Method Detail

expandAtFiles

public static com.google.common.collect.ImmutableList<String> expandAtFiles(Iterable<String> args,
                                                                            com.google.common.collect.ImmutableMap<CellName,AbsPath> cellMapping)

Expand AT-file syntax in a way that matches what args4j does. We have this because we'd like to correctly log the arguments coming from the AT-files and there is no way to get the expanded args array from args4j.

In addition to files passed using a regular @ syntax, this method also extracts command line arguments from AT-file syntax files passed via --flagfile command line option.

Parameters:

args - original args array

cellMapping - a map from cell names to their roots

Returns:

args array with AT-files expanded.

filterArgs

public static com.google.common.collect.ImmutableList<String> filterArgs(List<String> args,
                                                                         com.google.common.collect.ImmutableSet<String> optionsToSkip)

Drops options from the args array.

Parameters:

args - args array.

optionsToSkip - if args contains an element from this array skip the element and the element immediately after it.

Returns:

filtered args array
