nwn-lib-d

Multi-platform D library & tooling for handling Neverwinter Nights 1 & 2 resource files

---

Features

Command-line tools

nwn-lib-d tools are a set of command-line tools for manipulating Neverwinter Nights 2 files (and some NWN1 files). They are multi-platform (usable on Windows or GNU/Linux) and do not require the game to be installed.

Download nwn-lib-d tools

• nwn-gff

  • Read / write GFF files (ifo, are, bic, uti, ...)

    Format	Parsing	Serialization	Comment
    gff	✅	✅	NWN binary. Generated binary file match exactly official NWN2 files (needs to be tested with NWN1)
    json	✅	✅	Json
    json_minified	✅	✅	Same as json but minified
    json_legacy	✅	✅	Json, compatible with Niv nwn-lib
    pretty	❌	✅	Human-readable

  • Pros

    • Pretty fast
    • GFF nodes keeps their original ordering, making diffs very consistent
    • Automated GFF modifications (set / add / remove nodes)

• nwn-tlk

  • Serialize TLK files to readable text.

    Format	Parsing	Serialization	Comment
    tlk	✅	✅	NWN TLK binary format
    text	❌	✅	Human-readable

• nwn-2da

  • Check 2DA format
  • Re-format / fix issues
  • Merge rows into an existing 2DA

• nwn-erf

  • Create, extract or view ERF files (hak, erf, mod, pwc) in a reproducible manner (same content => same checksum).
  • Pros
    • By default sets the ERF buildDate field to a 0 value, to create reproducible erf files.
    • Memory efficient (files are streamed, not copied into memory)

• nwn-trn

  • TRN/TRX experimental tool:
    • trrn-export: Export the terrain mesh, textures and grass
    • trrn-import: Import a terrain mesh, textures and grass into an existing TRN/TRX file
    • watr-import: Export water mesh
    • watr-import: Import a water mesh into an existing TRN/TRX file
    • aswm-strip: Reduce walkmesh data size by removing non-walkable triangle & related data. Can reduce LZMA-compressed files to 50% of their non-stripped size (depending on the amount of unused triangles of course).
    • aswm-export-fancy: Export custom walkmesh data into a colored wavefront obj
    • aswm-export: Export walkable walkmesh into a wavefront obj
    • aswm-import: Import a wavefront obj as the walkmesh of an existing TRX file
    • bake: Bake an area (prototype, placeables and walkmesh cutters are not supported)

• nwn-srv

  • Interact with NWN2 server:
    • Measure latency (ping)
    • Query server info and status

• nwn-bdb

  • View/search Bioware/foxpro database content (dbf + ctx + fpt) using regular expressions.

Tips & tricks

Generate git diff from GFF & TLK files

1. Configure Git to use the tools

• Using git command line:

git config --global diff.gff.textconv "$PATH_TO_NWNLIBD_TOOLS/nwn-gff -i \$1"
git config --global diff.tlk.textconv "$PATH_TO_NWNLIBD_TOOLS/nwn-tlk -i \$1"

• Or by editing .gitconfig:

[diff "gff"]
  textconv = 'C:\\Program Files\\nwn-lib-d\\nwn-gff' -i $1
[diff "tlk"]
  textconv = 'C:\\Program Files\\nwn-lib-d\\nwn-tlk' -i $1

2. Configure your git repository to use GFF / TLK diff by creating .gitattributes file:

#Areas
*.[aA][rR][eE] diff=gff
*.[gG][iI][cC] diff=gff
*.[gG][iI][tT] diff=gff

#Dialogs
*.[dD][lL][gG] diff=gff

#Module
*.[fF][aA][cC] diff=gff
*.[iI][fF][oO] diff=gff
*.[jJ][rR][lL] diff=gff

#Blueprints
*.[uU][lL][tT] diff=gff
*.[uU][pP][eE] diff=gff
*.[uU][tT][cC] diff=gff
*.[uU][tT][dD] diff=gff
*.[uU][tT][eE] diff=gff
*.[uU][tT][iI] diff=gff
*.[uU][tT][mM] diff=gff
*.[uU][tT][pP] diff=gff
*.[uU][tT][rR] diff=gff
*.[uU][tT][tT] diff=gff
*.[uU][tT][wW] diff=gff

#Others
*.[pP][fF][bB] diff=gff
*.[tT][lL][kK] diff=tlk
