I'm looking to insert a quote in a string, but keep everything else. So, an example string:
' "2020-10-10",8000,"Hello" '
I want to put quotes around 8000 (or whatever number is there). so:
' "2020-10-10","8000","Hello" '
How would I do that in regex?
I'm not an expert on regex but you can do it you just have to do it twice. Because I couldn't figure out a way to look for ",char or char,".
function test() {
try {
let a = ' "2020-10-10",8000,"Hello" ';
a = a.replace(/,/g,'","');
a = a.replace(/""/g,'"');
console.log(a);
}
catch(err) {
console.log(err);
}
}

7:26:23 AM Info "2020-10-10","8000","Hello"

CONFIG.CONFIG
create state file${number_of_edges} {
{interval=60
idle_interval_notification="DISABLED"}
}
create state file${number_of_edges} {
{interval=60
idle_interval_notification="DISABLED"}
}
I have file which has content like above. I want to replace ${number_of_edges} string with consecutive numbers like 0,1,2 and so on
EXPECTED OUTPUT
create state file0 {
{interval=60
idle_interval_notification="DISABLED"}
}
create state file1{
{interval=60
idle_interval_notification="DISABLED"}
}
create state file2 {
{interval=60
idle_interval_notification="DISABLED"}
}
I got the solution.
Command -
awk -vRS=edge '{$0=n$0;ORS=RT}++n' FILE
A simple awk script:
awk 'sub("\\${number_of_edges}",cnt+1, $0){cnt++}1' input.txt
Explanation:
sub("\\${number_of_edges}",cnt+1, $0) For each input line, substitute, ${number_of_edges} with variable (cnt + 1)
{cnt++} If substituted more than 0, increment variable cnt
1 output each input line

Basically here is my code and I cannot find the problem with this, So I'm looking for advice.
name = raw_input('What\'s your name? ')
if not re.match(r'[A-Za-z- ]+', name):
print 'Invalid name.\n' #error message
You must need to add end of the line anchor. Without the anchor foo? would be considered as a valid one. That is, it won't print the message Invalid name for this name.
if not re.match(r'[A-Za-z- ]+$', name):
print 'Invalid name.\n'
Example:
>>> s = 'foo?'
>>> if not re.match(r'[A-Za-z- ]+', s):
print('Invalid name.\n')
>>> if not re.match(r'[A-Za-z- ]+$', s):
print('Invalid name.\n')
Invalid name.

I have a list of items of a custom data type Film = String String Int, where the strings are the name and director and Int is the year of release.
What's the best way I would go about making a function that outputs a String or set of strings (doesn't matter how long) which show the information like:
Title: (film title) Director: (director) Released: (released)
You need to define a function that creates a String if given a Film as
an input, e.g.:
data Film = Film String String Int
instance Show Film where
show (Film t d r) =
"Title: (" ++ t ++ ") Director: (" ++ d ++ ") Released: (" ++ show(r) ++ ")"
You can read up on type classes and user-defined show here and here.

arry::utils error out, looks like some problem with the package, so that option is ruled out.

This is linked the my previous question, regex to add hypen in dates.
I would now like to be able to remove the seconds and milliseconds/change it to zero using gsub again as well
i.e. something like:
x <- c("20130603 00:00:03.102","20130703 00:01:03.103","20130804 00:03:03.104")
y <- gsub([REGEX PATTERN TO MATCH],[REPLACEMENT PATTERN TO INSERT HYPHEN and REMOVE SECONDS] ,x)
> y
[1] "2013-06-03 00:00:00" "2013-07-03 00:01:00" "2013-08-04 00:03:00"
You can use strptime to parse your objects into POSIXlt objects which, when printed, are exactly in the format you expect:
y <- strptime(x, "%Y%m%d %H:%M:%S")
# [1] "2013-06-03 00:00:03" "2013-07-03 00:01:03" "2013-08-04 00:03:03"
To remove seconds, use trunc:
y <- trunc(y, units = "mins")
# [1] "2013-06-03 00:00:00" "2013-07-03 00:01:00" "2013-08-04 00:03:00"
Having your objects as date/time objects will open a lot of doors, but if you really mean to store the output as a character vector, then just use as.character:
y <- as.character(y)
A lubridate version:
library(lubridate)
dt <- ymd_hms(x)
dt2 <- update(dt, seconds = 0)
You can try this regex, which I added a bit:
gsub("(\\d{4})(\\d{2})(\\d{2}) (\\d{2}:\\d{2}).*", "\\1-\\2-\\3 \\4:00", subject, perl=TRUE);
