Programming :: Implement The OOP In Interpreter?
Mar 7, 2011I have a partially completed interpreter that has first-calss functions and can store scopes in variables. That way it is possible to implement a simple class like this:
Code:
MyClass = func () {
value = 0;
setValue = func (x) value = x;;
[code]....
But what about inheritance, and what if I want to know the type of the object?
Programming :: BASH Scripting: Hide Plain Text Passwords
Jun 15, 2010I was wondering if there is way to hide passwords in bash scripts. For example: I have to write a script to export a full ldap structure, and I'm using the ldapsearch -y passwordfile, where password file is a plain text file that contains the password. Is there a way to hide the password from that file?
I was thinking to remove the r attribute from the file and before the script is lunched to put the attribute back, but is not a good solution, the same with immutable attribute.

View 3 Replies View RelatedProgramming :: Implement Two Periodical Processes In C++?
Jul 28, 2010I am doing real time programming in C++, under Linux. I have two processes, let me say A and B. A process is being started periodically, every 5ms. B process is being started every 10ms. The process A is doing data processing. The process B is reading that data and displays it. I am confused about how to run periodically processes. The problem is that the period of process A should be as much as it is possible accurate (5ms). For the process B it isn't so important. I have created independent processes, each in one .cpp file, and I am starting them from bash file. Is that OK? I don't have to make child processes in order to have parallel processes?
View 1 Replies View RelatedProgramming :: How To Implement Whole New Writing System
Aug 11, 2010So basically, there is a really cool writing system I have been working on. It could be viewed (for simplification purposes) like an encryption method for the Latin script.
Facts about the writing system:
It has a little over 300 symbols.
It is syllable-driven.
It is highly compositional (eg. "c", "ca", "cae", "ca " and "ci." all map to different symbols - and NOT by overlaying elements)
Symbols have medium graphical complexity (comparable to Korean Hangul, or Japanese Hiragana)
Has a rather complex set of diacritics (~10, some of which can go on any symbol)
Has no ligatures
How transliteration occurs:
Sequences of Latin symbols map to certain symbols. Example below:[G][rou][p ][hu][g.]Characters sequences between "[" and "]" map to a single symbol (so it would take only 5 symbols to write "Group hug.").
How I want it to work:
I would like to have a daemon that: Intercepts all text displayed on the screen.
Converts it to my writing system (changes letter sequences with individual Unicode codes)
Leaves unsupported symbols unchanged.
Displays all the text on the screen using my font and characters intertwined with the fonts and characters left unchanged.
For example, if you take the following line of C++ code:for (i = 1; i <= n; i++)
I would like it displayed like this:[fo][r ]([i ]= [1]; [i ]<= [n]; [i]++)
Bold-symbols should be in my Unicode font with special symbols defined for this writing system, and the rest should be in its original font and encoding. Also, I would like this encoding to hold for display-purposes only. The data in the memory should remain unaffected. This also means real-time adjustments: if I open a text editor (say, from the OpenOffice Suite) and I start typing, I would like to see what I type encoded with my writing system, even though the document actually contains Latin letters. This also means that the symbol immediately before the cursor may change as you type.

Programming :: Implement Own Protocol With AgenjJ?
Feb 9, 2011I developed a protocol "it's a modification of OLSR" for wireless networks, it was with JAVA and I try to simulate it on NS2, I used AgentJ, so in the TCL I did any thing like usual;
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop)Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
[code]....
and I didn't specified the protocol because I attached my nodes to the JAVA class responsible for the protocol, but when I run it generates errors, it claims the protocol to use, so I don't know how proceeding.

View 2 Replies View RelatedProgramming :: Implement Variable Substitution In Strings?
May 6, 2011I have an interpteter that supports string literals, and the way it works is that the lexer returns the entire string as a single token, with the quotes removed and escape sequences replaced with the literal characters they represent.
I already implemented single-quote strings, they don't interpret any characters specially except for the single quote. I partially implemented double-quoted strings, they already support all the same backslash escape sequences that C does. But I would also want to add variable substitution.
The way it would work is that "${expression}" would interpret the expression (which could just be a variable name) and replace itself with the result. But I have no idea how to do this.
In case it matters, I'm using a hand-written lexer and recursive-descent parser.
Programming :: Implement SAML 1.1 SSO Process In Php / Java Or C#?
Oct 11, 2010I need to implement SAML 1.1 SSO process in Php(Preferred), Java, or C# I am having a very difficult time finding information related to this task. If I could use SAML 2.0 I would be home free with "Simple Saml Php" but I am not that lucky. Would the process be as simple as building the SAML in XML then submitting it with a SoapClient? According to the Docs I've read that would appear to work.

Jul 2, 2010I'd like to implement a dynamic menu which will allow me to specify an IP address and read it into memory. This is what I've got so far (it's fairly basic...)
Code:
IPS=`ifconfig -a | grep 'inet addr:' | awk '{print $2}' | tr -d "addr:"`
PS3='Select an option and press Enter: '
select i in $IPS
do
case $i in
$i) echo $IPS;;
esac
done
echo $IPS
At the moment it just says "Which IP would you like to use" and then freezes, most success I've had is it showing all the IP's listed in ifconfig and then showing the same menu.

View 2 Replies View RelatedProgramming :: Implement User Ranking In Php With A Huge Number Of Users?
Aug 21, 2010I'm writing a user ranking module for a site. This ranking depends on some criterias and it's possible to set or unset any one of these criterias in order to consider them in calculating the user rank or not. And here's the way I've implemented the ranking calculation :
when I set one or more of the criterias to be considered in ranking , for each user in the system I insert one record for each criteria , for example : if I have 2 criterias and both are set and consider that I have two users , I'll have :
Ranking table
--------------
username | criteria | to_be_added | score
--------------------------------------------------
user1 | criteria1 | 1 | 0
[code]....
It means I just set the to_be_added field to 1 for all of them and leave the calculation of score for each criteria for each user to the time the user logins so that to prevent doing all these calculations at once , because there are a huge number of users ... But there is one problem , if I want to show for example the best user (based on the highest score) , the result can't always be true because some users might not logged in at that time and their score might be zero .

Programming :: Implement Left-associative Operators In Parser That Does Not Allow Left Recursion?
Jan 20, 2011The first is about implementing function calls. The way I currently have it is that functions are called with a C++ std::vector of nodes as the parameters. How would I turn a comma-seperated list of expressions into a C++ vector in the grammar?Second, how do you implement left-associative operators in a parser that does not allow left recursion?
And third, what would be the best internal representation of integers? A C++ int seems simplest, but limited. Using GMP seems more versatile, but I'm afraid it might seriously slow down the interpreter compared to C++ ints.
