perl6-readline's Introduction

Readline

Readline provides a Perl 6 interface to libreadline.

XXX This will probably be a frontend to Readline::Gnu when that's factored out. XXX For the moment keep all the code here in the Readline module.

Installation

Please make sure that libreadline is installed beforehand, the tests will fail otherwise. If libreadline is installed but the tests still fail, please note that the Perl 6 package searches a given set of directories for libreadline.{so,dynlib}.* files, otherwise it defaults to v7. If your libreadline installation isn't on any of these paths, or requires non-standard setup, please file an issue.

For those of you on Linux Debian and Linux-alike systems, you should be able to get the latest version with this CLI invocation:

	sudo apt-get install libreadline7

(I'd prefer to use LibraryCheck, but it fails inside the 'is native()' method call.)

Using zef (a module management tool bundled with Rakudo Star):

    zef update && zef install Readline

Or alternatively installing it from a checkout of this repo with zef:

    zef install .

Usage

See the examples/ directory in this project.

Testing

To run tests:

    prove -e perl6

perl6-readline's Issues

Failure on OS X.

With version 7.0.003 from macports on 10.12.6, I get the following errors:

===> Testing [FAIL]: Readline:ver<0.0.2>:auth<github:drforr>

Panda required?

Panda is listed as a requirement, but it doesn't seem to be.

Only noticeable if you're using zef to install everything.

Error installing on OS X 10.11.3

The error is Cannot locate native library 'libreadline.so.6': dlopen(libreadline.so.6, 1): image not found. Tried installing immediately on top of the newest release of Rakudo Star, since Readline was recommended at the launch of the repl.

Failure Summary
----------------
Readline(
    *test stage failed for Readline: Tests failed)

non-standard libreadline path in termux Android terminal emulator

I'm on an aarch64 phone running Android 10 and termux as a Linux environment.

I got rakudo+zef working a while back, but the Readline test phase fails as in #34, because on this specific system libreadline (v8) is located in

/data/data/com.termux/files/usr/lib/

That's accessible as $PREFIX/lib/, so I would suggest adding that to the original list of searched directories, i.e. in Rakudo terms, look through

%*ENV<PREFIX>/lib/

if that environment variable is set.

A working solution for me, as in #34, was to symlink my actual libreadline to the so.7 file the search defaults to.

Issues installing on Slackware 14.2 x64

I get error:
===> Testing: Readline:ver<0.0.2>:auth<github:drforr> Failed test 'initialize' at t/02-base.t line 10 Cannot locate native library 'libreadline.so': /usr/lib64/libreadline.so: undefined symbol: UP
And more of them, very similar.
I check for mentioned in error file with:
$ ls -l /usr/lib64/libreadline.so lrwxrwxrwx 1 root root 16 Jan 17 2017 /usr/lib64/libreadline.so -> libreadline.so.6
So I do not know how to fix that.

Doesn't work with readline 8

This is Rakudo version 2018.12 built on MoarVM version 2018.12
implementing Perl 6.d.

Arch rolled out readline 8 yesterday. Now this happens:

Error in REPL:
I ran into a problem while trying to set up Readline: Could not instantiate role 'ReadlineBehavior'

Trying to reinstall with zef produces this error repeatedly:
Cannot locate native library 'libreadline.so.7': libreadline.so.7: cannot open shared object file: No such file or directory

Feature Request: Get current readline buffer (rl_line_buffer)

I would like a method to get the current readline buffer. This is useful when I'm creating a custom function that is bound to a key, so that I can do actions based on the previous text.

This value is stored in the rl_line_buffer global variable, so cglobal('readline', 'rl_line_buffer', Str); would work.

Test failure on Debian/unstable

Tests are failing with:

I think prove6 is tripped by the blank line.

I could not find why t/02-base.t prints this blank line on stdout.

