It already has automatic installer(your folder with this webui will be portable), just download repo, run setup-windows.bat and it will be done. Text generation webui is supporting alot of backends, that make it modular and not too suitable to make portable of it. If you want something really "portable", use llama.cpp. Or ima just a lazy to do it, ya(.
>could you show me the process of packaging the application?
I have a rough "toolkit" of it on huggingface (link) with also rough instructions in it. In short the process consists of:
-cloning repo from github or huggingface demo (yes you can clone and run it locally)
-pip installing all repository requirements (open miniconda3/scripts/start.bat in cmd, this will open miniconda)
-then little rewriting .bat file to run exact .py file that will be launch something you want and adding some things that repo need to be set, such as environment variables or smth. This bat file is stolen from various other .bats (basically from one that was in automatic1111 portable) and sets your path(folder where you can execute .exes just by typing its name, not needed to type its full path), user folder, appdata folder, python folder, huggingface cache folder and other folders that needs to be placed deeply in your computer as paths inside the miniconda3 folder, that makes it portable. If you open each .bat, i created rough description of what each section does.
-testing it and packing in .7z
You can theoretically make a portable of any program, that is have dependeces of some unix hell packages, like this one or this. If your program is written and compiled for windows, in 95% it just dont needs an installer lol, you can just pack your skyrim folder and here it is, portable skyrim.
