great, because that's exactly what i was going to ask you, johnathon :) [in the meantime - much as i hate asking, could you kindly email me a copy, to...
Well, lucky for me, I'm not ashamed of my sneakers OR my darth vader helmet! I quite see your point and your plight then. I don't actually think that you can...
Hello! Please help me. I write Pascal language parser. In this situation while do write(1) I print the following error: "Identifier expected" I want to print...
Vladimir, et al: I am now seeing a different manifestation of the "difference" problem between the builder environment and our running program. The problem in...
Geo, This sounds very strange. It looks like a problem with lexical scanner. Could you give me a small grammar sample where you define the string and which can...
Yes, whilst parsing I would like to collect a group of tokens For instance (Name Contains ericsson) And (DS Mnemonic Contains F) Token group 1 = Name Contains...
That is quite strange. If the error being reported as a syntax error or a lexical error? Also, is the grammar line-based? - Devin ...

For your final precedence level, you can accept a series of identifiers. Your program will have to semantically give the first and last identifiers the status...

Hey everyone, I just uploaded version 3.4.3 of the GOLD Builder. The most recent version fixes a very minor (yet annoying) bug as well as adding a brand new...
Vlad: Thanks for responding. Here is the relevant part of the grammar. String literals are the things getting errors. As I said, the Builder environment...
Devin, thanks for the responding. The grammar IS line-based, based on the VB one found on your site, but heavily edited down. It is a parser error when...
Geo, First of all, thank you very much for reporting this bug. The bug was in transition vector code used for small number of states and if you have Unicode...
Vladimir, Whilst you're updating your excellent C# implementation, I had a problem a while back with the private m_lrStack running out of space. I fixed it by...
I may have seen this. Is the symptom an out of range exception? I am getting in on a very large Select-Case statement (maybe 80+ cases). --Geo ... problem a ...
I have uploaded new version of the engine to http://notebar.com/GoldParserEngine.html It contains the m_lrStack fix provided by Nathan and the fix for the ...
Dear all, I have a project in which I want to make a compiler that don't compile the code but only generates the equivalent quadruples of the code, can I do...
Yes. This classification of parser is known as a "translator". Basically, after the system parses the text, it converts the text into another language. This ...

I've been thinking, a scary proposition I know, about how one might develop a test plan to ensure coverage on a particular grammar. Does anyone have a ...
That's an interesting issue. I don't think there is any formal methodology for creating test cases. I could create a simple algorithm that would look through...

... The question is what one wants to test. If L is the intended language, G the GOLD-grammar defined for L, M the parser generated by GOLD from G: - L=L(G) ? ...
In my work with converting VBScripts to .net languages, I simply got my hands on as many scripts as I could (~5000) and wrote a little program to batch parse...
Hi All, I am currently trying to create a parser for a scripting language. The purpose is to simply verify that the entire script is correct in terms of...
A token isn't a symbol, which is what I think you are confusing. A Symbol can be either a lexeme or a production, whereas a token has a symbol, a string...
Well, that Ncover certainly is a start... I suppose I don't want to test every possible lexical combination, but just every production a with each type of...
... I also sometimes like to test specific productions that I *don't* want to parse. Sometimes there are specific patterns that you don't wish to support and...
... Would you please give an example. A solution would require GOLD to be enabled to check whether subgrammars G' have the dcfl property. Furthermore GOLD...
... Unfortunately any specific examples I might have are on a different machine and/or lost. IIRC, the biggest grammar that I did anything near "extensive"...
Hi I have been thrown in at the deep end.. We have an application that contains the Marcus Klimstra C# translation of the GOLD engine. I have modified and...
I'm getting an lexical error for the following expression expression = [ ~'!#-Z_a-zŁ]{0,65} Is there special formatting that Gold requires for regex?...
