Re: [fricas-devel] Struggling with OutputForm
Hello, I looked more carefully at your suggestion, and, yes, 'pile' is very interesting for my purpose, but only in Format2D from what I have seen. Moreover it's not as simple as I like to switch to it, I didn't even know how. In algebra output "mode", look at this if I use the '=' operator. Apparently in algebra mode 'pile' piles everythings: (1) -> a:=qnew(4,4)$JF64MAT;a=a (1) 0.0 0.0 0.0 0.0 = 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.00.0 0.0 0.0 0.0 0.0 0.0 0.0 0.00.0 0.0 0.0 0.0 0.0 0.0 0.0 0.00.0 0.0 0.0 0.0 (2) -> juliaMPrint(false)$JF64MAT (2) true (3) -> a=a +0.0 0.0 0.0 0.0+ +0.0 0.0 0.0 0.0+ |0.0 0.0 0.0 0.0| = |0.0 0.0 0.0 0.0| (3) |0.0 0.0 0.0 0.0|0.0 0.0 0.0 0.0| +0.0 0.0 0.0 0.0+ +0.0 0.0 0.0 0.0+ (4) -> )lib JF64MAT JuliaFloat64Matrix is now explicitly exposed in frame frame1 JuliaFloat64Matrix will be automatically loaded when needed from /home/greg/Git/jlfricas/JF64MAT.NRLIB/JF64MAT (4) -> a=a (4) 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 = 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 %%(1) is with 'vconcat' and algebra mode, %%(2) the FriCAS mode, i.e. using matrix$OutputForm, %%(3), an equation, %%(4) the same with 'pile'.

But the code is almost done, it was the first time I used AI generated code. By inadvertence Copilot gave me a piece of AI generated Julia code, even better than what I was finding about redirecting IO etc. I also asked if it can code in FriCAS Spad, and after a topo on FriCAS and Spad, it responded yes, I just had to fix it, FriCAS from my voice is interpreted as fricassée ;). Not as good as Julia but that's a beginning. I asked it to code a factorial function, it gave me a FACTORIAL domain with factorial in it. The future is already here. Highly based on your github.io work from what I have seen ;) To come back to this discussion, I really need a string representation to conform to FriCAS "conventions, and I do not like using Julia to print something on the terminal, I was doing that. Moreover I have added some times ago some code to use the PCRE library so I can catch a regular expression, do some replacements, etc. So having a string is very important to me to output it.

It could be of use to me, yes. I am recording it it!
It requires switching off algebra though, and frankly I really like the
work done by the Julia community for outputting their objects.
No plain text mail, sorry.

Personally, omitting the place of displayed type, time, memory usage and so
on, I prefer "data'' line cutted by the console. I am even asking myself
now if the underlying CL system does not have a way to interact with the
console for its parameters. More to look at. But, I "struggled" too much
with this, understanding the functions flows in outputting FriCAS objects,
I even loved the function 'name concatTrouble'. I'm not a big fan of coding
aesthetic things like this. Readability is also important of course and the
first time I tried Axiom, I was astonished by its 2D printing, do not take
my critics wrong.
I did not know your way of printing, I tried yesterday the formatted output
but had no output, I better understand now. The output is still buggy since
the output is no longer saved by the system command )spool, it's a pity.
There are rooms of work to do. One is using at Spad level I think #\newline
instead of letting the interpreter do all the job line by line (cutting it
etc.).
An example below with algebraic numbers à la Nemo (partially printed in
real/complex form). I really prefer your and my ways.
As one can see matrices are often very badly printed on screen, even if for
small sized matrices with small outputted elements that is a beautiful
work. Some options are available I think to better handle default mechanism
for matrices thought.

What do you pass to PRINC? Normal FriCAS way to print a literal
string is to use 'message', like:
(13) -> message(" 0.165528 0.830355 0.630221 0.0903032")$OutputForm
(13) 0.165528 0.830355 0.630221 0.0903032
Type: OutputForm
As you can see with correct literal string you get the expected output.

[fricas-devel] Struggling with OutputForm
Hello,
I am struggling with OutputForm and frankly I do not want to be angry
today. Maybe you have used it, even not a lot? My question is very
simple, how do I prevent OutputForm processing, or how to bypass
interpreter rules, just in case the interpreter has its own rules
also, from memory I think it has some "knowledge" about OutputForm.
That's simple, my output string is already formatted and I just want
to let FriCAS display it. Of course there is line length but I do not
understand very well what happens. Below is the output from PRINC
(without double quotes, essentially) and after from FriCAS. Why is
the second row cut???

The code:
if pprint then
--newLine()$DisplayPackage
ret : String := jl_string_eval_show(getind(m))$Lisp
ret := concat(" ", ret)
PRINC(ret)$Lisp
TERPRI()$Lisp
newLine()$DisplayPackage
TERPRI()$Lisp
ret pretend OutputForm
--concat("\n", ret) pretend OF
--PRINT(ret)$Lisp
