Biscuit language compiler is a standalone terminal application called blc. It can be compiled from source code found on GitHub repository or downloaded from the home page as a binary executable (since the compiler is still under development, the binary versions may be outdated, currently compilation from the source code is preferred). All three major operating systems (Windows, macOS and Linux) are supported, but current active development is done on Windows and it usually takes some time to port the latest changes to the other platforms. The compiler executable can be found in bin directory it's usually a good idea to add the executable location to the system PATH to be accessible from other locations.
There are several options that can be passed to the compiler.
blc --help Usage: blc [options] [source-files] Alternative usage: blc [options] <-build> [build-arguments] blc [options] <-run> <source-file> [arguments] [forwarded-arguments] Options: -build Invoke project build pipeline. All following arguments are forwarded into the build script and ignored by compiler itself. Use as '-build [arguments]'. -doc Generate documentation and exit. -opt=<debug|release-fast|release-small|release-with-debug-info> Specify binary optimization mode (use 'debug' by default). -release Specify binary optimization mode to release. (same as '-opt=release-fast') -run Execute BL program using interpreter and exit. The compiler expects <source-file> after '-run' flag, the file name and all following command line arguments are passed into the executed program and ignored by compiler itself. Use as '-run <source-file> [arguments]'. -shared Compile shared library. -silent-run Execute BL program using interpreter and exit. The compiler expects <source-file> after '-silent-run' flag, the file name and all following command line arguments are passed into the executed program and ignored by compiler itself. Use as '-silent-run <source-file> [arguments]'. This flag also suppress all compiler console outputs. Basically it combines '-run' and '--silent' into a single flag. This can be useful in case the compiler is called implicitly from UNIX shebang. --about Print compiler info and exit --assert=<default|on|off> Set assert mode ('default' option sets assert 'on' in debug and 'off' in release mode). --ast-dump Print AST. --configure Generate configuration file and exit. --di=<dwarf|codeview> Set debug info format. --doc-out-dir=<STRING> Set documentation output directory. (Use 'out' in current working directory by default.) --emit-asm Write assembly to file. --emit-llvm Write LLVM-IR to file. --emit-mir Write MIR to file. --error-limit=<N> Set maximum reported error count. --full-path Report full file paths. --help Print usage information and exit. --lex-dump Print tokens. --no-analyze Disable analyze pass, only parse and exit. --no-api Don't load internal API. --no-bin Don't write binary to disk. --no-color Disable colored output. --no-jobs Enable single-thread mode. --no-llvm Disable LLVM back-end. --no-usage-check Disable checking of unused symbols. --no-warning Ignore all warnings. --reg-split=<off|on> Enable/disable splitting of structures passed into the function by value into registers. --run-tests Execute all unit tests in compile time. --silent Disable compiler console logging. --stats Print compilation statistics. --syntax-only Check syntax and exit. --target-experimental Enable experimental compilation targets. --target-host Print current host target triple and exit. --target-supported Print all supported targets and exit. (Cross compilation is not allowed yet!) --tests-minimal-output Reduce compile-time tests (--run-tests) output (remove results section). --verbose Enable verbose mode. --verify-llvm Verify LLVM IR after generation. --version Print compiler version and exit. --vmdbg-attach Attach compile-time execution debugger. --vmdbg-break-on=<N> Attach compile-time execution debugger and sets break point to the MIR instruction with <N> id. --where-is-api Print path to API folder and exit. --work-dir=<STRING> Set current working directory. Compiler use by default the current working directory to output all files.
blc --config to change compiler configuration; this command generates a new
etc/bl.yaml configuration file containing all the needed information about your system. This configuration runs automatically in case the config file was not found.
- After a regular compilation process
blcreturn 0 on success or a numeric maximum error code on the fail.
-runflag is specified
blcreturn status returned by executed
mainfunction on success or numeric maximum error code on fail (compilation error or compile time execution error).
--run-testsflag is specified
blcreturns a count of failed tests on success or a numeric maximum error code on a fail.
