Exploring ML files in Isabelle - isabelle

I was wondering if in Isabelle ML files there is a way to activate the feature that normal theory files have, i.e, you can press Ctrl+click with mouse in a definition and get the desired definition.
However, this does not seem to work for ML files. Is there any option I can activate to navigate from a function to its definition?

One way to enable the feature that you seek would be to include the ML file in a *.thy file with the command ML_file and have both of them open in jEdit. Of course, there may exist better alternatives.

Can't Use My Procedures after Loading Scheme File

I use an IDE called DrRacket to help to learn scheme.
I read a book named Simply Scheme and I downloaded the package simply-scheme so that I could run examples and do exercises in this book.
This book provides a package named functions.scm, the book instructed me to load it(functions.scm) into the interpreter so I could explore those functions and procedures inside it.
But it seems that I can't use procedures inside the file(functions.scm) after I loaded it.
This is OK when I found I could just open it(functions.scm) in IDE and click run button top right-hand corner.
However, when I kept reading this book, I wrote more and more procedures. And there are more and more times when I want to reuse my procedures defined before.
It becomes a severe problem that I can't use my procedures after loading files into scheme interpreter.
I really don't understand why would this happen. When I add extra parentheses into those files and then I loaded them into Scheme, the interpreter would show error message about unmatched parentheses. This means the interpreter does read the loading files. But why can't I just use the procedures I defined inside it?
I would appreciate it if there is anyone who could explain it and give me a solution to this issue.

Is it possible to use the same key-binding for two different packages based on the file extension?

I use the atom-runner package, which runs scripts when I click alt+x:
Now, I also installed the gpp-compiler package, which runs c++ files when I click F5:
It is confusing to have two different key-bindings for running. I would like to use alt+x both for gpp-compiler and for atom-runner, based on the file: if it's a c/c++ file then run gpp-compiler, otherwise run atom-runner.
Is this possible?
You are in luck. I was doing something similar to this recently and thought that this could be done.
I've made an Atom package to do what you're looking for. You can find it at https://atom.io/packages/multi-hotkey. The default hotkey is Ctrl-M.
Currently only one hotkey is possible, but with customization available for four different user-inputted file extensions and corresponding commands, and a final command for anything not matching the preceding extensions.

How to rename the .mcs output file when synthesizing a design with Xilinx ISE

When I synthesize a design using Xilinx ISE, the output file is named untitled.mcs. I would like to configure the project to use an output filename more appropriate to the project I am synthesizing.
I have examined all the properties easily reachable by right clicking the the implementation panel in the tool, but I can't find a configuration option to change output file names. I have also searched the help, but couldn't find anything useful. Can anyone suggest where I need to configure the output filename or tell me where or what to search?
I am aware of at least two things I could be doing wrong and would appreciate comments. First, I am not using TCL to synthesize my project. I just right click in the implementation panel and choose run. Perhaps if I create a TCL script to I would have finer control or output file naming. Second, I can see several files named untitled.x where x is [cfi|mcs|prm|sig]. I guess these are a sequence of files processed from one format to another, and if I understood the process, I could configure the name of the first and see all the derived files change their names to follow.
The answer to my question is that you don't use ISE to configure output PROM file names, you do it in the iMPACT tool. When it is properly configured, ISE will run iMPACT to create the programming file.
If anyone needs the precise details on configuring iMPACT, the built in help has the details. See the section entitled "Creating Xilinx Flash/PROM Files". During the setup of the programming file, you get to choose the output file name.
One extra pointer from me: The help says you double click to open a wizard. For me that didn't work, but there is an icon (or tool bar button) to launch the PROM file formatter wizard when Create PROM File is highlighted in the iMPACT Flows panel.
When you have created an saved an iMPACT project file, you select it in ISE and ISE will create a PROM programming file at the last step of the synthesize process.

Anyone know how to set Notepad++ as default text editor for SAS, Stata and R?

