"Every corpse on Mount Everest was once a highly motivated person"
-
I keep thinking of that as I work on my source generator for my Visual FA project. It's a lot of work and I have a long way to go before I can write an article or anything. Writing source generators for C# is difficult, especially in Visual Studio where your updated generation code doesn't always "take" until you exit and relaunch Visual Studio. I had to find that out the hard way, after hours of struggle. I've also got to learn to make NuGet packages, and probably something more than just a simple DLL or something. Here's what I have so far, and I'm quite happy with it. So far you can declare a regex matcher (one FARule) or lexer (multiple FARules, possibly with symbol names and ids):
using VisualFA;
partial class TestSource
{
// Declare a lexer. Here we specify the rules and the type of lexer
// as indicated by FARule attributes and the return type
// shared dependency code is automatically generated as needed.
// It won't be generated if your code references VisualFA.
[FARule(@"\/\*",Symbol="commentBlock",BlockEnd=@"\*\/")]
[FARule(@"\/\/[^\n]*", Symbol = "lineComment")]
[FARule(@"[ \t\r\n]+", Symbol = "whiteSpace")]
[FARule(@"[A-Za-z_][A-Za-z0-9_]*",Symbol="identifier")]
[FARule(@"(0|([1-9][0-9]*))((\.[0-9]+[Ee]\-?[1-9][0-9]*)?|\.[0-9]+)",Symbol="number")]
[FARule(@"\+",Symbol = "plus")]
[FARule(@"\-", Symbol = "minus")]
[FARule(@"\*", Symbol = "multiply")]
[FARule(@"\/", Symbol = "divide")]
[FARule(@"%", Symbol = "modulo")]
internal static partial FATextReaderRunner Calc(TextReader text);
}That causes the C# compiler, with the help of my source generator to generate all the code necessary such that you can do this with it:
var exp = "the 10 quick brown foxes jumped over 1.5 lazy dogs";
foreach (var match in TestSource.Calc(new StringReader(exp)))
{
Console.WriteLine(match);
}Which nets you this:
[SymbolId: 3, Value: "the", Position: 0 (1, 1)]
[SymbolId: 2, Value: " ", Position: 3 (1, 4)]
[SymbolId: 4, Value: "10", Position: 4 (1, 5)]
[SymbolId: 2, Value: " ", Position: 6 (1, 7)]
[SymbolId: 3, Value: "quick", Position: 7 (1, 8)]

I assume you've read Andrew Lock's 10-part series on writing source generators, particularly Testing an incremental generator with snapshot testing[^]? :)

Yep, and if he mentioned having to restart visual studio for your source generator code adjustments to take effect sometimes I missed it.

I don't know. I've met some pretty lazy people - I imagine they'd make lazy corpses.

I’ve given up trying to be calm. However, I am open to feeling slightly less agitated. I’m begging you for the benefit of everyone, don’t be STUPID.

Depends on how many George Romero movies you've watched, I suppose.

When we started Despair, we had a dream. To crush other people's dreams. But we knew, given our goal, we'd be in for a fight. After all, the Motivation Industry has been crushing dreams for decades, selling the easy lie of success you can buy. That's why we decided to differentiate ourselves- by crushing dreams with hard truths!
The difficult we do right away... ...the impossible takes slightly longer.

LOL, it may have come that way to me indirectly, as I read it on the Internet somewhere.
