pacvis

Visualize pacman local database using Vis.js, inspired by pacgraph.

See my blog post for details: https://farseerfc.me/en/pacvis.html

以及中文介紹: https://farseerfc.me/pacvis.html

See a live demo at https://pacvis.farseerfc.me/ showing database of my arch server.

How to use

Install from AUR using any aurhelper (eg yaourt):

yaourt -S pacvis-git

Then

pacvis

Then go to http://localhost:8888/ .

You may need to zoom-in initially to see the rendered picture. Currently, we have scalability issue when there are too many packages, so we need a max level to limit the level of dependency depth. We fixed the scalability issue with a modified vis.js, but when there are more than 2000 packages the layout algorithm is still slow (more than 5 mins).

Running from source repo

git clone https://github.com/farseerfc/pacvis.git
cd pacvis

python -m venv .venv
source .venv/bin/activate

pip install .
pacvis

To be improved ...

• performance for layout algorithm can be improved
• we resolve dependency to package name using pyalpm directly now, and this information is lost on the graph
• we do not track optdepends now we draw optdepends on the graph but not consider them during topology_sort
• we need to estimate removable size (by pacman -Rcs) done
• more information from pacman can be integrated
• search by package name
• show only part of the packages (like pactree) instead of filtering by levels
• be visually attractive! applied getmdl theme
• be compatible with older browsers (Safari, IE)
• make a python setup.py install or PKGBUILD Now on aur
