<rubyn00b>
I'm trying to create a subclass for a class that is an Enumerator by overwriting its #each method: `def each; super.each { |entry| yield entry }; end` However, when I run it, I get an infinite loop: `MyArray[1,2,3].each { |entry| puts entry }
<apotheon>
That's because your use of super.each is basically doing this:
<apotheon>
each.each
<apotheon>
Maybe you just want `def each; super {|entry| yield entry }; end` instead.
<rubyn00b>
Oh, `super` is for calling the original method? I thought it referred to the parent class's object.
<rubyn00b>
apotheon: thanks that works by the way.
<apotheon>
As I recall, #super refers to the parent class implementation of the currently executing method.
<rubyn00b>
Hmm, my mistake.
<apotheon>
glad to help
<apotheon>
It's late in the day, though, so my mental exhaustion might be imagining things.
<rubyn00b>
Where are you? It's just 5 pm here.
<rubyn00b>
Not too early for me, not too late.
<apotheon>
late in the mental day
<rubyn00b>
ah, haha
<apotheon>
I'm in northern CO, actually.
<apotheon>
. . . so similar time zone placement with you, apparently.

I personally operate on AZ time, though, because DST bugs the crap out of me.
<apotheon>
I haven't quite managed to shift myself to thinking in UTC, though.
<apotheon>
The next step after that is probably going to be Unix time.
<apotheon>
aka Unix epoch
<rubyn00b>
Time zones have become so irrelevant these days. Every day feels like living in a space shuttle, nowhere to go.

ljarvis, Sorry, I needed to tend to something else. It took me a moment to study your comment; I had set the double to respond to "class:" and set the class properly. Except that I put quotes around the class name, making it a string. Removing the quotes allows the test to pass.

sorry, I'm very inexperienced with ruby, and I'm trying to add some debug strings to a script, I'm seeing this: `log 'message', %[sent to #{config.http_url}:#{config.http_port}#{http_path}] unless config.quiet`
<lacrymology>
first I don't quite understand what the %[] syntax means, and how it works without any quotes.. been searching for it, but found nothing

secondly I'd like to add another log line like `log 'headers', (#{key}: #{value} for key, value in head)` (sorry about the pseudocode)

IDK if the %[] syntax will allow me to do something like head.each inside it, if that should go between #{} or what

The thing is I try to bootstrap ruby from a ruby version 1.9.x
<Thaodan>
I build miniruby to from 2.2 with 1.9 and then usin that I bootstrap 2.7.x
<ljarvis>
where did you get the 2.7 Ruby from?
<Thaodan>
sourcecode
<ljarvis>
grab a package from ruby-lang.org
<ljarvis>
I just installed one of those on a VM that doesn't have Ruby
<Thaodan>
it needs to be build from source
<ljarvis>
that _is_ from source
<ljarvis>
the difference is that it's packaged differently from the version on e.g. github
<Thaodan>
why is the source differently then from git? is the same script to convert that in the source tree?
<Thaodan>
mine fails when building ruby/tool/ruby_vm/helpers/dumper.rb:13:in `require': cannot load such file -- pathname (LoadError)

Thaodan, you should be able to install the OS version of Ruby, and some other tools, and then build Ruby from course if you like. Depending on your OS, you'll need a slightly current version of autoconf, make, gcc and libraries, SSL git, libffi.

