  • addslashes and addcslahes

    - by theband
    I was seeing today the addslashes and addcslashes in php.net, but did not get the point on what is the difference between them and what are the characters escaped in these two. <?php $originaltext = 'This text does NOT contain \\n a new-line!'; $encoded = addcslashes($originaltext, '\\'); $decoded = stripcslashes($encoded); //$decoded now contains a copy of $originaltext with perfect integrity echo $decoded; //Display the sentence with it's literal \n intact ?> If i comment the $decoded variable and echo $encoded, i get the same value which is in the original string. Can anyone clearly explain me the difference and use of these two.

    Hello I have a simple simulated aarray with two elements: bowl["fruit"]="apple"; bowl["nuts"]="brazilian"; I can access the value with an event like this: onclick="testButton00_('fruit')">with `testButton00_` function testButton00_(key){ var t = bowl[key]; alert("testButton00_: value = "+t); } However whenever I try to access the aarray from within code with a key that is just a non-explicit string I get undefined. Do I have somehow have to pass the parameter with the escaped 'key'. Any ideas? tia.

  • Do word boundaries work on symbol characters?

    - by Shawn31313
    I'm trying to implement word boundaries in my emoticons feature for a chat. But for some reason I can't seem to get the word boundaries to work. I am new to regex. So when I do: var reg = /\b\Hi\b/gi; var str = 'HiHiHi Hi HiHiHi Hi'; alert(str.replace(reg, '')); This happens: Jsfiddle It actually works fine, and does remove those 2 Hi's that are standing alone. But when I change the reg to an escaped smiley and then change the string: var reg = /\b\:\)\b/gi; var str = 'HiHi:) :) HiHiHi :)'; alert(str.replace(reg, '')); This happens: Jsfiddle It just doesn't work. The string stays the same. Is it that word boundaries can't be used on symbols? If so, how does Facebook do it on their chats?

  • bash copy with variable

    - by zaf
    I'm trying to copy files to the current directory using a bash script. In order to handle paths that need escaping a variable is used that is escaped and then supplied to the cp command. The cp command is complaining with: usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file target_file cp [-R [-H | -L | -P]] [-fi | -n] [-apvX] source_file ... target_directory I know what that means but I cannot understand why that happens. Here is the code: z="/a/b/c d e f.txt" y=`printf %q "$z"` cp $y x.txt # not working as expected echo cp $y x.txt # output is "cp /a/b/c\ d\ e\ f.txt x.txt"

  • Django date filter: how come the format used is different from the one in datetime library?

    - by sebpiq
    For formatting a date using date filter you must use the following format : {{ my_date|date:"Y-m-d" }} If you use strftime from the standard datetime, you have to use the following : my_date.strftime("%Y-%m-%d") So my question is ... isn't it ugly (I guess it is because of the % that is used also for tags, and therefore is escaped or something) ? But that's not the main question ... I would like to use the same DATE_FORMAT parametrized in settings.py all over the project, but it therefore seems that I cannot ! Is there a work around (for example a filter that removes the % after the date has been formatted like {{ my_date|date|dream_filter }}, because if I just use DATE_FORMAT = "%Y-%m-%d" I got something like %2001-%6-%12)?

  • how to escape slashes in perl command in unix script?

    - by understack
    end_date=$(date +"%m/%d/%Y") /usr/bin/perl -pi -e "s/_end_date_/${end_date}/g" filename I want to replace string '_end_date_' with current date. Since current date has slashes in it(yes I want the slashes), I need to escape them. How can I do this? I've tried several ways like replacing slashes with "\/" using sed and perl itself but it didn't work. Finally I used 'cut' to break date in 3 parts and escaped slashes but this solution doesn't look good. Any better solution?

  • Contents of a node in Nokogiri

    - by Styggentorsken
    Is there a way to select all the contents of a node in Nokogiri? <root> <element>this is <hi>the content</hi> of my æøå element</element> </root> The result of getting the content of /root/element should be this is <hi>the content</hi> of my æøå element Edit: It seems like the solution is simply to use myElement.inner_html(). The problem I had was in fact that I was relying on an old version of libxml2, which escaped all the special characters.

