public class Ildasm
extends Task

Task to take a .NET or Mono -generated managed executable and turn it into ILASM assembly code. Useful when converting imported typelibs into assembler before patching and recompiling, as one has to do when doing advanced typelib work.

As well as generating the named output file, the ildasm program will also generate resource files `Icons.resources` `Message.resources` and a .res file whose filename stub is derived from the source in ways to obscure to determine. There is no way to control whether or not these files are created, or where they are created (they are created in the current directory; their names come from inside the executable and may be those used by the original developer). This task creates the resources in the directory specified by `resourceDir` if set, else in the same directory as the `destFile`.

This task requires the .NET SDK installed and ildasm on the path. To disassemble using alternate CLR systems, set the executable attribute to the name/path of the alternate implementation -one that must support all the classic ildasm commands.

Dependency logic: the task executes the command if the output file is missing or older than the source file. It does not take into account changes in the options of the task, or timestamp differences in resource files. When the underlying ildasm executable fails for some reason, it leaves the .il file in place with some error message. To prevent this from confusing the dependency logic, the file specified by the `dest` attribute is always deleted after an unsuccessful build.

Constructor Detail

### Ildasm

    public Ildasm()

Method Detail

### setResourceDir

    public void setResourceDir(java.io.File resourceDir)

  Set the name of the directory for resources to be created. We cannot control their names, but we can say where they get created. If not set, the directory of the dest file is used

### setExecutable

    public void setExecutable(java.lang.String executable)

  override the name of the executable (normally ildasm) or set its full path. Do not set a relative path, as the ugly hacks needed to create resource files in the dest directory force us to change to this directory before running the application. i.e use <property location> to create an absolute path from a relative one before setting this value.

  Parameters:
    `executable` -

### setEncoding

    public void setEncoding(Ildasm.EncodingTypes encoding)

  Select the output encoding: ascii, utf8 or unicode

  Parameters:
    `encoding` -

### setAssembler

    public void setAssembler(boolean assembler)

  enable (default) or disable assembly language in the output

  Parameters:
    `assembler` -

### setBytes

    public void setBytes(boolean bytes)

  enable or disable (default) the original bytes as comments

  Parameters:
    `bytes` -

### setDestFile

    public void setDestFile(java.io.File destFile)

  the output file (required)

  Parameters:
    `destFile` -

### setHeader

    public void setHeader(boolean header)

  include header information; default false.

  Parameters:
    `header` -

### setItem

    public void setItem(java.lang.String item)

  name a single item to decode; a class or a method e.g item="Myclass::method" or item="namespace1::namespace2::Myclass:method(void(int32))

  Parameters:
    `item` -

### setLinenumbers

    public void setLinenumbers(boolean linenumbers)

  include line number information; default=false

  Parameters:
    `linenumbers` -

### setMetadata

    public void setMetadata(boolean metadata)

  include metadata information

  Parameters:
    `metadata` -

### setProgressBar

    public void setProgressBar(boolean progressBar)

  show a graphical progress bar in a window during the process; off by default

  Parameters:
    `progressBar` -

### setQuoteallnames

    public void setQuoteallnames(boolean quoteallnames)

  quote all names.

  Parameters:
    `quoteallnames` -

### setRawExceptionHandling

    public void setRawExceptionHandling(boolean rawExceptionHandling)

  enable raw exception handling (default = false)

  Parameters:
    `rawExceptionHandling` -

### setShowSource

    public void setShowSource(boolean showSource)

  include the source as comments (default=false)

### setSourceFile

    public void setSourceFile(java.io.File sourceFile)

  the file to disassemble -required

  Parameters:
    `sourceFile` -

### setSrcFile

    public void setSrcFile(java.io.File sourceFile)

  alternate name for sourceFile

  Parameters:
    `sourceFile` -

### setVisibility

    public void setVisibility(java.lang.String visibility)

  This method sets the visibility options. It chooses one or more of the following, with + signs to concatenate them:

       pub : Public
       pri : Private
       fam : Family
       asm : Assembly
       faa : Family and Assembly
       foa : Family or Assembly
       psc : Private Scope

  e.g. visibility="pub+pri". Family means `protected` in C#;

  Parameters:
    `visibility` -

### execute

    public void execute()
                 throws BuildException

  do the work

  Overrides:
    `execute` in class `Task`
  Throws:
    `BuildException`
