/*
Modeled after the DECSYSTEM-20 command parser (the COMND JSYS), RIP. Features:
. parses and verifies keywords, filenames, text strings, numbers, other data
. displays appropriate menu or help message when user types "?"
. does keyword and filename completion when user types ESC or TAB
. does partial keyword and filename completion
. accepts any unique abbreviation for a keyword
. allows keywords to have attributes, like "invisible" and "abbreviation"
. can supply defaults for fields omitted by user
. provides command retry and recall
. provides character, word, and line deletion (but only from the end)
. accepts input from keyboard, command files, macros, or redirected stdin
. allows for full or half duplex operation, character or line input
. allows \-escapes for special characters
. allows specification of a user exit to expand variables, etc.
. settable prompt, protected from deletion, dynamically re-evaluated each time
. allows chained parse functions.
Functions:
cmsetp - Set prompt (cmprom is prompt string)
cmsavp - Save current prompt
cmgetp = Get current prompt
prompt - Issue prompt
cmini - Clear the command buffer (before parsing a new command)
cmres - Reset command buffer pointers (before reparsing)
cmkey - Parse a keyword or token (also cmkey2)
cmswi - Parse a switch
cmnum - Parse a number
cmifi - Parse an input file name
cmofi - Parse an output file name (also cmifip, cmifi2, ...)
cmdir - Parse a directory name (also cmdirp)
cmfld - Parse an arbitrary field
cmtxt - Parse a text string
cmdate - Parse a date-time string
cmcfm - Parse command confirmation (end of line)
cmfdb - Parse any of a list of the foregoing (chained parse functions)
Return codes:
-9: like -2 except this module already printed the error message
-3: no input provided when required
-2: input was invalid (e.g. not a number when a number was required)
-1: reparse required (user deleted into a preceding field)
0 or greater: success
See individual functions for greater detail.
Before using these routines, the caller should #include "ckucmd.h" and set the
program's prompt by calling cmsetp(). If the file parsing functions cmifi,
cmofi, or cmdir are to be used, this module must be linked with a ck?fio file
system support module for the appropriate system, e.g. ckufio for Unix. If
the caller puts the terminal in character wakeup ("cbreak") mode with no echo,
then these functions will provide line editing -- character, word, and line
deletion, as well as keyword and filename completion upon ESC and help
strings, keyword, or file menus upon '?'. If the caller puts the terminal
into character wakeup/noecho mode, care should be taken to restore it before
exit from or interruption of the program. If the character wakeup mode is not
set, the system's own line editor may be used.
NOTE: Contrary to expectations, many #ifdef's have been added to this module.
Any operation requiring an #ifdef (like clear screen, get character from
keyboard, erase character from screen, etc) should eventually be turned into a
call to a function that is defined in ck?tio.c, but then all the ck?tio.c
modules would have to be changed...
