How to provide input file for Flex++?
I am using Flex++, which is Flex for C++ and I am having trouble setting the input file. Flex++ uses the FlexLexer class provided in FlexLexer.h to create the lexer object(https://github.com/westes/flex/blob/master/src/FlexLexer.h). In my main function I have

Do Regular Expressions only evaluate one line at a time?
Further applications of DFA and NFA: lex or flex, yacc or bison, and POE :-)

Cool C projects
How about writing a programming language using Flex and Bison? There are lots of good tutorials and examples out there.
-
Parser and Lexer bike-shedding
Some lexer generators (notably Flex) take input from a file handle by default. While you can always read a file into a string before passing it to the generated lexer, this is not seen as "the best" since you have to read in all the data into memory, which can be a lot.

A Good Tool for Resuming Parsers?
Ages ago, I loved writing domain-specific toy languages, and almost always used flex to generate lexers and GNU bison to generate the parser. I've begun a new toy project and I don't think those two will cut it this time, so I'm looking for other tools that integrate well with C++.

Please no
I don't understand :c don't lexers like Flex work off of regex rules? Isn't this the correct first step to parse it?

A work in progress C compiler from scratch
I wrote a C compiler using flex [1] and bison [2]. The glue between them is a bit hacky.
At some point ANTLR [3] looked promising, but these days I'd probably write a lexer and recursive descent parser by hand, then generate LLVM IR.

Dealing with lex and yacc is DIFFICULT so little information is available about them!

Qual’è il commento più assurdo che avete mai trovato nel sorgente di un software?
Un commento in flex, uno storico software, tanto per mostrare che anche i migliori fanno le cose alla buona.

DjHTML 3.0.0 has been released
We are happy to announce that DjHTML 3.0.0 has been released! This source code formatter for Django templates correctly indents mixed HTML/CSS/JS templates, including Django template tags, and can easily be used as a pre-commit hook to automatically indent Django templates on every commit.

null-ls not detecting djhtml
~ djhtml -h usage: djhtml [-h] [-i] [-c] [-q] [-t N] [-o filename] [filenames ...] DjHTML is a fully automatic template indenter that works with mixed HTML/CSS/Javascript templates that contain Django or Jinja template tags. It works similar to other code-formatting tools such as Black and interoperates nicely with pre-commit. Full documentation can be found at https://github.com/rtts/djhtml positional arguments: filenames input filenames options: -h, --help show this help message and exit -i, --in-place modify files in-place -c, --check don't modify files -q, --quiet be quiet -t N, --tabwidth N tabwidth (default is 4) -o filename, --output-file filename output filename
