  • How match 'other' applications to a tag in awesome-wm?

    - by Mnementh
    I use version 3.3.4 of awesome and it is fine. But I miss one thing I could do with an older version of awesome (without configuration via Lua): I could add a matcher with the regexp .* to add all windows without another tag to a specific tag: rule { name = ".*" tags = "9" } With that all applications I didn't made another rule for were added to tag 9. How can I do something similar with configuration in rc.lua?

  • How to match a string in URI with regular expression?

    - by forestclown
    In my Apache config httpd.conf, I wish to setup a rule like below SetEnvIfNoCase %{QUERY_STRING} ^.*(getBook+)$ no-gzip dont-vary I am hoping to do no-gzip when my URL looks like http://myurl.fake.com/book/getBook3?id=234 http://myurl.fake.com/book/getBook1?id=xxx I am not sure if I can do that by setting up something like the above in httpd.conf.. The reason I do query string is because the url myurl.fake.com/book/getBook3 was mod_rewrite from myurl.fake.com/index.php?controller=book&action=getBook3 Thanks!

  • Apache mod_proxy_html Substitute: how to re-use part of regex match? (regex variables?)

    - by goober
    Hi all, Have a unique URL-rewriting situation in Apache. I need to be able to take a URL that starts with "\u002f[X]" or '\u002f[X]" Where X is the rest of some URL, and substitute the text "\u002fmeis2\u002f[X] I'm not sure how the Regex works in Apache -- I think it's the same as Perl 5? -- but even then I'm a little unsure how this would be done. My hunch is that it has to do with Regex grouping and then using $1 to pull the variable out, but I'm entirely unfamiliar with this process in Apache. Hoping someone can help -- thanks!

  • Windows XP: Make Google Chrome's minimize, restore and close buttons match other programs?

    - by TRiG
    I like the way Google Chrome puts the tabs above the address bar, but I don't like the way the minimize, restore, close buttons are a different shape to every other program's. It means that if I sit the mouse in the top corner and minimize everything, I find that I've restored Chrome, not minimized it. Is there any way to get these buttons to a normal shape and size? That's Firefox in front, looking normal, like every other program, and Chrome above and behind, with the buttons at an off-standard position and size.

  • How do I get ftype & assoc to match Windows Explorer?

    - by Gauthier
    I changed the association to use upon launching a .py file, via Windows Explorer: Tools - Folders - File types. Then browse to .py. Change the association to Wordpad. Now when I type the name of a py file in the command line, Wordpad opens it. But assoc and ftype in the command line still return the following: C:\> assoc .py .py = Python.File C:\> ftype Python.File Python.File = "C:\Program\Python27\python.exe" "%1" %* How come the association is working, but assoc and ftype are not aware of it? I did restart the prompt. More info from my registry: HKEY_CLASSES_ROOT\.py = Python.File HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\Application = wordpad.exe HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\OpenWithProgids\Python.File = HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.py\(Standard) = Python.File More registry: HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command\(Standard) = "C:\Program\Python27\python.exe" "%1" %*` I suppose this is what is showing up in ftype Python.File. But it does not seem to get used. (I am doing this for testing, so I can eventually choose my default version of Python easily).

