I want to generate c# asp.net core razor pages with many projects: Application, Domain, Infrastructure, Core etc.
I would like to know if Telosys is extensible to allow a custom console program to be called with arguments: , so this program can do some code merges in order to preserve possible additions/changes to the code a developer did since the previous code generation?
C# can have some directives called #region to partition the code and these will be "regenerate only regions" and outside these regions the developer can put his own code. We need to preserver his code.
C# Partial classes and methods can also help.
I want to have capability to merge newly re-generated code (e.g. entity class - I can add some properties or change some property name, type, annotations, tags etc.) into previously generated entity class. This could be done by creating #region .... #endregion where the code can be regenerated into and all the code that is outside these regions should be preserved. See: efg.loresoft.com/en/latest/regeneration So I would like to know if there would be a way to temporarily generate files in a TMPGEN folder and allow some "merge program to run" that will mege new code with previously generated code (with some code added by the developer) previously determining if merge is needed (compare hashes)
This is the code from EntityFrameworkCore.Generator tool that merges existing regions https://github.com/loresoft/EntityFrameworkCore.Generator..EntityFrameworkCore.Generator.Core/Templates/CodeTemplateBase.cs has the protected virtual method:
void MergeOutput(string fullPath, string outputContent) show that fullPath is an existing file and outputContent is the result of parsing the template (new content). RegionParser uses these namespaces: Microsoft.CodeAnalysis.CSharp; and Microsoft.CodeAnalysis.CSharp.Syntax;
so I need to user c# console application to user this preserver region code.
Thanks,
Rad
Yes, Telosys is extensible by using specific Java classes loaded in the template context with $loader
See : Is it possible in a Telosys template to call a function created specifically?
So, you just have to create a Java class to launch any Shell command
For example, see : How to get java getRuntime().exec() to run a command-line program with arguments?

I need to implement a custom ResultHandler but I am confused about how to actually integrate my custom class into the software package.
I have read this: http://elki.dbs.ifi.lmu.de/wiki/HowTo/InvokingELKIFromJava but my question is how are you meant to implement a custom result handler such that it shows up in the GUI?
The only way I can think of doing it is by extracting the elki.jar package and manually inserting my custom class into the source code, and then re-jarring the package. However I am fairly sure this is not the way it is meant to be done.
Also, in my resulthandler I need to output all the rows to a single text file with the cluster that each row belongs to displayed. How tips on how I can achieve this?
There are two questions in here.
in order to make your class instantiable by the UIs (both MiniGUI and command line), the classes must implement our Parameterization API. There are essentially two choices to make your class instantiable:
Add a public constructor without parameters (the UI won't know how to set your parameters!)
Add an inner static class Parameterizer that handles parameterization
in order to add your class to autocompletion (dropdown menu), the classes must be discovered by the MiniGUI/CLI/other UIs. ELKI uses two methods of discovery:
for .jar files, it reads the META-INF/elki/interfacename service files. This is a classic service-loader approach; except that we also allow ordering instances.
for directories only, ELKI will also scan for all .class files, and inspect them. This is mostly meant for development time, to avoid having to update the service files all the time. For performance reasons, we do not inspect the contents of .jar files; these are expected to use service files.
You do not need your class to be in the dropdown menu - you can always type the full class name. If this does not work, adding the name to the service file will not help either, but ELKI can either not find the class at all, or cannot instantiate it.
There is also a tutorial on implementing a custom result handler, but it does not discuss how to add it to the menu. In "development mode" - when having a folder with .class files - it will show up automatically.
I want to call the API of uima-text-segmenter https://code.google.com/p/uima-text-segmenter/source/browse/trunk/INSTALL?r=22 to run an example.
But I don`t know how to call the API...
the readme said,
With the DocumentAnalyzer, run the following descriptor
`desc/textSegmenter/wst-snowball-C99-JTextTilingAAE.xml` by taking the
uima-examples data as input.
Could anyone give me some code which could be run directly in main func for example?
Thanks a lot!
Long answer:
The link describes how you would set up the application from within the Eclipse UIMA environment. This sort of set-up is typically targeted at subject matter specialists with little or no coding experience. It allows them to work (relatively fast) with UIMA in a declarative way: all data structures and analysis engines (computing blocks within UIMA) are declared in xml (with a GUI on top of it), after which the framework takes care of the rest. In this scenario, you would typically run a UIMA pipeline using a run configuration from within Eclipse (or the included UIMA pipeline runner application). Luckily, UIMA allows you to do exactly the same from code, but I would recommend using UIMAFit (http://uima.apache.org/d/uimafit-current/tools.uimafit.book.html#d5e137) for this purpose instead of of UIMA, as it bundles lots of useful things and coding shortcuts.
Short answer:
Using UIMAFit, you can call Factory methods that create CollectionReader (read input), AnalysisEngine (process input) and Consumer objects (write/do other stuff) from (third-party provided) XML files. Use these methods to construct your pipeline and the SimplePipeline class to run it. To extract the data you need, you would manipulate the CAS object (containing your data) in a Consumer object, possibly with a callback. You could also do this in a Analysis Engine object. I recommend using DKPro's FeaturePathFactory (https://code.google.com/p/dkpro-core-asl/source/browse/de.tudarmstadt.ukp.dkpro.core-asl/trunk/de.tudarmstadt.ukp.dkpro.core.api.featurepath-asl/src/main/java/de/tudarmstadt/ukp/dkpro/core/api/featurepath/FeaturePathFactory.java?spec=svn1811&r=1811) to quickly access the feature you are after.
