On top of my Vagrantfile I have:
# -*- mode: ruby -*-
# vi: set ft=ruby :
But every time when I open the file, I have to select manually in SublimeText 3 that I wanna set the syntax to Ruby, so it'll be readable.
How can you set a filename to be opened as a ruby-file in this example. Because the file has no extension.
Your use case is exactly what ApplySyntax is written to address. In fact, I believe Vagrantfile is one of the default "samples", so you might not have to do anything. Also, comments that are handled in some special way on some editors does not apply to all editors (in this case, ST).
A translator completely messed up a yaml file by copying everything into word (don't ask).
I have already cleaned up the file using regexes, but the indent (spacing) is now missing; everything starts at the first character:
es:
default_blocks:
thank_you_html: "thank you text"
instead of
en:
default_blocks:
thank_you_html: "thank you text"
Do you have a good idea on how to automatically copy the format/structure/indent from the correct file (say en.yml) to the corrupt one (say es.yml)? (I'm using textmate 2.0 as editor)
Thanks!
Assuming the original and the translation contain exactly the same strings per line (except for the indentation problem), a quick&dirty script scanning the leading whitespace may solve this:
#!/usr/bin/env ruby
# encoding: UTF-8
indented = File.readlines(ARGV[0]).map do |l|
l.scan(/^\s+/)[0]
end.zip(File.readlines(ARGV[1])).map { |e| e.join }.join
File.open(ARGV[1], "w") { |io| io.write(indented) }
Save it, make it executable and call
./script_name.rb en.yml es.yml
Wouldn't mess with Textmate if this is not a regular task, but you could easily transform this to a command and either prompt for the two files via a dialog or select both in the file browser, open one of them in the current tab and differentiate them via environment variables ($TM_FILEPATH, $TM_SELECTED_FILES)
I am using the Community Edition of PyCharm.
When I put a break point in my python file and try to debug, always file cp1252.py opens and it goes to this line:
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
Do I need to do any specific setting for debugger in PyCharm?
Thanks for the help.
It turned out that I needed to force the source file to be opened as UTF-8 by adding this at the first line of my code:
# -*- coding: UTF-8 -*-
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
149.047 000.004: before starting main loop
152.912 003.865: first screen update
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.
File.exist? in not working with directory name having special characters. for something like given below
path = "/home/cis/Desktop/'El%20POP%20que%20llevas%20dentro%20Vol.%202'/*.mp3"
it works fine but if it has letters like ñ its returns false.
Plz help with this.
Try the following:
Make sure you're running 1.9.2 or greater and put # encoding: UTF-8 at the top of your file (which must be in UTF-8 and your editor must support it).
If you're running MRI(i.e. not JRuby or other implementation) you can add environment variable RUBYOPT=-Ku instead of # encoding: UTF-8 to the top of each file.