  • Google Analytics recording event based on <a> title attribute

    - by rlsaj
    I am declaring: var title = (typeof(el.attr('title')) != 'undefined' ) ? el.attr('title') :""; and then have the following: else if (title.match(/^"Matching Content"\:/i)) { elEv.category = "Matching Content Click"; elEv.action = "click-Matching-Content"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } However, using Google Analytics debugger this is not being recorded. Any suggestions? The complete function is: if (typeof jQuery != 'undefined') { jQuery(document).ready(function gLinkTracking($) { var filetypes = /\.(avi|csv|dat|dmg|doc.*|exe|flv|gif|jpg|mov|mp3|mp4|msi|pdf|png|ppt.*|rar|swf|txt|wav|wma|wmv|xls.*|zip)$/i; var baseHref = ''; if (jQuery('base').attr('href') != undefined) baseHref = jQuery('base').attr('href'); jQuery('a').on('click', function (event) { var el = jQuery(this); var track = true; var href = (typeof(el.attr('href')) != 'undefined' ) ? el.attr('href') :""; var title = (typeof(el.attr('title')) != 'undefined' ) ? el.attr('title') :""; var isThisDomain = href.match(document.domain.split('.').reverse()[1] + '.' + document.domain.split('.').reverse()[0]); if (!href.match(/^javascript:/i)) { var elEv = []; elEv.value=0, elEv.non_i=false; if (href.match(/^mailto\:/i)) { elEv.category = "Email link"; elEv.action = "click-email"; elEv.label = href.replace(/^mailto\:/i, ''); elEv.loc = href; } else if (title.match(/^"Matching Content"\:/i)) { elEv.category = "Matching Content Click"; elEv.action = "click-Matching-Content"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } else if (href.match(filetypes)) { var extension = (/[.]/.exec(href)) ? /[^.]+$/.exec(href) : undefined; elEv.category = "File Downloaded"; elEv.action = "click-" + extension[0]; elEv.label = href.replace(/ /g,"-"); elEv.loc = baseHref + href; } else if (href.match(/^https?\:/i) && !isThisDomain) { elEv.category = "External link"; elEv.action = "click-external"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } else if (href.match(/^tel\:/i)) { elEv.category = "Telephone link"; elEv.action = "click-telephone"; elEv.label = href.replace(/^tel\:/i, ''); elEv.loc = href; } else track = false; if (track) { _gaq.push(['_trackEvent', elEv.category.toLowerCase(), elEv.action.toLowerCase(), elEv.label.toLowerCase(), elEv.value, elEv.non_i]); if ( el.attr('target') == undefined || el.attr('target').toLowerCase() != '_blank') { setTimeout(function() { location.href = elEv.loc; }, 400); return false; } } } }); }); }

  • How can I check for a string match AND an empty file in the same if/then bash script statement?

    - by Mike B
    I'm writing a simple bash script to do the following: 1) Check two files (foo1 and foo2). 2) If foo1 is different from foo2 and foo1 NOT blank, send an email. 3) If foo1 is the same as foo2... or foo1 is blank... do nothing. The blank condition is what's confusing me. Here's what I've got to start with: diff --brief <(sort ./foo1) <(sort ./foo2) >/dev/null comp_value=$? if [ $comp_value -ne 0 ] then mail -s "Alert" [email protected] <./alertfoo fi Obviously this doesn't check for blank contents. Any thoughts on how to do that?

  • Are there web search engines with exact match or regex capabilities (for related terms)?

    - by naxa
    Every once in a while I come upon a situation when google's way of searching results in too broad results even if I enclose my search terms in quotation marks. For example now I've tried to find pages that contain both "py.path" and "path.py" without much success. I'm currently aware of engines|sites like Google Code Search for searching actual code and (apparently) Stackoverflow for searching QAs, symbolhound that lets me find symbols, and also wikipedia is often a good place to find lists of symbols. But none of these seems to perform very good in matching exactly on search term pairs (or tuples) and use a broad-enough segment of the web. Is there a website that is good with exactly finding search term pairs? (Why not?)

  • How to make ssh match known_hosts to host/ip:port instead of just host/ip?

    - by Prody
    I have two machines behind a firewall, with the ssh ports forwarded to 2201 and 2202. When I ssh host -p 2201 it asks if I trust the machine, I say yes, it gets added to ~/.ssh/known_hosts Then I ssh host -p 2202 it doesn't let me, because there's already a known_host for this IP in ~/.ssh/known_host:1 (the file was empty when I started, so line 1 is the one added by the previous ssh run) This happens on CentOS 5.4. On other distros (I've tried Arch), it appears that ssh matches the knwown_hosts to the ports too, so I can have multiple fingerprints for multiple ports on the same host/ip without any problems. How can I get this same behavior for CentOS? I couldn't find anything in man ssh_config. (or at least not without disabling fingerprint checking)

  • How do I recursively delete all files or folders whose names match a pattern in Windows?

    - by zylstra
    For the file example, I would like to delete all files matching .+?[a-f0-9]{4}.html (i.e. any html file ending in a four digit hexadecimal). So paged47c.html would be deleted, but page.html would remain. For the folder example, I would like to delete all folders matching .+?[A-Z]+ (i.e. any folder containing a capital letter). So some-folderSE93_89ds/ would be deleted, but some-folder/ would remain. I don't work much with the command line, but I could probably get an example involving "del" to work for me. Alternatively, is there a simple GUI program for Windows that would do this?

