[12:29:46] MarkBilk: Please, how do I get ri to tell me about Tk. I have Tk built in -- I ran a small program using it.
[12:51:39] MarkBilk: Installer for Windows.
[12:52:58] MarkBilk: ri works for other things, e.g., String.
[12:54:09] MarkBilk: ruby 2.3.3p222 (2016-11-21 revision 56859) [i386-mingw32]
[12:56:42] MarkBilk: Tk isn't in the gems directory.
[13:08:26] MarkBilk: hanmac: Which command should I use from there, considering that ri already works for classes other than Tk?
[13:09:12] MarkBilk: This? gem rdoc --all --ri --no-rdoc
[13:12:38] MarkBilk: It parsed the docs for all the gems, but ri Tk or ri tk still gives nothing.
[13:20:34] MarkBilk: hanmac: the other suggestion is: gem install rdoc-data and then: rdoc-data --install
[13:52:00] MarkBilk: hanmac: I ran that too. Didn't help.

[15:46:21] MarkBilk: havenwood: I can require 'tk' in irb, so I seem to have it, but not as a gem. In Ruby 2.3.3 .

[16:41:08] MarkBilk: I had problems running an external program (wget) from Ruby in Windows 8.1. %x() works better than backquotes. I had to put a copy of wget in the current directory, and call it like this %x(.\\wget #{img_url}) . There are two backslashes between the period and the wget. I don't know how it will print out here.
[16:46:11] MarkBilk: Even though I made sure that the directory with the original copy of wget was on the PATH, and I could run it from the command-line, I couldn't run it from Ruby until I made a copy in the current directory.

[01:55:02] MarkBilk: I just did gem install rdoc-data and it took a very long time. But ri Array still says: Nothing known about Array.
[03:51:29] MarkBilk: havenwood: Thanks! rdoc-data --install fixed it.
[03:55:16] MarkBilk: btw, I installed the devkit and installed hpricot.gem from source. But most of the methods don't work. So I'm learning more Ruby so I can deal with Nokogiri.

[01:08:13] MarkBilk: havenwood: Thanks! It works! Now I just have to figure out why. Don't know the map {} business. Presumably that's standard Ruby. I'll look it up.

[14:17:51] MarkBilk: I'm using Ruby 2.3 in MSWindows, trying to use the print method with two objects (OK in 2.4.1 doc), but it gets a syntax error on the comma after the first object. How do I find the docs for Ruby 2.3?
[14:22:36] MarkBilk: print ("elemTag.content = ", elemTag.content) elemTag.content is a string (nokogiri)
[14:30:32] MarkBilk: Thanks! That fixed it.
[16:38:27] MarkBilk: I used hpricot years ago and it was wonderful. But the gem won't install in Ruby2.3 in MSWindows 8.1, so I'm trying to use Nokogiri and having a very hard time. Element.text is supposed to be a String, but it won't print out.
[16:39:33] MarkBilk: Unable to find spec for #<Gem::NameTuple hpricot, 0.8.6, x86-mswin32>
[16:39:33] MarkBilk: When I try to install the hpricot gem I get: ERROR: While executing gem ... (Gem::Exception)
[16:44:17] MarkBilk: tgragnato: is there anything other than nokogiri?
[16:51:01] MarkBilk: Is oga easy and fun like hpricot, unlike nokogiri?
[16:53:24] MarkBilk: Great! Thanks!
[23:54:48] MarkBilk: nofxxxx: Problem with Nokogiri: tutorial at http://ruby.bastardsbook.com/chapters/html-parsing/ He says: puts page.css("title")[0].text # => My webpage. Correct, and works on my webpage too: http://www.cosmicpenguin.com/linux/ But change "title" to "img" (of which there are two on my page) and it does not print anything. hpricot was MUCH better.

[18:55:21] MarkBilk: I do this in irb and get an error message: NameError: undefined local variable or method `hpricot' for main:Object Help, please.
[18:55:21] MarkBilk: Hi! I'm trying to use the gem hpricot. I haven't programmed in Ruby for years and that was in Linux. Now I'm stuck in Windows 8.1. My Ruby directory is called Ruby23. irb works. The instructions for hpricot say to install it by: gem install hpricot
[19:01:05] MarkBilk: ERROR: Could not find a valid gem 'hpricot' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)

[19:30:35] MarkBilk: eputnam_: got it!

[19:48:30] MarkBilk: Unable to find spec for #<Gem::NameTuple hpricot, 0.8.6, x86-mswin32>
[19:48:30] MarkBilk: eputnam_: Giving complete path. With -local it says: invalid option: -ocal With /local it looks for a gem "/local" and gives the SSL error. With no option it gives: ERROR: While executing gem ... (Gem::Exception)

[19:53:03] MarkBilk: The gem file is 379KB, just like the web page says, so it's the right file. But the installer doesn't like it.
[19:54:33] MarkBilk: The directory is called Ruby23.
[19:55:56] MarkBilk: gem --version 2.51
[19:56:14] MarkBilk: sorry 2.5.1
[20:06:30] MarkBilk: Successfully installed rubygems-update-2.6.12

[20:07:30] MarkBilk: Now for the tricky bit...
[20:09:36] MarkBilk: Unable to find spec for #<Gem::NameTuple hpricot, 0.8.6, x86-mswin32>. gem --version 2.5.1!!!
[20:10:46] MarkBilk: Don't tell me I have to reboot the computer!
[20:13:00] MarkBilk: I downloaded and used the update gem because I wouldn't know where to put whatever is in the zipfile.
[20:15:32] MarkBilk: I wouldn't mind tossing the Ruby 2.3 and getting a better one if that would help.
[20:17:50] MarkBilk: But hpricot is 5 or 6 years old and I thought that an older version of rubygems might be better suited to it. But this one can't update itself.
[20:18:44] MarkBilk: Hey maybe cmd.com has the old version in cache.
[20:19:28] MarkBilk: how do you do rehash in Windows?
[20:22:05] MarkBilk: Seems unlikely that gem would say it successfully updated and then not do it.
[20:32:00] MarkBilk: eputnam_: gem and gem.cmd were read-only and had same old dates as other files. Trying update again.
[20:39:00] MarkBilk: eputnam_: I can't change the permissions. How do you become superuser in Windows?
[20:42:06] MarkBilk: right-click just gives me a menu for copy, paste etc
[20:44:17] MarkBilk: got an answer from google
[20:48:58] MarkBilk: hold on, didn't make sense, trying another
[20:56:31] MarkBilk: The control panel says I aleady AM admin.
[21:00:16] MarkBilk: The Ruby23 directory says read-only -- applies only to files within the directory. I unset read-only, but it comes back.
[21:06:11] MarkBilk: Here's a favorite picture: http://www.cosmicpenguin.com/images/kmfms-final.jpg
[23:24:29] MarkBilk: Is there a good tutorial for using nokogiri for HTML? They all seem to be for XML only. (I wanted to use hpricot but the gem won't load in Windows.)
