I was wondering if it was possible to run a selfwritten ruby program just like any other program by double-clicking an icon of some sort.
And if it's possible, how do I do it?
I wrote a little program for a friend but I don't want him to have to use the command line to run it, because that's rather inconvenient (unless there is a way to just double-click and the command line opens the program itself..).
Thanks for your help!
The simple answer that should work for all versions of Windows is to just create a simple batch launcher.
Create a .bat file. I usually just create a new .txt file via "right click > new > text document". Then rename it, highlight everything, including the extension, and rename it to something like run.bat. The .bat part is important. Once you rename it, the icon should change to gears. If you can't overwrite the extension, or Windows is still treating it as a text document, you'll need to either manually save it as a bat, or disable "hide file extensions" in the explorer settings so the extension can be changed.
Edit the bat file, and put into it something like:
#echo off
YOUR RUN COMMAND HERE THAT YOU WOULD NORMALLY TYPE MANUALLY
pause
Paste the command that you would normally run manually where the capital text is. The first line is so it doesn't repeat the commands back, and the pause is so if an error happens, the command prompt doesn't immediately close. This gives you a chance to read the error.
Save it and close it. Now, if you double click on the bat file, your program should run.
Multiple ways
if it's for occasional use and for one script only I would pack it
to a Windows executable with Ocra, then you can double click
the .exe itself or a link to it
same as above but use jRuby and create a .jar file, not for beginners though
the easiest: if you configure Windows to start/run .rb files with your ruby.exe you can double click the .rb files itself and they
will execute, they will have the red Ruby stone icon
if you run a .reg file to enable drap and drop on .rb files you can combine the previous technique to drop files on the script and
they will be the parameters to the script, see my answer here for the reg file
my favorite: copy the .rb to your windows "C:\Users\your_user\AppData\Roaming\Microsoft\Windows\SendTo\"
folder, then you can right click file(s) or folder(s) and select
sendto and select your script, the files or folder will again be the
parameters for your script
you can create a .bat or .cmd file that starts with the path to your ruby.exe and the script as parameter, use rubyw.exe if you
don't want output
I'm writing myself a GUI utility for use in a CMD window to navigate between folders,
rather in the style of the old Norton Change Directory utility for DOS.
When run, the app pops up a folder tree to allow the user to select a folder to which
to navigate and then closes and returns to the CMD prompt. At the moment, the way it
works is that it is run as the first command in a "main" batch file. It writes a secondary batch
file, in my app's folder under AppData, containing the commands to change drive and
directory to the folder the user selected, and the main batch file then invokes this
second batch file using CALL.
It works fine, but this way of actually changing the CMD window's current directory
strikes me as inelegant both from the point of view of needing to be run from a batch file
(so that the user's selection can be acted upon after my app has closed) and of
needing the secondary batch file to do the actual navigation.
So, my question is, how can my app send the instructions to the instance of CMD
that owns the window in which the app is run to the folder the user selected? I've tried doing a ShellExecute
of "CMD /K ..." but although that does indeed navigate to the
selected folder, it does so in a new CMD window, not the one my app is run in. The
conceptual gap I have is how to get the current CMD to act on my app's instructions
after my app has terminated.
Fwiw, I thought of trying to write the user's folder selection into an environment variable in the CMD window's environment for the CMD processor to
act upon from there, but this seems to require that the CMD window be opened via "Run as Administrator", which I definitely don't want.
Your program cannot influence the environment variables of the command interpreter because they're separate processes. Your program cannot change the directory of the command interpreter directly, either, because, again, they're separate processes.
You need to use a batch file because the command interpreter executes batch files internally. Since it's all the same process, the batch file has the power to change the current directory, and for that change to remain in effect after the batch file finishes running.
Therefore, you need some way for your interactive program to communicate the directory selection back to the batch file so that it can act on it.
