locl/cli: Unterminated $localize metadata block in ": "

[simdevmon]

I wanted to test extraction of phrases with locl/cli

ng build --prod && npx locl extract -s=dist/*.js -f=xlf2 -o=src/locale/messages.xlf

I get the following error message:

Warning: Entry point '@locl/cli' contains deep imports into '[...]/node_modules/@angular/localize/src/tools/src/diagnostics'. This is probably not a problem, but may cause the compilation of entry points to be out of order.

It would be helpful to point to the file / line, which contains an error.

Agreed, but for now I don't have this kind of info and it would require a lot of work to pass it to this part of the code. I'll add a better error message for now.

This is still an issue. I have spent hours now looking through a thousand translations to find the issue, and what is the issue isn't really clear from the error message. From the code I assume the problem is that a localize block only contains one colon at the start and none at the end of the token.
