  • Clean URLs for images

    - by Albert
    I'm unable to get a working .htaccess that should accept clean URLs to load images. I mean, for example, if a user type this: http://mysite.com/image/example It works perfectly, as my PHP process and parse it. However, if the user type: .../image/example.jpg It doesn't work. I mean, if a user writes that, I want to load the module with the example.jpg as a parameter, I don't want to load the image at all! Thanks in advance.

  • How do I check mysql user have privileges like root user

    - by Devara Gudda
    I use mysql c++ wrapper in client side to connect to mysql server. When user establishes connection to mysql server I want to know whether the user have privileges like root (i.e. GRANT ALL PRIVILEGES ON . TO 'username'@'%' WITH GRANT OPTION).The 'SHOW GRANTS FOR CURRENT_USER' query gives grants for current user, but i need to parse the string and compare to know whether the current user have privileges like root. I am looking for an alternative options. Regards, Devara Gudda

  • Can parser combination be made efficient?

    - by Jon Harrop
    Around 6 years ago, I benchmarked my own parser combinators in OCaml and found that they were ~5× slower than the parser generators on offer at the time. I recently revisited this subject and benchmarked Haskell's Parsec vs a simple hand-rolled precedence climbing parser written in F# and was surprised to find the F# to be 25× faster than the Haskell. Here's the Haskell code I used to read a large mathematical expression from file, parse and evaluate it: import Control.Applicative import Text.Parsec hiding ((<|>)) expr = chainl1 term ((+) <$ char '+' <|> (-) <$ char '-') term = chainl1 fact ((*) <$ char '*' <|> div <$ char '/') fact = read <$> many1 digit <|> char '(' *> expr <* char ')' eval :: String -> Int eval = either (error . show) id . parse expr "" . filter (/= ' ') main :: IO () main = do file <- readFile "expr" putStr $ show $ eval file putStr "\n" and here's my self-contained precedence climbing parser in F#: let rec (|Expr|) (P(f, xs)) = Expr(loop (' ', f, xs)) and shift oop f op (P(g, xs)) = let h, xs = loop (op, g, xs) loop (oop, f h, xs) and loop = function | ' ' as oop, f, ('+' | '-' as op)::P(g, xs) | (' ' | '+' | '-' as oop), f, ('*' | '/' as op)::P(g, xs) | oop, f, ('^' as op)::P(g, xs) -> let h, xs = loop (op, g, xs) let op = match op with | '+' -> (+) | '-' -> (-) | '*' -> (*) | '/' -> (/) | '^' -> pown loop (oop, op f h, xs) | _, f, xs -> f, xs and (|P|) = function | '-'::P(f, xs) -> let f, xs = loop ('~', f, xs) P(-f, xs) | '('::Expr(f, ')'::xs) -> P(f, xs) | c::xs when '0' <= c && c <= '9' -> P(int(string c), xs) My impression is that even state-of-the-art parser combinators waste a lot of time back tracking. Is that correct? If so, is it possible to write parser combinators that generate state machines to obtain competitive performance or is it necessary to use code generation?

  • Live Folder: browser intent error

    - by MrSnowflake
    I'm trying to make a Live Folder with URIs. The intent I set to the Live Folder items is an Intent{Intent.ACTION_VIEW, Uri.parse(url)}. I have verified url is indeed http://www.google.com (for testing purposes). But when I click the item in the live folder I get an error message: "Application is not installed on your phone." I guess I'm missing something, but I have no idea how to make the browser launch.

  • JavaScript computer algebra system

    - by Jonas
    I am looking for a simple computer algebra system (cas) for JavaScript but I can't find anything with google. I only need basic functionality: simplify expressions to some canonic form. Ability to check if two expressions are the same, i.e., a(x+y) == ax+ay parse mathematical formulas. I want it to be able to read expressions like ax²+4x. solve simple equations etc. Do you know of such a library?

