I know that you can make a function file in Octave in which the file name is the same as the function which defines one function, but I would like to define multiple functions in one file. Is there any way to do this, or do I need a separate file for each function.
In this answer I will assume that your main objective is a tidy workspace rather than explicitly a one-file requirement.
Let's get the one-file approach out of the way. You can create a script m-file (not a function m-file), and define a number of command-line functions there. The octave manual has a section on this. Here's an example:
% in file loadfunctionDefinitions.m
1; % statement with side-effect, to mark this file as a script. See docs.
function Out = Return1(); Out = 1; end
function Out = Return2(); Out = 2; end
% ... etc
% in your main octave session / main script:
X = Return1() + Return2();
However, this is generally not recommended. Especially if you would require matlab compatible code, since matlab introduced 'script-local functions' much later than octave, and decided to do it in a manner incompatible to the existing octave implementation: matlab expects script-local functions to be defined at the end of the script; octave expects them to be defined before first use. However, if you use normal function files, everything is fine.
While I appreciate the "I don't like a folder full of functions" sentiment, the one-function-per-file approach actually has a lot of benefits (especially if you program from the terminal, which makes a wealth of tools twice as useful). E.g. you can easily use grep to find which functions make use of a particular variable. Or compare changes in individual functions from different commits, etc.
Typically the problem is more one of having such function files littering the directory, when other important files are present, e.g. data etc, and having so many files in one place makes finding what you want hard to spot, and feels untidy. But rather than have a single file with command-line definitions, there are a number of other approaches you can take, which are probably also better from a programmatic point of view, e.g.:
Simply create a 'helper functions' folder, and add it to your path.
Use subfunctions in your main functions whenever this is appropriate, to minimize the number of unnecessary files
Use a private functions folder
Use a 'package directory', i.e. a folder starting with the character '+', which creates a namespace for the functions contained inside. E.g. ~/+MyFunctions/myfun.m would be accessed from ~/ via MyFunctions.myfun(), without having to add +MyFunctions to the path (in fact you're not supposed to).
Create a proper class directory, and make your functions methods of that class
The last option may also achieve a one-file solution, if you use a newer-style classdef based class, which allows you to define methods in the same file as the class definition. Note however that octave-support for classdef-defined classes is still somewhat limited.
I'm using Kohana framework which allows for multiple class definitions (in application and system subfolders). I'm using phpstorm as an IDE which gives me messages multiple definitions exist for class . Is there any way to tell phpStorm which class definition is correct?

You cannot, unfortunately.

ATM you either just ignore the under-waving .. or you can configure that inspection to not to report such cases (Settings/Preferences | Editor | Inspections | PHP | Undefined | Undefined class, it has Don't report multiple class declaration potential problems checkbox).
Even with that inspection configured, IDE will still ask you what class declaration to jump to (and this is correct behaviour as IDE does not know if you want to see the original implementation or implement your own).
The only other way is to ensure that there is only one class with the same name in the project. For that you may use:
Mark whole folder as excluded
Mark individual file as Plain Text
Both are available via content menu in Project View and applicable to project files only (e.g. will be unavailable or will do nothing useful if tried to apply in Library scope).
You should just ignore the complete cache folder.
Go to Settings > Directories
Choose var\cache
Set it to 'Excluded'

I've found a possible solution to my problem - I can mark file as plain
As variant you can turn off inspection only for specific class. Put cursor inside underwaved class name, then Alt+Enter → Inspection options → Supress for statement
PHPStorm adds
/** #noinspection PhpUndefinedClassInspection */
above class declaration and class name is not underwaved anymore.
I've been around the web everywhere and not a single option worked for me... I've been struggling for months with it, and today I found a solution, so if none of the above works for you, try redefining the PHP Include Path List. under Settings > Languages & Frameworks > PHP, make sure only the folders containing paths to source used by your project or application is configured.
My scenario is that I do a lot of package development, and while my packages are all in one project, they are also "symlinked" in "vendor" in my composer configuration, so there is duplicated code found by PHPStorm, in the vendor folder and my packages folder. Similarly, if include paths are duplicated, or paths are configured to find code outside of your project, which is already part of the project, it will also find multiple definitions. So, excluding the symlinked folders in vendor, allows PHPStorm to only find one copy of the source to my packages, and if my packages contain vendor folders of their own, they will also show up as duplicated definitions. Remove anything in the Include Path list where it may find dipplication
Just some addition to the Andy White's comment:
Settings | Editor | Inspections | PHP | Undefined | Undefined class | Don't report multiple class declaration potential problems
I really couldn't find this config and thought it was no there now, but this is still there, but very well hidden)
It is a little counterintuitive and inconspicuous, but the needed checkbox is in the right panel, and appears only if you click on the Undefined class row:
Prolog
Guess there are several ways to solve this problem. Actually, it's just a warning and it says that phpstorm can't provide you with autocompletion so you have to work a bit harder :D
I had the same problem as many others here and solved it by ignoring unwanted.
