Extract grammar definition from ANTLR g file -


i have rather complex antlr grammar lot of custom handling code (which among other things used creation of internal data structures , handling of data in general). i'd know if antlr provides capability (or if there existing tool) removing custom grammar handling (e.g. java code, @init, @after sections, parameters, return types, etc) , leave me barebones grammar definition. know regex handling, imagined recurring task there may out there this.

example:

rule[string blabla] returns [blabla] scope{    blablabal; } @init{    blalbabla; } :    string comma string {blablabla code blablabla;} ;

would return

rule:    string comma string ;

have tried -print option? (v3 far)

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
