you mean add a bot to top.gg? you go to the website and add it there
i did

hmm yea but it have both
shapes - ai

i am only using shapes for ai
rest it have cmds
prefix cmds
quartz kindle
then make sure to remove anything that says its from shapes
untold vortex
then make sure to remove anything that says its from shapes
umm ok
quartz kindle
and removing anything that makes it look like its a copy of shapes
quartz kindle
like for example, often people copy other bot's code
and forget to change basic stuff like help command

and when you run the help command, you see the help command for a bot with a different name
that happens a lot

it makes sense because it's technically not a type thing it's an actual operator
string balls = "";
if (dict.TryGetValue("balls", out balls!)) {

``` so you could do thatbut it takes an expression as an input not a type like ? does
if (dict.TryGetValue("balls", out string? balls)) {
balls!.ToArray();
}
that's your other alternative
if (dict.TryGetValue("balls", out string? balls)) {
if (balls is null) throw new NullReferenceException();
balls.ToArray();
}

hello peepers, I have a question on how I should handle evaluations.
I have multiple maps with different formulas. I have to query the maps for the formula I am wanting to use and then call an Evaluate method to evaluate the math expression.
As it stands now, I think it is messy with how I am doing it, as I don't want to make multiple evaluate methods to handle roughly the same code as all i'd be doing is changing the depth of the decimal place depending on what formula is being evaluated.
My first idea was to just have a depth field and a key field in the evaluate method, and just query the dictionary based on the depth and key but I am not sure.
public static string Evaluate(string key, string expression, int depth = 2)
{
if (depth == 2)
{
// Grab from the TempertureFormulas dict using the `key`
Expression express = new Expression(expression);
var result = express.Evaluate();
return Convert.ToDouble(result).ToString("F2");
}
else if (depth == 4)
{
// Grab from the UnitFormulas dict using the `key`
return Convert.ToDouble("1234").ToString("F4");
}
return "NaN";
}
This seems extreamly messy, as once I start multiple different points of conversions besides Units of Measurements & Tempertures it will get rather weird to handle, as not every conversion makes sense to have say 2 decimal places, or 4 decimal places.
This is C# btw

lyric mountain
u want to have automatic precision no?
sharp geyser
Not really (kind of)
lyric mountain
then I read it wrong, lemme reread it
sharp geyser
I can just summarize it
Essentially I want to find a way to easily evaluate based off any expression. I have maps of formulas for different types of conversions. E.g Formulas for temp conversion, and also units of measurements. Problem is, each different formula requires different decimal precision (so ig you are right I am looking for automatic precision) but I also I am finding myself writing lengthy if statements to make sure I am evaluating the appropriate formula, which is not ideal.
lyric mountain
oh, well, can't u just have a dict of precision <-> classes?

How do you mean?
lyric mountain
{
1: Class1,
2: Class2,
3: Class3,
}
for precision 1, use Class1
for 2, use Class2
and so on
sharp geyser
lyric mountain
then just dict[depth].SomeInterfaceMethod(expression)
sharp geyser
Well, automatic precision is probably better than doing it that way ngl
My issue is, I have multiple dicts of different formulas
public static Dictionary<string, string> TempertureFormulas = new Dictionary<string, string> {
{ "CF", "(C * 9/5) + 32" },
{ "CK", "C + 273.15" },
{ "FC", "(F - 32) * 5/9" },
{ "FK", "(F-32) * 5/9 + 273.15" },
{ "KC", "K - 273.15" },
{ "KF", "(K - 273.15) * 9/5 + 32" }
};
public static Dictionary<string, double> UnitFormulas = new Dictionary<string, double> {
{ "FM", 1 } // Feet to Meters
};
I have yet to fully write out the UnitFormulas dict, but the gist is, I will end up having to query each dict and then grab the formula, replace the placeholder and evaluate it
Which can get messy
For example,
/feet can convert feet to numerous amounts of measurements, Centimeters, Meters, Kilometers, Miles, etc etc
I'd have a big chain of if/else if statements
That seems not ideal
lyric mountain
var dicts = {
2: TempertureFormulas,
4: UnitFormulas,
}
...
