with newer versions of clang under windows works better.
- Tests for integer parse have been added to chkexc.sd7.
- The function doRemove in chkccomp.c has been improved to write
nothing to the console.
- The function showErrors has been added to chkccomp.c.
- In actutl.c the functions searchAction and findAction have been
improved to use fewer parameters and the function getActIllegal
has been added.
- In chkccomp.c the function writeReadBufferEmptyMacro has been
improved to optionally use _get_stream_buffer_pointers() to define
the macro read_buffer_empty.
- The operator 'char conv' has been improved to check if the integer
fits in a character.
- Documentation comments have been improved in float.s7i, poll.s7i,
actlib.c actutl.c, big_gmp.c, big_rtl.c, bln_rtl.c, bst_rtl.c,
chr_rtl.c, cmd_rtl.c, dir_dos.c, dir_win.c, drw_rtl.c, fltlib.c,
flt_rtl.c, int_rtl.c, pcs_rtl.c, pollib.c, pol_sel.c, pol_unx.c,
prg_comp.c, rfl_data.c, setlib.c, set_rtl.c and str_rtl.c.
- Calls of logFunction have been added to functions in cmdlib.c and
flt_rtl.c,.
- Calls of logError have been added to functions in actlib.c,
biglib.c, bstlib.c, chrlib.c, cmdlib.c, drwlib.c, fillib.c,
fltlib.c, hshlib.c, intlib.c, pcslib.c, pollib.c, prglib.c,
rfl_data.c, rfllib.c, sctlib.c, setlib.c, strlib.c and typlib.c.
Changes:
- The makefile mk_clangw.mak has been added. This makefile supports
compilation under Windows with the clang compiler.
- The experimental function parentDir has been added to osfiles.s7i.
- The experimental function getServerCertificate has been added to
tls.s7i.
- The compiler (s7c) has been improved to use the function
strAppendN, when two or more strings are appended to a string.
- Tests for string append (operator &:= ) have been added to
chkstr.sd7.
- The function strAppendN has been added to str_rtl.c.
- The function strCopy in str_rtl.c has been simplified.
- The program chkccomp.c has been improved to write a definition of
CHAR_BIT, when it is not defined in limits.h.
- Several files have been changed to use CHAR_BIT instead of the
literal 8.
- in chkccomp.c several string literals have been changed to wide
string literals (e.g. L"abc" instead of "abc").
- In several files integer literals have been replaced by contants or
#define macros.
- The function __mulodi4 has been added to int_rtl.c. This function
is used by clang under Windows, but unfortunately is not part of the
runtime library. This situation is recognized by chkccomp.c and the
function __mulodi4 in int_rtl.c is used instead.
Changes:
- The function fltCmp in flt_rtl.c has been improved to work correct
in the case that isnan returns neither 0 nor 1 (Many thanks go to
Arnel L. for reporting this problem).
- The function determineGetaddrlimit in chkccomp.c has been improved
to include <sys/types.h> before <sys/resource.h>. FreeBSD needs
that to work correctly (Many thanks go to Pietro Cerutti for
providing a fix and explaining the background).
- The function getOsCwd has been added to cmd_rtl.c. With this
function it is possible to read (e.g. under Linux) a current
working directory that is longer than PATH_MAX.
- Documentation comments have been improved in encoding.s7i.
- The program chkccomp.c has been improved to write definitions of
USE_DIRENT, USE_DIRWIN, OS_WIDE_DIR_INCLUDE_DIR_H, os_DIR,
os_dirent_struct, os_opendir, os_readdir, os_closedir,
INCLUDE_SYS_UTIME, os_utimbuf_struct, USE_ALTERNATE_UTIME,

