Simple Rust / GTK tool to clean up clipboard text.

• Shows current clipboard targets.
• Supports several text encodings (UTF-8, UTF-16 with BOM, ISO-8859-1, ...)
• Includes "Wipe clipboard" function that overwrites the current clipboard content with an empty string. Does not really clear the clipboard as this often does not work due to clipboard managers (e.g. klipper overwrites the clipboard with the last content if it is cleared).
• Configurable via YAML/JSON/TOML config file
  • Supports defining transformation profiles in order to define which characters should be mapped to which output strings.
  • Characters can be mapped to string literals, HTML/XML entities, \x## hex bytes, \u#### and \U######## (u/U depending on codepoint value), U+# and \u{#}. See src/assets/default-config.yaml for examples.

The configuration file is called clipboard-builder.ext (ext being one of yaml, json or toml) and can be set at multiple locations:

• on Linux, Mac OS, Solaris, Free BSD and OpenBSD:
  • /etc/clipboard_cleaner
  • /etc/clipboard-cleaner
• On all operating systems:
  • Subdirectories conf and etc of the processes current working directory
  • In the operating-system specific application config directory. Clipboard cleaner uses the directories crate with qualifier net.laerrus, company Laerrus Ultd. and application name clipboard-cleaner. In a typical Linux system with XDG support, the config file would be in the directory ~/.config/clipboard-cleaner.

Just start the executable. There are no commandline-arguments. You can exit the application easily via pressing ESC. No other keyboard shortcuts are supported yet.

The project was developed with Rust version 1.60.0, but will probably work with other versions too. To build the project, either use cargo build or cargo build --release. There are custom release settings configured in Cargo.toml to reduce the executable size (currently to less than 1MB on x86_64) since this project is supposed to be repeatedly started by a keyboard shortcut.
