2012-10-16GF.Command.Command: turn CommandOutput into a newtypehallgren
The output from commands is represented as ([Expr],String), where the [Expr] is used when data is piped between commands and the String is used for the final output. The String can represent the same list of trees as the [Expr] and/or contain diagnostic information. Sometimes the data that is piped between commands is not a list of trees, but e.g. a string or a list of strings. In those cases, functions like fromStrings and toStrings are used to encode the data as a [Expr]. This patch introduces a newtype for CommandOutput and collects the functions dealing with command output in one place to make it clearer what is going on. It also makes it easier to change to a more direct representation of piped data, and make pipes more "type safe", if desired.
2012-09-25Use the SIO monad in the GF shellhallgren
+ The restrictions on arbitrary IO when GF is running in restricted mode is now enforced in the types. + This hopefully also solves an intermittent problem when accessing the GF shell through the web API provided by gf -server. This was visible in the Simple Translation Tool and probably caused by some low-level bug in the GHC IO libraries.
2012-09-25GF.Command.Commands: allCommands is now a constanthallgren
The dependency on PGFEnv has been moved from the list to the exec function of the commands in the list. This means that the help command no longer needs to generate a new list of commands and that the state of the shell (type GF.Command.Interpreter.CommandEnv) no longer needs to contain the list of commands.
