+-----------------------------------------------------------------------+ | Atree v1.7 Copyright 1989 (pending) | +-----------------------------------------------------------------------+ | A directory utility by Don Schmidt | +-----------------------------------------------------------------------+ To print Atree.Doc, at you CLI prompt enter: "type > prt: atree.doc" <CR>. Atree v1.7 -- November 6, 1989. This version of Atree is much improved over the previous version. Many bugs have been removed, improvements made, and options added. This version is not fully functional -- it contains options that do not work. Options that do not work will present a requester indicating that you are not registered. You may obtain a fully functional version of Atree by sending me $25.00. You will then be entitled to upgrades as they are released. Send cash, check, or money order to: Don Schmidt 9425 Stanfield Ct. Stockton, Calif. 95209 The author can be reached via COMPUSERVE PIN #73520,314. Comments, criticisms, suggestions and bug reports are welcomed. Atree has no warranty or guarantee. The author assumes no responsibility whatsoever for any effects, good or bad, that Atree may have on hardware or software. No portion of this program was intentionally designed by its author to do any damage to hardware or software or to cause any destruction or distortion of any data, i.e., it contains no intentional trojan horses or viruses of any kind. However, it is advised that caution be used with versions of the program not received directly from the author. ************************************** About Atree: ************************************** Atree is a disk utility which imitates similar utilities widely available on IBM compatibles (PC Tools, XTree, QuickDos, etc.). The intent is to allow the user a graphic representation of the entire (or any portion of the entire) directory structure on a disk device, including the files in each directory, and the capability of moving quickly through the "tree" to a directory to access its files for purposes of copying, deleting, moving, viewing, editing, executing, etc. Atree currently supports and will read into memory a directory tree that has a maximum depth of 65536 directories and no more than 65536 subdirectories total for the entire tree. (This is because Atree currently supports a spreadsheet type matrix of 65536 columns, each column representing the subdirectories of a parent directory and 65536 rows representing a directory with the first of its children directly to the right of it, and only a total of 65536 rows currently supported). It is not known how the program will behave if the total number of directories in a tree exceeds 65536 or if the depth of the tree exceeds 65536 generations. Although Atree can support a maximum depth of 65536 directories not to exceed 65536 directories total in all directories for display purposes, it can only support a maximum depth of 512 directories for purposes of deleting, moving, copying, pruning, and grafting, or using any other function requiring a LOCK on a directory. Additionaly, there are more stringent limitations involved in the use of the "Replace from here" and similar routines (see the descriptions of such functions below under the "Tree Menu"). **************************************** Atree Instructions: **************************************** NOTE: If you are a first time user of Atree and do not have a file called "Atree.Config" in your s: directory, then running Atree will result in a requester indicating "Failed: Object not found" -- select "CONTINUE" and Atree will continue to load and initialize without problem. You should set up your config file during your first session; see instructions for the CONFIG menu below. If you are a user of a previous version of a Atree and are using this version for the first time, it is recommended that you delete or move the Atree.Config file from your s: directory and redefine your configs on your first run of this version. This version of Atree has an "Atree.Config" file accompanying it. If you wish, copy this file to your s: directory before running Atree. At least you will have some pleasant colors in your first session. ********************************************* Running the program. ********************************************* Atree Operates only from the CLI. The general format of the command should be: "run atree pathname pathname pathname ......". Examples: run atree df0: df1: dh0: ram: df1:utilities df1:pictures/flowers The above reads into memory six trees. The first four will be read from the ROOT directory of the indicated devices, and the last two will be trees read from the indicated subdirectories of the indicated devices. run atree dh1: dh1:c_sources dh1:c_objects The above reads into memory the three trees from the same device, dh1: The first tree will be the entire tree starting with the ROOT directory, and the second and third will be the subtrees starting with the c_sources and c_objects directories respectively. run atree df0: df0: df0: The above reads into memory the entire tree of df0: three times -- no good reason for doing it, but it can be done. run atree volume_1: volume_2: volume_3: The above reads the entire