Class Ildasm

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.

Method Detail

execute

public void execute()
do the work

Throws: BuildException

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(File destFile)
the output file (required)

Parameters: destFile

setEncoding

public void setEncoding(Ildasm.EncodingTypes encoding)
Select the output encoding: ascii, utf8 or unicode

Parameters: encoding

setExecutable

public void setExecutable(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

setHeader

public void setHeader(boolean header)
include header information; default false.

Parameters: header

setItem

public void setItem(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

setResourceDir

public void setResourceDir(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

setShowSource

public void setShowSource(boolean showSource)
include the source as comments (default=false)

setSourceFile

public void setSourceFile(File sourceFile)
the file to disassemble -required

Parameters: sourceFile

setSrcFile

public void setSrcFile(File sourceFile)
alternate name for sourceFile

Parameters: sourceFile

setVisibility

public void setVisibility(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
