Single quotes not removed from values

[paveldanichev]

Example .env file:

key1=value1
key2="value2"
key3='value3'

Usage code:

Dotenv dotenv = Dotenv.load();
System.out.println(dotenv.get("key1"));
System.out.println(dotenv.get("key2"));
System.out.println(dotenv.get("key3"));

Output:

value1
value2
'value3'

The single quotes around value3 were not removed.

hack in case you are interested only in reading the values to system properties:

    private static void loadEnvVariables(Path path) {
        String filename = path.getFileName().toString();
        String directoryPath = path.getParent().toString();
        boolean throwIfMissing = false;
        boolean throwIfMalformed = false;
        boolean systemProperties = true;
        // Dotenv.configure() we need to use DotenvBuilder directly to be able to fix single quotes handling by use of stripSingleQuotes
        new DotenvBuilder() {
                    @Override
                    public Dotenv load() throws DotenvException {
                        final var reader = new DotenvParser(
                                new DotenvReader(directoryPath, filename),
                                throwIfMissing, throwIfMalformed);
                        final List<DotenvEntry> env = reader.parse();
                        if (systemProperties) {
                            env.forEach(it -> System.setProperty(it.getKey(), stripSingleQuotes(it.getValue())));
                        }
                        return null;
                    }
                }
                // .filename(filename)
                // .directory(directoryPath)
                // .ignoreIfMalformed()
                // .ignoreIfMissing()
                // .systemProperties()
                .load();
    }

    private static String stripSingleQuotes(String value) {
        if (value != null && value.length() >= 2 && value.startsWith("'") && value.endsWith("'")) {
            return value.substring(1, value.length() - 1);
        }
        return value;
    }

the fix for this issue can be possibly to strip single quotes in io.github.cdimascio.dotenv.internal.DotenvParser#parse

            value=stripSingleQuotes(value)
            entries.add(new DotenvEntry(key, value));
