`runtime`

Returns runtime information on the internal state of Murex

Description

runtime is a tool for querying the internal state of Murex. It’s output will be JSON dumps.

Usage

runtime flags -> <stdout>

builtins is an alias for runtime --builtins:

builtins -> <stdout>

Examples

List all the builtin data-types that support WriteArray()

» runtime --writearray

To get a list of every flag supported by runtime

runtime --help

Please also note that you can supply more than one flag. However when you do use multiple flags the top level of the JSON output will be a map of the flag names. eg

» runtime --pipes --tests
{
    "pipes": [
        "file",
        "std",
        "tcp-dial",
        "tcp-listen",
        "udp-dial",
        "udp-listen"
    ],
    "tests": {
        "state": {},
        "test": []
    }
}

» runtime --pipes
[
    "file",
    "std",
    "tcp-dial",
    "tcp-listen",
    "udp-dial",
    "udp-listen"
]

» runtime --tests
{
    "state": {},
    "test": []
}

Flags

--aliases Lists all aliases
--autocomplete Lists all autocomplete schemas - both user defined and automatically generated ones
--builtins Lists all builtin commands, compiled into Murex
--cache Returns a complete dump of everything in the local cache as well as cache DB (if compiled with persistent sqlite3 cache support)
--cache-db-enabled Returns boolean value stating if the cache DB is enabled
--cache-db-path Returns a string representation of the cache DB path (or a zero length string if cache DB support is not compiled)
--cache-namespaces Lists namespaces in cache
--clear-cache Clears all items from both the local cache and cache DB. Returns all items removed

Detail

Usage in scripts

runtime should not be used in scripts because the output of runtime may be subject to change as and when the internal mechanics of Murex change. The purpose behind runtime is not to provide an API but rather to provide a verbose “dump” of the internal running state of Murex.

If you require a stable API to script against then please use the respective command line tool. For example fid-list instead of runtime --fids. Some tools will provide a human readable output when stdout is a TTY but output a script parsable version when stdout is not a terminal.

        "Err Pipe": "err",
        "Command": "pretty",
        "Parameters": ""
    }
]

File reference

Some of the JSON dumps produced from runtime will include a map called FileRef. This is a trace of the source file that defined it. It is used by Murex to help provide meaningful errors (eg with line and character positions) however it is also useful for manually debugging user-defined properties such as which module or script defined an autocomplete schema.

Debug mode

When debug is enabled garbage collection is disabled for variables and FIDs. This means the output of runtime --variables and runtime --fids will contain more than just the currently defined variables and running functions.
