What would be the bast way to get parsing and validation of parameters (option:value)

Need to parse and validate user supplied parameters for video encoders, in the form of "\--option1:value --option2 --option3:value", which are unique for each encoder we have defined. option fields must be in a set of predefined such fields, while values have to be in a certain range for integer

Trying to make a lexer, stops if it hits an operator.

Why ignore whitespaces/newlines ? You need this kind of info. What you want is to skip tokenizing the char itself but at the same time will store whitespace and line number in a tuple, for each `getToken` call TokenTuple* = tuple[kind: TokenKind, value: string, wsno, line, column: i

OpenSSL/DTLS Support in Nim

@federico3 Ah, that's a shame, but understandable. Thanks for the links! The TFTP protocol provides a basic retransmission scheme. I believe the authors chose UDP because it was the simplest available, though it's not a requirement. I could switch to TCP, but I'm enjoying figuring this all out

strutils: mapIt: empty seq gives index error

Yes, its an issue with min. My apologies for time wasting. I just refer you to the last line of my op.

Thanks for the feedback. my comment came from this if myNewTracks.len > 0: var myTrackMin: int = myNewTracks.mapIt(it.len).min - 1 if myTrackMin < myMin: myMin = myTrackMin Run where myNewTracks is a seq[seq[Coord]]

Ttop - System monitoring service tool with tui and historical data

I see graphs, historical data, and I wonder if you're considering to extend the utility to monitor sensors data. When I was trying to underclock my Alder Lake CPU I found very few Linux utilities (s-tui) that track thread/core temp/utilization/throttling, especially for processors with >20 threa

OpenSSL/DTLS Support in Nim

That's not enough, the client and server need to negotiate the secret key to be able to use encryption (or better AEAD, authenticated encryption). In libsodium that's in the key exchange session: Note that creating protocols like this is the dangerous p

You can implement encryption using but doing file transfer over UDP would require implementing retransmission and ideally also congestion control.

Hi, I have a quick question about `BaseLexer` `open` method in `std/lexbase`, that given your experience on the topic you may have an answer for. It seems that the lexer is optimized for line based parsing? What is the best idiomatic way to parse a language that can ignore new lines? Currently f
