mruby-require's Introduction

mruby-require

mruby-require adds require support to mruby. This is based on iij's fork of mruby: https://github.com/iij/mruby

install by mrbgems

MRuby::Build.new do |conf|
  if ENV['OS'] != 'Windows_NT' then
    conf.cc.flags << %w|-fPIC| # needed for using bundled gems
  end
    # ... (snip) ...
  conf.gem :github => 'mattn/mruby-require'
end

To work properly, mruby-require must be the last mrbgem specified in the build configuration. Any mrbgem specified after mruby-require is compiled as a shared object (.so) and put in build/host/lib (full path available in $:). For loading them at runtime, see the next section.

Requiring additional mrbgems

When mruby-require is being used, additional mrbgems that appear after mruby-require in build_config.rb must be required to be used.

For example, if using mruby-onig-regexp, you should add the following to your code:

require 'mruby-onig-regexp'

Requiring mrbgems in defaults

Set MRUBY_REQUIRE environment variable as comma separated values like following

MRUBY_REQUIRE=mruby-onig-regexp,mruby-xquote

mruby-require's Issues

Crash on requiring bundled gems

On requiring a bundled gem, I get the following crash, whichever is the gem I require:

> require 'mruby-complex'
mirb(13889,0x7fff7df1f300) malloc: *** error for object 0x10066cc30: pointer being realloc'd was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

This happens for both C-compiled gems as well as pure ruby gems. Conversely, requiring plain ruby files and bytecode compiled files (.mrb) works as expected.

bundled gem does not include mrblib

How should one go about getting the gems mrblib included?

Issues with mruby 3.2.0

Hi,

I've found an issue with mruby 3.2.0.

Given these two files:

entry.rb

$:.unshift '.'

require 'zip'

and zip.rb

a = [1,2,3]
b = [:a, :b, :c]

p a.zip(b)

I am getting the error:

trace (most recent call last):
        [10] (unknown):0
        [9] (unknown):0:in require
        [8] /home/sean/Syncthing/code/c++/taylor/zip.rb:4
        [7] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in zip
        [6] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in each
        [5] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in zip
        [4] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in each
        [3] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in zip
        [2] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in next
        [1] /home/sean/Syncthing/code/c++/taylor/zip.rb:4:in next_values
/home/sean/Syncthing/code/c++/taylor/zip.rb:4:in resume: can't cross C function boundary (FiberError)

It works as expected with mruby 3.1.0

Please let me know if you require any more information

Strange behaviour on Windows

Hi,
on my fork, I notice a trance behaviour on Windows. When I compile a .mrb file and then require (or load it), if the original source .rb file contains a function, whose name has exactly 10 characters (regardless the actual string), then loading the file has no effect, and no error is raised.

Note that this only happens on Windows. Mac and Linux do not present this issue. Additionally, if I run the same compiled .mrb compiled script with the standard mruby interpreter I get the correct behaviour. Can you replicate this?

Steps to replicate:

create a test.rb script which defines the function def abcdefghij(); end
compile it with mrbc
launch the mirb interactive interpreter and load "./test.mrb"
test for existence of abcdefghij(): you should get an undefined method error.

More or less character in the function name do work. Exactly 10 characters and it doesn't.

`Kernel` prefix are attached to the namespace

preparing foo.rb

class Foo end

and doing the following:

require './foo.rb'
p Foo

outputs Kernel::Foo, while CRuby outputs Foo. Is this behavior what you intended?

Thank you in advance.

After mruby #bfd2a539, classes declared in required files are lost

This must have something to do with changes in mrb_load_irep_cxt(), but I can't help in spotting the solution...

Unable to bundle gem

I have a very minimalist build_config.rb to test that:

MRuby::Build.new do |conf|
  if ENV['VisualStudioVersion'] || ENV['VSINSTALLDIR']
    toolchain :visualcpp
  else
    toolchain :gcc
  end

  enable_debug

  conf.gem 'path/to/mruby-gem_a'
  
  conf.gem :github => 'mattn/mruby-require'
  
  conf.gem 'path/to/mruby-gem_b'

Here mruby-gem_a and mruby-gem_b are just dummy names.
I tried using minirake and rake, the same problem arise:

mruby-require causing issues with other mrbgems

Hi,

I'm using mruby-require, and although it appears to work fine, when using it, other mrbgems such as mruby-onig-regexp or mruby-eval stop working, just as if they weren't being included.

Am I doing something wrong or could this be a bug ?

regards,
Ricardo

Attempting require on .mrb file causes crash

Tested on Windows, and built with mingw-w64 5.1

Using require from either mirb or a script ran with mruby will work fine for a standard .rb script, but attempting to load .mrb bytecode compiled from that same script causes an immediate crash.

build failed with latest mruby

require not working with mruby

I try to create an executable from a simple Ruby program. If the file contains a simple puts with a string and I use the following commands
mrbc -Btest load.rb
gcc -std=c99 -I/root/mruby/include -I. test_stub.c -o load /root/mruby/build/host/lib/libmruby.a -lm -ldl
everything runs well calling ./load display my string.
But if I add
require 'yaml' or require 'ostruct' or require 'json' before, execution simply display nothig, no crash either...
I have added the following line in mrbgems/default.gembox file
conf.gem :core => "mruby-yaml"

and
conf.gem :github => 'ksss/mruby-ostruct', :branch => 'master'
conf.gem :github => 'mattn/mruby-json'
conf.gem :github => 'mattn/mruby-require'
in build_config.rb after conf.gembox 'default'
After make clean a call to objdump on libmruby.a show that the modules are in the lib...
But it doesn't work!
What am I doing wrong ?

Implement `require_relative`

Working with Ruby I found Kernel#require_relative function quite useful. It might be a good idea implement it for mruby as well.

Error when compiling: "Don't know how to build task 'some/path/mruby-2.1.1/build/host/mrbgems/mruby-array-ext/src/array.o'" and "relocation R_X86_64_PC32 against symbol `mrb_ary_push' can not be used when making a shared object"

mruby 2.1.1

Summary

I ran into this when trying to add the mruby-require gem. The error I get depends on the order I do stuff in.

To reproduce the first, I run rake clean, add the mruby-require gem to the build config (if not there), and try to compile.

Relevant-looking output:

Don't know how to build task 'some/path/mruby-2.1.1/build/host/mrbgems/mruby-array-ext/src/array.o' (See the list of available tasks with `rake --tasks`)

To reproduce the latter, I run rake clean, compile with no gems, add the mruby-require gem to my build config, and try to compile again.

Fix

The relevant bits are that "To work properly, mruby-require must be the last mrbgem specified in the build configuration. Any mrbgem specified after mruby-require is compiled as a shared object" (as per the README, which explains the errors above) and that the default build config includes this line conf.gembox 'default' which adds a bunch of default gems (these would be the gems that the above errors are complaining about)

Make sure that your conf.gem github: 'mattn/mruby-require' line is below the conf.gembox 'default' line.

It's easy to make this mistake because the default build_config.rb has the "Use mrbgems" section above the "include the default GEMs" section.

After I made that fix, it compiled without issue. Will close since this is really just here to hopefully save some other people some time in the future.

Does not compile since mruby #8cd42f6

Due to changes to mrb_intern APIs.
