Command Line

Quick examples:

  # compile and run immediately (if no errors)
cobra myprog.cobra

  # get help
cobra -h

  # compile only
cobra -c myprog.cobra

  # with debug
cobra -d -c myprog.cobra

  # multiple source files
cobra -c foo.cobra bar.cobra

  # passing arguments
cobra foo.cobra bar.cobra -- arg1 arg2

  # disable all checks, contracts, asserts, etc.
  # maximum performance
cobra -turbo foo.cobra

Getting help:

cobra -h
cobra -help

will dump a page detailing all the command line options supported.

The compiler runs for each invocation in a particular mode of operation. These correspond to the 'commands on paths'

• -compile or -c - compile the provided files and bind into an executable
• -run-exe or -r - as for -compile but run the executable after successful compilation. This is the default mode if none other is given
• -test - as for -compile but run the executables test cases after successful execution
• -document - parse the provided files and generate documentation from the parse tree

In addition there are three standalone commands

• -help or -h - display the cobra commandline options and descriptions
• -about - display info about cobra
• -version - display the cobra executables version information

Commandline items that are not options ( begin with '-') are taken to be filenames. Cobra can take one or a list of commandline given files to compile and the files can be cobra code ( filename ends in '.cobra') or C# code ( filename ends in '.cs'). Filenames without any extension are assumed to be a cobra code file of the same name with a '.cobra' extension

i.e

cobra myProg.cobra 
cobra myProg

both do the same thing - compile a cobra code file myProg.cobra to an executable and run it (if compilation succeeds)
