• Parser generator for JavaME

  - by Anders K.

  First: I have looked at this SO question but unfortunately there is no mention of JavaME I am looking for a parser/lexer generator that produces code that can run on the Blackberry and its (obnoxious) JavaME. E.g. at first I thought I could use ANTLR however it seems the run-time library is not compatible with JavaME TIA

• Generalized Bottom up Parser Combinators in Haskell

  - by Panini Sai

  I am wondered why there is no generalized parser combinators for Bottom-up parsing in Haskell like a Parsec combinators for top down parsing. ( I could find some research work went during 2004 but nothing after https://haskell-functional-parsing.googlecode.com/files/Ljunglof-2002a.pdf http://www.di.ubi.pt/~jpf/Site/Publications_files/technicalReport.pdf ) Is there any specific reason for not achieving it?

• C++ code parser/processor library

  - by uray

  is there any library that parse a source code of C++ to produce lets say, call graph, class inheritance tree, flow control, class member list or anything as a ready to use graph or structure in code (not in diagram image). to make it more clear, suppose to generate call graph image, there will be a process like this: ` C++ source -> parser -> intermediate structure -> renderer -> call graph image ^ | [i need this] `

• What is the fastest XML parser in PHP?

  - by Jakub Lédl

  Hi, for a certain project, I need some way to parse XML and get data from it. So I wonder, which one of built-in parsers is the fastest? Also, it would be nice of the parser could accept a XML string as input - I have my own implementation of thread-safe working with files and I don't want some nasty non-thread-safe libraries to make my efforts useless.

• Natural Language date and time parser for java

  - by Pranav

  Hey guys, I am working on a Natural Language parser which examines a sentence in english and extracts some information like name, date etc. for example: "Lets meet next tuesday at 5 PM at the beach." So the output will be something like : "Lets meet 15/09/2009 at 1700 hr at the beach" So basically, what i want to know is that is there any framework or library available for JAVA to do these kind of operations like parsing dates from a sentence and give a output with some specified format. Regards, Pranav

• How lookaheads are propagated in "channel" method of building LALR parser?

  - by greenoldman

  The method is described in Dragon Book, however I read about it in ""Parsing Techniques" by D.Grune and C.J.H.Jacobs". I start from my understanding of building channels for NFA: channels are built once, they are like water channels with current you "drop" lookahead symbols in right places (sources) of the channel, and they propagate with "current" when symbol propagates, there are no barriers (the only sufficient things for propagation are presence of channel and direction/current); i.e. lookahead cannot just die out of the blue Is that right? If I am correct, then eof lookahead should be present in all states, because the source of it is the start production, and all other production states are reachable from start state. How the DFA is made out of this NFA is not perfectly clear for me -- the authors of the mentioned book write about preserving channels, but I see no purpose, if you propagated lookaheads. If the channels have to be preserved, are they cut off from the source if the DFA state does not include source NFA state? I assume no -- the channels still runs between DFA states, not only within given DFA state. In the effect eof should still be present in all items in all states. But when you take a look at DFA presented in book (pdf is from errata): DFA for LALR (fig. 9.34 in the book, p.301) you will see there are items without eof in lookahead. The grammar for this DFA is: S -> E E -> E - T E -> T T -> ( E ) T -> n So how it was computed, when eof was dropped, and on what condition? Update It is textual pdf, so two interesting states (in DFA; # is eof): State 1: S--- >•E[#] E--- >•E-T[#-] E--- >•T[#-] T--- >•n[#-] T--- >•(E)[#-] State 6: T--- >(•E)[#-)] E--- >•E-T[-)] E--- >•T[-)] T--- >•n[-)] T--- >•(E)[-)] Arc from 1 to 6 is labeled (.

• Doxygen C++ comment string parser in python?

  - by Sebastian

  Does anybody know of a python module to parse a doxygen style C++ comment string? I mean a string like this (simple example): /** * A constructor. * A more elaborate description of the constructor. * @param param1 test1 * @param param2 test2 */ and I would like to extract the brief, the long description, the parameters, the return value etc. I'm currently doing this using string methods and regular expressions but my solution is not very robust. Alternatively does anybody know an easy to use parser lib that I can set up quickly? Thanks in advance

• Are there any PHP DocBlock parser tools available?

  - by Beau Simensen

  I would like to build some smaller scale but hightly customized documentation sites for a few projects. PhpDocumentor is pretty great but it is very heavy. I thought about trying to tweak the templates for that but after spending only a couple of minutes looking into it I decided that it would be too much work. Ideally I'd like to see something to which I could pass a bunch of files and have it return all of the files, classes and properties and methods, along with their meta data, so that I could build out some simple templates based on the data. Are there any DocBlock parser-only projects that will help me in this task, or am I stuck reinventing that wheel?

• asn.1 parser in C/Python

  - by elventear

  I am looking for a solution to parse asn.1 spec files and generate a decoder from those. Ideally I would like to work with Python modules, but if nothing is available I would use C/C++ libraries and interface them with Python with the plethora of solutions out there. In the past I have been using pyasn1 and building everything by hand but that has become too unwieldly. I have also looked superficially to libtasn1 and asn1c. The first one had problems parsing even the simplest of files. The second has a good parser but generating C code for decoding seems too complex; the solution worked well with straightforward specs but choked on complex ones. Any other good alternatives I may have overlooked?

• dojo parser not escaping quotation marks in attributes?

  - by peirix

  Whenever I'm using quotation marks inside an attribute value in dojo, it seems dojo's parser isn't handling it very well... <textarea name="content.locale['en']" dojoType="dijit.form.SimpleTextarea"> </textarea> Turns into: <textarea ]="" en="" name="content.locale["></textarea> With the surrounding <div>s and what not is added by the dijit widget. Any ideas? EDIT Seems this is working as it should with other elements, it's just the SimpleTextarea that's causing a problem..

