LSE missing from DECset

Post by wboerhout@gmail.com » Sat Apr 15, 2023 3:49 pm

I just downloaded and installed E9.2-1 for x86 in orer to test some Fortran programs that I am working on.

I notices that LSE is missing from the DECset installation kit.

Is this permanent or temporary?

Can we get a official or unofficial response on whether LSE will be available at some time?

Regards,

For what it's worth, LSE was mentioned in this webinar as something which would come with V9.2: https://www.youtube.com/watch?v=eH8gAjoOkXI

The fact that it's not listed with the other DECset utilities makes me suspect there's some technical reason which is holding up the x86 port.

   I know nothing, but I'd expect a Language-Sensitive Editor to require
some non-trivial effort to support a new compiler (C++, for example?),
whose idea of that language might differ from that of some older,
nominally similar compiler.

The C++ guess seems like a pretty good guess.

Traditional VMS C++ support C++98.

clang support C++17 and a lot of C++20.

Huge change.

As far as I know, LSE is not written in C++ unless it's been rewritten in recent years.

"written in" != "support"

I'm well out of date, but originally LSE was written in TPU, and according to Wikipedia still is. However LSE needs to "understand" C++ in order to be sensitive to it, that will (at a guess) be the support issue.

But it could presumably be released without c++ language support, that cold be added later

That was my reaction. Just release note that it doesn't work with C++, but support will come in a future release.

> [...] Just release note [...]

   I'd expect such a release to involve more soon-to-be-obsolete work
than "Just [a] release note".  I suspect that hordes of paying customers
loudly demanding LSE (NOW!) without C++ support might justify it.  From
which I conclude ...
