Basically I need to populate a column with created new words in this format (??P??P) or (??K??K), "?" is wildcard. If possible I would want the 2nd and 5th letters to be vowels. I also want to be able to change the expression (??P??P) to (??X??X), X can be any letter. I tried finding commands for this in "customise menu" and in the "insert menu" options. I tried to find expressions for this in "Regex command" documentation in Libreoffice documentation. I am not a technical person, so I do not have the ability to create scripts for this. Any help is appreciated.
Such "words" are not difficult to generate. To get a random integer use the RANDBETWEEN() function
Now, using the CODE() function, find out the code for the letter "A", add a random number from 0 to 25 to this code, and convert it back to a letter using the CHAR() function:
=CHAR(CODE("A")+RANDBETWEEN(0;25))
This will give you one random letter.
To get a random vowel letter (or any letter from a predefined list) list all the desired letters in one line and pull out one random letter using the MID() function
=MID("AEIOU";RANDBETWEEN(1;5);1)
Letters that should remain unchanged in the template, specify explicitly - just put the letter in quotation marks: "P", "K", "X"
Now you have all the necessary parts for the formula, connect them using the CONCAT() function or just using the ampersand sign &
=CHAR(CODE("A")+RANDBETWEEN(0;25)) & MID("AEIOU";RANDBETWEEN(1;5);1) & "P" & CHAR(CODE("A")+RANDBETWEEN(0;25)) & MID("AEIOU";RANDBETWEEN(1;5);1) & "P"

In Julia it is possible to add Unicode characters with LaTeX like syntax. All allowed unicode characters can be found here. For example, it is possible to add a right arrow over a character with this simple code
F\vec[TAB]
and it produces the following character
But I couldn't find a syntax to add the same right arrow over a whole word as \vec seems to always add the arrow over the previous character and does not allow to group them. For example
force\vec[TAB]
produces
Does the syntax for this feature exists ?
I want to search strings like "number 1" or "number 152" or "number 36985".
In all above strings "number " will be constant but digits will change and can have any length.
I tried Search option using wildcard but it doesn't seem to work.
basic regEx operators like + seem to not work.
I tried 'number*[1-9]*' and 'number*[1-9]+' but no luck.
This regular expression only selects upto one digit. e.g. If the string is 'number 12345' it only matches number 12345 (the part which is in bold).
Does anyone know how to do this?
Word doesn't use regular expressions in its search (Find) functionality. It has its own set of wildcard rules. These are very similar to RegEx, but not identical and not as powerful.
Using Word's wildcards, the search text below locates the examples given in the question. (Note that the semicolon separator in 1;100 may be soemthing else, depending on the list separator set in Windows (or on the Mac). My European locale uses a semicolon; the United States would use a comma, for example.
"number [0-9]{1;100}"
The 100 is an arbitrary number I chose for the maximum number of repeats of the search term just before it. Depending on how long you expect a number to be, this can be much smaller...
The logic of the search text is: number is a literal; the valid range of characters following the literal are 0 through 9; there may be one to one hundred of these characters - anything in that range is a match.
The only way RegEx can be used in Word is to extract a string and run the search on the string. But this dissociates the string from the document, meaning Word-specific content (formatting, fields, etc.) will be lost.
Try putting < and > on the ends of your search string to indicate the beginning and ending of the desired strings. This works for me: '<number [1-9]*>'. So does '<number [1-9]#>' which is probably what you want. Note that in Word wildcards the # is used where + is used in other RegEx systems.
I'm currently working with postgresql, I learned about this function btrim, I checked many websites for explanation, but I don't really understand.
Here they mention this example:
btrim('xyxtrimyyx', 'xyz')
It gives trim.
When I try this example:
btrim('xyxtrimyyx', 'yzz')
or
btrim('xyxtrimyyx', 'y')
I get this: xyxtrimyyx
I don't understand this. Why didn't it remove the y?
