<ilasm> Task

# <ilasm>

Compiles ILASM programs.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
output | file | Specifies the name of the output file created by the compiler. | True
target | string | Specifies which output type should be generated. | True
alignment | int | Instructs the compiler to set the FileAlignment value in the PE header. | False
base | int | Instructs the compiler to set the ImageBase value in the PE header. | False
clock | bool | Specifies whether or not the compiler should measure and report the compilation times. | False
debug | bool | Specifies whether or not the compiler should generate debug information. | False
error | bool | Specifies whether or not the compiler should attempt to create a PE file even if compilation errors have been reported. | False
flags | int | Instructs the compiler to set the Flags value in the CLR header. | False
keyfile | file | Instructs the compiler to generate a strong signature of the PE file. | False
keysource | string | Instructs the compiler to generate a strong signature of the PE file. | False
listing | bool | Specifies whether or not the compiler should type a formatted listing of the compilation result. | False
rebuild | bool | Instructs NAnt to recompile the output file regardless of the file timestamps. | False
resourcefile | file | Instructs the compiler to link the specified unmanaged resource file into the resulting PE file. | False
subsystem | int | Instructs the compiler to set the Subsystem value in the PE header. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False
verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False

### Framework-configurable parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
exename | string | The name of the executable that should be used to launch the external program. | False
managed | ManagedExecution | Specifies whether the external program should be treated as a managed application, possibly forcing it to be executed under the currently targeted version of the CLR. | False
useruntimeengine | bool | Deprecated. Specifies whether the external program is a managed application which should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <sources>

Specifies the set of source files to compile.

#### </sources>

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

When passed to an external application, the argument will be quoted when appropriate. This does not apply to the `line` parameter, which is always passed as is.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False
file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False
if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False
line | string | List of command-line arguments; will be passed to the executable as is. | False
path | <path> | The value for a PATH-like command-line argument; you can use `:` or `;` as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False
unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False
value | string | A single command-line argument; can contain space characters. | False

### Nested Elements:

#### <path>

Sets a single command-line argument and treats it like a PATH - ensures the right separator for the local platform is used.

#### </path>

### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>

### Examples

- Compiles `helloworld.il` to `helloworld.exe`.

      <ilasm target="exe" output="helloworld.exe" debug="true">
          <sources>
              <include name="helloworld.il" />
          </sources>
      </ilasm>

### Requirements
