I'm going through an RoR guide, and i'm stuck at a problem in topic "Static Pages" and currently I'm using the text editor Sublime Text 2 and whenever i follow instructions and do:
$subl .
or try
$subl public/hello.html
it outputs:
sh.exe" subl: command not found
any help would be very much appreciated..
-Marc
if using ruby version manager (i am only assuming because i had this problem), then the suggested command for the symlink must be modified at the user path:
ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/.rvm/bin/subl
notice the .rvm directory has been added to the path.
I've had a similar issue, the paths in $PATH were correct, and when I browsed to my local bin folder:
cd /usr/local/bin/
I could see the subl file / shortcut.
After pening this folder in finder with:
open .
I could see the icon looked incorrect (white), perhaps a previous version. Double clicking it also gave an error, so I manually copied the subl file over, after expanding contents of the Sublime Text 2.app.
If you drag the file over, it will create a shortcut, if that doesn't work then first duplicate the subl file in its original position, then drag over the duplicate and rename correctly. Or just give the correct permissions on it.
Hope this helps

I need to convert my iOS project to 64-bit friendly (to get rid of compiler warnings, as in this question. The solution apparently is to run ConvertCocoa64.
I've managed to locate ConvertCocoa64 (which is no longer included in /Developer/Extras/64BitConversion/ConvertCocoa64) as the Apple docs suggest, but here (search for Auxiliary Tools)
So I've download the script. But my question is, how do I run this on my project? Please assume a total newbie level of knowledge here when it comes to the terminal and running scripts. Do I drop the script inside my project folder and just double click it? Or do I access it from the terminal? The docs say run this command:
/Developer/Extras/64BitConversion/ConvertCocoa64 `find . -name '*.[hm]' | xargs`
But since that folder doesn't exist, where do I run it?. I tried dropping the script in the Developer folder, but when I type ConvertCocoa64 it says command not found.
Find where the command is located now. You'll want to run it in the terminal using the full path to the command, as in your example, just with the real path.
A good way to get the full path is to locate the command in the Finder and drag it to an open terminal window - this also "escapes" any spaces in the path for you. The easiest way to hit all your files as arguments to the command is to cd (change directory) to your project first (in the terminal).
This should get you set up to follow the directions you have.
If I'm not mistaking, to run script, you should place dot . before command. Doesn't really matters, where script is situated as long, as it doesn't rely on it heavily
> cd ~/path/to/script/dir/
> ./ConvertCocoa64 ...
When I tried the instructions at https://arclanguage.github.io/, after I entered "racket -f as.scm" I got "-bash: racket: command not found".
I also tried these instructions for downloading Arc on Linux:
https://sites.google.com/site/arclanguagewiki/getting-started/install-arc
I installed racket from download.racket-lang.org, and when I got to "./arc" in the Arc/Nu section, the output from the terminal was "env: racket: No such file or directory".
The Arc Language Wiki (linked to above) indicates that the official installation instructions are out of date, and says little about how to install Arc on OS X. I tried googling for a general solution to "command not found" and "No such file or directory" problems but couldn't find anything that let me fix the problem. I also tried moving my racket and arc downloads to different combinations of places.
Arc runs on top of Racket, which although you've downloaded it, does not appear to be in PATH, the environment variable containing the list of folders that Bash searches for executables.
The immediate fix is to, instead of running Arc as racket -f as.scm, run it as /path/to/racket/bin/racket -f as.scm. (The Racket documentation points out that the Racket executable is in the bin folder of the Racket folder you downloaded).
Assuming that works, the fix is to add the Racket bin folder to your PATH variable. Open up ~/.bashrc in your favorite text editor, and add a line export PATH=/path/to/racket/bin:"$PATH".
Once you do this, you'll have to open a new Terminal before this change will take effect. But once you do, you should be able to just run racket -f as.scm, and it will work.
This MEAN-stack tutorial describes using Bower to install AngularJS in your public folder. One of the steps describes creating a file called ".bowerrc" in your test-app folder. However, Windows won't let you create a file without a name. How do I accomplish this on a Windows system?
on the command line (make sure to cd into your working directory), issue this command:
touch .bowerrc
This will also work for other files common to webdev like .htaccess and .gitignore
Note: If you haven't installed git bash for windows, you may not have support for the touch command. In that case (as mentioned in one of the comments here), the easiest way to accomplish this is via the cli with:
echo "" > .bowerrc
To create a file that starts with a "." in Windows, you just need to add a trailing ".".
