2011-09-15: Fixes to improve package dependency resolution.
3
2011-07-05: Fixed a parser position bug. Parser positions passed by the user
4
were not updated correctly.
6
Internal code beautification.
8
2011-07-04: Internal updates to sync with Jane Street.
10
2011-01-30: Fixed a code generation bug with toplevel entries.
12
Thanks to Yong Lu <lyongu@gmail.com> for the report!
14
2010-12-27: Added support for MoreLabels.Hashtbl and improved reporting of
15
error locations with preprocessor.
17
2010-12-26: Worked around a compiler bug that is expected to be fixed in
18
OCaml 3.12.1. This workaround temporarily removes the interface
19
for module Conv (conv.mli), thus exposing the internals.
20
This should not cause any problems for end users as long as
21
they do not depend on the exported internal representations.
22
The interface will become constrained again as soon as the
23
fixed compiler is out.
25
2010-12-22: Major release.
27
Merged with Jane Street version. This has caused an API-change
28
that requires "open Sexplib.Conv" at the top of files that use the
33
* sexp_of_lazy -> sexp_of_lazy_t
34
* lazy_of_sexp -> lazy_t_of_sexp
36
Some standard library modules are now re-exported with predefined
37
S-expression converters in module Conv.
39
2010-09-25: Fixed inferred types of generated functions when dealing with arrow
42
2010-08-26: Fixed a lexer bug when parsing comments.
44
2010-05-21: Added support for sexp_bool record field annotations.
46
2010-05-18: Improved performance of converting S-expressions to strings.
48
2010-04-12: Changed API of Of_sexp_error exception.
50
2010-04-07: Added of_(big)string_conv_exn functions.
52
2010-04-01: Merged with Jane Street version.
54
Major new features (various functions):
56
* Type-annotated parsing for better error messages
57
* Greatly improved performance of exception converters
59
2009-12-21: Improved saving of files.
61
2009-10-12: Added sexp_array record field extension.
63
2009-09-19: Added missing variant type cases.
65
Fixed handling of variance annotations.
67
2009-09-15: Internal cleanups.
69
2009-07-28: Added better support for conversion of exception types.
71
2009-06-23: Fixed build problem.
73
Thanks to Sylvain Le Gall <gildor@ocamlcore.org> for
76
2009-05-08: Fixed build problems on Windows and OCamlMakefile issues.
78
Thanks to Sylvain Le Gall <gildor@ocamlcore.org> for
81
2009-04-22: Added macro support for all types of vectors, matrices,
84
2009-04-21: Merged with Jane Street version, no user-relevant changes.
86
2009-03-09: Merged with Jane Street version, no user-relevant changes.
88
2009-03-01: Fixed build problem on Mac OS X by updating OCamlMakefile.
90
2009-01-20: Automatically add S-expression pretty-printers to toplevels.
92
2008-09-30: Added a new feature: sexp_opaque. It prevents the need for /
93
use of type converters for a given type in a particular
96
Removed abstract types to unify them with this new concept.
98
2008-09-29: Added a new feature: sexp_list. This is similar to
99
the handling of sexp_option. By default an empty list is
100
assumed for unspecified records using sexp_list as qualifier.
101
Such record fields bound to empty lists will also not be
102
printed anymore for better readability.
104
2008-09-23: Added missing Not_found-exception to standard exception
107
2008-08-20: Removed dependency on threads. Fixed build problems.
109
2008-08-08: Nifty new feature: exceptions can now be converted to
110
S-expressions, too! The "with sexp" syntax extension can be
111
used with exceptions, thus registering a conversion function.
112
A global exception conversion function can then be called
113
to convert an arbitrary exception into an S-expression,
114
which can then be printed out. This should greatly
115
improve readability of uncaught exceptions while making
116
life extremely easy for the developer.
118
Renamed the ParseError exception to Parse_error to be more
119
compliant with Jane Street naming conventions.
121
2008-07-25: Added utilities for conversion error handling. Minor fixes.
123
2008-04-24: Made Sexp-interface manifest.
125
2008-03-20: Fixed META-file (missing num dependency).
127
2008-03-17: Improved META-file.