os_getcwd, os_mkdir, os_rmdir, OS_CHMOD_INCLUDE_IO_H, os_chmod,
os_remove, os_rename, os_system, os_fopen, os_popen, os_pclose,
DEFINE_WGETENV, os_getenv
- The functions keys_helem and values_helem in hshlib.c and
hsh_rtl.c have been improved to use a loop instead of a tail
recursion. For compilers that don't recognize the tail recursion
this results in a speed improvement (Gcc recognizes tail
recursions so there is no speed improvement).
- The functions free_helem and free_hash in hsh_rtl.c have been
improved to stop searching for helems as soon as the last helem
has been freed.
- The functions helem_data_to_list and helem_key_to_list have been
improved to use a loop instead of a tail recursion (see above).
Changes:
* The function setSearchPath has been added to the library
process.s7i.
* The compiler has been improved to write an error message, when the
sets of a case-statement overlap. Until now this situation was only
recognized by the C compiler.
* The interpreter has been improved to raise an exception, when the
current value of a case-statement is element of two sets.
* There have been changes in the libraries makedata.s7i and make.s7i.
* The macro expansion in makedata.s7i has been changed. Now all macro
expansions (except the expansions of internal macros) are done with
the function applyMacros.
* In makedata.s7i the function applyMacros has been improved to
process the makefile macro functions wildcard, error and warning.
* The functions evalFunction and getMacro, that where used to do
macro expansion when the makefile is read, have been removed.
* The code to read the definition of recursively expanded variables
has been changed to do no macro expansion. This macros are expanded
when they are used.
* The library make.s7i has been improved to read the parameters
for the commands rm, cp, and mv as Unix shell parameters (with the
function getUnixCommandParameter).
* The library make.s7i has been improved to read the parameters
for the commands del, copy, xcopy and move as Dos/Windows batch
parameters (with the function getDosCommandParameter).
* Interpreter and compiler have been improved to support the action
CMD_SET_SEARCH_PATH.
* The batch file bin/call_gcc.bat has been changed to work correctly,
when it is called from any directory.
* Writing error messages in error.c has been changed to use prot_...
functions instead of printf.
Changelog:
* The chapter about files in the manual has been improved.
* Variants of the for-each-loop with an until condition have been
added to array.s7i.
* The parse operator for characters has been improved to accept only
strings with a length of 1.
* The function trimValue has been introduced. This function trims a
string such that it can be converted to a specified type.
* The exception handlers for RANGE_ERROR have been removed from the
functions read and readln in enable_input.s7i. The functions read
and readln now raise range RANGE_ERROR when the conversion to the
target type fails.
* Occurances of io_ok, io_error, io_empty and io_filled have been
removed from the libraries. This undocumented feature was not used
for years. The function succeeds and the functions read and readln
with default value are better suited for error checking, when data
is read.
* The exception handlers in interpreter and compiler have been
improved to allow an otherwise part.
* The function succeeds has been introduced. This function executes
a statement and returns TRUE when no exception occurs.
* The example programs nicoma.sd7 and savehd7.sd7 have been improved
to use the new function succeeds.
* The parse operator for float has been changed to raise RANGE_ERROR
when leading whitespace is found.
* The library make.s7i has been improved to accept the commands
erase, xcopy, mv, move and rem.
* The library makedata.s7i has been improved to accept the macro
functions subst and patsubst.
* The reading of rules in makedata.s7i has been improved to read
commands without macro substitution. The macros in commands are
substituted just before the commands are executed.
* The make functions in make.s7i have been changed to raise
FILE_ERROR when a command fails.
* The function applyMacros in makedata.s7i has been improved to
accept macro functions and the shorthands of patsubst.
* The function replaceSuffixes in makedata.s7i has been improved to
accept pattern substitution with the % character.
* In the library make.s7i the logging has been removed from the
functions doRm, doCp, doPwd, doEcho, doCd, doMake, doOneCommand,
doCommands and processCommand.
* The program chkflt.sd7 has been adjusted to work with the strict
parse operator for float.
* Interpreter and compiler have been improved to support the actions
PRC_BLOCK_CATCH_ALL and PRC_BLOCK_OTHERWISE.
* The program sudo.c has been improved to work without upper limit
for the parameter length.
* The functions checkIfOutsideRange and negate have been added to
int_act.s7i.
Changes:
* The handling of ctrl-c has been changed to work better under
windows.
* The runtime of the function intPowOvfChk in int_rtl.c has been
reduced to 57% (measured with gcc and valgrind).
* The generation of code in the compiler for the action INT_POW has
been improved. When the base is a negative power of two the
exponentiation is done with a shift instead of a call of intPow
(respectively intPowOvfChk).
* The overflow checking for INT_POW in the compiler has been
improved. When base or exponent is known the overflow checking is
done with inline code and intPow is called instead of intPowOvfChk.
* Documentation comments have been added to bitsetof.s7i
* Tests for ** have been added to chkint.sd7 and chkovf.st7
* The tests for * and *:= in chkovf.st7 have been reorganized.
* An interrupt_flag has been introduced in the interpreter. This flag
is used for exception handling and for signal handling. Exceptions
set interrupt_flag and fail_flag (with the macro set_fail_flag).
Signals set only the interrupt_flag (file sigutl.c). The
interrupt_flag is handled in exec_action (file exec.c).
* The functions signal_name, handle_signals, handle_segv_signal,
handle_term_signal and activate_signal_handlers in sigutl.c have
been improved.
* The functions continue_question, write_curr_position and
show_signal in runerr.c have been improved.
* The functions handle_int_signal, readChar, doGetcFromTerminal,
doGetsFromTerminal, doLineRead, doLineReadFromTerminal, doWordRead,
doWordReadFromTerminal, filGetcChkCtrlC, filGetsChkCtrlC,
filHasNextChkCtrlC, filLineReadChkCtrlC and filWordReadChkCtrlC
have been added to fil_rtl.c. This functions support reading from
a terminal with a check for ctrl*c. This functions are used by the
interpreter (file intlib.c).
* Tracing has been added to functions in int_rtl.c.
* Configuration defines for CTRL_C_SENDS_EOF,
SIGNAL_HANDLER_CAN_DO_IO and INT64TYPE_NO_SUFFIX_BUT_CAST have been
added to makefiles.
Changes:
* The compiler has been improved to generate overflow checking code
by default. The generation of overflow checking code can be
switched off with the option -so.
* The exception OVERFLOW_ERROR has been introduced. It is raised by
the interpreter and by compiled programs when an integer overflow
occurs.
* A paragraph about integer overflow and the installation of Seed7
has been added to the FAQ.
* The chapter about exceptions in the manual has been improved.
* The program chkovf.sd7, which checks the recogition of integer
overflows, has been added.
* Checks for +, -, *, rem, mod, <<, +:=, -:=, *:=, succ, pred, incr
and decr have been added to chkint.sd7.
* Checks for the lpad operator have been added to chkstr.sd7.
* The compiler option -r has been replace by the option -sr.
* The program calc7.sd7 has been improved to report MEMORY_ERROR and
OVERFLOW_ERROR.
* The library make.s7i has been improved such that make7.sd7 accepts
echo (and echo.) statements without parameters.
* The function eof has been defined for the type tlsFile in tls.s7i.
* The function gets in tls.s7i has been improved.
* The function getHttp in gethttp.s7i has been improved to avoid an
endless loop when eof has been reached.
* The function memcpy_from_strelem has been added to striutl.c. This
function uses loop unrolling inspired by Duff's device and a trick
with a binary or (|=) to check for allowed values.
* The functions filWrite, socWrite and bstParse have been changed
to use memcpy_from_strelem. The reduction in runtime has been
measured with gcc and valgrind. The runtime of filWrite, socWrite
and bstParse has been reduced to 53%, 61% and 56% respectively.
* Documentation comments have been added to integer.s7i, bin32.s7i,
intlib.c and striutl.c.
* The compiler has been improved to generate overflow checking code
for *, <<, >>, *:=, <<:= and >>:= .
* The generation of overflow checking code for the operators rem and
mod has been improved.
* Checks for overflow, division by zero, numeric error and index out
of bounds in compiled programs now use the macros ovfChk, divChk,
numChk and idxChk. This macros inform the C compiler about the
unlikeliness of an exception.
* The function fltIPow has been improved to avoid a signed integer
