i am trying to create a Google Chrome extension and i want it to listen to multiple keywords from the Omnibox. To make it short, i want to know whether these two things are possible:
defining multiple omnibox keywords for one extension in the manifest file
letting chrome.omnibox.onInputEntered and other events know what keyword is enabled
thanks in advance.
No, the Chromium developers have made it clear that they will not support multiple omnibox keywords for extensions:
My take on this is that an omnibox keyword is a UI surface, like a page/browser action. We limit extensions to 1 UI surface to avoid adding clutter. Given that, I don't think we should implement this.
Granted, this bug asks for both the ability to define multiple keywords and dynamically change those keywords on the fly. However, the developer response seems opposed to multiple keywords in general.
The same response suggests an alternative:
The keyword is meant to act as a prefix for your extension, so rather than having N keywords, how about 1 keyword that accepts N commands?
Instead of supporting both keyword1 something and keyword2 something, you can use masterkeyword keyword1 something and masterkeyword keyword2 something.

Let's say that I have a set of keywords that I don't want to see in my future Google search results page: {"Naruto","Toriko","One Piece","Conan"} (these are names of anime that I want to quit). Is there a way I can write a lightweight script or something so that whenever I use Google, it filters out pages containing those words? Even if I explicitly search for "Naruto", to Google the query is actually "Naruto -Naruto" so Google won't return anything. It's easy to ignore certain keywords for a single query using advanced search, but how do I ignore a set of keywords for all my queries in the future?
What is the best way to do this? A Chrome extension? A perl script? A javascript? How can I implement this feature for myself? What tools/languages should I use?
This is probably done best in your browser. For example, you could write a Firefox extension to do this. (It would probably even be worth publishing -- others may want this functionality (like parents).)
I want to extract text contents from GUI apps,here are 2 examples::
example 1:
Suppose I opened firefox, and input url : www.google.com
how can I extract the string "www.google.com" from firefox using my own app ?
example 2:
open calculator(using gcalctool),then input 1+1
How can I extract the string "1+1" of calculator from my own program?
in brief ,what I want is to find out whether there is a way to extract the text contents from any widget of an GUI application
Thanks
I don't think there's a generic way to do this, at least not a very elegant one.
Some inelegant ideas:
You might be able to modify the X window system or even some toolkit framework to extract what is being displayed in specific window elements as text.
You could take a screenshot and use an OCR library to convert the pixels back into text for the interesting areas.
You could recompile the apps of interest to add some kind of mechanism for asking them questions.
You could use something like xtest to inject events highlighting the region of interest and copying it to the clipboard.
I believe firefox and gcalctool are for examples only and you just want to know in general how to pass output of one application to other application.
There are many ways to do that on Linux, like:
piping
application1 | application2
btw here is the Firefox command line manual if you want to start firefox on Ubuntu with a URL. eg:
firefox "$url"
where $url is a variable whose value can be www.mozilla.org
That sounds difficult. Supposing you're running X11, you can very easily grab a window picture ( see "man xwd"); however there is no easy way to get to the text unless it's selected and therefore copied to the clipboard.
Alternatively, if you only want to capture user input, this is quite easy to do, too, by activation the X11 record extension: put this in your /etc/X11/xorg.conf:
Section "Module"
Load "record"
#Load other modules you need ...
EndSection
though it may prove difficult to use too, see example code for Xorg/X11 record extension fails
Does anybody know a Windows based searching tool that is easy to use and is programmer
friendly.
The functions I am looking for:
Ignore white space in search
= capable to find
myTestFunction ( $parameter, $another_parameter, $yet_another_parameter )
{ doThis();
using the query
myTestFunction($parameter,$another_parameter,$yet_another_parameter){doThis();
without Regexes.
Search code "semantically" (for me, it would have to be PHP):
Search in comments only
Search in function names only
Search for parameters that are named $xyz
Search in (insert code construct here) only
If there is none around, it's high time somebody developed it! :)
I have opened a bounty for this.
See our SD Search Engine. This is a language-sensitive search engine designed to search large code bases, with special language classifiers for C, C++, Java, C#, COBOL, JavaScript, Ada, Python, Ruby and lot of other languages, including your specific target langauge PHP (PHP4 and PHP5).
I think it does everything you requested.
It indexes the language elements so search across large code bases are extremely fast (Linux Kernal ~~ 7.5 Million lines --> 2.5 seconds). (The indexing step runs
on Windows, but the display engine is in Java.)
