A script for analyzing tournament replay packs

Replay Parsing for Tournament Replay Packs

This is a script for parsing tournament replay packs. It recursively searches sub-directories for replay files, then parses the replays using the Zephyrus Replay Parser.

You can inject a function to analyze output data. Analyzed data is aggregated and stored, then exported as JSON.

Information from directory names such as group, BoX and player names can be also be parsed and associated with replay data.

Installation and Usage

This script is hosted on PyPI and can be installed with pip

pip install recursive_parse

The recursive_parse function is imported by default

import recursive_parse

Required Arguments

There are 2 required keyword arguments for the function: sub_dir and data_function.

sub_dir specifies the relative path of the replays you want to parse from the location of the script

dir/
  analysis.py <-- recursive_parse called here
  replays/
    ...

sub_dir = 'replays'

data_function is a function supplied by the user to analyze output data from parsed replays. Returned data is appended to a list which is exported as JSON after all replays have been parsed.

You can access all the information available from parsed replay (players, timeline, stats, metadata) as well as enclosed information in your supplied function via kwargs. This includes default values and any information parsed from directory names.

Defaults currently available are ignore_units and merge_units.

ignore_units is a list of temporary unit which are usually not wanted.

merge_units is a dictionary in the format of <unit name>: <changed name>. It can be used to merge information from different unit modes or to re-name a unit, such as LurkerMP --> Lurker.

Optional Arguments

recursive_parse takes 2 optional keyword arguments: player_match and identifiers. Both are RegEx patterns that parse information from directory names.

player_match is specifically for parsing player names from directories. It takes a list of tuples of RegEx patterns and the type of search to perform.

Ex: (<pattern>, <search type>)

You can choose between search or split for search type, but the last pattern must be a split to separate the player names.

The default patterns are:

standard_player_match = [
    ('\\w+ +[v,V][s,S]\\.? +\\w+', 'search'),
    ('.vs\\.?.', 'split'),
]

identifiers is for parsing information from directory names. It contains a list of tuples of RegEx patterns and the chosen name of the pattern. It has no default patterns.

Ex: (<pattern name>, <pattern>)

The list of tuples can be accessed through kwargs['identifier'] in your data_function.

Example

The hsc_analysis.py file is an example of usage for replay files from HSC XX.

The parse_data function loops through each player's units and buildings that were created during the game and records information about the unit/building and game. It also indentifies and stores groups that players were in.

Exporting Data

Data is exported as JSON to a JSON file by default, but you can use the json_to_csv.py file to create a CSV file from the JSON data.

In future there will be an option to define a data schema as an argument for recursive_parse.
