I wanted to write a script that required a filename as an argument.
I wanted to leverage 'ido-find-file' to get the file, since it's such
a nice way to select a filename, but I didn't want to open the file
as such, just use it as the argument to my function.
ido-find-file internally uses ido-read-file-name to ask for the file path in the minibuffer.
You can use it like this:
(ido-read-file-name "my prompt: ")
Just use read-file-name. This will use IDO's method if IDO is enabled (i.e. if the user likes IDO) and will use another method if the user prefers the other method.

As soon as I try to access a folder/file containing an emoji in its name from my Lua 5.2 script, for example like this:
os.execute('start "" "' .. path .. "\\scripts\\menu\\đź“„ My Scripts" .. '"')
The Windows' Command Prompt simply refuses to open it with the following error message:
I'm aware Windows' Command Prompt doesn't support emojis and therefore is not possible to make it work just like that, but my doubt is if won't exist some workaround or whatever I can do to ensure any Windows/Unix user is going to able to get the folder open by my Lua script without any problem.
I have tried i.e. things like use the codes instead (1246 and U+1F4F0 in this page facing up case) without success. Couldn't I for example simply use some kind of "wildcard" instead? I mean, knowing it's always going to be the very first character in the name. Or, well, any other ideas will be welcomed, cause nothing I'm trying really seems to work...
Of course if it's going to represent any problem I'll simply refuse to use them, but it came in handy for some "first sight" folder distinction and, if possible, I'd like to can count this little visual resource 🙄
This is a Problem about how the string is constructed.
I found only one solution with [[command "path"]] (on Windows 11 and Lua 5.3)...
os.execute([[start ]] .. path .. [["\scripts\menu\đź“„ My Scripts"]])
-- My Testpath is/was: os.execute([[dir "%localappdata%\nvim\đź“„ Lua"]])
...the long string ([[]]) will not be interpreted (coercionated) by Lua.
That also have the side effect that you can use single backslashs with that kind of string.
Environment variable expansion (e.g. Windows: %localappdata%) only works inside doublequotes.
Single quotes instead ([[command '%localappdate%\path\']]) will not work (expanded).
os.execute accepts only ANSI-encoded strings (win-1252 in European Windows), but it is unable to encode an emoji.
Hint: you can create .bat-file to do the task for you and invoke it from Lua with os.execute.
Is there a way to load an applescript library based on a variable.
What I try to achieve is this:
set basescript to "hello.scpt"
tell script basescript
dialoger("testing")
end tell
the basescript will contain something like:
on dialoger(message)
display dialog message
end dialoger
This works fine a long as I type it out but as soon I try to pass it like a var it keeps giving errors...
Any help would be greatly appreciated
I use script libraries all the time. Once you get the hang of it, it becomes a huge timesaver. There are a couple of ways of loading script commands from a “Library Script” into another script.
One way is to use the load script command by setting a variable name to load script and path/to/script.
There is also another way, which in my opinion, is much more powerful. You can import library scripts using the use statement. This method removes the need of using tell statements.
For example, I saved your following code as “Hello.scpt” in my /Users/YOUR SHORT NAME/Library/Script Libraries/ folder.
on dialoger(message)
display dialog message
end dialoger
Next, in the script in which I want to load the commands from the Library script “Hello.scpt”, this is the code I used using the use statement
use basescript : script "Hello"
use scripting additions
basescript's dialoger("testing")
By using use statements with multiple applications, you can combine terms from different sources in ways impossible using standard tell statements or tell blocks, because the tell construct only makes one terminology source available at a time.
Solution:
If you do set basescript to load script POSIX file "/path/to/Hello.scpt" then tell basescript to dialoger("testing") will work!
Assuming that these are script libraries, you can accomplish what you want using a handler like so:
-- send the same of the script library in the first parameter
-- and the message in the second
myHandler("hello", "My Message")
on myHandler(libName, message)
tell script libName
dialoger(message)
end tell
end test
Since the handler isn't processed until runtime, it will dynamically implement the correct script library passed in libName.
