This is shmed, version 1.0, a simple editor that gives a shell or perl
program form editing capabilities for user input. After reading in a
file specifying the form, it is displayed on the screen and the user can
edit it. Upon exit, shmed writes out the variable assignment statements
to another file which can then be source'd (or .'d or do'd) by the
shell. See the manual page for the details.

XThis is shmed, version 1.0, a simple editor that gives a shell or perl
Xprogram form editing capabilities for user input. After reading in a
Xfile specifying the form, it is displayed on the screen and the user can
Xedit it. Upon exit, shmed writes out the variable assignment statements
Xto another file which can then be source'd (or .'d or do'd) by the
Xshell. See the manual page for the details.

X Permission is granted to anyone to use this software for any
X purpose on any computer system, and to redistribute it freely,

X 1. The author is not responsible for the consequences of use of
X this software, no matter how awful, even if they arise
X from defects in it.
X
X 2. The origin of this software must not be misrepresented, either
X by explicit claim or by omission.
X
X 3. Altered versions must be plainly marked as such, and must not
X be misrepresented as being the original software.
X
XInstallation:
X
X1) Edit the Makefile and change the options at the top of the file if
Xyou don't like them.
X
X2) Run "make". This should produce the executable "shmed".
X
X3) Run "shmed -f testform -o outfile" to try it out. Check the outfile to
Xsee what is produced. A trivial perl example is in the file perldemo and one
Xfor the shell is in shdemo. Roff is a more complex and possibly even useful
Xsh program.
X
X4) Run "make install" to put the binary and man page in the correct place.
X
XShmed uses the curses library (the BSD version). It has been tested under
XSunOS 4.1, BSD 4.3 (actually mt Xinu MORE/BSD), and the Next machine,
Xalthough not a whole lot (this IS version 1.0).
X
XPlease report any bugs or improvements to me.

XNote: There was another shell form editor, "sf" by Paul Lew, which came out
Xon the net a few years ago. I used it for a while, but found that it did
Xbizarre things with reverse video mode on some of our terminals. After a
Xnot-too-lengthy look at the sf code I decided that it would be easier to
Xwrite my own than try to find the problem and fix it. Although, sf inspired
Xthe writing of it, shmed is completely different and of course, the code and
Xinternal structure are not the same. Ditto for the format of the form
Xdefintion file. If you're interested, sf can be found in the archives of
Xcomp.sources.unix, volume 14 under the name "shellforms".

Xshmed - simple shell form editor
X.SH USAGE
X.nf
Xshmed [-pbc] [-f formfile] -o outfile
X-p perl output (default)
X-b Bourne shell output
X-c csh output
X-f file form template file (default stdin)
X-o file name of output file (no default)
X.SH DIAGNOSTICS
Xshmed returns non-zero if there are startup
Xproblems or if it is interrupted, else 0.
X.SH FILES
XFormat of the form template file
X.RS
XNormal text lines are printed as they appear.
XEditable lines should begin with a '.' (dot), and
Xcontain 2 or 3 fields separated by a '~' (tilde).
X.RS
X1st field: label to be printed in the editor.
X.br
X2nd field: name of variable to assign the value to

X.RE
X.RE
X.RS
XOutput file
X.RS
XThe output file contains a bunch of variable assignments
Xin the language you selected (perl, sh, or csh). It should
Xbe do'd, .'d, or source'd after shmed is run.

XThe Shmed Form Template
X
XA form template consists of up to 24 lines of text (actually you
Xcan have more than 24 lines in the file, but anything beyond 24
Xwill be ignored). Ordinary text lines will be printed on the screen
Xjust as they are. However, a line which begins with a dot (.) denotes
Xan editable line. This line consists of either 2 or 3 fields separated
Xby a tilde (~). The first field is the label that will be printed
Xon the line; the second field is the name of the variable that will
Xbe assigned to; and the third field, if present, is a default string
Xthat will be printed.
X
XFor example, the file containing
X
X.Your name~nombre~Albert Q. Shmurdwell
X
Xwill produce a line on the editor that looks like
X
XYour name: Albert Q. Shmurdwell
X ^------- (cursor will be here)
X
XThe user can then edit the line and change it if their name is not
XAlbert Q. Shmurdwell. After they have exited the editor, an assignment
Xstatement such as
X
Xnombre='Albert Q. Shmurdwell'
X
Xwill be written into the output file (if you are using the -b option
Xfor Bourne shell output).
X
XLook at the sample files provided for more elaborate examples
Xof template files.
