antlr - Can Xtext be used for parsing general purpose programming languages? -

-

i'm developing general-purpose agent-based programming language (its syntaxt inspired java, , using object in language).

since beginning of project doubtful fact of using antlr or xtext. @ time found out xtext implementing subset of feature of antlr. decided use anltr our language losing possibility have full-fledged eclipse editor free our language (such nice features provided xtext).

however, best of knowledge, summer xtext project has done big step forward. quoting link:

what limitations of xtext?

sven: can implement kind of programming language or dsl xtext. there 1 exception, if need use called 'semantic predicates' rather complicated thing don't think worth being explained here. few languages need concept. prominent example c/c++. want topic next release.

and reinforced in xtext documentation:

what xtext? no matter if want create small textual domain-specific language (dsl) or want implement full-blown general purpose programming language. xtext can create own languages in snap. if have existing language lacks decent tool support, can use xtext create sophisticated eclipse-based development environment providing editing experience known modern java ides in surprisingly short amount of time. call xtext language development framework.

if xtext has got rid of past limitations why still not possible find complex xtext grammar best known programming languages (java, c#, etc.)?

on antlr website can find tons of such grammar examples, concerns xtext instead sample able find 1 reported in documentation. maybe xtext still not mature used implementing general purpose programming language? i'm bit worried this... not start re-write grammar in xtext recognize not suited that.

i think nobody implemented java or c++ because lot of work (even xtext) , existing tools , compilers excellent. however, have @ xbase , xtend, expression language ship xtext. built xtext , quite proof can build xtext. have done in 4 person months.

i did couple of screencasts on xtend:

note, can embed xbase expressions language.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