tree starting from the ROOT directory of three disks whose volume names are as indicated. The system will prompt you to insert the volume in any drive if not already inserted. A two drive system can thus be used to read into memory the directory trees of more than two disks and as many as the system's memory will support. run atree The above command line has no arguments and therefore atree will read into memory the entire subtree starting from the current directory specified for the operating system. Reading into memory only the parts or sections of a directory tree may be the desirable course if you are using a hard disk that has extensive directories and you only intend to use two or more small portions of the entire tree. As many pathnames may be entered as the command line will support (Total of 255 characters). *********************************************** Getting Atree out of the Way *********************************************** Once Atree is up and running, you may want to get it off of your screen. The Atree window is on its own screen. You may use the mouse pointer to grab the window drag bar and drag the window down a few millimeters. Then you can grab the screen drag bar behind it and move the screen down to the bottom of your display. You can also drag the window down to expose the screen's front_to_back gadget and click on it to put the Atree screen behind any other screens present. Atree can also be ICONIFIED. Select "Iconify" from the "Utils" menu and the program will be shrunk to a very small window that can be dragged or placed behind other screens. Click the mouse on the word "Atree" in this small window and the Atree program will be activated. *********************************************** Moving around in the directory and files: *********************************************** The currently selected directory tree is shown in a large box at the left of the screen under the word "DIRECTORY:". This box can be thought of as a window to a larger box containing the entire tree. The entire tree can be thought of as represented on a large spreadsheet with 65536 rows and 65536 columns. In this spreadsheet, a tree is formed which graphically represents parent, child and sibling relationships between directories. Children of the same parent (siblings) will all be in the same column; the parent of any directory is always in the column to the left, and the children of any directory are always in the column to the right. Line segments between directories show how they are related. The directory box at any moment displays up to five generations (columns) of directories, and up to sixteen rows. You may use either the mouse pointer in combination with the left mouse button, or the UP, DOWN, RIGHT, and LEFT arrow keys to scroll the directory "window" to display different sections of the whole tree spreadsheet, as explained below. To the right of the directory box is another box just under the word "FILES". This box lists up to sixteen files in the currently highlighted directory. You may use either the mouse pointer in conjunction with the left mouse button, or the shifted UP and shifted DOWN arrow keys to scroll through the entire list of files in the currently highlighted directory, as explained below. On the display screen, there will always be one directory and one file that are highlighted. The highlighted file or directory is understood to be the "argument" or "object" of the various commands you can select from the keyboard or menus. Only the first eight (8) characters of directory names are shown in the directory box; the full name of the currently highlighted directory is displayed to the right of the word "DIRECTORY:" above the directory display box. Only the first twenty-five (25) characters of file names are displayed in the FILES box. To see the full file name, select the RENAME/FILE option from the ATTRIBUTE menu. Cursor keys used alone move the highlighter in the directory box. Shift/UP Shift/DOWN move the highlighter in the files box. Click left mouse button on any legitimate directory or file and highlighter will move to it, skipping over anything between. Hold left mouse button down and move pointer -- highlighter will follow it. Clicking or holding the left button down with pointer close to the edge of either the directory or files boxes will cause display to scroll if there is anything to scroll to. The pointer with button held down functions according to the same rules as the cursor keys, no matter where on the edge of the screen the pointer is located. The position of the highlighter is what's important. Thus, if the highlighter is on a directory at the lower edge of the box and the directory has no entries in the same column below it, then no matter where you hold the pointer at the lower edge of the box, no scrolling will occur. But if you move the highlighter to a directory that does have entries in the same column below it, then no matter where you hold the pointer along the lower edge of the directory box, it will scroll. Atree also allows you to mark your place at up to three directories in any tree and to return to a marked place from any tree (See the description of the functions in the Directory Menu below). Tag files: