<p>I heard a lot of people complaining that code editors are bad 'cause it's hard
|
||
|
to attach a debugger. I'd claim that this vision is wrong.</p>
|
||
|
<span id="continue-reading"></span>
|
||
|
<p>But let's take a thing out of the way beforehand: I'm not saying debuggers are
|
||
|
<em>bad</em> you should never use them. Debuggers have their use, but every time I
|
||
|
had to use one, it was because there was something missing.</p>
|
||
|
<p>Most recently, using a framework in Java, I had problems with my code. I'd
|
||
|
expect it <a href="/books/things-i-learnt/crash-it">to crash</a> 'cause I didn't handle
|
||
|
things. What actually happened is that the framework silently hid the error
|
||
|
and restarted the processing. To find out what was happening, I had to attach
|
||
|
a debugger and see what was wrong with the data; otherwise, I'd have no idea
|
||
|
about what's wrong.</p>
|
||
|
<p>Was a debugger necessary there? I don't think so. If the framework actually
|
||
|
displayed the error (crashed, put a wall of text on the logs, whatever), I
|
||
|
wouldn't need to use a debugger. But, because something was missing, I did,
|
||
|
in fact, was <em>forced</em> to use a debugger.</p>
|
||
|
<p>Besides this, in the long run, you'd end up with problems in locations that
|
||
|
you can't attach a debugger -- for example, your production environment. You
|
||
|
<em>could</em> but you <em>shouldn't</em> do this. On the other hand, if you <a href="/books/things-i-learnt/log-events">log
|
||
|
events</a>, then you can see what was going
|
||
|
on, without a debugger.</p>
|
||
|
<p>Again, I'm not taking the merits of debuggers, but in the long run, they are
|
||
|
mostly useless and actually point missing surrounding support to actually
|
||
|
understand what's going on.</p>
