# TACT Parser
Parser for various [TACT file formats][tact-ff], as they are used on the NGDP
CDN.
Some other community tooling describes these as ["CASC files"][casc]; but CASC
refers to the virtual filesystem used by locally-installed copies of games.
## Roadmap
The plan is to read enough of the the TACT files to allow [`ngdp-client`][] and
[`tact-client`][] to download and extract WoW data files from the NGDP CDN.
This is not yet integrated with the rest of `cascette`, and has been tested
using existing cached copies of CDN data from
[SimulationCraft's `casc_extract.py`][simc].
- [x] Read [WoW Root][wow-root], to find the file ID and MD5s of each variant
of game data files (eg: `.db2`)
- [ ] Read [encoding table][encoding], to find the BLTE file keys for a game
data file MD5
- [ ] Read [BLTE files][blte], to get file content
- [ ] Read [patch files][patch]