  • SQL INSTR() using CSV. Need exact match rather than part

    - by Alastair Pitts
    This is a follow up issue relating to the answer for http://stackoverflow.com/questions/2445029/sql-placeholder-in-where-in-issue-inserted-strings-fail Quick background: We have a SQL query that uses a placeholder value to accept a string, which represents a unique tag/id. Usually, this is only a single tag, but we needed the ability to use a csv string for multiple tags, returning a combined result. In the answer we received from the vendor, they suggested the use of the INSTR function, ala: select * from pitotal where tag IN (SELECT tag from pipoint WHERE INSTR(?, tag) <> 0) and time between 'y' and 't' This works perfectly well 99% of the time, the issue is when the tag is also a subset of 2 parts of the CSV string. Eg the placeholder value is: 'northdom,southdom,eastdom,westdom' and possible tags include: north or northdom What happens, as north is a subset of northdom, is that the two tags are return instead of just northdom, which is actually what we want. I'm not strong on SQL so I couldn't work out how to set it as exact, or split the csv string, so help would be appreciated. Is there a way to split the csv string or make it look for an exact match?

  • How do I match complete XML objects in a string?

    - by cyclotis04
    I'm attempting to find complete XML objects in a string. They have been placed in the string by an XmlSerializer, but may or may not be complete. I've toyed with the idea of using a regular expression, because it seems like the kind of thing they were built for, except for the fact that I'm trying to parse XML. I'm trying to find complete objects in the form: <?xml version="1.0"?> <type> <field>value</field> ... </type> My thought was a regex to find <?xml version="1.0"?><type> and </type>, but if a field has the same name as type, it obviously won't work. There's plenty of documentation on XML parsers, but they seem to all need a complete, fully-formed document to parse. My XML objects can be in a string surrounded by pretty much anything else (including other complete objects). hw<e>reR@lot$0fr@ndm&nchrs%<?xml version="1.0"?><type><field>...</field>...</type>@ndH#r$omOre!!>nuT6erjc?y!<?xml version="1.0"?><type><field>...</field>...</type>ty!=] A regex would be able to match a string while excluding the random characters, but not find a complete XML object. I'd like some way to extract an object, parse it with a serializer, then repeat until the string contains no more valid objects.

  • what is a RoR best practice? match by id or different column?

    - by Omnipresent
    I had a terrible morning. Lots of emails floating around about why things don't work. Upon investigating I found that there is a data mismatch which is causing errors. Scenario Customer and Address are two tables. Customer contains class Customer < ActiveRecord::Base has_one :address, :foreign_key => "id" end Address Contains class Address < ActiveRecord::Base belongs_to :customer, :foreign_key => "cid" end So the two tables match on id which is the default and that column is auto incremented. Problem on the edit Page we have some code like this. params[:line1] = @customer.first.address.line1 It fails because no matching record is found for a customer in the address table. I don't know why this is happening. It seems that over time a lot of records did not get added to Address table. Now problem is that when a new Customer is added (say with id 500) the Address will be added with some other id (say 425) ...now you don't know which address belongs to which customer. Question Being new to Rails, I am asking whether it is always considered good to create an extra column for joining of the records, rather than depending on the column that is automatically incremented? If I had a seperate column in Address table where I would manually insert the recently added customers id then this issue would not have come up.

  • Same query has nested loops when used with INSERT, but Hash Match without.

    - by AaronLS
    I have two tables, one has about 1500 records and the other has about 300000 child records. About a 1:200 ratio. I stage the parent table to a staging table, SomeParentTable_Staging, and then I stage all of it's child records, but I only want the ones that are related to the records I staged in the parent table. So I use the below query to perform this staging by joining with the parent tables staged data. --Stage child records INSERT INTO [dbo].[SomeChildTable_Staging] ([SomeChildTableId] ,[SomeParentTableId] ,SomeData1 ,SomeData2 ,SomeData3 ,SomeData4 ) SELECT [SomeChildTableId] ,D.[SomeParentTableId] ,SomeData1 ,SomeData2 ,SomeData3 ,SomeData4 FROM [dbo].[SomeChildTable] D INNER JOIN dbo.SomeParentTable_Staging I ON D.SomeParentTableID = I.SomeParentTableID; The execution plan indicates that the tables are being joined with a Nested Loop. When I run just the select portion of the query without the insert, the join is performed with Hash Match. So the select statement is the same, but in the context of an insert it uses the slower nested loop. I have added non-clustered index on the D.SomeParentTableID so that there is an index on both sides of the join. I.SomeParentTableID is a primary key with clustered index. Why does it use a nested loop for inserts that use a join? Is there a way to improve the performance of the join for the insert?

  • How do I ensure that a regex does not match an empty string?

