I have some reasonable (not obfuscated) Perl source files, and I need a tokenizer, which will split it to tokens, and return the token type of each of them, e.g. for the script
print "Hello, World!\n";
it would return something like this:
Which is the best library (preferably written in Perl) for this? It has to be reasonably correct, i.e. it should be able to parse syntactic constructs like qq{{\}}}
, but it doesn't have to know about special parsers like Lingua::Romana::Perligata. I know that parsing Perl is Turing-complete, and only Perl itself can do it right, but I don't need absolute correctness: the tokenizer can fail or be incompatible or assume some default in some very rare corner cases, but it should work correctly most of the time. It must be better than the syntax highlighting built into an average text editor.
FYI I tried the PerlLexer in pygments, which works reasonable for most constructs, except that it cannot find the 2nd print
keyword in this one:
print length(<<"END"); print "\n";
String

You can tokenize source code using a lexical analyzer (or lexer, for short) like flex (under C) or JLex (under Java). The easiest way to get grammars to tokenize Java, C, and C++ may be to use (subject to licensing terms) the code from an open source compiler using your favorite lexer.
Steps to tokenize assets: Selecting an asset to tokenize, creating a tokenomics model, choosing a blockchain platform for asset tokenization, developing smart contracts, crypto wallet integration, token launch for trading on primary and secondary markets.
Tokenization in simple words is the process of splitting a phrase, sentence, paragraph, one or multiple text documents into smaller units. 🔪 Each of these smaller units is called a token. Now, these tokens can be anything — a word, a subword, or even a character.
Tokenization is the process of replacing sensitive data with unique identification symbols that retain all the essential information about the data without compromising its security.

Yes, only perl can parse Perl, however PPI is the 95% correct solution.