overflow, when the exponent is the most negative integer.
* The primitive actions INT_ULSHIFT and INT_ULSHIFT_ASSIGN have been
added and supported in interpreter and compiler.
* A version of the function uint_rand, which uses 128-bit integers,
has been added to int_rtl.c.
* The function raise_error3 in runerr.c has been renamed to
interprRaiseError.
* The configuration values INT128TYPE, UINT128TYPE and MACRO_DEFS
have been added to cc_conf.s7i. The configuration value
SIGILL_ON_OVERFLOW has been replaced with OVERFLOW_SIGNAL.
* The functions constValueIsEqual, checkRangeFromZero,
process_const_int_lshift, process_const_int_lshift_assign,
process_const_int_rshift_assign, process_const_int_mult,
process_const_int_mult_assign, process_const_int_ulshift_assign,
process_const_int_ulshift and process_const_int_urshift_assign
have been added to int_act.s7i.
* The function intExpr in chkbig.sd7, chkexc.sd7, chkint.sd7 and
chkstr.sd7 has been changed to make sure that the C compiler
cannot evaluate it at compile time.
* The runtime of the functions str_lpad, strLpad and strLpadTemp has
been improved.
Changes:
* The interpreter has been improved to recognize integer overflow.
Now the exception NUMERIC_ERROR is raised, when a program triggers
an integer overflow. The checks for overflow are done in software,
but the overhead is small. With overflow checks the interpreter
needs 0.5% (zero point five percent) more run-time to execute the
program chkint.sd7 (verified with gcc and valgrind).
* A chapter about the Seed7 Structured Syntax Description (S7SSD)
has been added to the manual.
* The for-until-loops in bitset.s7i and bitsetof.s7i have been
improved such that the for-variable has the correct value, when it
is used in the until-condition.
* The function replaceN has been added to string.s7i. This function
does replacements until no occurance of the target string is left.
This function is used by toStdPath to replace multiple occurances
of a character by one occurance (replace("/a///b////c", "//", "/")
returns "/a/b/c").
* The program calc.sd7 has been renamed to calc7.sd7.
* The program calc7.sd7 has been changed to accept the commands
'quit' and 'exit'. This commands can be used to exit the program.
The possibility to leave the program with an empty input line has
been removed.
* The program calc7.sd7 has been improved to write the name of the
exception, when it has been raised.
* The compiler has been improved to allow the generation of overflow
checking code. Overflow checking code can be generated for the
operators +, -, **, +:= and -:= and the functions abs, succ, pred,
incr and decr. Until the rest of the functions is implemented and
enough tests have been added to chkint.sd7 the functionality is
switched off.
* The template FOR_UNTIL_DECLS has been added to forloop.s7i. This
template defines for-loops with a condition.
* The function abs has been moved from the library math.s7i to the
library float.s7i.
* Checks for addition, subtraction, multiplication, power and abs
have been added to chkint.sd7.
* In the compiler the statements to write the C prototypes have been
moved from s7c.sd7 to functions in the files comp/xxx_act.s7i
(xxx is the abbreviation for the corresponding primitive type).
* The functions getReference getParameterAsReference have been added
to comp/expr_util.s7i.
* The function isit_bool from objutl.c has been replaced by the macro
isit_bool (defined in objutl.h). This improves the speed of the
interpreter.
* The function set_card has been improved to call setCard, which
computes the cardinality of a set much quicker.
Changes:
* The makefile mk_freebsd.mk has been changed to work with the new
version of chkccomp.c. Thanks go to Pietro Cerutti for pointing out
the problem.
* The self extracting Seed7 package for windows has been improved to
use gcc version 4.8.1 instead of 4.5.0.
* The new function removeTree, which removes a directory tree, has
been introduced in osfiles.s7i. The function removeAnyFile, which
has been used for the same purpose, is deprecated. Deprecated
functions will be removed in a future version.
* Checks for hash tables with character keys have been added to
chkhsh.sd7.
* The test program "chkcmd.sd7" has been added. This program checks
functions that copy, move and remove files. Note that windows has
race conditions when files are copied, moved and removed quickly in
succession. This bug of windows cannot be fixed in a runtime
library.
* The function temp_name_in_dir has been added to striutl.c.
* The typedef of socketType in common.h has been changed such that
socketType is always int.
* Functions in soc_rtl.c, pol_sel.c and pol_unx.c have been changed
to use the type os_socketType.
* Tracing statements in hsh_rtl.c, cmd_rtl.c, drw_win.c and drw_x11.c
have been changed to use the FMT_ strings from common.h. This way
the tracing is more portable.
* Under Windows the functions cmdRemoveFile and cmdRemoveTree now
rename a file before it is removed. When the renaming fails the
directory is left intact. This avoids half removed directory trees
under Windows, when a process has the current working directory
somewhere in the directory that is to be removed. The renaming also
lowers the probability of race conditions under Windows, but they
still can happen.
* The function checkMoveDirectory has been added to chkccomp.c.
* The target make7 has been added to the makefiles. With 'make make7'
an executable of the make7 program is generated and placed in
seed7/bin.
* The compiler has been refactored. Code has been moved from s7c.sd7
to several compiler libraries. The compiler libraries are licensed
with the GPL and can be found in seed7/lib/comp. The refactored
compiler is the first compiler of the 3.0 series.
* The chapter in the manual about the foreign function interface has
been improved.
* Checks for parse and str have been added to chkflt.sd7 and
chkint.sd7.
* In chkccomp.c code has been moved from main() to the new functions
numericSizes and numericProperties.
* Usages of the macro logError have been added to cmd_rtl.c and
cmd_unx.c.
* The stack size defined in mk_mingc.mak, mk_mingw.mak, mk_msys.mak
and mk_nmake.mak has been changed from 4194304 to 8388608.
* The function cstri_buf_to_stri has been added to striutl.c.
* The generation of float literals in the compiler has been improved
to avoid that precision is lost.
* Interpreter and compiler have been improved to support the actions
BLN_EQ and BLN_NE.
Changes:
* Errors in con_wat.c and drw-dos.c have been fixed (thanks to
"Rugxulo" for the help to fix them).
* The function str in duration.s7i has been improved to work for
negative durations.
* The library tar.s7i has been improved to work with the old file
format that does not use the magic value "ustar".
* The function bigToInt16 has been added to big_rtl.c and big_gmp.c.
* The macros with format strings in common.h have been renamed.
Now the macros have shorter names (starting with FMT_ and F_).
The macros define formats for various integer sizes. This formats
are independend from the actual C compiler and C runtime library.
* The function bigLog10 in big_rtl.c has been improved to work
correctly when BIGDIGIT_SIZE is small.
* The program chkccomp.c has been improved to define
LOCALTIME_WORKS_SIGNED, when localtime can process negative times.
* The program chkccomp.c has been improved to write the define
directives to the file specified with the first parameter.
* The function intParse in int_rtl.c has been improved to accept the
most negative number.
* The function timSetLocalTZ in tim_rtl.c has been changed to avoid
raising an exception when LOCALTIME_WORKS_SIGNED is not defined and
the time is before 1970-01-01. In this case the daylight saving
time flag is set to FALSE.
Changes
* The answer concerning Unicode support in the FAQ has been improved.
* The chapters in the manual that describe the types integer,
bigInteger, rational, bigRational and float have been improved.
* The function log10 has been added to the libraries integer.s7i and
bigint.s7i. This function computes the truncated base 10 logarithm.
* The operator sci has been added to the libraries integer.s7i,
bigInteger.s7i, bigrat.s7i and rational.s7i. This operator converts
a number to a string in scientific notation. Halfway cases are
rounded away from zero.
* The function round10 has been added to the libraries rational.s7i
and bigrat.s7i. It rounds halfway cases away from zero.
* The function str has been improved in the libraries rational.s7i
and bigrat.s7i. Now the function converts to a string with a
decimal representation (e.g.: "1.25"). When repeating decimals are
recognizend they are enclosed in parentheses.
* The operator digits has been improved in the libraries rational.s7i
and bigrat.s7i. Now the operator rounds halfway cases away from
zero.
* Documentation comments have been improved in bigint.s7i, float.s7i,
rational.s7i, bigrat.s7i, char.s7i, big_gmp.c and fltlib.c.
* Definitions of the constants integer.first and integer.last have
been added to integer.s7i.
* In bigrat.s7i and rational.s7i the function reduce has been
improved to accept Infinity and NaN.

