ChangeLog

L1VM (3.6.0)
	VM: experimental "main-sched.c" virtual CPU task scheduler added.
	See prog: "hello-sched.l1com".

	I fixed a bug in the L1VM scheduler POSIX threading code start position.
	NOTE: you can't start new POSIX threads in the L1VM scheduler VM.
	I try to fix this, but it can take some time.

L1VM (3.5.6)
	Note: I did run Cppcheck and Infer on "l1vm", there were no errors found.

	VM: added cbmc.sh CBMC code check tool, with mathematical proofs. The L1VM core has no errors. Only the string functions don't pass the tests. This means that they can not be proven to be correct. But they are safe! This is important to know!

	Added Brackets code formatter in "formatter" directory.

	New flag: (varname-ascii) if set only alphanumerical chars and "_" in variable name allowed!

	VM: Optimized memory bounds check. Now a lot faster using & instead of modulo.
	VM: added msg module to send receive messages. See "messages-mod.l1com".

	VM: msg module: added allocating max messages and string messages via calloc().

	Compiler: now rbuf and rbuf_orig are global to show line and linenumber in var.c error messages.
	Linter: checks now if in a function with return arguments, (return) was used.

-- Stefan Pietzonke <info@midnight-coding.de> Sat 21 March 2026 20:55 +020

L1VM (3.5.5)
	The linter has now a "strict" flag. With it set the result variables must end by a uppercase "R" ending.
	They are not alowed as function arguments. See "linter/math-inc-strict.l1com".

	Now the function call variables are also checked and can't be used after the function call.
	And pointers to the variables can't be used too.

	NEW in linter:
	// (remove foo)

        Marks variable foo as invalid. It can't be used again after this line!

        NEW Linter flags to check if pointer variable is of type "const-int64":
	// (pointer strict on)
        // (pointer_strict_off)

-- Stefan Pietzonke <info@midnight-coding.de> Fri 09 January 2026 21:55 +010

L1VM (3.5.4)

	VM: Added gps module to read GPS from the gpsd server.
	See "lib/gps.l1com" example.

	NEW: The linter has now a "strict" flag. With it set the result variables must end by a uppercase "R" ending.
	They are not alowed as function arguments. See "linter/math-inc-strict.l1com".

	Added VM/string: "string_format_num" function to print strings formatted: 1,000,000.12345.

-- Stefan Pietzonke <info@midnight-coding.de> Sun 27 December 2025 18:26 +010

L1VM (3.5.3)
	VM: added L1VM embedded functions to read/write to global data array.
	VM: rs232 library: added Windows build script.

	The installer scripts are now in "install" directory. And the program build scripts are now in "scripts".
	I did clean this up.

-- Stefan Pietzonke <info@midnight-coding.de> Wed 20 August 2025 22:34 +020

L1VM (3.5.2)
	Example programs updates.

-- Stefan Pietzonke <info@midnight-coding.de> Sun 17 August 2025 14:00 +020

L1VM (3.5.1)
	Compiler: NEW flag  -savecode to put the Brackets code line into the assembly output.

	VM: modules: I added support for Bluetooth BLE with the SimpleBLE library.
	Note: If you use the SimpleBLE library commercially, then you have to pay a license!

	I did check the Bluetooth BLE read and write functions. They both are working!
	NEW: support for NetBSD and also MidnightBSD.

-- Stefan Pietzonke <info@midnight-coding.de> Thu 07 August 2025 20:37 +020

L1VM (3.5.0)
	Compiler, assembler MAXLINELEN fixes.
	AsmJIT compiler finally updated to the current GitHub version.

	NEW: SDL 3.0 module: gfx primitives like lines, pixel and GUI are working.
	I added camera support. See in "prog/sdl" example.

-- Stefan Pietzonke <info@midnight-coding.de> Sat 31 May 2025 17:54  +020

L1VM (3.4.2)
	In settings header LOW RAM limits changed.
	The compiler needs then only 11 MiB to compile.
	Compiler fixes.

	NEW: now in Brackets code a new flag "(linter)" can be set to make sure the code was "linted"!

	NEW: added contracts into the compiler. Now "preconditions" and "postconditions" can be set in a function.
	See example "prog/lint/math-inc.l1com"!

