- FANLED - a FANcy Line EDitor for TurboDOS
-
-
-
- FANLED is a TurboDOS module designed to allow sophisticated line editing
- capabilities on the TurboDOS command line. It completely replaces the
- INPLN module supplied by Software 2000. FANLED has been tested on TurboDOS
- version 1.41 systems and may not work in pre-1.4x versions.
-
-
- =========================================================================
- THIS IS THE RELEASE VERSION OF FANLED. PLEASE FOLLOW ALL INSTRUCTIONS TO
- BRING IT UP. PASS IT ON TO A FRIEND. IF YOU USE IT COMMERCIALLY, YOU'RE
- WELCOME TO DO SO, BUT PLEASE LET ME KNOW. THANKS.

-
- 1. INSTALLATION
-
- FANLED can be installed two ways: (8 bit version)
- 1 If you have PACKAGE.COM and all kernel modules, simply replace "INPLN"
- in the .PKG files with "FANLED" and use the PACKAGE command to generate
- new STDxxxxx.REL files.
- 2 If you do not have PACKAGE.COM, you will need a library manager, such as
- Digital Research's LIB.COM (comes with RMAC and CB80) to replace INPLN
- with FANLED in all STDxxxxx.REL files. Example:
- 0A}LIB STDSLAVE=STDSLAVE<INPLN=FANLED>
-
- Method 1 above also works for 16 bit systems. If you don't have the PKG
- files and PACKAGE.CMD, you are almost out of luck unless your OEM or
- systems house can supply DELINK and RELINK. DELINK changed a .O file into
- its mapping information, while RELINK restores the .O file. You would have
- to use DELINK and an editor to remove the INPLN module, put the DELINKed
- version of FANLED in its place (be sure to remove the EOF) and then RELINK
- the whole mess. It may be better to just RELINK STDSLAVE.O without
- FANLED and put FANLED in the GEN file so it can be updated easier.
-
-
- In your PAR file, be sure to include FORSPC = "^n" where "^n" is the
- control character that causes your video display to space forward non-
- destructively. The default is:
- FORSPC = "^L"
- which is common to many terminals.
-
- In order to save space, your command line buffer should not exceed 160
- characters. If you do not use "CLBLEN = " in your PAR file, you are
- safe, else be sure CLBLEN = 9B (default value). Future versions of FANLED
- will allocate buffer space dynamically.
-
- Now re-GEN your SYS files and you're ready to roll...
-
-
- 2. FEATURES
-
- FANLED provides the following editing features on the command line:
- - recall of last command line (only if recall executed before anything
- else is typed)
- - cursor movement forward and backward character-wise, as well as move
- cursor to beginning or end of line
- - delete character forward or backward
- - delete all characters left of cursor
- - delete all characters right of cursor
- - insert character at cursor position
- - yank kill buffer (undo last delete, inserting at current cursor
- position).
-
-
- 3. DETAILED COMMAND DESCRIPTION
-
- The FANLED command set is based on the EMACS command set as used in the
- MINCE editor and other Mark Of The Unicorn products.
-
- 3.0 The cursor
- The cursor is defined as placed BETWEEN two characters. The
- character displayed to the left of the cursor is the character
- assumed to be to the left, the character displayed above the
- cursor (or overstriking the cursor, whichever cursor mode
- your terminal may be in) is considered to be to the right
- of the cursor.
- Note that if your command line is longer than can be displayed on
- one terminal line, the terminal must be in WRAPAROUND mode for
- FANLED to work properly!
- 3.1 Entering a command line
- A command line is entered as usual with a RETURN terminating it
- and causing it to be executed.
- 3.2 Recalling previous command line
- ^R The previous command line can be recalled by typing ^R at the
- system prompt. Typing ^R as any character other than the first
- causes the ^R to be ignored and not acted upon. After a line
- recall, the cursor is positioned at the end of the line.
- 3.3 Cursor movement
- ^F ^B The cursor is moved forward by pressing ^F and backward by
- pressing ^B. If the cursor is at the beginning of a line, ^B
- will be ignored. If the cursor is at the end of a line,
- ^F will be ignored.
- ^A ^E The cursor is moved to the beginning of the line by pressing ^A.
- The cursor is moved to the end of the line by pressing ^E.
- 3.4 Delete character
- ^D ^H Pressing ^D causes the character in front of the cursor to be
- deleted, moving the remainder of the line to the left by one
- character. Pressing ^D at the end of a line will be ignored.
- Pressing ^H (or the BACKSPACE or DELETE key) causes the character
- to the left of the cursor to be deleted. Attempts to delete
- past the beginning of the line will be ignored.