* The compiler has been improved to use the functions
bigIPowSignedDigit and bigGrowSignedDigit to optimize the operators
**, +:= and -:= for bigInteger operands.
* The compiler has been improved to support the actions INT_LOG10 and
BIG_LOG10.
* The function isPureFunction in the compiler has been improved.
* The functions bigGrowSignedDigit and bigLog10 have been added to
big_rtl.c and big_gmp.c.
* The program chkccomp.c has been improved to write definitions of
the macros isinf, DOUBLE_DECIMAL_EXPONENT_DIGITS, FLOAT_STR_FORMAT,
FLOAT_STR_LARGE_NUMBER, DOUBLE_STR_FORMAT, DOUBLE_STR_LARGE_NUMBER,
FLOAT_MANTISSA_FACTOR, FLOAT_MANTISSA_SHIFT, DOUBLE_MANTISSA_FACTOR
and DOUBLE_MANTISSA_SHIFT.
* The functions fltDgts and fltSci in flt_rtl.c have been changed to
raise RANGE_ERROR when the precision is negative.
* The function fltStri in flt_rtl.c has been improved to write a
reasonable number of fractional digits.
* The functions getMantissaAndExponent, setMantissaAndExponent and
doubleToCharBuffer have been added to flt_rtl.c.

* The function stri_to_wstri has been renamed to stri_to_utf16.
* The functions stri_to_wstri_buf and wstri_buf_to_stri have been
added to striutl.c.
Changes:
* The chapter in the manual about the foreign function interface has
been improved.
* A paragraph about regular expressions and lexical scanner functions
has been added to the FAQ.
* The handling of the actions CHR_CLIT and INT_STRI in the compiler
has been improved. The string buffers for chrCLitToBuffer and
intStrToBuffer use the correct alignment now.
* In big_rtl.c the functions bigParseBasedPow2 and bigParseBased2To36
have been added and bigParseBased has been changed to call them.
This improves the conversion of a string to a bigInteger, when the
base is a power of two. Valgrind measurements of the function
bigParseBased in chkbig.sd7 show a speed improvement with a factor
of 239.
* The macros memcpy_to_strelem and memset_to_strelem (defined in
striutl.h) have been turned into functions (defined in striutl.c).
* The unrolling in memcpy_to_strelem and memset_to_strelem has been
changed from 8 times to 32 times. This improves the performance
for big data amounts by 16% (Measured with valgrind and gcc).
* Usages of the macros memcpy_to_strelem and memset_to_strelem in
bst_rtl.c, fil_rtl.c, soc_rtl.c and str_rtl.c have been turned into
usages of the corresponding functions.
* Calls of cstri_expand, ustri_expand, cstri_expand2 and
ustri_expand2 in analyze.c, chr_rtl.c, flt_rtl.c, infile.c,
str_rtl.c and striutl.c have been turned into calls of
memcpy_to_strelem.
* The functions (macros) cstri_expand, ustri_expand, cstri_expand2
and ustri_expand2 have been removed from striutl.c and striutl.h.
* The functions doCompileAndLink, compileAndLinkWithOptionsOk,
compileAndLinkOk, appendToFile and detemineDatabaseDefines have
been added to chkccomp.c. The function compilationOkay has been
replaced by compileAndLinkOk.
* The chapters in the manual about primitive actions and the foreign
function interface have been improved.
* The names of the C types used in interpreter and runtime library
have been refactored to use camel case.
* The elements in the unions valueUnion (in data.h) and rtlValueUnion
(in data_rtl.h and s7c.sd7) have been refactored to use names with
camel case.
* The library bigint.s7i has been changed to define the operators
radix and RADIX with the actions BIG_radix and BIG_RADIX. This
results in a significant performance improvement when large numbers
are converted.
* Interpreter and compiler have been improved to support the actions
BIG_radix and BIG_RADIX.
* Testcases for the operators radix and RADIX have been added to
chkbig.sd7.
* The compiler has been improved to do an optimization for the action
INT_MDIV when the divisor is known at compile time. When the
dividend is known to be positive or zero it is casted to an
unsigned integer and the quotient is casted back to a signed
integer. Dividing an unsigned integer by a constant is known to be
faster than dividing a signed integer.
* The functions bigRadix, bigRadixPow2, bigRadix2To36 and
uBigDivideByDigit have been added to big_rtl.c
* The function bigRadix has been added to big_gmp.c.
* The functions stri_to_cstri8_buf and cstri8_buf_to_stri have been
added to striutl.c.
* In traceutl.c the function mapTraceFlags has been improved to work
correctly when the parameter trace_level defines several options.
* The function printTraceOptions has been added to traceutl.c.
* In arr_rtl.c the definition of getArgv has been improved to use
less #ifdef directives in the function body.
Changes:
* The documentation file doc/install.txt has been improved to describe
the command 'make install'.
* The chapter about the foreign function interface in the manual has
been improved.
* In striutl.h the macros os_stri_alloc and os_stri_free have been
improved to use a stack like allocation. Allocations done with
os_stri_alloc must be freed with os_stri_free in the reverse order
of their creation. The new macros reduce the runtime of
stri_to_os_stri and cp_to_os_path to 66% of the old time. This
reduces the time used by operating system calls. E.g.: The CPU time
used by the program sydir7 is reduced to 83% of the old time.
* The targets 'install' and 'uninstall' have been added to makefile,
mk_linux.mak, mk_osx.mak, mk_clang.mak, mk_cygw.mak, mk_mingw.mak,
mk_msys.mak, mk_nmake.mak, mk_msvc.mak, mk_bcc32.mak and
mk_bccv5.mak.
* The program setwpath.c has been added. This program sets the search
path (PATH variable) under Windows.
* The obsolete target 'hi' has been removed from the makefiles.
* The functions initEmulatedCwd, cmdSetenv (both in cmd_rtl.c),
setEmulatedCwd (in striutl.c) and freeArgVector (in cmd_unx.c) have
been adjusted to work with the stack like allocation of
os_stri_alloc and os_stri_free.
* The functions heapAllocOsStri and heapFreeOsStri have been added to
striutl.c.
* Usages of MAX_SYMLINK_PATH_LENGTH in cmd_rtl.c have been replaced
with MAX_OS_STRI_LEN.
Changes:
* The function setSockOpt and the constant SO_REUSEADDR have been
added to sockbase.s7i. Many thanks go to Domingo Alvarez Duarte
for pointing out that this functionality was missing.
* The function openInetListener in listener.s7i has been improved
to succeed when the socket is reused (it calls setSockOpt with
SO_REUSEADDR now).
* The functions opendir and wopendir in dir_win.c and the function
opendir in dir_dos.c have been improved to check for the maximum
path length supported by Windows and DOS.
* The functions act_string and act_okay have been removed from
actutl.c.
* The function exec_action in exec.c has been improved to use
get_primact instead of act_okay. This results in a significant
performance improvement in the case when WITH_ACTION_CHECK is
defined and the option -tc is used.
* The function str1Split has been removed from strlib.c.
* Documentation comments have been added to arr_rtl.c, arrutl.c,
cmd_unx.c, cmd_win.c, dir_dos.c, dir_rtl.c, dir_win.c, kbd_inf.c,
kbd_poll.c, scanner.c and ut8_rtl.c.
* Interpreter and compiler have been improved to support the action
SOC_SET_OPT_BOOL.
Changes:
* A new numeric escape sequence for string literals has been
introduced. A backslash followed by an integer literal and a
semicolon is interpreted as character with the specified ordinal
number. E.g.: "abc\128;def". With the old numeric escape sequence
this would be "abc\128\def". Terminating the escape sequence
with ; instead of \ improves the readability, especially when
escape sequences follow each other. Instead of "\8\\12\\7\8\9\\\"
it is now possible to write "\8;\12;\7;8\9;\\" The old escape
sequence is still supported, but it is deprecated and should not
be used. Future versions will warn about the deprecated escape
sequence.
* The conversion functions 'bytes' and 'bytes2Int' in bytedata.s7c
have been improved to support all combinations of signedness and
endianess.
* The functions bStriBe and bStriLe have been removed from

