I read several papers about creating LR(1) item sets, but none of them pertained to left recursive grammars, such as those used for parsing expression ...

I am trying to get operator precedence correct in a Treesitter grammar. Treesitter is a LR1 parser generator. I have a straightforward artithmetic gr ...

There is something I don't fully get about the LR(0). I'm trying to figure out when grammar is not LR(0). As I understand I build the LR(0) items auto ...

Can someone please explain to me why an LR(1) grammar that is not LALR(1) must have only reduce/reduce conflicts ...

By all accounts, LR(1) should be more powerful in every way compared to LALR(1) since LR(1) builds a canonical collection of LR(1) items, and LALR(1) ...

I wanted to make a reader which reads configuration files similar to INI files for mswin. It is for exercise to teach myself using a lexer/parser gene ...

Here is a QML grammar (extracted from https://github.com/kropp/intellij-qml/blob/master/grammars/qml.bnf): Is it LALR(1)? My program raises a reduc ...

I have the following grammar: I have computed the first and follow sets for this grammar and I would like to know if it is correct. Here is my solu ...

I'm confused on how to parse this grammar using LR(1): I'm aware there is left recursion but I was told it isn't necessary to remove it for LR(1). ...

I'm having trouble parsing the following grammar using the LALR method. I'm ok at the beginning, here is item state 0: (the , seperates the lookahe ...

For homework, I was given the following grammar: I computed it using LL(1) just fine. The first sets were: The follow sets were: When I made ...

I'm currently looking at two closure calculation examples using the tool at http://jsmachines.sourceforge.net/machines/lr1.html Example 1 Here, in ...

Given input with repeating BLOCKs, where each block has repeating BEGIN EVENT and END EVENT entries (END EVENT always follows a BEGIN EVENT): How d ...

I'm having trouble building the collection of sets of items for LR(1) parsers with a grammar containing epsilon productions. For example, given the fo ...

I've written a parser generator in Java, after a few bumps (an early version didn't particularly like left recursion for example), I managed to make i ...

I have coded a table driven LR(1) parser and it is working very well however I am having a bit of a disconnect on the stage of turing a parse into a s ...

For the given context free grammar: How do I rewrite the grammar so that it is LR(1)? The current grammar has shift/reduce conflicts when parsing ...

I have written a code in C to implement LR(1) parse table, however now I am facing a problem in printing the parse tree. How do we do that in C? The t ...

I'm currently having a look at GNU Bison to parse program code (or actually to extend a program that uses Bison for doing that). I understand that Bis ...

Where can I find a simple (as much as possible, but no simpler!) implementation of an LR(1) parser generator? I'm not looking for performance, just t ...
