The goal of the project is to independently design a very simple programming language and implement its compiler. The project covers all stages of source code processing, up to the creation of machine code. You should use tools to support the work of the compiler creator. The front of the compiler, i.e. lexical-syntactic analysis, should be done using the ANTLR analyzer generator or other similar tools. An intermediate representation (IR) should be generated from the resulting AST tree in a form consistent with the LLVM specification. The optimization of indirect representation as well as the generation of machine code will be performed by the tool available in LLVM.
IMPORTANT: KNOWLEDGE OF YACC or BISON or ANTLR ARE REQUIRED. Without them you couldn't complete this task IMPORTANT: this is a strict algorithmic task, you will have to do a lot of math here Problem: - There is C code, generated by alex (scheme.h + scheme.c), which has all transition tables, states, matches and backup rules; - There is no original file; - There are 25 such cases: scheme1.h + scheme1.c, scheme2.h + scheme2.c, …, scheme25.h + scheme25.c - All original files are lost; Goal: - Write a tool, which will take existed scheme1.h + scheme1.c and generates for it. - Only lex restoration is needed, ayacc files are ok All info is here

Hello, On this deliverable what you have to deliver is the grammar of a claculator More specifically, I will give you an example which contains the an example grammar. You need to state what are the rules that the verbal and syntactic analyst obey? You have to give such a file as the first deliverable, and in essence explain the rules that your grammar follows in a document " I will be happy to give a good review and 5/5 stars if you deliver completely, correctly and in time. Also I will be happy to have more projects of this kind with you. Thank you
Need an ANTLR and node (typescript) based Lexer Parser which can take a file as input and generate a React typescript based node SPA from it. This app will be deployed as a docker compose file. Once this is executed it will allow generating xx files. Steps to be done for testing success 1. fetch solution from github 2. create xx file in input directory 3. run "docker-compose up" 4. copy url shown in terminal window 5. open url in browser 6. drag/drop components on one or more forms 7. export xx file 8. the file should be created in output folder 9. shut down all environments 10 clear input folder and copy generated xx file from output to input folder 11. repeat 1 to 10 for remaining use cases. The project will be successful if the app generated from the too...

we are creating a DSL, a dedicated query language for our web scraper. It is preferable to use ANTLR of which we already have a grammar to validate but we are open to the use of other tools. The important thing is the result. The parser will have to integrate spark to build its acquisition data pipeline but we'll see it together. An NDA will have to be signed

A Freelancer is needed to write a lexical analyzer that will tokenize Visual Basic 6.0 grammar. This utility should be written in C++, using tools such as ANTLR or FLEX. The output is written to a file. Please bid what you feel is appropriate.

I have written a working antlr4 parser and need an expert to finish the processing of the parse tree. I need help in transforming it into a simplified abstract parse tree. The requirements of the output data structure: - can be serialized to json later on - reflects the ANTLR parse tree a 100%, also in order of appearance of the nodes - I plan to build sql queries based on the data structure later on, please come up with a design that is easily navigatable through a nested key:value like structure for example - there are intermediary nodes in the parse tree that do not contain any useful information. These nodes shall be skippable (configurable), so they don't appear in the final (simplified) abstract parse tree. Important: final/terminal values can be located below of one or ...

...+ (1 * d + 0)" will output an optimized form of that expression like a: "a * (b + c) + d" etc. Other examples at the bottom. Parser's operators should be: * - logical conjunction (AND) + - logical alternative (OR) ~ - logical negation (NOT) (...) - expression grouping a,b,c,d - some variable (VAR) 0, 1 - Boolean true or false (BOOL) The parser needs to be written in python PLY generator or ANTLR in any language. Best would be to apply the Quine-McCluskey algorithm implementation () or/and Karnough tables.

Build a file,write a Java source code for the visitor (or listener) class and a Java source code for your main class. Develop a language app that is able to interpret source code in a language whose old dialect looks like Python and newer dialect looks like Java. More specifically, the app must use a single grammar and must be able to interpret (and execute) the attached input files. One file is written in a Java-like language and the other is written in a Python-like language.
Need a grammar that switches between 2 languages , when compiling the .java file it must be able to recognize if the input file provided at the run time is correct for the language on which we are invoking. i.e while entering the executable java after javac success, u need to mention the language and the input file as CMD arguments, based on the 1st argument, a decision will be made as to which part of the garmmar needs to be executed i.e language 1 or 2 , then checks if the input file is written in that particular language and if it is in that language execute the file or else throw an error. Error must be thrown at the 1st encounter of different language. For instance the input1 file and input 2 file for language 1 and language 2 respectively, the variable declarations syntax may be sam...
cite your sources and clearly display borrowed text and give credit to its author(s). Write a one-to-two-page synopsis (Times New Roman, 12pt font, 1'' margin all around, single or 1.5 spaced) of the two tools that are presented in the thesis (Comment Search and Code Search). Your narrative must be coherent and must describe (1) how language recognizers helped with the search and (2) how the output from each of these tools was used to draw conclusions about the source code under review. ->What is the thesis' main problem statement? How relevant is the problem statement to the activity of language recognition (i.e., why would we need a parser generator to solve the problem statement)? -> For each tool, include a reference, to a location within Klein's thesis wher...

I need someone to please create 3 ANTLR grammars to interchangeably convert between a TXT file, SQL file or a JSON file. Formats are attached. Acceptance Criteria: 1. On passing the text file to script it should output SQL and JSON files. The SQL format should be able to execute on a MySQL db to successfully create a DB and the generated JSON should be validated on W3C validator. 2. Passing SQL output from step 1 to the script, it should be able to recreate the TXT file exactly similar to the original and a JSON file exactly same as the one from Step1 3. On Passing JSON output from step 1 to the script, it should be able to recreate the TXT file as the original was and a SQL file exactly same as the one from Step1 If the above 3 criteria are met for a set of 3 test...

I need help with a Java project. It's building an interpreter. I can't use ANTLR. I need to build a new language that has a lot of restrictions. Just a very bare bones language.
We use ...definition document giving the definition in extended Backus-Naur form (EBNF) as defined in ISO14977. We can supply detailed documents describing the format, skeleton parsing programs from the 1980s for illustration, and many sample "known good" data files. It seems sensible to have an Antlr v4 parser to read the legacy file and produce a program (in Java perhaps) that will write the data into an XML file. So this project needs someone familiar with Antlr to write one for us. The final deliverable would be that Antlr parser, following all the EBNF definition of the legacy file format. We are happy to send the definition documents so that you can assess the size of this task before you commit to it. We are not under strong time constraints - this cou...

Hello guys, I have created a language on Antlr with Java. I want these fixes: 1. create an executable of the language 2. add loops and change my example so they have loop 3. add some data structure like list array or set 4. Review/create and improve my report, presentation and text files I want it bug free and easy to use. Everything needed is described fully on the ATTACHMENT DOC (3 pages). I also attach my Creation. My budget is max 100 usd as most part is complete. I just want to be fully completed. Thank you a lot for your understanding
