9b1cd56050 Changed the identifiers/values on graph nodes in the control-flow graph to be produced monadically, and altered the tests accordingly 2007-10-27 23:59:33 +00:00

8fa046798a Tidied up and simplified the test code in FlowGraphTest to operate on lists of nodes/edges, rather than decomposing the graph 
When you decompose a graph, each edge only appears once; on one of the nodes it is attached to.  This meant our testing was not working properly.

The easier solution is to forget how the graph works underneath, get a list of nodes and a list of edges, then operate on those.

f0c552663b Added the initial implementation of a module (and tests) for generating a control-flow graph from an AST 
This implementation needs to be changed; it currently uses Meta as a primary key for nodes, but that isn't valid.

f0fdc05ff3 Added a large hunk of code in ShowCode that allows us to print out occam programs using the right indentation. 
The code is messy, and not quite finished, but for now it isn't actually being used.  So I'm committing it, ready to be fixed up at a later date.

Neil Brown
c17cf0ce38 Added the first attempt at getting Tock to do an all-in-one compile, from occam/Rain all the way through into an executable binary 2007-10-08 21:18:07 +00:00

Neil Brown
135a4d6bfd Added a helper function for marking when a test is a Rain test (which means any test output will be displayed as Rain code, not as occam code) 2007-09-19 11:08:25 +00:00
Neil Brown

c899282873 Changed dieIO to print out context for the error when it is given a valid meta tag 2007-09-18 11:48:11 +00:00

c97d1d00c8 Changed the error type from String to ErrorReport throughout the code 
ErrorReport is of type (Maybe Meta, String), thereby adding an optional code position to error messages.

Die has been changed so that die and dieP are now implemented in terms of dieReport (:: ErrorReport -> m a).  This involved changing less code than changing die to be of type ErrorReport -> m a.  All that had to be changed directly was that Die instances now implement dieReport instead of die.

Any bits of code that "caught" errors has been changed so that it handles ErrorReport instead of String.  This ErrorReport is eventually, in Main, passed to dieIO, which will soon be changed to read the file in and provide the context.  Accordingly, MonadIO m has been added as a constraint to dieIO, and dieInternal has been changed to no longer use dieIO (because really we can't add the MonadIO constraint to dieInternal).

Various error messages have been changed.  Notably, all instances of fail in ParseOccam have been changed to use die or, wherever possible, dieP.  A similar thing has been done in EvalConstants and EvalLiterals.

a78fb8e917 Add functions to pack Metas as string prefixes. 
These will be useful for passing source positions through Parsec's string error
mechanism.