dicts[depth][key]
That could work yes
I was using TryGetValue simply because its the "safer" method
lyric mountain
nope
sharp geyser
wym nope
lyric mountain
tryget the depth
lyric mountain
then check if key returns null
btw, it'd be easier for u if u used a yaml file for it
sharp geyser
oh right
sharp geyser
Guess I can't use dynamic here
It can't convert the Dictionary Types to string, dynamic
lyric mountain
btw, it'd be easier for u if u used a yaml file for it
for this u could declare it like ```yaml
temperature:
CF: "(C * 9/5) + 32"
CK: "C + 273.15"
FC: "(F - 32) * 5/9"
FK: "(F-32) * 5/9 + 273.15"
KC: "K - 273.15"
KF: "(K - 273.15) * 9/5 + 32"
unit:
FM: "1"
it cant?
sharp geyser
nope
lyric mountain
well, then use object
sharp geyser
Same thing
lyric mountain
then smth is wrong
sharp geyser
@scenic kelp C# person, explain :D
lyric mountain
I've used maps with dynamics and objects before
sharp geyser
The best overloaded Add method 'Dictionary<int, Dictionary<string, dynamic>>.Add(int, Dictionary<string, dynamic>)' for the collection initializer has some invalid argumentsCS1950
Argument 2: cannot convert from 'System.Collections.Generic.Dictionary<string, string>' to 'System.Collections.Generic.Dictionary<string, dynamic>'
I guess its due to mainly this
sharp geyser
I don't understand the use of var tbh
lyric mountain
oh wait, how are u applying it?
lyric mountain
I don't understand the use of var tbh
to not declare it twice
sharp geyser
lyric mountain
well, yes u cant do that
lyric mountain
lmao
sharp geyser
so dynamic is just like "Idk the type rn, figure it out at runtime" ?
sharp geyser
gotcha
lyric mountain
btw I do recommend setting up a yaml structure like I mentioned before
it'll be easier for u and reduce boilerplate
sharp geyser
I will eventually
Right now I jsut want a proof of concept
😭
I also dk how to read yaml files in c#
sharp geyser
https://github.com/aaubry/YamlDotNet
Should I make my own math parser instead of using NCalc?
I mean, I can use NCalc, but I am only wondering because I am noticing I am basically repeating other expressions inside an expression
like to convert K to F, I have to first convert K to C, then C to F
tempeture:
CF: "(C * 9/5) + 32"
CK: "C + 273.15"
FC: "(F - 32) * 5/9"
FK: "(F-32) * 5/9 + 273.15"
KC: "K - 273.15"
KF: "(K - 273.15) * 9/5 + 32"
KF -> KC * CF
Idk if thats something I should care about
but readability wise maybe?
I don't know
lyric mountain
I don't know <:Hmm:852725633368457266>
do it for readability, the runtime will unwrap it anyway
sharp geyser
CK is wrong btw
no
1 Celsius = 274.15
so that math is correct
2 C = 2 + 273.15 = 275.15
sharp geyser
do it for readability, the runtime will unwrap it anyway
Hmmmm, problem is idek how i'd do it myself 😭
I'd need to grab the other formulas and pass in the appropriate values
I'd like to figure out how to make my own parser
eternal osprey
Who wants to beta test my AI training power usage and efficiency metrics 
Spent a whoppin 2 weeks on that bitch

I still haven't been able to touch the ai model you made for me
💀
Got super busy with family, and then another project grabbed my eye
sharp geyser
Sorry man 😔
scenic kelp
<@172075838806818817> C# person, explain :D
why jn god's name are you using dynamic
sharp geyser
disprespecting my work like that
I'd like to get back to work on that project
AI is just wayyyy over my head
Idek how to read the code you wrote
scenic kelp
also you just can't use dynamic as type arguments
because dynamic doesn't have a specific size
generics are a compile time mechanism and dynamic is a runtime one
eternal osprey
AI is just wayyyy over my head
I can help ya out nw.
I will explain the code step by step once i am done with some projects.
sharp geyser
sharp geyser
Yup
eternal osprey
You can actually make it better using GloVe or whatever it's called but the download process was hella slow so i gave up.
sharp geyser
I played around with it a bit but got busy
eternal osprey
Yeah, you can change the hyperparameters as well, but iirc i applied gridsearch on it to find the "most optimal" tuning.
scenic kelp
also you should realistically never be using dynamic in actual C# code
the only time dynamic should ever be used is interfacing with other .NET languages that are dynamically typed
sharp geyser
so its quite literally just a placeholder
and it takes on the type depending on whats passed to it
but at compile time thats not good right?
