HMLanguages ​

This library allows you to convert between CLNG, DITL, DLGE, LOCR, and RTLV to JSON and vice-versa.
On how to add the library to your project, see the installation page.

The entire library can be included in a file through #include <TonyTools/Languages.h>.

There is a tool which implements this library in full. The source can be used as a reference implementation.

This page will go into detail about the formats, naming conventions used by the tool, and more. Technical details, such as structure of the raw files, will be in collapsible sections (but these have yet to be added).

Language Maps ​

HMLanguages uses something called a "language map" (langmap for short) when converting and rebuilding files. These aren't always required to be explicitly defined by the user, and most of the time can be left to the default ones. They're used for outputting files, and for some files don't need to be exact.

The first table below shows how each file type uses the language map, the second table shows the default language map for each version alongside a description of their source.

Figure 2: Table of game versions and their default language maps

Hash List ​

Work has been started on various hash lists that can be optionally loaded by the library. It provides:

• DLGE soundtags and switch cases.
• LINE hashes

You can download the latest version here.

A custom binary format is used to store these, more information on this can be seen below.

Format ​

The format is quite simple and can be described by a couple structures.

// This is the main file
struct HashList {
    uint32_t            magic;      // 0x484D4C41 'ALMH'
    uint32_t            version;    // Hash list version
    uint32_t            checksum;   // CRC32 checksum of the rest of the data
    HashListSection     soundtags;  // Soundtags
    HashListSection     cases;      // Switch cases
    HashListSection     lines;      // LINE hashes
}

struct HashListSection {
    uint32_t        nEntries;           // Number of entries
    HashListEntry   entries[nEntries];  // The actual entries
}

// We store the hash so we don't have to calculate this
// when loading the hash list for speed.
struct HashListEntry {
    uint32_t    hash;   // The CRC32 hash
    const char* string; // The original string (null terminated)
}

// This is the main file
struct HashList {
    uint32_t            magic;      // 0x484D4C41 'ALMH'
    uint32_t            version;    // Hash list version
    uint32_t            checksum;   // CRC32 checksum of the rest of the data
    HashListSection     soundtags;  // Soundtags
    HashListSection     cases;      // Switch cases
    HashListSection     lines;      // LINE hashes
}

struct HashListSection {
    uint32_t        nEntries;           // Number of entries
    HashListEntry   entries[nEntries];  // The actual entries
}

// We store the hash so we don't have to calculate this
// when loading the hash list for speed.
struct HashListEntry {
    uint32_t    hash;   // The CRC32 hash
    const char* string; // The original string (null terminated)
}

API ​

External programs have to load the hash list manually. Below are the functions that do this.

// All functions and structs below are in the
// TonyTools::Language::HashList namespace.

// Holds the status information about the hash list.
// Returned from the "GetStatus" function.
struct Status {
    bool loaded;
    uint32_t version;
};

// Loads the hash list from a vector comprised
// of the hash list file data.
// Returns if it was successful or not.
bool Load(std::vector<char> data);

// Same as above, but takes a pointer and
// size of the data.
bool Load(const char* ptr, uint32_t size);

// Clears the currently stored hash list.
void Clear();

// Gets the current status of the hash list.
Status GetStatus();

// Gets the LINE hash from a given value.
// Returns the zero-padded, 4-byte, string of the hash,
// or the input if it is not found.
std::string GetLineHash(std::string value);

// Gets the LINE from a given hash.
// Returns the LINE of the hash,
// otherwise the zero-padded, 4-byte, string of the hash.
std::string GetLine(uint32_t hash);

// All functions and structs below are in the
// TonyTools::Language::HashList namespace.

