How to use quotation mark in EL Strings? - jsf

I get the Error: EL Expression Unbalanced while trying to add quotation mark in EL String. How can I do that?
#{chainModel.selectedChain.equalsIgnoreCase("")
? 'Kettenbearbeitung' :
'Verkettung'
.concat('"')
.concat(chainModel.selectedChain)
.concat('"')}


Try to use \" ASCII HTML Names to avoid JSF Syntax validations when you need to concat JAVA values with complex strings. Or use \" for double quotes or \' for simple quotes and it will be simplified when you need for a simple string.
In your case I propouse the following:
? 'Kettenbearbeitung' :
'Verkettung'
.concat('\"')
.concat(chainModel.selectedChain)
.concat('\"')

Replacing string with variable with Groovy and SED command

I am trying to replace an entire description string contained in an XML file. I would like to replace that string with a variable. I am using a SED command within a Groovy script.
I have the following code. I am expecting the string "foo" to replace the description text but it doesn't.
Instead the following line causes the XML to change to:
Description="sDescription"
What am I doing wrong?
def sDescription = "foo"
def sedCommand = 'sed -i \'s/Description="[^"]*"/Description="'$sDescription'"/g\' package.appxmanifest' as String

In Groovy variable/expression substitution inside of strings (interpolation) only works with certain types of string literal syntax. Single quote syntax ('content') is not one of them. However, if you replace the outer single quotes with double quotes ("content") then you should get the interpolation effect you are looking for:
def sDescription = "foo"
def sedCommand = "sed -i 's/Description=\"[^\"]*\"/Description=\"$sDescription\"/g\' package.appxmanifest" as String
This should give you the string that contains the command you wish to run. Please note how I changed the special character escaping (\) within the string to reflect the change in string delimiters.
Aside: As noted by #tim_yates, Why would you want to invoke a separate ad hoc process to do this substitution when Groovy contains excellent XML manipulation facilities built into the language?

How to replace string in Groovy

I have some string like
C:\dev\deploy_test.log
I want by means of Groovy to convert string to
C:/dev/deploy_test.log
I try to perform it with command
Change_1 = Log_file_1.replaceAll('\','/');
It doesn't convert this string

You need to escape the backslash \:
println yourString.replace("\\", "/")

You could also use Groovy's slashy string, which helps reduce the clutter of Java's escape character \ requirements. In this case, you would use:
Change_1 = Log_file_1.replaceAll(/\/,'/');
Slashy strings also support interpolation, and can be multi-line. They're a great tool to add to your expertise.

Cannot assign string with single quote in golang

I am learning go and when playing with string I noticed that if a string is in single quotes then golang is giving me an error but double quotes are working fine.
func main() {
var a string
a = 'hello' //will give error
a = "hello" //will not give error
}
This is the error I get on my system:
illegal rune literal
While when I try to do the same on playground I am getting this error:
prog.go:9: missing '
prog.go:9: syntax error: unexpected name, expecting semicolon or newline or }
prog.go:9: newline in string
prog.go:9: empty character literal or unescaped ' in character literal
prog.go:9: missing '
I am not able to understand the exact reason behind this as in for example Python, Perl one can declare a string with both single and double quote.

In Go, '⌘' represents a single character (called a Rune), whereas "⌘" represents a string containing the character ⌘.
This is true in many programming languages where the difference between strings and characters is notable, such as C++.
Check out the "Code points, characters, and runes" section in the Go Blog on Strings

Another option, if you are wanting to embed double quotes:
package main
func main() {
s := `west "north" east`
println(s)
}
https://golang.org/ref/spec#raw_string_lit

Go is a statically typed language. Also Go is not a scripting language. Though we see Go is running like a scripting language, it is compiling the source we write and then execute the main function. So, we should treat Go as C, Java, C++ where single quote ' is used to declare characters (rune, char) unlike scripting languages like Python or JavaScript.
I think as this is a new language, and current trend is lying with scripting languages, this confusion has been occurred.

I tried with double quotes as well. What shall /i do?

