Some random thoughts: I appreciate the original simplicity of K & R, "The C Programming Language", 2nd Edition, and the relatively simple semantics of ANSI C89/ISO C90 compared to …

I have compared both Modula-2 and Oberon-2 to Go, but have not compared Active Oberon to Go. This was for purposes of creating a top-down, predictive, recursive descent parser for …

IMHO, Oberon-2 WithStmt has much cleaner syntax than Go TypeSwitchStmt. WithStmt is easier to parse, more general and it doesn't need the Primary "." "(" "type" ")" at the beginnin…

Try this, it is highly recommended: "C Programming: A Modern Approach," 2nd Edition by K. N. King is selling for 111 USD, covering C89/C99 but the First Edition, covering C89 is on…

You possibly can use command-line redirection but whether OBNC can read directly from console output, I am not sure.

If I use module Out to write to STDOUT, is there a way for OBNC Oberon to Read the contents in that console window, so it can be treated as input.

You don't, at least if the syntax/semantics is as complex as Python! Recommendation: Find a subset grammar for Python, by doing a search on computer science classes on university s…

Yes, it displays correctly in HN. Now I can submit some content that best uses UpArrow for synthesized attribute in AG. Thank you HN for supporting Unicode!

This is supposed to be "Upwards Arrow with small triangle arrowhead: 🠁 It enters ok, lets see if it HN allows this Unicode character.

Interesting article. There is both left and right recursion in the definition of , but this EBNF (Wirth notation) uses iteration only: number = digit { digit } [ "." digit { digit …

Josh Lospinoso, the author of this blog, has now corrected this to read "pointer to const int" C declaration syntax confounds even the experts. I highly recommend this article to a…

"... const int* x_ptr_3 = &x; // (3) ... Finally, we see the preferred approach, which is taking a const pointer (3)" Not a const pointer, but a pointer to const int.

Rust popular? Tiobe language rankings for May 2019: Rust is ranked 34th at 0.335%, below Lisp and Prolog. Go is ranked 19th at 1.114%. C is ranked 2nd at 14.233% Rust does not have…

C++ is a huge and complex language compared to C. [Compared size of the standard reference document for each.] C++ is complex to parse. Clang and Gcc use back-tracking to parse C++…

Dijkstra's timeless advice. Also recommend: "On the Design of Programming Languages" N. Wirth CS-TR-73-403 "Hints on programming language design" C.A.R. Hoare "The Essence of Progr…

Doesn't say what tool was used to do the syntax highlighting colorization. Or was it done by hand?

A limited comparison of C, C++, Go, Rust: Go and C seem to have a large number of available software tools. Based on the "size" of the reference documentation alone, C and Go appea…

Assume ASCII characters: ORD('a') - ORD ('A') = 32 IF ('A' <= ch) & (ch <= 'Z') THEN ch := CHR(ORD(ch) + 32) END

You need to look at TUIs (Text User Interfaces).

Answering my own question, Geany has "Sending text through custom commands" and ability to add custom commands via "Send Selection to->Set Custom Commands" But it looks like this j…

I generally agree with Lucas' sentiments re GUIs and in his other article "In Praise of Plain Text." But I currently select portions of text with a mouse by highlighting it, and th…

I am not taking sides, because today's Ford Co is not saddled with Henry Ford's controversies, and both MIT and Ford are large organizations. I don't know who is right, a jury migh…

I found a LALR grammar for Rust on GitHub, compatible with Bison. But it does not closely track the published Rust Grammar nor syntax rules in the Rust Reference. (See Rust-lang DO…

I looked at the Rust site and their published grammar. It is VERY incomplete, missing entire productions. I cannot determine if the syntax of Rust is "better" than that of C. At le…