scenic kelp
generics are static placeholders, i.e. compile time ones, whereas dynamic is a runtime one
it defers type checks to the run time
quartz kindle
dynamic = js
sharp geyser
scenic kelp
there's technically a couple of types in C# that don't inherit from System.Object
i'm sure those would fuck it up
if you're really doing scuffed things, just use object
scenic kelp
math parsers are pretty simple
scenic kelp
no they are like objectively the easiest type of parser to make
you could technically get away without tokenizing first but a good first goal would be to make a tokenizer
sharp geyser
tempeture:
CF: "(C * 9/5) + 32"
CK: "C + 273.15"
FC: "(F - 32) * 5/9"
FK: "FC + 273.15"
KC: "K - 273.15"
KF: "KC * CF"
My only goal is to support nested formulas such as KF
scenic kelp
something that converts like
2 + 3 * (4 / 2)
into
Number(2) Operator(+) Number(3) Operator(*) LParen(() Number(4) Operator(/) Number(2) LParen()) EOF()
then you write parser rules using those tokens which is a lot easier than having to deal with raw characters
your parser takes the token stream and makes a tree
then to evaluate your expression you visit every node in the tree and evaluate that
number nodes evaluate to their value, operator nodes operate to value of lnode op value of rnode
scenic kelp
that expression has a tree like that
sharp geyser
so idek where to start
scenic kelp
group your objects into tokens and think in terms of a grammar
operators like +, -, *, / operate on two values
sharp geyser
Right theory I understand, but programming no.
scenic kelp
so they're binary operators, we can define them in a grammar as
expression binary_op expression
sharp geyser
I guess first step is just taking in an expression
sharp geyser
Then looping over that expression, breaking it up, and tokenizing it
scenic kelp
you want to tokenize first
anyways your expressions will basically be either a binary operator expression, a number, or another formula
so start with that, your tokenizer should be pretty simple
you just loop over your input and output tokens for numbers, operators, and formulas
sharp geyser
C# has enums right
scenic kelp
yes, i normally use static strings though
scenic kelp
better for interop and printing etc
scenic kelp
it's a personal preference but you incur a quite significant performance cost when you stringify enum values into their names etc
sharp geyser
How exactly would static strings work
scenic kelp
which doesn't matter in the end but also you incur a huge portability cost
just a static class
class Token {
public string TokenType { get; init; }
...
static string TOKEN_PLUS = "Plus";
static string TOKEN_MINUS = "Minus";
}
``` or just build it into the token classyou're technically losing some type safety
but i've never had it be an issue
scenic kelp
init is a setter that only lets it get set once in the constructor
scenic kelp
yes
class Token {
public string TokenType { get; private set; }
...
static string TOKEN_PLUS = "Plus";
static string TOKEN_MINUS = "Minus";
}
and that means it can only be set inside the class Token right?
scenic kelp
yep
sharp geyser
or can it also be done in inherited classes
scenic kelp
not with private
scenic kelp
now technically that is probably the most performant way of writing a lexer
but yknow
scenic kelp
state machines are not exactly super readable
quartz kindle
literally maximuim 3 depth
scenic kelp
yeah
scenic kelp
don't do that, performance will be more than acceptable with a basic lexer
sharp geyser
Right parm
scenic kelp
typically i build pretty 'stupid' state machines but with a switch in the main parser method
then call other methods for processing things like strings and numbers
sharp geyser
do you know any articles I can read to do this
or should I literally just go with the flow
sharp geyser
😔
scenic kelp
if you have any questions or get stuck i'm here
scenic kelp
until my lens adapter gets here then i'm going and taking photos but
quartz kindle
i just made a bunch of switch cases to handle every possible string combination
this is what my data looks like, its not much different from what you have
scenic kelp
oh god
sharp geyser
- Tokenizing - Grabbing the expression, breaking it down using some kind of split method and then tokenizing the individual components
- Parsing it and evaluating it?
scenic kelp
parsing and evaluating are technically separate steps
easier that way, you could technically combine them but
the pipeline is quite flexible depending on what you're writing
but otherwise yes, your tokenizer takes a complex stream of characters and abstracts it into tokens
which makes your parser MUCH simpler because it can operate on much more well-defined inputs
scenic kelp
you can use enums i was just saying i personally prefer strings in most cases
sharp geyser
ignore me
scenic kelp
if you wanted to be really cool and awesome you could also use derived classes from a Token base but
that's too much work for my shitty lexers
your token class basically just needs to store the character content and the type
sharp geyser
class Token
{
public string TokenType { get; init; };
static string TOKEN_PLUS = "Plus";
static string TOKEN_MINUS = "Minus";
static string TOKEN_DIVIDE = "Divide";
static string TOKEN_MULT = "Mult";
static string TOKEN_LPAREN = "LParen";
static string TOKEN_RPAREN = "RParen";
}
Then I can have a Tokenizer class that has a dictionary of tokens, and then that would have a method that takes in a expression, breaks it down into components, and associates a token with that component and adds it to the dictionary right?
