I'd like to be able to hit a shortcut like cmd-shift-r and have that automatically run a bash command, say, mix test test/turtle/api/v3_test.exs:72.
In other words: mix test {FILE_ACTIVE}:{FILE_ACTIVE_LINE_NUMBER}
What is the best way to accomplish this? Is there an atom package that takes care of this or something I could write quickly myself?
Thanks!
There is a fairly low-fi way to get this to work using your init.coffee load this by going to File → Init Script... or by choosing Application: Open Your Init Script from the Command Palette.
Add the following to the bottom of your init.coffee:
atom.commands.add 'atom-text-editor',
'custom:execute-this-test': ->
if editor = atom.workspace.getActiveTextEditor()
row = editor.getCursors()[0].getBufferRow() + 1
path = editor.buffer.file.path
{spawn} = require 'child_process'
mix = spawn 'mix', ['test', "#{path}:#{row}"]
mix.stderr.on 'data', (data) ->
atom.notifications.addError data.toString()
mix.stdout.on 'data', (data) ->
atom.notifications.addInfo data.toString()
mix.on 'exit', (code) ->
atom.notifications.addInfo "Exited with Code #{code}"
Save the file with Ctrl-S and reload the text editor with Ctrl-Alt-R.
Once Atom has restarted, find the line in the file you want to execute the code against and open the Command Palette with Ctrl-Shift-P and search for Execute This Test.
You may want to tweak the code to be reduce the amount of output it generates, however the above is probably enough to get you started. If you wanted to optimize the workflow even further you can create a Keybinding.

In OpenMDAO V3.1 I am using an ExternalCodeComp to execute a CFD code. Typically, I would call it as such:
mpirun nodet_mpi --design_run
If the above call is made in the appropriate directory, then it will find the appropriate run file and execute the CFD run. I have tried command args for the ExternalCodeComp;
execute = ['mpirun', 'nodet_mpi', '--design_run']
execute = ['mpirun', 'nodet_mpi --design_run']
execute = ['mpirun nodet_mpi --design_run']
I either get an error such as:
RunTimeError: 255, execvp error on file "nodet_mpi --design_run" (No such file or directory)
Or that the command cannot be found.
Is there any way to setup the execute statement to include commandline args for the flow solver when an input file is not defined?
Thanks in advance!
One detail in your question seems incorrect, you state that you have tried execute = "...". The ExternalCodeComp uses an option called command. I will assume that you are using the correct option in your code.
The most correct form to use is the list with all arguments as single entries in the list:
self.options['command'] = ['mpirun', 'nodet_mpi', '--design_run']
Your error msg seems to indicate that the directory that OpenMDAO is running in is not the same as the directory you would like to execute the CFD code from. The absolute simplest solution would be to make sure that you are in the correct directory via cd in the terminal window before executing your python script.
However, there is likely a reason that your python script is in a different place so there are other options I can suggest:
You can use a combination of os.getcwd() and os.chdir() inside the compute method that you have implemented to make sure you switch into and out of the working directory for the CFD code.
If you would like to, you can modify the entries of the list you've assigned to the self.options['command'] option on the fly within your compute method. You would again be relying on some of the methods in the os module for help. os.path.exists can be used to test if the specific input files you need exist or not, and you can modify the command option accordingly.
For option 2, code would look something like this:
def compute(self, inputs, outputs):
if os.path.exists('some_input.file'):
self.options['command'] = ['mpirun', 'nodet_mpi', '--design_run']
else:
self.options['command'] = ['mpirun', 'nodet_mpi', '--design_run', '--other_options']
# the parent compute function actually runs the external code
super().compute(inputs, outputs)
I am attempting to design a front end GUI for a CLI program by the name of eac3to.exe. The problem as I see it is that this program sends all of it's output to a cmd window. This is giving me no end of trouble because I need to get a lot of this output into a GUI window. This sounds easy enough, but I am begining to wonder whether I have found one of AutoIt's limitations?
I can use the Run() function with a windows internal command such as Dir and then get the output into a variable with the AutoIt StdoutRead() function, but I just can't get the output from an external program such as eac3to.exe - it just doesn't seem to work whatever I do! Just for testing purposesI I don't even need to get the output to a a GUI window: just printing it with ConsoleWrite() is good enough as this proves that I was able to read it into a variable. So at this stage that's all I need to do - get the text (usually about 10 lines) that has been output to a cmd window by my external CLI program into a variable. Once I can do this the rest will be a lot easier. This is what I have been trying, but it never works:
Global $iPID = Run("C:\VIDEO_EDITING\eac3to\eac3to.exe","", #SW_SHOW)
Global $ScreenOutput = StdoutRead($iPID)
ConsoleWrite($ScreenOutput & #CRLF)
After running this script all I get from the consolWrite() is a blank line - not the text data that was output as a result of running eac3to.exe (running eac3to without any arguments just lists a screen of help text relating to all the commandline options), and that's what I am trying to get into a variable so that I can put it to use later in the program.
Before I suggest a solution let me just tell you that Autoit has one
of the best help files out there. Use it.
You are missing $STDOUT_CHILD = Provide a handle to the child's STDOUT stream.
