LLREAD: Lightning Logger Reader
© 1988 -1989 Ronald T.Shaw
-------------------------------
LLread, the Lightning Logger reader, offers some varied ways of
obtaining general and precise lists from directory contents saved by the
companion program LLog, Lightning Logger.
At the start of the LLog documentation, a simple run was detailed,
producing a RAM: directory of this issue of JUMPDISK. Let's approach the
reader program the same way.
If you have not turned off your computer since creating the RAM:
directory of JUMPDISK, you may now use the program to work on that file.
1. Start the LLread program and choose LOAD from the pulldown PROJECT
menu at upper left of screen.
2. A requester box appears, asking you to enter logged file's name.
Type:
ram:hold
. . . and click the DONE box.
3. Click on the word FILES at right of screen, and this produces a
volume list -- a list of logged files. If this is your first try, the only
entry should be the letter J -- for JUMPDISK. Click on the J and then click
the word LOAD at the bottom of the box.
4. The options beneath the word LIST at right are activated. They are
DIR, OPT A, CD and LIST.
5. Click on the word LIST, and you will see an AmigaDOS-style list of
files, as they are stored by the logger program.
6. Next, go to the pulldown PROJECT at top left of screen and choose
the word PRT:. This activates the printer so any display you request will
be put on paper. You may return control to screen display by choosing
PRT: a second time. The control toggles back and forth.
There are more involved operations, which will be covered along with
some standard information given in more detail.
In addition to clicking the program icon to start it, a CLI/Shell start
is also possible. As the program exists on JUMPDISK, the command would be:
"j:lighting logger/llread" <press Return)
. . . with the quote marks included.
Clicking on the bottom window gadget, which shows the name of the
volume, will bring up a window with information about the currently loaded
volume.
AUTO LOAD OF DEFAULT FILE
This provides for standard lists of SKIP VOLUMES, SKIP DIRECTORIES and
SERIES. It pre-loads a default logger file. This default file must have the
following format and can be created by ED, EDIT and most other text editors.
It must exist in the sys:s directory and be named:
llg.def
Using this file is one of the best reasons why the Lightning Logger
programs should be put on a bootable Workbench disk for full use. Here is
format:
VOL-SKIP list:
|VOL_SKIP|+,vol name,vol name, etc.
(+ means turn on the VOL-SKIP gadget)
|DIR_SKIP|+,dir name,dir name etc.
|SERIES|,volume series name
|DEFFILE|,vol:path/name
SAMPLE DEFAULT FILE:
|VOL_SKIP|+,a*,bar*,pix,Work*
|DIR_SKIP|,c,lib,fonts,devs,s,empty,t
|DEFFILE|,sys:t/mylib
|SERIES|,music
DEFAULT FILE MEANINGS
1. Insert ITEMS in volume skip list and turn on VOL-SKIP gadget.
2. When searching, skip all volumes beginning with the letters "a,"
"bar" and "Work" or named "pix."
3. Insert items in directory skip list, don't turn on DIR-SKIP gadget,
when searching SKIP all c, lib, fonts, devs, s, empty and t directories.
4. Load Logger file named music located in sys:t directory.
5. The series to use if series-search selected is music. This is useful
if you have a series of volumes such as MUSIC1, MUSIC2, MUSIC3, etc.
FILTER MENU
VOL-SKIP: Allows bypass of selected volumes while searching. Note: The
VOL-SKIP gadget must be activated.
Wild card can be used to skip volumes.
Entering A* skips all volumes beginning with the letter "A" and "a."
Lightning Logger ignores differences between upper and lower case.
DIR-SKIP: Works much like VOL-SKIP but doesn't allow wild cards.
Example:
Entering c, lib, libs, empty, printers, devs, fonts, etc., will skip
these directories when searching.
SEARCH: Has three modes (wild card activated).
mode 1: Name searches through volumes to find matching file names.
mode 2: Note searches to find matching file notes.
mode 3: Both searches for matching file names and file notes.
Example: To search for all files with a ".c" extension.
1. Select search from filter menu.
2. Select name from sub-menu.
3. Type *.c in the requester that appears.
4. If volumes are entered in volume skip list, click on VOL-SKIP
gadget, which turns color when activated. If directories entered in
directory skip list, click on DIR-SKIP gadget. If series is entered, click
on SERIES-SEARCH and search begins. All file names ending in ".c" will be
displayed on screen. If match memory is available, these matches will be
held in memory to be recalled with the redisplay button until cleared, when
the next search begins.
SERIES
If you have a series of similarly named volumes (example: ART1, ART2
... ART3) and you wish to search the series, select SERIES from the filter
menu and enter ART (not the number) and enter the item to seek. Then click
on the SERS-SEARCH gadget, and search will only search volumes belonging to
this series. You can abort the search at any time with the abort button.
VOL-SKIP: If selected and volumes are entered into volume skip list,
the reader will bypass these volumes when searching.
DIR-SKIP: If selected and directories are entered into dir skip list,
the reader bypasses these directories when searching.
SERS-SRCH: Only searches volumes in a numbered series.
GO-SEARCH: Searches all volumes, unless VOL-SKIP activated.
RE-DISPLAY: If matching items are found and match memory is on and set,
these matching items can be re-displayed or printed. Re-display can be
aborted by using the ABORT gadget.
FILES: Brings up window with logged volumes. Clicking on the volume
name and then clicking on LOAD will put this volume's files in memory for
display or printing. Once the volumes files are loaded, the volume name and
creation date are displayed. Clicking on this gadget opens a window that
displays pertinent information about the selected volume. When a volume is
selected and its files are loaded, the list, opt a, cd and dir gadgets are
activated. They work similarly to the AmigaDOS commands with the same names,
but there are a few exceptions. When using the "CD" gadget, entering ROOT:
takes you back to the root directory of that volume. DIR, OPT A and LIST
display files and file notes. Filenotes begin with ":" and are a different
color than the regular entries.
MEMORY BUFFER
The memory buffer can be used to select the amount of memory LLread
uses to hold volume records. This allows the reader to make a very fast
search without going back to the disk file to re-read records -- once these
records have been read once.
FILE displays the amount of memory in kilobytes reserved by the reader
to hold records in memory.
MTCH displays to amount of memory reserved for matching items.
To increase or decrease FILE or MTCH, click on the number, click on UP
or DN, and digits will change accordingly. If some of the memory is in use,
the USE gadgets to the left will be displayed in color. To free memory in
the USED gadgets, click on the USED gadget and the memory will be freed.
If the MTCH memory buffer is set to ZERO and items are found while
searching, these items cannot be redisplayed because there is no memory
buffer set for these items.
TO THE PRINTER
To print out only a list of volumes logged, select volume List from the
MISC menu.
To print out a complete listing of the library and files, select File
List from the MISC menu under Volume PRT.
To print out screen displays or matches, turn printer on from Menu
"PRT:" and turn on your printer. Don't forget to set your printer in
Preferences.
ON DISK
To save a file on disk:
1. Click on CMD in your Workbench system drawer.
2. Set prt: or select print option in LLread.
CL GADGET
At the bottom right corner of the LLread Window is a CL gadget.
Clicking on it resizes the LLread window, which allows access to windows
behind LLread. Clicking again on the CL gadget brings LLread back to full
size.