sharp geyser
ic
scenic kelp
it could probably work but
normally the easiest thing to do is just have a tokenizer class with a method that takes in a string and returns a List<Token>
sharp geyser
I see
scenic kelp
you're basically writing a state machine
sharp geyser
really?
eternal osprey
using c/c++ as oop should be a crime
scenic kelp
i would have looked very uncredible
C++ was literally designed to be object oriented wdym
sharp geyser
then why do ; after TOKEN_PLUS
eternal osprey
nah java on top
scenic kelp
you need that
sharp geyser
but its a property
sharp geyser
scenic kelp
ok so
sharp geyser
whats the difference between TokenType and the rest?
scenic kelp
if there's no { get; set; } bullshit going on
it's a field
otherwise it's a property
sharp geyser
What is the difference between a property and a field then
scenic kelp
properties are just a really convenient shorthand for getter and setter methods
eternal osprey
Aaron is always internally fighting for his life when learning new things 😭
sharp geyser
cuz I always used the both interchangeably
scenic kelp
so we're not doing the java thing of having fucking ugly code
eternal osprey
so we're not doing the java thing of having fucking ugly code
sharp geyser
Aaron is always internally fighting for his life when learning new things 😭
I learned programming in an unorthodox way, so learning new concepts is not the easiest for me.
scenic kelp
String thing;
String getThing() {
return thing;
}
void setThing(String thing) {
this.thing = thing;
}
i am not clowning you btw, or calling you out. Just something i found funny to see hahah
scenic kelp
string thing {get; set;}
me myself, i am also always on the verge of suicide when learning new concepts
scenic kelp
which is cleaner
sharp geyser
It takes me a sec for my brain to click what is being said to me.
scenic kelp
let's not talk about the full form for C# properties because it's just as bad
string _thing;
string Thing
{
get { return _thing; }
set { _thing = value; }
}
basically that's what the { get; set; } does for you automatically!
sharp geyser
icic
scenic kelp
now the motivation behind using properties is iffy but basically a) you get better access control and b) you can do validation in the setters
a) is very valid, literally never done b)
oh and because they're methods they're part of the public interface of your class so that's your c)
scenic kelp
i would say no because you can keep the input and output as instance variables
it's a design decision basically
sharp geyser
i would say no because you can keep the input and output as instance variables
public List<Token> Tokenize(string expression)
{
List<Token> tokens = [];
string[] components = expression.Split(" ");
for (int i = 0; i < components.Length; i++)
{
// Somehow create the token?
}
return [];
}
Sad to say I am stuck already 😭
TokenType I assume would be one of the TOKEN_PLUS type stuff right?
So a Token would have TokenType and Value right?
scenic kelp
yes
sharp geyser
So I would have to do something like
Also, wait
since the static fields are private how do I create the token?
scenic kelp
oh right yeah they need to be public
sharp geyser
Oh bout to say
scenic kelp
i noticed that before but i forgot to correct myself oopsies!!
scenic kelp
i'm so not used to the new list initializer syntax it feels so weird to me
sharp geyser
How should I determine the token type?
Side note, this is kind of making me want to make my own language
💀
scenic kelp
see that's what i'm saying
anyways for that you can basically instantly feed your operators into a token
you've only got numbers and formulas now right, so if the first character is a number it must be a number
you can blindly trust that or you can do a sanity check and check the other characters in the string to make sure
sharp geyser
Right, but how do I determine that its a number, or its a +, -, /, *
scenic kelp
well you have the string
also actually you might be better off looping over the characters rather than using split
think of the case where you have like --2 (we don't have unary operators yet but)
it should be tokenized as Minus(-) Minus(-) Number(2)
sharp geyser
Right
But my main concern is, yes I have the string, but how exactly do I determine its a minus
or its a plus
class Token
{
public required string TokenType { get; init; }
public required string Value { get; init; }
public static string TOKEN_PLUS = "Plus";
public static string TOKEN_MINUS = "Minus";
public static string TOKEN_DIVIDE = "Divide";
public static string TOKEN_MULT = "Mult";
public static string TOKEN_LPAREN = "LParen";
public static string TOKEN_RPAREN = "RParen";
public static string TOKEN_NUMBER = "Number";
}
because the prop names aren't exactly easy to determine as such
How would I go from
"2 + 2" -> Number(2) Plus(+) Number(2)
scenic kelp
you check in your method
scenic kelp
with a switch or an if
scenic kelp
```cs
class Token
{
public required string TokenType { get; init; }
publ...
