Compile-time expansion utility.
+
__Authors:__ : Ulf Wiger ([`ulf@feuerlabs.com`](mailto:ulf@feuerlabs.com)).

## Description ##
-
-
This module serves as an example of parse_trans-based transforms,
but might also be a useful utility in its own right.
The transform searches for calls to the pseudo-function
`ct_expand:term(Expr)`, and then replaces the call site with the
result of evaluating `Expr` at compile-time.
-
-
For example, the line
-
-
`ct_expand:term(lists:sort([3,5,2,1,4]))`
-
-
would be expanded at compile-time to `[1,2,3,4,5]`.
-
-
ct_expand has now been extended to also evaluate calls to local functions.
See examples/ct_expand_test.erl for some examples.
-
-
A debugging facility exists: passing the option {ct_expand_trace, Flags} as an option,
or adding a compiler attribute -ct_expand_trace(Flags) will enable a form of call trace.
-
`Flags` can be `[]` (no trace) or `[F]`, where `F` is `c` (call trace),
`r` (return trace), or `x` (exception trace)'.

Parse transform for generating record access functions.

This parse transform can be used to reduce compile-time
dependencies in large systems.
-
In the old days, before records, Erlang programmers often wrote
access functions for tuple data. This was tedious and error-prone.
The record syntax made this easier, but since records were implemented
fully in the pre-processor, a nasty compile-time dependency was
introduced.
-
This module automates the generation of access functions for
records. While this method cannot fully replace the utility of
pattern matching, it does allow a fair bit of functionality on
records without the need for compile-time dependencies.
-
Whenever record definitions need to be exported from a module,
inserting a compiler attribute,
`export_records([RecName|...])` causes this transform
to lay out access functions for the exported records:
-
As an example, consider the following module:
-```
+```erlang
-module(test_exprecs).
-export([f/0]).
- -compile({parse_transform, exprecs}).
- -record(r, {a = 0 :: integer(),
- b = 0 :: integer(),
- c = 0 :: integer()}).
- -record(s,{a}).
- -export_records([r,s]).
- f() ->
- {new,'#new-r'([])}.
-```
-
-
-
-Compiling this (assuming exprecs is in the path) will produce the
-following code.
-
-
-
-```
-
- -module(test_exprecs).
- -compile({pt_pp_src,true}).

This module contains some useful utility functions for inspecting
the results of parse transforms or code generation.
The function `main/1` is called from escript, and can be used to
pretty-print debug info in a .beam file from a Linux shell.
