New Regex Syntax. Some of the escaping is different but should do the same.

What percentage to you get with RC18 when running the regex test? I only get 67.7%

V6.01.00RC19

PicoMiteV6.01.00RC19.zip

Fixes bug in reading data into a buffer in mode 1 on high res screens (fixes turtle bug)

Includes the complete new regular expression engine in all versions. See second post here for the supported syntax.

Peter,

Just spend hours testing rc18. Looking good. Lost 16384 bytes size on A:/drive in 2040 non-VGA. This can be managed by Game*Mite. Please don't take off more from A:/.

I hope rc19 is not much different. The 'reg-ex' is that only in WebMite, or in all pico's ?

I still get only a 67.7% passing rate in the test suite.

matherp said What version?

RC19. I'm using the regex test you posted here although I had to repair one HTML tag line that was broken.

' ============================================================================
' Test 16: Real-world examples
' ============================================================================
Print "--- Real-World Examples ---"
RunTest("IP address", "192.168.1.1", "\d+\.\d+\.\d+\.\d+", 1, 11)
RunTest("HTML tag", "
content
", "<\w+>", 1, 5)
RunTest("Currency", "$123.45", "\$\d+\.\d+", 1, 7)
RunTest("Time format", "Time: 14:30:00", "\d+:\d+:\d+", 7, 8)

Fix from the CMM2 thread:

' ============================================================================
' Test 16: Real-world examples
' ============================================================================
Print "--- Real-World Examples ---"
RunTest("IP address", "192.168.1.1", "\d+\.\d+\.\d+\.\d+", 1, 11)
RunTest("HTML tag", "<div>content</div>", "<\w+>", 1, 5)
RunTest("Currency", "$123.45", "\$\d+\.\d+", 1, 7)
RunTest("Time format", "Time: 14:30:00", "\d+:\d+:\d+", 7, 8)

What version means VGA, HDMI, RP2040, etc. You shouldn't have to repair anything. Is this your PicoCalc build? Have you modified cmake to pick up the new engine. There are no errors if built correctly.

PicoCalc build. What mods need to be made? I only changed CMakeLists.txt to compile the PICORP2350 version. What else must I do? I didn't see anything on UKTailwind's website.

CMakeLists.txt specifies which files to build into the image. If you haven't updated as per the github you are still compiling with the old regex engine. Delete regex.c, regeex.h and xregex.h from your build environment. If it then doesn't build you know CMakeLists.txt is wrong. If you are mirroring https://github.com/UKTailwind/PicoMiteAllVersions you need to do it accurately

I used the CMakeLists.txt right from Github, only changing the target system to PICORP2350. Those three files you mention aren't in the PicoMiteAllVersions directory at all.

I can confirm first hand that the PicoMite v6.01.00RC19 files at GitHub are correct and self-consistent. I picked them up this morning and added the MMDebug hooks to them. And they compiled clean.

(Just one minor warning about cccq2nqu.s:16461: Warning: ignoring changed section attributes for .text)

Are you compiling on Windows? If so, my build .BAT file might help you get out of the woods???

I use the Linux subsystem in Windows. Are there instructions somewhere for using Windows directly? The only instructions I can find use Linux.

Actually... Originally, I was going to use the Linux subsystem for Windows to build it. But I ran into a lot of problems doing that. It was easier to just setup the build environment directly in Windows.

How about we take this off-line and not clutter up this thread? I'll send you a cheat sheet with what I did to get a compliant and stable build environment along with all the URL's and stuff to get the tools. (The cheat sheet is for me so I can 'easily' retrace my steps if I need to setup the build environment on another machine in the future. If a particular step doesn't make sense, you can just send me an email and I'll try to help you over whatever hurdle is in front of you.)

Harm

Please can you give this a quick test on the Game*Mite. I hope you have got a bit of disk back and it still works. Might even be a tad quicker - let me know

Olimex RP2350pc

I don't know if this question belongs here.

Is the olimex rp2350pc a suitable device as a picomite computer?

The audio codec isn't supported. Audio output will be PWM only, on PWM5A and PWM5B. Line input isn't supported at all.
HDMI video looks like it works if you set the pins correctly. You might have fun setting it up though as there's no default console on GP8 and GP9. You would need to set one up using a USB-TTL adapter on GP0 and GP1 or GP38 and GP39 by typing blind.
PSRAM is using GP8 for select.

Otherwise I *think* it will work. It's just a case of sorting out the OPTION settings needed after that.
