ArmaFiles

A collection of utlities for dealing with Arma files in Java.

Usage

PBO

For accessing a PBO you have to create a new PBO-object from a file pointing to the PBO on the hard drive

PBO pbo = new PBO(new File("<your path here>"));

By creating the PBO it will also detect all PBOEntrys inside it that correspond to the single files inside it. You can get those either via pbo.getEntries() or you can search them by name via pbo.getEntry("<name of the file>"); A PBOEntry can then be used to access the corresponding file's content by providing an InputStream to it. In order to get this stream you have to call entry.toStream() which will give you a PBOInputStream that can be used as any other input stream.

Config

In order to read in a config file you have to use one of the static methods provided by ConfigClass:

ConfigClass cfgCl = ConfigClass.fromRapifiedFile(new ByteReader(<InputStream to the file>));
ConfigClass cfgCl2 = ConfigClass.fromTextFile(new TextReader(<InputStream to the file>));

If you are reading the config out of a PBO the needed InputStream can be a PBOInputStream as returned by entry.toStream().

So when do you need to use which function? Simple: If the config file that should be read is binarized/rapified (e.g. config.bin in addons) you have to use fromRapifiedFile whereas fromTextFile is the right choice if you're reading the config in from a plain text file. Note though that the input-file for the latter case has to be fully preprocessed! All entries in a config file are stored as a ConfigClassEntry which can either be a SubclassEntry, an ArrayEntry or a ValueEntry (String, Float, Long). For dealing with a CfgFunctions in particular there's a corresponding class for it that can be created. it will offer access to all functions defined in it with their set attributes.

CfgFunctions cfg = new CfgFunctions(cfgCl);
cfg.init();
HashSet<String, ConfigFunction> definedFunctions = cfg.getDefinedFunctions();

Example

In this example all functions defined inside a mod-folder are being extracted. It is copied from https://github.com/Krzmbrzl/SQDev

for (File currentFolder : modFolders) {
	if (modName != null && !currentFolder.getName().toLowerCase().equals(modName)) {
		continue;
	}

	File addonFolder = new File(currentFolder, "addons");

	for (File currentAddon : addonFolder.listFiles()) {
		if (currentAddon.getName().toLowerCase().endsWith(".pbo")) {
			try {
				PBO pbo = new PBO(currentAddon);
				ConfigClass config = null;

				PBOEntry configEntry = pbo.getEntry("config.bin");
				if (configEntry != null) {
					config = ConfigClass.fromRapifiedFile(new ByteReader(configEntry.toStream()));
				} else {
					configEntry = pbo.getEntry("config.cpp");
					if (configEntry == null) {
						configEntry = pbo.getEntry("config.hpp");

						if (configEntry == null) {
							// there seems to be no config-entry for this mod
							continue;
						}

						config = ConfigClass.fromTextFile(new TextReader(configEntry.toStream()));
					}
				}

				ConfigClass functionsConfig = config.getSubclass(CfgFunctions.NAME, false);

				if (functionsConfig != null) {
					CfgFunctions cfg = new CfgFunctions(functionsConfig);
					cfg.init();

					for (ConfigFunction current : cfg.getDefinedFunctions().values()) {
						functions.add(Function.from(current));
					}
				}
			} catch (IOException | RapificationException | ConfigException e) {
				e.printStackTrace();
			}
		}
	}
