peql(actual, expected=:unknown_peql_token, msg=nil) click to toggle source

Puts+eql? == peql Performs a equal comparison and outputs the result to console in the form

“#{msg}: Expected #{expected}, but got #{actual}”

expected may be kept empty, in which case the msg is adjusted

# File lib/cem/ccommon.rb, line 22
def peql(actual, expected=:unknown_peql_token, msg=nil)
  
  if expected == :unknown_peql_token
    puts "#{msg}: Didn't know what to expect and got '#{actual}'"
  else  
    if actual == expected
      puts "#{msg}: Expected '#{expected}' and got it!"
    else
      puts "#{msg}: Expected '#{expected}', but got '#{actual}!"
    end
  end
  
end
wsl?() click to toggle source

Returns true if this script is running on the Windows Sub-System for Linux, i.e. under Linux where the host is Windows.

If true, interoperability with Windows is possible.

# File lib/cem/ccommon.rb, line 96
def wsl?
  @@wsl ||= File.file?('/proc/version') && File.open('/proc/version', &:gets).downcase.include?("microsoft")
end
wslpath(path, mode = "") click to toggle source

If on wsl? then the given is converted from a Windows path to a Linux path (e.g. “C:" becomes ”/mnt/c/“)

Uses the wslpath command, passes mode to wslpath:

-a    force result to absolute path format
-u    translate from a Windows path to a WSL path (default)
-w    translate from a WSL path to a Windows path
-m    translate from a WSL path to a Windows path, with '/' instead of '\'
# File lib/cem/ccommon.rb, line 111
def wslpath(path, mode = "")
  return path if !wsl? 
  
  return `wslpath #{mode} '#{path}'`.strip
end