Files in a directory can be tagged. The tagged files constitute a group that can be operated on as a unit for purposes of copying, moving, deleting, archiving, etc. To tag a file, move highlighter to file and press space bar (Directories can't be tagged). Once tagged, files remain tagged until an operation is performed on them. You thus may move to another directory to perform other operations and return later to the directory containing tagged files and the files will still be tagged. Tagged files are marked with the ">" symbol immediately to their left. You may remove the tag from a file by placing the highlighter over the file and pressing the space bar. ****************************************************** Using the Atree menus: ****************************************************** Tree Menu: ---------------------- Read next: changes the currently displayed directory tree by rotating through directory trees previously read into memory. Thus, if you have read into memory df0:, df1:, and dh0:, then selecting this option will cause the "next" tree to be displayed; "next" is determined by the currently displayed tree and the order in which the trees were read into memory, which, in turn, is determined by the order in which you entered the names on the command line. Get (replace): replaces currently displayed tree with a new one you specify. Get (new): reads into memory a new tree you specify and displays it. This will be a new tree in addition to the others currently read into memory. The user can thus read into memory a number of trees limited only by available memory after the program has been activated. Erase: Deletes the currently displayed tree. (You can't delete the last or only tree -- there must always be at least one tree). Info: Displays disk info, like how many bytes and blocks are free. Note that floppy 3.5 inch disks have 512 bytes per sector, but 24 of these bytes are reserved by the system. Therefore, the correct number of bytes usable by the user is 488 bytes per block multiplied by the total number of blocks available, and that is the figure used here. Also note that 512 bytes per block are usable on hard disks. Show Memory: Displays total CHIP and FAST memory available. Set Max Depth: This option gives Atree some real flexibility. It allows the user to specify the depth to which any subsequently specified tree will be read from a disk. A depth of 0 means no depth is specified and Atree will read all directories it can. A depth of one (1) means only the subdirectories and files of the specified starting directory for the tree will be read. By specifying a depth of one (1), and by using a combination of the options "Replace from here" and "Add from here", the user can weave his way into a disk directory system one layer at a time. There may be a very real time savings by using this method. The current setting of the Max Depth variable is saved to the Config file described below. From that point on, Atree will use the setting in the Config file upon running the program. In addition, the functions "Read back (add)" and "Read back (replace)" allow the user to weave his way back out of a disk directory system. Replace from here: This option replaces the currently displayed tree with a new one that starts with the highlighted directory. Used in conjunction with a Max Depth setting, the user can penetrate only those portions of the directory that are of interest as an alternative to reading the entire tree. Add from here: This option functions the same as the "Replace from here" option described above, except that a new tree is created and becomes the displayed tree; the old one still remains. Read back (add): Allows the user to "back up" in a tree. For example, suppose you have just read your way into a directory such that your currently displayed tree represents everything from a depth of 15 to 18 from a particular directory and that your maxdepth for reads is set at 3. Selecting this option will cause the reading of a new tree. The new tree will be derived by selecting the parent's parent's parent of the old tree's top directory and use the path to that new directory as the basis for reading the newly added tree to a depth of three. In other words, from the top directory, we "back up" maxdepth levels in the top directory's direct line of descent and then read from that ancestral directory to a depth of maxdepth; in our example, we would end up with a depth of 12 to 15. Read back (replace): Functions the same as "Read back (add)" except that the new tree replaces the old tree. NOTE: The four options starting with "Replace from here" create a directory path string representing the complete path specification of the currently highlighted directory -- the tree is then read just as though the user had typed the path on the CLI command line on running Atree. The size of this string is limited to 2048 characters. These functions therefore can support a minimum depth of about 51 directories (if each has a 40 character name), and a maximum of about 1000 or so directories (if each is assumed to have a one character name). This should be quite sufficient for nearly all applications. Attribute Menu: ----------------------- Note: Allows FileNote on highlighted