Hi,
I am looking for a Python equivalent of Flex. After some
browsing, it seems that Plex is my best bet, but I would like to
hear suggestions before I dive in.
I have been using Flex a lot in combination with C programming.
I never use Yacc (or Bison), though Flex and Yacc are supposed
to be used together. But I found Yacc too cumbersome, and
unnecessary. Yacc is about context-free grammars, nice if you

Hi!
We are finding ourselves in a situation where we have to parse
several more or less free format text files.
In the past, on linux, we had flex and bison for generating
very fast parsers for these files.
Is there any equivalent in the visual studio world?
Lots of Greetings!
Volker

Guys,
I've been designing applications for the financial services industry using
MSFT technologies for many years (Win32 API, MFC, and now .NET WinForms).
All applications are Internet-based, with a "thick client" which makes calls
to my grid of servers via a socket or remoting connection.
Customers are pleased with my work but it seems that over the past twelve
months or so, those same customers have expressed a strong demand to...

I am writing a parser to handle input commands and process them. There are some builtin in commands that it will recognize one of which is TOK_CMD with another keyword after it (all tokenized based on supported commands).
The processing is working great for real commands, so moving on to error detection. I have the rule:
| TOK_CMD error TOK_EOL
{
printf ("illegal command dummy\n");
}
| error TOK_EOL

I am trying to contribute to a large project and am running into a bit
of a problem.
One of the lex files uses %option reentrant, which flex refuses to
compile. I am running version 2.5.4 under windows. From what I can
gather, this is a rather old version, but I have not been able to find
newer binaries.
Is there a download out there for version 2.5.33? Also, can someone
confirm that %option reentrant works with 2.5.33?

I'm currently working on a laguange similair in concept to Vala
(google for it on the Gnome project site). A (very) high level
language is translated into intermediary C, which is then
compiled to target.
I want to be able to "include" C headers, so that I don't have to
write bindings. That however means, that I have to parse them. I
could now of course write my own Flex / Yacc code, but I
presume, that there are ready to use C parser...

Hello to all,
I've been using C for a long time however I'm about to take my first
splash into making a parser. I have some interesting things to

I will be parsing a configuration file, like this:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
