A fast and minimalistic image viewer

About

Refer to the website for an overview.

Emulsion is targeting Windows, Mac, and Linux although it is currently only being tested on Linux and Windows.

To build the software, obtain the latest stable release of Rust and after navigating to the source directory simply run the command cargo build --release using your preferred command line interface.

Contribution is welcome. Feel free to post feature requests, bug reports, and make pull requests.

Custom configuration

The cfg.toml file allows for some modifications in the behavour of emulsion.

Depending on the platform this file can be found or created at the following location.

• Windows: %appdata%\emulsion\config\cfg.toml
• MacOS: $HOME/Library/Preferences/emulsion/cfg.toml
• Linux: $XDG_CONFIG_HOME/emulsion/cfg.toml or $HOME/.config/emulsion/cfg.toml

The contenst of the cfg.toml file may for example be the following:

[bindings]
img_next = ["k"]
img_prev = ["j"]

[updates]
check_updates = true   # set to false to disable checking for updates

Currently the only valid sections are: [bindings] and [updates]. All sections in this file are optional, meaning that if for example only [updates] is specified then the default key-bindings will be used.

The [updates] section can contain only one field, namely check_updates which may be set to either true or false. Emulsion fetches the latest version number and provides a notification only if check_updates is set to true. The default value is true. (Note that this field has no effect when emulsion is compiled without networking.)

This file may contain a [bindings] section which allows defining custom key-bindings. For more on that please refer to the Bindings.md file.

Notes on Networking

When installing Emulsion through a perpared package like the Windows installer, Emulsion will have networking enabled and by default will check for updates. However the default feature-set for emulsion does not include networking. This means that Emulsion will not have networking dependent capabilities when invoking

cargo install emulsion

To enable such features with this method, run

cargo install emulsion --features=networking

Reporting bugs

If Emulsion closed unexpectedly please locate the "panic.txt" file. This file has a different location depending on the target platform.

• Windows: %localappdata%\emulsion\data
• MacOS: $HOME/Library/Application Support/emulsion
• Linux: $XDG_DATA_HOME/emulsion or $HOME/.local/share/emulsion

When posting a bug report please upload the contents of this file to GitHub. If you deem it too large just paste the last panic entry between the rows of equal signs. If there's no "panic.txt" file, describe the scenario in which you experienced the faulty behaviour, and steps to reproduce it if you believe that could help.