source file contains unexpected UTF-8 continuation bytes, solitary
UTF-8 start bytes, extended control codes from the C1 set or an
UTF-16 byte order mark.
* In tar.s7i the functions getoct, putspc and putoct have been
improved. The computation of the size of padding data has also
been improved.
* The compiler has been improved to optimize string initialisations
with the function strZero. StrZero creates a string of arbitrary
length with '\0;' (zero) bytes.
* The compiler has been improved to optimize integer exponentiation
(action INT_POW). Now the multiplication pattern is determined at
compile time and the number of multiplications is reduced.
* The performance of the function setCard in set_rtl.c has been
improved by a factor of 2.5.
* The performance of the function setRand in set_rtl.c has been
improved by a factor of 2.3.
* Loop unrolling inspired by Duff's device has been introduced in
striutl.h. The unrolling is used for tight loops which copy byte
data to Seed7 strings in fil_rtl.c, soc_rtl.c and bst_rtl.c. The
performance improvement has been verified with gcc and valgrind.
* The example program err.sd7, which checks compile time error
messages, has been improved.
* The old way to store the data of constant bigIntegers has been
removed from compiler and runtime library.
* The buffers used in intRadix and intRadixPow2 (file int_rtl.c) have
been enlarged to fit for the most negative number with a base of 2.
* In itflib.c the functions itf_cpy and itf_cpy2 have been fixed to
work correctly, when the destination is converted from a struct to
an interface.

