The mxmlc and compc compilers take many options. The options are listed in the help which you can view with the help option, as the following example shows:

mxmlc -help

This displays a menu of choices for getting help. The most common choice is to list the basic configuration options:

mxmlc -help list

To see advanced options, use the list advanced option, as the following example shows:

mxmlc -help list advanced

To see a list of entries whose names or descriptions include a particular String, use the following syntax:

mxmlc -help pattern 

The following example returns descriptions for the external-library-path, library-path, and runtime-shared-libraries options:

mxmlc -help list library

For a complete description of mxmlc options, see About the application compiler options. For a complete description of compc options, see About the component compiler options.

Many command-line options, such as show-actionscript-warnings and accessible, have true and false values. You specify these values by using the following syntax:

mxmlc -accessible=true -show-actionscript-warnings=true

Some options, such as source-path, take a list of one or more options. You can see which options take a list by examining the help output. Square brackets ([ ]) that surround options indicate that the option can take a list of one or more parameters.

You can separate each entry in a list with a space or a comma. The syntax is as follows:

-var val1 val2

or

-var=val1, val2

If you do not use commas to separate entries, you terminate a list by using a double hyphen, as the following example shows:

-var val1 val2 -- -next_option 

If you use commas to separate entries, you terminate a list by not using a comma after the last entry, as the following example shows:

-var=val1, val2 -next_option 

You can append values to an option using the += operator. This adds the new entry to the end of the list of existing entries rather than replacing the existing entries. The following example adds the c:/myfiles directory to the library-path option:

mxmlc -library-path+=c:/myfiles