Instead of writing the instructions to another batch file, you could write the result to standard output. Have the batch file capture that output into a variable, and then execute cd on that variable. The batch code would look something like this:
for /f "tokens=*" %%a in ('[select_dir.exe]') do (
set DIRSELECTION=%%a
)
cd /d %DIRSELECTION%
Your Delphi code would look like this:
writeln(selected_dir);
To allow that command to work, you'll need to make sure your program is marked as a console program, as with {$APPTYPE CONSOLE}. If it's not, then the batch file won't receive any output, and probably won't even wait for your program to finish running before proceeding. It's OK for a console program to display a TForm, just like a GUI program.
::Checks if there is a JRE installed
start "%USERPROFILE%\Downloads\ConfCompiler\Tools\CheckJre.exe"
When I copy and paste the file location above into Windows Explorer it works fine. But the program does not run from the batch file I have created.
The purpose of CheckJre.exe is to create new keys inside of HKEY_CURRENT_USER.
The keys are created when I simply run it from Windows Explorer. But the keys are NOT created when running it from the batch file. The batch file just results in displaying a command prompt window with showing CheckJre.exe with full path in title bar.
Does anyone have a hint why?
Command start interprets the first double quoted string as title for the command line window to open. For all options of command start enter in a command prompt window either start /? or help start.
You need to explicitly specify a title in your batch file because of the double quoted string to run CheckJre.exe.
Use in batch file:
start "Check JRE" "%USERPROFILE%\Downloads\ConfCompiler\Tools\CheckJre.exe"
I have just started using Compass within Ruby on Windows. In order to watch a directory for changes, I need to run cmd.exe in the Ruby directory and then use the command "compass watch C:\path\to\project".
I wish to make a shortcut that will open cmd.exe in D:\ruby\bin\ (Ruby directory) with a pre-filled string that I can simply complete and then press enter to execute. For example:
C:\ruby\bin>compass watch D:\path\to\_
...and then I simply type the project folder name and press enter.
I can create a shortcut that runs cmd.exe in C:\ruby\bin\ but I then have to type the rest.
I can create a batch file that runs cmd.exe in its default location and then changes directory to C:\ruby\bin, then executes compass watch C:\path\to\project
I can't figure out how to pre-fill the above command and have cmd.exe wait for me to input the relevant project directory before manually pressing enter to execute.
It's a pretty simple one liner...
Open Notepad or other text editor
Change directory (cd) to your Ruby directory
Execute 'compass watch'
cd C:\ruby\bin
compass watch
Go to Save As
Change 'Save as type' to 'All files'
Save as compass.bat
Run the file (double-click) to start polling for changes
Source http://omnitech-support.blogspot.co.uk/2013/04/how-to-create-batch-files-for-windows-8.html
Create a new shortcut wherever you want to be able to run it.
For the command line enter cmd /K compass watch.
Call it whatever you like (I suggest 'Compass Watch') and save it.
Right click on it and choose properties.
Change the "Start In" to the folder where your config.rb is.
You can also set the "Run" option to Minimized.
Save the changes to the shortcut.
Run the shortcut to set Compass watching for changes in the relevant files in the folders defined in your config.rb.
I have many scripts which I interact with from the command line. Everytime I need to use them, I have to open a command line window and copy+paste and CD to the path to the directory they are in. This is tedious (they are in a rather deep file system, so typing out the full path is a pain, copy+paste is better but not much). I tried to create a .BAT file that I could double-click on that would open a new command-line window in the folder the .bat file exists in but it does not work. It opens a new window, but the working directory is not the directory that .bat file is in. Here's what I've got after much googling (My cmd skills ain't so great):
cd %CD%
cmd.exe
I know from when I used Linux that Konqueror had a "Command-line window here" feature, and that's the effect I'm trying to get on Windows.
you probably want to do this:
cd /d %~dp0
cmd.exe
this will set your current directory to the directory you have the batch file in
Create a file named open_dos_here.cmd with the following lines:
%~d1
cd "%~p1"
call cmd
Put this file at any folder.
Then, go to your Send To folder (Win+E; Alt+D;shell:sendto;Enter).