directory/file. Protection: Allows change of protection status on highlighted directory/file. Rename: Allows renaming of highlighted file/directory. In all of the above cases, you can select the attribute from the menu to see or view the current specification and, if you wish, you can click on the string gadget to alter the current specification. Directory Menu: ---------------------- Delete: deletes all files in highlighted directory and deletes directory if there are no subdirectories. NOTE: This routine ignores delete protection -- the user must be sure that none of the files in the directory are wanted. Make: creates a subdirectory in the highlighted directory. Reread Files: Updates the memory list of files contained in the highlighted directory. This is intended to be used when you leave Atree to do some other work with other programs and change the composition of directories or the attributes of one or more files. This option will delete the current memory list of files in the highlighted directory and reread directly from the disk in order to achieve an exact correspondence between files in the directory and their representation in memory. Also, if you have specified a maximum depth for reads (see the "Set Max Depth" option in the "Tree" menu), you may end up with your last layer of directories showing in the directory display box, but any files contained in these directories will not have been read. You may use the "Reread Files" option to read only the files in these directories (subdirectories will not be read). These files will be incorporated in the list of all files in the currently displayed tree -- they will therefore be included in any subsequent use of routines in the "Sort" and "Locate" menus. (NOTE: the Configs menu, described below, has an option to set "reread" on or off for automatic use in some cases). Mark Destination: Highlighted directory becomes the target or destination directory for MOVE and COPY functions. Any function requiring a target will not work unless a MARK is set. Show Destination: In case you have forgotten which directory in which tree you have selected, this option will tell you. You will however only get an abbreviated representation of the complete destination path specification; you will be given the name of your "tree top" (what you specified in order to read this tree) and the name of the directory that is marked as the destination (There may, of course, be more than one directory with the same name in a given tree, so be careful about your assumptions). The complete destination path specification is not given for the simple reason that Atree supports up to a depth of 65536 directories, each of which can have a name up to 40 characters long -- that represents a string of 2,621,440 characters! Goto Destination: Select this and your destination directory will be displayed and highlighted in the upper left corner of the display box. Place Mark: Atree allows you to set up to three place markers. The highlighted directory is marked so that it may be subsequently returned to from any tree or directory. Goto Mark: If a place mark has been set, selecting the goto option (1, 2, or 3) corresponding to it will cause the marked directory to be displayed and highlighted in the upper left hand corner of the directory display box. Prune: Selecting this option will delete all files and sub directories in the currently highlighted directory. The highlighted directory will also be deleted. This function is like cutting a complete branch from a tree. The function may not do a complete job of pruning if for any reason files and directories cannot be found or deleted. The prune function will, in other words, prune whatever it can. NOTE: The prune function will delete even delete protected files and directories without question or warning. Therefore, the user must make sure none of the files or directories in the branch to be pruned are wanted. For best results, the user should be sure that the memory copy of the tree's branch being pruned corresponds exactly to what is on the disk. Graft: This function copies what it can of the branch from the currently highlighted directory to the currently marked destination. The graft function can be used to copy an entire disk to a blank disk or to ajoin an entire tree to a marked destination in another tree or in the same tree. Tagged files: A requester will display the total bytes in all files tagged in the currently highlighted directory. Untag all files: Any files tagged in this directory will all be un-tagged. Quick path: This option allows the making of a directory "tree" consisting solely of the end directory of a complete directory path you specify. This directory is automatically made the destination directory for all subsequently selected file operations, thus overiding whatever was previously selected as the destination directory. To understand why this option is available and how it improves efficiency, suppose you were in a situation where you wanted to copy a bunch of files from the currently highlighted directory to a specific directory on a disk in df0:. One way of doing this would be to select "t" then "+" and specify your specific directory. Atree would then read in the entire