  • snippet generation in php

    - by daniel
    Hi, I have a long chunk of text that came back from a search query. I'd like to display a snippet of the text, not the entire thing, and highlight the search query within the snippet. I realize that decided what part of the text to slice can be complicated, and I was hoping for any ideas on how do to this? Thanks!

  • Get a list/tuple/dict of the arguments passed to a function?

    - by digitala
    Given the following function: def foo(a, b, c): pass How would one obtain a list/tuple/dict/etc of the arguments passed in, without having to build the structure myself? Specifically, I'm looking for Python's version of JavaScript's arguments keyword or PHP's func_get_args() method. What I'm not looking for is a solution using *args or **kwargs; I need to specify the argument names in the function definition (to ensure they're being passed in) but within the function I want to work with them in a list- or dict-style structure.

  • How to create contexts in shoulda macros

    - by Honza
    Asking this question again with smaller code sample: # this is a dummy shoulda macro that creates a context def self.macro_context context "macro" do yield end end # i am expecting this test to fail within the macro context context "some context" do macro_context do should "test" do fail end end end So what I would expect is to see: 1) Error: test: some context macro context should test. (TestClassName) But I am getting only this: So what I would expect is to see: 1) Error: test: some context should test. (TestClassName) Any idea what am I doing wrong?

  • How can I display a manual efficiently in Sharepoint

    - by Matt Palfreman
    My organisiation uses Sharepoint for its 'intranet'. I have been given the task of creating a site for my department. One of the things I need on there is a procedure guide, which is basically a 150 page document, whereby each page is a separate procedure. Is there an efficient way within sharepoint that these procedures can be stored and searchable somehow, rather than dumping a 150 page document on there?

  • Looking for regex to extract email addresses from /etc/passwd

    - by Brent
    Most of my users have email addresses associated with their profile in /etc/passwd. They are always in the 5th field, which I can grab, but they appear at different places within a comma-separated list in the 5th field. Can somebody give me a regex to grab just the email address (delimeted by commas) from a line in this file? (I will be using grep and sed from a bash script) Sample lines from file: user1:x:1147:5005:User One,Department,,,[email protected]:/home/directory:/bin/bash user2:x:1148:5002:User Two,Department2,[email protected],:/home/directory:/bin/bash

  • Can I make ruby send network traffic over a specific iface?

    - by rjorgenson
    I am writing a script that grabs the external IP address along with some other information about each iface. I can't figure out how to make ruby send traffic over a specific iface(eth0 and wlan0 for example). I am currently using the open-uri library to open http://whatismyip.org and read it into a variable. def get_external_ip begin open("http://whatismyip.org") { |f| return f.read } rescue return "none" end end Is there any way to specify this at runtime of the script or from within the script itself(ideally)?

  • Debugging php-cli scripts with xdebug and netbeans?

    - by wurdalack
    I have managed to initiate php-cli script debug session from the IDE itself, but I need to start the debugging session from the shell / command line. These are rather complex maintenance PHP scripts which take a lot of input parameters, so entering arguments from within Netbeans is a bit cumbersome. I have done it before with Zend studio http://kb.zend.com/index.php?View=entry&EntryID=130 but now I need to get it working with Netbeans. Thanks in advance.

  • How to safely store encryption key in a .NET assembly

    - by Alex
    In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?

    In my regex, I want to say that within the sample text, any characters are allowed, including a-z in upper and lower case, numbers and special characters. For example, my regular expression may be checking that a document is html. therefore: "/[]+/" i have tried []+ but it does not seem to like this?

  • Closure Tables - Is this enough data to display a tree view?

    - by James Pitt
    Here is the table I have created by testing the closure table method. | id | parentId | childId | hops | | | | | 270 | 6 | 6 | 0 | 271 | 7 | 7 | 0 | 272 | 8 | 8 | 0 | 273 | 9 | 9 | 0 | 276 | 10 | 10 | 0 | 281 | 9 | 10 | 1 | 282 | 7 | 9 | 1 | 283 | 7 | 10 | 2 | 285 | 7 | 8 | 1 | 286 | 6 | 7 | 1 | 287 | 6 | 9 | 2 | 288 | 6 | 10 | 3 | 289 | 6 | 8 | 2 | 293 | 6 | 9 | 1 | 294 | 6 | 10 | 2 I am trying to create a simple tree of this using PHP. There does not seem to be enough data to create the table. For example, when I look purely at parentId = 6: -Part 6 -Part 7 - ? - ? -Part 9 - ? - ? We know that parts 8 and 10 exists below Part 7 or 9, but not which. We know that part 10 exists at both 3 and 4 nodes deep but where? If I look at other data in the table it is possible to tell it should be: - Part 6 - Part 7 - Part 9 - Part 10 - Part 9 - Part 10 I thought one of the benefits of closure tables was there was no need for recursive queries? Could you help explain what I am doing wrong? EDIT: For clarification, this is a mapping table. There is another table called "parts" which has a column called part_id that correlates to both the parentId and childId columns in the "closure" table. The "id" column in the table above (closure) is just for the purposes of maintaining a primary key. It is not really necessary. The methods I have used to create this closure table is described in the following article: http://dirtsimple.org/2010/11/simplest-way-to-do-tree-based-queries.html EDIT2: It can have two and three hops. I will explain easier by assigning names to the items. Part 6 = Bicycle Part 7 = Gears Part 8 = Chain Part 9 = Bolt Part 10 = Nut Nut is part of Bolt. The Bolt and Nut combo exists directly within Bicycle and within Gears which is part of Bicycle. In relation to what method to use I have looked at Adjacency, Edges, Enum Paths, Closures, DAGS(networks) and the Nested Set Model. I am still trying to work out what is what, but this is an extremely complex component database where there are multiple parents and any modification to a sub-tree must propogate through the other trees. More importantly there will be insertions, deletions and tree views that I wish to avoid recursion during general use, even at the cost of database space and query time during entry.

    I have an object of type Hash that I want to loop over via hash.each do |key, value|. I would like to get the number of times I've been through the loop starting at 1.
