|
*
|
|
* HISTORY
|
|
* 22-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Removed checks for VIRTUE window manager. If they don't like
|
|
* it then they can fix the more program.
|
|
*
|
|
* 08-May-85 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Increased MAXENTRIES and MAXHELPS from 200 to 400.
|
|
*
|
|
* 30-Apr-85 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Adapted for 4.2 UNIX. Added calls to check for
|
|
* using window manager of VIRTUE.
|
|
*
|
|
* 29-Apr-85 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added two small bug fixes (courtesy of Richard Cohn).
|
|
*
|
|
* 14-Aug-84 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added fflush(stdout) after printing prompt, before asking for input line.
|
|
*
|
|
* 01-Jul-83 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Bug fix: whitespace now required before ">filename" and not permitted
|
|
* within or after filename.
|
|
*
|
|
* 06-Jun-83 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Bug fix: added line to initialize "redirected" to 0.
|
|
*
|
|
* 20-May-83 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added quiet bits CINOSEM, CINOFILE, CIFIRSTEQUAL to allow user to
|
|
* have special characters ; > = treated as normal data (except =
|
|
* after first argument, which still means "variable assignment").
|
|
* Also added output redirection via >filename on input line.
|
|
*
|
|
* 07-Mar-83 Dave McKeown (dmm) at Carnegie-Mellon University
|
|
* (Slight alterations by Steve Shafer.)
|
|
* Made cidepth a global, used for recursive and nested calls to
|
|
* ci(), and accessable to the user. Added '@x' command, similar
|
|
* to '^x' except that the previous command interpreter name is
|
|
* remembered and after 'x' is executed, the previous command
|
|
* interpreter is reinvoked. Users who plan to use this feature
|
|
* must save the name of the previous ci in global variable
|
|
* 'ciprev' after exit from the ci(). ie.
|
|
* ci(.........);
|
|
* strcpy(ciprev,"ci-name");
|
|
* Added ci state CICMDNOINDENT to allow for no indentation of the
|
|
* command line prompt based on cidepth.
|
|
* Reduced amount of indentation on source code.
|
|
* Bug: the "depth" argument is now a no-op, retained for backward
|
|
* compatibility. Cidepth is initialized to zero, and incremented
|
|
* upon invocation of a ci(). If cidepth is <1 then you are not
|
|
* in a ci() instantiation.
|
|
*
|
|
* 21-Feb-83 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added up-arrow (^) command (and variable cinext). ^x is used when
|
|
* you have a ci program in which one command invokes ci with a
|
|
* new set of commands (i.e. a subsystem of the program). Inside the
|
|
* subsystem, ^x will exit the subsystem, and cause the main level
|
|
* to execute the command line "x" before reading more input lines.
|
|
* The cinext variable is used to implement this. Cinext can also be
|
|
* used by any user code which desires to force ci to execute a
|
|
* specific command before reading more input from the current file.
|
|
*
|
|
* 16-Jul-82 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added extra code in _ci_help to eliminate duplicate help file
|
|
* names. This way, if several directories are specified and there
|
|
* is are files with the same name in more than one directory, only
|
|
* the first of each file will be included in the help list.
|
|
*
|
|
* It would have been nice to do this after the qsort instead of
|
|
* before (in ci_help). However, qsort does not ensure that
|
|
* "equivalent" entries are kept in the same relative
|
|
* order; thus there would be no way to ensure that the
|
|
* file being used was the first such file found.
|
|
*
|
|
* 07-Jul-82 William Chiles (wpc) at Carnegie-Mellon University
|
|
* Modified so that "!" invokes shell commands from the type of
|
|
* shell specified by the environment variable SHELL. If SHELL
|
|
* is not defined the standard shell is used.
|
|
*
|
|
* 21-Sep-81 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Increased LINELENGTH (input buffer length) to 1100 to satisfy
|
|
* voracious requirements of a certain user whose name I won't mention
|
|
* but whose initials are "faa".
|
|
*
|
|
* 08-Oct-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added class variables: ci_tclass cases in ci_show and ci_set.
|
|
* Also added CICMDFPEEK in addition to existing CISETPEEK.
|
|
*
|
|
* 22-May-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Ci now sorts help topics into alphabetical order. Some interrupt
|
|
* handling has been added, but there are bugs, for example, when
|
|
* you interrupt "*" (the listing of command names). The right thing
|
|
* happens, but bogus messages are printed.
|
|
*
|
|
* 16-Apr-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Ci now prints lists of names with prstab(). This uses multiple
|
|
* columns when appropriate.
|
|
*
|
|
* 12-Mar-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added code to skip over leading blanks and tabs in the argument list
|
|
* when executing commands, and setting and displaying variables.
|
|
* Also fixed meta-help, which mysteriously disappeared.
|
|
*
|
|
* 19-Feb-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Added "if (0) del();" to force del() routine to be loaded. This is
|
|
* the safest way I know of to define the external int "_del_". If you
|
|
* don't believe it, think again about separately compiled files.
|
|
*
|
|
* 28-Jan-80 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Created. Patterned (somewhat) after ci() on PDP-11.
