我昨天第一次尝试在 HTML 文档中使用“Tidy”,结果...
/tmp/temp_textmate.Z2P0KX:30:in `<main>': undefined method `empty?' for nil:NilClass (NoMethodError)
我没有对包中的代码做任何事情......
#!/usr/bin/env ruby -wKU
require ENV['TM_SUPPORT_PATH'] + '/lib/ui.rb'
require ENV['TM_SUPPORT_PATH'] + '/lib/exit_codes.rb'
result = `"${TM_TIDY:-tidy}" -f /tmp/tm_tidy_errors -iq -utf8 \
-wrap 0 --tab-size $TM_TAB_SIZE --indent-spaces $TM_TAB_SIZE \
--indent yes \
${TM_XHTML:+-asxhtml --output-xhtml yes} \
${TM_SELECTED_TEXT:+--show-body-only yes} \
--enclose-text yes \
--doctype strict \
--wrap-php no \
--tidy-mark no`
status = $?.exitstatus
at_exit { File.unlink('/tmp/tm_tidy_errors') } # Clean up error log
if status == 2 # Errors
msg = "Errors: " + File.read('/tmp/tm_tidy_errors')
TextMate.exit_show_tool_tip msg
elsif status == 1 # Warnings - use output but also display notification with warnings
log = File.read('/tmp/tm_tidy_errors').to_a.select do |line|
! (ENV['TM_SELECTED_TEXT'] and (line.include?('Warning: missing <!DOCTYPE> declaration') or line.include?("Warning: inserting missing 'title' element")))
end.join rescue nil
unless log.empty?
options = {
:title => "Tidy Warnings",
:summary => "Warnings for tidying your document (press escape to close):",
:log => log
}
TextMate::UI.simple_notification(options)
end
end
if ENV['TM_SOFT_TABS'] == "YES"
print result
else
in_pre = false
result.each_line do |line|
unless in_pre
tab_size = ENV["TM_TAB_SIZE"].to_i
space, text = /( *)(.*)/m.match(line)[1..2]
line = "\t" * (space.length / tab_size).floor + " " * (space.length % tab_size) + text
end
print line
in_pre = true if line.include?("<pre>")
in_pre = false if line.include?("</pre>")
end
end
问题线是unless log.empty?
。
我在 OS X 10.6.6 上运行 TextMate 1.5.10 (1631)。我最近安装了 rvm 并将默认 Ruby 升级到 1.9.2,尽管强制 TextMate 使用 1.8.7 并没有解决问题。
