  • Why are months off by one with Java SimpleDateFormat ?

    - by Natim
    Hello, I am using SimpleDateFormat to display a Calendar like this : public String getDate() { String DATE_FORMAT = "EEEE, dd/MM/yyyy HH:mm:ss"; SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT); System.err.println(date.getTime().getMonth()); return sdf.format(date.getTime()); } The shell returns 6 and the display : mardi, 06/07/2010 12:44:52 It can't be possible ? Why ? Thanks

  • IRC-Bot in Ruby: PRIVMSG sends only last word of string

    - by Marius Schuller
    I'm on learning ruby and I took a already done IRC-Bot from the web which just connects to a given serven and not much more. Then I added some features (in my case I try to implement a voting where to eat lunch). Now these work fine so far but I don't know if the ruby script does something wrong or there is something wrong with the IRC-server. On the one I tested the Bot it worked well, giving an output like this: 09:14 < Wayne> !EssNA 09:14 < EssNABot> [-=EssNA-Vote=-] 09:14 < EssNABot> Options are: 09:14 < EssNABot> McDonalds. 0 09:14 < EssNABot> Currywurst 0 09:14 < EssNABot> Hendl..... 0 09:14 < EssNABot> Salatbar.. 0 09:14 < EssNABot> Griechr... 0 09:14 < EssNABot> Metzger... 0 09:14 < EssNABot> Merowinger 0 09:14 < EssNABot> Lidl...... 0 09:14 < EssNABot> Voting time is 600 seconds. The bot itself sees that like this: --> PRIVMSG #test [-=EssNA-Vote=-] --> PRIVMSG #test Options are: --> PRIVMSG #test McDonalds. 0 --> PRIVMSG #test Currywurst 0 --> PRIVMSG #test Hendl..... 0 --> PRIVMSG #test Salatbar.. 0 --> PRIVMSG #test Griechr... 0 --> PRIVMSG #test Metzger... 0 --> PRIVMSG #test Merowinger 0 --> PRIVMSG #test Lidl...... 0 --> PRIVMSG #test Voting time is 600 seconds. But on the irc which it should run on if its done the output users will see looks like this: 09:14 < Wayne> !EssNA 09:14 < EssNABot> [-=EssNA-Vote=-] 09:14 < EssNABot> are: 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> 0 09:14 < EssNABot> seconds. The output the bot gives is the same as on the server on which the output for users works. Seems to me that the problem is the IRC-server, maybe someone can point me in the right direction? Yours, Marius

  • preg_match find multiple partial appearances of a word in a string

    - by Rubytastic
    Any regex gurus around here? its driving me crazy. Say I have this string: "bookstore books Booking" I want to count the number "books" appears in this and return the number. Currently I have this which is not working: $string = "bookstore books Booking"; if (preg_match_all('/\b[A-Z]+books\b/', $string, $matches)) { echo count($matches[0]) . " matches found"; } else { echo "match NOT found"; } On top of this the "books" inside the preg_match_all should become a $var Anyone an idea how to count correctly?

  • Replicating Java's DecimalFormat in C#

    - by Frank Krueger
    I am trying to replicate a subset of Java's DecimalFormat class. Below is what I've come up with. Does this look right to everyone? public class DecimalFormat : NumberFormat { int _maximumFractionDigits; int _minimumFractionDigits; string _format; void RebuildFormat () { _format = "{0:0."; _format += new string ('0', _minimumFractionDigits); if (_maximumFractionDigits > _minimumFractionDigits) { _format += new string ('#', _maximumFractionDigits - _minimumFractionDigits); } _format += "}"; } public override string format (object value) { return string.Format (_format, value); } public override void setMaximumFractionDigits (int n) { _maximumFractionDigits = n; RebuildFormat (); } public override void setMinimumFractionDigits (int n) { _minimumFractionDigits = n; RebuildFormat (); } public override void setGroupingUsed (bool g) { } public static NumberFormat getInstance () { return new DecimalFormat (); } }