tree from your directory up to the depth to which "max depth" is set. Doing this would cause Atree to then display your new tree and you would then have to set the desired directory as your destination. Then you would have to find your way back to the original tree you were in, locate the directory you previously had highlighted and then select the desired file operation. With the "Quick path" option, assuming you already have your source directory highlighted, you merely request "Quick path" and specify your path. Atree quickly reads in only the end directory you specified and marks it as the destination and leaves you in the highlighted directory. All you have to do now is select the file operation you want involving this new destination and away you go. Anytime later, you can find your way to this new tree to examine it or delete it from your system. File Menu: ------------------ Copy, Move and Delete highlighted, tagged, or all files in currently highlighted directories; choices should be obvious. Archive: Use the Configs menu (see below) to specify the path to your favorite archive utility. Then select "Archive" highlighted/tagged/all from the FILE menu. You will be presented with a requester asking you to "Enter ARC arguments:". You should enter everything here that you want to be added to your path spec for your archive utility, except the filename -- this will be added automatically by Atree. The filename added by Atree depends on whether you selected highlighted, tagged, or all. To make the above clearer with an example: Suppose you entered "dh2:utilities/arc" as your path spec in the Configs menu for your Archive selection. Suppose you now select Archive/highlighted from the FILE menu. You get the requester asking you to enter arc arguments. Suppose you enter here, "a newarc". Suppose your highlighted file name is "this_file". What will happen now is that Atree will execute the command line: dh2:utilities/arc a newarc this_file For my particular version of ARC, the above command line will create an archive file, newarc.arc, in the current (highlighted) directory (if it doesn't already exist) and then will add "this_file" to it. Selecting "tagged" or "all" instead of "highlighted" will result in the above command line being executed over and over for all appropriate files. NOTE: at present, despite what your ARC utility supports, this version of Atree will not allow you to archive files whose names contain spaces. Thus, you can archive a file named "session1", but not "session 1". Execute: Executes the highlighted file with the RUN command; a command tail is requested via a requester and is optional. Text reader, editor, word processor, IFF displayer and sector editor should be obvious, but will not function unless first specified by selecting the "Paths" option from the CONFIGS menu. If specs are made in the CONFIGS menu, the program specified will execute with the RUN command and with the highlighted file as the command tail. Tag matching: If a pattern string has been specified via the "string" option of the "locate" menu, selecting this option will cause all files in the highlighted directory which match the specified string pattern to be tagged. User's Choice: Using the "User's choice" option of the "Configs" menu, you may specify the complete path for up to five programs you may wish to execute from Atree. When you run Atree for the first time, the five subitems of this option are listed as "??? Not Defined". Before these can have any meaning, you must first define these options by selecting one of the subitems under the "User's choice" option of the "Configs" menu. NOTE: It is obvious that the user may alter a directory tree or a file in many ways without the memory copy of the tree or file list being correspondingly changed. Therefore, through the use of text editors, word processors, archive utilities, etc. your memory copy of a tree as displayed by Atree at any moment may not correspond to the disk it is supposed to represent. The user is advised to update the tree by re-reading it using the "Get (replace)" option from the TREE menu. Use the same path specification as necessary to update your displayed tree to keep it in correspondence with the disk it represents. Alternatively, if you have only changed files in a certain directory, you may highlight that directory and select "reread" from the directory menu to just reread the files in that directory. Configs Menu: -------------------- Paths: A requester allows user to specify a path leading to a text reader, editor, word processor, IFF display program, or sector editor (or of course any program specified). To use the requester set mouse pointer on selection, press left mouse button; if a specification was previously set, it will now appear in the uppermost string gadget at the top of the requester. If no specification was previously made, the uppermost string gadget will read "Enter path here". In either case, simply click on the string gadget and enter the desired path specification and press RETURN. When the corresponding selection is made via the FILE menu, the specified program will be executed with the highlighted file as the command tail. Thus, suppose you select "Text Reader" and in