-- Stefan Pietzonke <info@midnight-coding.de> Thu 08 May 2025 18:12  +020

L1VM (3.4.1)
	Added new string-unicode module for unicode support.

L1VM (3.3.8)
	Preprocesso: show line number in macro errors.
	Preprocessor: second pass removed. Now error messages show the right line numbers!

	VM: added two new interrupts to switch memory bounds check on push/pull opcodes:

	(:memory_bounds_off !)
	(:memory_bounds_on !)

	If it is switched off then the execution speed can increase a lot.
	But the overflow checking is disabled for push/pull opcodes!

	Added "unsafe" and "unsafe-end" code blocks.
	Inside a unsafe block the memory bounds checking can set on/off.
	See example "prog/little-vm.l1com".

	Added variable prefixes:

	(\num\x * \num\y \num\z :=)

	So here is the prefix: \num\
	All variables must have the same prefix like the target variable \num\z.
	So here \num\ is a special type all variables in the math expression must have.
	See "prog/type.l1com".

-- Stefan Pietzonke <info@midnight-coding.de> Sat 08 Mar 2025 12:57  +010

        (set  string  13 hello   "Hello world!")

	will be changed to:

	(set string 13 hello "Hello world!")

-- Stefan Pietzonke <info@midnight-coding.de> Sat 08 Feb 2025 13:44  +010

L1VM (3.3.5)
	VM: MPFR module: print number string fixes. Now the function checks if string is big enough before saving it into the temp file.

	New build scripts with "wspace" in the name. They warn if there are more than one space between tokens.
	Use them to find such errors where the preprocressor just gives an error message without line number!

-- Stefan Pietzonke <info@midnight-coding.de> Sun 22 Dec 2024 23:46  +010

L1VM (3.3.4)
	VM: string module: added string_verify function to check if a string contains valid chars.

-- Stefan Pietzonke <info@midnight-coding.de> Thu 14 Nov 2024 21:30  +010

L1VM (3.3.2)
	VM: MPFR module now uses nano ID for temp file name".
	VM: -q flag also silences the threading interrupt functions!

-- Stefan Pietzonke <info@midnight-coding.de> Sun 10 Nov 2024 21:26  +010

L1VM (3.3.1)
	VM: net module now has experimental SSL support.
	For a demo see "lib/ssl" directory examples.
	There is a README to explain how to use it.
	I found a SSL tutorial and modified it to make it fit with the other net module code.
	On a SSL connection you can use the normal socket read/write functions.
	It automatically selects the right functions.

	This is a bugfix release. The line number output code was removed.
	The pov-edit program now works again!

-- Stefan Pietzonke <info@midnight-coding.de> Tue 22 Oct 2024 22:21   +020

-- Stefan Pietzonke <info@midnight-coding.de> Thu 19 Sep 2024 16:26  +020

L1VM (3.2.1)
	Compiler bugfixes: now a expression like:

	 (((x y +) ret :=) ret2 :=)

	Is parsed without error! It is assining ret and ret2 to the result.

	NEW: Added bytecode hot reload feature. See "prog/reload" for a demo program.
	The data is unchanged and must be all at the same addresses in the new loaded bytecode.
	Only the code can be changed!

-- Stefan Pietzonke <info@midnight-coding.de> Tue 10 Sep 2024 17:39  +020

L1VM (3.2.0)
	Preprocessor bugfixes. Now the preprocessor can insert the string_immutable interrupt on "const-string" variables.
	So they can be checked then for overflows.

	The preprocessor now can insert the "for" loop start line "(for-loop)" automatically.
	See "prog/hello-for-3.l1com" example.

	The preprocessor now warns if the intr0 and intr1 interrupts are used direct in the program.
	They should be used with the macros in "intr.l1h" or "intr-func.l1h".

-- Stefan Pietzonke <info@midnight-coding.de> Sat 07 Sep 2024 14.16  +020

L1VM (3.1.12)
	NEW: interrupts for allocating function local data by copy all data to local

	See prog/webserver-thread-local-2

-- Stefan Pietzonke <info@midnight-coding.de> Sun 25 Aug 2024 09:49  +020

L1VM (3.1.11)
	NEW: the preprocessor can now check the variable types set in the macros.