    - by Dancrumb
    I'm using the Jison parser generator for Javascript and am having problems with my language specification. The program I'm writing will be a calculator that can handle feet, inches and sixteenths. In order to do this, I have the following specification: %% ([0-9]+\s*"'")?\s*([0-9]+\s*"\"")?\s*([0-9]+\s*"s")? {return 'FIS';} [0-9]+("."[0-9]+)?\b {return 'NUMBER';} \s+ {/* skip whitespace */} "*" {return '*';} "/" {return '/';} "-" {return '-';} "+" {return '+';} "(" {return '(';} ")" {return ')';} <<EOF>> {return 'EOF';} Most of these lines come from a basic calculator specification. I simply added the first line. The regex correctly matches feet, inch, sixteenths, such as 6'4" (six feet, 4 inches) or 4"5s (4 inches, 5 sixteenths) with any kind of whitespace between the numbers and indicators. The problem is that the regex also matches a null string. As a result, the lexical analysis always records a FIS at the start of the line and then the parsing fails. Here is my question: is there a way to modify this regex to guarantee that it will only match a non-zero length string?

  • How can I execute an ANTLR parser action for each item in a rule that can match more than one item?

    - by Chris Farmer
    I am trying to write an ANTLR parser rule that matches a list of things, and I want to write a parser action that can deal with each item in the list independently. Some example input for these rules is: $(A1 A2 A3) I'd like this to result in an evaluator that contains a list of three MyIdentEvaluator objects -- one for each of A1, A2, and A3. Here's a snippet of my grammar: my_list returns [IEvaluator e] : { $e = new MyListEvaluator(); } '$' LPAREN op=my_ident+ { /* want to do something here for each 'my_ident'. */ /* the following seems to see only the 'A3' my_ident */ $e.Add($op.e); } RPAREN ; my_ident returns [IEvaluator e] : IDENT { $e = new MyIdentEvaluator($IDENT.text); } ; I think my_ident is defined correctly, because I can see the three MyIdentEvaluators getting created as expected for my input string, but only the last my_ident ever gets added to the list (A3 in my example input). How can I best treat each of these elements independently, either through a grammar change or a parser action change? It also occurred to me that my vocabulary for these concepts is not what it should be, so if it looks like I'm misusing a term, I probably am. EDIT in response to Wayne's comment: I tried to use op+=my_ident+. In that case, the $op in my action becomes an IList (in C#) that contains Antlr.Runtime.Tree.CommonTree instances. It does give me one entry per matched token in $op, so I see my three matches, but I don't have the MyIdentEvaluator instances that I really want. I was hoping I could then find a rule attribute in the ANTLR docs that might help with this, but nothing seemed to help me get rid of this IList. Result... Based on chollida's answer, I ended up with this which works well: my_list returns [IEvaluator e] : { $e = new MyListEvaluator(); } '$' LPAREN (op=my_ident { $e.Add($op.e); } )+ RPAREN ; The Add method gets called for each match of my_ident.

But it shows me an error could not find an match for ostream::write(long *, unsigned int) I want to write a 4 byte long data into that file. When i tries to write data using char pointer. It runs successfully. But i want to store large value i.e. eg. 2454545454 Which can be stored in long only. I dont know how to convert 1 byte into bit. I have 1 byte of data as a character. Moreover what i m trying to do is to convert 4 chars into long and store data into it. And at the other side i want to reverse this so as to retrieve how many bytes of data i have written. long *lmem; lmem=new long; *lmem=Tsize; fo.write(lmem,sizeof(long));// error occurs here delete lmem; I am implementing steganography and i have successfully stored txt file into image but trying to retrieve that file data now.

  • User will input some filter criteria -- how can I turn it into a regular expression for String.match

    - by envinyater
    I have a program where the user will enter a string such as PropertyA = "abc_*" and I need to have the asterisk match any character. In my code, I'm grabbing the property value and replacing PropertyA with the actual value. For instance, it could be abc_123. I also pull out the equality symbol into a variable. It should be able to cover this type of criteria PropertyB = 'cba' PropertyC != '*-this' valueFromHeader is the lefthand side and value is the righthand side. if (equality.equals("=")) { result = valueFromHeader.matches(value); } else if (equality.equals("!=")) { result = !valueFromHeader.matches(value); } EDIT: The existing code had this type of replacement for regular expressions final String ESC = "\\$1"; final String NON_ALPHA = "([^A-Za-z0-9@])"; final String WILD = "*"; final String WILD_RE_TEMP = "@"; final String WILD_RE = ".*"; value = value.replace(WILD, WILD_RE_TEMP); value = value.replaceAll(NON_ALPHA,ESC); value = value.replace(WILD_RE_TEMP, WILD_RE); It doesn't like the underscore here... abcSite_123 != abcSite_123 (evaluates to true) abcSite_123$1.matches("abcSite$1123") It doesn't like the underscore...