functions prot_char, prot_os_stri, prot_stri_unquoted and
prot_bstri.
* In ut8_rtl.c the function ut8Getc has been improved to use smarter
checks for ranges of characters.
* The deprecated variant of the function str, which has a second
parameter to specify a numeric base, has been removed. The
operators radix and RADIX can be used instead.
* Interpreter and compiler have been improved to support the new
actions INT_BYTES_BE, INT_BYTES_LE, INT_BYTES_BE_2_INT and
INT_BYTES_LE_2_INT. The functions intBytesBe, int_bytesBe,
intBytesLe, int_bytesLe, intBytesBe2Int, int_bytesBe2Int,
intBytesLe2Int and int_bytesLe2Int have been added.
* Support for the actions BIG_CLIT, INT_TO_BSTRI_BE, INT_TO_BSTRI_LE,
INT_BYTES_BE_2_UINT and INT_BYTES_LE_2_UINT has been removed from
interpreter and compiler. The functions bigImport, bigCLit,
big_clit, intToBStriBe, int_toBStriBe, intToBStriLe, int_toBStriLe,
intBytesBe2UInt, int_bytes_be_2_uint, intBytesLe2UInt and
int_bytes_le_2_uint have been removed.
Changes:
* The manual chapter describing the foreign function interface has
been improved.
* The handling of Unicode in the console has been improved. Cursor
positioning and writing Unicode strings to the desired position
works now also under Linux.
* A strict checking of all strings, that are passed to C functions,
has been introduced. Zero bytes and non Unicode characters in the
original string raise the exception RANGE_ERROR now.
* The performance of several loops in the runtime library has been
improved. Now the loops use indices instead of pointer increments
and they work downward towards an index of zero. This allows C
compilers to do more optimizations (verified with gcc and
valgrind).
* The enumeration types signedness and endianess have been added to
bytedata.s7c.
* The conversion functions bytes, bytes2Int and bytes2BigInt have
been added to bytedata.s7c. The new function allow conversions
to and from signed and unsigned byte strings with big- and
little-endian byte order. This functions replace the less flexible
functions bytesLe2Int, bytesBe2Int, bytesLe and bytesBe.
* The functions bStriBe, bStriLe, bStriBe2BigInt and bStriLe2BigInt
have been moved from bytedata.s7c to bstring.s7i.
* The performance of the functions int16AsTwoBytesLe,
int32AsFourBytesLe, int64AsEightBytesLe int16AsTwoBytesBe,
int32AsFourBytesBe and int64AsEightBytesBe has been improved.