Scenario
Had a git project with a vendor-folder after composer install. Also, there is a my-project.phar in this project that also contains some vendor stuff and this caused my warnings.
Solution
File > Preferences|Settings > Directories
There you have to possibility to exclude files and folders. In my case it's the .phar so it's a "file" and you can add it at the bottom of the settings-window.
PHPStorm will no longer see duplicates.
This is very project-specific and I guess most people have to find their own solution but pointing to this may help to find the problem easier.
Hope this helps someone :)
Somewhere in your project there are multiple definitions for the same class. I discovered I had backup copies in my project which caused this warning. I removed the backups from my Project (a good idea anyway) and it fixed the error.
I don't know how you created the other definition, but if you or anyone has this issue due to calling class_alias(), then you can solve this issue quickly.
Consider
class_alias(
'The\AliasClass',
'My\RealClass',
true
);
and
class_alias(
'The\AliasClass',
'My\Real'.'Class', // <-- break up the string
true
);
With the latter, PhpStorm will not pick up the My\RealClass and your "multiple definition" warning will cease. This is an ancient JavaScript trick to embed HTML in a string literal, by the way.
This warning has annoyed me for a long time. I believe the answers here saying there is a duplicate file somewhere is correct. The reason I am getting the warnings are due to the autocomplete file to give phpStorm a hint on how to find codeIgniter functions. If you are doing this also that is the reason for some of the warnings. The autocomplete file makes phpStorm think there are two different definitions. However, I like autocomplete more than I dislike the warnings so I guess I have to live with them.
This is the autocomplete I'm referring to:
IntelliJ IDEA 12 not finding CodeIgniter classes, throwing errors
Alternatives that work after a fashion, but aren't so good
marking the file B you don't want to be used by autocomplete as "plain" or excluded, leaving file A active: this will disable notifications in the file C, but will also make autocompletion no longer work for whatever is in file B. So if somewhere else you use something that's rightly in B, and maybe there you want to exclude A from autocompletion, you can't do that.
disable the inspection: this will also disable undefined class warnings, so if I make any typos in any class name, I'll only discover this after deployment (or from the fact that autocomplete stops working for that object).
"Don't report multiple class declaration potential problems" - this is very nearly good, but I don't like having "potential problems" ignored; what if I create a class with an unwittingly duplicated name that is in use somewhere else? Granted that I'll catch it (or phpunit will), but still.
The best I've found so far
The way to go for now, at least until a more focused configuration is available for PHPStorm (e.g. "Alternative Classes"), is to mark those notifications - and only those - as ignorable:
/* #noinspection PhpUndefinedClassInspection */
/**
* Verify an existing contract. Requires agent and supervisor.
*
* #param array $data
* #param Cliente $cli
* #param User $age
* #param User $sup
* #return Contratto
*/
private function contratto(
array $data,
/* #noinspection PhpUndefinedClassInspection */
Cliente $cli,
/* #noinspection PhpUndefinedClassInspection */
User $age,
/* #noinspection PhpUndefinedClassInspection */
User $sup
) {
Note that to disable notifications in the PHPDoc comment I had to add a directive before the comment; this did not disable the notifications for the three parameters.
In the future, I wish to be able to specify those in PHPStorm as
* #param array $data raw data for the contract
* #param \local\foobar\Cliente $cli customer opening the contract
private function contratto(
array $data,
/*\local\foobar\*/Cliente $cli,
or better still, explicitly use a new PHPdoc tag such as "#replaces". So PHPStorm would know that my class is the one not replaced. I'll also have to decorate my use's to specify the class I'll be actually using.
And run a search for "#noinspection PhpUndefinedClassInspection" throughout my code.
Another way
The above problems stem from the fact that I have a "master" Customer class which is overridden by a "local" modification for the foobar client, whose Customers have (say) a special method.
The "correct" way of doing this should be to declare a FoobarCustomer which is only employed by foobar's code, and is a child class of Customer. Of course this is only possible if the child class is in my code, not in the framework's, and also I may need some methods in the parent class to be protected rather than private, which may make this solution either impossible or needful of Reflection:
/**
* Verify an existing contract. Requires agent and supervisor.
*
* #param array $data
* #param FoobarCliente $cli
* #param FoobarUser $age
* #param FoobarUser $sup
* #return Contratto
*/
private function contratto(array $data, FoobarCliente $cli, FoobarUser $age...
