How to modify output colors?

[TLINDEN]

So, in the fancy_irb page it says something about DEFAULT_OPTIONS, which is undefined in my irb session and if I configure it via .irbrc it doesn't have any effect. The problem is, that the rocket output lines are printed in yellow (on a white terminal) and are thus unreadable.

I tried, for example:

Irbtools.replace_library_callback :fancy_irb do
  FancyIrb.start :colorize => nil
end

but this doesn't seem to get called.

Hi and thanks for the feedback!

How to adjust the colors depends on what exact output should be changed. By default, one thing which is yellow are Ruby symbols (which is caused by the current Wirb default color schema). If this is your problem, try to change it like this:

# in .irbrc, instead of require "irbtools"
require 'irbtools/configure'
Irbtools.add_library_callback "wirb/wp" do
  Wirb.load_schema(:ultra)
end
Irbtools.start

If this does not solve your issues, please elaborate and/or post a screenshot.

Yes, symbols are the problem, but the code above doesn't have any effect either.

Here's my actual .irbrc:

# -*-ruby -*-

require 'irb/completion'
require 'irb/ext/save-history'
require 'irbtools/configure'

require "awesome_print"
AwesomePrint.irb!
# see also .aprc

IRB.conf[:SAVE_HISTORY] = 10000
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-history"
IRB.conf[:AUTO_INDENT] = true

$LOAD_PATH.unshift('.')

require 'irbtools'

def history(inc=nil)
  if inc then
    puts Readline::HISTORY.entries.grep(inc).sort * "\n"
  else
    puts Readline::HISTORY.entries * "\n"
  end
end

Irbtools.add_library_callback "wirb/wp" do
  Wirb.load_schema(:ultra)
end

Irbtools.start

And here's how it looks:

PS: I also tried to disable awesome_print with no effect as well

Please try replacing require "irbtools" with require "irbtools/configure"

Thanks a lot, that solved it! Love it :)

Great to hear!

Btw: I am also using a white background, so I'll look into making a more general purpose default theme for Wirb some time.