<Thaodan>
The difference is that I build miniruby in between
<leitz>
Thaodan, usually I remove any OS ruby and gems, after I have the new ruby built.
<Thaodan>
I build for the OS. But my version is 1.9 so I can't bootstrap from it.
<leitz>
Thaodan, you don't actually need the ruby_admin_tools gem.
<Thaodan>
I use miniruby but then some requires aren't found
<Thaodan>
no
<Thaodan>
I don't need that
<leitz>
Thaodan, yeah, you have to build a 2.x version first. I think I targeted 2.2.
<Thaodan>
thats what I did but as miniruby
<leitz>
Have you tried to do an install with the 2.2 version?
<Thaodan>
Then I have to package that version
<Thaodan>
But I just want to use it during built
<leitz>
Then you can add any gems required and remove the OS Ruby.
<leitz>
Thaodan, what do you mean by "package"? Sorry if I missed that earlier.
<Thaodan>
Package like an rpm package
<Thaodan>
I create one
<leitz>
What I did was build 2.2 and get it running, and then turn around and build the later version (2.7 or 2.8).
<leitz>
That way you can remove the OS Ruby stuff, and then you can get rid of the 2.2 stuff once you have the 2.7 going. You can then package 2.7.
<leitz>
Make sense? The main difference is that you build a full 2.2 Ruby, instead of just miniruby.
<Thaodan>
I can't remove stuff during packaging. Its a clean build and I can't change the environment. But if its possible to use a full ruby in a different directory that could.
<Thaodan>
All requires files are in the dir of miniruby but it somehow doesn't find it

anyone know how to preserve literal quotes with Process.spawn?

Process.spawn("ruby -Ilib -e sleep \'120\'.to_i -- foo bar") # but here i don't
<Thaodan>
is loapath recursive?
<adam12>
imperator: Any idea if your Process.spawn shows `sh` as a parent?
<adam12>
imperator: I see sh as a parent when I run it (WSL2). The sh parent has literal quotes and then the Ruby process has no quotes. I'm guessing that sh is eating them, not Ruby.
<adam12>
imperator: Switching to the array invokation might get you what you want. It will probably bypass the shell and call execve() directly.

Hi, I need some help. I have a ruby script I created to make the configuration of cameras easy, which went great. Basically I just use httparty to use the cameras web configuration to send all the commands. Now I need to upload firmware too and am running into trouble.
<renosis>
I am using httmultiparty to upload a 56 mb firmware file. I get back a response of: Error: Image file was too short. The system upgrade failed.
<renosis>
I can use the same file to upgrade fine manually from browser. I notice a discrepancy in file size reporting between browser and what ruby reports.

renosis: How did you install httmultiparty? gem or bundler?
<renosis>
gem
<adam12>
What version of multipart-post is installed? gem list multipart-post
<adam12>
renosis: multipart-post had issues with content-length at one point in time I think; it might still.
drale2k has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<renosis>
ok, I'll give that a shot. thanks adam12
<adam12>
There's also Faraday, but it relies on multipart-post. It might suffer the same issue.
<adam12>
If you could recreate the bug with multipart-post I'm sure they'd appreciate the bug report, but I'm not sure it would be a right-in-your-face type of bug.
<renosis>
It has been difficult to get some diagnostic info for the problem, because I don't have access to the camera's web server. For all I know it could be some other problem and it is misreporting as file size issue. Their error messages aren't very descriptive either.

not Jruby. I just have a folder called camera-scripts on hard-drive, I call the firmware bin file from the same folder as the script is in currently.
<adam12>
renosis: OK. I think there was a multipart-post bug with Jruby for bytesize method calls. But I was just curious what the blob looked like from file(1)'s POV. If you can't get it, no issue.
<renosis>
I have a linux box behind me.

WSL (or whatever it's called) might offer a way to use the file command.

I don't recognize that.
<adam12>
It's probably just the magic bytes at the beginning. Likely unrelated.
<adam12>
Sometimes the magic bytes are used for determining content type. Not sure if that's happening here but if the POST had a Content-Type header and it was something weird from the magic bytes, maybe that would of been a clue.
<adam12>
I'm spitballing because I don't remember how multipart forms work off the top of my head.
<renosis>
I may have found a work around. Could just turn on ftp access on the cameras using the standard web interface tricks I used before. Upload using ftp client and apparently it will auto update if you do that.
<renosis>
Yup, ftp thing works. Gonna go that route instead, dirty but faster. Just gotta make sure I turn the ftp option off at the end of the script. Thanks for the help Adam12.
