I tried it out in that way:
// Constants used by create_publication_core
private string _filename;
private string _path;
private const string REV_HIST = "Revision_History.xml";
private const string AUTHOR_GROUP = "Author_Group.xml";
private const string ENTITY_FILE_SUFFIX = ".ent";
private const string DIRECTORY_SEPARATOR_CHAR = "/";
private const string ENTITY_FILE_LOCAL = {get {_filename =
publication_title + ENTITY_FILE_SUFFIX; return _filename;}}
private const string PROJECT_DIR = {get {_path = target_dir +
DIRECTORY_SEPARATOR_CHAR + publication_title + DIRECTORY_SEPARATOR_CHAR
+ create_language; return _path;}}
The compiler says:
core/create_publication_core.vala:51.48-51.48: error: syntax error,
expected `}'
private const string ENTITY_FILE_LOCAL = {get {_filename =
publication_title + ENTITY_FILE_SUFFIX; return _filename;}}
^
core/create_publication_core.vala:52.42-52.42: error: syntax error,
expected `}'
private const string PROJECT_DIR = {get {_path = target_dir +
DIRECTORY_SEPARATOR_CHAR + publication_title + DIRECTORY_SEPARATOR_CHAR
+ create_language; return _path;}}
Maybe i miss anything?
Greetings
Sascha