>> intr-func.l1h
>> interrupt macros - new only functions - no macros
>> intr0
>> @# chars to print \n newline char
>> new: types can be set by setting the variable types as the first char:
>> i = integer / string pointer
>> d = double
>> s = string
>> iFOO -> set iFOO as an integer variable
>>

-- Stefan Pietzonke <info@midnight-coding.de> Wed 14 Aug 2024 16:29  +020

L1VM (3.1.10)
	VM/mpfr module: I did set a new flag in settings.h to set the MPFR modules filesize function call:

	// Set this to 1 if you are using clang 15 or older.
	// If you are using clang 16 or later then set this to 0
	// This sets the type of the MPFR filesize function. If it is the experimental function or not.
	#define CPP_FILE_EXPERIMENTAL 1

-- Stefan Pietzonke <info@midnight-coding.de> Wed 07 Aug 2024 16:49  +020

        Assembler: now checks for l1vm home directory for file loading in byte variable.

	Compiler: now gives error if "call" or "!" is missing on a function call like this:

	(x y :foobar)

	VM: MPFR module: use latest version of the mpreal.h include from GitHub repo.

	Assembler: load file into byte/string variable filename check for ../ added.
	It is illegal! You can only access file in "~/l1vm" L1VM home directory.

-- Stefan Pietzonke <info@midnight-coding.de> Wed 03 Jul 2024 18:44  +020

L1VM (3.1.7)
	NEW: VM can be build as a shared library for embedding it in other programs.
	See vm/README!

-- Stefan Pietzonke <info@midnight-coding.de> Tue 28 May 2024 22:30  +020

L1VM (3.1.6)
	VM: new interrupts 0: 35/36 to get host CPU and host OS type.

-- Stefan Pietzonke <info@midnight-coding.de> Sat 25 May 2024 17:10  +020

L1VM (3.1.5)
	Compiler: added := as assign operator for expressions too.
	So you now should use := as the assign operator for new programs.
	The old way of using = still works. This is backwards compatible
	and older programs still compile.

-- Stefan Pietzonke <info@midnight-coding.de> Tue 21 May 2024 15:57  +020

L1VM (3.1.4)
	NetBSD: changed the order of allocations in main().
	Added preprocessor blocks to run the "run(0)" function.
	The pthread_create () call crashes on NetBSD. So there is no multithreading possible yet!
	If you know how tom fix this, then contact me please!

	Compiler: now you can write expressions like this:

	(xd * yd zd :=)

	With the target variable on the right side.

	In did add "include/intr-func.l1h" to use functions only.
	This is needed to use the new "(:print_n !)" syntax.
	The old "intr.l1h" is still there for the older syntax using programs.

	I did add checks to avoid usign stpop on a constant variable.

-- Stefan Pietzonke <info@midnight-coding.de> Sun 19 May 2024 15:35  +020

L1VM (3.1.3)
	Added nanoid module for generating unique IDs.
	See lib/nanoid.l1com.

-- Stefan Pietzonke <info@midnight-coding.de> Sun 12 May 2024 07:36  +020

L1VM (3.1.2)
	NEW: now preprocessor macros can be called like function calls:

	// print string
	(hello :print_s !)
	print_n

	See "prog/hello-func.l1com" !

-- Stefan Pietzonke <info@midnight-coding.de> Wed 08 May 2024 23:37  +020

L1VM (3.1.1)
	NEW: linter now checks if function call: "call" or "!" have a space in front or not.
	MPFR C++ math library added checks to set number functions: now they check if the new number string is a number!

L1VM (3.0.9)
	NEW: Added thread local data memory erasing before free the data.

-- Stefan Pietzonke <info@midnight-coding.de> Sat 23 Mar 2024 18:56  +010

L1VM (3.0.8)
	I did add a linter for checking of function call arguments.
	See prog/lint directory! The build script is: "l1vm-build-lint.sh".

-- Stefan Pietzonke <info@midnight-coding.de> Fri 22 Mar 2024 12:54  +010

1VM (3.0.7)
	I did add a new interrupt to set strings as immutable:

	(set string s worldstr " world!")

	// set string as immutable:
	string_immutable (worldstr)

	See "intr.l1h"!