So, simply name your file ".bowerrc." instead of ".bowerrc".
See https://superuser.com/questions/64471/create-rename-a-file-folder-that-begins-with-a-dot-in-windows for more information and more detailed solution if this doesn't work for you.
Another way to accomplish this is through Notepad++.
Create the file in Notepad++
Set the encoding to "Encoding in ANSI" (click "Encoding" in the menu bar)
Save the file as .bowerrc (change the "Save as type:" to . which is one list item up from *.txt)
Simply rename the file you created:
C:\project> ren bowerrc .bowerrc
I am using Sublime Text 2 while following Michael Hartl's Ruby on Rails Tutorial.
The specific portion of the tutorial to which I am referring can be found at http://ruby.railstutorial.org/book/ruby-on-rails-tutorial (ctrl+F "Listing 5.26").
I am able to create the spec/support file. However, when trying to create the spec/support/utilities.rb file, I receive the message "Unable to save ~/rails_projects/sample_app/spec/support/utilities.rb".
Does anyone know why this might be?
Someone on the Sublime Text forum seems to have had the exact same problem: http://www.sublimetext.com/forum/viewtopic.php?f=3&t=8570&p=36922#p36922
This issue sounds like it's a result of incorrect permissions or ownership of the folder. Change directories (cd) so you're outside of the folder where you're creating the .rb file and type:
ls -l
This terminal command lists the permissions attached to all files/folders in that directory. If "root" is listed as the folder owner, change its owner by typing:
sudo chown YOUR_COMP_USER_NAME FOLDER_NAME/
You should now be able to save files from inside that folder.
To diagnose this, first find out if it's an issue in Sublime or your file system:
Does that file already exist? Try looking for it on your file system (not using Sublime).
Verify that you have permission to write to that file. Use "ls -la" on the command line to show the file permissions.
Are you able to create and/or save that file using any different editor, for example TextMate, or Notepad?
The following sublime plugin fixed the Unable to save... bug
https://gist.github.com/3779601
The folder spec/support doesn't exist, and sublime won't create the missing folder, so it errors.
You just need to make the spec/support folder , then sublime will save the file.
I also highly recommend installing the AdvancedNewFile plugin ( Video of it action thanks to Jeffrey Way and NetTuts+ ) , which you can grab straight from Package Control.
It creates files, parent folders if needed, and if you try to create a file that already exists, it opens it instead.
This can happen if you are trying to create the file within a directory that does not currently exist. For ex. I was unable to save
~/rails_projects/sample_app/app/views/shared/_error_messages.html.erb
via the "subl" command from the Terminal because I was missing /shared/ folder. Hope that helps.
so #knice almost had it, I ran into the same problem with permission when starting my first rails project on mavericks.
as mentioned if you run ls -l you'll see your folder / files listed with their permissions
I solved this by changing ownership recursively with the following command from outside my project directory
sudo chown -Rv <your_username> <your_path_and_foldername>
for example if you're in your folder in terminal you should cd .. and then
sudo chown -Rv username ruby_proj/
the -R is for recursive meaning it will apply to all files and folder contained within the folder you specified, and the v after just produces verbose output, showing you which folder and file permissions have been changed.
Hope that helps someone else.
I would like to be able to access the current working directory in my vimrc.
For example, I can access the current file by using %.
Specifically,
I have the following line in my vimrc:
map ,l :!latex %
When it runs everything works fine, except the resulting dvi and other files are stored in my home directory instead of my current working directory.
Any suggestions?
See :help autochdir. Vim can automatically change the current working directory to the directory where the file you are editing lives.
Otherwise, if you want to do this manually, see :help cd and :help lcd.
see :he filename-modifiers
:!latex % -output-directory %:h
Most likely, you're running vim from your home directory, so it is the current for him. The latex command, being invoked from vim, also therefore has the home directory as current.
You probably know this, and want just to extract path from the filename and supply it as an argument to -o option of the latex command. Just use the shell capabilities:
:!latex % -output-directory `dirname "%"`
I am not sure that it's -output-directory option, but you get what you asked for--a directory name of the file you're editing.
