I am using diff -urN to compare two directories and create a patch, something like:
diff -urN ../resources-original/ogc ogc > ../../../src/main/patches/ogc.patch
The patch contains dates in --- and +++ lines:
--- ../resources-original/ogc/wms/1.3.0/capabilities_1_3_0.xsd Sun Jul 22 03:59:38 2012
+++ ogc/wms/1.3.0/capabilities_1_3_0.xsd Sun Jun 12 19:59:29 2016
Is there a possibility to suppress these dates?
Maybe something like
awk '/^(---|\+\+\+)/ { sub(" " $(NF-5) " " $(NF-4) " " $(NF-3) " " $(NF-2) " "$(NF-1) " " $NF, " Thu Jan 1 00:00:00 1970") }1'

Is there any formula that I can use to show up each month according to start & end date in spreadsheet.
Example:
Start Date:2022-07-22
End Date:2022-10-22
I expected formula to extract value something like this
Jul - Aug - Sep - Oct
I've tried formula
=IF(A2="","",IF(TEXT(B2,"MM")-TEXT(A2,"MM")>1,CONCATENATE(TEXT(A2,"MMM")&" - "&text(EDATE(A2,1),"MMM")&" - "&TEXT(B2,"MMM")),IF(TEXT(A2,"MMM")=TEXT(B2,"MMM"),TEXT(A2,"MMM"),CONCATENATE(TEXT(A2,"MMM")&" - "&TEXT(B2,"MMM"))))) but it only give me correct value if there is up to 3 month period between start & end date.
Here's a link to the sample spreadsheet
For single cell can try-
=JOIN("-",UNIQUE(INDEX(TEXT(SEQUENCE(B2-A2+1,1,A2),"mmm"))))
For spill array-
=BYROW(A2:INDEX(B2:B,MATCH(9^9,B2:B)),LAMBDA(x,JOIN("-",UNIQUE(INDEX(TEXT(SEQUENCE(INDEX(x,2)-INDEX(x,1)+1,1,INDEX(x,1)),"mmm"))))))
See your sheet.
Get the difference in dates in months using DATEDIF and get dates in each intervening month using EOMONTH+SEQUENCE and convert the end of month dates to TEXT:
Start Date
End Date
Months
2022-07-01
2022-10-30
Jul - Aug - Sep - Oct
2022-08-02
2022-08-31
Aug
2022-07-03
2022-11-01
Jul - Aug - Sep - Oct - Nov
Drag fill formula:
=ARRAYFORMULA(JOIN(" - ",TEXT(EOMONTH(A2,SEQUENCE(DATEDIF(A2,EOMONTH(B2,),"M")+1)-1),"mmm")))
Or as a self adjusting array formula:
=MAP(A2:INDEX(A:A,COUNTA(A:A)),LAMBDA(a, ARRAYFORMULA(JOIN(" - ",TEXT(EOMONTH(a,SEQUENCE(DATEDIF(a,EOMONTH(OFFSET(a,0,1),),"M")+1)-1),"mmm")))))
This should be faster and efficient than getting all the dates and filtering them out one by one, thereby reducing space and time complexity.
Use sequence(), edate() and join(), like this:
=arrayformula( map(
A2:A, B2:B,
lambda(
start, end,
if(
isdate(start) * isdate(end),
join(
" - ",
text(
edate(
start,
sequence(
12 * (year(end) - year(start)) + month(end) - month(start) + 1,
1, 0
)
),
"MMM"
)
),
iferror(1/0)
)
)
) )
I have some saved dates in JavaScript using new Date() that looks like:
"Sun Feb 24 2019 14:44:20 GMT+0200 (Eastern European Standard Time)"
I'm trying to parse these to Elixir DateTime; I didn't find anything in "timex" that can help and I already know that I can use DateTime.from_iso8601 but for dates saved using new Date().toISOString() but what i need is to parse the above string.
Thanks in advance
You can use elixir binary pattern matching to extract the date parts and parse using Timex's RFC1123 format. The RFC1123 is the format e.g Tue, 05 Mar 2013 23:25:19 +0200. Run h Timex.Format.DateTime.Formatters.Default in iex to see other formats.
iex> date_string = "Sun Feb 24 2019 14:44:20 GMT+0200 (Eastern European Standard Time)"
iex> <<day_name::binary-3,_,month_name::binary-3,_,day::binary-2,_,year::binary-4,_,time::binary-8,_::binary-4,offset::binary-5,_,rest::binary>> = date_string
iex> Timex.parse("#{day_name}, #{day} #{month_name} #{year} #{time} #{offset}", "{RFC1123}")
iex> {:ok, #DateTime<2019-02-24 14:44:20+02:00 +02 Etc/GMT-2>}
Pattern matching:
The binary-size are in byte sizes. 1 byte == 1 character. For instance to get
3-character day_name the size is 3. Underscores (_) is used to pattern match the spaces in the date format
Updated answer to use binary-size rather than bitstring-size for simplicity
I didn't find anything in "timex" that can help
The Timex Parsing docs say that you can use strftime sequences, e.g %H:%M:%S, for parsing. Here's a list of strftime characters and what they match.
Here's a format string that I think should work on javascript Dates:
def parse_js_date() do
Timex.parse!("Sun Feb 24 2019 14:44:20 GMT+0200 (Eastern European Standard Time)",
"%a %b %d %Y %H:%M:%S GMT%z (%Z)",
:strftime)
end
Unfortunately, %Z doesn't want to match the time zone name, which causes Timex.parse!() to spit out an error. It looks like %Z in Elixir only matches one word, e.g. a timezone abbreviation EET. Therefore, my simple, clean solution is spoiled.
