I am currently using ANTLRWorks 2. I don't know how to interpret example in it. In ANTLRWorks-1.5.2 there is an interpreter tab that you can paste your example. Is there something like that in ANTLRWorks 2? How you can get parse tree for input? Does input have to be in a specific file?
BTW, I couldn't get any result by using Run->Run in TestRig and uploading any input file.
How you can get parse tree for input?
The way you already tried: Run → Run in TestRig
Does input have to be in a specific file?
Yes.
BTW, I couldn't get any result by using Run->Run in TestRig and uploading any input file.
Then you probably did something wrong. Incorrect input file? Incorrect start rule? Pretty hard to say, really.
There's also the ANTLR4 plugin for IntelliJ which does interpreting on the fly and produces the parse tree. Also a very nice tool!

How to parse a OFX (Version 1.0.2) file in PHP?
I am not a developer. What easy tool can I use to make this code run with no code skill or appetence ? web browser is pretty hard to use for non dev guys.
I need this to use the file into Power BI, which accept M code, json source or xml, but not sgml ofx or PHP.
Thanks in advance
Welcome Didier to StackOverflow!
I'm going to try and give you a clue how I'd approach the problem here. But keep in mind that your question really lacks details for us to help you, and I'm asking to update your question with example data that you want to integrate into PowerBI. Also, I'm not too familiar with PowerBI nor PHP, and won't go into making that PHP code you linked run for you.
Rather, I'd suggest to convert your OFX file into XML, and then use PowerBI's XML import on that converted file.
From your linked question, I get that your OFX file is in SGML format. There's a program specifically designed to convert SGML into XML (which is just a restricted form of SGML) called osx. I've detailed how to install it on Linux and Mac OS in another question related to SGML-to-XML down-converting; if you're on Windows, you may have luck by just downloading a really ancient (32bit) version of it from ftp://ftp.jclark.com/pub/sp/win32/sp1_3_4.zip. Alternatively, you can use my sgmljs.net software as explained in Converting HTML to XML though that tutorial is really about the much more complex task of converting HTML to XML/XHTML and will probably confuse you.
Anyway, if you manage to install osx, running it on your OFX file (which I assume to have the name yourfile.ofx just for illustration) is just a matter of invoking (on the Windows or Linux/Mac OS command line):
osx yourfile.ofx > yourfile.xml
to result in yourfile.xml which you can attempt to load with PowerBI.
Chances are your OFX file has additional text at the beginning (lines like XYZ:0001 that come before <ofx>). In that case, you can just remove those lines using a text editor before invoking osx on it. Maybe you also need a .dtd file or additional instructions at the top of the OFX file informing SGML about the grammar of your file; it's really difficult to say without seeing actual test data.
Before bothering with SGML and all that, however, I suggest to remove those first few lines in your OFX file (everything until the first < character) and check if PowerBI can already recognize your changed input file as XML (which, from other OFX example files, has a good chance of succeeding). Be sure to work on a copy of your original file rather than overwriting it. Then come back and update your question with your results and example data.
Let's say I have a source code file. I want to give this file to the ANTLR and generate the same code and save it to an output file.
Usage:
To beautify the input file.
To add some comments to the input file.
To inject some code into the input file.
Is it possible to do such a thing by exploiting ANTLR?
Basically, I am trying to do a source-to-source transformation with ANTLR from C/C++ to C/C++.
I am interested to add, delete, replace, or modify some lines of the code and generate an output that complies with C/C++ language rules.
P.S.: Please let me know if you know any other tool (other than CLANG) that does the same thing. Parsing C/C++ (or even Fortran) and providing some events to the user and let the user modify the source code.
OK, it may sound fairly straightforward but I'm still not sure how to go about it.
I know it's possible to check file type based on file extensions, using UTIs (e.g. Get the type of a file in Cocoa).
However, I need to be able to get the file type (in more general terms, like "text", "image", "else"), depending on the content.
Is that possible?
Any ideas?
One route forward is to call the file command and parse its output, but that is fairly horrible, and I wouldn't do that as it's slow and you are susceptible to changes in the output.
The file command uses a pretty extensive database of byte patterns to test the contents of the file and I would be tempted to implement my own internal version of it, or use this library (which I think might need some work before it works under OSX).
