An OS X system monitor in Swift, inspired by top & htop. Displays live readings of system CPU & memory usage, machine temperature sensors, fan speeds, battery information and other miscellaneous system statistics. The ncurses based TUI (text-based user interface) uses color coating to imply status and is fully resizable. Stats are updated at one second intervals while still maintaining low overhead (the observer effect is inescapable in this case sadly).
- Exploration of Swift. In particular, systems programming and interfacing with low-level C APIs
- Improved top
- Improved htop (for OS X). htop was originally written for Linux. It was forked at some point and ported over to OS X. However, the port is now using what is a 5 year old fork. Work is being done to address this
Of course, the last two are far from being true! :) dshb is still early in development.
- Xcode 7.2
- OS X 10.9+
- This is due to Swift
Make sure to use the recursive option on clone to auto init all submodules.
git clone --recursive https://github.com/beltex/dshbIncase you have already cloned the repository, run the following inside the project directory.
git submodule update --initThis will build dshb from source and place the binary and manual page in your path.
make install- ncurses
- For drawing to the terminal (tested with version 5.4 - default on OS X)
- SystemKit
- For almost all statistics
- SMCKit
- For temperature & fan statistics
- CommandLine
- For the CLI
- ronn
- For generating the manual page
All Git submodules are built part of the project as simply source files, not
frameworks (which are essentially dynamic libraries). This is because currently,
the Swift runtime dynamic libraries must be packaged with the application in
question. In the case of dshb, a single binary is generated which has the
runtime statically linked. Thus, frameworks, which expect to find the libraries
inside the application bundle (.app), cannot "see" them.

Working on this always brought a smile to my face. I hope it brings a smile to yours too. Enjoy :)