// Holds the status information about the hash list.
// Returned from the "GetStatus" function.
struct Status {
    bool loaded;
    uint32_t version;
};

// Loads the hash list from a vector comprised
// of the hash list file data.
// Returns if it was successful or not.
bool Load(std::vector<char> data);

// Same as above, but takes a pointer and
// size of the data.
bool Load(const char* ptr, uint32_t size);

// Clears the currently stored hash list.
void Clear();

// Gets the current status of the hash list.
Status GetStatus();

// Gets the LINE hash from a given value.
// Returns the zero-padded, 4-byte, string of the hash,
// or the input if it is not found.
std::string GetLineHash(std::string value);

// Gets the LINE from a given hash.
// Returns the LINE of the hash,
// otherwise the zero-padded, 4-byte, string of the hash.
std::string GetLine(uint32_t hash);

API Overview ​

HMLanguages exposes a C++ API to allow conversion and rebuilding of file types, the individual functions will be laid out for the specific file types in the formats section below, but here, we shall go over two important constructs.

Version Enum ​

This is used by virtually all file types, and is mainly used for getting the default language map. Some formats may have version specific quirks or it is required for ResourceLib.

The enum can be seen below, (0 and 1 are reserved for Hitman: Absolution and the 2016 Alpha):

// This is in the TonyTools::Language namespace
enum class Version : uint8_t
{
    H2016 = 2,
    H2,
    H3
};

// This is in the TonyTools::Language namespace
enum class Version : uint8_t
{
    H2016 = 2,
    H2,
    H3
};

Return Values ​

When using functions that convert a raw file + .meta.json to a HML JSON string, they return std::string.

If the library fails to convert a file, an error will be output to stderr and the function will return an empty string.

This can be checked like so:

std::string converted = ...;

if (converted.empty())
    // do something

std::string converted = ...;

if (converted.empty())
    // do something

When using functions that rebuild a HML JSON string to the raw file + .meta.json, they return a struct that can be seen below:

// This is in the TonyTools::Language namespace
struct Rebuilt
{
    std::vector<char> file; // contains the raw file bytes
    std::string meta;       // contains the JSON string of the .meta.json
};

// This is in the TonyTools::Language namespace
struct Rebuilt
{
    std::vector<char> file; // contains the raw file bytes
    std::string meta;       // contains the JSON string of the .meta.json
};

If the library fails to rebuild a file, an error will be output to stderr and an empty struct will be returned.

This can be checked like so:

TonyTools::Language::Rebuilt rebuilt = ...;

if (rebuilt.file.empty() || rebuilt.meta.empty())
    // do something

TonyTools::Language::Rebuilt rebuilt = ...;

if (rebuilt.file.empty() || rebuilt.meta.empty())
    // do something

Formats ​

The following sections will outline the formats, specifically their HMLanguages JSON representation alongside a description of how they work. These sections also include how to use HMLanguages to convert and rebuild these file types.

The JSON representations will not be complete, but, will have enough detail as required. They will have certain elements omitted, this will be indicated with an ellipsis (...).

This library includes schemas in the output files, these have been omitted on this page, but links to the schemas are included.

But before we start, it is recommended to read the glossary first to become familiar with some terms used.

CLNG ​

aka DialogCascadingLanguageDependencies

Not much is actually know about this file type, other than it corresponds to the current language map in the game version. HMLanguages can convert the file to an assumed representation (as the languages just have a 0x00 byte or a 0x01 byte which is presumed to be a boolean).

JSON Representation ​

Schema

{
    "hash": "...",
    "languages": {
        "xx": false,
        "en": false,
        "fr": true,
        ...
    }
}

{
    "hash": "...",
    "languages": {
        "xx": false,
        "en": false,
        "fr": true,
        ...
    }
}

API ​

// CLNG + meta.json -> JSON
std::string json = TonyTools::Language::CLNG::Convert(
    Language::Version version,  // game version
    std::vector<char> data,     // raw CLNG data
    std::string metaJson,       // .meta.json string
    std::string langMap = ""    // optional custom langmap
);

// JSON -> CLNG + meta.json
TonyTools::Language::Rebuilt rebuild =
    TonyTools::Langauge::CLNG::Rebuild(
        std::string jsonString  // HML JSON string
    );

