[Don't just crash if the command is invalid...
eb@cs.st-andrews.ac.uk**20090309125424]
[Added global options
eb@cs.st-andrews.ac.uk**20090309124541
:o sets, :o f- or :o f+ to turn forcing/collapsing off/on
:o r- or :o r+ to turn display of compile/run times off/on
]
[Added collapsing optimisation
eb@cs.st-andrews.ac.uk**20090309112238]
[Added unused argument elimination
eb@cs.st-andrews.ac.uk**20090309004741
Can fit within the optimisation framework, but you need to remember
the transforms so far at each definition for maximum effect.
]
[(Failed) effort at argument erasure
eb@cs.st-andrews.ac.uk**20090308222948
Trying to get it into the same framework as constructor transformations,
but it isn't going to happen that easily.

[Added forcing optimisation

eb@cs.st-andrews.ac.uk**20090227231257]
[Added 'using' syntax
eb@cs.st-andrews.ac.uk**20090226003439
For blocks where lots of things use the same implicit arguments, saving
lots of typing and clutter.
(also allowed forward declaration of datatypes)
]
[Fix conflict
eb@cs.st-andrews.ac.uk**20090107121727]
[Laziness annotations

eb@cs.st-andrews.ac.uk**20081219180726]

[Fix foreign functions for IO
eb@cs.st-andrews.ac.uk**20081102153832]
[Added Ptr primitive
eb@cs.st-andrews.ac.uk**20081102134232]
[Add unsafePerformIO
eb@cs.st-andrews.ac.uk**20081019171546
Mostly meant for pure foreign functions, but of course you're free to abuse
it as you like...
]
[Add flags on functions to denote special behaviour
eb@cs.st-andrews.ac.uk**20081019160020
Specifically, so far:
* %nocg Never generate code when compling
* %eval Evaluate completely before compiling
This allows some 'meta-programs' to be written, which are fully evaluated
before compiling. We use this for defining foreign functions easily.
]
[Record paper changes!
eb@cs.st-andrews.ac.uk**20080916170851]
[Added 'use' tactic
eb@cs.st-andrews.ac.uk**20080916170742
Like 'believe' but instead of just believing the value, adds subgoals for
each required equality proof.
]
[More of paper
eb@cs.st-andrews.ac.uk**20080901161738]
[Added paper macros
eb@cs.st-andrews.ac.uk**20080901094433]
[Starting on paper
eb@cs.st-andrews.ac.uk**20080829091345]

eb@cs.st-andrews.ac.uk**20080826123458]

[Transformation application
eb@cs.st-andrews.ac.uk**20080730125618]
['noElim' flag to allow big data types not to need elimination rules
eb@cs.st-andrews.ac.uk**20080729125140]
[Added __toInt and __toString
eb@cs.st-andrews.ac.uk**20080710151313
Hacky for now, until we work out a nice way of doing coercions between
primitives. But it makes some programs, like those which ask for an int
as input, possible.
]
[If an operator returns a boolean, the compiler had better make code to build a boolean!
eb@cs.st-andrews.ac.uk**20080710145313]
[Deal with weird names that Ivor generates in the compiler
eb@cs.st-andrews.ac.uk**20080709112032]

[Don't crash when there's an error in input!
eb@cs.st-andrews.ac.uk**20080708182610]
[Only allow 'believe' to rewrite values
eb@cs.st-andrews.ac.uk**20080708165140
This way at least the types have to be right before '?=' defined
programs will run.
]
[Added 'believe' tactic
eb@cs.st-andrews.ac.uk**20080708160736
For allowing the testing of programs before a complete proof term
exists. Obviously programs built this way are not trustworthy! They make
use of a "Suspend_Disbelief" function which just invents a rewrite rule
that works, but which doesn't have a proof.
]
[Added '?=' syntax
eb@cs.st-andrews.ac.uk**20080708140505
If you have a pattern clause, and don't know the definite type of the
right hand side, use;
foo patterns ?= def; [theoremName]
This will add a theorem called theoremName which fixes up the type,
and you can prove it later, via :p or with the 'proof' syntax. Useful
if you want to hide details of the proof of a necessary rewriting.

[Added proof token to Lexer
eb@cs.st-andrews.ac.uk**20080516140747
(not doing anything yet, it needs a separate parser)
Also fix minor lexing error, and added ':i' command to drop into Ivor
for debugging purposes.
]
[Added 'normalise' command
eb@cs.st-andrews.ac.uk**20080523140332
Useful if you want to normalise an IO computation without running it.
]
[Small implicit argument change
eb@cs.st-andrews.ac.uk**20080513231721
{a,b,c} now allowed (i.e no need for type label as in {a,b,c:_}
Also, implicit arguments can now, syntactically, only appear at the
left of types of top level declarations (since that is the only place they
make sense with our simple way of handling such arguments).