  • Python: Convert format string to regular expression

    - by miracle2k
    The users of my app can configure the layout of certain files via a format string. For example, the config value the user specifies might be: layout = '%(group)s/foo-%(locale)s/file.txt' I now need to find all such files that already exist. This seems easy enough using the glob module: glob_pattern = layout % {'group': '*', 'locale': '*'} glob.glob(glob_pattern) However, now comes the hard part: Given the list of glob results, I need to get all those filename-parts that matched a given placeholder, for example all the different "locale" values. I thought I would generate a regular expression for the format string that I could then match against the list of glob results (or then possibly skipping glob and doing all the matching myself). But I can't find a nice way to create the regex with both the proper group captures, and escaping the rest of the input. For example, this might give me a regex that matches the locales: regex = layout % {'group': '.*', 'locale': (.*)} But to be sure the regex is valid, I need to pass it through re.escape(), which then also escapes the regex syntax I have just inserted. Calling re.escape() first ruins the format string. I know there's fnmatch.translate(), which would even give me a regex - but not one that returns the proper groups. Is there a good way to do this, without a hack like replacing the placeholders with a regex-safe unique value etc.? Is there possibly some way (a third party library perhaps?) that allows dissecting a format string in a more flexible way, for example splitting the string at the placeholder locations?

  • Finding character in String in Vector.

    - by SoulBeaver
    Judging from the title, I kinda did my program in a fairly complicated way. BUT! I might as well ask anyway xD This is a simple program I did in response to question 3-3 of Accelerated C++, which is an awesome book in my opinion. I created a vector: vector<string> countEm; That accepts all valid strings. Therefore, I have a vector that contains elements of strings. Next, I created a function int toLowerWords( vector<string> &vec ) { for( int loop = 0; loop < vec.size(); loop++ ) transform( vec[loop].begin(), vec[loop].end(), vec[loop].begin(), ::tolower ); that splits the input into all lowercase characters for easier counting. So far, so good. I created a third and final function to actually count the words, and that's where I'm stuck. int counter( vector<string> &vec ) { for( int loop = 0; loop < vec.size(); loop++ ) for( int secLoop = 0; secLoop < vec[loop].size(); secLoop++ ) { if( vec[loop][secLoop] == ' ' ) That just looks ridiculous. Using a two-dimensional array to call on the characters of the vector until I find a space. Ridiculous. I don't believe that this is an elegant or even viable solution. If it was a viable solution, I would then backtrack from the space and copy all characters I've found in a separate vector and count those. My question then is. How can I dissect a vector of strings into separate words so that I can actually count them? I thought about using strchr, but it didn't give me any epiphanies.

  • Java Code Formating

    - by the qwerty
    I'm using FreeMarker to generate java code, but as most of it is dynamically generated it's difficult to control the code formation. I want to get code well formatted. Does anyone knows a lib or something like a pretty printer for java code?

  • Padding a string in Postgresql with rpad without truncating it

    - by dmoebius
    Using Postgresql 8.4, how can I right-pad a string with blanks without truncating it when it's too long? The problem is that rpad truncates the string when it is actually longer than number of characters to pad. Example: SELECT rpad('foo', 5); ==> 'foo ' -- fine SELECT rpad('foo', 2); ==> 'fo' -- not good, I want 'foo' instead. The shortest solution I found doesn't involve rpad at all: SELECT 'foo' || repeat(' ', 5-length('foo')); ==> 'foo ' -- fine SELECT 'foo' || repeat(' ', 2-length('foo')); ==> 'foo' -- fine, too but this looks ugly IMHO. Note that I don't actually select the string 'foo' of course, instead I select from a column: SELECT colname || repeat(' ', 30-length(colname)) FROM mytable WHERE ... Is there a more elegant solution?

  • What's the best way to format long strings of HTML in PHP?

    - by dclowd9901
    I know it's really a subjective question, but for best-practices (and readability), I can't seem to get a fix on the best way to format long strings of HTML. I typically do it like this: echo ' <div> <p>Content Inside</p> <div class="subbox"> <ul> <li>etc.</li> <li>etc.</li> <li>etc.</li> <li>etc.</li> </ul> </div> </div> '; But I still don't like the outcome, especially if this appears in the middle of a large block of code. It just feels messy.

  • tool to auto-format R code

    - by Keith
    Is there any tool (editor, script, whatever...) available that can automatically reformat R code? It does not need to be customizable but it must be able to recognize statements separated by either semicolons or newlines since this code has both. If it can put all statements on a separate line, consistently indent code blocks and consistently place braces I will be very happy.

  • Why not put all braces inline in C++/C#/Java/javascript etc.?

