I am trying to split a string only by the second to last character, for example:
Having this string xxx-xxx-xxx-xxx-xxx
I would like to get only this xxx-xxx-xxx and remove the last part after the third "-" or the second last "-", the string will always have 4 "-" and character or numbers in between.
At the moment I have something like this
{{ splitList "-" .Values.global.stackName | list ._0 ._1 ._2 | join "-" | quote }}
Does not work because I dont know how to pipe the array from the first split int the second one and join them again.
You may use the slice function to get only the first 3 elements of the splitted list:
{{ slice (splitList "-" .Values.global.stackName) 0 3 | join "-" | quote }}
Also note that if your input is guaranteed to be of fixed format (that is, 3 characters then - then 3 chars again then - then 3 chars again before -), you may use printf with the proper format string to keep only the first (at most) 11 characters:
{{ printf "%.11s" .Values.global.stackName | quote }}
If the input only contains ASCII characters (no multi-byte unicode characters), you may also slice the input string to retain only the first 11 characters (bytes):
{{ slice .Values.global.stackName 0 11 | quote }}
I suspect the piece you're missing is the initial template function, which takes a list as a parameter and returns new list without its last item.
{{ splitList "-" .Values.global.stackName | initial | join "-" | quote }}
(splitList and join aren't included in the Helm Template Function List page. But they come from a support library called Sprig which is mostly embedded into Helm as-is, and they're documented in its String Slice Functions page.)

I am creating a script converting a csv file in an another format.
To do so, i need my numbers to have a fixed format to respect column size : 00000000000000000,00 (20 characters, 2 digits after comma)
I have tried to format the number with -f and the method $value.toString("#################.##") without success
Here is an example Input :
4000000
45817,43
400000
570425,02
15864155,69
1068635,69
128586256,9
8901900,04
29393,88
126858346,88
1190011,46
2358411,95
139594,82
13929,74
11516,85
55742,78
96722,57
21408,86
717,01
54930,49
391,13
2118,64
Any hints are welcome :)
Thank you !
tl;dr:
Use 0 instead of # in the format string:
PS> $value = 128586256.9; $value.ToString('00000000000000000000.00')
00000000000128586256.90
Note:
Alternatively, you could construct the format string as an expression:
$value.ToString('0' * 20 + '.00')
The resulting string reflects the current culture with respect to the decimal mark; e.g., with fr-FR (French) in effect, , rather than . would be used; you can pass a specific [cultureinfo] object as the second argument to control what culture is used for formatting; see the docs.
As in your question, I'm assuming that $value already contains a number, which implies that you've already converted the CSV column values - which are invariably strings - to numbers.
To convert a string culture-sensitively to a number, use [double]::Parse('1,2'), for instance (this method too has an overload that allows specifying what culture to use).
Caveat: By contrast, a PowerShell cast (e.g. [double] '1.2') is by design always culture-invariant and only recognizes . as the decimal mark, irrespective of the culture currently in effect.
zerocukor287 has provided the crucial pointer:
To unconditionally represent a digit in a formatted string and default to 0 in the absence of an available digit, use 0, the zero placeholder in a .NET custom numeric format string
By contrast, #, the digit placeholder, represents only digits actually present in the input number.
To illustrate the difference:
PS> (9.1).ToString('.##')
9.1 # only 1 decimal place available, nothing is output for the missing 2nd
PS> (9.1).ToString('.00')
9.10 # only 1 decimal place available, 0 is output for the missing 2nd
Since your input uses commas as decimal point, you can split on the comma and format the whole number and the decimal part separately.
Something like this:
$csv = #'

I do things like this all the time, usually for generating computernames. That custom numeric format string reference will come in handy. If you want a literal period, you have to backslash it.

I am trying to parse all the files and verify if any of the file content has strings TESTDIR or TEST_DIR
Files contents might look something like:-
TESTDIR = foo
include $(TESTDIR)/chop.mk
...
TEST_DIR := goldimage
MAKE_TESTDIR = var_make
NEW_TEST_DIR = tesing_var
Actually I am only interested in TESTDIR ,$(TESTDIR),TEST_DIR but in my case last two lines should be ignored. I am new to perl , Can anyone help me out with re-rex.
/\bTEST_?DIR\b/
\b means a "word boundary", i.e. the place between a word character and a non-word character. "Word" here has the Perl meaning: it contains characters, numbers, and underscores.
_? means "nothing or an underscore"
Look at "characterset".
Only (space) surrounding allowed:
/^(.* )?TEST_?DIR /
^ beginning of the line
(.* )? There may be some content .* but if, its must be followed by a space
at the and says that a whitespace must be there. Otherwise use ( .*)?$ at the end.
One of a given characterset is allowed:
Should the be other characters then a space be possible you can use a character class []:
/^(.*[ \t(])?TEST_?DIR[) :=]/
(.*[ \t(])? in front of TEST_?DIR may be a (space) or a \t (tab) or ( or nothing if the line starts with itself.
afterwards there must be one of (space) or : or = or ). Followd by anything (to "anything" belongs the "=" of ":=" ...).
One of a given group is allowed:
So you need groups within () each possible group in there devided by a |:
/^(.*( |\t))?TEST_?DIR( | := | = )/
In this case, at the beginning is no change to [ \t] because each group holds only one character and \t.
At the end, there must be (single space) or := (':=' surrounded by spaces) or = ('=' surrounded by spaces), following by anything...
You can use any combination...
/^(.*[ \t(])?TEST_?DIR([) =:]| :=| =|)/