129
2008-03-13: Fully allow function types in converters. Raise runtime
130
exceptions on converting from S-expressions instead when
131
function type encountered.
133
2008-02-11: Fixed code generation problems with variance annotations
134
in signatures, and empty types.
136
2007-12-17: Added support for generating signature entries for
137
S-expression converters. Thanks to Till Varoquaux
138
<till.varoquaux@gmail.com> for the patch!
140
2007-11-29: Added support for converting big_int, nat, num, and ratio.
142
2007-11-26: Added support for parsing from bigstrings (char bigarrays).
144
2007-11-02: Added syntax support for option types to use the ordinary
145
sum type syntax. This should improve readability.
146
The old syntax will be accepted, too, if
147
Conv.read_old_option_format is set to true (this is
148
currently the default). The old format will be used for
149
writing if Conv.write_old_option_format is true (currently
150
the default). The old syntax is deprecated and will
151
probably not be supported by default in the near future.
152
Reading new-style option values will always succeed.
154
2007-09-14: Fixed bug in S-expression preprocessor concerning record
157
2007-08-06: Added support for converting functions to S-expressions.
159
2007-07-20: Fixed position information and improved speed of S-expression
160
parser. Fixed S-expression macro bug concerning contained
161
polymorphic variants.
163
2007-06-28: Improved Sexplib code generation.
165
2007-06-22: Fixed escaping bug in S-expression parser.
167
2007-06-01: Added correct handling of recursive types + test case.
169
2007-04-18: Added missing conversion functions from S-expressions to
172
2007-03-21: Updated OCamlMakefile.
174
2007-03-02: Improved error messages when parsing illegal type definitions.
176
2007-01-30: Added triple conversions.
178
2006-11-22: Updated OCamlMakefile.
180
2006-10-13: Improved checking of records for extra or duplicate fields.
182
2006-09-06: Added support for polymorphic record fields.
184
2006-09-05: Added support for manifest types.
186
2006-08-16: Improved error messages.
188
2006-07-28: Added a new, hand-written S-expression parser that supports
189
partial parsing and should be approx. 10x faster than the
192
2006-06-20: Fixed a code generation problem leading to compilation
193
errors concerning the use of type aliases within polymorphic
194
variant type definitions.
196
This fix also solves potential erroneous appearances of
197
backtracking exceptions in user code.
199
2006-03-21: Added -for-pack option to Makefile and cleaned up
200
distribution for a new public release.
202
2006-03-13: Sexplib now accepts capitalized booleans.
204
2006-03-03: Added customizable indentation levels.
205
Improved documentation.
206
Fixed API-problem concerning backward compatibility.
208
2006-03-03: Added customizable indentation levels.
209
Improved documentation.
211
2006-03-01: Added a missing flush for string conversions with a buffer.
213
2006-02-08: Eliminated unused variable warnings in Sexplib-generated code.
215
2006-01-11: Added functions for pretty-printing to buffers. Improved
216
performance of outputting S-expressions to channels.
218
2006-01-09: Added functions load_sexp and load_sexps.
220
2006-01-04: Changed float conversion from %E to %G (more readable).
222
2005-12-28: Made machine representation for S-expressions more compact
224
2005-12-15: Fixed a problem appearing with OCaml-release 3.08.4: CamlP4
225
obviously performs more strict checking on some constructs
226
now and crashed with an exception when generating
227
S-expression code for records containing only one field
228
("singleton tuple problem"). This problem is fixed now.
230
2005-11-25: Fixed problem with type variables that could not be generalized.
232
2005-11-23: Added a missing case in type definitions (path alias)
234
2005-11-17: Major release: 2.0
236
Fixed a major design problem. The user now has to pass lex
237
buffers instead of channels to input-functions. Reason:
238
trailing characters in channels were lost due to ocamllex
239
buffering them in the non-exposed lex buffer. This lex
240
buffer is now exposed. The functions have been renamed
241
("input_X" -> "scan_X") to reflect this change.
243
2005-11-16: Added label to conversion function "input_cnv_sexps".
245
2005-11-11: Fixed a bug in the pretty-printer: strings in atoms were
246
not escaped in the function "to_string_mach" (and therefore
249
2005-11-07: Initial release.