I need a parser (mainly for the "select" type of queries) and avoid the hassle of doing it from scratch. Does anybody know how to use the scan.l/gram.y of pgsql for this purpose? I've looked up pgpool too, but it seems similar. Currently, it might be very helpful if someone could give instructions to compile the parser (using the makefile provided maybe) without errors so that it can be supplied (valid?) queries and outputs the parse tree (in whatever form)!
You probably cannot take any file from postgres source tarball and compile it separately. Parser use internal OOP structures (implemented in C). But there is some possibility (not simple) - ecpg preprocessor try to transform PostgreSQL gram file to secondary gram file - and you can use same mechanism. It use a small utility parse.pl (it is part of PostgreSQL source code (src/postgresql/src/interfaces/ecpg/preproc))
PostgreSQL compiles the language parser using yacc. Presumably you could take the yacc files and create a compatible parser with very little effort. Note you must have flex and yacc installed to do this.
Note this is not taking a .c file from source and transplanting it into your system. All you are getting is the parser, not the planner or anything else.
Given the level of detail in the question no more detail can be possible. Perhaps you could start there and post another question when you get stuck.
I'm trying to integrate custom dynamic analysis tools to CDash. Such as KWStyle, CppCheck and Visual Leak Detector.
I'v figured out that I need to generate a DynamicAnalysis.xml file and submit it to CDash, from CTest scripts.
I think I know how to run the external tool as a part of the ctest script.
Either by using these variables to change how ctest_memcheck() works
CTEST_MEMORYCHECK_COMMAND
CTEST_MEMORYCHECK_SUPPRESSIONS_FILE
CTEST_MEMORYCHECK_COMMAND_OPTIONS
or by running the tool from the execute_process() command.
But I'm a bit uncertain which one to use.
The main problem I think I have is, how can I extract errors from the output of the custom tool and include that information into the DynamicAnalysis.xml to submit?
The extreme solution i see is that i'd need to make a program that generates a valid DynamicAnalysis.xml file.
But the problem is that I don't know the syntax of the DefectList element in the XML file. I have found no answer from google and even the XML Schema for that file is unhelpful.
EDIT:
Looking at this:
http://www.cdash.org/CDash/viewDynamicAnalysis.php?buildid=987149
What draws my attention are the labels, especially the empty ones. I don't see how these would come from the DynamicAnalysis.xml file. Maybe it tracks any labels that have ever appearred? Can i create my own custom labels somehow?
Does CDash create the labels automatically, depending on the tool type? Does this block custom defect types?
I'm just guessing here, so the question is; can i create custom labels for my custom tool, just by generating a DynamicAnalysis.xml - file.
It occurred to me that the amount of different errors from CppCheck (static code analysis) is huge, compared to valgrind for instance. I'm not that certain that I should use the dynamic analysis. Maybe a custom build type (Continuous / Experimental / Nightly) thing would work better. Like this:
http://www.cdash.org/CDash/buildSummary.php?buildid=930174
I have no idea how to do this, i guess it requires meddling around with CDash code?
Which one would work better?
If you are using valgrind, you can simply set CTEST_MEMORYCHECK_COMMAND to the full path to valgrind, and ctest will generate the DynamicAnalysis.xml file for you from the valgrind output when you call ctest_memcheck.
The best way to understand the possible values that can appear in the DynamicAnalysis.xml file is to analyze the source code of CTest.
The file CMake/Source/CTest/cmCTestMemCheckHandler.cxx has the list of defect types in a variable named "cmCTestMemCheckResultLongStrings". Search through that file for references to that variable to see what the possible values are and how they are used to generate "<Defect/>" xml elements.
EDIT (for additional information):
You can also easily see what XML elements CDash is expecting by inspecting its source code. Specifically, the file "CDash/xml_handlers/dynamic_analysis_handler.php".
From what I'v learned so far, is that for a tool that runs on the tests made in the cmake script, the Dynamic Analysis is the thing.
For tools that run on the entire program, a custom Build.xml is the thing you need.
I found out that i can commit those files from the ctest_submit command by using the FILES parameter.
I also found out that you can add custom "build names" to the side of Continuous, Nightly, and others.
And that you can set the builds from certain machines to be automatically transferred under these.
The custom labels under DynamicAnalysis did come from somewhere in CDash, i can't remember where anymore.
