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

Apologies for posting a flex++ question rather than a C++ question, but
there does not appear to be a flex++ newsgroup...
I am trying to rebuild some old lexical scanner / analyzer code,
which I believe was generated by flex++/bison++.
The rebuild is required because existing code is only a 7-bit scanner
(uses char rather than unsigned char as its character type, and the
tables only go up to 127) and I need to work with 8-bit input.

Hello,
is there a way to feed an ifstream to a parser generated with flex and
bison? I could see that flex wants a FILE* for reading, but I only
have an ifstream (actually and ifstream*) for input.
It seems that flex++ can use an ifstream; but how does the generated
lexer then work with bison?
Or is there a (portable) way to get a FILE* from an ifstream?
Thanks in advance,
Oliver Gerlich

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

Can any one let me get started?

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

Hi Everyone,
Still a newbie with FLEX, and I've passed arrays using AJAX to FLEX before, but I've never passed links to FLEX.
Basically, this is the OUTPUT, which I wanted, but I'm given an error of "illegal character," from the JavaScript console:

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?

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:

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