-- Stefan Pietzonke <info@midnight-coding.de> Tue 19 Mar 2024 22:00  +010


L1VM (3.0.6)
	AsmJit library si now included in the L1VM sources.
	I did clean up the JIT-compilers directories.
-- Stefan Pietzonke <info@midnight-coding.de> Tue 12 Mar 2024 17:27  +010

L1VM (3.0.5)
	NEW: functions with no side effects can be marked as "pure".
	A pure function can only call other "pure" functions.
	See prog/hello-pure.l1com.

	Here is an example function:

	(squareP func)
	    #var ~ squareP
	    (set double 1 num~ 0.0)
	    (set double 1 ret~ 0.0)
	    (num~ stpopd)
	    {ret~ = num~ * num~}
	    (ret~ stpushd)
	(funcend)

	This function depends only on the given argument number and returns the square of the number.
	So it is "pure"!

-- Stefan Pietzonke <info@midnight-coding.de> Thu 07 Mar 2024 06:57  +010

L1VM (3.0.4)
	Should work:
	addi, subi, muli, divi

	eqd, neqd, grd, lsd, greqd, lseqd

-- Stefan Pietzonke <info@midnight-coding.de> Mon 04 Mar 2024 16:52  +010

L1VM (3.0.3)
	ARM JIT compiler: first steps are done!
	Should work:
	addi, subi, muli, divi
	addd, subd, muld, divd

	There is still lot work to do.

-- Stefan Pietzonke <info@midnight-coding.de> Tue 27 Feb 2024 19:48  +010

L1VM (3.0.2)
	BUGFIXES in modules and other parts.
	NEW: "variable-local-only-on" and "variable-local-only-off" compiler flags to allow only local variables and no main global ones.

	{i = (xd + yd)}

-- Stefan Pietzonke <jay-t@gmx.net> Thur 1 Feb 2024 21:18  +0100

L1VM (2.9.0)
	Added "return" to compiler. See "prog/return.l1com".

-- Stefan Pietzonke <jay-t@gmx.net> Thur 1 Feb 2024 15:54  +0100

L1VM (2.8.8)
	NEW: Added "tab" to SDL multiline string gadget. With the "tab" key you can insert spaces to "wrap" to the next input line.
	See program "lib/sdl-lib-test.l1com".

-- Stefan Pietzonke <jay-t@gmx.net> Sun 28 Jan 2024 20:05  +0100

	Added net module read/write byte arrays

-- Stefan Pietzonke <jay-t@gmx.net> Son 31 Dec 2023 15:18  +0100

L1VM (2.8.3)
	Added l1vmgodata links between keys added.
	See l1vmgodata on GitHub.

-- Stefan Pietzonke <jay-t@gmx.net> Sat 23 Dec 2023 18:49 +0100

L1VM (2.8.2)
	l1pre preprocessor:
	Added:

	#docustart
	#docuend

	You can write documentation inside this two flags.
	The preprocessor outputs this into "out.md" Markdown file.
	See "prog/math-circle-bignum" for an example.

	Added crypto module public/private keys generation and encryption/decryption.

	BUGFIX: compiler line: main.c 1786 and following: variable to array assign code fixes.

	VM: added "-fPIE" flag to RELRO zerobuild scripts.

-- Stefan Pietzonke <jay-t@gmx.net> Mon 27 Nov 2023 19:10 +0100

L1VM (2.8.0)
	Now I did change the way how local and global variables are used.
	I did add two new compiler flags:

	(variable-local-on)
        (variable-local-off)

	If the flag is set to one then only the current function local variables and the main function global variables can be accessed.
	You need to use this in your main function:

	#var ~ main

	So all variables in main are set with the "main" ending:

	(set int64 1 foo~ 12)

	This variable would be named "foomain".
	If you want to see an example then have a look at: "prog/math-circle-bignum-2.l1com".

	UPDATE: string module: all MAXLINELEN now replaced by MAXSTRLEN!

	NEW: I did add a experimental install script for NetBSD. It may not work at all.
	I need to test it on my NetBSD installation.

-- Stefan Pietzonke <jay-t@gmx.net> Sat 18 Nov 2023 18:06 +0100

L1VM (2.7.3)
	Update: now the network module uses a read/write buffer on the file send function.
	This gives a very high speedup!

