I'm attempting to install ruby processing. I followed this tutorial:
https://github.com/jashkenas/ruby-processing/wiki/Getting-Started
After I rake ( before I install jruby ), all of the tests fail. I get the following result before every print out and not sure how to fix it.
WARNING: you need to set PROCESSING_ROOT in ~/.rp5rc
Following the tipp by Oscar here is an easy Copy & Paste solution for Mac Users:
echo PROCESSING_ROOT: "/Applications/Processing.app/Contents/Java" > ~/.rp5rc
The instructions on the wiki have been updated since you asked this question.
As is now suggested, you can use this gist to create your .rp5rc file. Create a new sketch in Processing using the contents of SetProcessingRoot.pde in the gist, and it will suggest the correct PROCESSING_ROOT value for your system and create the file. Note that you'll have to delete the default text ("enter your processing root here") and enter the suggested (or another) path.
Or, if you know the correct PROCESSING_ROOT path for your system, do the following:
echo PROCESSING_ROOT: \"correct_path\" > ~/.rp5rc

I need a function similar 'make' program.
If my file not exist or if file need update (modyfy time is before my other file) tell me true.
I have one file dependencies to other file. How update it only if neccesary.
You might want to use FileUtils.uptodate?.
uptodate?(new, old_list)`
Returns true if new is newer than all old_list. Non-existent files are older than any file.
In your example you can use it like this:
unless FileUtils.uptodate?('file_a', ['file_b'])
# file_a needs to be updated
end
require 'time_difference'
TimeDifference.between(File.ctime("FilenameA"), File.ctime("FilenameB.txt")).humanize
Using gem 'time_difference'
trouble with other lang than english (withouth .humanize You get number)
I have a chef recipe that looks something like this:
package 'build-essential' do
action :install
end
cmd = Mixlib::ShellOut.new("gcc -dumpversion")
cmd.run_command
gcc_version = cmd.stdout.strip()
If I execute the recipe on a system where gcc is installed, the recipe runs fine without errors. However, if I run the recipe on a system which doesn't have gcc install I get the error 'no such file or directory - gcc'.
I came to know about the chef two-phases stuff when trying to find a solution to my problem. I was expecting the package installation to satisfy the gcc requirement. How can I tell chef that this requirement will be satisfied later and not throw an error at compile time?
I tried the following, but the attribute does not get updated.
Chef::Resource::RubyBlock.send(:include, Chef::Mixin::ShellOut)
ruby_block "gcc_version" do
block do
s = shell_out("gcc -dumpversion")
node.default['gcc_version'] = s.stdout.strip()
end
end
echo "echo #{node[:gcc_version]}" do
command "echo #{node[:gcc_version]}"
end
Any help is appreciated. Thanks.
So okay, a few issues here. First, forget that Chef::Resource::whatever.send(:include trick. Never do it, literally never. In this case, the ShellOut mixin is already available in all the places anyway.
Next, and more importantly, you've still got a two-pass confusion issue. See https://coderanger.net/two-pass/ for details but basically the strings in that echo resource (I assume that said execute originally and you messed up the coping?) get interpolated at compile time. You haven't said what you are trying to do, but you probably need to use the lazy{} helper method.
And last, don't store things in node attributes like that, it's super brittle and hard to work with.
I'm trying to run a Perl script called WyD using Cygwin on Windows. Cygwin is installed at C:\cygwin64, and WyD is installed at C:\wyd\wyd.pl. Both are in the Windows PATH environment variable as C:\cygwin64 and C:\wyd respectively.
When running WyD with bash/Mintty using:
wyd.pl -b -e -t -s 3 -o "OUTPUTTEDWORDLIST" "TARGETFOLDER"
...I get the following error:
Can't locate object method "init" via package "wlgmod::odt" (perhaps
you forgot to load "wlgmod::odt"?) at /cygdrive/c/WYD/wyd.pl line 284.
Sometimes wlgmod::odt is replaced with wlgmod::doc or any other document type, but running the script always generates that same basic error. A previous answer to this question recommended installing several dependencies, which turned out to be a mere copy-paste of an answer for Ubuntu systems, and didn't solve the error, so I've decided to start at the beginning and re-ask the question with more details. I also have all Perl packages in the Cygwin installer installed.
After everything I've tried and done to get this script working, I can personally think of two possible causes for the error. Think of these as a guide more than anything else.
The error above references line 284 in the wyd.pl script, so it's possible that something in that script is hardcoded so that it doesn't work with Cygwin/Windows, or just generally has a compatibility bug. I don't understand Perl, so I can't confirm this.
