EXAMPLES:


1. "hello world" intro/hello_world.c
 Just enough C code to setup a from-scratch metadesk program, parse
 "hello world", and print the results.

 This example is a "build test", to make sure your compiler is finiding the
 source files and can build them.


2. "parse check" intro/parse_check.c
 An example utility that parses files specified on the command line, reports
 any errors from the metadesk parser, and then prints the results.

 This example includes lots of notes about the basics of setting up a metadesk
 parsing program from scratch, and getting used to the helpers in the library.


3. intro/hello_world.mdesk, intro/labels.mdes, intro/sets.mdesk
 These files include examples of the features of the metadesk language. We
 recommend putting these through the "parse check" example utility to see how
 different language constructs get parsed, if you want to get more familiar
 with the language side of metadesk.


4. "data desk like template" intro/data_desk_like_template.c
 An example for users of Data Desk, the pre-cursor to Metadesk.


5. "user errors" user_errors/*
 This example shows how you can mix in your own error reporting with the errors
 that come back from the metadesk parser.


6. "type metadata" type_metadata/*
 (Start exploring this example at type_metadata/type_metadata.c)

 A common use case for a metaprogramming system in C is to mark up type
 information with metadata. This example shows the "Metadesk way" of
 implementing that use case. This is the biggest example included and closely
 matches what a typical metadesk based metaprogram grows to look like over
 time. It includes:
  analyzing a metadesk parse tree
  doing error checks
  generating C types, functions, a data tables
  generating type serialization metadata
  generating enum string tables
  generating enum mapping functions
  printing diagnostics
  including generated files into a final program
 
 Commentary in this example focuses on strategies for setting up an effective
 metaprogram.


7. "overrides" integration/overrides.c
 When including the Metadesk library into an existing codebase, the overrides
 system in the library will let you plug in existing implementations you have
 for many of the basic requirements of the library. This can also be useful if
 you want to make your program CRT-free, or direct metadesk allocations to your
 own custom allocator.
