Saving breakpoints in a script

Suppose I put breakpoints in a script. I want to save these breakpoints so that I can reuuse them in a next session.

I have seen

https://stackoverflow.com/questions/12657219/how-to-restore-breakpoints-in-matlab-after-clear-all

Then what would be the specific steps to save breakpoints? Shall I just put

%# store breakpoints
tmp = dbstatus;
save('tmp.mat','tmp')

%# clear all
close all
clear classes %# clears even more than clear all
clc

%# reload breakpoints
load('tmp.mat')
dbstop(tmp)

%# clean up
clear tmp
delete('tmp.mat')

at the beginning of the script?

No, do not insert this into the script. Keep the information about debugging and the actual code separated.

When you want to store the breakpoints, call:

status = dbstatus;
save('DBStatus.mat', 'status')

and to restore them, run:

Data = load('DBStatus.mat');
dbstatus(Data.status);

Maybe you want to store this in a function.

It means I run this code on the command line? What will be the steps?

[Jan]

It depends, on what you want to do exactly. Let me guess this important detail...

function dbstore(Command)
File = fullfile(prefdir, 'DBStatus.mat');
if narging == 0
  status = dbstatus;
  save(File, 'status');
else
  Data = load(File);
  dbstop(Data.status);  % [EDITED], Typo fixed
end
end

Store this file as "dbstore.m" in one of your user-defined folders. Now call

dbstore

to store the breakpoints and

dbstore restore

(or any other argument) to restore the last saved breakpoints, either after a clear all, dbclear or restart of Matlab.

The loading routine should call

dbstop(Data.status)

to set breakpoints, not "dbstatus".

[Omer Ben-Yshai]

right.

This works, except for the last command I used dbstop(DataStat.status);