- 3.5 Kill characters
- ^K ^X Pressing ^K will cause all characters to the right of the cursor
- to be deleted and placed into the kill buffer, overwriting the
- current contents of the kill buffer. Pressing ^X causes all
- all characters to the left of the cursor to be deleted and placed
- in the kill buffer, overwriting the previous contents of the kill
- buffer and moving all characters to the right of the cursor to
- the beginning of the line.
- ^K and ^X become invalid if there is nothing to be killed, without
- altering the kill buffer contents.
- 3.6 Unkill characters
- ^Y Typing ^Y will cause the contents of the kill buffer to be
- inserted at the current cursor position. Note that the contents
- of the kill buffer will be retained until the next ^K or ^X is
- executed. This allows for a simple 1-line storage...
- 3.7 Inserting editing characters as control characters
- ^Q Typing ^Q will cause the NEXT character to be inserted into the
- command line. Use it to insert one of the edit command characters
- into the command line. A RETURN cannot be inserted.
- 3.8 Terminate and execute
- RET Typing RETURN (ENTER, ^M) causes the whole command line to be
- sent to TurboDOS for execution, even if the cursor is positioned
- somewhere other than at the end of the line.
- 3.9 USE OF FANLED
- FANLED is invoked automatically at the operating system prompt
- and (!!) when C-function 10 is executed. Many programs use
- C-function 10 to obtain string-oriented input!
-
-
- 4. COMPATIBILITY
-
- FANLED's advanced features can, of course, only be used on video terminals.
- If the terminal has an AUTO-CRLF or WRAPAROUND mode, it should be enabled
- so the editing features can be used on a command line longer than what fits
- on one terminal line.
-
-
- 5. LEGAL STUFF AND SUCH
-
- FANLED was written for unlimited distribution. Its object code is placed
- into the Public Domain with the only restriction that it be used only by
- licensed users of the TurboDOS operating system. Companies wishing to
- include FANLED into systems sold to their customers should notify me of
- such use, however, no royalties, license agreements and other such useless
- junk will be necessary. I just want to know who uses it.
- OEM houses and large volume system integrators with competent systems level
- programmers may obtain the source to FANLED by sending me a diskette with
- sufficient return postage. 8" SSSD CP/M or any ICM format (8") is fine.

- UPDATE INFO:
-
- ver 1.00 4-2-85 initial release
- ver 1.10 4-4-85 fixed minor bug in insert routine
- ver 1.20 4-9-85 added globals for edit keydefs:
- GLOBAL PATCH POINTS AND THEIR DEFAULTS:
-
- FANBG = "^A" ; MOVE CURSOR TO BEGINNING OF LINE
- FANBK = "^B" ; MOVE CURSOR BACKWARD 1 CHARACTER
- FANEL = "^E" ; MOVE CURSOR TO END OF LINE
- FANFC = "^F" ; MOVE CURSOR FORWARD 1 CHARACTER
- FANDF = "^D" ; DELETE CHARACTER FORWARD
- FANDB = "^H" ; DELETE CHARACTER BACKWARD
- FANKF = "^K" ; KILL ALL CHARACTERS FORWARD
- FANQU = "^Q" ; INSERT NEXT CHARACTER (QUOTE)
- FANRC = "^R" ; RECALL PREVIOUS COMMAND LINE
- FANKB = "^X" ; KILL ALL CHARACTERS BACKWARD
- FANYA = "^Y" ; YANK KILL BUFFER INTO COMMAND LINE
-
- Thanks to Chris Loelke for his suggestions. Multiline storage is a
- question of memory and I may not implement it.
-
- The source to FANLED will be available soon.
-
- Continued update info as of 14 Jul 85:
-
- v1.40 fixes the ^Y problem, the obscure 16-bit bugs and adds the
- ^U command (cancel current command line).
- v1.40 16 bit ONLY adds the following new commands:
-
- ^G PUSH current kill buffer
- ^T POP current kill buffer
-
- This is a 1-level stack, if the stack is in use, nothing may be pushed.
- If the stack is empty, nothing may be popped. It can be used as a means
- to save the current contents of the kill buffer.
- This set of commands may at one point be expanded to allow multi-line
- storage through a "push" and a "pop n" command.
- I have made no effort to incorporate these features into the 8-bit version.
- NQU = "^Q" ; INSERT NEXT CHARACTER (QUOTE)
- FANRC = "^R" ; RECALL PREVIOUS COMMAND LINE
- FANKB = "^X" ; KILL ALL CHARACTER