look at you all fancy using required
scenic kelp
when you initialize a class with
Token t = new Token { TokenType = Token.TOKEN_PLUS }
``` it would give you an errorbecause you're missing Value
scenic kelp
null safety yeah
because nullability was shoved into the language only a couple of years ago
sharp geyser
Ok
so I have a general idea on what to do now
switch (components[i]) // or would it be the typeof? idk {
case "+": {
// create the plus token
}
}
idek how i'd handle numbers
if I was to go based on typeof, i'd need a nested switch right?
well no
scenic kelp
typically in that case when i read a number i'd create a different method in the tokenizer class that's PURELY for reading that number
sharp geyser
nvm
sharp geyser
typically in that case when i read a number i'd create a different method in the...
I'd like to start out doing it all in one place for now
Splitting it off and making it more readable comes later
scenic kelp
then you'd just use a different loop
sharp geyser
lest I confuse myself
scenic kelp
are you still using a for loop with the split actually
sharp geyser
as of rn yes
sharp geyser
error resilience?
scenic kelp
you could just see the first character is a number and go "yeah that means this is a number"
but obviously 123NUMBER is not a number
sharp geyser
I'd like to go the route that makes the most sense
and is in line with "proper" procedures
scenic kelp
imma keep it real with you i have no idea what is proper
i just have my own bones for it
scenic kelp
i think it's easier to loop over the characters without splitting them because then you can handle cases like ++
and then it also makes it easier to, when you read a number, call a different method specifically for handling reading a number
scenic kelp
it has its own while loop and only consumes the parts so 123NUMBER would get parsed as Number(123) Identifier(NUMBER)
i always use a while loop and manually advance it
sharp geyser
just
for (int i = 0; i < string.Length; i++ ) {}
```?cause then it lets me easily call other methods to do other parsing
scenic kelp
it's a bit more error prone because you have to remember to advance them but
for loops are just sugar over while loops
for (int i = 0; i < s.Length; i++)
{ ... }
``` is just sugar for
```cs
int i = 0;
while (i < s.Length)
{
...
i++;
}
like for example with plus
...
case '+':
tokens.Append(new Token { Value = input[i++], TokenType = Token.TOKEN_PLUS);
break;
notice how i use i++
(in reality i should be a class property and not a local variable so you can advance from the other methods but)
sharp geyser
I didn't know you could do that
How exactly does that work in the case of starting where you left off in other methods?
For example, I have a method for parsing a number, I call it parse that number, and then now I return back to the main method and parse the plus
scenic kelp
class Token {
int pos;
}```how do I now to start after the number
scenic kelp
your number method takes care of that
you can do something like,
- store the starting position
- iterate until the next character is no longer a number
- get the substring and create a new token
- advance the position to the end point
- return the token back to the call point in the main method
sharp geyser
you can do something like,
1. store the starting position
2. iterate until the n...
Sorry to bug you
but I have another question 
scenic kelp
😡🤬🤬🤬😡🤬🤬🤬😡🤬🤬🤬🤬
sharp geyser
sorry ;c
scenic kelp
my reaction to being pinged on discord
sharp geyser
sorry
scenic kelp
anyways ask away!!!
sharp geyser
I am working on parsing numbers first, since that seems the hardest.
I made a prop called startingPos on the Tokenizer class to keep track of the position to start at. Now, when calling the TokenizeNumber method I made which handles tokenizing the number, I need to take in the expression used, and then loop over it at that startingPos and once I reach something that isn't a number, update that startingPos and exit the function returning the new Token correct?
scenic kelp
nah you'd want to keep it in the method since you only care where it starts in the method
like in your method you just keep track of int start = pos
scenic kelp
yeah, that's what the pos is for on your class
that way, when you're done in the number method pos is advanced past the number token
sharp geyser
I am confused
Is that not what I am doing?