// CLNG + meta.json -> JSON
std::string json = TonyTools::Language::CLNG::Convert(
    Language::Version version,  // game version
    std::vector<char> data,     // raw CLNG data
    std::string metaJson,       // .meta.json string
    std::string langMap = ""    // optional custom langmap
);

// JSON -> CLNG + meta.json
TonyTools::Language::Rebuilt rebuild =
    TonyTools::Langauge::CLNG::Rebuild(
        std::string jsonString  // HML JSON string
    );

DITL ​

aka DialogSoundTemplateList

This format defines the soundtag to the corresponding Wwise Event (WWEV) by its hash/path. The soundtag names (keys of the soundtags object) are CRC32 hashed in the file. As the names of the soundtag are in the actual event file, we know all of them. In the unlikely event that one is unknown by the internal hash list in the library, they will be output as the hexadecimal representation of the CRC32 hash found in the file.

JSON Representation ​

Schema

{
    "hash": "...",
    "soundtags": {
        "In-world_AI_Important": "...",
        "In-world_AI_Normal": "...",
        ...
    }
}

{
    "hash": "...",
    "soundtags": {
        "In-world_AI_Important": "...",
        "In-world_AI_Normal": "...",
        ...
    }
}

API ​

// DITL + meta.json -> JSON
std::string json = TonyTools::Language::DITL::Convert(
    std::vector<char> data,     // raw CLNG data
    std::string metaJson        // .meta.json string
);

// JSON -> DITL + meta.json
TonyTools::Language::Rebuilt rebuild =
    TonyTools::Langauge::DITL::Rebuild(
        std::string jsonString  // HML JSON string
    );

// DITL + meta.json -> JSON
std::string json = TonyTools::Language::DITL::Convert(
    std::vector<char> data,     // raw CLNG data
    std::string metaJson        // .meta.json string
);

// JSON -> DITL + meta.json
TonyTools::Language::Rebuilt rebuild =
    TonyTools::Langauge::DITL::Rebuild(
        std::string jsonString  // HML JSON string
    );

DLGE ​

aka DialogEvent

Now, this format is complex, and that's putting it lightly. This is the longest section for a reason, so strap in, and make sure you know your definitions.

This format, in its simplest terms, defines dialogue. These could include subtitles (optional), Wavs (WWES/M), and FaceFX animations (FXAS).

Going more in-depth, this format comprises different containers. The 4 container types are: WavFile, Random, Switch, and Sequence.

An overview of them can be found in the table below, we go more in-depth in the following section.

Figure 3: Table of DLGE containers and a brief description of them

A basic diagram (showcasing all containers) can be seen below.

Figure 4: Tree diagram showing how DLGE containers are connected together (read from left to right)

Containers ​

This section will go into more depth regarding the containers including their individual JSON representations before going onto the main format representation.

WavFile ​

The simplest container, no fancy logic behind this one.

As said in the table above, they are the "leaf" of the DLGE tree. Unless a container is empty (which is allowed), this is what all containers boil down to.

They are very simple containers and can mostly be explained through the JSON representation seen below. All fields are required unless otherwise specified.

{
    "type": "WavFile",        // important, cannot differ from this
    "wavName": "...",         // CRC32 of the "wav name", retrieved from the
                              //    path, otherwise it is the hash in hex
    "cases": [...],           // array of switch cases, see the Switch section
    "weight": ...,            // a decimal (or hexadecimal string) random weight
                              //    see the Random section
    "soundtag": "...",        // soundtag name (or hash in hex)
    "defaultWav": "...",      // the path of the "default" wav (usually english)
    "defaultFfx": "...",      // like defaultWav, but for the FaceFX animation
    "languages": {            // this can be empty or be missing languages
                              //   (i.e. xx)
        "en": "...",          // subtitle for this language
        ...
        "jp": {               // this is optional, IOI use this in H2016
            "wav": "...",     // required, the path of the wav for thislanguage
            "ffx": "...",     // required, the path of the FaceFX animation for
                              //   this language
            "subtitle": "..." // optional, subtitle for this language
        }
    }
}