What you can do is chop off the time zone name before parsing the date string:
def parse_js_date_string() do
[date_str|_tz_name] = String.split(
"Sun Feb 24 2019 14:44:20 GMT+0200 (Eastern European Standard Time)",
" (",
parts: 2
)
Timex.parse!(date_str,
"%a %b %d %Y %H:%M:%S GMT%z",
:strftime)
end
In iex:
~/elixir_programs/my$ iex -S mix
Erlang/OTP 20 [erts-9.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]

Im trying to use [datetime]::ParseExact
The string i need to convert to datetime is Wed Jun 27 08:50:00 2018 -0500
I couldnt figure out the correct format to convert it correctly.
Please help me out. Thanks
Try this as well:
$Date = 'Wed Jun 27 08:50:00 2018 -0500'
[datetime]::ParseExact($Date,"ddd MMM dd HH:mm:ss yyyy zzz",[CultureInfo]::InvariantCulture)
There are several options. To some extent it will depend on what you want to do with that time offset. Here is one way that ignores the offset:
$test = 'Wed Jun 27 08:50:00 2018 -0500'
$parts = $test.split(' ')
$date = get-date ('{0}{1}{2} {3}' -f $parts[2], $parts[1], $parts[4], $parts[3])
I need to create a script batch, PowerShell or VB to add the day of the week to the filename.
For example, there are 4 files and all need to have MON apended to the front on Mondays, TUE on Tuesdays, WED on Wednesdays, etc.
Can anyone assist with this please?
$dow = (Get-Date -f ddd).ToUpper()
$fileName = "${dow}_your_file_name.txt "
THU_your_file_name.txt
Use the VBScript Docs or Google for details on the Weekday() and WeekdayName() functions used in:
Today = Date()
DayNum = Weekday(Today)
DayName = WeekdayName(DayNum, True)
WScript.Echo UCase(DayName) & "_" & "somefile.txt"
THU_somefile.txt
PS:
Start here: Functions (VBScript)
Well, there's an answer for powershell and one for VBScript. Here's one for Windows cmd batch.
#echo off
setlocal
for /f "tokens=5" %%I in ('find "" "%date:~0,3%" 2^>^&1') do set day=%%I
ren "oldfile.txt" "%day%_oldfile.txt"
Explanation
:: DIRECTIVE RESULT
:: --------------------------------------------------------
:: %date% Thu 02/07/2013
:: %date:~0,3% Thu
:: find "" "Thu" error stating "File not found - THU"
:: --------------------------------------------------------
Then all that remains is to redirect the error from stderr to stdout and scrape the fifth token.
(source of idea to use find to convert to upper case)
if you choose VBScript, be careful with WeekDayName function as it related to regional language settings. For example, Friday is Петък (in Bulgarian), so in my system WeekDayName with abbreviate set to True will return Пт, not Fri.
WScript.Echo WeekDayAbbrENG()
Function WeekDayAbbrENG()
Dim WDs
WDs = Split("SUN MON TUE WED THU FRI SAT")
WeekDayAbbrENG = WDs(Weekday(Now) - 1)
End Function
[EDIT] Actually, the same problem appear with Get-Date in PowerShell.
Every time I want to take a subset of a patch, I'm forced to write a script to only extract the indices that I want.
e.g. I have a patch that applies to sub directories
'yay' and 'foo'.
Is there a way to create a new patch or apply only a subset of a patch? i.e. create a new patch from the existing patch that only takes all indices that are under sub directory 'yay'. Or all indices that are not under sub directory 'foo'
If I have a patch like ( excuse the below pseudo-patch):
Index : foo/bar
yada
yada
- asdf
+ jkl
yada
yada
Index : foo/bah
blah
blah
- 28
+ 29
blah
blah
blah
Index : yay/team
go
huskies
- happy happy
+ joy joy
cougars
suck
How can I extract or apply only the 'yay' subdirectory like:
Index : yay/team
go
huskies
- happy happy
+ joy joy
cougars
suck
I know if I script up a solution I'll be re-inventing the wheel...
Take a look at the filterdiff utility, which is part of patchutils.
For example, if you have the following patch:
$ cat example.patch
diff -Naur orig/a/bar new/a/bar
--- orig/a/bar 2009-12-02 12:41:38.353745751 -0800
+++ new/a/bar 2009-12-02 12:42:17.845745951 -0800
## -1,3 +1,3 ##
4
-5
+e
6
diff -Naur orig/a/foo new/a/foo
--- orig/a/foo 2009-12-02 12:41:32.845745768 -0800
+++ new/a/foo 2009-12-02 12:42:25.697995617 -0800
## -1,3 +1,3 ##
1
2
-3
+c
diff -Naur orig/b/baz new/b/baz
--- orig/b/baz 2009-12-02 12:41:42.993745756 -0800
+++ new/b/baz 2009-12-02 12:42:37.585745735 -0800
## -1,3 +1,3 ##
-7
+z
8
9
Then you can run the following command to extract the patch for only things in the a directory like this:
$ cat example.patch | filterdiff -i 'new/a/*'
--- orig/a/bar 2009-12-02 12:41:38.353745751 -0800
+++ new/a/bar 2009-12-02 12:42:17.845745951 -0800
## -1,3 +1,3 ##
4
-5
+e
6
--- orig/a/foo 2009-12-02 12:41:32.845745768 -0800
+++ new/a/foo 2009-12-02 12:42:25.697995617 -0800
## -1,3 +1,3 ##
1
2
-3
+c
Here's my quick and dirty Perl solution.
perl -ne '#a = split /^Index :/m, join "", <>; END { for(#a) {print "Index :", $_ if (m, yay/team,)}}' < foo.patch
In response to sigjuice's request in the comments, I'm posting my script solution. It isn't 100% bullet proof, and I'll probably use filterdiff instead.
