  • What grammar based parser-generator tools exist for ruby?

    - by cartoonfox
    What open source (preferably gem-based) parser-generator options do I have in Ruby? I've used (flex&bison)|(lex&yacc) from C in the past, and I'm comfortable with BNF-style specifications. I've heard of treetop, but it looks a bit alien and verbose compared to yacc... Purpose: I want to convert my text markup language to a BNF and generate the parsing code. I think it's a better strategy than my first-order solution: http://github.com/dafydd/semantictext/blob/master/lib/semantictext/rich_text_parser.rb

  • Const unsigned char* to char8

    - by BSchlinker
    So, I have two types at the moment: const unsigned char* unencrypted_data_char; string unencrypted_data; I'm attempting to perform a simple conversion of data from one to the other (string - const unsigned char*) As a result, I have the following: strcpy((unencrypted_data_char),(unencrypted_data.c_str())); However, I'm receiving the error: error C2664: 'strcpy' : cannot convert parameter 1 from 'const unsigned char *' to 'char *' Any advise? I thought using reinterpret_cast would help, but it doesn't seem to make a difference.

    - by mon4goos
    If you call NSRunAlertPanel() from a background process in Cocoa, the dialogue does not come to the front and instead stays behind other windows. This post shows that you can bring the dialogue to the front if you convert the process to a foreground process. If you keep the process a background process, however, is there any way to achieve this behavior?

  • How can I get System.Type from "System.Drawing.Color" string

    - by jonny
    I have an xml stored property of some control <Prop Name="ForeColor" Type="System.Drawing.Color" Value="-16777216" /> I want to convert it back as others System.Type type = System.Type.GetType(propertyTypeString); object propertyObj = TypeDescriptor.GetConverter(type).ConvertFromString(propertyValueString); System.Type.GetType("System.Drawing.Color") returns null. The question is how one can correctly get color type from string (it will be better not to do a special case just for Color properties) Update from time to time this xml will be edited by hand

    Id like to convert it to uppercase for the simple purpose of formatting so it will adhere to a future case statement. As I thought case statements are case sensitive. I see all over the place the tr command used in concert with echo commands to give you immediate results such as: echo "Enter in Location (i.e. SDD-134)" read answer (user enters "cfg" echo $answer | tr '[:lower:]' '[:upper:]' which produced cfg # first echo not upper? echo $answer #echo it again and it is now upper...

  • How to raise a validation event from a key press

    - by flavour404
    Hi, I want to raise the: private void txtbox_startdate_Validating(object sender, System.ComponentModel.CancelEventArgs e) {} Function from a key leave event. The leave event looks like: private void txtbox_startdate_Leave(object sender, EventArgs e) {} The trouble is of course if I try and call it in this manner: txtbox_startdate_Validating(sender, e) An error is raised because in this case 'e' is an EventArgs whereas the validation function wants a System.ComponentModel.CancelEventArgs and so, how do I convert EventArgs to a System.ComponentModel.CancelEventArgs or create one so that I can call my validation function? Thanks, R.
