replace string in class bash and azuredevops (ios xamarin pipeline)
I am trying to write a bash script to change a string in a class for my azure devops pipeline.But cannot make it work.
Copied the script from
https://github.com/Microsoft/appcenter-build-scripts-examples/blob/master/xamarin/app-constants/appcenter-pre-build.sh
my bash attempt:
- Added a bash task (inline script)
- Created an env variable API_URL with value ="https://production.com/api"
My Class to change
namespace Core
{
public class AppConstant
{
public const string ApiUrl = "https://production.com/api";
public const string AnotherOne="AAA";
}
}
My script
if [ ! -n "$API_URL" ]
then
echo "You need define the API_URL variable"
exit
fi
APP_CONSTANT_FILE=$(Build.SourcesDirectory)/MyProject/Core/AppConstant.cs
if [ -e "$APP_CONSTANT_FILE" ]
then
echo "Updating ApiUrl to $API_URL in AppConstant.cs"
sed -i '' 's#ApiUrl = "[a-z:./]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE
echo "File content:"
cat $APP_CONSTANT_FILE
fi
why does my variable not change? many thanks

Your script is correct and will get desired output, only remove the dual apostrophes after sed -i:
sed -i 's#ApiUrl = "[a-z:./]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE
However I would also change regexp at least to this, since . (dot) is reserved as any character in regexp:
sed -i 's#ApiUrl = "[a-z:./]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE
Or even to this (in order to take whatever characters between quotes):
sed -i 's#ApiUrl = "[^"]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE
Test:
$ cat > developer9969.txt
namespace Core
{
public class AppConstant
{
public const string ApiUrl = "https://production.com/api";
}
}
API_URL='https://kubator.com/'
APP_CONSTANT_FILE='./developer9969.txt'
sed -i 's#ApiUrl = "[^"]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE
$ cat $APP_CONSTANT_FILE
namespace Core
{
public class AppConstant
{
public const string ApiUrl = "https://kubator.com/";
}
}
Hi thanks for your time I am not familiar at all with bash as I come from windows etc.. if I wanted to replace another constant string that is not a url would I need to sed -i 's#ApiUrl = "[a-z:./]*"#ApiUrl = "'$API_URL'"#' $APP_CONSTANT_FILE becomes sed -i 's#myconst = "[a-z:]"#myconst = "'$myconst'"#' $APP_CONSTANT_FILE basically removing "./]*

This is more regular expression question. Basically means character class and * means repeat 0 or unlimited times. So that's why regular expression [a-z:./] kind matches Your url. I am saying kind because having full regexp for url is tough. At least in Your case I would repair [a-z:./]. Dot must be escaped because is alos regexp reserved as any single character. If You would like to match any non empty aplha (both upper, lower case) string I would suggest regexp: ^[A-Za-z]+$ where ^ is beginning, [A-Za-z] both upple lower alpha, + is repeat one or more times, $ is end

thanks for your help on this one i guess your are right is more about regex which is another issue i have tried as follows to replace a const but cannot do it sed -i 's#AnotherOne = "^[A-Za-z]+$"#AnotherOne = "'$ANOTHERONE'"#' $APP_CONSTANT_FILE .
– developer9969
Nov 21 '18 at 10:13
That was generic example, in this case use simply: sed -i 's#AnotherOne = "[^"]*"#AnotherOne = "'$ANOTHERONE'"#' $APP_CONSTANT_FILE