int_rtl.c, intlib.c, soc_rtl.c, striutl.c and syvarutl.c.
* The program chk_all.sd7 has been improved to check several
compiler options and to allow that the output of interpreted and
compiled compiler differs. The difference of the generated C code
is okay, when the execution of the compiled programs results in
the same output.

the action BIG_REM (operator rem).
* The compiler has been improved to count inserted and suppressed
range checks.

bigIntegers in bstrings.
* Checks for div, rem, mdiv and mod have been added to chkbig.sd7.
* Checks for float division by zero have been added to chkexc.sd7.
* Checks for float parse have been added to chkflt.sd7.
* In con_inf.c, con_win.c and con_wat.c the function conText has
been replaced by conWrite. ConWrite takes an UTF-32 string and
writes it to the console. If stdout is redirected an UTF-8 string
is written to the destination file.

added to cc_conf.s7i, chkccomp.c, cmd_rtl.c and s7c.sd7.
* Several versions of timAwait in tim_unx.c have been improved to
restart calls of poll(), ppoll() and select().
* A check for the character '=' in the environment variable name has
been added to the function cmdSetenv (in cmd_rtl.c).
* In striutl.c the functions stri_compress, stri_export_utf8 and

condition is constant.
* The compiler has been improved to optimize the action BIG_MDIV
(operator mdiv) correctly, when the divisor is a negated power of
two (e.g. n div -8). The generated code now corresponds to the
Seed7 expression -dividend >> log(-divisor).
* New functions to open files have been introduced in various
libraries. The new functions are openUtf8, openUtf16, openEcho,
openLine, openTee, openMore, openUpper, openLower, openReverse,

(most of) the data used by a program. Several functions, which need
to free program data, have been improved to call prgDestr.
* The functions prgCpy (in prg_comp.c) and prg_cpy (in prglib.c) have
been improve to free a program when the usage_count reaches zero.

and ARR_EXTEND in the interpreter (file arrlit.c) have been
improved to work correctly for arrays with interface elements.
* In blockutl.c the functions free_locobj, free_body, free_block and
free_local_consts have been added or improved.
* In entutl.c the function free_entity has been improved to free also
syobject and name_list.
* The function close_entity has been added to entutl.c. This function
frees the list of inactive entities.

