CLI tool and libraries for working with the various file format that ToS uses, currently supports ies and ipf files, with some mappings done for the xac model format.

This tool has not been tested with the live version of the game, and is not intended to be used with it, therefore no support will be provided for it.

Note that support for this tool is not provided by IMC Games, and is not officially supported by them.

Requires Java 17 or newer to run.

If unsure of where to easily download Java 17, you can use the Microsoft build of OpenJDK 17, which can be downloaded here.

Download the latest version from releases and extract it to a safe location, add the bin directory to your PATH (or the Linux equivalent), and you can then invoke the CLI environment by invoking tos in your preferred terminal.

All commands have basic -h / --help support, which will print out the usage of the command and the available options. For example tos ies unpack -h will print out all available arguments/options for unpacking an ies file.

The ies and ipf commands are written to be sufficiently smart, and will try to prompt the user for input if the given file structure is somehow wrong, but they are not fool-proof, so errors can and will happen.

Note that all commands have more options than what's shown below, the arguments shown below are just what you need to know to quickly get started. For all arguments, like explained above, use the -h / --help option on the command.

Handles the ies file format, which is a proprietary format used by ToS for storing game data.

IES files are essentially a binary representation of a dictionary, with the mapping string -> f32 and string -> string, these files are then used by the Lua scripts that run the client/server as pseudo class structures.

Only 3 data types are supported by the ies format:

• Number 0x0
• • A 32-bit floating point number.
• Localized String 0x1
• • A string that can be localized by the client/server, the localized variant is stored in separate files.
• Calculated String 0x2
• • A string whose content is "calculated"/static, and is not privy to the localization mechanics.

If a string values key starts with CP_ then its type is Calculated String otherwise it's a Localized String.

tos ies unpack <input> [output]

Unpacks an ies file(s) into a directory determined by the output argument. If output is not provided, the output directory will be created in the same directory as the input file, with the name unpacked_ies.

If input is a single file, only a single ies file will be unpacked, if input is a directory, then all files in the directory will be traversed, and all ies files found will be unpacked.

tos ies pack <input> [output]

Packs an ies file(s) into a directory determined by the output argument. If output is not provided, the output directory will be created in the same directory as the input file, with the name packed_ies.

If input is a single file, only a single ies file will be packed, if input is a directory, then all files in the directory will be traversed, and all xml (this actually depends on the format used, but currently only the xml format is supported) files found will be packed.

The xml format used by unpack and pack tries to mimic that of the official one, which means that a lot of the data is inferred.

Note that "optional" columns are not supported, that means that if one entry has, say column, CoolLevel, but no other entry in the same xml file has that column, the conversion will fail. To fix this, either remove CoolLevel from the entry that has it, or add CoolLevel to every entry in the xml file.

First the key and value is checked to determine an initial type, where it's resolved as follows:

• Does the key start with CP_?
  • If yes, then the type is Calculated String
  • If no, then we go to the next step
• Does value start with - or only contain the characters [' ', '.', '0'..'9']?
  • If yes, then the type is Number
  • If no, then the type is Localized String

If a value that was previously inferred to be a Number is then inferred to be a Localized String then the type is changed to Localized String. This is because the intial type is just a guess, and can be wrong.

The kind of a column is determined by the prefix of its key:

• EP_ -> EP
• CP_ -> CP
• VP_ -> VP
• CT_ -> CT
• Anything else -> NORMAL

Whether a column is an NT column is determined by if its key contains _NT.

Whether a field is a script field is determined by if its value contains SCR_ or SCP.

Handles the ipf file format, which is a proprietary format used by ToS for storing game data and assets.

IPF files are essentially just a proprietary archive format, with a custom footer, and encrypted file contents.

Both unpack and pack commands will attempt to use multiple cores by default, the amount of cores used can be changed with the -t/--threads option. By default, it's half of the available cores.

To create custom ipf files, use the pack command on the directory containing the files you want to pack. To understand the structure of the ipf file, it's recommended to first unpack an ipf file and mimic that.

tos ipf unpack <input> [output]

Unpacks an ipf file(s) into a directory determined by the output argument. If output is not provided, the output directory will be created in the same directory as the input file, with the name unpacked_ipf.

If input is a single file, only a single ipf file will be unpacked, if input is a directory, then all files in the directory will be traversed, and all ipf files found will be unpacked.

Unpacked ipf files will contain a .ipf_data file, which contains data required by the pack command to repack the ipf file properly.

tos ipf pack <input> [output]

Packs the input file/directory into an ipf file(s), the output argument determines the name of the ipf file, if input contains multiple ipf directories, then output must be a directory, otherwise it must be a file.

If no .ipf_data file is located in the input then the user will be prompted to enter the required data, and a new .ipf_data file will be created in input containing the provided data.

If the structure of the input directory is ambiguous then the user will be prompted for further information. Or in the case that the structure is not resolvable at all, an error will be printed and the program will exit.