{
    "type": "WavFile",        // important, cannot differ from this
    "wavName": "...",         // CRC32 of the "wav name", retrieved from the
                              //    path, otherwise it is the hash in hex
    "cases": [...],           // array of switch cases, see the Switch section
    "weight": ...,            // a decimal (or hexadecimal string) random weight
                              //    see the Random section
    "soundtag": "...",        // soundtag name (or hash in hex)
    "defaultWav": "...",      // the path of the "default" wav (usually english)
    "defaultFfx": "...",      // like defaultWav, but for the FaceFX animation
    "languages": {            // this can be empty or be missing languages
                              //   (i.e. xx)
        "en": "...",          // subtitle for this language
        ...
        "jp": {               // this is optional, IOI use this in H2016
            "wav": "...",     // required, the path of the wav for thislanguage
            "ffx": "...",     // required, the path of the FaceFX animation for
                              //   this language
            "subtitle": "..." // optional, subtitle for this language
        }
    }
}

Random ​

Not actually that Random.

The second-simplest container, they only ever contain WavFiles with the added weight property as shown above and one is picked, at random, with respect to this weight.

The only extra thing you really need to know about how weighting works in relation to randomness. If a WavFile has a higher weight, it means that it is more likely to be chosen when the Random container is invoked. These weight values should only ever add up to 1, the library currently does not check this for you.

HMLanguages gives you two options for representation of the weight value:

1. Decimal, this means it is a number between 0 and 1 (inclusive).
2. Hexadecimal string, a hex number between 000000 and FFFFFF (inclusive).

The default is decimal, and during convert, a bool needs to be set. When rebuilding, the tool can easily distinguish the two, so the bool is not required.

To convert between these two representations, you can just divide the hex weight value by FFFFFF this obviously implies that 000000 is 0, and FFFFFF is 1.

Converting weights as hex allows for more precision, but decimal is easier for most people to read. For example, for something that will occur with a 1 in 4 chance, 0.24999995529651375 (3FFFFF) will be output instead of 0.25 as it doesn't perfectly divide since FFFFFF is an odd number.

This container's JSON representation can be seen below with both decimal and hexadecimal weights.

{
    "type": "Random",
    "cases": [...],             // this only occurs when it is
                                //   a child of a Switch container
    "containers": [
        {
            "type": "WavFile",
            ...
            "weight": 0.25,
            ...
        },
        {
            "type": "WavFile",
            ...
            "weight": "3FFFFF", // this is a 1 in 4 chance
            ...
        }
        {
            "type": "WavFile",
            ...
            "weight": 0.5,
            ...
        }
    ]
}

{
    "type": "Random",
    "cases": [...],             // this only occurs when it is
                                //   a child of a Switch container
    "containers": [
        {
            "type": "WavFile",
            ...
            "weight": 0.25,
            ...
        },
        {
            "type": "WavFile",
            ...
            "weight": "3FFFFF", // this is a 1 in 4 chance
            ...
        }
        {
            "type": "WavFile",
            ...
            "weight": 0.5,
            ...
        }
    ]
}

Switch ​

No, you can't turn it off and on again.

Switch containers, as previously mentioned, work like switch cases from many programming languages with a slight difference.

First, Hitman uses a "switch key" to reference switches, the game will also pass a "case value" to this.

There are a few standard ones for these built into the engine itself, but we can also create our own. An exhaustive list (of the switch keys at least) can be seen below of the switches used in the game (as of June 2023):

It is possible to add custom switch keys and groups to the game via use of WSWB (aka DSWB) and WSWT. The WSWT file is empty, and used when invoking them from an entity. The WSWB contains all the switch cases and the key itself. These are mostly used when the game needs to change what is said depending on other variables i.e. tells, looks, location, etc.

You can create these manually using ResourceTool or using G2WwiseDataTool when integrated into a Wwise project.

