3. How to construct an abstract syntax tree - Stack Overflow

   stackoverflow.com/questions/1721553

   To construct the parse tree from a grammar and an expression, you would first have to convert your grammar into working code. Typically, you would split the work into a tokenizer which splits the input stream representing the expression into a list of tokens, and a parser which takes the list of tokens and constructs a parse tree\ast from it.

4. abstract syntax tree - AST from C code - Stack Overflow

   stackoverflow.com/questions/239722

   You can try generate AST (Abstract Syntax Tree) using Lexx and Yacc on Linux: lex and yacc. from lex and yacc to ast. answered Oct 27, 2008 at 14:19. milot. 1,060 2 8 17. The problem would be to have a rather complete lex grammar for C which is not an easy task due to the C preprocessor, typing rules etc. – Remo.D.

5. Create Syntax tree from given Regular Expressions (For RE to DFA)

   stackoverflow.com/questions/26948724

   3. I'm learning Automaton Theory and facing some difficulties for converting a RE directly to DFA. This method requires to create syntax tree from the RE. But i am not able to generate. I am given a regular expression e.g a*b*(a|b)abc. Now i want to generate a syntax tree from this. I don't want program for it but i want to do it manually.

6. Generate syntax tree for simple math operations

   stackoverflow.com/questions/2705727

   I am trying to generate a syntax tree, for a given string with simple math operators (+, -, *, /, and parenthesis). Given the string "1 + 2 * 3": It should return an array like this:

7. Constructing an Abstract Syntax Tree with a list of Tokens

   stackoverflow.com/questions/25049751

   At each incremental step, there is an opportunity to build part of the AST by combining AST fragments built by other incremental steps. This is a recursive idea, and it bottoms out in building AST leaf nodes for tokens as they are scanned. This basic idea occurs in pretty much all AST-building parsers. If one builds a recursive descent parser ...

8. algorithm - Generate an AST in C++ - Stack Overflow

   stackoverflow.com/questions/28530284

   For example, if your program can consist of a series of statements, where each statement can be either a function declaration or a function call, you could create the following data structures: AST (struct) -> std::vector<Statement*> statements. StatementKind (enum class) -> Function. -> Call. Statement (struct)

9. abstract syntax tree - Getting AST for C++? - Stack Overflow

   stackoverflow.com/questions/9022913

   8. Actually, GCC will emit the AST at any stage in the pipeline that interests you, including the GENERIC and GIMPLE forms. Check out the (plethora of) command-line switches begining with -fdump- — e.g. -fdump-tree-original-raw. This is one of the easier (…) ways to work, as you can use it on arbitrary code; just pass the appropriate CFLAGS ...

11. Abstract Syntax Tree generator for javascript, but available in...

    stackoverflow.com/questions/24829135

    2. I was using the esprima AST generator for javascript and using node.js. It works great! Now I need to process the resultant json and would really like to use groovy - I have used groovy for this very successfully in the past. I could use two passes (first use node to create the json files and then use a groovy script to process them).
