LF2 Survival Stage Generator is a work-in-progress (WIP) project for generating random survival stages fir Little Fighter 2. There is still a lot of work to be done. For ideas about the planned functionality take a look at doc/notes.org
or doc/notes.md
.
The code is written in GNU Guile (3.0.7
). As far as I know there is no GNU Guile 3.0.7 version for other operating system than GNU/Linux. This means, that in order to use this program, you will likely have to use GNU/Linux.
(project is still work-in-progress)
This repository uses git submodules.
git clone git@notabug.org:ZelphirKaltstahl/lf2-data-reader.git
cd lf2-data-reader
git submodule update --init --recursive
With GNU Guix installed, you can do the following:
activate the specified GNU Guix environment:
bash guix-env/env.sh
run the program:
make run
The output should show a decrypted stage.dat
file.
All you need is a working GNU Guile installation to run the program. How you get it, does not really matter. For example you could use your system package to install GNU Guile, if it is available in your the package sources of your system, or you could download the source code of GNU Guile and compile it for your system.
Here is an example for an interactive REPL session. Run your REPL from the root directory of this project and then input the following:
(add-to-load-path ".")
(add-to-load-path "lib")
(add-to-load-path "lib/lf2-data-reader/")
(add-to-load-path "lib/lf2-data-crypt/")
(add-to-load-path "lib/guile-random-utils/")
(load "lib/lf2-data-reader/renderer.scm")

(define survival-data (find-in-peg-tree stage-data 'SURVIVAL-STAGE))
(define phases (flatten-filter-peg-tree (find-all-in-peg-tree survival-data 'PHASE) 'PHASE))
(define phase (list-ref phases 0))
(print-limited stage-text #:max 1024)
(print-limited (fisher-yates-shuffle phases)
#:max 2048)
(render-data (list phase))
You can run unit tests using the following command:
guile -L . test/<TEST FILE>
Or run tests from submodules, if tests exist.
The project depends on nothing except GNU Guile. It is tested using GNU Guile 3.0.7
, but probably works using many older versions as well.