  • Python "string_escape" vs "unicode_escape"

    - by Mike Boers
    According to the docs, the builtin string encoding string_escape: Produce[s] a string that is suitable as string literal in Python source code ...while the unicode_escape: Produce[s] a string that is suitable as Unicode literal in Python source code So, they should have roughly the same behaviour. BUT, they appear to treat single quotes differently: >>> print """before '" \0 after""".encode('string-escape') before \'" \x00 after >>> print """before '" \0 after""".encode('unicode-escape') before '" \x00 after The string_escape escapes the single quote while the Unicode one does not. Is it safe to assume that I can simply: >>> escaped = my_string.encode('unicode-escape').replace("'", "\\'") ...and get the expected behaviour?

  • How do I escape a new line character in a .ini file so that Zend_Config_Ini reads it literally?

    - by Nick
    I am trying to store a multiple line e-mail in an ini file using PHP/Zend Framework. My string has new lines characters in it, and when I use Zend_Config_Ini to parse the ini file, the new line characters come back escaped, so they are printed out on screen, instead of a line feed. Example: // ini file message = Hi {0},\n\nThis is a test message.\nGoodbye! is parsed by Zend_Config_Ini as: Hi {0},\\n\\nThis is a test message.\\nGoodbye! which then is printed out in the email as: Hi John,\n\nThis is a test message.\nGoodbye! Instead I want the e-mail to look like this: Hi John, This is a test message. Goodbye! Does anybody know how to achieve this? Thanks!

  • Preventing SQL injecting in a database class

    - by Josh
    I'm building a database class and thought it'd be a good idea to incorporate some form of SQL injection prevention (duh!). Here's the method that runs a database query: class DB { var $db_host = 'localhost'; var $db_user = 'root'; var $db_passwd = ''; var $db_name = 'whatever'; function query($sql) { $this->result = mysql_query($sql, $this->link); if(!$this->result) { $this->error(mysql_error()); } else { return $this->result; } } } There's more in the class than that but I'm cutting it down just for this. The problem I'm facing is if I just use mysql_real_escape_string($sql, $this->link); then it escapes the entire query and leads to a SQL syntax error. How can I dynamically find the variables that need to be escaped? I want to avoid using mysql_real_escape_string() in my main code blocks, i'd rather have it in a function. Thanks.

  • Does migrating a site that is 99% several megs of static HTML from Apache to Google App Enging make

    - by JonathanHayward
    I have a large site of mostly static content, and I have entertained migrating to Google App Engine. I am wondering, not so much if it is possible as whether that is cutting a steak with a screwdriver. I see a way to do it in Django that has a bad design smell. Does migrating a literature site that is largely static HTML from Apache to Google App Engine make sense? I'm not specifically asking for a comparison to Nginx or Cherokee; I am interested in whether migrating from a traditional web hosting solution to a more cloudy type of solution recommends itself. The site is JonathansCorner.com, and is presently unavailable ("the magic blue smoke has escaped").

  • GNU/Linux interactive table content GUI editor?