Strings are enclosed in double-quotes like "this". If you want a string to actually contain a double-quote use it twice like:
"here is a ""double-quote"" - ok?"
You can also use single-quotes like 'this' and 'here is a ' 'single-quote' ' - ok?'
You can mix quote types to make for easier working and to avoid having to double-up your quotes to get what you want. For example if you want to use a lot of double-quotes in your strings then you should use single-quotes for declaring them:
'This "sentence" contains "lots" of "double-quotes" does it not?'
is much simpler than:
"This ""sentence"" contains ""lots"" of ""double-quotes"" does it not?"
Just use ' instead of ".
Like this:
$myformula = '=IF(OR(ISNUMBER(search(" "&{"quality","st","rainbow","carryout","auto","surgery","public","fertiliser","Fertilisers","ifertilisersl","rendezvous","remember","that","precast","barefoot","mail","scaffolding","safe","access","salvation","army","funeral","directors","director","seahorse","simply","affordable","stich","time","dressmaking","alterations","hospital","by","jewellers","post","sweet","sensation","trophies","engraving","protection","produce","public","relations","made","fun","auctions","auction","kiltmakers","kiltmaker","linen","chippy","timber","tidy","tangles","past","dealer","trading","crafts","craft","naval","activities","US","Uncle","Diner","Removals","Volunteer","Zoo","Wavelength","Wavelengths","Friends","hairdressing","theatreclub","daynursery","MUSLC","superstore","colleges","AALCO","AARDVARK","ABACUS","ABB","ABBOTSWELL","ABBOTTPUBLIC","ABC","ABCON","ABDN","ABERCARE","ABERDEE","ABERDEEN","ABERDEENSHIRE","ABERFLORA","ABERGELDIE","ABERGLEN","ABERLOUR","ABERMED","ABERNE","ABERPEST","ABERSOL","ABERT","ABSCOT","ABSOFT","ABSPEK","ABSURE","ABTEX","ABTRUST","ACADEMY","ACCESS","ACCESSORIES","ACCOMMODATION","ACCORD","ACCOUNTANCY","ACCURAY","ACE","ACTION","ADAPT","ADEPT","ADMIN","ADMIRAL","ADS","ADULT","ADVANCE","ADVANCED","ADVANT","ADVANTAGE","ADVICE","AEA","AFFAIR","AFOS","AGA","AGE","AGENCY","AGIP","AGRI","AGRICULTURAL","AGRICULTURE","AHT","AI","AIDS","AIR","AIRBORNE","AIRFAIR","AIRLINES","AIRNAUTIC","AIRPAC","AIRPORT","AIRWAYS","AIRYHALL","AIRYLEA","AKRON","ALAD","ALASDAIR","ALB","ALBATECH","ALFA","ALL","ALLIANCE","ALLIED","ALLOMAX","ALPINE","ALSTEV","ALTERNATIVES","ALTRA","ALWAYS","ALZHEIMER","AM","AMALGAMATED","AMAT","AMATOLA","AMBER","AMEC","AMERICAN","AMETEK","AMIN","AMITEC","AMOCO","AMTECH","AMTRAK","AMUSEMENT","AND","ANDERGAUGE","ANIXTER","ANKA","ANTIQUES","ANTRIM","AOC","AP","APARDION","APEX","APOLLO","APOSTOLIC","APPEALS","APPLIED","APPOLLO","AQUA","AQUARISTS","AQUATEC","AQUATIC","AQUIDATA","ARCHITECTURAL","ARCO","ARGONAUT","ARGOSY","ARISTACUT","ARJO","ARJON","ARKAIG","ARTISTES","ARTISTS","ARTWORKS","ARUP","AS","ASA","ASCOT","ASDASUPERSTORES","ASHVALE","ASPECT","ASSEMBLIES","ASSESSORS","ASSOCIATED","ASSOCIATES","ASSOCIATION","ASSURANCE","ASTER","ASTRA","ATEL","ATHENA","ATHENAEUM","ATHOLL","ATLANTIC","AUCHMILL","AUCHTERLESS","AUGHTON","AUGUST","AUP","AUQUHARNEY","AURORA","AUTO","AUTOFIX","AUTOGLASS","AUTOMAGIC","AUTOQUICK","AUTOSAVE","AUTOSPRAY","AUTOTRUCK","AVCO","AVENUE","AWAKENING","AWAY","AXIOM","AZTEC","BAADER","BALNAGASK","BANKHEAD","BAR","BARICO","BARRIER","BARTERING","BASELINE","BATCHBRIGHT","BATH","BATHROOM","BAVARIA","BAYLISS","BAYLOR","BEARING","BEATTIES","BEAUTY","BEAVERBROOKS","BEECHWOOD","BEEFEATER","BEELINE","BEFRIEND","BENBOW","BESTWAY","BEWS","BIKES","BLIND","BLINDCRAFT","BLINDS","BLOOD","BLOOMING","BLOSSOMS","BLOW","BLUEBELLS","BMT","BNA","BOARD","BOARS","BOAT","BODY","BOHEMIA","BOILERMAKERS","BON","BONADDIO","BONAVENTURE","BONIVIEW","BONNYMUIR","BOOKBINDING","BOOTS","BOROWSKI","BORSALINO","BOSANQUET","BOSCH","BOTTLED","BOULEVARD","BOURTREE","BOWEN","BOWLING","BOWTECH","BOX","BP","BPCC","BRA","BRACKENRIDGE","BRAEHEAD","BRAESIDE","BRAKE","BRIEF","BRITANNIA","BRITANNIC","BROAD","BROADCAST","BROADSTRAIK","BROS","BROTHERHOOD","BRUNSWICK","BUCKSBURN","BUDGET","BUILDING","BULAWEYO","BUREAU","BURNTHILLS","BUS","BUSINESS","CABER","CABINS","CABLE","CABS","CAFE","CAIRD","CAIRNCRY","CAIRNGORM","CAKE","CALEDON","CALEDONIA","CALEDONIAN","CALLANDERS","CALOR","CALTEC","CALVARYTABERNACLEUNITED","CAMARGUE","CAMEO","CAMPAIGN","CAMPBELLS","CAMPHILL","CAMWATER","CAN","CANALE","CANCER","CANDO","CANSCO","CAPE","CARADON","CARD","CAREERS","CARGO","CARPET","CARPETS"}&" "," "&b1&" "))),"YES","NO")'

You have a lot of quotes in there. Try rewriting it adding just one string at a time...once you get it working, then you can start adding more than one string at a time.

How to write a hardcoded string value inside EL expression #{ } in JSF?

I am trying to do the following:
rendered="#{billBean.company.equals("something")}"
But the problem is I cannot write "something" inside #{}. It causes the below XML parsing error:
Element type "h:commandLink" must be followed by either attribute specifications, ">" or "/>".
How can I achieve this?

Use single quote (') to refer to a plain String inside EL:
rendered="#{billBean.company.equals('something')}"
