how to config Intellij Idea live template's applicable context? - intellij-idea

I want to create a live templates group for my custom file type, but when i pick a applicable context, there are a list of kind of file type or language but my custom file type.
Is the list predefined and can not extend?

The available context types depend on the enabled plugins. It says so (and not much more) here in the Jetbrains help page: https://www.jetbrains.com/help/idea/2016.3/live-templates-2.html
If your custom file already has a plugin, maybe all you have to do is add it. For example adding the plugin Perl adds Perl5 to the list.
Otherwise you need to look into how to create an extension. More on that here: http://www.jetbrains.org/display/IJOS/Writing+Plug-ins
Good luck!

How to add an underscore mixin library to WebStorm?

In my work, we have a file with utilities functions that are extended in _.mixin() function at runtime. No, I cannot change the framework, because the solution would be to separate those function from _.mixin() and make them and indepent module, that would be the best.
Either way, my problem is that I cannot link this file, with all the extended functions in WebStorm, so I always see Unresolved function or method warning
Yes I have tried to add the file in the Library tab under Libraries & Framework preferences. And it did nothing.
So my question is, It is possible to WebStorm (or other Atlassian software) to link a file with several functions that will be extended with Underscore.js _.mixin() function to show up in Autocomplete?
Thanks, in advance
Adding the file to JavaScript libraries won't help here. _.mixin() dynamically adds passed utility functions to _ object, it's not possible to resolve such dynamically generated stuff during static code analysis unless a special treatment for the certain functions is provided. And WebStorm doesn't provide any special support for _.mixin().

Is it possible to use live-templates as file templates?

In the intellij products I'm very fond of the live-templates. I wonder if it is possible to use the same syntax for file templates, e.g. formatting a variable to snake- or camel-camese, defining a starting cursor position and so on.
Unfortunately you cannot use the same functions/macros available in Live Templates in File Templates.
File Templates use Apache Velocity template language. It allows some Java(?) simple methods to be run on variables (e.g. #set($class_start = $class.substring(0,1).toUpperCase())). Quite possible that more complex methods will work as well.
UPDATE (2017/01/13):
As of 2016.1 (or perhaps 2016.2) version it's now possible to use some Live Templates in File Templates as well (by checking Enable Live Templates checkbox for that File template). I'm not 100% sure if it will do the requested here thing (not tested myself).
Syntax example: #[[ $MY_VARIABLE$ $END$ ]]#

How to maintain different file headers per project in IntelliJ?

IntelliJ allows you to configure the "File and Code Templates" in Settings.
This is a global setting, however I want different templates depending on which project I am working on (for example there will be different #author tags if its commercial / open source work, and version information varies by project).
Eclipse manages this on a per-workspace basis; how can I achieve the same thing in IntelliJ IDEA?
Unfortunately per project templates are not supported in IntelliJ IDEA. I recommend you comment-on/vote-for/track the feature request Make file templates per-project. (See UPDATE about this feature request below)
A few workarounds you can try...
Create a File Template for each project. Then when you create a new class, use the project's template rather than the standard "Java class" template. It will clutter up your template list a bit, and you have to remember to change from the default template when creating a new class (remember than inline search is available in the new class dialog when setting the type). But it is workable.
The copyright settings are done on a per project basis. Sometimes a need for a specific header can be met using the copyright utility (even if it is not an actual copyright statement). The options are pretty good for determining where it gets placed. The one shortcoming will be that while you can configure it to be a comment just before the class declaration, you can only configure to be a block comment or inline comment, not a javadoc comment.
Finally, a last option would be to write a live template for each project with the header information. Then after you create a class use the proper one to place the header information.
Hopefully those things will help while we wait for the feature to get implemented.
UPDATE
The above mentioned feature request to allow for file templates to be saved on a per project basis has been implemented in IDEA v14.1. It is currently (Feb 2015) available as an EAP (i.e. beta). It is scheduled for release at the end of Q1 2015.

Eclipse: Project nature benefits, reading project & plugins settings

So far I have two short questions:
1) What precisely are the benefits of creating custom nature?
2) Is it possible to somehow programmatically read files in [project]/.setting or [workspace]/.metadata/.plugins?
I'm using Eclipse Helios (3.6).
Ad 1. I've read that you can't have two natures ofthe same set, that you can use it to associate certain perspectives/tools (ex. builder) with it but well.. anyting else I can't do easily without nature? Ex. I can easily add a builder by modifying an IProject variable.
Ad 2. I tried to find a way to read project specific settings or plugin settings but failed. No specs, different file types, inconsistent XML tags... Is it at all possible without parsing them manually?
Thanks for your help!

Think of a nature as a flag. All project-related functionality in Eclipse is triggered by natures. Project properties pages, context menu items, etc. appear based on presence of natures. Third parties can check for presence of nature to tell if the project is of certain "type". A nature also has install/uninstall methods. This gives you a convenient place to implement all actions that need to happen on the project when your technology is enabled. Why is that convenient? Because a third party can simply add the nature without knowing what else is necessary to configure and your code takes care of the rest.
Plugins write to [project]/.setting or [workspace]/.metadata/.plugins locations in different ways. The file formats are never documented as they aren't meant to be manipulated directly. Some plugins re-use the common ProjectScope and InstanceScope classes to read/write the data. Some read/write on their own. I would start with what information you are trying to read, figure out which plugin it belongs to and then see if there is public API in that plugin for accessing that information. Reading these settings directly is almost never going to be the correct approach.

Create a custom file extension in VB 2008

I have been doing a lot of searching on the web and cant seem to find a clear way of creating a custom file extension. I know to associate the file extension to a certain program, but how do create a format for the custom file extension?
You can do that as well through setup application as described in Walkthrough: Deploying a Windows-based Application, and you can pick any extension you like. I prefer to use abbreviation created from application name, and try to find if this extension is not in use. If extension was in use, then old reference (link between file type and application) will be broken. Use of 4 characters extensions will help with better chance of extension to be unique.
