mcmd pseudo file

The special remote file 'mcmd' takes the form of an I/O driver where the file name is interpreted as a query and the retrieved data is the answer to this request. Except for the dsostream command that can also be open in write mode, 'mcmd' only supports read access. A file name for this driver has the following form:

mcmd:cmd[-opts][@mod[.submod]] cmdargs

cmd:

the operation to execute ( e.g. 'eval', 'profres'...).

opts:

options to change the format of the result. By default all data are sent using the Mosel binary format 'bin:'. Adding option 't' switches to text format (still compatible with initialisations blocks) and 'j' will cause results to be sent as a JSON object (not compatible with initialisations blocks). If option 'z' is used the resulting file is compressed with gzip. A given command may also support additional options (see 'lslib'). Except for the 'eval' command, the result set publishes always the same records that are either scalars of basic types or lists of basic types. When a collection of values is returned a specific label indicating the dimension of the list precedes the list.

mod:

master model on which the operation will be performed.

submod:

submodel. Only some operations can be applied to a submodel. Note that submodel '0' is the master model itself (the first submodel has ID '1').

Supported commands:

covres (model)

Retrieve profiling results for test coverage. This command can only be called after the model has been run in profiling mode (see Section Profiler interface).

dbgbrkp [ lndx [ cond|* ] ] (model or submodel)

Breakpoint management. The model must be suspended. Without any parameters this command returns the current list of breakpoints; the first parameter is interpreted as a line index and the second parameter is a logical expression ( i.e. the breakpoint condition). With only one parameter, the breakpoint on the corresponding line index is removed (no operation is performed if there was no breakpoint). Use '*' to remove all breakpoints. With two parameters the corresponding breakpoint is created (or modified). To set an unconditional breakpoint use '*' as the condition. Note that breakpoints are attached to a model: even if several models running concurrently are resulting from the same source file, setting a breakpoint for one model (instance) will have no effect on the others.

Rlndx: range
lndx:  array(Rlndx) of integer
cond:  array(Rlndx) of string

dbgflndx [ fctname|* ] (model or submodel)

Line indices corresponding to a function name. This command returns the line indices corresponding to the beginning of the requested function (several values are returned when the routine is overloaded). Without any arguments or with argument '*', the command returns all functions of the model. If option 'N' is used, the arrays are sorted according to the function names. With option 'L' arrays are sorted following the line indices order.

Rsign: range
sign:  array(Rsign) of string
lndx:  array(Rsign) of integer
name:  array(Rsign) of string

dbglndx (model or submodel)

Retrieve the mapping of the line indices of a model/submodel. The model must be either suspended or not running. The debugger interface works on line indices: each line index corresponds to a file name and a line number in this file.

Rfiles: range
files:  array(Rlines:range) of integer
Rlines: range
lines:  array(Rfiles:range) of string

dbgstat (model or submodel)

Current execution status of a model. The model must be suspended. If no submodel is specified, statuses of all submodels are returned in addition to the master model (to get the status of the master model only use submodel '0').

Rid:  range
id:   array(Rid) of integer
stat: array(Rid) of integer
stlev:array(Rid) of integer
lndx: array(Rid) of integer

dbgstlev [ stlev|* [ maxlev ] ] (model or submodel)

Stack management. The model must be suspended. Without any arguments or with argument '*', the command returns a stack dump ( i.e. a list of line indices). If the argument is ≥0, it becomes the current stack level. The optional argument 'maxlev' defines the maximum number of levels to return (default:10). The stack level defines the context in which expression evaluations are performed in the 'eval' command.

Rid: range
id:  array(Rid) of integer
stat:array(Rid) of integer
stlev:array(Rid) of integer
lndx:array(Rid) of integer

dsostream dsoname [specific parameters] (model or submodel)

This command opens a stream to the specified module (this command supports both read and write mode). The module must implement the SRV_DSOSTRE service. The behaviour of the stream and the expected parameters depend on the implementation.

eval label:expression [ range ] (model or submodel)

Evaluate an expression in the context of the provided model/submodel. Execution of the model must be completed or suspended. If option 'i' is used, array indices are reported as order numbers instead of values. With option 'n' array values are replaced by empty strings. The label " label" is used to identify the expresion in the result file: if it is '.' no label is generated (the data result is directly sent to the result file), if it is omitted then the expression itself is used as the label, otherwise the provided string is the label. Several expressions may be evaluated in a single request (in this case they must all be labelled).
It is possible to grab only a part of a collection (array, set or list) by specifying range information. Ranges definitions take one of these two forms:

• [ maxelt ]: get at most 'maxelt' elements
• [ skip maxelt ]: get at most 'maxelt' entries after skipping 'skip' elements

Several range definitions may be specified (separated by blanks): they are used when exploring complex structures ( e.g. a list of list). The structure and type of the result set depends on the expression.

info (instance, model or submodel)

This command reports all symbols defined by Mosel (if used without specifying any argument), a module (the argument is the module name) or a model (the argument is a model or submodel ID). In the case of a module, the command loads the module if it is not yet in memory. For a model (or package), it must have been loaded prior to this command since it is referenced by its ID and be either not running or suspended. Information returned by the 'info' command:

typs:    array(Rtyps) of string
typscod: array(Rtyps) of integer

profres [ path ] (model)

Retrieve profiling results. This command can only be called after the model has been run in profiling mode (see Section Profiler interface). The path argument indicates which execution is requested: several "executions" may be available when the model starts other models with 'mmjobs' (the returned data set includes the number of additional executions available via the nbsub field). For instance the path 1.3 corresponds to the third "execution" started by the first "execution".
