League of Legends chat parser

Brief Description:
LoLCP is a parser for League of Legends chat logs.
At this stage, it focuses on extracting timestamps from text lines using a simple formal grammar implemented with pest.

At the current stage, the parser only handles timestamp recognition.

Technical Description

The goal of this project is to eventually allow users to upload a plain text chat log and receive structured JSON output that contains (based on the provided log context):

  • all players in the match,
  • which champions they played,
  • which team achieved specific objectives (like jungle monsters or towers),
  • kill statistics (who killed whom and how many times, with and without gold streaks),
  • and all chat messages grouped by player or team,

— all tied together by their corresponding timestamps.

Parsing Process

Each chat line follows a semi-structured format, for example:

Type /help for a list of commands
00:42 uskin432 (Warwick) is on the way
00:52 kozakSyla (Lux) has drawn first blood!
02:24 Enemy team has completed the Feat of Warfare!
13:05 Golf4f (Mel) has shut down BorysBulba (Tahm Kench)! (Bonus Bounty: 149G)
13:08 [Party] piwkobb (Yone): Cho'Gath Heartsteel - 20 charges
13:10 BorysBulba (Tahm Kench) purchased Control Ward
14:46 kozakSyla (Lux) is on rampage!
15:40 piwkobb (Yone) has targeted TheMiozl - (Renekton)
16:53 [All] piwkobb (Yone): hello this is all chat msg
17:34 [Team] kozakSyla (Lux): hi in team chat
18:32 kozakSyla (Lux) has targeted the Power Flower (33%)

We focus on detecting the time mark at the beginning of the line.

Grammar Rule

Defined using the pest parser generator:

time = { ASCII_DIGIT ~ ASCII_DIGIT ~ ":" ~ ASCII_DIGIT ~ ASCII_DIGIT }

Example valid timestamps:

00:42
02:24
18:32
