HEXCURSE(1)						      General Commands Manual						       HEXCURSE(1)

NAME

       hexcurse - an ncurses-based hex editor

SYNOPSIS

       hexcurse [ -?  |  -help ] [ -a ] [ -r rnum ] [ -o outputfile ] [ [ -i ] inputfile ]

DESCRIPTION

       hexcurse  is  an  ncurses-based	hexeditor utility that is able to open, modify, and save a file to disk while providing useful editing and
       searching options.

OPTIONS

       -?  |  -help   Prints out the command usage info

       -a	      Specifies the addresses to be output in decimal format initially.

       -r rnum	      Specifies the number of characters per line that the hexeditor should output.  If rnum is either less than 1 or greater than
		      the columns of the current terminal, hexcurse will fill the terminal width, just as if the -r was not specified.

       -o outputfile  Specifies the output file to be written to by default.

       [-i] inputfile Specifies the input file to be read in.  -i is not needed if inputfile is the last argument on the line.

INTERACTIVE OPTIONS

       F1 | ctrl+?    Shows key command help.

       F2 | ctrl+s    Save the current file.

       F3 | ctrl+o    Opens a file.

       F4 | ctrl+g    Goto  a  certain	location  in  the  current file.  Depending on which way the addresses are being viewed at the moment, the
		      search will behave differently.  If the addresses are currently in hex format, the search will search as if  the	input  was
		      given in hexadecimal format.  If the addresses are in decimal format, the function will search for the address in decimal.

       F5 | ctrl+f    Search  for  a  certain string in the current file.  Depending on which window the user is currently editing in, this search
		      will behave differently.	If editing in the hex window, the input should only be in hexadecimal, and it will search for  the
		      hexadecimal  "string."   If  the	current  editing window is the ASCII window, the input should be ASCII characters, and the
		      search will find that ASCII string in the file.

       F6 | ctrl+a    Switch between hexadecimal address values and decimal address values.

       F7 | TAB       Switch between the hexadecimal and ASCII editing windows.

       F8 | ctrl+q | ctrl+x
		      Exit out of the program.

       Page Up | ctrl+u
		      Scroll one 'page' up.

       Page Down | ctrl+d
		      Scroll one 'page' down.

       Home | ctrl+t  Returns to the top of the file.

       End | ctrl+b   Jumps to the bottom of the file.

       ctrl+z	      Undo the last modification.  Can be used multiple times.

       Esc	      Escapes out of the save, open, goto, and find prompts.

BUGS

       On some terminals the function keys will not work.

       Support for resizable terminals is still a bit rudimentary.  At this time, when the terminal is resized, the cursor is  positioned  at  the
       beginning of the file.  This will be corrected in the next release.  There is also an issue where the labels on the bottom of the screen do
       not resize correctly.  A fix for the latter is in the works.

       To report a bug or problem, please e-mail:

TODO

       When we get the time, we would like to implement the ability to insert and delete data from the file.  Please e-mail us with any additional
       suggestions.

readkey(3alleg4)                                                  Allegro manual                                                  readkey(3alleg4)

NAME

       readkey - Returns the next character from the keyboard buffer. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int readkey();

DESCRIPTION

       Returns  the next character from the keyboard buffer, in ASCII format. If the buffer is empty, it waits until a key is pressed. You can see
       if there are queued keypresses with keypressed().

       The low byte of the return value contains the ASCII code of the key, and the high byte the scancode. The scancode remains the same whatever
       the  state  of  the  shift,  ctrl  and  alt keys, while the ASCII code is affected by shift and ctrl in the normal way (shift changes case,
       ctrl+letter gives the position of that letter in the alphabet, eg. ctrl+A = 1, ctrl+B = 2, etc). Pressing alt+key returns  only  the  scan-
       code, with a zero ASCII code in the low byte. For example:

          int val;
          ...
          val = readkey();
          if ((val & 0xff) == 'd')     /* by ASCII code */
             allegro_message("You pressed 'd'
");

          if ((val >> 8) == KEY_SPACE) /* by scancode */
             allegro_message("You pressed Space
");

          if ((val & 0xff) == 3)       /* ctrl+letter */
             allegro_message("You pressed Control+C
");

          if (val == (KEY_X << 8))     /* alt+letter */
             allegro_message("You pressed Alt+X
");

       This function cannot return character values greater than 255. If you need to read Unicode input, use ureadkey() instead.