Search hits are shown in one-line context hit window showing the file and line number, as well as the line with the hit highlighted. Clicks on hits bring up the source code, tabs expanded appropriately, and the line count right even for languages which have odd line counting rules (such as GCC WRT form characters), with the hit line and hit text highlighted. Clicking in the source window will launch your favorite editor on the file.
Because it understands language elements, it ignores language-specific whitespace. It skips over comments unless you insist they be inspected. Searches thus ignore whitespace, comments and lineboundaries (if the language thinks lineboundaries are whitespace, which is why there are langauge-specific scanners). The query language allows you to specify which language tokens you want (specific tokens in quotes, or generic tokens such as identifiers I, numbers N, strings S, operators O and punctuation P) with constraints on the token value as well as a series of tokens.
Your example search:
myTestFunction($parameter,$another_parameter,$yet_another_parameter){doThis();
would be expressed to the search engine precisely as:
I=myTestFunction '(' I ',' I ',' I ')' '{' I=dothis '(' ')' ';'
but it would probably be easier (less typing) to find it as:
I=myTest* ... I=dothis
where I=myTest* means an identifier starting with myTest and ... means "near".
The Search Engine also offer regular expressions searches on the text, if you insist.
So you still have grep-like searches (a lot slower than indexed searches)
but with the hit window and source display windows too.
I use ack really successfully for this kind of thing, particularly when trying to find things in large codebases. I run it linux myself but I don't see any reason why it won't run on windows or in Cygwin at the very least. Check it out, I think you'll find it is exactly what you're looking for.
Search code "semantically" (for me, it would have to be PHP):
For this you could (and I think should) use some custom code using token_get_all()
See also the available tokens
Ignore white space in search
A simple regex should be sufficient. It depends on your regex-library, but most come with a whitespace modifier/flag.
For my Windows desktop search, I use Agent Ransack. I use this as a replacement for the windows search.
You can use regular expressions, but there is a nice entry screen if you want to avoid entering them directly.
Take a look at Google Desktop API, it has very powerful set of methods to do what you're looking for.
Of course it requires you to have the Google Desktop installed.
After reviewing it a little, it provides some functionality but not that specific as what you require.
I really like Crimson Editor and it allows RegEx searches. It has helped me a bunch over the past six years. I think it will fit your needs. Try it.
I use TextPad for searching code files in Windows. It has a very handy find-in-files function (Search / Find In Files) and you can use regex which should meet any search requirements. In the search results it will list the file location, line number and a snippet from that line.
Is there a way to display all functions in a C source file using vim. This feature is available with the brief editor. And this would help me a lot.
Note: This is not a programming question.
I think the Taglist plugin is what you are looking for. It shows functions, classes etc. in a sidebar and is designed to make source code browsing a lot easier.
I use this one. 0scan
You can make incremental search on all functions in the current file using tag search mechanism.
0scan is designed to perform lots of different searches. And here you can find how to search for a functions and objects in the current file.
I know the topic of removing www.experts-echange.com has been beaten to death but having to type -site:www.experts-exchange.com is tedious. Even the ability to auto add strings to a query would solve this problem. I can probably wrap this into some wget mess but this seems like basic functionality many users would base their search engine of choice on. If you have discovered some easy method to do this for yourself please let me know.
I imagine there is a really slick toolbar that feeds google your text plus the additional strings you choose. There is some internal limit to the number of words and or operators Google searches process (with good reason I suppose).
The Google Custom Search API allows you to include or exclude sites from your search. You can add a custom search engine to your iGoogle home page.

2 easy ways in Firefox:
Write a Grease Monkey script.
Use a search keyword. You type the keyword plus a string in the address bar to trigger a search. In this case the URL is http://www.google.com/search?q=-site:expertsexchange.com%20%s. To search on the site your tab is currently in, use javascript:location='http://www.google.com/search?num=100&q=site:'%20+%20escape(location.hostname)%20+%20'%20%S'%20;%20void%200
As an alternative to excluding results, I have a greasemonkey script that highlights google search results by domain. I configure subtle colors for a few sites of interest to me, like wikipedia & stackoverflow. But I use red for expertsexchange, which allows me to visually skip right over it.
I can publish my script if there is interest...
If you want to whip up your own script, you need to operate on two kinds of elements. Here are the two XPath expressions that I use:
//cite[contains(., '" + domain + "')]/ancestor::li[1]
//span[#class='a'][contains(., '" + domain + "')]/ancestor::div[#class='g']
Then I just apply background-color styles to matching elements. Pretty straight forward.
