  • Python code to use a regular expression to make sure a string is alphanumeric plus . - _

    - by Warlax
    Hi, I looked and searched and couldn't find what I needed although I think it should be simple (if you have any Python experience, which I don't). Given a string, I want to verify, in Python, that it contains ONLY alphanumeric characters: a-zA-Z0-9 and . _ - examples: Accepted: bill-gates Steve_Jobs Micro.soft Rejected: Bill gates -- no spaces allowed [email protected] -- @ is not alphanumeric I'm trying to use: if re.match("^[a-zA-Z0-9_.-]+$", username) == True: But that doesn't seem to do the job...

  • Replace text in folder names

    - by dannyb
    How can I replace the same text in folder names in linux? Say I have "Photos_Jun", "Photos_July", "Photos_Aug", etc. whats the simplest way I can rename them like "Photos Jun", "Photos July", etc (basically I want to replace the underscore with a space " ". I have about 200 of these folders. I was looking at solution: http://stackoverflow.com/questions/1836563/how-can-i-easily-bulk-rename-files-with-perl It looks like what im looking for however, I dont know how to make a regular expression to match folders that are alphanumeric followed by a "_". All files have non-numeric names, so I think [a-zA-Z] is the right way to start. perl -e 'foreach $f (glob("File\\ Name*")) { $nf = $f; $nf =~ s/(\d+)$/sprintf("%03d",$1)/e; print `mv \"$f\" \"$nf\"`;}' Thanks for any help!

  • How can I use a regular expression to match something in the form 'stuff=foo' 'stuff' = 'stuff' 'mor

    - by PherricOxide
    I need a regexp to match something like this, 'text' | 'text' | ... | 'text'(~text) = 'text' | 'text' | ... | 'text' I just want to divide it up into two sections, the part on the left of the equals sign and the part on the right. Any of the 'text' entries can have "=" between the ' characters though. I was thinking of trying to match an even number of 's followed by a =, but I'm not sure how to match an even number of something.. Also note I don't know how many entries on either side there could be. A couple examples, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) = '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' Should extract, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) and, '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) = '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Should extract, '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) and, '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Also note the little tilda bit at the end of the first section is optional, so I can't just look for that.

  • Converting John Resig's JavaScript Templating Engine to work with PHP Templates

    - by Serhiy
    I'm trying to convert the John Resig's Templating Engine to work with PHP. Essentially what I would like to achieve is the ability to use certain Kohana Views via a JavaScript templating engine, that way I can use the same views for both a standard PHP request and a jQuery AJAX request. I'm starting with the basics and would like to be able to convert http://github.com/nje/jquery-tmpl/blob/master/jquery.tmpl.js To work with php like so... ### From This ### <li><a href="{%= link %}">{%= title %}</a> - {%= description %}</li> ### Into This ### <li><a href="<?= $link ?>"><?= $title ?></a> - <?= description ?></li> The RexEx in it is a bit over my head and it's apparently not as easy as changing the %} to ? in lines 148 to 158. Any help would be highly appreciated. I'm also not sure of how to take care of the $ difference that PHP variables have. Thanks, Serhiy

  • PHP/SQL/Wordpress: Group a user list by alphabet

    - by rayne
    I want to create a (fairly big) Wordpress user index with the users categorized alphabetically, like this: A Amy Adam B Bernard Bianca and so on. I've created a custom Wordpress query which works fine for this, except for one problem: It also displays "empty" letters, letters where there aren't any users whose name begins with that letter. I'd be glad if you could help me fix this code so that it only displays the letter if there's actually a user with a name of that letter :) I've tried my luck by checking how many results there are for that letter, but somehow that's not working. (FYI, I use the user photo plugin and only want to show users in the list who have an approved picture, hence the stuff in the SQL query). <?php $alphabet = range('A', 'Z'); foreach ($alphabet as $letter) { $user_count = $wpdb->get_results("SELECT COUNT(*) FROM wp_users WHERE display_name LIKE '".$letter."%' ORDER BY display_name ASC"); if ($user_count > 0) { $user_row = $wpdb->get_results("SELECT wp_users.user_login, wp_users.display_name FROM wp_users, wp_usermeta WHERE wp_users.display_name LIKE '".$letter."%' AND wp_usermeta.meta_key = 'userphoto_approvalstatus' AND wp_usermeta.meta_value = '2' AND wp_usermeta.user_id = wp_users.ID ORDER BY wp_users.display_name ASC"); echo '<li class="letter">'.$letter.''; echo '<ul>'; foreach ($user_row as $user) { echo '<li><a href="/author/'.$user->user_login.'">'.$user->display_name.'</a></li>'; } echo '</ul></li>'; } } ?> Thanks in advance!

  • preg_replace to capitalize a letter after a quote

    - by Summer
    I have names like this: $str = 'JAMES "JIMMY" SMITH' I run strtolower, then ucwords, which returns this: $proper_str = 'James "jimmy" Smith' I'd like to capitalize the second letter of words in which the first letter is a double quote. Here's the regexp. It appears strtoupper is not working - the regexp simply returns the unchanged original expression. $proper_str = preg_replace('/"([a-z])/',strtoupper('$1'),$proper_str); Any clues? Thanks!!

    Hello! I have some hidden inputs like this <input name="exam.normals[1].blahblah" ..../> I would like somehow to replace the [1] with a number that I want (index).