From the docs you point to, the definition says:
Remove the longest string consisting only of characters in characters
(a space by default) from the start and end of string
The reason your example doesn't work is because the function tries to strip the text from Both sides of the text, consisting only of the characters specified
Lets take a look at the first example (from the docs):
btrim('xyxtrimyyx', 'xyz')
This returns trim, because it goes through xyxtrimyyx and gets up to the t and doesn't see that letter in xyz, so that is where the function stops stripping from the front.
We are now left with trimyyx
Now we do the same, but from the end of the string.
While one of xyz is the last letter, remove that letter.
We do this until m, so we are left with trim.
Note: I have never worked with any form of sql. I could be wrong about the exact way that postgresql does this, But I am fairly certain from the docs that this is how it is done.
I have to create a procedure with same parameters names as excel columns. Some loook like this 'xxx/xxx' or 'xxx - xxx'. Is there any work around to name parameteres in a stored procedure like this?
Forward slash (/) or dash (-) are not allowed in variable names
According to http://msdn.microsoft.com/en-us/library/ms175874.aspx, that means that the allowed characters are:
Letters as defined in the Unicode Standard 3.2. The Unicode
definition of letters includes Latin characters from a through z,
from A through Z, and also letter characters from other languages.
Decimal numbers from either Basic Latin or other national scripts.
The at sign (#), dollar sign ($), number sign (#), or underscore (_).
Okay first of all why would you ever want to use special characters? That is like saying I want to fry toast underwater with electricity, why can't I have an outlet to allow that? Special characters denote special things and as such many engines, not just in SQL, but most languages will not allow reserved characters for use in variables. The best you could do was put in parameters with the reversed '_' and then replace that AFTER the object was already created for echoing out. The placeholder name of '#(something)' is really arbitrary and could be #X or #LookAtMe. It's type is important to form a contract that must be fulfilled for execution but the naming is really for hooking up. Having said that if you just must have these weird names echoed out you could do something like this:
CREATE PROC pSimpleParam #My_Param INT
AS
SELECT #My_Param
GO
ALTER PROC pSimpleParam #My_Param INT
AS
SELECT
pr.name AS ParameterName
, REPLACE(pr.name, '_', '-') AS AlteredParameterName
FROM sys.procedures p
INNER JOIN sys.parameters pr ON pr.object_id = p.object_id
AND p.name = 'pSimpleParam'
GO
I've prepared a macro in Notepad++ to transform a ldif file in a csv file with a few fields. Everything is OK but I have a final problem: I have to have 2 fields with a specific length and in this moment I cannot ensure that length because in the source file they are not coming so
For instance, I generate this line:
12345,namenamename,123456
And I have to ensure that the 2nd and 3rd fields have 30 (filling with spaces at right side) and 9 (filling with zeros at left) characters, so in this case I should generate:
12345,namenamename ,000123456
I haven't found how Notepad++ could match a pattern in order to add spaces/zeros, so I have though in to add 1 space/zero to the proper field and repeat this step so many times as needed to ensure the lengths (this is, 29 and 8, because they cannot come empty) and search with the length in the regex (for instance: \d{1,8} for the third field)
My question is: can I repeat only one step of the macro several times (and the rest of the macro only 1 repetition)?
I've read the wiki related to this point (http://sourceforge.net/apps/mediawiki/notepad-plus/index.php?title=Editing_Configuration_Files#.3CMacros.3E) and I don't found anything neither
If not possible, how could be a good solution? Create another 2 different macros and after execute the main one, execute this new 2 macros several times?
Thanks in advance!
A two pass solution with Notepad++ is possible. Find a pair of characters or two short sequence of characters that never occurs in your data file. I will use =#<= and =>#= here.
First pass, generate or convert the input text into the form 12345,=#<=namenamename______________________________,000000000123456=>#=. Ie add 30 spaces after the name and nine zeroes before the number (underscores used here just to make things clearer).
Second pass, do a regular expression search for =#<=(.{30})_*,0*(\d{9})=>#= and replace with \1,\2.
I have just suggested a similar solution in special timestamp format of csv