    - by sdaau
    I often find myself in the need to gather data (say from the internet), into a table, for comparison reasons. I usually need the final table output in HTML or MediaWiki mostly, but often times also Latex. My biggest problem is that I often forget the correct table syntax for these markup languages, as well as what needs to be properly escaped in the inline data, for the table to render correctly. So, I often wish there was a GUI application, which provides a tabular framework - which I could stick "Always on Top" as a desktop window, and I could paste content into specific cells - before finally exporting the table as a code in the correct language. One application that partially allows this is Open/LibreOffice calc: The good thing here is that: I can drag and drop browser content into a specifically targeted table cell (here B2) "Rich" text / HTML code gets pasted For long content, the cell (column) width stays put as it originally was The bad thing is, that: when the cell height (due to content size) becomes larger than the calc window, it becomes nearly impossible to scroll calc contents up and down (at least with the mousewheel), as the view gets reset to top-right corner of the selected cell calc shows an "endless"/unlimited field of cells, so not exactly a "table" - which I find visually very confusing (and cognitively taxing) Can only export table to HTML What I would need is an application that: Allows for a limited size table, but with quick adding of rows and columns (e.g. via corresponding + buttons) Allows for quick setup of row and column height and width (as well as table size) Stays put at those sizes, regardless of size of content pasted in; if cell content overflows, cell scrollbars are shown (cell content could be possibly re-edited in a separate/new window); if table overflows over window size, window scrollbars are shown Exports table in multiple formats (I'd need both HTML and mediawiki), properly escaping cell content for each (possibility to strip HTML tags from content pasted in cells, to get plain text, is a plus) Targeting a specific cell in the table for the content paste operation is a must - it doesn't have to be drag'n'drop though, a right click over a cell with "Paste content" is enough. I'd also want the ability to click in a specific cell and type in (plain text) content immediately. So, my question is: is there an application out there that already does something like this? The reason I'm asking is that - as the screenshots show - for instance Libre/OpenOffice allows it, but only somewhat (as using it for that purpose is tedious). I know there exist some GUI editors for Linux (both for UI like guile or HTML like amaya); but I don't know them enough to pinpoint if any of them would offer this kind of functionality (and at least in my searches, that kind of functionality, if present in diverse software, seems not to be advertised). Note I'm not interested in styling an HTML table, which is why I haven't used "table designer" in the title, but "table editor" (in lack of better terms) - I'm interested in (quickly) adjusting row/column size of the table, and populating it with pasted data (which is possibly HTML) in a GUI; and finally exporting such a table as self-contained HTML (or other) code.

  • If spaces in filenames are possible, why do some of us still avoid using them?

    - by Chris W. Rea
    Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. NamingThingsLikeThis.txt -- despite most modern operating systems supporting spaces in filenames. Non-technical people must look at filenames created by geeks and wonder where we learned English. So, what are the reasons that spaces in filenames are avoided or discouraged? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant reasons, other than the practice being a vestigial preference? UPDATE: Thanks for all your answers! I'm surprised how popular this was. So, here's a summary: Six Reasons Why Geeks Prefer Filenames Without Spaces In Them It's irritating to put quotes around them when referenced on the command line (or elsewhere.) Some older operating systems didn't used to support them and us old dogs are used to that. Some tools still don't support spaces in filenames at all or very well. (But they should.) It's irritating to escape spaces when used where spaces must be escaped, such as URLs. Certain unenlightened services (e.g. file hosting, webmail) remove or replace spaces anyway! Names without spaces can be shorter, which is sometimes desirable as paths are limited.

  • File permissions question

    - by Matthew Robert Keable
    I just switched my site's server from Windows to Linux, and am finally able to control file permissions from my ftp. So, seeing that all permissions were 705 by default (and not wanting just anyone to have permission to execute), I went and changed everything to 744. Now, gif and jpg links don't work, pdf download links don't work, php links don't load, and mov files don't play. Conversely, all html files work perfectly. Setting things back doesn't seem to help. Even setting to 777 gets me nowhere. Any ideas on what might be going wrong? I've been googling file permissions all day (solved that problem with the Windows-Linux switch, which has bred a new problem), and I don't think anything I can find has escaped my attention. The site: absis-minas.com Go easy on a n00b. I took up learning php out of interest, and wound up delving into server management issues due to a very simple line of code not working the way it was supposed to. Thanks!

  • How to correctly set GNU Screen to display currently running program in hardstatus

    - by johnny_bgoode
    I posted this question on SuperUser but it's hardly getting any views, so I thought I'd ask here as well. In bash, to display the name of the current program in the GNU Screen hardstatus line takes only two configuration lines. First, tell screen what the end of your prompt normally looks like, and supply a default title for a window when you are sitting at in the shell: shelltitle "$ |bash" Next, place this escape sequence in the PS1 variable, before the characters that normally terminate the prompt '$ ' in this case: \033k\033\\\ This technique works, to a point. The hardstatus window title is updated to the name of the currently running program, and then switches back to the default title shortly after execution is finished. One major problem, however, is that this escape string is not escaped itself, causing line-wrapping problems with commands longer than the initial line. This was annoying, so I set out looking for a solution. Turns out, simply escaping the previous escape sequence corrects line wrapping: [\033k]\[\033\\\] Great! My hardstatus window title still updates to the name of the currently running program, and now my longer commands wrap to the second line correctly. However, with this new escape sequence in my PS1, screen updates the window title to the actual command I am typing, not simply the name of the current program once it is executed. I am wondering, has anyone gotten this working correctly - i.e. line wrapping and proper updating of the hardstatus window title? Thanks!

