This update fixes a few bugs:
- Improper response to double SIGINT with editline.
- Not letting libedit handle terminal size changes.
- A dc crash from improperly handling an error.
- A duplicate check for reference arrays.
- Build failures with GCC 15.

This is a production release to fix three bugs, none of which
affects well formed scripts on FreeBSD:
The first bug is that bc/dc will exit on macOS when the terminal
is resized.
The second bug is that an array, which should only be a function
parameter, was accepted as part of larger expressions.
The third bug is that the value stack for dc was cleared on any error.
However, this is not how other dc behave. To bring dc more in line
with other implementations, this behavior was changed. This change is
why this version is a new major version.

This update fixes a potential issue when flushing stdout on exit
fails: longjmp could use an uninitialized target address variable.
Most files are included in this commit due to a changed date in
the copyright note.

This update fixes a bug that line breaks in printed numbers may not
match the line length set by the user. The value is printed correctly,
just not split as specified in some situations.

This update improves the implementation of the power function p() and
adds 3 new functions to the extended math library: min(), max(), and
i2rand().
|
| |
|
|
|
|
| |
This update removes printing of a leading zero in scientific or
engineering output modes (which are an extended feature of this
implementation).

This release that fixes an infinite loop bug in the (non-standard)
extended math library functions root() and cbrt(), fixes a bug with
BC_LINE_LENGTH=0, and adds the fib() function to the extended math
library to calculate Fibonacci numbers.

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.

This is a production release that fixes a bug.
The bug was that if an array element was used as a parameter, and then
a later parameter had the same name as the array whose element was
used, bc would grab the element from the new array parameter, not the
actual element from before the function call.

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.

This is a production release that fixes a discrepancy from the bc
standard, a couple of memory bugs, and adds new features.
The discrepancy from the bc standard was with regards to the behavior
of the quit command. This bc used to quit whenever it encountered quit
during parsing, even if it was parsing a full file. Now, bc only quits
when encountering quit after it has executed all executable statements
up to that point.
This behavior is slightly different from GNU bc, but users will only
notice the difference if they put quit on the same line as other
statements.
The first memory bug could be reproduced by assigning a string to a
non-local variable in a function, then redefining the function with
use of the same non-local variable, which would still refer to a
string in the previous version of the function.
The second memory bug was caused by passing an array argument to the
asciify() built-in function. In certain cases, that was wrongly
allowed, and the interpreter just assumed everything was correct and
accessed memory. Now that arrays are allowed as arguments (see below),
this is not an issue.
The first feature was the addition of the is_number() built-in
function (u in dc) that returns 1 if the runtime argument is a number
and 0 otherwise.
The second feature was the addition of the is_string() built-in
function (t in dc) that returns 1 if the runtime argument is a string
and 0 otherwise.
These features were added because I realized that type-checking is
necessary now that strings can be assigned to variables in bc and
because they've always been assignable to variables in dc.
The last added feature is the ability of the asciify() built-in
function in bc to convert a full array of numbers into a string. This
means that character-by-character printing will not be necessary, and
more strings than just single-character ones will be able to be
created.

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

This release fixes two parse bugs when in POSIX standard mode. One of
these bugs was due to a quirk of the POSIX grammar, and the other was
because bc was too strict.
|
| |
|
|
|
| |
This version is imported only for documentary purposes since it does
not contain any changes that are relevant for the FreeBSD base system.
|
| |
|
|
|
| |
This update fixes a parser issue, which in special situations could
reject syntactically correct if statements.
|
| |
|
|
|
|
|
|
| |
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.

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.

This version makes dc exit after processing all commands passed via -e or -f
instead of waiting for more input on STDIN (add "-f -" to the command line
to emulate the behavior of versionm 3.1.3 and earlier, if desired).
The version and copyright message are no longer printed for interactive
sessions as was the case with the prior implementation in the FreeBSD base
system.

with regard to "-e quit" being passed on the command line and add Spanish
message catalogs.

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.