Module is broken with Readline 7.0

https://lists.gnu.org/archive/html/info-gnu/2016-09/msg00009.html
Readline 7.0 has been out almost a month, and it will be out of Arch's testing repository in a day or two.
Here is the error:

Is it possible to have custom completions?

I'm not very familiar with Readline, but it seems that in order to define custom tab completions, one needs to assign a callback function into rl_completion_entry_function. Is this currently possible?

readme shouldn't refer to ufo any more

ufo doesn't work any more - i suppose it's because of all the CompUnitRepo stuff we have now.

Failed test 'free-keymap lives'

I'm running Centos 6. I have installed the libreadline5 libs.

# ll /lib64 | grep readline
lrwxrwxrwx  1 root root   18 Apr  1 12:41 libreadline.so.5 -> libreadline.so.5.2*

-rwxr-xr-x. 1 root root 264K Jun 22  2012 libreadline.so.6.0*

It looks like it's still looking to version 6

I tried moving libreadline6 out of /lib64 and symmlinking to libreadline5 but it gave me the same error.

After symmlink

Readline no longer loads the shared library under 64-bit Slackware Linux 14.1

Having the hard-coded library version built in to newer versions caused NativeCall to fail while testing:

==> Testing Readline
t/01-load.t .. ok

# Failed test 'initialize'
# at t/02-base.t line 10
# Cannot locate native library 'libreadline.so.6': libreadline.so.6: cannot open shared object file: No     such file or directory

    # Looks like you failed 1 test of 1

# Failed test 'dumpers'
# at t/02-base.t line 13

This was because my system had only libreadline.so.5 installed.

However, after patching the module to attempt loading v5 instead of v6 of the library, it still failed to load do to undefined symbols. The same occurs after building and installing gnu libreadline.so.6.3.

The following symbols are undefined in both library versions:

This may be due to recent NC work (from what I'm told on #perl6).

Install failure on OpenBSD

There are a couple problems with getting this to install on OpenBSD:

symbols from ncurses need to be loaded before symbols from readline can be used
some of the symbols the library uses don't exist in the default readline library, but do in ereadline (the readline library installed with pkg or from ports)

I made a gist with the default test output, test output when loading ncurses symbols, test output when loading ncurses symbols and using ereadline, a diff of the changes I made to get the tests to pass, and the output of nm -g for the default readline library, in case they help.

Fails to install on Ubuntu 18.04 amd64 with libreadline5 and 7

Installation fails with libreadline5 and 7. This ticket may be related to #12, but it doesn't pick libreadline5 either.

The installation seems to be looking for 'libreadline.so', while this system has:

$ dpkg -S libreadline.so*

Fails to build on M1 Macs

on M1 Macs, /usr/local is protected by SPI, so Homebrew is installed under /opt/homebrew instead. Readline.pm has a hard-coded reference to /usr/local/opt/readline, which is not there on M1s; it's /opt/homebrew/opt/readline instead. It should check to see which one exists before proceeding.

Module fails to install

Following documentation:
$ panda update && panda install Readline

throws following:

Potential difficulties:
To pass an array, hash or sub to a function in Perl 6, just pass it as is.
For other uses of Perl 5's ref operator consider binding with ::= instead.
Parenthesize as (...) if you intended a capture of a single variable.

Please, consider accepting commit c029773 which might fix this, and see warning too.

Can't install on macOS without version-specific libreadline symlink

===> Testing: Readline:ver<0.1.5>:auth<github:drforr>
[Readline] # Failed test 'initialize'
[Readline] # at t/02-base.t line 10
[Readline] # Cannot locate native library '(null)': dlopen(libreadline.7.dylib, 10): image not found

...followed by a bunch of failures tied to its inability to find that file. I happen to be running readline 8, so a symlink from libreadline.8.dylib to libreadline.7.dylib fixed the problem, but why is it looking for that specific file? If it's going through all the trouble of looking for specific symbols in the library, why must it also look for a specific major version? It seems like it could at least try the unversioned libreadline.dylib file either first or as a fallback.