  • Same script, different behavior [migrated]

    - by Antoine_935
    I just stumbled upon an interesting bug... Still trying to figure out what is exactly happening. Maybe you can help. First, the context. I'm currently building yet another man to html converter (for some reasons I won't motivate here, but I need it). So, have a look at the screenshot below (see the link), more precisely at the outlined spots. See? On the upper shell, I have &lt ; and &gt ;, that is, escaped html. While on the shell below I have < and directly. But as you can see (or do I seriously need looking glass ?), the command man 2 semget | webmanneris the same on both sides, as is the which webmanner. The two are executed roughly at the same moment, with no modification made to the script between. [Oops, cannot post pictures just yet... Here comes the link] http://aspyct.org/media/webmanner-bug.png But the shell below is older (open about 1 hour ago). Newer shells all print out &lt ;. So my first guess was that it somehow had a cached reference to the old inode of the file, or old blocks or whatever. So I modified parts of the script, at the start and then at the end, to print different messages. And, surprise, the message shown up on both terminals. But still, same difference between &lt ; and <. I'm confused... How to explain that behavior? I'm working on a OSX 10.8 (Mountain Lion) EDIT: OK, there is one big difference: the shell below uses ruby 1.9.3, while above is 1.8.7. Is there any known difference in string handling between the two versions ?

  • What character can be safely used for naming files on unix/linux?

    - by Eric DANNIELOU
    Before yesterday, I used only lower case letters, numbers, dot (.) and underscore(_) for directories and file naming. Today I would like to start using more special characters. Which ones are safe (by safe I mean I will never have any problem)? ps : I can't believe this question hasn't been asked already on this site, but I've searched for the word "naming" and read canonical questions without success (mosts are about computer names). Edit #1 : (btw, I don't use upper case letters for file names. I don't remember why. But since a few month, I have production problems with upper case letters : Some OS do not support ascii!) Here's what happened yesterday at work : As usual, I had to create a self signed SSL certificate. As usual, I used the name of the website for the files : www2.example.com.key www2.example.com.crt www2.example.com.csr. Then comes the problem : Generate a wildcard self signed certificate. I did that and named the files example.com.key example.com.crt example.com.csr, which is misleading (it's a certificate for *.example.com). I came back home, started putting some stars in apache configuration files filenames and see if it works (on a useless home computer, not even stagging). Stars in file names really scares me : Some coworkers/vendors/... can do some script using rm find xarg that would lead to http://www.ucs.cam.ac.uk/support/unix-support/misc/horror, and already one answer talks about disaster. Edit #2 : Just figured that : does not need to be escaped. Anyone knows why it is not used in file names?

  • Oracle Text query parser

    - by Roger Ford
    Oracle Text provides a rich query syntax which enables powerful text searches.However, this syntax isn't intended for use by inexperienced end-users.  If you provide a simple search box in your application, you probably want users to be able to type "Google-like" searches into the box, and have your application convert that into something that Oracle Text understands.For example if your user types "windows nt networking" then you probably want to convert this into something like"windows ACCUM nt ACCUM networking".  But beware - "NT" is a reserved word, and needs to be escaped.  So let's escape all words:"{windows} ACCUM {nt} ACCUM {networking}".  That's fine - until you start introducing wild cards. Then you must escape only non-wildcarded searches:"win% ACCUM {nt} ACCUM {networking}".  There are quite a few other "gotchas" that you might encounter along the way.Then there's the issue of scoring.  Given a query for "oracle text query syntax", it would be nice if we could score a full phrase match higher than a hit where all four words are present but not in a phrase.  And then perhaps lower than that would be a document where three of the four terms are present.  Progressive relaxation helps you with this, but you need to code the "progression" yourself in most cases.To help with this, I've developed a query parser which will take queries in Google-like syntax, and convert them into Oracle Text queries. It's designed to be as flexible as possible, and will generate either simple queries or progressive relaxation queries. The input string will typically just be a string of words, such as "oracle text query syntax" but the grammar does allow for more complex expressions:  word : score will be improved if word exists  +word : word must exist  -word : word CANNOT exist  "phrase words" : words treated as phrase (may be preceded by + or -)  field:(expression) : find expression (which allows +,- and phrase as above) within "field". So for example if I searched for   +"oracle text" query +syntax -ctxcatThen the results would have to contain the phrase "oracle text" and the word syntax. Any documents mentioning ctxcat would be excluded from the results. All the instructions are in the top of the file (see "Downloads" at the bottom of this blog entry).  Please download the file, read the instructions, then try it out by running "parser.pls" in either SQL*Plus or SQL Developer.I am also uploading a test file "test.sql". You can run this and/or modify it to run your own tests or run against your own text index. test.sql is designed to be run from SQL*Plus and may not produce useful output in SQL Developer (or it may, I haven't tried it).I'm putting the code up here for testing and comments. I don't consider it "production ready" at this point, but would welcome feedback.  I'm particularly interested in comments such as "The instructions are unclear - I couldn't figure out how to do XXX" "It didn't work in my environment" (please provide as many details as possible) "We can't use it in our application" (why not?) "It needs to support XXX feature" "It produced an invalid query output when I fed in XXXX" Downloads: parser.pls test.sql

