I am trying to create a visual studio 2017 extension. More specifically, I want to extend IntelliSense to create light bulb suggestions and fixes. For that, I am trying to go through the syntax of .cshtml file (both markup and c# code), and parse it so that I can get stuff like values of the attributes and tag names, so that I know when to show the light bulbs.
I went through the documentation on MSDN site. I found out how I could get the light bulbs to show up at specific caret location using ITextBuffer and Snapshot for [ContentType = "text"]. But for my problem, I want the light bulb to show up based on values of attributes and like. So, I think I will have to work with [ContentType = 'code']. I couldn't find proper documentation for that. I found this article
https://designprincipia.com/writing-a-visual-studio-extension-to-automate-code-generation-with-roslyn/
It tells how you can show a light bulb when your caret is on a method name and make a class file with that method name. Now, this is for a C# file and uses the Roslyn APIs to get the syntax tree and sementic model of the C# code.
Problem Comes down to this
I have a .cshtml file and I want to get the syntax tree of the markup and C# code in it. And, I think I should be able to get it because the editor higlights the markup and C# code of the file differently. Thus, it must be parsing it. But I am not able to do this.
So, for my approach I am trying to get the syntax tree. I want to know how this can be done. Please, tell me if this the wrong direction and what else I can do.
PS: This is my first question so please tell me if I have left any information and also I am new to Razor so maybe I am missing something there.
Thanks a lot for your time.
This might be useful:
using System.Web.Razor;
using System.Web.Razor.Parser.SyntaxTree;
var host = new RazorEngineHost(new CSharpRazorCodeLanguage());
var engine = new RazorTemplateEngine(host);
var result = engine.ParseTemplate(new StringReader(<STRING>)));
result.Document.Children provides detailed recursive tree structure.

I've installed a mediawiki and imported an example page from Wikipedia. But the template is not shown properly. https://wordpress-251650-782015.cloudwaysapps.com/wiki/Cheeta
Any hint on what could be the cause?
You're most likely missing one or more required templates/Lua modules this template relies on. If you want to get all the required templates/modules you can get them via https://en.wikipedia.org/wiki/Special:Export by inserting the template name and ticking the box saying Include templates, and then importing the file generated from that via http://wordpress-251650-782015.cloudwaysapps.com/wiki/Speciale:Importa. However in most cases, except if you desperately want the exact look and feel its easier to write your one template, because Wikipedia templates get enormously complex
I am getting Class file editor : Source not found error for the classes in junit / hazelcast packages. Previously i got this error for all built in java classes. But after adding the Source zip file, i am able to see String.class and all. What i need to do for these classes. Please find the screenshot
Thanks in Advance!
Interestingly enough, your question contains all the concepts you need to know in order to answer it.
In order for your IDE to show you source code for any library you are using, the corresponding library needs to come with source code attached to it.
In other words: you managed to point your IDE to the ZIP file containing the source code for your JRE/JDK - thus your IDE knows what to show you when want to open up String.class
Now it seems that you are using other libraries as well. Maybe maybe, other libraries, have other, different source code ZIP files?!
Long story short: you need to add "source code" ZIPs for each and any additional library you are using and that you want to "peek into".
Within eclipse, you achieve that for example as described in that SO q/a. Side note: that is also something to keep in mind: you should do prior research before coming up with "new" questions. Especially when you are a beginner, you can be very sure that "your" question was asked here before.
this is one heck of a confusing question to ask so here it goes. Firstly, I'm not asking you to write me any code I just need help going in the right direction for what I'm trying to achieve here. Basically the task is this, I want to scan a select area of a web page's source code for changes and if something does change, I want to report it somewhere (like a console or something). However, I do not want just a notification of change, I also want what the change is/was. I've been looking into things like jsoup but I am still struggling to even find out what this is called.
Any pointers would be insanely appreciated. Thanks, Optimistic.
Here are some steps assuming this is from a node.js project:
Get the URL for the specific script file you're looking for a change in.
Using the request() module, fetch that URL.
