Most files are included in this commit due to a changed date in the copyright note. 2023-02-24T22:14:58Z Stefan Eßer se@FreeBSD.org 2023-02-24T22:14:58Z urn:sha1:61e1a12bb6c3bfdb0a4e499c88e8eaa2b548e427 This version adds a command to dc to query whether extended registers are enabled or not. 2023-02-06T21:28:40Z Stefan Eßer se@FreeBSD.org 2023-02-06T21:25:03Z urn:sha1:aaf1213c6f70af0b517f6aa13cd837d3468a7a0d This update contains only documentation changes (new main repository URL and changed mail address of the program author) and changes to the build system that do not affect the FreeBSD base system build. 2023-01-28T20:02:27Z Stefan Eßer se@FreeBSD.org 2023-01-28T20:02:27Z urn:sha1:e7017237c9d842b4cebdcfb13526cd71a2b2836a This is a production release with a new feature and a few bug fixes. The bug fixes include: - A crash when bc and dc are built using editline, but history is not activated. - A missing local in the uint*() family of functions in the extended math library. - A failure to clear the tail call list in dc on error. - A crash when attempting to swap characters in command-line history when no characters exist. - SIGWINCH was activated even when history was not. The new feature is that stack traces are now given for runtime errors. In debug mode, the C source file and line of errors are given as well. 2021-10-04T19:22:35Z Stefan Eßer se@FreeBSD.org 2021-10-04T19:22:35Z urn:sha1:5d58a51571721190681c50d4bd3a1f45e6282d72 This version adds options and functions that allow to print numbers in the open interval (-1 .. 1) with or without a leading 0 digit. Additionally, an option has been added to prevent line wrap and allows to print arbitrarily long results on a single line. 2021-09-19T12:41:20Z Stefan Eßer se@FreeBSD.org 2021-09-19T12:41:20Z urn:sha1:a60ef1802a36f2f2a5611564191440ea1c1e2f17 2021-08-09T20:32:55Z Stefan Eßer se@FreeBSD.org 2021-08-09T20:32:55Z urn:sha1:2f57ecae4b98e76e5d675563785a7e6c59c868c4 This is a new major release with a number of changes and extensions: - Limited the number of temporary numbers and made the space for them static so that allocating more space for them cannot fail. - Allowed integers with non-zero scale to be used with power, places, and shift operators. - Added greatest common divisor and least common multiple to lib2.bc. - Made bc and dc UTF-8 capable. - Added the ability for users to have bc and dc quit on SIGINT. - Added the ability for users to disable prompt and TTY mode by environment variables. - Added the ability for users to redefine keywords. - Added dc's modular exponentiation and divmod to bc. - Added the ability to assign strings to variables and array elements and pass them to functions in bc. - Added dc's asciify command and stream printing to bc. - Added bitwise and, or, xor, left shift, right shift, reverse, left rotate, right rotate, and mod functions to lib2.bc. - Added the functions s2u(x) and s2un(x,n), to lib2.bc. 2021-01-31T19:58:45Z Stefan Eßer se@FreeBSD.org 2021-01-31T19:56:48Z urn:sha1:47a52dc4d48f259ab7d9f9ba6b65f4f2331a22dc 2020-07-07T07:02:33Z Stefan Eßer se@FreeBSD.org 2020-07-07T07:02:33Z urn:sha1:3960d8924a1a0ba2f0f5e8510e73a10ee20d726b This release fixes a regression from traditional bc behavior in FreeBSD with regard to "-e quit" being passed on the command line and add Spanish message catalogs. 2020-06-27T15:03:19Z Stefan Eßer se@FreeBSD.org 2020-06-27T15:03:19Z urn:sha1:1f958cfad78842ab9a1193471589231e25596cb3 These implementations of the bc and dc programs offer a number of advantages compared to the current implementations in the FreeBSD base system: - They do not depend on external large number functions (i.e. no dependency on OpenSSL or any other large number library) - They implements all features found in GNU bc/dc (with the exception of the forking of sub-processes, which the author of this version considers as a security issue). - They are significantly faster than the current code in base (more than 2 orders of magnitude in some of my tests, e.g. for 12345^100000). - They should be fully compatible with all features and the behavior of the current implementations in FreeBSD (not formally verified). - They support POSIX message catalogs and come with localized messages in Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze, and Russian. - They offer very detailed man-pages that provide far more information than the current ones.
