Most files are included in this commit due to a changed date in the copyright note. 2023-03-03T22:15:06Z Stefan Eßer se@FreeBSD.org 2023-03-03T22:15:06Z urn:sha1:0ff539eb7ca570d65a23a7ad13a91a673d89abcf This version contains a fix for an issue that can affect complex bc scripts that use multiple read() functions that receive input from an interactive user. The same value could be returned multiple times. 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. 2022-08-30T18:37:36Z Stefan Eßer se@FreeBSD.org 2022-08-30T18:35:22Z urn:sha1:161a37cc712bae177402d7143cb21b7d085c69c7 Changes relative to the previous version in FreeBSD: - Fix error message on certain syntax errors. - Add digit clamping (build option and run-time option) - Make -l options no longer overridee scale value set with -S 2022-06-11T09:50:28Z Stefan Eßer se@FreeBSD.org 2022-06-11T09:50:28Z urn:sha1:5bdd626528a2bb3e341e283b2eb279235997b8f4 This version adds support for command line editing and history using the editline or readline libraries in addition to the line editing features available in previous versions. 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. 2021-08-09T20:32:55Z 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 2020-11-26T17:27:07Z Stefan Eßer se@FreeBSD.org 2020-11-26T17:27:07Z urn:sha1:2e4772e82335c32e07d0605e5edefb0ac6ea857b