Anyone know how to set Notepad++ as default text editor for SAS, Stata and R?
I'm having the hardest time finding anything online (particularly for SAS). Looking for ability to run code from Notepad++ as well as setup color coding.
Thanks.
Why not just go the GUI route: right click, e.g., any foo.R file and select "Open with...", then pick Np++ and click the "always open this file type.." button. Rinse, lather, repeat.
BTW, for R, if you don't already have it, get "NppToR" , a little app which lets you execute code directly from the Npp window.
On windows you can either:
manually edit the keys for the file type to set the value of HKEY_CLASSES_ROOT\FILE_TYPE\shell\edit\command where FILE_TYPE is the appropriate one for each of the files extensions you wish to change this is quite hard work or
you can use a program that does it for you such as the free Default Programs Editor
In either case the first thing to do is to back up the registry.
I would seriously suggest looking into using one of the many, some free IDEs as they will automatically include the run from edit environment, syntax highlighting, code completion and, in many cases, debugging as well.
Notepad++ is my favorite editor and I was in the same shoes as you are now.
I am assuming that you are in Windows (Notepad ++ doesn't exist in Mac, saddest thing for me)
Please follow the steps mentioned in the below webpage and do as the author says.

Now for in-line editing , it may be not be the best choice for SAS. Although I haven't tried it much so not a good person to comment on it.

Closure: --namespace Foo does not include Foo.Bar, and related issues

I have a rather big library with a significant set of APIs that I need to expose. In fact, I'd like to expose the whole thing. There is a lot of namespacing going on, like:
FooLibrary.Bar
FooLibrary.Qux.Rumps
FooLibrary.Qux.Scrooge
..
Basically, what I would like to do is make sure that the user can access that whole namespace. I have had a whole bunch of trouble with this, and I'm totally new to closure, so I thought I'd ask for some input.
First, I need closurebuilder.py to send the full list of files to the closure compiler. This doesn't seem supported: --namespace Foo does not include Foo.Bar. --input only allows a single file, not a directory. Nor can I simply send my list of files to the closure compiler directly, because my code is also requiring things like "goog.assers", so I do need the resolver.
In fact, the only solution I can see is having a FooLibrary.ExposeAPI JS file that #require's everything. Surely that can't be right?
This is my main issue.
However, later the closure compiler, with ADVANCED_OPTIMIZATIONS on, will optimize all these names away. Now I can fix that by adding "#export" all over the place, which I am not happy about, but should work. I suppose it would also be valid to use an extern here. Or I could simply disable advanced optimizations.
What I can't do, apparently, is say "export FooLibrary.*". Wouldn't that make sense?
Finally, for working in source mode, I need to do goog.require() for every namespace I am using. This is merely an inconvenience, though I am mentioning because it sort of related to my trouble above. I would prefer to be able to do:
goog.requireRecursively('FooLibrary')
in order to pull all the child namespaces as well; thus, recreating with a single command the environment that I have when I am using the compiled version of my library.
I feel like I am possibly misunderstanding some things, or how Closure is supposed to be used. I'd be interested in looking at other Closure-based libraries to see how they solve this.
You are discovering that Closure-compiler is built more for the end consumer and not as much for the library author.
If you are exporting basically everything, then you would be better off with SIMPLE_OPTIMIZATIONS. I would still highly encourage you to maintain compatibility of your library with ADVANCED_OPTIMIZATIONS so that users can compile the library source with their project.
First, I need closurebuilder.py to send the full list of files to the closure compiler. ...
In fact, the only solution I can see is having a FooLibrary.ExposeAPI JS file that #require's everything. Surely that can't be right?
You would need to specify an --root of your source folder and specify the namespaces of the leaf nodes of your file dependency tree. You may have better luck with the now deprecated CalcDeps.py script. I still use it for some projects.
What I can't do, apparently, is say "export FooLibrary.*". Wouldn't that make sense?
You can't do that because it only makes sense based on the final usage. You as the library writer wish to export everything, but perhaps a consumer of your library wishes to include the source (uncompiled) version and have more dead code elimination. Library authors are stuck in a kind of middle ground between SIMPLE and ADVANCED optimization levels.
What I have done for this case is maintain a separate exports file for my namespace that exports everything. When compiling a standalone version of my library for distribution, the exports file is included in the compilation. However I can still include the library source (without the exports) into a project and get full dead code elimination. The work/payoff balance of this though must be weighed against just using SIMPLE_OPTIMIZATIONS for the standalone library.
My GeolocationMarker library has an example of this strategy.
