I tried this but only got a syntax error:
<?php
$a = true;
$str = <<< EOF
{$a ? 1 : 2}
EOF;
echo $str;
Is it possible to use such kind of conditional statement inside heredoc?
From wiki: In computing, just-in-time compilation (JIT), also known as dynamic translation, is a technique for improving the runtime performance of a computer program.
So I guess JVM has another compiler, not javac, that only compiles bytecode to machine code at runtime, while javac compiles sources to bytecode,is that right?
The compiler complains about this code:
HashMap<String,int> userName2ind = new HashMap<String,int>();
for (int i=0; i<=players.length; i++) {
userName2ind.put(orderedUserNames[i],i+1);
}
It writes "unexpected type" and point on int. If I replace int by String and i+1 by i+"1", the compilation goes OK. What is wrong with in here?
I want to perform a printf() to display when the currently executing code was last compiled. Does C/C++ provide a macro that gives you that resolves to a timestamp during compilation?
i want to speed my code compilation..I have searched the internet and heard that psyco is a very tool to improve the speed.i have searched but could get a site for download.
i have installed any additional libraries or modules till date in my python..
can psyco user,tell where we can download the psyco and its installation and using procedures??
i use windows vista and python 2.6 does this work on this ??
What was the most stupid code mistake you have ever made that had great consequences, e.g. you were fired?
For example, a friend of mine wrote a cycle with conditional statement for break that was never true, which caused one high-loaded site to hang up for the whole night.
I was hoping someone could explain why my application when loaded uses varying amounts of RAM. I'm speaking about a compiled version that uses the exe directly. It's a pretty basic applications and there are no conditional branches in the startup of the application. Yet every time I start it up the RAM amount varies from 6MB-16MB.
I know it's on the small end of usage anyways but I'm curious of why this happens.
I'm writing a small ruby daemon that I am hoping will do the following:
Check if a specific directory has files (in this case, .yml files)
If so, take the first file (numerically sorted preferrably), and parse into a hash
Do a 'yield', with this hash as the argument
What I have right now is like:
loop do
get_next_in_queue { |s| THINGS }
end
def get_next_in_queue
queue_dir = Dir[File.dirname(__FILE__)+'/../queue']
info = YAML::load_file(queue_dir[0]) #not sure if this works or not
yield info
end
I'd like to make the yield conditional if possible, so it only happens if a file is actually found. Thanks!
Based upon SO answer "my ($export = $doc) =~ s{.odt}{.pdf};" why does this Perl script produce a compile error?
$ cat so.pl
#!/usr/bin/perl
my $doc ="x.odt";
my ($export = $doc) =~ s{\.odt}{.pdf};
$ ./so.pl
Can't declare scalar assignment in "my" at ./so.pl line 3, near ") =~"
Execution of ./so.pl aborted due to compilation errors.
I had to use threading to avoid "XSL Compilation time-out error"
Now the problem I am facing is:
It gives error, saying the output-string(generated as a result of transformation) is null!!
Here is my C# code : [click_me]
And the errors I am getting is copied in this text file : [click_me]
And the original code without threading .. [click_me]
I'm using Visual Studio 2008 on Windows 7. When I'm editing .aspx file VS stalls and thinks for about 3 sec every time I add a tag. Very frustrating. I'm guessing its doing some kind of compilation or checking. What can I do to make VS more responsive?
Has anyone expirience this error before: this happens when I hit CTRL + space , here is the error :
For those who has tinyurl blocked: This compilation unit is not on the build path of the java project.
This is a maven project, mvn eclipse:eclipse doesn't help I mean it compiles and runs just fine just something is wrong and I can't figure out what. I checkouted this project from SVN, it wasn't developed on my PC.
To define constants, what is the more common and correct way? What is the cost, in terms of compilation, linking, etc., of defining constants with #define? It is another way less expensive?
In C#, is it possible to have same parameters yet override each other(they are different in the return types)
public override Stocks[] Search(string Field,string Param){ //some code}
public override Stocks Search(string Field, string Param){//some code}
C# returns compilation error
i'm trying to run a conditional statement in a class i'm placing in my App_Code folder
the condition is whether the person is logged in or not. I normally have two ways to do this in my masterpage and ASPX's
if (!User.IsAuthenticated) or if(Profile.username = "anonymous")
however neither of these things seem available to me in the .cs i'm making. anyone know what i'm missing? maybe a using namespace up top?
Hai,
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
This error is occur while creating a new template in google sites using java programming.
Hi to all,
I installed IDE NetBeans for C/C++ development. I created C project with main.c and makefile generated netbeans. When i add test.h file in my project and try to compile it, i see that netbeans does not see this header file, and that I would not write it, even if there are errors anyway compilation is successful. How to connect a header file in netbeans?
Thanks.
I have a custom class and check that a property isn't 0x0 by doing:
if(myinstance.someproperty != nil){
//do something
}
However, even if someproperty is 0x0, I still go into the conditional. someproperty is of another class type. Is there some other way to check this?
I have following code:
static __inline__ LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
After compilation I got following warning:
inlining is unlikely but function size may grow
I removed the inline and changed into the following :
static LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
Now I get the following warning:
list_List is defined but not used.
Can anybody please suggest me how can remove that warning.
As I found out that I can use only numerical values in C++'s switch statements, I thought that there then must be some deeper difference between it and a bunch of if-else's.
Therefore I asked myself:
(How) does switch differ from if-elseif-elseif in terms of runtime speed, compile time optimization and general compilation? I'm mainly speaking of MSVC here.
Why can't i define a variable recursively in a code block?
scala> {
| val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
| }
<console>:9: error: forward reference extends over definition of value fibs
val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
^
scala> val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _}
fibs: Stream[Int] = Stream(1, ?)
lazy keyword solves this problem, but i can't understand why it works without a code block but throws a compilation error in a code block.
hello,
In ASP.NET when we add image in design page we are getting image but after compilation we are not getting image. how to get image,what we have to do..
I'm working an a very large scale projects, where the compilation time is very long. What tools can I use (preferably open source) on Linux, to find the most heavily included files and that optimize their useages?
Just to be clearer, I need a tool which will, given the dependencies, show me which headers are the most included. By the way, we do use distributed compiling