-- Stefan Pietzonke <jay-t@gmx.net> Sun 12 Nov 2023 17:40 +0100

L1VM (2.7.2)
	I did set a maximum source code line length tp 512 chars.
	The default settimng was 4096 and this was way to high for programs with a lot of lines.

	Update: now the network module uses a read/write buffer on the file send function.
	This gives a very high speedup!

-- Stefan Pietzonke <jay-t@gmx.net> Fri 10 Nov 2023 17:09 +0100

L1VM (2.7.1)
	NEW: MPFR module: mp_set_float_prec function to set numbers base and precision (internal bits).
	So you can calculate with real big numbers.
	See prog/primes-bignum.l1com.

-- Stefan Pietzonke <jay-t@gmx.net> Mon 06 Nov 2023 19:51 +0100

L1VM (2.7.0)
	I did change the way how the global data is used.
	It is now possible to allocate local data in a thread.
	The "data_local_alloc" interrupt allocates local memory and copies the whole global data in it.
	So all data accesses in the thread are local. As long as you don't switch to global data.
	See "prog/hello-thread-3-local.l1com" and "prog/webserver-thread-local.l1com".

-- Stefan Pietzonke <jay-t@gmx.net> Mon 23 Oct 2023 20:56 +0200

L1vM (2.6.7)
	Update: memory module init code fixes.

-- Stefan Pietzonke <jay-t@gmx.net> Sat 20 Oct 2023 23:00 +0200

	After a successfull installation you can try the new "start.l1com" SDL demo launcher:
	$ l1vm start

	The start menu should be shown in a small window.
	Have some fun!

	NEW: VM now prints execution pos on errors. The assembler generates now a *.l1dbg text file
	with the epos and assembly line number for easy error finding.

	Now a stack check flag in "global.h" can be set for stack variable type checking on runtime.
	Note: some programs may fail with an error!

	NEW: home directory name now is get by HOME env variable (getenv).

L1VM - (0.9.11)
New: serial port library "rs232-libserial" using libserialport.
I included a new library: "lib/rs232-lib-libserialport.l1com" for using libserialport for RS232 port.

VM: Code size and data size are now shown as for example "KB".
VM: max number of CPU cores can now be set via command line flag:

$ l1vm prog/hello-2 -C 1

Sets the max CPU cores to 1 core.

New: VM: memory_bounds () now gives an exception if the offset_access is not on variable memory bounds.
So now every illegal access gives an exception if memory bounds check is active.

L1VM - (0.9.10)
New: global.h include: MATH_LIMITS define, sets if integer math overflow is handled
by an exception or not.
See prog/math-overflow.

New: math overflow detection on double floating point numbers. See include/global.h!
Interrupt intr0: 251 check double floating point number for overflow. And set the flag for it.
Interrupt intr0: 252 returns overflow flag.
New: global.h include: MATH_LIMITS_DOUBLE_FULL sets double number calculation arguments check.
If it is 0 then only the results of calculations are checked. This is a bit faster.

Removed the GMP library and replaced it with more modern MPFR via MPFR C++ wrapper!
New: MPFR big number calculation library: float numbers: add, sub, mul, div, print and prints (formatted output).
See vm/modules/mpfr-c++ and lib/mpfr-lib.l1com.
I already wrote some wrapper for trigonometry functions. More functions will come later...

New: MPFR library: constant functions added for pi, log2, euler and catalan.
See lib/mpfr-lib-auto.l1com.

MPFR library: mp_prints_float: write output to file like in mp_print_float, and read in string.

Time module: datetostring: month fixed leading zero on month < 10.

New: vm/modules/rs232: poll comport now reads data into given data pointer.

New: string library: string_compare to compare two strings.

L1VM - (0.9.9)
New: if and if+ optimization in bracket compiler added:
just add this line into your bracket program:

(optimize-if)

This leaves out some instructions in the assembly output, resulting in a speedup.

New: Added clang toolchain in: clang-8.0.1. Just use the bash script there.
It downloads, compiles and installs clang to your /home directory in: l1vm-clang.
There is no root right needed to install!
The makefiles are copied at the script end.

New: added run time sense check into the VM for S8 and F8 variable types to be 64 bit big.
It will stop the VM if something was broken during compilation.