I notice that the installation of WyD at C:\wyd contains a folder called wlgmod, and that folder contains all the files that the above error seems to be looking for; doc.pm, html.pm, jpeg.pm, etc. If those files exist in that directory but bash is unable to find them, maybe it's due to the fact WyD needs to be run from within Cygwin itself. I've only recently thought about this possibility, and my knowledge of both Cygwin and WyD is too sparse to definitively know how both work. Is it even possible to run WyD from within the Cygwin folder? It's not a package so can't be installed as one, and therefore I'm not sure how that would work.
Here are the relevant sections of the script:
# Module hash containing module name and supported file extensions
# Multiple extensions are seperated using ';'
my %wlgmods = (
'wlgmod::strings', '', # only used with command-line switch
'wlgmod::plain' , '.txt', # used for all MIME text/plain as well
'wlgmod::html' , '.html;.htm;.php;.php3;.php4',
'wlgmod::doc' , '.doc',
'wlgmod::pdf' , '.pdf',
'wlgmod::mp3' , '.mp3',
'wlgmod::ppt' , '.ppt',
'wlgmod::jpeg' , '.jpeg;.jpg;.JPG;.JPEG',
'wlgmod::odt' , '.odt;.ods;.odp'
);
...
# Initialize possible modules
foreach(keys %wlgmods) {
eval("use $_;");
my $ret = $_->init(); # line 284
# If module failed, add errortext and remove from hash
if($ret) {
$retvals .= "$_: $ret\n";
delete $wlgmods{$_};
$ret = "";
}
}
I've been using vim over ssh to work for a week or two now and all has been going great. Today I decided to add in some syntax highlighting, autocomplete, and some other general plugins. Set up vundle and went to work.
My current .vimrc can be found at https://github.com/scottopell/dotfiles/blob/master/.vimrc
I have cloned my vimrc and vim files onto my local ubuntu desktop and vim runs exactly as expected, no slowness on any files that I can find. Same plugins and same vimrc and no slowness on ruby files.
update
I can reproduce this issue with the following .vimrc
syntax on
and an empty ~/.vim folder.
However, vim on this vps is very slow with ruby/haml files. Much moreso ruby files. When I open any ruby file, startup takes about 2 seconds (timed with --startuptime). With a comparable length haml file, its about .5 seconds. This slowness isn't just on startup either, moving around and editing the file are both painfully slow.
Haml/erb(they are basically the same)
268.818 000.005: before starting main loop
848.871 580.053: first screen update
Ruby
199.613 000.004: before starting main loop
2937.859 2738.246: first screen update
Without syntax highlighting on the same ruby file as above

I have tried using mosh(http://mosh.mit.edu) and it doesn't help. not really relevant anymore
As you can see in my .vimrc file, I have tried a few different solutions to this problem.
I have tried running with all plugins disabled (I moved them all from ~/vim/bundle/PLUGINNAME to ~/vim/bundle/disabled/PLUGINNAME, is this correct?), set ruby path, set foldlevel to manual, disabled my colorscheme, nothing helps. see edit3
I can post the full startupttime log for any file if that will help.
I have tested a few other languages(php, c, python, vimL) and none experience any slowdown.
EDIT: Just to clarify, I am running an ssh session with ssh user#server then once inside the server I am doing vim file.rb.
EDIT2: I just tried accessing the server directly and the slowness persists without ssh, I have updated to reflect that this isn't a problem with ssh.
EDIT3: I can reproduce the issue with a .vimrc file that contains the single line syntax on with an empty ~/.vim folder
EDIT4 I uninstalled my compiled version of vim and any versions that I may have installed through apt, manually removed all vim stuff from my system, and I can run vim with vim -u NONE /path/to/file.rb then do :syn on and the issue will be there. The file in question is a rails controller, but like I've said, I can recreate it to some degree with most any file, but rails controllers see to be the worst.
The solution to this problem turned out to be the regex engine that vim uses.
The speculation on #vim on freenode is that the ruby syntax files use something that is slower on the new regex engine.
Any version older than and including Vim 7.3.969 has the old regex engine.
Add in set re=1 to your vimrc to force the old regex engine on any version newer (and don't forget to reload the file you're currently editing with :e).
Thanks to Houl, Dolio and dmedvinsky from #vim for help figuring it out.
I haven't had a chance to try the absolute latest version, there was a commit last night that may help with this issue. I will update this if I get the chance to try the bleeding edge version again.
You should set this tw options in your vimrc:
set ttyfast
set lazyredraw
If this is not solving your problem try to start vim without your vimrc to be sure that none of your current settings are screwing it up.
vim -u NONE
Two things that will drastically help speed up Ruby syntax highlighting are disabling cursor line and relative number for Ruby (if you use those).
