Replacing dos executable names with custom short names? - path

I've been using the command prompt to practice assembly programs and I wish to use notepad++ as the editor. Adding notepad++ to the path will do the job but I don't want to type 'notepad++' each time I have to edit a file. Is there a way I can change the name of the executable? Without having to rename the application name.

You could create a quick batch file called, say, npp.cmd. That batch file only needs to have this in it:
#"C:\Program Files (x86)\Notepad++\notepad++.exe" %*
Put npp.cmd somewhere in your path (I have a C:\tools directory for batch files like this) and off you go.

Or associate your assembler sources with Notepad++.
ASSOC .asm=asmfile
FTYPE asmfile="C:\Program Files (x86)\Notepad++\notepad++.exe" "%1"
Then you can edit *.asm files with Notepad++ by double clicking on it in Explorer or by writing it's name in command prompt.

Erlang : exception error: no match of right hand side value {error,enoent} while reading a text file

I am currenly working on an erlang project and stuck in reading the file. I want to read a text file which is in the /src folder where all the erlang and a text file are in the same structure. Then too, I am not being able to read the file despite of specifying file paths. Any help would be appreciated.
start() ->
{ok,DataList} = file:consult("Calls.txt"),
io:format("** Calls to be made **"),
io:fwrite("~w~n",[DataList]).
The data file stores contents like : {john, [jill,joe,bob]}.
Try add folder name to the path or try set full patch to the file:
1> {ok,DataList} = file:consult("src/Calls.txt").
Notes: the error {error,enoent} mean that the file does not exist or you don't have a rights to read/write current file, for this case need set 777 rights or similar.
If you need to use src/call.txt, then this simply means that your IDE (or you) has created a src folder in which the calls.txt file has been placed. At the same time, the IDE is using a path that only includes the top level folder (i.e., the root folder for the IDE project). So src/call.txt must be used in that case. This isn’t a problem with Erlang, or even the IDE. It’s just the way your project is set up.
You can do either of two things. Move the calls.txt file up one level in the IDE file manager, so that it can be referenced as calls.txt, not src/call.txt. You can also just change the path to “calls.txt” before you run it from the command line.
enoent means "Error: No Entry/Entity". It means the file couldn't be found. When I try your code, it works correctly and outputs
[{john,[jill,joe,bob]}]

how to find and deploy the correct files with Bazel's pkg_tar() in Windows?

please take a look at the bin-win target in my repository here:
https://github.com/thinlizzy/bazelexample/blob/master/demo/BUILD#L28
it seems to be properly packing the executable inside a file named bin-win.tar.gz, but I still have some questions:
1- in my machine, the file is being generated at this directory:
C:\Users\John\AppData\Local\Temp_bazel_John\aS4O8v3V\execroot__main__\bazel-out\x64_windows-fastbuild\bin\demo
which makes finding the tar.gz file a cumbersome task.
The question is how can I make my bin-win target to move the file from there to a "better location"? (perhaps defined by an environment variable or a cmd line parameter/flag)
2- how can I include more files with my executable? My actual use case is I want to supply data files and some DLLs together with the executable. Should I use a filegroup() rule and refer its name in the "srcs" attribute as well?
2a- for the DLLs, is there a way to make a filegroup() rule to interpret environment variables? (e.g: the directories of the DLLs)
Thanks!
Look for the bazel-bin and bazel-genfiles directories in your workspace. These are actually junctions (directory symlinks) that Bazel updates after every build. If you bazel build //:demo, you can access its output as bazel-bin\demo.
(a) You can also set TMP and TEMP in your environment to point to e.g. c:\tmp. Bazel will pick those up instead of C:\Users\John\AppData\Local\Temp, so the full path for the output directory (that bazel-bin points to) will be c:\tmp\aS4O8v3V\execroot\__main__\bazel-out\x64_windows-fastbuild\bin.
(b) Or you can pass the --output_user_root startup flag, e.g. bazel--output_user_root=c:\tmp build //:demo. That will have the same effect as (a).
There's currently no way to get rid of the _bazel_John\aS4O8v3V\execroot part of the path.
Yes, I think you need to put those files in pkg_tar.srcs. Whether you use a filegroup() rule is irrelevant; filegroup just lets you group files together, so you can refer to the group by name, which is useful when you need to refer to the same files in multiple rules.
2.a. I don't think so.