New: process-lib in libs directory: for running processes via system call.

New: assembler now shows the size of the created obj. file.

New: compiler stops if undefined labels are found.

New: OSV capstan build directory: build L1VM for OSV unikernel.
New: VM: INTR0 and INTR1 default switch is to print error message if interrupt number is not right.
New: VM shows the used C compiler and version number.
New: SANDBOX file root access in /home directory.

L1VM - (0.9.8)
New: if+, else, endif in compiler l1com.
So finally here is "else" in "if+". :)

New: do/while loops! See prog/hello-while.l1com.
New: for/next loops! See prog/hello-for.l1com.

New: vm/main.c removed MEMCHECK, now all memory access checks are done by memory_bounds() function.

The header vor object code files changed to the more friendly:
C0DEBABE00002019

So in order to run older programs you have to recompile them!

New: two scripts in prog/ directory:
compile.sh to compile and assemble programs:
$ ./compile.sh foobar

And "build-all.sh" to compile and assemble all programs in prog/ directory.
Bugfix: memory_bounds memory access checker now should work!

-- Stefan Pietzonke <jay-t@gmx.net>  Tue Aug 6 2019 11:35 +0200


L1VM - (0.9.7)
New: check if variable is array on array access assign.
New: compiler now prints error message if used variables are not defined.

Added VM quiet mode: "-q" bash flag, if set no startup messages are shown.
See "silent_run" runtime flag.

Bugfix: compiler array size check now uses int64 for sizes!
New: prog/primes.l1com - Sieve of Eratosthenes prime number search.

New: assembler: "-pack" flag: creates bz2 compressed object:
$ l1asm foobar -pack
creates a "foobar.l1obj.bz2" packed object file.
The VM detects a .bz2 object code and decompress it before execution.

New: prog/primes-3.3.l1asm, hand optimized assembly for primenum search.
Runs a bit faster as primes-3.l1com program.

vm/main.c: stpop(i/d) better bound checks on stack pointer.

vm/modules/string cleanup. Now compiles and runs right.
This was tested by the string library and it works!

String code cleanup: "strlen_safe" function added to other "string.c" files.

-- Stefan Pietzonke <jay-t@gmx.net>  Sun Jun 30 2019 17:38 +0200


L1VM - (0.9.6)
New: threaddata now allocated by calloc() in main.c, main().
VM: MAXCPUCORES now prints error message on compile if it is "0"!
Updated README.md nd vm/modules/genann/README.md.

NEW
===
Added array variable assign for int64 and double array variables:
prog/array-int64.l1com and prog/array-double.l1com!

Added array support for the other variable types too!

Now assembler and compiler show version number 0.9.6 too!

NEW: array variable bounds check. See global.h: BOUNDSCHECK definition.
This checks every data access at runtime if SET to defined.

-- Stefan Pietzonke <jay-t@gmx.net>  Tue Jun 11 2019 19:24 +0200


L1VM - (0.9.5)
New: Assembler: max code and data sizes can be set via shell flag:
$ assemb/l1asm prog/hello-2.3 -sizes 40000 60000000

This sets the max code size to "40000" bytes and the max data size to "60000000" bytes.
Removed unused variables.
Added "-Wall" to zerobuild makefiles.
Cleaned up "global.h", user settings in one place at top!

assemb/checkd.c: get_temp_int() and get_temp_double() now show linenum and string on ERROR.
New: compiler can be called with "-lines" flag to set max number of source code lines:
$ l1com foobar -lines 40000

Compiler: added cleanup function.

-- Stefan Pietzonke <jay-t@gmx.net>  Thu May 23 2019 06:30 +0200


L1VM - (0.9.4)
New: data file can be loaded into byte variable array. See "prog/hello-2.3.l1com" for example code.
Example data declaration:
(set byte 40000 data_file $/home/stefan/l1vm-0.9.4/prog/hello.l1obj)
C compiler warning in VM fixed: "#define _GNU_SOURCE 1" in global.h set if not defined.

-- Stefan Pietzonke <jay-t@gmx.net>  Fri  May 17 2019 16:00 +0200


L1VM - (0.9.3)
New: file library uses S8 as handle type.
New: translate.h now uses "d" to use double floating point opcodes:
