What is Battlestar?
- A work in progress.
- Created for fun and for the educational process.
- A programming language specifically for 64-bit and 32-bit x86 and Linux.
- Subset of assembly with an alternative syntax and with support for inline C.
- The indended purpose is for writing 4k and 64k demoscene demos.
Build and install Battlestar, build the samples and run the "life" sample:
make; sudo make devinstall; make samples; cd life; ./life.sh
This requires DosBox, Go, Yasm and GCC.
gcc-go is not supported yet.
Features and limitations
- The resulting executables are tiny!
- "hello world" is only 174 bytes for 32-bit Linux (when using sstrip from elfkickers). (238 bytes for 64-bit Linux, 31 bytes for 16-bit DOS)
- It's possible to write an operating system / kernel with only one source file.
- Full support for inline C (by utilizing gcc).
- C and Battlestar code can exist in the same source file and calls can be made both ways.
- Battlestar programs compiles almost instantly.
- Programs can be run like scripts by including this line at the top:
- Interrupts can be called with the same syntax for both 32-bit and 64-bit x86 on Linux.
- Also supports 16-bit x86 with DosBox.
- The intermediate assembly is fully commented.
- No register allocator, just an alternative assembly syntax.
- macOS support
- Reimplementing 16-bit demoscene demos without using any inline assembly
- See TODO
Make sure Go, Yasm and GCC are installed.
Install on Linux:
sudo make install-linux
Install on macOS:
sudo make install-macos
For development, install soft links instead:
sudo make devinstall
Build all the samples:
- go >= 1.3
Optional runtime dependencies
- gcc (for inline C support)
- elftools/sstrip (for even smaller binaries)
- binutils (for disassembling with objdump)
- dosbox (for running 16-bit executables) (only GCC 4.9 and up supports compiling to 16-bit with -m16)
- SDL 2 (must be compiled and installed manually if on Red Hat 6)
- tcc (for even smaller binaries, in many cases)