releasing the object, has been added to objutl.c.
* The function free_args has been added to prg_comp.c.
Changes:
* Files to generate man pages for Seed7 interpreter and compiler have
been added to the documentation (files doc/s7.1 and doc/s7c.1).
* The makefiles have been improved to support the targets distclean
and test.
* The operators radix and RADIX have been added to the libraries
integer.s7i and bigint.s7i. This operators convert an integer
respectively bigInteger to a string. The conversion uses the
numeral system with the given base.
* The variants of the function str, which have a second parameter to
specify a numeric base, are deprecated now and will be removed in a
future release. The operators radix and RADIX should be used
instead.
* Interpreter and compiler have been improved to support the
operators radix and RADIX.
* In chkint.sd7 checks for the function str with base have been
replaced with checks for the operators radix and RADIX.
* Usages of the function str with base have been changed to usages
of the operators radix or RADIX in the files gethttp.s7i, bas7.sd7,
encoding.s7i and s7c.sd7.
* Errors in bas7.sd7, concerning the function VARPTR and the
statement OPEN, have been fixed.

programs.
* The currency sign character has been added to stdfont10.s7i,
stdfont12.s7i, stdfont14.s7i, stdfont16.s7i, stdfont18.s7i,
stdfont20.s7i, stdfont24.s7i, vecfont10.s7i and vecfont18.s7i.
* The file chkccomp.c has been improved to define a macro that
describes what happens, when a cast of a float to int overflows.
- This release features the inclusion of the man pages for the seed7
interpreter s7(1) and compiler s7c(1)
- Remove patch included upstream
Changes:
* Interpreter and compiler have been improved to support the option
*l. This option allows adding a directory to the include library
search path (e.g.: -l ../lib).
* The compiler (s7c) has been improved to support the option -b.
With -b the directory of the Seed7 runtime libraries can be
specified (e.g.: -b ../bin).
* The target s7c in the makefiles has been changed to take advantage
of the options -l and -b. Now packages can compile the Seed7
compiler without a post install step.
* Additional function variants of parseFile, parseStri and execute
have been added to the library progs.s7i. The new functions allow
a detailed specification of parse and execution options.
* The library gzip.s7c has been improved to decode also blocks with
fixed Huffman codes. This type of block is almost never used since
dynamic Huffman codes compress better.
* The parsing of bigInteger literals has been improved to support
literals with bases other than 10 (e.g.: 16#FEDCBA98765434210_).
* The integer and bigInteger functions str (conversion to string)
have been changed to use lower case characters for digits larger
than 9. Now str(48879, 16) returns "beef" instead of "BEEF".
* The program make7.sd7 and the library make.s7i have been improved
to support multiple targets and the option -C.
* The Seed7 compiler has been improved to generate special inline
code for the case that the C floating point division by zero does
not result in Infinity, -Infinity or NaN (not a number).
* The functions chkLiteral and chkBitLength as well as checks for
shifts with negative shift count have been added to the program
chkbig.sd7.
* The function check_division as well as has checks for the operator
/:= (in check_nan) have been added to the program chkflt.sd7.
* The function check_str in chkint.sd7 has been improved to check
the new behaviour of the function str with a give base.
* The makefile mk_clang.mak has been added to support compilation
with the clang C compiler.
* The explanations of possible compilation errors in src/read_me.txt
have been improved.
* The functions interpreterPath and callOwnProgram have been removed
from the libraries environment.s7i respectively shell.s7i. This
functions were not used in any example program.
* The support for the interpreter option -m (use less memory during
the analyzing phase) has been removed. On many systems it was a
noop anyway.
* Result variables have been renamed in various libraries and example
programs.
* The functions find_include_file, print_lib_path, append_to_lib_path
and init_lib_path have been moved from infile.c to the new file
libpath.c.
* The function gen_rtl_array has been defined in the new file
arrutl.c. The function is used in the files cmdlib.c (functions
cmd_pipe2, cmd_pty, cmd_start_process) and prglib.c (functions
prg_exec, prg_fil_parse, prg_str_parse).
* The interpreter/compiler improvements (option -l) and the new
function variants in progs.s7i have been realized with changes in
prg_comp.c, analyze.c, data.h, infile.c, infile.h, info.c, option.h
and s7.c.
* The functions prgExec, prgFilParse and prgStrParse in prg_comp.c
have been improved to support additional parse and execution
options.
* The function interpr has been renamed to interpret and moved from
exec.c to prg_comp.c.
* The function copy_args has been moved from prclib.c to prg_comp.c.
* In traceutl.c the function set_trace has been changed and the
function set_trace2 has been removed. The functions mapTraceFlags,
mapTraceFlags2 and set_protfile_name have been added.
* The functions uBigMultiplyAndAdd and bigParseBased have been added
to big_rtl.c:
* In big_gmp.c the functions bigBitLength, bigLShift, bigRShift,
bigLShiftAssign, bigRShiftAssign, bigParse, and bigToInt32 have
been improved and bigParseBased has been added.
* To support bigInteger literals with base the file numlit.c has been

* The Seed7 interpreter was renamed. The new name of the Seed7 interpreter
is s7.
* Manual, FAQ, read_me files and several example programs were updated to
use the new name of the Seed7 interpreter (s7).