Create a shortcut to point to this open_dos_here.cmd
Then, in any folder, select any file or sub-folder. Right-click and select "Send To" and then select open_dos_here.cmd to open the DOS in that folder.
You can just enter cmd into the address bar in Explorer and it starts up in that path. Likewise for PowerShell.
There's a simpler way -
start /d "folder path"
As a more general solution you might want to check out the Microsoft Power Toy for XP that adds the "Open Command Window Here" option when you right-click: http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
In Vista and Windows 7, you'll get that option if you hold down shift and right-click (this is built in).
I'm thinking that if you are creating a batch script that relies on the Current Directory being set to the folder that contains the batch file, that you are setting yourself up for trouble when you try to execute the batch file using a fully qualified path as you would from a scheduler.
Better to add this line to your batch file too:
REM Change Current Directory to the location of this batch file
CD /D %~dp0
unless you are fully qualifying all of your paths.
Another solution is to use a shortcut file to cmd.exe instead of a batch file.
Edit the shortcut's start in property to %~dp0.
You achieve the same thing, except it has the Cmd icon (and you can change this).
Some people don't like clicking on batch files without knowing what's in them, and some corporate network drives have a ban on .bat files...
The simplest command to do this:
start
You can always run this in command line to open new command line window in the same location. Or you can place it in your .bat file.
Most simple way in explorer is to Shift + right mouse click on the folder or on an empty space in the folder and click on Open command prompt here.
CMD will then start in that folder
I must say, I'm not sure if it works for Windows Vista and below, but it surely works for Windows 7, 8, 8.1 and 10.
Referring to answer of #Chris,
We can also go to parent directory of batch file and run commands using following
cd /d %~dp0..
<OTHER_BATCH_COMMANDS>
cmd.exe
To understand working of command cd /d %~dp0.. please refer below link
What does it mean by command cd /d %~dp0 in Windows
You could add a context menu entry through the registry:
Navigate in your Registry to
HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell
and create a key called "Command Prompt" without the quotes.
Set the default string to whatever text you want to appear in the right-click menu.
Create a new key within your newly created command prompt named "command," and set the default string to
cmd.exe /k pushd %1
You may need to add %SystemRoot%\system32\ before the cmd.exe if the executable can't be found.
The changes should take place immediately. Right click a folder and your new menu item should appear.
Also see http://www.petri.co.il/add_command_prompt_here_shortcut_to_windows_explorer.htm
When you are in the desired folder , just type CMD in your address bar
A bit late to the game but if I'm understanding your needs correctly this will help people with the same issue.
Two solutions with the same first step:
First navigate to the location you keep your scripts in and copy the filepath to that directory.
First Solution:
Click "Start"
Right-click "Computer" (or "My Computer)
Click "Properties"
On the left, click "Advanced System Settings"
Click "Environment Variables"
In the "System Variables" Box, scroll down and select "PATH"
Click "Edit"
In the "Variable Value" field, scroll all the way to the right
If there isn't a semi-colon (;) there yet, add it.
Paste in the filepath you copied earlier.
End with a semi-colon.
Click "OK"
Click "OK" again
Click "OK" one last time
You can now use any of your scripts as if you were already that folder.
Second Solution: (can easily be paired with the first for extra usefulness)
On your desktop create a batch file with the following content.
#echo off
cmd /k cd "C:\your\file\path"
This will open a command window like what you tried to do.
For tons of info on windows commands check here: http://ss64.com/nt/
Create a new file startCmdLine.bat in your directory and put this line in it
call cmd
That is it. Now double click on the .bat file. It works for me.
You can replace call with start, it will also work.
this code works for me
name it cmd.bat
#echo off
title This is Only A Test
echo.
:Loop
set /p the="%cd%"
%the%
echo.
goto loop
you can try:
shift + right click
then, click on Open command prompt here
Inside given folder click on the top Adddress Bar and type cmd and click enter
It will open command prompt with current folder address.
You can simply create a bat file in any convenient place and drop any file from the desired directory onto it.
Haha. Code for this:
cmd
