12 Slate is a prototype-based, multi-dispatch object-oriented language that
13 runs from a highly-customizable live environment. The implementation is
14 highly portable and relatively lightweight.

22 Bug reports and requests for information can be made via the Slate mailing
23 list, described at: http://groups.google.com/group/slate-language

34 To get a slate repository on your computer to play with, run:
35 git clone git://repo.or.cz/cslatevm.git
41 'make slate.image' builds a standard saved image from a kernel image.
42 'make edit' launches the VM and standard image in Emacs with a scratch area.
43 '(sudo) make install' installs the VM and images in global directories (/usr/local/ by default) so that the VM can be invoked as just "slate".
44 'make plugins' builds the plugins that you need for the GUI and FFI-related stuff.
46 Read common.mk for more options.
53 This starts slate using <image>.
55 Run 'slate -h' for more details.

68 If you make changes to core slate files (like adding a new field to
69 CompiledMethods), sometimes the only easy way to implement those changes
70 throughout the system is to rebuild Slate completely. Here is how you
71 generate a new kernel image:
75 make bootstrap WORD_SIZE=64 && make slate.image WORD_SIZE=64
77 make bootstrap WORD_SIZE=32 && make slate.image WORD_SIZE=32
81 At the Slate REPL, execute:
82 load: 'src/mobius/init.slate'.
84 Image bootstrap &littleEndian: True &bitSize: 32.
86 Image bootstrap &littleEndian: True &bitSize: 64.
88 Then you will load the resulting kernel image like a regular image:
90 ./slate -i kernel.new.<endian>.<wordsize>.<timestamp>.image
92 After the image is loaded, you will want to save it so you
93 don't have to go through loading the kernel again:
95 Image saveNamed: 'slate.image'.
101 make vmclean && make DEBUG=1
106 f <n> (change frame to one with an 'oh' object (struct object_heap*))
108 See the slate backtrace -> print print_backtrace(oh)
109 Inspect an object -> print print_detail(oh, struct Object*)
110 See the stack -> print print_stack_types(oh, 200)
113 Build flags (e.g. make vmclean && make DEBUG=1
114 EXTRACFLAGS="-DGC_BUG_CHECK -DSLATE_DISABLE_METHOD_OPTIMIZATION
115 -DSLATE_DISABLE_PIC_LOOKUP"):
117 GC_BUG_CHECK: extra features for debugging the GC
119 SLATE_DISABLE_METHOD_OPTIMIZATION: Don't optimize methods after
120 calling them a lot. Right now it sets method->oldCode to the current
121 code. In the future it should do inlining.
123 SLATE_DISABLE_PIC_LOOKUP: At the call site in the current method there
124 is a cache of called functions which is checked after the global cache
125 when doing method dispatch.
127 SLATE_DISABLE_METHOD_CACHE: Disable the global cache when doing method
130 SLATE_USE_MMAP: Use mmap to allocate the object memory. You should be
131 able to get constant pointers between runnings so that you can debug
132 by learning memory addresses from previous runs.
134 PRINT_DEBUG and the many PRINT_DEBUG_*: Print more verbose output to
137 ALWAYS_FULL_GC: Never do a new-generation garbage collection.
139 GC_MARK_FREED_MEMORY: Mark freed memory with 0xFE in case someone
140 tries to use it again. (Slow)

144 Source directory structure
145 --------------------------
148 : The C files for the VM. Interprets bytecode and provides necessary facilities for primitives, gc, etc.
149 src/mobius -> The slate files for the compiler, lexer, bootstrap, and close-to-vm? facilities etc.
151 : The core libraries for the default slate system.
153 : The standard but optional libraries.
155 : C code for slate FFI calls. `make plugins' to build
157 : The slate UI code that probably calls plugins to draw the basics. load: 'src/ui/init.slate'.
159 : The slate GTK interface. load: 'src/ui/gtk/demo.slate'.
161 : The slate networking code. load: 'src/net/init.slate'.
166 Besides using grep, there are a few facilities:
168 #as: implementations do: [|:each| each definitionLocation ifNotNilDo: [|:l| inform: (l as: String) ]].
170 (#parseExpression findOn: {Syntax Parser}) definitionLocation
