Detailed Description

Represents the command line used to invoke a XUL application.

This may be the original command-line of this instance, or a command line remoted from another instance of the application.

DEFINITIONS: "arguments" are any values found on the command line. "flags" are switches. In normalized form they are preceded by a single dash. Some flags may take "parameters", e.g. "-url <param>" or "-install-xpi <param>"

UNDER_REVIEW This interface is intended to be frozen, but isn't frozen yet. Please use with care.

Member Function Documentation

long nsICommandLine::findFlag ( in AString  aFlag,
in boolean  aCaseSensitive 
)

Find a command-line flag.

Parameters:
aFlagThe flag name to locate. Do not include the initial hyphen.
aCaseSensitiveWhether to do case-sensitive comparisons.
Returns:
The position of the flag in the command line.
AString nsICommandLine::getArgument ( in long  aIndex)

Get an argument from the array of command-line arguments.

On windows, flags of the form /flag are normalized to -flag. /flag:param are normalized to -flag param.

On *nix and mac flags of the form --flag are normalized to -flag. --flag=param are normalized to the form -flag param.

Parameters:
aIndexThe argument to retrieve. This index is 0-based, and does not include the application name.
Returns:
The indexth argument.
Exceptions:
NS_ERROR_INVALID_ARGif aIndex is out of bounds.
boolean nsICommandLine::handleFlag ( in AString  aFlag,
in boolean  aCaseSensitive 
)

A helper method which will find a flag and remove it in one step.

Parameters:
aFlagThe flag name to find and remove.
aCaseSensitiveWhether to do case-sensitive comparisons.
Returns:
Whether the flag was found.
AString nsICommandLine::handleFlagWithParam ( in AString  aFlag,
in boolean  aCaseSensitive 
)

Find a flag with a parameter and remove both.

This is a helper method that combines "findFlag" and "removeArguments" in one step.

Returns:
null (a void astring) if the flag is not found. The parameter value if found. Note that null and the empty string are not the same.
Exceptions:
NS_ERROR_INVALID_ARGif the flag exists without a parameter
Parameters:
aFlagThe flag name to find and remove.
aCaseSensitiveWhether to do case-sensitive flag search.

Remove arguments from the command line.

This normally occurs after a handler has processed the arguments.

Parameters:
aStartIndex to begin removing.
aEndIndex to end removing, inclusive.
nsIFile nsICommandLine::resolveFile ( in AString  aArgument)

Resolve a file-path argument into an nsIFile.

This method gracefully handles relative or absolute file paths, according to the working directory of this command line.

Parameters:
aArgumentThe command-line argument to resolve.
nsIURI nsICommandLine::resolveURI ( in AString  aArgument)

Resolves a URI argument into a URI.

This method has platform-specific logic for converting an absolute URI or a relative file-path into the appropriate URI object; it gracefully handles win32 C:\ paths which would confuse the ioservice if passed directly.

Parameters:
aArgumentThe command-line argument to resolve.

Member Data Documentation

Number of arguments in the command line.

The application name is not part of the command line.

Definition at line 65 of file nsICommandLine.idl.

There may be a command-line handler which performs a default action if there was no explicit action on the command line (open a default browser window, for example).

This flag allows the default action to be prevented.

Definition at line 144 of file nsICommandLine.idl.

The type of command line being processed.

STATE_INITIAL_LAUNCH is the first launch of the application instance. STATE_REMOTE_AUTO is a remote command line automatically redirected to this instance. STATE_REMOTE_EXPLICIT is a remote command line explicitly redirected to this instance using xremote/windde/appleevents.

Definition at line 133 of file nsICommandLine.idl.

Definition at line 135 of file nsICommandLine.idl.

Definition at line 136 of file nsICommandLine.idl.

Definition at line 137 of file nsICommandLine.idl.

A window to be targeted by this command line.

In most cases, this will be null (xremote will sometimes set this attribute).

Definition at line 157 of file nsICommandLine.idl.

The working directory for this command line.

Use this property instead of the working directory for the current process, since a redirected command line may have had a different working directory.
