Programming :: (BASH) Keep Variable In Scope?
Jul 15, 2011i've just started to learn about functions in Bash scripting. I'm able to set the functions and execute the commands correctly. However, if my_var is set in the first function and then later in the script in the script the 2nd function is called, it doesn't seem to remember my_var and quits (at least i suspect this is the problem).
Here's my code (it requires yad available via webupd8. org). My specific problem seems to lay in line #27 where if we view the changelog and then exit that window, it returns to the "main" function but any subsequent commands cause a crash. Is this because of the get command on line #29? It's presumably now out of scope after calling menu on line #25?

Programming :: Get "data Type" Of An "unknown Variable" In "C Language"?
Jun 13, 2009I am going to write a function which will do different operation base on the data type of the input parameter.

The problem is that I do not know how to get the data type of the input parameter in C Language.
Can anyone tell me how to do this.
Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?
Aug 21, 2009I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?
Apr 7, 2010my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't

Jan 30, 2010While reviewing information about chroot, I ran into something called linkage, specifically in reference to legacy and ABI, that they sometimes need to be ran in a chroot because the support libraries might clash in name or linkage with the regular root.

Aug 27, 2010I am interested in learning 3D programming. The thing is, I would hate to put too much effort to learn something that doesn't have future and is dying. My favorite language at the time is Java. My goal is professional programming.
So I have several questions:
1. Should I learn JOGL or start learning C++ and do C++ openGL programming?
2. Is there a big difference between JOGL and C++ openGL programming?
3. Is it worth to learn openGL? Does it have a future?
4. Is it a big difference between openGL and directX coding?
5. If choosing Java, then JOGL or LWJGL?
Why and what is the main difference between them?

View 1 Replies View RelatedProgramming :: What Is Best Language?
Jun 30, 2010My name is Simon and I have recently moved Ubuntu 10.04 from Windows XP. I am a programmer with a few years under my belt using a range of languages but primarily Microsoft Visual Foxpro. This program was very useful as it allowed me to access tables stored on my system and create programs to manipulate data in a wide variety of ways. Programs could be hobbled together, refined then placed in a menu system.I have been looking at a range of packages to use that would (a) allow me the same interactive experience, (b) allow me access to xbase tables (especially as most of the packages and business clients I have use this format), and can be used to create a GUI program. Ideally the package could create programs that can run relatively easily on Linux and Windows. Why, you might ask? Well unfortunately I have not been able to ditch foxpro, it is kind of unique in its abilities. Consequently I am using XP in VirtualBox to do some of my analysis and report production. I also still run Windows on my slate computer, which is used in the field to collect data.I have investigated Python/Jython, Java, Bash, and a number of others (e.g things that interact with PostSQL, MySQL, etc) but happily admit that I am overwhelmed with alternatives. That said, none quite match my relatively simple requirements stated above. The biggest problem is the lack of interactive data manipulation -- e.g. type an SQL statement and have the result appear immediately, that sort of stuff.
I need a language with strong data access, manipulation and reporting capabilities. I have sizable tables/databases containing millions of records and at present most queries take only a seconds using Visual Foxpro. Most of my investigations push me to the MySQL and similar data repositories, but all have their own format. Essentially I need to import all my data into their system before a language can access the data (note that there are copyright issues preventing this in some situations) - aren't there any programs that can access dbase or foxpro tables directly?The programming language also needs to be relatively mature. I don't want to spend all my time defining window sizes and button locations. Editors/Wizards that help design a GUI interface is preferable. It is imperative the language also has strong string, number, array and table access capabilities. Code should also be intuitive and easy to read. A lot of the languages I have reviewed are not intuitive. To me, functions in the format substr(string, start, lengthsegment) is logical and easy to follow. Things like Str = ${str//search/replace/} are not.
I suppose while I am listing preferences, an interpreter like eclipse would be desirable to help maintain code and format it as you go. Some sort of intelligent feedback as you construct a code snippet showing you what alternatives are available would also be valuable.At present I am leaning towards Python with Eclipse as the program manager, but as stated this setup does not really provide an interactive experience and does not appear to naturally interact with dbase. It appears this option would require considerable setup to get working.Java + Eclipse has been suggested before, especially as it takes away the need to worry about operating systems, but most of the packages I have used based on this language are restricted by library development by Sun Microsystems. The file chooser is a classic example - a known bug has been registered for this library for 5+ years and the problem has not been fixed.
