of my ability to articulate the question proved to be less then stellar. The example codes I had provided were the only way I could articulate showing what I was trying to do.
I was misinterpreting the error frame and discovered that behind the useless stack that calls an error where there is, in fact, none, is a stack that calls the error in syntax at the time that broke it.
I'm sharing my results, regardless if the community finds this useless. I learned a tremendous amount from this personally, which is the only incentive in that I asked for help.
Tongues.Affect["TEST"] = {
["substitute"] = {
[1] = {
["([%a]+)"] = function(a)
return a
end;
["(%A*)$"] = function(a,b)
local rand = math.random(1,2)
if (rand == 1) then
b = "test1"
return b
end;
if (rand == 2) then
b = "test2"
return b
end;
end;
};
};
};
Hope it helps someone out there - as expected, I made it more complicated than it had to be. Simply "jiggling" the symbols is all that was needed.
Just new in Prestashop (1.6.0.6), I've a problem with my product page in admin. All translatable-field are to display:none (I inspect the code with chrome).
So when I want to create a new product I can't because the name field is required.
I thought that it was simple to find the .js whose do that but it isn't.
If somebody could help me, I would be happy.
Thank you for your help
Hi,
I make some searches and see that the function hideOtherLanguage(id) hide and show translatable-field element.
function hideOtherLanguage(id)
{
console.log(id_language);
$('.translatable-field').hide();
$('.lang-' + id).show();
var id_old_language = id_language;
id_language = id;
if (id_old_language != id)
changeEmployeeLanguage();
updateCurrentText();
}
When I set the Id to 1 (default language), it works. It seems that when I load the page, the function is called twice and the last calling, the id value is undefined. So the show() function will not work.
If somebody could help me. Thank you.
In my console, I see only one error
undefined is not a function.
under index.php / Line 1002
...
$("#product_form").validate({
...
But I find the form.tpl template and set this lines in comment but nothing change.
EDIT: According to comment on this link http://forge.prestashop.com/browse/PSCFV-2928 this can possibly be caused by corrupted installation file(s) - so when on clean install - try to re-download and reinstall...
...otherwise:
I got into a similar problem - in module admin page, when creating configuration form using PrestaShop's HelperForm. I will provide most probable cases and their possible solutions.
The solution for HelperForm was tested on PS 1.6.0.14
Generally there are 2 cases when this will happen.
First, you have to check what html you recieve.
=> Display source code - NOT in developer tools/firebug/etc...!
=> I really mean the pure recieved (JavaScript untouched) html.
Check if your translatable-fields have already the inline style "display: none":
Case 1 - fields already have inline style(s) for "display: none"
This means the template/html was already prepared this way - most probably in some TPL file I saw codes similar to these:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $id_lang_default}style="display:none"{/if}>
Or particularly in HelperForm template:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $defaultFormLanguage}style="display:none"{/if}>
Case 1 is the most easy to solve, you just have to find, where to set this default language.
Solutions
HelperForm
Look where you've (or someone else) prepared the HelperForm object - something like:
$formHelper = new HelperForm();
...
Somewhere there will be something like $formHelper->default_form_language = ...;
My wrong first solution was to get default form language from context - which might not be set:
$this->context->controller->default_form_language; //THIS IS WRONG!
The correct way is to get the default language from configuration - something like:
$default_lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
$formHelper->default_form_language = $default_lang->id;
...this particularly solved my problem...
Other form-creations
If there is something else than HelperForm used for form creations, the problem is still very similar.
You have to find where in files(probably tpls) is a condition for printing display:none for your case - then find where is the check-against-variable set and set it correctly yourself.
Case 2 - fields don't have inline style(s) for "display: none"
This means it is done after loading HTML by JavaScript. There are two options:
There is a call for hideOtherLanguage(), but there is wrongly set input language - that means no language will be displayed and all hidden.Solution for this one can be often solved by solving Case 1 (see above). In addition there can be programming error in not setting the after-used language id variable at all... then you would have to set it yourself (assign in JavaScript).
Some script calls some sort of .hide() on .translatable-field - you will have to search for it the hard way and remove/comment it out.
PS: Of course you can set the language to whatever you want, it is just common to set it to default language, because it is the most easier and the most clear way how to set it.
Following on from this question on whitelisting HTML tags, I've been experimenting with Jeremy Wall's go-html-transform. In the hopes of improving searchable documentation I'm asking this here rather than pestering the author directly... hopefully this isn't too tool-specific for SO.
App Engine, latest SDK. Post.Body is a []byte. This works:
package posts
import (
// ...
"html/template"
"code.google.com/p/go-html-transform/html/transform"
"code.google.com/p/go-html-transform/h5"
)
// ...
// Pre-process post body, then return it to the template as HTML()
// to avoid html/template's escaping allowable tags
func (p *Post) BodyHTML() template.HTML {
doc, _ := transform.NewDoc(string(p.Body))
t := transform.NewTransform(doc)
// Add some text to the end of any <strong></strong> nodes.
t.Apply(transform.AppendChildren(h5.Text("<em>Foo</em>")), "strong")
return template.HTML(t.String())
}
Result:
<strong>Blarg.<em>Foo</em></strong>
However, if instead of AppendChildren() I use something like the following:
t.Apply(transform.Replace(h5.Text("<em>Foo</em>")), "strong")
I get an internal server error. Have I misunderstood the use of Replace()? The existing documentation suggests this sort of thing should be possible.
Running your transform code outside of App Engine, it panics and you can see a TODO in the source at that point. Then it's not too much harder to read the code and see that it's going to panic if given a root node.
I'm trying to get a handle on how OOP is done in Lua, and I thought I had a simple way to do it but it isn't working and I'm just not seeing the reason. Here's what I'm trying:
Person = { };
function Person:newPerson(inName)
print(inName);
p = { };
p.myName = inName;
function p:sayHello()
print ("Hello, my name is " .. self.myName);
end
return p;
end
Frank = Person.newPerson("Frank");
Frank:sayHello();
FYI, I'm working with the Corona SDK, although I am assuming that doesn't make a difference (except that's where print() comes from I believe). In any case, the part that's killing me is that inName is nil as reported by print(inName)... therefore, myName is obviously set to nil so calls to sayHello() fail (although they work fine if I hardcode a value for myName, which leads me to think the basic structure I'm trying is sound, but I've got to be missing something simple). It looks, as far as I can tell, like the value of inName is not being set when newPerson() is called, but I can't for the life of me figure out why; I don't see why it's not just like any other function call.
Any help would be appreciated. Thanks!
Remember that this:
function Person:newPerson(inName)
Is equivalent to this:
function Person.newPerson(self, inName)
Therefore, when you do this:
Person.newPerson("Frank");
You are passing one parameter to a function that expects two. You probably don't want newPerson to be created with :.
Try
Frank = Person:newPerson("Frank");