I had similar problem and it was quite annoying one. I was using Yii2 framework and as it turned out at the end I have accidentally created en extra "vendor" folder and composer.json in the root of the project (not in the root of the app) so I ended up with that warning as phpStorm was confused which extension folder is the right one.
I've deleted extra vendor folder and it solved the problem.
Try delete duplicate declared libraries
Settings -> Languages & Frameworks -> PHP -> Include Path
I resolved this in my case by removing a more specific entry in my composer.json that included code by another more general entry
I have two libraries libA and libB.
libA contains a file Action.h
libB contains a file action.h
I want to generate doxygen documentation in the same output directory for both libraries. This directory is to be used in Windows, for which action.html and Action.html is unfortunately considered to be the same file. To prevent this clash, I wish to render the generated files unique by prepending their path names to them.
Therefore, I set FULL_PATH_NAMES to YES.
I expect to see something like libA_Action.html and libB_action.html when I generate the documentation, but I don't! I still see Action.html and action.html. Its as if the FULL_PATH_NAMES parameter does nothing at all. Do I also need to set some other parameter in the Doxyfile to make the FULL_PATH_NAMES parameter work correctly?
You're probably running doxygen twice - one time for each library. If that is the case, doxygen isn't aware of the fact that it might clash with an output from another run, so when it find an existing file, it assumes that it is leftover from a previous run, and overrides it.
Setting FULL_PATH_NAMES doesn't help, as doxygen has no idea that multiple libraries exist, so, as far as doxygen is concerned, the prefix is identical to all files, so even when you adding a force it, it adds nothing (That's probably a bug).
The solution to your problem is setting both libraries as inputs to the same doxygen project.
You can do it by setting INPUT to multiple folders in the configuration file:
INPUT = ...bla\Lib1 \
...bla\Lib2
I want to create a php Template in PhpStorm with has a comment block at the top with the usual info (author, creation date, class etc.) but also with a bunch of premade functions.
The purpose of this is that I want to make PHP Unit Class Template with the setup/teardown functions already coded, because these template are used for one project I don't expect they will change as the setups just set global which really should always be set up to make building the test easier (i.e. getting global scoped helpers).
I've tried creating the file templates however when I've copied the code into the template, any variable comes up as in input box when I go to create the file, which might be fine for me using but for someone who's using it for the first time they can screw up by filling in values for this-.
So I am wondering, how can I create a template in PhpStorm which has code in it?
You need to escape $ character which is used by Velocity template engine internally (has special meaning).
You can use ${DS} or \$ for that; so $this will become ${DS}this or \$this .
P.S. ${DS} is a safer choice overall as in some cases \$ may not work.
The official help page has it all explained: https://www.jetbrains.com/help/phpstorm/file-template-variables.html
In MediaWiki skin definitions, the BaseTemplate that gets extended has several attributes for creating links to other pages in the wiki, but I've got a situation where I need the path to the skin's directory, to pull some images used to create the UI. By default, that would just be /skins/mySkin/images/foo.png, by default but if someone changes the $wgStylePath variable, or renames the skin, that would be an issue. Is there an existing variable that has that URL build out, hidden somewhere in the BaseTemplate methods?
Yes, the SkinTemplate class, which contains the code to set up the template variables before executing the template, provides access to $wgStylePath via the 'stylepath' template variable.
When you subclass SkinTemplate to define your skin's main class, you are also expected to override the $stylename member variable, which specifies the subdirectory under which your skin's own stylesheets and images reside. (This would usually be the same as the name of your skin in lower case, but it doesn't have to be; it's perfectly fine to have, say, two related skins using images from the same directory.) This is also made available as a template variable, surprisingly named 'stylename'. So one way to specify an image path in your template would be something like:
<?php $this->text('stylepath') ?>/<?php $this->text('stylename') ?>/images/foo.png
Another way, (formerly) used e.g. by the Vector skin, is to use the getSkinStylePath() method from the Skin class (which is the superclass of SkinTemplate; it's kind of messy and tangled for historical reasons, but basically you can pretty much treat them as one class split into two files).
Update: As of MediaWiki 1.36, getSkinStylePath() has been deprecated. The recommended alternative, according to the release notes, is to "replace usages with the direct path to the resources."
To use it, you pass in the name of the file as a parameter, and the method automatically prepends $wgStylePath and $stylename to it (and appends $wgStyleVersion as a query string). Note that this is not a template method, so you have to escape and print the returned URL yourself:
<?php echo htmlspecialchars( $this->getSkin()->getSkinStylePath( 'images/foo.png' ) ) ?>
There's also a getCommonStylePath() method which does exactly the same thing, except that it uses the string "common" instead of $stylename.
Apparently this is the new way:
$this->getSkin()->getConfig()->get( 'StylePath' ) . '/SkinName/images/foo.png';