I'm getting the output of a command on the remote system and storing it in a variable. It is then used to fill in a file template which gets placed on the system.
- name: Retrieve Initiator Name
command: /usr/sbin/iscsi-iname
register: iscsiname
- name: Setup InitiatorName File
template: src=initiatorname.iscsi.template dest=/etc/iscsi/initiatorname.iscsi
The initiatorname.iscsi.template file contains:
InitiatorName={{ iscsiname.stdout_lines }}
When I run it however, I get a file with the following:
InitiatorName=[u'iqn.2005-03.org.open-iscsi:2bb08ec8f94']
What I want:
InitiatorName=iqn.2005-03.org.open-iscsi:2bb08ec8f94
What am I doing wrong?
I realize I could write this to the file with an "echo "InitiatorName=$(/usr/sbin/iscsi-iname)" > /etc/iscsi/initiatorname.iscsi" but that seems like an un-Ansible way of doing it.
Thanks in advance.
FWIW, if you really do have an array:
[u'string1', u'string2', u'string3']
And you want your template/whatever result to be NOT:
ABC=[u'string1', u'string2', u'string3']
But you prefer:
ABC=["string1", "string2", "string3"]
Then, this will do the trick:
ABC=["{{ iscsiname.stdout_lines | list | join("\", \"") }}"]
(extra backslashes due to my code being in a string originally.)
Use a filter to avoid unicode strings:
InitiatorName = {{ iscsiname.stdout_lines | to_yaml }}
Ansible Playbook Filters
To avoid the 80 symbol limit of PyYAML, just use the to_json filter instead:
InitiatorName = {{ iscsiname.stdout_lines | to_yaml }}
In my case, I'd like to create a python array from a comma seperated list. So a,b,c should become ["a", "b", "c"]. But without the 'u' prefix because I need string comparisations (without special chars) from WebSpher. Since they seems not to have the same encoding, comparisation fails. For this reason, I can't simply use var.split(',').
Since the strings contains no special chars, I just use to_json in combination with map(trim). This fixes the problem that a, b would become "a", " b".
restartApps = {{ apps.split(',') | map('trim') | list | to_json }}
Since JSON also knows arrays, I get the same result than python would generate, but without the u prefix.
I have a string variable. I need to convert all non-digit characters to spaces (" "). I have a problem with unicode characters. Unicode characters (the characters outside the basic charset) are converted to some invalid characters. See the code for example.
Is there any other way how to achieve the same result with procedure which would not choke on special unicode characters?

The substr function should not be used on the left hand side of an expression in Unicode mode, because the replacement character may not be the same number of bytes as the character(s) being replaced. Instead, use the replace function on the right hand side.
The corrupted characters you are seeing are due to this size mismatch.
How about instead of replacing non-numeric characters, you cycle though and pull out the numeric characters and rebuild Z? (Note my version here is pre CHAR. string functions.)

I have a string that looks like this:
17/07/2013 TEXTT TEXR 1 Text 1234567 456.78 987654
I need to separate this so I only end up with 2 values (in this example it's 1234567 and 456.78). The rest is unneeded.
I tried using string split with %A_Space% but as the whole middle area between values is filled with spaces, it doesn't really work.
Anyone got an idea?
src:="17/07/2013 TEXTT TEXR 1 Text "
. " 1234567 456.78 987654", pattern:="([\d\.]+)\s+([\d\.]+)"
RegexMatch(src, pattern, match)
MsgBox, 262144, % "result", % match1 "`n"match2
You should look at RegExMatch() and RegexReplace().
So, you will need to build a regex needle (I'm not an expert regexer, but this will work)
First, remove all of the string up to the end of "1 Text" since "1 Text" as you say, is constant. That will leave you with the three number values.
Something like this should find just the numbers you want:
needle:= "iO)1\s+Text"
partialstring := RegexMatch(completestring, needle, results)
lenOfFrontToRemove := results.pos() + results.len()
lastthreenumbers := substr(completestring, lenOfFrontToRemove, strlen(completestring) )
lastthreenumbers := trim(lastthreenumbers)
msgbox % lastthreenumbers
To explain the regex needle:
- the i means case insensitive
- the O stands for options - it lets us use results.pos and results.len
- the \s means to look for whitespace; the + means to look for more than one if present.
Now you have just the last three numbers.
1234567 456.78 987654
But you get the idea, right? You should able to parse it from here.
Some hints: in a regex needle, use \d to find any digit, and the + to make it look for more than one in a row. If you want to find the period, use \.
