I have this snippet.
SELECT 'SELECT * FROM ' + OBJECT_SCHEMA_NAME(o.object_id, DB_ID(${20:})) + '.' + name,
*
FROM ${20/$/./}sys.all_objects o
WHERE name LIKE '%${10:hadr}%'
ORDER BY o.name;
And this is how it works:
When the user types something in the function DB_ID(), I hope the content the user typed appears before sys.all_objects AND append an additional .. It already works like this as it shown in the above gif. However, I also hope if the user types nothing in the function DB_ID(), don't add . before sys.all_objects. Is this possible?
No need to add the : in field 2:
DB_ID(${2})
Use field 2
${2/(.*)/$1${1:+.}/}
capture all the typed text: (.*)
replace it with all the typed text: $1
followed by a . if the typed text is not empty: ${1:+.}
You can use lookbehind to assert that there's something in that field: (?<=.)$. For a minimal example, let's say this is the original snippet:
foo($1); ${1/$/./}bar()
Change it to:
foo($1); ${1/(?<=.)$/./}bar()
If I type something, e.g. x, then press Tab, I get:
foo(x); x.bar()
If I don't type anything then press Tab, I get:
foo(); bar()

I would like to define a snippet for comments like
//************
//* foo A1 *
//************
where I enter foo A1 and it would create a line with (6+ len(${1}) asterisks etc. - is that doable and if so, how?
While I am a big proponent of HyperSnips (see
[VSCODE]: Is there a way to insert N times the same characters,
VS Code: how to make a python snippet that after string or expression hitting tab will transform it and
VSCode Advanced Custom Snippets for how to use it),
it is instructive to see how to do this with just the built-in snippet functionality in vscode. Here is a snippet that does what you want:
"Custom Comment": {
"prefix": ["cc2"], // whatever trigger you want, then tab, write your info and tab again
"body": [
"//***${1/./*/g}***",
"//* $1 *",
"//***${1/./*/g}***"
]
},
That just adds 3 asterisks to the beginning and 3 to the end of your added comment, each character of which is replaced by an asterisk as well.
You can use the extension HyperSnips
snippet comment "Comment" A
``rv = '//' + '*'.repeat(t[0].length + 6)``
//* $1 *
``rv = '//' + '*'.repeat(t[0].length + 6)``

my #para_text = $mech->xpath('/html/body/form/table/tbody/tr[2]/td[3]/table/tbody/tr[2]/td/table/tbody/tr[3]/td/div/div/div', type => $mech->xpathResult('STRING_TYPE'));
#BELOW IS JUST TO MAKE SURE THE ABOVE CAPTURED THE CORRECT TEXT
print "Look here: #para_text";
$mech->click_button( id => "lnkHdrreplyall");
$mech->eval_in_page('document.getElementsByName("txtbdy")[0].value = "#para_text"');
In the last line of my code I need to put the contents of the #para_text array as the text to output into a text box on a website however from the "document" till the end of the line it needs to be surrounded by ' ' to work. Obviously this doesnt allow interpolation as that would require " " Any ideas on what to do?
To define a string that itself contains double quotes as well as interpolating variable values, you may use the alternative form of the double quote qq/ ... /, where you can choose the delimiter yourself and prevent the double quote " from being special
So you can write
$mech->eval_in_page(qq/document.getElementsByName("txtbdy")[0].value = "#para_text"/)
Accept a customer number and then output the details of each order and items to an editor widget.
Display them in the editor widget ( editor-1 as object name).
define temp-table ttcustomer
field custnum like customer.cust-num
field cname like customer.name
field orders like order.order-num
field items like item.item-num
field itemname like item.item-name .
find first customer WHERE customer.cust-num = input f1 NO-LOCK .
create ttcustomer .
assign
ttcustomer.custnum = customer.cust-num
ttcustomer.cname = customer.name.
for each order WHERE Order.cust-num = input f1 NO-LOCK .
assign
ttcustomer.orders = order.order-num.
for each order-line where order-line.order-num = order.order-num no-lock.
for each item where item.item-num = order-line.item-num no-lock.
assign
ttcustomer.items = item.item-num
ttcustomer.itemname = item.item-name.
end.
end.
end.
I have no idea why you would want to display that on an editor. So I'll assume you want to concatenate the info you gathered in the for each loop into an editor.
So after the last end, you could do this:
define variable editor-1 as character view-as editor.
for each ttcustomer:
assign editor-1 = editor-1 + ttcustomer.items + ' ' + ttcustomer.itemname + chr(13).
end.
display editor-1.
If chr(13) doesn't work to skip a line, try chr(10).
PS: An editor is really probably not the widget you want to display this. I'd use a browse. But since the question asks for an editor, there.
PS2: You didn't assign the other fields you put on the temp-table, so I'm not displaying them. But it's just a matter of adding them to the assign line above, not forgetting the spaces, dashes or whatever you'd like to use as a separator.
Help My Balloon finding macro is not working with input box, it works only when i manually add the balloon number.. please tell me what i m missing ...Ferdo m expecting you
Language="VBSCRIPT"
Sub CATMain()
Set drawingDocument1 = CATIA.ActiveDocument
Set selection1 = drawingDocument1.Selection
result = InputBox("Ballon Number ?", "Title") 'The variable is assigned the value entered in the InputBox
selection1.Search "CATDrwSearch.DrwBalloon.BalloonPartName_CAP= result ,all"
End Sub
I don't know what you are doing but the last line looks wrong. I don't know what the docs are for your function but you are passing the string result rather than the value of the variable result because it is in quotes. Assuming your line is otherwise right ...
selection1.Search "CATDrwSearch.DrwBalloon.BalloonPartName_CAP= " & result & ",all"
I have a simple rule in ANTLR:
title returns [ElementVector<Element> v]
#init{
$v = new ElementVector<Element>() ;
}
: '[]'
| '[' title_args {$v.add($title_args.ele);} (',' title_args {$v = $title_args.ele ;})* ']'
;
with title_args being:
title_args returns [Element ele]
: author {$ele = new Element("author", $author.text); }
| location {$ele = new Element("location", $location.text); }
;
Trying to compile that I get confronted with a 127 error in the title rule: title_args is a non-unique reference.
I've followed the solution given to another similar question in this website (How to deal with list return values in ANTLR) however it only seems to work with lexical rules.
Is there a specific way to go around it ?
Thank you,
Christos
You have 2 title_args in your expression, you need to alias them. Try this:
| '[' t1=title_args {$v.add($t1.ele);} (',' t2=title_args {$v = $t2.ele ;})* ']'
t1 and t2 are arbitrary aliases you can choose anything you want as long as they match up.
I think the problem is your reusing the title_args var. Try changing one of those variable names.
Yeah, I had the same problem.
You need to change one of the variable names; for example, do like the following:
title_args
title_args1
in your code instead of using title_args twice.
If title_args is a parser rule, then just create the same rule with the name title_args1.
So, basically there would be two rules with the same functionality.
