If BASIC were to reinvent itself for the modern era, not as a nostalgia exercise, what would it look like? What niche would it fill? Could it ever be a proper sysadmin tool like it was in the 8 and 16 bit eras? #programming #linux #windows #freebsd #openbsd #sysadmin #basic

My version of "10 PRINT" is now shorter in the operational bit, and like 10x faster because of it, but I still need to count chars and INPUT since there's no "break" key.

Functions Parentheses are optional for 0 arguments, so RND can be treated as a "pseudo-variable", giving a new random number every time it is referenced. ASC(a$) : Unicode value of first character in a$. ATN(r), COS(r), SIN(r), TAN(r) : Arctangent, cosine, sine, tangent of radians r. Use ((d*PI)/180) to convert degrees to radians, (r*180/PI) to convert radians to degrees. ABS(n) : Absolute value of n. CHR$(n) : String containing a Unicode character. EXP(n), LOG(n), SQR(n) : Exponent, natural log, square root of n. Any invalid value like SQR(-1) returns 0. INT(n) : Truncates n to integer portion. LEN(a$) : Length of a string. MID$(a$,i,n) : Substring of a$ from i through i+n-1 indices, starting at 1. Leftmost n characters is MID$(a$,1,n). Rightmost n characters is MID$(a$,(LEN(a$)-n+1),n). PI() : Value of Ο€. RND() : Pseudo-variable, random number from 0.0 to 1.0 (not inclusive) STR$(n) : String of a number. Can also do (""+n). STRCMP(a$, b$): Case-sensitively compares a$ to b$, returns -1 if less than, 0 if equal, 1 if greater than. UCASE$(a$), LCASE$(a$) : Convert string to uppercase, lowercase. VAL(a$) : Numeric value of a string, 0 if not valid. Can also assign to a numeric var. TIMER, DATE$, TIME$ : Pseudo-variables of current time in float seconds since epoch, local date & time in ISO8601, UTC.

Case in point, I'm adding the character-demi-graphics ONLY (no plotting, etc.), like TRS-80 "low-rez graphics".

Fixed a color display bug in terminal, fine.

But the pixel graphics characters can't quite be coerced into filling cells, and are even more off in Chromium, and worse in unsupported Firefox. So I gotta special-case those in rendering.

The web's a hell of a pain in the ass of a medium.

LOAD "testcolor.bas"
LIST
RUN

I don't have energy to make a matrix program but it'd be doable with the tools there. Probably needs a PAUSE command to slow it down to readable, but you could do a busy-wait FOR loop. Currently every redraw of testcolor.bas takes <0.1s.

You can hit ESC to escape the Matrix.

If you replace line 300 with 305, you can get mostly Chinese but also a lot of crap that doesn't render well. I need to make it pick from a few more practical ranges.

(yes, I know my Matriculated Rain looks a little different from the movie thing, but you can't do the streaky effect in chars with 2 "greens").

Something for the #makers of a certain vintage next: NanoBASIC UNO, a BASIC interpreter for the Arduino UNO R3 and other ATmega328P-based microcontroller boards. The weird bit: line numbers are optional, unless you're using them as labels for a jump.

Adding INC & DEC commands, which make pseudo-FOR/NEXT loops a little less hideous,
INC I
instead of
LET I=(I+1)

I just don't feel like dealing with a control stack and all the stupid shit people do breaking out of loops in BASIC.

Gonna finish robots.bas, tho. And maybe do a "graphics" (lo-rez) command or two? MAYBE!

About 2/3 done with a "robots" game in TinyBasicWeb. It's pretty solid, tho I keep filling the Safari console with debug shit and then I have to restart it. Doesn't happen in prod.

I was gonna wait until next year (prob Jan-Mar) to do TinyBasicWeb L2.

But I was in the mood to do some toys that need arrays. "I'll just hack in arrays today!"

Well, yes. But now I need to actually represent expressions instead of *dubious runtime hack*, and it has bit me in the ass.

It's fine. I've got coffee.

You still need something you can write & ship applications in, and BASIC is very terse compared to most languages. A similar program is often half the length of a (more readable) Python or C program.

A VM doesn't help anyone but language implementers.

The down side of BASIC is every dialect is different & opinionated. Maybe that's good, diversity is immunity to viruses & AI slop.

I finally received my PicoCalc yesterday. I’ve installed the included pico and tried out a simple basic program.

Now it’s time to start modifying it. I’m going to upgrade to a Pico 2W, and try out the python firmware.

After that I’m going to try compiling a Rust program for it.
