convex.run
Convex Lisp Runner.
Executes each form as a transaction, moving from transaction to transaction.
A transaction can return a request to perform operations beyond the scope of the CVM, such as file IO or advancing time. Those requests turn Convex Lisp, a somewhat limited and fully deterministic language, into a scripting facility.
Requests are vectors following expected conventions and implementations can be found in the [[convex.run.sreq]] namespace.
A series of CVX libraries is embedded, building on those requests and the way the runner generally operates, providing features such as reading CVX files, unit testing, a REPL, or time-travel. All features are self documented in the grand tradition of Lisp languages.
Functions throughout these namespaces often refer to env. It is an environment map passed around containing
everything that is need by an instance: current CVM context, opened streams, current error if any, etc.
In case of error, convex.run.exec/fail must be used so that the error is reported to the CVX executing environment.
List of transactions pending for execution is accessible in the CVX execution environment under $.trx/*list*. This list
can be modified by the user, allowing for powerful metaprogramming. Besides above-mentioned requests, this feature is used
to implement another series of useful utilities such as exception catching.

-mainclj
(-main & trx+)Reads and executes transactions.
If no transaction is provided, starts the REPL.
Reads and executes transactions. If no transaction is provided, starts the REPL.
initclj
(init env)Used by eval to initiate env.
Notably, prepares:
- STDIO streams
- Initial context
- Function under
:convex.run/fatal, akin toconvex.run.exec/fail, called only in case of a fatal error that cannot be reported to the CVX environment (seldom)
Used by [[eval]] to initiate `env`. Notably, prepares: - STDIO streams - Initial context - Function under `:convex.run/fatal`, akin to [[convex.run.exec/fail]], called only in case of a fatal error that cannot be reported to the CVX environment (seldom)
