Grakn Console 2.0.0-alpha-9

New Features

Bugs Fixed

• Actually save transaction option parameters to fields
  Fix null pointer in transaction options that occurs because the option builder is not saved.

Code Refactors

Other Improvements

• Update client-java
  We updated client-java to the latest server protocol.

Grakn Console 2.0.0-alpha-8

New Features

• Introduce transaction options
  Allow console users to set any transaction options they like, by introducing Options that can be provided as --flag when opening a transaction. This will simplify debugging (especially for reasoner), and allow us to experiment with parallel/not parallel, along with all other available options.

• Allow specifying commands from command line without using script
  Allow having a list of commands specified in the command line, without using script file.

• Use self-hosted Bazel cache
  Speed up CI by using self-hosted remote Bazel cache

Bugs Fixed

Code Refactors

Other Improvements

• Bump dependencies for alpha-7 release
  Bump VERSION, dependencies and artifact to prepare for release of console alpha-7

Grakn Console 2.0.0-alpha-7

New Features

• Add option to read from any replica in Cluster
  We added the --any-replica flag when opening a transaction in Cluster. When --any-replica is set, the transaction may read from any database replica, including secondary replicas.

Bugs Fixed

Code Refactors

Other Improvements

• When no databases are present, say as much on database list
  Previously, running database list with no databases present on the server gave no output and was difficult to distinguish from the console hanging or the server otherwise failing to respond. We added a more explicit response when no database is present on the server to make it clearer when this case has occurred.

• Reenable remote build caching
  Speed up builds by utilizing remote caching provided by BuildBuddy.

Other Improvements

• Fix console warnings caused by out of date dependency
  Fix WARNING: An illegal reflective access operation has occurred warning caused by an out of date version of protobuf.

• Add Grakn Cluster support
  We have added Grakn Cluster support. A user can connect to a cluster of Grakn Cluster instances using the --cluster flag:

  ./grakn console --cluster 172.0.01:1729
  

• Show the number of answers printed and the duration of a query
  We added statistic information to the UI about how many answers were printed and how long did the query take.

• Improve type safety by restricting type casting
  We've improved the type safety of the code by restricting type casting. To be consistent with a single pattern of performing dynamic casting, we convert all usage of instanceof to isX() and asX().

• Allow pasting multiline input
  Allow user to paste multiline input to console and edit as one unit.

• Fix console exitting when trying to open transaction to a database that doesn't exist
  We have fixed an issue that caused console to exit when trying to open transaction to a database that doesn't exist.

New Grakn Console: powered by PicoCLI

We've also rebuilt the Grakn Console using PicoCLI, which provides much more expressive CLI utilities, allowing us to build a richer and user-friendly console environment for Grakn. This change sets up the ecosystem for us to continue extending our Grakn Console with new features in a cohesive and backwards-compatible way.

The new Grakn Console provides two levels of interaction: database-level and transaction-level interfaces. The database-level interface is the first level of interaction, i.e. first-level REPL. From one of the database-level commands, you can open a transaction to the database. This will open a transaction-level interface, i.e. second-level REPL.

Please refer to full release notes of Grakn 2.0.0-alpha to see the changes in Grakn 2.0.0.

Running Grakn Console in the terminal

Go to the directory when you have your grakn-core-all or grakn-core-console distribution unarchived, and run ./grakn console

cd <your_grakn_console_dir>/
./grakn console

Command line arguments

You can provide several command arguments when running console in the terminal.

• --server=<address> : Server address to which the console will connect to.
• -V, --version : Print version information and exit.
• -h, --help : Show help message.

Console commands

Grakn Console provides two levels of interaction: database-level commands and transaction-level commands. The database-level command is the first level of interaction, i.e. first-level REPL. From one of the database-level commands, you can open a transaction to the database. This will open a transaction-level interface, i.e. second-level REPL.

Database-level commands

• database create <db> : Create a database with name <db> on the server. For example:

  > database create my-grakn-database
  Database 'my-grakn-database' created
  

• database list : List the databases on the server. For example:

  > database list
  my-grakn-database
  

• database delete <db> : Delete a database with name <db> on the server. For example:

  > database delete my-grakn-database
  Database 'my-grakn-database' deleted
  

• transaction <db> schema|data read|write : Start a transaction to database <db> with session type schema or data, and transaction type write or read. For example:

  > transaction my-grakn-database schema write
  my-grakn-database::schema::write>
  

  This will then take you to the transaction-level interface, i.e. the second-level REPL.
• help : Print help menu
• clear : Clear console screen
• exit : Exit console

Transaction-level commands

• <query> : Once you're in the transaction REPL, the terminal immediately accepts a multi-line Graql query, and will execute it when you hit enter twice. For example:

  my-grakn-database::schema::write> define
                                    name sub attribute, value string;
                                    person sub entity, owns name;
  
  Concepts have been defined
  

• source <file> : Run Graql queries in a file, which you can refer to using relative or absolute path. For example:

  my-grakn-database::schema::write> source ./schema.gql
  Concepts have been defined
  

• commit : Commit the transaction changes and close transaction. For example:

  my-grakn-database::schema::write> commit
  Transaction changes committed
  

• rollback : Will remove any uncommitted changes you've made in the transaction, while leaving transaction open. For example:

  my-grakn-database::schema::write> rollback
  Rolled back to the beginning of the transaction
  

• close : Close the transaction without committing changes, and takes you back to the database-level interface, i.e. first-level REPL. For example:

  my-grakn-database::schema::write> close
  Transaction closed without committing changes
  

• help : Print this help menu
• clear : Clear console screen
• exit : Exit console
