L1VM - 3.4.0

L1VM (3.4.0)
Changed the -pack bzip2 bytecode compression to bzip3, which generates more compact files.

-- Stefan Pietzonke [email protected] Sat 22 Mar 2025 21:38 +010

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".

L1VM - 3.3.7

L1VM (3.3.7)
VM/MPFR module Windows and macOS build scripts: memory bounds added.

-- Stefan Pietzonke [email protected] Fri 21 Feb 2025 32:00 +010

L1VM - 3.3.6

Added "repair multi spaces" function to compiler.
It fixes the two or more spaces problem between tokens.

    (set  string  13 hello   "Hello world!")

will be changed to:

(set string 13 hello "Hello world!")

   For the other changes see ChangeLog!

L1VM - 3.1.5

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 [email protected] Tue 21 May 2024 15:57 +020

For older changes see ChangeLog!

L1VM - 3.1.0

NEW: now math expressions can be written like this in Brackets:

{i = xd + yd}

The () brackets are not longer needed for this, to work.
The old way was:

{i = (xd + yd)}

-- Stefan Pietzonke [email protected] Thur 1 Feb 2024 21:18 +0100

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

L1VM (2.8.7)
Added SDL GUI module set_gadget_menu, see: "lib/sdl-lib-test-menu.l1com"!

-- Stefan Pietzonke [email protected] Thu 18 Jan 2024 22:53 +0100

L1VM (2.8.6)
The preprocessor now removes empty .md documentation files.

-- Stefan Pietzonke [email protected] Son 31 Dec 2023 15:18 +0100

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

-- Stefan Pietzonke [email protected] 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.

Added crypto module key hashing and testing functions.
Added crypto module single key generation via password.

-- Stefan Pietzonke [email protected] Mon 18 Dec 2023 18:33 +0100

L1VM (2.8.1)
VM: added "-fPIE" flag to RELRO zerobuild scripts.

-- Stefan Pietzonke [email protected] 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 [email protected] 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 [email protected] 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 [email protected] 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 [email protected] 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 [email protected] Mon 23 Oct 2023 20:56 +0200

This is the L1VM 2.4.2 release with official Haiku OS support.

ChangeLog:

L1VM (2.4.2)
NEW: This version has the working Haiku installer scripts.
So Haiku OS is now official supported.

-- Stefan Pietzonke [email protected] Fri 7 Jul 2023 17:09 +0200

L1VM (2.4.1)
BUHFIX: The compiler now checks if a variable was already defined at "set".
So this will result in an error!

BUGFIX: now the infix/RPN parser works again! Sorry for this!

Added "install-zerobuild-openbsd.sh" experimental install script for OpenBSD.
Added VM range check now prints out variable value and min max values.

Set STACKSIZE in include/global.h to 4096 bytes. Should be enough!

NEW: VM "get_size" interrupt 33 pointer variable to get the variable size in bytes.
NEW: added "print_lni", "print_lnd" and "print_lns" macros int "intr.l1h" to print variables with a new line at the end.
NEW: l1pre now has multiline @@ line split chars.

NEW: Haiku port: RS232 module now uses Haiku RS232 port names too!

I did also build the FANN library and copied it into the Haiku libs folder.
You have to download the FANN library source code.
Then you need to configure it:

$ cmake . -DCMAKE_INSTALL_PREFIX=/boot/home/config/non-packaged
$ make install

Now you can build the L1VM FANN module.
NEW: now code and data are erased before freeing the RAM.

Debian install scripts now use clang-15 package for install and build.

L1VM (2.3.0)
NEW: compiler: type check in infix/RPN parser (parse-rpolish.c). If types of int and double are mixed then it results in a compile error!
Also gives an error if the variable inside a math expression is an array!

NEW: checks on variable to array and array to variable: make sure variable type is not array on assign:

(array tarray [ index ] =) -> error
(tarray [ index ] array =) -> error

Preprocessor now gives error message if #include is with quotes " ", instead of < >.
So if not an Brackets source code file is compiled, you get an error message!

Added checks if source code line has brackets or not. Give a compiler error if no brackets are found in line.
So the Brackets compiler now does not crash any mor on non Brackets source code files!

BUGFIX: file/open did not set file open flag.
BUGFIXES: ciphersaber module now works!

NEW: now the l1vm-build.sh script searches for includes in the current folder too!

NEW: scripts in distribution now use "bash" as the shell, this fixes some errors!

FIXES: compiler now gives error if label is defined twice. And if function name already used.

Compiler: update: now "stpop" opcode to loadreg code part set.
Added script to build and install latest Clang from GitHub.

NEW: prog/bool.l1com include/bool.l1h : define variable true/false.

Now boolean variable assign is checked by the "bool" command:

(bool true Bool =)

Only "true" or "false" are allowed in this expression!
Here the variable "Bool" will be set to "true".

Compiler:
NEW: new "bool" variable type in "set" variable setting.
The bool variable name must begin with a uppercase "B"!

// boolean variable name must beginn with upercase B!
(set bool 1 Bool 1)

The parser checks if the boolean variable is used in a normal math expression and returns an error if so!
This also includes the RPN parser and the infix expression parser.

NEW: more mono fonts added. Moved standard free mono font into /free.

NEW: now you just can do:
(true Bool =)
to set a boolean variable!
