The complete MOLTO TT prototype editor code is downloadable as an eclipse (Helios) project archive http://tfs.cc/molto/molto-tt-0.9-linux-eclipse-20120529.zip. The TT editor's database back-end Haskell source code is packaged as http://tfs.cc/molto/molto-tt-server-0.9-linux-20120529.zip.
Install apache and fastcgi with apt-get:
sudo apt-get install apache2 libapache2-mod-fastcgi
Here is a sample Apache2 virtual host below to handle the MOLTO TT back end services from port 8888 (the default). The back end server is supposed to be in the same domain as the editor to avoid cross-domain scripting violations. Copy the text below to /etc/apache2/sites-available/default
<VirtualHost *:8888>

<Directory />

# Make action pgf-service handle pgf files
Action pgf-service /fcgi-bin/pgf-service
AddHandler pgf-service .pgf
AddCharset UTF-8 .pgf
</VirtualHost>
After you have copied the above to /etc/apache2/sites-available/default, activate the changes:
sudo a2enmod fastcgi sudo a2enmod actions
Finally, restart apache by typing sudo service apache2 restart.
sudo chown -R root:www-data /var/www/ (the name of the group might vary, you can see yours by seeing which group has /var/www; do grep "/var/www" /etc/passwd).Get the latest sources for GF from darcs repository. The instructions are here: http://www.grammaticalframework.org/download/index.html
Assuming you have the source files, go to src/server and type sudo cabal install -f content --global. It is important to use the option --global, because by default they are installed in the home directory, and that doesn't go well with Apache. The binaries will be installed in /usr/local/bin. Because of Apache, you need to set their owner group to the apache group (depending on machine, e.g. www-data or apache).
The next step is to link the binaries to /var/www/fcgi-bin.
/var/www$ sudo ln -s /usr/local/bin/content-service fcgi-bin/ /var/www$ sudo ln -s /usr/local/bin/pgf-service fcgi-bin/
gf-server-1.0 depends on fastcgi-3001.0.2.3 which failed to install.
sudo apt-get install libfcgi-dev), then try again to install PGF service and content service: sudo cabal install -f content --globalThis applies only if you want to use the editor from Eclipse. Otherwise you don't need any of this.
To test the TT editor under eclipse using GWT devMode, we found it necessary to recompile content-service to add the gwt code server port parameter to page URLs. To do so activate the following lines in ContentService.hs . We have been using eclipse 3.6 JEE with Google Web Toolkit version 2.3.1.
-- devModeScriptName = (liftM2 (++)) (getVarWithDefault "SCRIPT_NAME" "") (return "?gwt.codesvr=127.0.0.1:9997") -- path <- devModeScriptName
A corresponding change is neeeded in the client code. Activate the following line in TT-0.9/src/org/grammaticalframework/ui/gwt/client/SettingsPanel.java
// String defaultUrl = "/fcgi-bin/content-service?gwt.codesvr=127.0.0.1:9997";

First you need to install HSQL. It's in hackage, so it can be installed by typing sudo cabal install hsql --global.
The public version of the Haskell MySQL package hsql-mysql-1.8.1 used by the TT content service appears to have a bug that prevents multiple successive mysql procedure calls. A debugged version of the package can be found at http://tfs.cc/molto/hsql-mysql-1.8.1-molto.zip.
Install the debugged version:
hsql-mysql-1.8.1-molto.ziphsql-mysql.cabalsudo cabal install --globalsudo cabal install hsql-1.8.1 --global or downloading the version from hackage. In addition to the above, you need a mysql server. You can install one by typing sudo apt-get install mysql-server.
Content-service uses a mysql database to store users, grammars and documents.
To create the database connection you need to do the following steps:
host db user pwd in format known to haskell readFile.content-service fpath
Now create the database:
$ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. ... mysql> CREATE DATABASE moltodb; CREATE USER moltouser IDENTIFIED BY 'moltopass'; GRANT ALL on moltodb.* to moltouser; Query OK, 1 row affected (0.02 sec) mysql> Query OK, 0 rows affected (0.00 sec) mysql> Query OK, 0 rows affected (0.00 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | moltodb | +--------------------+ 2 rows in set (0.00 sec) mysql> quit Bye
Next, create the database files.
/usr/local/bin$ ./content-service fpath
And then log in to mysql with the user moltouser.
mysql -u moltouser -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. mysql> use moltodb; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +-------------------+ | Tables_in_moltodb | +-------------------+ | Documents | | GrammarUsers | | Grammars | | Users | +-------------------+ 4 rows in set (0.00 sec)
If so the tables got created ok.
There is nothing yet in the tables. After you first sign in with your google account, then your user account will be in the table Users. You can query any of the tables by writing select * from <table>.
To install the tabular equivalents editor source, do this:
https://svn.it.helsinki.fi/repos/molto/trunk/molto_term_editor/ and put it in any place where the apache server can reach, i.e. /var/www/.
http://extjs.cachefly.net/ext-4.0.2a-gpl.zip, and uncompress it as extjs-4.0.3 under the directory molto_term_editor/.
http://localhost/molto_term_editor/editor_sparql.html, if you put the source code under /var/www/.