Also, you can't just do RUN and immediately call stdoutRead. At what point did you give the app some time to do anything and actually print something back to the console?
You need to either use ProcessWaitClose and read the stream then or, you should read the stream in a loop. Simplest check would be to set a sleep between RUN and READ and see what happens.
#include <AutoItConstants.au3>
Global $iPID = Run("C:\VIDEO_EDITING\eac3to\eac3to.exe","", #SW_SHOW, $STDOUT_CHILD)
; Wait until the process has closed using the PID returned by Run.
ProcessWaitClose($iPID)
; Read the Stdout stream of the PID returned by Run. This can also be done in a while loop. Look at the example for StderrRead.
; If the proccess doesnt end when finished you need to put this inside of a loop.
Local $ScreenOutput = StdoutRead($iPID)
ConsoleWrite($ScreenOutput & #CRLF)
I want to run simple go code directly from terminal/command line. For example:
go run "
package main
func main() {
println("hello")
}
"
hello
However golang allows code execution only from file. So maybe there are some ways how to emulate it? Like this:
go run file.go < echo "...."
But there should be no files after actions above.
In command-line, only a project like go-repl would compile/run a multi-line go source code without leaving any .go file behind.
An alternative: gore:
$ gore
Enter one or more lines and hit ctrl-D
func test() string {return "hello"}
println(test())
^D
---------------------------------
hello
(Other repl-like solution are listed in "Does Go provide REPL?")
Or you would need to develop a go wrapper which would internally create a source code and go run it, before deleting it.
Ubuntu has a gorun tool which works well for small scripts. It compiles scripts on the fly, caching the binaries in /tmp.
https://wiki.ubuntu.com/gorun
Although it's intended for scripting and not as a REPL, you could use it in various ways.
Although gorun has come from the Ubuntu community, it should work on any Linux distro because it uses vanilla Go source code via
$ go get launchpad.net/gorun
I am enjoying developing inside the ipython notebook, but I am having a problem when I want to write a main() function that reads the command line args (with OptionParser, for example). I want to be able to export the code to a .py file and run it from the command line, but I haven't found a way to have a main() that runs both in the notebook with predefined arguments or from the command line with python and command line args. What is the secret?
In case that is not clear, I would like to do something like this:
if __name__ == '__main__':
# if in the notebook
vals = {'debug':True, 'tag_file': 't.tags'}
options = Object()
for k,v in vals.items():
options.setattr(k,v)
args = 'fname1.txt'
# if running as a command line python script
from optparse import OptionParser
parser = OptionParser()
parser.add_option('-d','--debug',action='store_true',dest='debug')
parser.add_option('-t','--tags',action='store',dest='tag_file')
options,args = parser.parse_args()
You cannot determine that you are in an IPython notebook or a qtconsole, or a simple IPython shell, for the simple reason the 3 can be connected to the same kernel at the same time.
It would be like asking, what color is the current key the user is typing. You could get it by looking the plugged usb devices and look for images on the internet and guess the keyboard color, but nothing guarantees you it will be accurate, nor that it won't change, and user can have multiple keyboard plugged, or even painted keyboard.
It is really the same with the notebook, Even if you determine you are in ZMQKernel, are you speeking to qtconsole or webserver ? Again, you found that you were talking to the webserver, are you talking to JS or Emacs ? And so on and so forth.
The only thing you can do, you can ask the user.
What is reliable, is test wether you are in IPython or not.
If you really but reeaaalllyy want a way, as until now, the notebook is the only thing that can display Javascript. And javascript can execute code in pyton. So you might be able to create something that display JS that send back info to the kernel. And using thread and timer you can say that you were not in a notebook (but you will have a race condition).
Don't worry about the distinction. Just set default values, and unless they are overridden from the command line, use those.
if __name__ == '__main__':
parser = OptionParser()
parser.add_option('-d', '--debug', action='store_true', dest='debug',
default=True)
parser.add_option('-t','--tags',action='store',dest='tag_file',
default='t.tags')
options, args = parser.parse_args()
if not args:
args = ['fname1.txt']
I am trying to create a key binding for "Evaluate buffer till here" in Emacs & ESS, which is situated in ESS => ESS Eval menu. Most of the commands in that menu are listed in help files (http://ess.r-project.org/Manual/ess.html, and in Emacs options), but this particular one is not. If I place following code in .emacs file:
(eval-after-load "ess-mode" '(define-key ess-mode-map (kbd "C-.") 'ess-eval-buffer-till-here))
I get a following message when trying to use the binding: Symbol´s function definition is void: ess-eval-buffer-till-here. Obviously I am calling for wrong name. What is the right name for this command and how can I see all of the commands for ESS?
So it's a menu item? Type C-hk and then select that item.
(Menus are implemented as keymaps, so this is just the normal describe-key functionality.)
You can also see the non-interactive call form of the last command with C-xESCESC or C-xM-:. It's easy to figure out the command name once you have that. (thanks event_jr)
For listing all commands, most modes will list all their key bindings in their docstring, so you can use C-hm to describe the modes in use in the buffer.
As there may be commands without bindings, you could also use M-x apropos-command to list them all (most likely specifying ^ess as a pattern, if it uses that as a consistent name space).