  • Use RegEx in Java to extract parameters in between parentheses

    - by lars_bx
    I'm writing a utility to extract the names of header files from JSPs. I have no problem reading the JSPs line by line and finding the lines I need. I am having a problem extracting the specific text needed using regex. After looking at many similar questions I'm hitting a brick wall. An example of the String I'll be matching from within is: <jsp:include page="<%=Pages.getString(\"MY_HEADER\")%>" flush="true"></jsp:include> All I need is MY_HEADER for this example. Any time I have this tag: <%=Pages.getString I need what comes between this: <%=Pages.getString(\" and this: )%> Here is what I have currently (which is not working, I might add) : String currentLine; while ((currentLine = fileReader.readLine()) != null) { Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\]*)"); Matcher matcher = pattern.matcher(currentLine); while(matcher.find()) { System.out.println(matcher.group(1).toString()); }} I need to be able to use the Java RegEx API and regex to extract those header names. Any help on this issue is greatly appreciated. Thanks! EDIT: Resolved this issue, thankfully. The tricky part was, after being given the right regex, it had to be taken into account that the String I was feeding to the regex was always going to have two " / " characters ( (/"MY_HEADER"/) ) that needed to be escaped in the pattern. Here is what worked (thanks to the help ;-)): Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\\"]*)");

  • SQLiteQueryBuilder.buildQuery not using selectArgs?

    - by user297468
    Alright, I'm trying to query a sqlite database. I was trying to be good and use the query method of SQLiteDatabase and pass in the values in the selectArgs parameter to ensure everything got properly escaped, but it wouldn't work. I never got any rows returned (no errors, either). I started getting curious about the SQL that this generated so I did some more poking around and found SQLiteQueryBuilder (and apparently Stack Overflow doesn't handle links with parentheses in them well, so I can't link to the anchor for the buildQuery method), which I assume uses the same logic to generate the SQL statement. I did this: SQLiteQueryBuilder builder = new SQLiteQueryBuilder(); builder.setTables(BarcodeDb.Barcodes.TABLE_NAME); String sql = builder.buildQuery(new String[] { BarcodeDb.Barcodes.ID, BarcodeDb.Barcodes.TIMESTAMP, BarcodeDb.Barcodes.TYPE, BarcodeDb.Barcodes.VALUE }, "? = '?' AND ? = '?'", new String[] { BarcodeDb.Barcodes.VALUE, barcode.getValue(), BarcodeDb.Barcodes.TYPE, barcode.getType()}, null, null, null, null); Log.d(tag, "Query is: " + sql); The SQL that gets logged at this point is: SELECT _id, timestamp, type, value FROM barcodes WHERE (? = '?' AND ? = '?') However, here's what the documentation for SQLiteQueryBuilder.buildQuery says about the selectAgs parameter: You may include ?s in selection, which will be replaced by the values from selectionArgs, in order that they appear in the selection. ...but it isn't working. Any ideas?