Switch containers also contain a default property, which points to one of the cases (it sometimes doesn't even exist in any of the cases, we call that an "IOI moment"), normally this is a fallback line and will be used if a Switch container gets passed a case it does not have explicit handling for.

This container's JSON representation can be seen below:

{
    "type": "Switch",
    "switchKey": "AI_Sentry_ItemRequest",
    "default": "INVITE",
    "containers": [
        {
            "type": "Random",
            "cases": [
                "INVITE"        // although this is an array, it's perfectly
                                //   fine (and normal) to just have one
            ],
            ...
        },
        {
            "type": "WavFile",
            "cases": [
                "TICKET",       // but you can have more than one
                "VIPTICKET"
            ],
            ...
        }
    ]
}

{
    "type": "Switch",
    "switchKey": "AI_Sentry_ItemRequest",
    "default": "INVITE",
    "containers": [
        {
            "type": "Random",
            "cases": [
                "INVITE"        // although this is an array, it's perfectly
                                //   fine (and normal) to just have one
            ],
            ...
        },
        {
            "type": "WavFile",
            "cases": [
                "TICKET",       // but you can have more than one
                "VIPTICKET"
            ],
            ...
        }
    ]
}

Sequence ​

Don't tell me what to do!

Sequence containers are the one container that can house all other containers.

They're actually quite simple. Whatever order the containers are in, is the order that they will be played out.

If used, these will always be the root container.

You can see the JSON representation below:

{
    "type": "Sequence",
    "containers": [
        {
            "type": "Random",
            ...
        },
        {
            "type": "Switch",
            ...
        },
        {
            "type": "WavFile",
            ...
        }
    ]
}

{
    "type": "Sequence",
    "containers": [
        {
            "type": "Random",
            ...
        },
        {
            "type": "Switch",
            ...
        },
        {
            "type": "WavFile",
            ...
        }
    ]
}

And that's that! You now know about all the individual containers in the DLGE format. Now onto the main format representation and then the API!

JSON Representation ​

This will be heavily simplified as we go into more depth in the previous sections.

This layout is meant to mimic the one you saw right at the start of this section with the tree.

And we're all done, take a breather, go get a drink, and revel in the fact that you know all about a specific file type from a niche game!

LOCR ​

aka LocalizedTextResource

The classic (and possibly the most popular) localization format from the World of Assassination trilogy.

This format defines a LINE hash to a string per language. Currently, there is no hash list for these (one is planned for far in the future), so they are all output as CRC32 hashes in hexadecimal. A language map is required for convert as per the table whether that be from the version or user supplied.

The JSON format allows for users to put the plain-text version e.g. UI_LOCATION_PARIS_COUNTRY instead of the hash, these will be hashed upon rebuilding.

Glossary ​

• Hash/path - These terms will be used synonymously, they mean the (truncated) MD5 hash of files, or their full path (if known).
• Soundtag - Used in DLGE, defined in DITL. The way a piece of dialogue will be played i.e. in-world, handler, etc.
• Wwise - Refers to Audiokinetic Wwise, the audio middleware used in the Hitman WoA trilogy.
  • Event - Refers to Wwise Events, read more on them here. Soundtags specifically use "Dynamic Dialogue" events. You can use this tool to create them for the game.
  • Wavs/Wems - These terms will also be used synonymously. The game uses the wems for WWEM and WWES (functionally the same file type, that being a wem. WWES is used in H3 for dialogue). Wems are generated from wavs using Wwise.
  • WSWT - Wwise Audio Switch Template, empty file used for the template reference of switch cases.
  • WSWB/DSWB - Wwise Audio Switch Blueprint, used for referencing switch cases as events inside entities and contains the actual switch data, explained in more depth in the Switch section of DLGE.
• LINE - A file that contains a CRC32 hash of a text string e.g. UI_LOCATION_PARIS_COUNTRY. LINE files themselves are used for referencing localised lines in bricks, they are not required if it's, for example, being used in UI.
