LoGiVi (git visualisation software)

[rmcode]

LoGiVi is a git-repository visualisation tool inspired by Gource and currently in development. It was written from scratch using Lua and the LÖVE framework.



If you find any bugs or have suggestions, please submit a ticket in the bug tracker or reply to this topic.

The code lives at github. You can grab the latest release here.

Nice, didn't find how to change the resolution though.

Thanks for the video! LoGiVi visualized in LoGiVi ... that's pretty meta

Nice, didn't find how to change the resolution though.

The resolution can be changed in the config file. More options and keyboard controls will be added in the next update.

Released version 0142

Code: Select all

# Version 0142 - 01/04/2015
### Additions
- Added more options to the logivi config file
- Added ui panel which can be moved, resized and scrolled which now contains the file list
- Added keybindings for camera controls to the config file
- Added option to hide commit authors in the config file
- Added keybinding to hide / unhide commit authors while LoGiVi is running
- Added option to set the speed at which commits are loaded in the config file
- Added option to set the width of the graph's edges in the config file
- Added option to set visibility of the file panel in the config file.
- Added keybinding to hide / unhide the file panel while LoGiVi is running
- Added labels which are drawn next to their respective node

### Fixes
- Fixed [#9](https://github.com/rm-code/logivi/issues/9) - Use radius of a node in mass calculation to make sure small nodes get pushed away far enough from bigger nodes
- Fixed [#8](https://github.com/rm-code/logivi/issues/8) - Prevent crash when trying to modify a file which doesn't exist (anymore)
- Fixed [#7](https://github.com/rm-code/logivi/issues/7) - Parents are removed correctly if they became empty after their last child had been removed
- Fixed [#6](https://github.com/rm-code/logivi/issues/6) - Avatars no longer rotate with the camera
- Fixed [#2](https://github.com/rm-code/logivi/issues/2) - Edges are removed correctly when a node is killed

### Other changes
- Updated message box when no git log is found and added a button to directly open the logivi wiki
- Improved graph layout by tweaking the mass calculation and charge of each node (edges should now be shorter which reduces the total size of the graph)
- Increased width of the graph's edges
- Replaced old movement code for authors with physical based approach (Closes [#5](https://github.com/rm-code/logivi/issues/5))

I really like it. But it would be great if the camera could auto adjust

Thanks a lot

Having an auto-adjustable camera was on my todo list from day one, but last time I tried to implement it the math was a bit too intimidating and I got sidetracked. Will see what I can do!

The way I see it I have to do the following things:

- Calculate a rectangle around my graph
- Check if one of the sides is (noticeably) longer than the other
-> If it is the graph should be turned by 90 degrees
- Check if the graph's rectangle is smaller or bigger than the screen size
-> If it is smaller we need to zoom in
-> If it is bigger we need to zoom out
