I haven't looked at my signature in a year! And my memory just isn't that good!

How the hell did this happen?
I have about 4 new C# source files the documentation for which could fill a book.
It's not about the API, but how you use it that creates all the churn.
Parser generators. Meh.
Documenting this is going to take so much more work than building it.
I need a technical writing staff, suddenly.

I find that copious comments are preferable to formal documentation. Formal docs get lost/forgotten about, and aren't nearly as well maintained as the code base itself. I try to limit formal docs to general "how-it-should-work" info, and this usually is restricted to lightly annotated Visio flow diagrams.

normally i agree with you and i try to stick by that.
i'm stuck here though as comments won't help people factor LL(1) grammars or understand the specific flavor of EBNF and regex syntaxes supported.
this is user doc, not dev doc.
well, in this case the user and the dev are the same, but the dev won't be touching this code - see also, parser generator.

That's OK if your readers are devs, but if it's end users, they'll misunderstand everything, screw everything up, then demand that you make the system work the way they thought you said it worked.

For what it's worth, I'd rather see a complete working program using the API than a 'comprehensive' document.
Most API documentation is awful. It's outlined by class or interface. Subheadings are methods or types. There's a one sentence description, usually of the form "Implements the frammenspanner factory." Methods are the same. They never tell you when you may want to invoke a method or why, what the prerequisites are, and so on. The whole thing is f***ing useless.

"Technically correct, but practically useless"
I feel you.
I'm in agreement, but here it's not enough.
I have formats to document, like the EBNF and regex flavors I use (though I tried to keep to well known varieties), and concepts like why one would for example, want to call cfg.ToLL1Parser(...) as opposed to cfg.ToLalrParser(...) - like what the hell is the difference? there's 3 chapters.
LOL
But yeah, I think i'm going to rely heavily on sample code and apps to convey what i need to but i still need to put out enough docs to get people going, which pushes my article submission here out. It's already a week or two out at least, i think.

The trick I've found with writing such documentation is to keep it pared down to what the user needs to know (stuff specific to what you're doing), and when to refer them elsewhere for background or detailed information.

Start from scratch or not?[^]
Around two years ago I posted this and the approach I took was keep using the existing software , maintain/remove bug as need arises and in paralalel looking at feasibilty for designing from scratch with maximum reusability.
After due diligence and 1 year later, I presented my findings. Manager and above decided the cost is too much and don't see ROI .
Fast Forward 1 year and new manager comes in. He going through the shelved projects mentions for the Redesign.
Catch is that he is adding too many features and the old software requirement is just now a small part of his new vision how this software should like. Question is will this manager stay long enough to see this through?
So instead of redesigning a new blender , end up designing a new kitchen where new blender will be in the corner.
cheers,
Super

Sounds like job security and you get to design it the way you want. That sounds good to me, unless of course it's an addition to an already full plate.

Looks like you get that new blender you've always wanted, so... silver linings.

I was expecting something more on the order of "let us know when you need to stop and reload; we can talk then."

Start with your proper code update - if the manager's around long enough you can build the rest around it (keep in back mind at design time, of course).
This way you can do the right thing, and if necessary, what they want, too.
I all-too-often come in contact (i.e., conflict) with manager-users specifying what they want an application to do with the ease of drawing boxes on paper and, of course, not a clue what each of their boxes of delight may entail in the background code.

Sounds excellent, but you probably would like to see *something* go into production. Draw up a plan for the Kitchen Project. Anticipate changes. Break the plan up into phases. Phase 1- Awesome Blender. If management and/or priorities change in time, the result might not be the Kitchen, but likely the Blender, Refrigerator, and Microwave.

You let interns pull your strings?

apparently that's what happens when you use == where you meant object.Equals()
God bless .NET
the string.Interns aren't even cute.

I've never used that feature of .Net, mostly because I wasn't aware that it even existed, but now that I know, I can't think of any code I've written in the past 13 years that would actually benefit from it.

it's not that it benefited from it, but my code was getting artifacts because of it.
calling string intern simply allowed me to verify the nature of the problem.
The problem is this - and it's rare, in practice, but it smacked me right between the eyes:
say i have an identifier of type *object* - yes, object
and i need to compare it with other identifiers of object.
This works as expected with object.Equals, but not with ==
The latter strictly does reference comparisons.
This introduces a weird thing with strings.
check this out
object id = "foo";
object foo = Console.ReadLine(); // type "foo" into this
if(id==(object)"foo") ;// evals to true
if(foo==(object)"foo") ;// evals to false!
if(id==foo) ;// evals to false
if(Equals(id,foo)) ;// evals to true

not in this case. i fixed it.
the symbols are object for very specific reason and i don't need such a general case comparison. They will be integer, or string, or in one case a very custom type that is only handled in one scenario.
it's weird, but the algorithm behind it is such that the weirdness is unavoidable.