Break the data up into lines (probably using .split()).
Find the specific line you are looking for either by counting line numbers of by searching for some representative text in that line.
Using some sort of search in that line (perhaps a regex), find the current value of the exact item in that line you are looking for.
Save the current value.
Then, at some future time, repeat this whole process and compare what you find to the previous value.
If this is being done from a browser instead of node.js, then use an Ajax call to retrieve the file. If the file is on another domain from your web page and that domain does not permit cross-origin requests, then you cannot solve this problem in an automated fashion from a browser in your own web page.
Here is how I would do it with Jsoup:
Document doc = Jsoup.connect(url).get();
String scriptCssQuery = "script"; // Tune this CSS query to find THE script you need.
Element script = doc.select(scriptCssQuery).first();
if (script != null) {
String scriptLines = script.html();
// Store the changing line somewhere and compare it to its previous value...
}
Im currently using SSRS-2008R2. I've an scenario where i have to maintain the External image as a logo for each reports we have. Not, only that, we have our custom date formats that what we should change according to the Date Type users define in an asp.net application.
There are lot of things we have to do on every report. Thats my problem.
Following is the one of them Im currently sharing as example :
Currently i maintain the following function for each reports i've:
Public Function GetLogoImage() As String
Dim ImageLogoURL As String
if Globals!ReportServerUrl is nothing then
ImageLogoURL = "http://localhost/ReportServer" + "?%2fImages%2fLogo"
else
ImageLogoURL = Globals!ReportServerUrl + "?%2fImages%2fLogo"
Return ImageLogoURL
End Function
I hope, i asked question clearly. Im newbie in SO.
Thank you in advance.
If you have a list of functions that you wish to apply to multiple reports and you're not willing to copy them to every single one of them, you can create an external library and then add it as a reference to every report.
This is quite simple to do and there's lot of documentation around the web.You can start here. You will, however, have to maintain this external library but if you have a lot of code, I personally think this is a much better solution.
If you want to have a predefined layout, you may want to consider having a master report and then include other reports as sub-report objects, but you'll lose some flexibility design wise.
Since the accepted answer is more of a comment and the link provided is broken, i'll provide my answer for people who might need a quick guide on how to use custom code in ssrs:
In Design view, right-click the design surface outside the border of the report and click Report Properties.
Click Code.
In Custom code, type the code. Errors in the code produce warnings when the report runs.
Once you press ok, to call the function that you saved you just need to right click on a cell, select "Expression" and paste in the following string: Code.GetLogoImage

I have a question about how to render the sql schema with fluent nhibernate.
I have searched alot and used a couple of things but i dont know how to render it. I´m only building the ground of my website, the core. And now i want to create the database from my mappings. How do i do that? Is it with testrunning or what?
If i build the solution i don´t get any sql file i have also tried export it to hbm files to use schema tool export but dont get it to work.
have tried
Fluent NHibernate (1.2.0.712) export mappings to HBM not working / not respecting conventions
and
https://stackoverflow.com/questions/5244257/build-schema-with-fluent-nhibernate
and alot other links.
What do i have to do to get the sql file? every site give almost the same code but they don´t tell how to render it. How to execute the process to retrieve the file..
can anyone tell me? i can build it by my self but i want to try this function!
best regards
You can create the database using the SchemaExport.Create method:
// this NHibernate tool takes a configuration (with mapping info)
// and exports a database schema from it
new SchemaExport(config)
.Create(true, true);
If you want to see the generated SQL, you can use the ShowSql method, but this is not required to create the database.
_sessionFactory = Fluently.Configure()
.Database(SQLiteConfiguration.Standard
.UsingFile(SqliteDatabaseFullPath())
// Display generated SQL in Output window
.ShowSql()
)
...
It's been my experience with NHibernate that it's almost always best to start with a working example, so I suggest you get the FirstAutomappedProject sample project that is part of the FNH source. This will give you all the pieces you need.
Probably easiest to download the zip file (button on the upper left) which includes all the FNH source code, and look in the "src" folder for the examples.
