termios routines for Rakudo Perl 6

term-termios's Issues

Please "git tag" your RAKU modules with it's versions

Can you please set a specific "version" for your RAKU module in your META6.json file? You have a '*" now, which is known to make trouble and may not be supported within the RAKU tool chain (soon), say ZEF, FEZ, MI6...

And can you please "GIT TAG" your RAKU modules with it's version, similar and at the same time you maintain it's "version": "x.y.z" in your META6.json file, then and in the future?

I was told, this will happen "for free" going forward with mi6 anyhow, but for now it would be great if you spend those 2 seconds already now :)

"Tagging" is generally highly appreciated in regards to "reproducible builds" and here especially for the "Rakudo Star" modules

THANK YOU!

Cannot install Term::termios because it requires perl version 6.0.0

==> Fetching Term::termios
Please remove leading 'v' from perl version in Term::termios's meta info.
Term::termios requires Perl version 6.0.0. Cannot continue.

That's probably because of the contents of META.info?

Issue while installing

Originates from https://github.com/krunen/term-termios/blob/master/lib/Term/termios.pm6#L145

Use of Nil in string context

Test failures on Windows

Does TERM::termios only work under Unix or also under Windows?

Bug with zef temp dir

Came back after winter break to find that the REPL in raku was broken, complaining about a raku file missing from a temp dir.

Did a refresh install of raku latest with rakubrew, installed Terminal::LineEditor, worked.

Removed $TMPDIR/.zef, and the problem happened again. (assuming original problem was tmpdir getting cleaned after a reboot)

Did a force reinstall of Term::termios, and the problem was resolved. (This is one of the deps of Terminal::LineEditor)

This seems similar to ugexe/zef#546

resources was removed from meta file

Looks like this commit removed libraries/myhelper from resources, which has broken the module.

To reproduce the issue, I install Terminal::LineEditor which depends on Term::termios, then run raku, the repl doesn't load and continuously throws error
relevant part in the error is:

Use of uninitialized value element of type Any in string context.
Methods .^name, .raku, .gist, or .say can be used to stringify it to something meaningful.

Adding back libraries/myhelper to meta file resources fixes the issue for me.

raw mode not working on macOS

Hi

I was having issues with https://github.com/ab5tract/Terminal-Print not capturing input on macOS and after some research I've found it uses Term::termios under the hood to switch terminal into raw mode.

So I've tried to switch terminal into raw mode using following oneliner:

perl6 -e 'use Term::termios; my $termios := Term::termios.new(fd => $*IN.native-descriptor).getattr; $termios.makeraw; $termios.setattr(:DRAIN); $*IN.getc; die;'

And it dies instantly without waiting for any input. Am I right by saying that in raw mode reading from STDIN should be blocking action?

I'm using

Following the example provided on the main site, I am getting the error as described in the subject.
Here is a stack trace:

Consider migrating to "zef ecosystem"

Hello,

good to see you back. This dist continues to back up many of the most essential TUI distributions in the Raku world.

In the meantime, the old p6c ecosystem has been declining due to its obvious limitations - lack of versioning and author integrity. Please consider to release this module to the "zef ecosystem", using the fez tool.

Thanks in advance.

getc in raw-mode

Hi,

since there is no answer to this question: http://stackoverflow.com/questions/31958891/perl6-getc-in-raw-mode, maybe this is a bug.

.getc won't permit completely raw input

The example code is wrong in that the getc method will always wait for additional input in order to determine whether it is a combining character or not.

To actually do raw input, you need to set the IO::Handle (e.g. $*IN) to binary mode ($*IN.encoding(Nil);) and use $*IN.read(1) to read a single byte; note that this will give you a Buf instead of a Str. (A quick hack for that is $*IN.read(1).decode("latin-1"), especially since Buf is currently not as easy to work with as Str.)

The raw input mechanism may require a somewhat recent moarvm and matching rakudo to work properly.

Failed to open libmyhelper.so

When trying to install Term::termios in the rakudo-star Docker image, I get the following error:

The testing phase returns OK.

UPDATE: If I install build-essential first (which contains a C compiler and make), the module installs correctly. So it seems to be mostly a LTA error message.

Please "git tag" your RAKU modules with it's versions

As you closed #15 , this is a way of re-opening it again.

---

Can you please set a specific "version" for your RAKU module in your META6.json file? You have a '*" now, which is known to make trouble and may not be supported within the RAKU tool chain (soon), say ZEF, FEZ, MI6...

And can you please "GIT TAG" your RAKU modules with it's version, similar and at the same time you maintain it's "version": "x.y.z" in your META6.json file, then and in the future?

I was told, this will happen "for free" going forward with mi6 anyhow, but for now it would be great if you spend those 2 seconds already now :)

"Tagging" is generally highly appreciated in regards to "reproducible builds" and here especially for the "Rakudo Star" modules

THANK YOU!