• Delphi JavaDoc Parser

  - by Christian Sciberras

  I need to parse JavaDoc (documentation) comment syntax with Delphi 7. It is well known in the java world as "JavaDoc", but I'm actually doing this for PHP, ie, parsing JavaDoc in some PHP code. Call it PHPDoc if you want to. To see how these comments work, you can see RAD IDEs like NetBeans etc. Example of JavaDoc for addition function: /** * Adds to numbers together. * @param integer $a The first number. * @param integer $b The second number. * @return integer The resulting number. */ function add($a,$b){ return $a+$b; } Please note that the parser need not be full, ie, parsing all of the PHP code. I mean, it's perfectly fine if it accepted the comment text only as input. Cheers, Chris.

• Expression parser library for Android.

  - by Malx

  What is the best way to evaluate simple conditional statements like: "a>b" ? "x-4<10+y & y>x" ? Expressions are loaded from external file. Variables are set in application. Syntax used is not essential. It may be "&" or "and" or any other supported with language/library. I need to take different action depending on result of evaluation - is it true or false. Could I use any parser already included with Andorid? Is there some way to use JS "eval" from browser component? Is it possible to use sqlite expressions to get true/false result without selecting anything? Those libraries are implemented in native code. Will it be faster and less battery expensive?

• JSP compilation error upon changing XML parser to Xerces

  - by elduff

  All, I'm working on a java webapp that we deploy in the Resin web app server. I have been doing some XML parsing for a new part of the application, and realized that our app was using Resin classes to do the parsing. I wanted to get away from that and use something more standard for a number of reasons, so I set these system properties in my resin config file (and added the xerces jar to my classpath): <system-property javax.xml.parsers.DocumentBuilderFactory="org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"/> <system-property javax.xml.parsers.SAXParserFactory="org.apache.xerces.jaxp.SAXParserFactoryImpl"/> And, now I'm getting JSP compilation errors on several pages (I guess Resin's built in parser was more lenient). The error reads: org.xml.sax.SAXParseException: The value of attribute "title" associated with an element type "display:column" must not contain the '<' character. And, the 'display:column' tag on some pages does indeed contain markup in the 'title' attribute. Here's an example: <display:column scope='col' class=" appealColorBG selectAllWidth" title="<span class='centerThis'><label for='selectAll'>Select All</label><br /> <input type='checkbox' name='selectAll' id='selectAll' onClick='selectAllCheckboxes();'/></span> " > That's some ugly JSP code, I know, but it's also code that's already in production, so I'm hesitant to change it. Does anyone know of a way that I can set xerces so that it will allow the JSP to compile as is?

• CSS Parser - Insert mtimes

  - by brad

  What command line tool can I use to automatically insert mtimes into urls in my css files for the purposes of breaking the cache? /* before */ .example { background: url(example.jpg); } /* after */ .example { background: url(example.jpg?1271298451); } Also, I would like this tool to spit out the latest mtime as the css files mtime. (If the css file is still cached then the new urls will not get to the client.) In searching the web, I have found very few tools that can do this. I am even considering rolling my own, but have found very little in the way of css parsers that are actively maintained. A candidate should be: fast (I don't want to wait 30 seconds on deployment) command line accessible (something like "cat foo.css bar.css | cssmtime out.css") What I've found so Far yui compressor - initially I thought I would extend the yui compressor to do this, but found that it is implemented as a bunch of regex's and not a parser. csstidy - last release was in 2007 and development has been suspended, but does have an option for inserting mtimes (also written in php, something I have no experience in) cssutils - python sac implementation - seems to be actively maintained, but also seems like overkill for my needs. Also, written in python which I have experience with csspool - ruby sac implementation - I don't know much ruby, but would like to learn other sac implementations - There are several java implementations, and a c implementation neither of which I know much about What's your experience? Have you used any of these libraries? Was the experience positive? Would you recommend I go with them for my purposes?

• General Address Parser for Freeform Text

  - by Daemonic

  We have a program that displays map data (think Google Maps, but with much more interactivity and custom layers for our clients). We allow navigation via a set of combo boxes that prefill certain fields with a bunch of data (ie: Country: Canada, the Province field is filled in. Select Ontario, and a list of Counties/Regions is filled in. Select a county/region, and a city is filled in, etc...). While this guarantees accurate addresses, it's a pain for the users if they don't know where a street address or a city are located (ie, which county/region is kitchener in?). So we are looking at trying to do an address parser with a freeform text field. The user could enter something like this (similar to Google Maps, Bing Maps, etc...): 22 Main St, Kitchener, On And we could compartmentalize it into sections and do lookups on the data and get to the point they are looking for (or suggest alternatives). The problem with this is that how do we properly compartmentalize information? How do we break up the sections and find possible matches? I'm guessing we wouldn't be guaranteed that the user would enter data in a format we always expected (obviously). A follow up to this would be how to present the data if we don't find an exact match (or find multiple exact matches... two cities with the same street name in different counties, for example). We have a ton of data available in the mapping data (mapinfo tab format mostly). So we can do quick scans of street names, cities, states, etc. But I'm not sure about the best way to go about approaching this problem. Sure, using Google Maps would be nice, bue most of our clients are in closed in networks where outside access is not usually allowed and most aren't willing to rely on google maps (since it doesn't contain as much information as they need, such as custom map layers). They could, obviously, go to google and get the proper location then move to our software, but this would time consuming and speed of the process can be quite important.