Code examples:
http://uima.apache.org/d/uimafit-current/tools.uimafit.book.html#d5e137 contains examples, but they all go in the opposite direction (class objects are used in the factory methods, instead of XML files - XML is generated from these classes). Take a look at the UIMAFit API to find the method you need, AnalysisEngineDescription from XML for example: http://uima.apache.org/d/uimafit-current/api/org/apache/uima/fit/factory/AnalysisEngineFactory.html#createEngineDescriptionFromPath-java.lang.String-java.lang.Object...-
Does anybody know how to create his own models and controllers in Orchard-based projects? I have an empty project and a pack of screenshots for pages, but I don't know with what to begin. If it is possible, please show an example.
Thanks.
You should start off at the documentation page. There is an 'Extending Orchard' section which walks you through how to create a module, with data access, content parts, and content fields.
Use the command line to generate the module using the code generation module
Documentation here
Then install the Code Generation Extensions from Piotr and follow the instructions on his blog. http://www.szmyd.com.pl/blog/generating-orchard-content-parts-via-command-line
Module adds an Orchard command-line command “codegen part”. It’s
syntax is as follows:
codegen part [/Properties:]
For example:
codegen part Modules.Shop ProductPart /Properties: Name:string,
Price:int
Properties is an optional parameter, so if you’d like to create an
empty part you can just write
codegen part Modules.Shop ProductPart
The command creates a handler, driver, model, record, display and
editor shapes and updates the Placement.info file with default
Content:before placement for your part shape. If you provide
/Properties parameter, the model, record and editor shapes will be
filled with appropriate code accordingly.
I have been using CodeDom to do some code generation. It works great, but I haven't found a way to include the generated source code files in a project. I started using T4 and the T4Toolbox to generate code because it supports integration with project files.
Does anyone know if CodeDom supports this functionality too? I'd consider taking a second look at CodeDom if it only supported this one feature.
Here is an example of how I make a source code file with CodeDom:
protected void CreateSourceFile(CodeCompileUnit codeCompileUnit,
string fileName,
out string fileNameWithExtension)
{
fileNameWithExtension = string.Format("{0}.{1}",
fileName,
CodeProvider.FileExtension);
var indentedTextWriter =
new IndentedTextWriter(new StreamWriter(fileNameWithExtension,
false),
TabString);
CodeProvider.GenerateCodeFromCompileUnit(codeCompileUnit,
indentedTextWriter,
new CodeGeneratorOptions());
indentedTextWriter.Close();
}
That works fine but it just outputs the file to the hard drive somewhere (probably bin folder).
Here is a second example of some code I use with T4, this one specifies the output as part of the project the template is transformed in:
public class RDFSClassGenerator : Generator
{
private readonly string rootNamespace;
private readonly string ontologyLocation;
public RDFSClassGenerator(
string rootNamespace,
string ontologyLocation)
{
this.rootNamespace = rootNamespace;
this.ontologyLocation = ontologyLocation;
}
protected override void RunCore()
{
XElement ontology = XElement.Load(ontologyLocation);
var service = new RDFSGeneratorService(ontology);
foreach (MetaClass metaClass in service.MetaClasses)
{
var rdfsClassTemplate = new RDFSClassTemplate(rootNamespace, metaClass);
rdfsClassTemplate.Output.File = "Domain/" + metaClass.Name + ".cs";
rdfsClassTemplate.Render();
}
}
}
So the T4 code will output the file into the "Domain" folder of my project. But the CodeGen stuff just outputs the file on disk and doesn't update the project file.
Here is a visual:
Yes, it can. Here is how: http://www.olegsych.com/2009/09/t4-and-codedom-better-together/
Short answer is no, but I could be wrong (ever try to prove a negative?)
Your question was a little confusing as CodeDom isn't exactly equitable with T4. T4 templates are a convenient way of generating code files the same way, for example, asp.net generates HTML files, mixing text and code that gets executed to generate a file that is then interpreted by something else (such as a compiler or a browser). CodeDom is usually used to generate assemblies at runtime rather than files, although you can do it (as you have discovered).
While T4 makes it easy to add files to the solution, you can do this with CodeDom as well. I don't believe it supports interaction with the solution directly, but you can manage this using EnvDTE, or the automation model for Visual Studio.
The problem with this is that the automation model isn't easy to work with. EnvDTE is a wrapper around COM classes, which is always fun to code against. Also, you have to be careful when attempting to get the object. The naive implementation will get the object from the first instance of Visual Studio loaded. You have to poll the Running Object Table to find the current instance. Once you have it, you must deal with searching through the dte for the location you're looking for, deal with source control, locked files, etc etc.
Working with it, you start to learn why T4 was created in the first place.
The question you have to ask yourself is, "Does CodeDom give me enough that T4 doesn't to make up for all its shortcomings?"
I'm trying to run codeanalysis on an assembly that contains an entity model (edmx file). In project properties I have checked the "Suppress results from generated code" option, but I am still getting a lot of CA errors pertaining to the auto-generated EF code.
Has anyone experienced this? And is there a work-around?
Just put the attribute on your class definition.
But how to do it, since your file can get overridden any time. Use a separate file, since all generated classes are partial classes. Open a separate file, and write something like:
[GeneratedCode("EntityModelCodeGenerator", "4.0.0.0")]
public partial class YourEntitiesContextName : ObjectContext
{
}
This will skip code analysis on your particular generated class. StyleCop for instance is more smart and doesn't touch files that have .designer/.generated part in their name or regions that have generated word in their name.
Well, "Suppress results from generated code" really means "Don't look at types with GeneratedCodeAttribute". EF's code generator hasn't added this, historically (though I've suggested it to the team). But you can add it if you use custom T4.