Is there any way of adding "helper" methods to the mongo shell that loads each time you use it?
Basically whenever you want to query by _id, you have to do something like this.
db.collectionName.findOne({_id: ObjectId('THIS-IS-AN-OBJECTID')})
Whenever I'm going to be doing a lot of command line commands, I alias the ObjectId function to make it easier to type.
var ob = ObjectId;
db.collectionName.findOne({_id: ob('AN-OBJECTID')})
db.collectionName.findOne({_id: ob('ANOTHER-ONE')})
db.collectionName.findOne({_id: ob('ANOTHER')})
It would be pretty chill if there was a way of either running a specified piece of JS / add a chunk of code that runs each time mongo is pulled up from the shell. I checked out MongoDB's CLI documentation, but didn't see anything like that available, so I figured I would ask here.
I know there is a possibility of using this nefariously, so this might be a situation where it might be unsupported by the mongo shell by default. This might be a situation where we can create a helper bash script of some sort to launch the shell, then inject keyboard input to create the helper ob function? Not sure how this could be tackled personally, but would love some insight on how to do something like this, either natively or through a helper script of some sort.
If you want code to execute every time you launch the shell, then whatever you place in .mongorc.js will be run on launch:
.mongorc.js File
When starting, mongo checks the user’s HOME directory for a JavaScript file named .mongorc.js. If found, mongo interprets the content of .mongorc.js before displaying the prompt for the first time. If you use the shell to evaluate a JavaScript file or expression, either by using the --eval option on the command line or by specifying a .js file to mongo, mongo will read the .mongorc.js file after the JavaScript has finished processing. You can prevent .mongorc.js from being loaded by using the --norc option.
So simply define your variable association there.
You could also supply a file of your choice along with the --shell option to let the command know you want the shell opened on completion of any instructions contained:
mongo --shell file_with_javascript.js
But as mentioned, the .mongorc.js file would still be called (if present) unless the --norc option was also specified.
I write a lot of Rails apps these days and would like to have vim add header comments to all the code I work on..
I tend to store my projects in
~/Development/Repos/Personal
And
~/Development/Repos/Work
Can I get vim to use different copyrights etc based on where abouts the file is being created?
You can just save a header template as a plain text file and read it into a new file with :read. As for checking the path, just write a Ruby script to produce the desired text and invoke it with :read!. Creating a true vim plugin is also an option. However, why waste time learning a new language and API when you already know how to deal with text and paths in Ruby? Although, a bash script would create even less friction if you are comfortable with it.
I suggest you to use one of the many snippet plugins, like XPTemplate or snipMate, to create a 'header' snippet and then use it. The force of these plugins is that you just have to type a word and then press tab to get the expanded snippet.
Here's a snippet from my vimrc which puts in boilerplate when I create a file named test_something.rb. You can probably use a similar autocmd to conditionally add the copyright you desire. You may have to check for the expanded path in the function, but it seems doable with some vimscripting.
" Autocommands
autocmd BufNewFile *test*.rb call MakeRubyUnitTester()
"
" Functions
" Fill in the boilerplate for Ruby Unit Tests
function! MakeRubyUnitTester()
exec "normal irequire 'test/unit'
class TC_Simple < Test::Unit::TestCase"
endfunction
I've got a situation where I need to alter the contents of a cached file based off of one of the query string arguments passed in. I'd love to use sed to do a simple regular expression replacement of a value based off of said argument but I can't figure that one out. I could use a ruby script to do the replacement for me but can't seem to access the query string for the request within the script. The documents for mod_ext_filter say:
In addition to the standard CGI environment variables, DOCUMENT_URI, DOCUMENT_PATH_INFO, and QUERY_STRING_UNESCAPED will also be set for the program.
Um yeah, can't seem to access those.
Has anybody any experience with this or does anybody have a better solution?
Doh! Looks like I simply need to access the ENV variable within ruby. Pretty dumb of me.
Using PHP scripting language server function we can able to get the query string values.
echo $_SERVER['REQUEST_URI'];
And pass the URL arguments as a variable to the file and make it dynamic.