    - by DanM
    Of all the conventions out there for positioning braces in C++, C#, Java, etc., I don't think I've ever seen anyone try to propose something like this: public void SomeMethod(int someInput, string someOtherInput) { if (someInput > 5) { var addedNumber = someInput + 5; var subtractedNumber = someInput - 5; } else { var addedNumber = someInput + 10; var subtractedNumber = someInput; } } public void SomeOtherMethod(int someInput, string someOtherInput( { ... } But why not? I'm sure it would take some getting used to, but I personally don't have any difficulty following what's going on here. I believe indentation is the dominant factor in being able to see how code is organized into blocks and sub-blocks. Braces are just visual noise to me. They are these ugly things that take up lines where I don't want them. Maybe I just feel that way because I was weened on basic (and later VB), but I just don't like braces taking up lines. If I want a gap between blocks, I can always add an empty line, but I don't like being forced to have gaps simply because the convention says the closing brace needs to be on its own line. I made this a community wiki because I realize this is not a question with a defined answer. I'm just curious what people think. I know that no one does this currently (at least, not that I've seen), and I know that the auto-formatter in my IDE doesn't support it, but are there are any other solid reasons not to format code this way, assuming you are working with a modern IDE that color codes and auto-indents? Are there scenarios where it will become a readability nightmare? Better yet, are you aware of any research on this?

  • C++ word to bytes

    - by Vit
    Hi, I tried to read CPUID using assembler in C++. I know there is function for it in , but I want the asm way. So, after CPUID is executed, it should fill eax,ebx,ecx registers with ASCII coded string. But my problem is, since I can in asm adress only full, or half eax register, how to break that 32 bits into 4 bytes. I used this: #include <iostream> #include <stdlib.h> int main() { _asm { cpuid /*There I need to mov values from eax,ebx and ecx to some propriate variables*/ } system("PAUSE"); return(0); }

  • Weird behaviour of Calendar and DateFormat

    - by Nejc
    I encountered really strange behaviour when constructing a Calendar object and then formating it in a particular style. Let the code do the talking: public class Test { public static void main(String[] args) { SimpleDateFormat frmt = new SimpleDateFormat(); frmt.applyPattern("yyyy-MM-dd"); GregorianCalendar date = new GregorianCalendar(2012,1,1); System.out.println(frmt.format(date.getTime())); } } The output is: 2012-02-01 The expected output is of course: 2012-01-01 What am I doing wrong?

    given an xml string like this : <some><nested><xml>value</xml></nested></some> what's the best option(using ruby) to format it readable like : <some> <nested> <xml>value</xml> </nested> </some> I've found an answer here: what's the best way to format an xml string in ruby?, which is really helpful. But it formats xml like: <some> <nested> <xml> value </xml> </nested> </some> As my xml string is a little big in length. So it is not readable in this format. Thanks in advance!

  • Fluent NHibernate Column Mapping with Reserved Word

    - by Josh Close
    I've read that using a back tick ` should allow for using of reserved words. I'm using SQL Server and Fluent NHibernate and have a column name "File". If I map it with "`File" it tries using [Fil] so it's adding the brackets correctly, but dropping the "e" from the end. If I map it as "`Filee" it uses [File] correctly. Am I doing something wrong or is this a bug in NHibernate or Fluent Nhibernate?

  • convert variable with mixed date formats to one format in r

    - by jalapic
    A sample of my dataframe: date 1 25 February 1987 2 20 August 1974 3 9 October 1984 4 18 August 1992 5 19 September 1995 6 16-Oct-63 7 30-Sep-65 8 22 Jan 2008 9 13-11-1961 10 18 August 1987 11 15-Sep-70 12 5 October 1994 13 5 December 1984 14 03/23/87 15 30 August 1988 16 26-10-1993 17 22 August 1989 18 13-Sep-97 I have a large dataframe with a date variable that has multiple formats for dates. Most of the formats in the variable are shown above- there are a couple of very rare others too. The reason why there are multiple formats is that the data were pulled together from various websites that each used different formats. I have tried using straightforward conversions e.g. strftime(mydf$date,"%d/%m/%Y") but these sorts of conversion will not work if there are multiple formats. I don't want to resort to multiple gsub type editing. I was wondering if I am missing a more simple solution? Code for example: structure(list(date = structure(c(12L, 8L, 18L, 6L, 7L, 4L, 14L, 10L, 1L, 5L, 3L, 17L, 16L, 11L, 15L, 13L, 9L, 2L), .Label = c("13-11-1961", "13-Sep-97", "15-Sep-70", "16-Oct-63", "18 August 1987", "18 August 1992", "19 September 1995", "20 August 1974", "22 August 1989", "22 Jan 2008", "03/23/87", "25 February 1987", "26-10-1993", "30-Sep-65", "30 August 1988", "5 December 1984", "5 October 1994", "9 October 1984"), class = "factor")), .Names = "date", row.names = c(NA, -18L), class = "data.frame")
