I'm learning Rust and can't get the Cargo command working; I'm not sure if it's my mistake or an error.
This is what I typed in the /src directory:
src [path]$ editor Cargo.toml
The reply I got was:
-bash: editor: command not found
If you literally typed editor Cargo.toml, then you're trying to run a program called editor, with an argument called Cargo.toml. The message you get is the system letting you know that you don't have such a program.
To do what you want to do you can either:
Write open -t Cargo.toml in MacOsX, which opens the file with the system's default text editor (TextEdit, or whatever you may have changed it to).
Or you can bypass this and open the file directly from your favorite editor's window; the intent here is for you to open and edit the file with any text editor you have installed.
This means you don't have the editor program installed on your system. Depending on your environment, you might try installing it or using another text editor (say, vim for unix).

I'm trying to get sublime to highlight smalltalk .st files but am running into some trouble.
A quick search found this package, but after adding the repository like it says in the README, I don't see the package that its supposed to add when doing Package Control: install package.
I also tried looking into this one but am completely lost when it says This syntax file can be converted to .tmLanguage using PackageDev 'Convert to PList'. Place the converted file in Packages/Smalltalk/Smalltalk.tmLanguage and reopen any .st file.
Can anybody help me out please? I'm running ST3 on MacOSX.
The installtion instructions using Package Control did not work for me either, but you can take the language file, Smalltalk.tmLanguage, from Smalltalk syntax for Sublime Text 3 and use the manual installation instructions you cited:
Place the file in Packages/Smalltalk/Smalltalk.tmLanguage
As you asked about macOS, on macOS this means:
/Users/<your user name>/Library/Application Support/Sublime Text 3/Packages/Smalltalk/Smalltalk.tmLanguage
The Library folder might be hidden by default. Use the Terminal or Finder's Go ▶︎ Go To Folder… to access it.
For Smalltalk/X you can download a highlighting package at - sublime highlighting for smalltalk/X called Smalltalk.sublime-package.
You can copy it to the path provided by #MartinW above.
I'm running into odd behavior with the Interactive-Haskell repl in emacs. When I source a file, the emacs mini buffer shows a series of interactive prompts:
Start a new project named 'myproject'?
Cabal dir (guessed from myproject.cabal):
Build target (empty for default):
Set current directory:
If I leave either the cabal directory or the current directory to the default value of the project directory, the repl is unresponsive. I get a lambda prompt in the interactive Haskell window, I can type, but when I press enter, it never evaluates. The cursor stays on the same line as if I did not press enter at all.
If I change both of those directories to some path other than my project directory, then the repl behaves normally and evaluates expressions as expected.
This is a known bug. and a good catch!
The pull request https://github.com/haskell/haskell-mode/pull/1116/files solves it.
I am trying to make the CoqIDE Vim plugin work on Windows 8.1. When I source the plugin from Vim, I get this error message:
coqtop.opt: command not found.
So I looked up the plugin documentation, and found the part that seems relevent:
"coqtop" should be accessible on PATH. If "coqtop" is not in your PATH, add 'let CoqIDE_coqtop = "/path/to/coqtop"' in your "~/.vimrc".
I'm not sure what this means, but I'm guessing that there is some file or directory named coqtop that must be made visible to vim. So I opened my Coq installation directory and searched for coqtop. The search hits are:
coqtop
coqtop.cmi
coqtop.1
coqtop.byte.1
coqtop.opt.1
The obvious first candidate here is coqtop. When I click it, it opens an interactive Coq console. But when I use the let CoqIDE_coqtop command to link this file to Vim and load the plugin again, I get:
C:Program Files (x86)Coq^Hincoqtop.exe: command not found.
Another thing that looks problematic is the file type. As you can see from the error message above, the coqtop file has an .exe extension, which is specific to MS-DOS and Windows. But I don't think the plugin was written to work with .exe files...
I also tried using all the other search hits as coqtop, to no avail.
Does this mean that the plugin is useless on Windows? If someone can confirm that I'll just give up and use other IDEs. But if possible I'd really, really like to keep using Vim.
I am trying to run a .run file in cygwin, but I always seem to get this error:
Unable to start '~.run': There is no application associated with the given file name extension.
I needed to be a superuser, so I tried using the command: cygstart --action=runas "$#"
I read somewhere that cygstart is for invoking registered Windows handler, so this may be the problem, but I am unsure. Is there any way that I can run my .run file as a superuser using cygwin?
Well, as has been said, no application is associated with .run files on your
system. So you can do that one of two ways
Call the file with the program, example
cygstart notepad.exe ~.run
Tell the registry what to do with unknown extensions
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Unknown]
#=""
[HKEY_CLASSES_ROOT\Unknown\shell\Open\command]
#="notepad.exe \"%1\""
This question is not related to Cygwin but rather to Windows. cygstart works the same as Windows' start. That means, if you use [cyg]start file.extension it works very similarly as if you double-click on that file in Windows Explorer.
Therefore if you configure Windows to do what you need when you double-click on your *.run file, cygstart will work fine too.
I think that easier is to use appropriate extension which Windows already knows. It depends on what you have inside your *.run file. If it's executable, use exe extension, if it's batch script, use cmd or bat, if it's JavaScript, use js etc.
If you use Linux or some derivation, you need to execute the .run file with an absolute path, even if you have already navigated to the appropriate directory containing the file. See here:

I just downloaded and started using Vim so I'm still a bit confused with it. I've been watching tutorial videos and I see that I can open Vim by typing vim in command. However when I do it I get
'vim' is not recognized as an internal or external command, operable program or batch file
Did I need to install something else? Also I want to code and compile C in vim, would I need to install a compiler?
You have to invoke Vim (or gvim, the GUI application) with the full path, e.g.
"C:\Program Files\vim\vim74\vim.exe"
The Vim installer doesn't add the location to the PATH. In Windows, you can create a shortcut (*.lnk) in your Start Menu, or re-run "C:\Program Files\vim\vim74\install.exe", which has an option to install batch files to C:\Windows, or manually add "C:\Program Files\vim\vim74" to your PATH via the Control Panel.
Vim is just a (very advanced and powerful) text editor, so it ships with syntax highlighting for most programming languages, but unlike IDEs, it doesn't come with the full toolset of compiler, linker, debugger, etc. You need to separately install that (e.g. mingw, or Microsoft's compiler from the Windows SDK, or any other).
C:\>vim somefile.txt
During Vim (for Win32) install, you have the option to install batch files for launching vim from the command-line.
make sure you install vim properly. (https://www.vim.org/download.php)
On Windows. Don't forget to set the environment variables (simply add \vim\vim**; at the end of the classpath)
Type vim at command line (gvim.exe will start the Graphic user interface software).
If you want to compile and run c program using the command line, you should download the GCC Compiler and follow the same procedure as mentioned before (The classpath thing). Then you can compile C program using gcc command.
