dbstatus — Return RunMat debugger breakpoint status.
dbstatus returns RunMat's breakpoint registry state.
Syntax
dbstatus
b = dbstatus(file, '-completenames')Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
name | StringScalar | No | — | Function, script, file, command, or option text. |
Returns
| Name | Type | Description |
|---|---|---|
b | Any | Breakpoint entries as a 1-by-N cell row; currently empty until execution breakpoints are implemented. |
Returned values from dbstatus depend on how many outputs the caller requests.
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:TooManyInputs | A debugger compatibility helper receives more inputs than it supports. | debugger helper: too many input arguments |
RunMat:InvalidInput | An input is not a supported text, scalar, or option value. | debugger helper: invalid input |
RunMat:NoCurrentFile | `mlock`, `munlock`, or `mislocked` is called without a current function or script. | debugger helper: no current function or script is available |
RunMat:FileNotFound | `dbtype` cannot resolve a MATLAB source file. | dbtype: file not found |
RunMat:FileReadFailed | `dbtype` cannot read the resolved source file. | dbtype: failed to read file |
How dbstatus works
dbstatusaccepts MATLAB-style file and'-completenames'text arguments.- RunMat does not yet implement execution breakpoints or
dbstop, so the current status is an empty 0-by-0 cell list. - The empty-list representation uses a cell because RunMat does not yet have first-class MATLAB struct arrays.
Does RunMat run dbstatus on the GPU?
dbstatus is host-side debugger state and has no GPU/provider behavior.
Example
Query breakpoint state
b = dbstatus;Using dbstatus with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how dbstatus changes the result.
Run a small dbstatus example, explain the result, then change one input and compare the output.
FAQ
Does dbstatus list MATLAB breakpoints?⌄
Not yet. The interactive breakpoint engine is a broader runtime feature; this compatibility helper returns the currently empty registry.