I have the following in my .vimrc:
" Ruby is an oddball in the family, use special spacing/rules
if v:version >= 703
" Note: Relative number is quite slow with Ruby, so is cursorline
autocmd FileType ruby setlocal ts=2 sts=2 sw=2 norelativenumber nocursorline
else
autocmd FileType ruby setlocal ts=2 sts=2 sw=2
endif
I'm using vim 7.4.52 and none of these solutions worked for me.
According to this github comment on the issue (https://github.com/vim/vim/issues/282#issuecomment-169837021), foldmethod=syntax is responsible for the slowness.
Adding this to my .vimrc finally fixed it!
augroup ft_rb
au!
" fix the SLOOOW syntax highlighting
au FileType ruby setlocal re=1 foldmethod=manual
augroup END
Try setting your ruby path explicitly in your vimrc:
let g:ruby_path="/usr/bin/ruby"
see UPDATE at the bottom.
this may be helpful as a workaround -
i am using vim version
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jan 2 2014 19:40:46)
Included patches: 1-52
it is the stock version from
Linux Mint 17.1 Rebecca.
the php.vim syntax file is not version'd that i can see, but it sez last edit'd 28 aug 13.
it isn't a ruby project, but when editing a large php class file (
$ php -w test.inc | wc
2 2410 19220
) i note significant delays near the top of the class, but not above or below the class, and, notably, not toward the bottom of the class. as i attempt to insert new text near the bottom of the class, delay is minimal and seems to be proportional to the line number inside the class. "minimal" means almost instantly, "significant" means 1 to 1.5 seconds per character.
the file is approx 1800 lines with approx 500 lines of legit php and 1300 lines of comments and doc. the class begins at approx line 30 and ends at approx line 1700. it is conceded it's a bit large, but well documented :-\
if i insert
class dummy { }
in front of the original "class originalName {",
there is no delay anywhere in the file. this unsightly kluge permits vim/gvim to regain its responsiveness and could be considered a workaround. note no linefeed between the two, just
class dummy { } class originalName {
it can even be comment'd out:
/*class dummy {}*/class originalName {
additional info:
during this test, the plugins directory was moved.
with "set syntax=off", the problem completely disappears. this is NOT a fix.
setting the regular expression engine with
set regexpengine=1 (or any other number)
does not appreciably change the results.
based on these results, i would suspect the regular expression engine as well. my point is that diddling a bit with the syntax in ruby files may lead to a workaround.
UPDATE:
i have found that the issue is "caused" by setting php_folding to 1 (enabled). the vimrc i THOUGHT i was using was not, but at least some of the mystery is solved due to that mistake. a simple vimrc like this will induce the problem (for me, as least):
:syntax enable
:let php_folding = 1
this means my issue is totally unrelated to the ruby issue, but there may be a similar thing going on with the ruby.vim file. maybe not.
apologies for the deflection.
I tried most of these solutions but what ended up working for me the best was removing any plugins associated with airline.
Tim Pope's rails.vim provides a command :A (and a set of related commands) which opens the "alternate" file. For most classes, that's the test, and for the test, the class.
It would sure be nice to have that functionality in non-Rails Ruby projects. Is there a plugin which provides that? Bonus points if it helps me create the test file when I create the implementation file. :)
Our hero tpope wrote rake.vim too. It does the very same things rails.vim does but in Ruby projects.
I created the following command that makes it possible to do
:E /pattern/replace
to jump to the file that is the current filename and substituting pattern by replace
For example, if your tests files are in /test/code.js and your src files in /src/code.js you could write the following command:
command! -nargs=* Es :call EditSubstitute("/test/src")
command! -nargs=* Et :call EditSubstitute("/src/test")
to have the command :Es to jump from testfile to source file and the command :Et to jump from source file to testfile.
Here's the function that does that :
function! EditSubstitute(args)
if (len(a:args))<2
return
endif
let s:delimiter = (a:args[0])
let s:split = split(a:args,s:delimiter,1)[1:]
let s:fullpath = expand('%:p')
let s:bar = substitute(s:fullpath, s:split[0], s:split[1], "")
echo (s:bar)
silent execute('edit '.s:bar)
endfunction
command! -nargs=* E :call EditSubstitute(<q-args>)
I know this doesn't really answer your question at all... but I use VIM buffers to provide easy accessibility to a file and its tests.
I keep my test on top, and the file on the bottom. Then I can view both at the same time.
I use NERDTree to make browsing easier too, but that is not a per-requisite.
