things to be done on the ℙ𝕖𝕡 / ℕ𝕠𝕞 system

A document about what needs to be done on ℙ𝕖𝕡 🙵 ℕ𝕠𝕞

7 may 2025

use the google gemini assistant to translate the rust or dart translator into other languages. This will actually save a huge amount of typing even if I need to correct the program. But the result seems remarkably good.
finish the rust translator, currently called /tr/dev.nom.torust.pss which will be called /tr/nom.torust.pss when it is working.

1 may 2025

add modulus operator to /eg/maths.parse.pss
update /eg/nom.syntax.reference.pss to allow trailing parse> labels and beginblocks (see /tr/nom.tolua.pss or /tr/nom.todart.pss )
cgi-script link on nomlang.org pages to allow basic editing/comments
link on icon images to show image information

27 april 2025

Format /tr/ translation scripts into html and make links to them.
in /eg/maths.parse.pss and /eg/maths.tolatex.pss change the exponent operator (^) to be right associative (because I forgot this basic rule of school mathematics).
write “/eg/maths.tollvm.pss” to convert a mathematical expression to llvm intermediate representation. This is mainly as an exercise and to learn a bit about llvm.

done

almost finished lua translator (need to do “stdin.stream” and “stdin.file” input types for very big files? )
add upper case headings to text.tohtml.pss (but not with trailing .... four dots.)
in /object/machine.methods.c change escape() and unescape() so that they do not reescape chars that are already escaped eg \\\\ should remain as is. Use the code from /eg/nom.todart.pss escapeChar to implement.
add go; and mark; syntax to pep interp but haven't recompiled asm.pp with bumble.sf.net/books/pars/compile.pss

27 mar 2025

show a solution to “dangling else” problem with nom
show solution to recognising { a^n b^n c^n : n>0 } with ℙ𝕖𝕡 🙵 ℕ𝕠𝕞
write a script that turns grammar descriptions as above with braces into html or latex. See wikipedia for the format.

23 mar 2025

make a help system for the /eg/text.tohtml.pss script which would explain the formats available for writing documents.
empty list item at end of doc may eat the whole document!
work on the dart translator.

19 mar 2025

wrap long lines in /eg/nom.tolatex.pss nicely so that I can make books in A4 with a bigger font.
make a vim macro command or abbreviation that adds translation instructions for a given language. Or put the macro in /eg/text.tohtml.pss .
make some format “attributes” for lists in html, for example to suppress the bullet points or make the list ordered etc.

17 mar 2025

More things to do

change sum() function in maths.tolatex.pss to take 3 arguments not two eg sum(0, :infinity, expression).
Or just make the sum function an operator, so that I can combine it with other expressions.
add stackmash as symlink in nom blog.

things done

Added a script* grammar token to the scripts at (eof) which means that a valid script/program has been successfully parsed. eg in nom.syn.ref.pss The new translator scripts have this grammar.
Consolidate grammar token error checking into one section just after the parse> label in the translation scripts. I have done this for /tr/nom.todart.pss and will use as template for other translators.
adapted /eg/nom.tohtml.pss to output L^AT_EX this is pretty simple since it is not a parsing script.
fixed mark/go bug in the translator scripts. Essentially if a new mark is created which has the same name as an existing mark then the existing mark should be deleted.
make nom.tolatex.pss to produce latex output for printing.
made a translation macro in the HTML formatter which will list languages that have good nom translators and links to the translator scripts.
remove parsing code from nom.tohtml.pss and just make the script colourise and print. This is better because don’t have to reformat statements.
make files automatically link in documents when they start with / such as /tr/translate.perl.pss . Directories work too such as the /tr/ folder.
done: autolink /eg/text.tohtml.format.html hope so.
done: added unordered lists. See /eg/text.tohtml.format.html for the details of the format. Basically list items start the line with - and end with a blank line or the end of the document.
done: check centre aligning images in eg/text.tohtml.pss
done: in blog.sh generate latex maths formula images and save in image/maths
done: put the abbreviation code which is in nom.tohtml.pss into
done: add help to eg/nom.syntax.reference.pss nom.syn.ref.pss
done: make a template script with errors and help and parse stack watch.
done: add equationset* token to eg/maths.tolatex.pss so that I can print lists of formulas and maths problems.
done: rewrite maths.tolatex.pss using new grammar in maths.parse.pss (not much to rewrite)
done: Improve unbalanced bracket error checking (in nom.syn.ref.pss
wrote a pretty printer for nom source code. eg look at colours in chromium view source, i.e nom.tohtml.pss and nom.tolatex.pss

13 mar 2025

Things to do on the ℙ𝕖𝕡 and ℕ𝕠𝕞 system.

rewrite translate.perl.pss using the new syntax at eg/nom.syntax.reference.pss
make script nom.syntax.recognise.pss based on script above which just says “yes: nom syntax ok” or “no: etc” This script would become the basis of an non-error checking nom parser.
add help system to eg/drawbasic.pss
generate headers in eg/ to html with text.tohtml.pss
make a new script text.tolatex.pss for printing a book
revise the docs at nomlang.org/doc to generate printed material

I need to debug the perl and python translation scripts in bumble.sf.net/books/pars/tr The perl one is not working much at all and the python one has a bug when running /eg/text.tohtml.pss

Include the document folder in the download.tar.gz
Also do the translations swift, rust, dart, lisp, forth, lua, zig
I would like to call these scripts “nom.tojava.pss” or “nom.todart.pss” etc.

Update the github ℙ𝕖𝕡 🙵 ℕ𝕠𝕞 repository.
Make sure ℙ𝕖𝕡 🙵 ℕ𝕠𝕞 can be downloaded with git and compiled with “make ”
write a table of contents parser

Add the “go;” syntax, go to the mark indicated in the tape cell

Change write; to writefile “name"; and writefile; (write to file” named in tapecell). Also make “readfile” with the same syntax. But “compile.pss” used write to sav.pp as a special process.

find the bug with pickwick papers (strange character hanging?)

compiler and translator error messages

token sequences

missing command like replace


    quoted quoted ; 
    quoted ;

trailing comma or dot


   quoted , quoted , {
   quoted . {
   message: 
     Truly, I would love just ignore that trailing comma at line x char y
       but I just cant, pedantry doesnt let me