With regexp I don’t know how to do the replace. good...

  • MSSQL Efficiently dropping a group of rows with millions and millions of rows

    - by Net Citizen
    I recently asked this question: http://stackoverflow.com/questions/2519183/ms-sql-share-identity-seed-amongst-tables (Many people wondered why) I have the following layout of a table: Table: Stars starId bigint categoryId bigint starname varchar(200) But my problem is that I have millions and millions of rows. So when I want to delete stars from the table Stars it is too intense on MS SQL. I cannot use built in partitioning for 2005+ because I do not have an enterprise license. When I do delete though, I always delete a whole category Id at a time. I thought of doing a design like this: Table: Star_1 starId bigint CategoryId bigint constaint rock=1 starname varchar(200) Table: Star_2 starId bigint CategoryId bigint constaint rock=2 starname varchar(200) In this way I can delete a whole category and hence millions of rows in O(1) by doing a simple drop table. My question is, is it a problem to have thousands of tables in your MS SQL? The drop in O(1) is extremely desirable to me. Maybe there's a completely different solution I'm not thinking of?

  • case-insensitive regexp match on non-english text in perl cgi script

    - by jonny
    ok. I have list of catalog paths and need to filter out some of them. Match pattern comes in non-Unicode encoding. Tried following: require 5.004; use POSIX qw(locale_h); my $old_locale = setlocale(LC_ALL); setlocale(LC_ALL, "ru_RU.cp1251"); @{$data -> {doc_folder_rights}} = grep { $_->{doc_folder} =~/$_REQUEST{q}/i; # catalog path pattern in $_REQUEST{q} } @{$data -> {doc_folder_rights}}; setlocale(LC_ALL, $old_locale); What I need is case-insensitive regexp pattern matching when pattern contains russsian letters.

  • Regular Expression for any number divisible by 60 using C# .Net ?

    - by Steve Johnson
    Hi there, I need to apply validation on input time intervals that are taken in as seconds. Now i am not really good at Regular expressions. So can any body help making a regular expression that can test whether a number is divisible by 60. I was wondering if i could use to test one that check that the number is divisible by 10 and then check whether the same is divisible by 6. For number divisible by 10 here [\d*0] is the expression i guess. Please correct me if i am wrong. Hope somebody solves my problem. Thanks

  • Splitting a string according to a delimiter when elements in the string can contain the delimiter

    - by Vivin Paliath
    I have a string that looks like this: "#Text() #SomeMoreText() #TextThatContainsDelimiter(#blah) #SomethingElse()" I'd like to get back [#Text(), #SomeMoreText(), #TextThatContainsDelimiter(#blah), #SomethingElse()] One way I thought about doing this was to require that the # to be escaped into \#, which makes the input string: "#Text() #SomeMoreText() #TextThatContainsDelimiter(\#blah) #SomethingElse()" I can then split it using /[^\\]#/ which gives me: [#Text(), SomeMoreText, TextThatContainsDelimiter(\#blah), SomethingElse()] The first element will contain # but I can strip it out. However, is there a cleaner way to do this without having to escape the #, and which ensures that the first element will not contain a #? Basically I'd like it to split by # only if the # is not enclosed by parentheses. My hunch is that since the # is context-sensitive and and regular expressions are only suited for context-free strings, this may not be the right tool. If so, would I have to write a grammar for this and roll my own parser/lexer?

  • PHP Key name array

    - by Sean McRaghty
    I have an array $data fruit => apple, seat => sofa, etc. I want to loop through so that each key becomes type_key[0]['value'] so eg type_fruit[0]['value'] => apple, type_seat[0]['value'] => sofa, and what I thought would do this, namely foreach ($data as $key => $value) { # Create a new, renamed, key. $array[str_replace("/(.+)/", "type_$1[0]['value']", $key)] = $value; # Destroy the old key/value pair unset($array[$key]); } print_r($array); Doesn't work. How can I make it work? Also, I want everything to be in the keys (not the values) to be lowercase: is there an easy way of doing this too? Thanks.

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Need an algorithm to group several parameters of a person under the persons name

    - by QuickMist
    Hi. I have a bunch of names in alphabetical order with multiple instances of the same name all in alphabetical order so that the names are all grouped together. Beside each name, after a coma, I have a role that has been assigned to them, one name-role pair per line, something like whats shown below name1,role1 name1,role2 name1,role3 name1,role8 name2,role8 name2,role2 name2,role4 name3,role1 name4,role5 name4,role1 ... .. . I am looking for an algorithm to take the above .csv file as input create an output .csv file in the following format name1,role1,role2,role3,role8 name2,role8,role2,role4 name3,role1 name4,role5,role1 ... .. . So basically I want each name to appear only once and then the roles to be printed in csv format next to the names for all names and roles in the input file. The algorithm should be language independent. I would appreciate it if it does NOT use OOP principles :-) I am a newbie.

  • Wanted: a very simple java RegExp API

    I'm tired of writing Pattern p = Pattern.compile(... Matcher m = p.matcher(str); if (m.find()) { ... Over and over again in my code. I was going to write a helper class to make it neater, but I then I wondered: is there a library that tries to provide a simpler facade for Regular Expressions in Java? I'm thinking something in the style of commons-lang and Guava.