  • Git dirctet acyclic graph - children know their parents but not the other way around

    - by dayscott
    Git is implemented as a directed acyclic graph. Children know their parents but not the other way round. This makes sense because i can reach every commit only through a branch or a tag ( generally speaking through a reference). That's how i traverse the tree. What other reasons had the developers of Git to make "the children know their parents but not the other way around"?/ What are the key benefits of this?

  • Treetop: parsing single node returns nil

    - by Matchu
    I'm trying to get the basic of Treetop parsing. Here's a very simple bit of grammar so that I can say ArithmeticParser.parse('2+2').value == 4. grammar Arithmetic rule additive first:number '+' second:number { def value first.value + second.value end } end rule number [1-9] [0-9]* { def value text_value.to_i end } end end Parsing 2+2 works correctly. However, parsing 2 or 22 returns nil. What did I miss?

  • Regex for multi-line HTML comments (preg_match_all)

    - by Ben
    I have an html document with multiple commented-out PHP arrays, e.g.: <!-- Array ( [key] => 0 ) --> Using PHP, I need to somehow parse the HTML for only these comments (there are other comments that will need to be ignored) and extract the contents. I've been trying to use preg_match_all but my regex skills aren't up to much. Could anyone point me in the right direction? Any help is much appreciated!

    There are a number of questions about this sort of thing but lets imagine we are targeting a generic Linux system with both getopt and getopts installed (not that we'll use either, but they seem popular) How do I parse both long (--example | --example simple-option) and short argruments (-e | -esimple-example | -e simple-example)

  • "This Friday" in bash script

    - by Ben
    Hi, Is there a way to calculate a time stamp for the next coming up of a week day? So for instance, with friday, i'd like to be able to run some code that calculates that from today Wednesday 19/05/10, the next friday will be 21/05/10 and get a time stamp from it. I know the date command can parse a given string date according to a format, but I can't figure out how to calculate "next friday from today" Any idea? Cheers Ben

  • How can I append a description to a Zend_Form_Element?

    - by Mallika Iyer
    I have the following Zend_Form_Element: $imginstructions = "Some description"; $img = $this->createElement('select','img'); $img->setAttrib('class', 'image-select'); $imgdecorator = $img->getDecorator('Description'); $imgdecorator->setOption('escape', false); $img->setLabel('Image:') ->setRequired(true) ->addMultiOptions($images) ->setValue('') ->setDescription($imginstructions) ->addErrorMessage('You must select an image'); $img->size = 5; $this->addElement($img); The description should appear next to the select box. The problem is : When an error is thrown, the html rendered changes so the description shows up below the select box, instead of beside it. HTML rendered before error is thrown: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <p class="description">Some Description</p></dd> HTML rendered after error is thrown: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <ul class="errors"><li>You must select an image</li></ul> <p class="description">Some Description</p></dd> Is there a way to force the error message to be appended as the last element in the DOM tree for the dd element? Something like: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <p class="description">Some Description</p> <ul class="errors"><li>You must select an image</li></ul></dd> so the 'ul' is at the end of the dd DOM tree. Thanks, I appreciate your taking the time to respond to this question!

  • How to properly read 16 byte unsigned integer with BinaryReader

    - by Brent
    I need to parse a binary stream in .NET to convert a 16 byte unsigned integer. I would like to use the BinaryReader.ReadUIntXX() functions but there isn't a BinaryReader.ReadUInt128() function available. I assume I will have to roll my own function using the ReadByte function and build an array but I don't know if this is the most efficient method? Thanks!

  • How can I convert data encoded in WE8MSWIN1252 to utf8 for use in Python scripts?

    - by James Dean
    This data comes from an Oracle database and is extracted to flatfiles in encoding 'WE8MSWIN1252'. I want to parse the data and do some analysis. I want to see the text fields but do not need to publish the results to any other system so if some characters do not get converted perfectly I do not have a problem with that. I just do not want my parsing to fail with a decode error which is what I get if I use: inputFile = codecs.open( dataFileName, "r", "utf-8'")
