version control - How do I go about splitting Lisp code into multiple source files? -

-

Now, whatever I fit in a source file, and how you decide on it a surprisingly small How much and different is that in different files?

With Java, it's easy to decide what happens in a file (the decision has already been made for you), but I think I write several small functions which It is difficult to determine and it is difficult to decide if anything should be divided, as I have resolved big projects in Lisp, it will not be good to change the wheel again, but let me know about it Switch to was not a lot of concrete information on the web.

Can you share some strategies to deal with big projects in Lisp, or to point me out some resources to deal with this issue?

When you start to write a Lisp program, it may be useful to start with a file . Once the code gets very big (whatever it is) you can divide it

Some signals:

  • Some tools for managing the source There are file dependencies and functions such as compilation, load, compile-load and others. ASDF is one, but there are others too.

  • To describe dependency , you need a file to name it so that it can be recognized.

  • You may need to define one or more packages .

  • You may have to enter implementation specific procedures in your own files.

  • Configuration data for your files

  • General Utilities Another file should be

  • Macros must be defined before using other files depending on the file and the macro definition changes. , Then it should be automatically compiled again.

  • Group functionality together in a file if it is logically linked to the drawing program: All drawing functions, all user interface commands, printing in files, printing, ...

  • Do not care too much about the file size. Lisp source files can sometimes be larger than 100k

  • Moving the files is supported by the development environment. M.

  • Ensure that you can reload the file without restarting the entire Lisp.

  • Commonly load tasks as load and COMPILE-FILE provides you can use these functions in your files.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