Windows 7 - Add Path

I need to add a new path (sumatraPDF) on my PATH variable.
I don't know why it does not work...
I think everything is right but when I try to execute sumatrapdf.exe from CMD it cannot find the program.
This is what I did:
The path is correct, I checked it 1000 times.
The idea is use LaTeX with sublimetext and when I save a .text file sumatra has to open and show to me the result. If I want that I have to add the path of SumatraPDF... but it does not work.
I think you are editing something in the windows registry but that has no effect on the path.
Try this:
How to Add, Remove or Edit Environment variables in Windows 7
the variable of interest is the PATH
also you can type on the command line:
Set PATH=%PATH%;(your new path);
Another method that worked for me on Windows 7 that did not require administrative privileges:
Click on the Start menu, search for "environment," click "Edit environment variables for your account."
In the window that opens, select "PATH" under "User variables for username" and click the "Edit..." button. Add your new path to the end of the existing Path, separated by a semi-colon (%PATH%;C:\Python27;...;C:\NewPath). Click OK on all the windows, open a new CMD window, and test the new variable.
I founded the problem:
Just insert the folder without the executable file.
so Instead of:
C:\Program Files (x86)\SumatraPDF\SumatraPDF.exe
you have to write this:
C:\Program Files (x86)\SumatraPDF\
In answer to the OP:
The PATH environment variable specifies which folders Windows will search in, in order to find such files as executable programs or DLLs. To make your Windows installation find your program, you specify the folder that the program resides in, NOT the program file itself!
So, if you want Windows to look for executables (or other desired files) in the folder:
C:\PHP
because, for example, you want to install PHP manually, and choose that folder into which to install PHP, then you add the entry:
C:\PHP
to your PATH environment variable, NOT an entry such as "C:\PHP\php.exe".
Once you've added the folder entry to your PATH environment variable, Windows will search that folder, and will execute ANY named executable file you specify, if that file happens to reside in that folder, just the same as with all the other existing PATH entries.
Before editing your PATH variable, though, protect yourself against foul ups in advance. Copy the existing value of the PATH variable to a Notepad file, and save it as a backup. If you make a mistake editing PATH, you can simply revert to the previous version with ease if you take this step.
Once you've done that, append your desired path entries to the text (again, I suggest you do this in Notepad so you can see what you're doing - the Windows 7 text box is a pain to read if you have even slight vision impairment), then paste that text into the Windows text box, and click OK.
Your PATH environment variable is a text string, consisting of a list of folder paths, each entry separated by semicolons. An example has already been given by someone else above, such as:
C:\Program Files; C:\Winnt; C:\Winnt\System32
Your exact version may vary depending upon your system.
So, to add "C:\PHP" to the above, you change it to read as follows:
C:\Program Files; C:\Winnt; C:\Winnt\System32; C:\PHP
Then you copy & paste that text into the windows dialogue box, click OK, and you should now have a new PATH variable, ready to roll. If your changes don't take effect immediately, you can always restart the computer.
The path is a list of directories where the command prompt will look for executable files, if it can't find it in the current directory. The OP seems to be trying to add the actual executable, when it just needs to specify the path where the executable is.
Try this in cmd:
cd address_of_sumatrapdf.exe_file && sumatrapdf.exe
Where you should put the address of your .exe file instead of adress_of_sumatrapdf.exe_file.

Delphi Path Variables

In the Delphi IDE, the path to the Delphi installation is specified as $(DELPHI). I am wondering if there is a way to create my own path indicators, such as $(MY_LIBRARY) or something similar. I thought $(DELPHI) was specified as an environment variable, but apparently not. Any ideas? (I'm using Delphi 7)
In Delphi 2010:
select Tools -> Options
select "Environment Variables"
specify either System, either User variable
For Delphi 5 you can add them from windows Environment variables
right click on My computer > properties > advanced > Environment variables
In Delphi 2010:
I know many of the XML tags in the Project.dproj can be used like this. (For exemple, $(DCC_DcuOutput), $(DCC_ExeOutput)...).
Maybe it is possible to add your own XML tags in the file and use them afterward. Though I'm not sure if they'll be preserved by the IDE.
Also of note is when your using the command line compiler, the file RSVARS.BAT located in the BIN directory of the current Delphi installation is what creates some of the environment variables for child processes. (for example BDS and BDSCOMMONDIR).
In Windows 7 (and Vista is similar) click the 'start' button, right-click 'computer', 'properties' and then 'advanced system settings'. Click 'Environment variables' and you're now able to create new ones as global (system), or just for the current user (you). For example 'MyVar'.
Now in a delphi path, refer to MyVar as $(MyVar).
MyVar will now be visible in batch files too as %MyVar%.
There is an alternative workaround -- use SUBST to assign a virtual drive letter to the root of the folder you would be using $(MyFiles) if you could and then just use that.
For Example if you have files in deep directory, you'd go to the command prompt and type:
SUBST M: "C:\users\Me\Delphi Files\My Components"
and then you could refer to it by M:

What is the basic setup on SVN to work on a Rails app?

Lets say, I setup my svn host, like: http://www.example.com/svn
Then I create my project at a folder like: /home/me/workspace/my_app
I want to Setup my svn client and ignore files like tmp/* log/* db/schema.rb and such, so what are the commands on console for that? If possible can you write what the full sequence of commands to set this up?
obs: I have found no GUI that suit my needs on Ubuntu kdesvn / rapidsvn :(
Using TortoiseSVN, you could simply use the ignore menu item, but I guess you're not using a GUI.
You can ignore single files by executing this in the containing directory:
svn propset svn:ignore filename .
Replace filename by the filename you want to ignore. This can also be a wildcard expression like *.suo. It can also be a directory like tmp.
you can define the prop svn:ignore
so in your directory where you want ignore file made :
svn propedit svn:ignore .
An editor is open an add your information into. Close it and your file are ignore