class Tokenizer
{
int startingPos = 0;
public List<Token> Tokenize(string expression)
{
List<Token> tokens = [];
while (startingPos < expression.Length)
{
char currentItem = expression[startingPos];
if (Char.IsDigit(currentItem))
{
tokens.Append(TokenizeNumber(expression));
}
switch (currentItem)
{
case '+':
{
tokens.Append(new Token
{
TokenType = Token.TOKEN_PLUS,
Value = currentItem,
Position = startingPos
});
break;
}
}
}
return tokens;
}
Token TokenizeNumber(string expression)
{
}
}
blah blah 23 + 2
^
``` that's the position when you go into the functionblah blah 23 + 2
^
``` that's the position when you exit itso that the next loop of your main function, it reads the whitespace after
sharp geyser
I think I may be doing it entirely wrong then
cause that above is how I am currently calling my TokenizeNumber method
and how I plan on treating it
scenic kelp
you can rename startingPos to pos
the startingPos in your tokenize is just a temporary measure so you know where to take the substring from
sharp geyser
so have int pos = 0 at the class level, and then inside the Tokenize method have int startingPos = pos?
scenic kelp
yeah
then you're literally only using it when you make the token so you can take the substring
sharp geyser
so even in the Tokenize method I am updating pos right not startingPos?
scenic kelp
yep
sharp geyser
scenic kelp
pos is basically where the current token you're reading is
it's the cursor in your text editor
sharp geyser
right but how would that work
scenic kelp
think of it like that
sharp geyser
int startingPos = pos sets the current value of pos
so updating pos doesn't update startingPos does it?
sharp geyser
oh?
scenic kelp
then you take a substring from startingPos to pos
think of it as a text editor analogy
you've got a math expression open in notepad
and you're really stupid or something and can only read the one character your cursor is at
when you see a number, you go ahead and start highlighting it
we're "highlighting" it by recording the position at which it starts, and we already know the position where it ends because we know the next character isn't a number at pos
bad analogy but whatever
i thought it was better when i started it
sharp geyser
I get it
so should I still be passing in the entire expression or should I pass in only from the starting position to the end of the expression to the TokenizeNumber method?
scenic kelp
you don't pass anything into your tokenize method
because all the data it needs is on the class
scenic kelp
the input string, and the current position
sharp geyser
How exactly are you envisioning this
scenic kelp
(which you should make the input string a class field btw)
sharp geyser
because what I am doing is passing in the expression to the Tokenize method
scenic kelp
true
you should probably move that to the constructor
it would only really make sense to pass it directly to the tokenize method if it were static
scenic kelp
yeah
sharp geyser
and when I am calling the TokenizeNumber method, I make a substring inside it of the current position and the end of the expression and loop over that?
scenic kelp
the end of the number specifically
sharp geyser
scenic kelp
because your goal is to find where the number ends
that's what that method does
it knows where it starts, because it got called
sharp geyser
How do I know the end of the number without looping over it first
sharp geyser
right...I guess I am not explaining what I am saying properly
scenic kelp
that method has its own little loop
sharp geyser
yea
scenic kelp
start point = current position
while current position is number:
current position++
number = input.substring(start point, current position)
return the token
``` there's the pseudocode probably with 2 different off-by-one errorsright
Token TokenizeNumber()
{
int startingPos = pos;
while (Char.IsDigit(Expression[startingPos]))
{
pos++;
}
string number = Expression.Substring(startingPos, pos);
return new Token
{
TokenType = Token.TOKEN_NUMBER,
Value = number,
Position = pos
};
}
This seems a little off
but this is what my brain came up with
My biggest concern is the while loop won't actually go beyond the startingPos will it?
so it'd just read one character and then move on to making the substring
scenic kelp
use pos instead of starting pos in the loop
sharp geyser
Token TokenizeNumber()
{
int startingPos = pos;
while (pos < Expression.Length && Char.IsDigit(Expression[pos]))
{
pos++;
}
string number = Expression.Substring(startingPos, pos - startingPos);
return new Token
{
TokenType = Token.TOKEN_NUMBER,
Value = number,
Position = pos
};
}
in the first
sharp geyser
huh
ah
nvm I understand what you mean
https://hatebin.com/suonpnrqcd I seemed to have caused an inf loop or something 
I was testing my current implementation and logging the results of Tokenize and it seems to hang and not finish as it never outputs the list of tokens
am I blind and missing something?
yea
I've caused some problems
It's just spamming the TokenizeNumber method
I see, its never moving past the 2
huh, how is the starting position 1
I solved it
in the Tokenize method I have no need to make a startingPos variable
I can just directly use pos
scenic kelp
yeah you don't need a startpos for tokenize
because that's the main one, you only need it for when you're doing things like you did in the number one
technically think of the main one as stupid, it doesn't really know how to parse anything other than your simple one-character tokens
it calls on other people to do that for you
your other methods