the string gadget you enter "dh2:utilities/blitz". When you now go to the FILE menu and select "Text Reader", Atree will execute the following command line: Run dh2:utilities/blitz <filename> where <filename> is the currently highlighted file. Selections which specify text editor, word processor, or archive utility do not execute with the RUN command. Set buffer: This is the read/write buffer for copying, moving, and grafting files -- settings above 512 or so are not too significant in terms of promoting speed, but you may set what you like. When routines are developed to use this buffer as a temporary storage area for sections of text in files being searched for specified strings, a large buffer will prove advantageous. Save: Saves the currently specified paths to text reader, editor etc. Current colors are also saved (See "Colors" option below). The file, Atree.Config, is created in the directory specified by the s: assignment. If you are a first time user of Atree, and the Atree.Config file does not exist, you will get a prompt upon running Atree telling you "object not found" -- click on "continue" and the program will proceed with its initialization. Set up your config file per the above instructions for future running. The "Save" option will also save to the config file the currently specified "maxdepth" setting -- see the "Set max depth" option of the "Tree Menu" above. NOTE: the Utils menu (see below) has options for saving and reloading the currently specified configs (colors, etc.) to and from filenames you specify. You thus have unlimited config file capability. Your default config file which will always be looked for on running Atree is "s:Atree.Config". Check sp: Can be On or Off (Checked means "on"). If check is on, a check is made for sufficiency of disk space prior to any execution of copy/move/graft functions -- these routines will be aborted via a requester if there is not enough space for the file(s) to be copied to the device. Reread: If set to "on" (checked), highlighted directories will automatically be reread after invoking the word processor, text editor, or archive utility via Atree (i.e. from the file menu). Color Change: If checked, you will be able to adjust the currently selected color (see "Colors" below on how to make adjustments). If not checked, colors cannot be adjusted (prevents accidental color changes). Colors: This option allows you to select a color so that you can subsequently change it. After selecting a color with this option, you can change the color by placing the mouse pointer over one of six small areas located at the bottom of the Atree main display screen and clicking or holding down the left mouse button. The six sensitive areas are defined below: FUNCTION SENSITIVE AREA DEFINED BY Increase RED component: The words "File size:" Decrease RED component: The word "Directory:" Increase GREEN component: The upper word "Protection:" Decrease GREEN component: The lower word "Protection:" Increase BLUE component: The upper word "Date:" Decrease BLUE component: The lower word "Date:" The current settings of all colors are saved in the Atree.Config file each time the "Save" option of the "Config" menu is selected. User's choice: You may define up to five programs to be executed with an argument string you specify each time the program is run plus the currently highlighted file. You can specify whether or not the program you select is to be executed with the "RUN" command. To make this clear, suppose you have a file searching utility called "search". Suppose the path to this file is dh2:utilities. Suppose also that there are several switches and search strings that you can specify for the search and that these switches and strings are to be specified after the executable filename (search) but before the file to be operated on (the currently highlighted file). Thus, you may wish to execute the command line: search -abcdef "search string" highlighted.filename It is precisely this pattern of execution that these "User's choices" are aimed at satisfying. To set up the above example, you would select one of the subitems from the "User's choice" option of the Configs menu. You will be presented with a requester asking you to enter a menu subitem name. The name you enter here is arbitrary and will appear subsequently in the "File" menu, "User's Choice" subitem, to serve as your reminder as to what this selection is all about. You may enter anything you like here. "Search" would be a good idea. You will then be given a requester that asks you for a path specification. Here you would give the complete path specification for your "search" program, thus "dh2:utilities/search". You will now be asked via a requester if you wish to execute this program with a "RUN" command or not. This is explained below. You may click on "YES" or "NO". Your definition of a User's choice is now done. If you now go to the "File" menu and select the "User's Choice" option subitem you just defined ("Search" in this case), you will be presented with a requester asking for arguments. You may now enter your arguments, -abcdef "search string", in this case. Now, one of two command lines will be executed: either: RUN search -abcdef "search string" highlighted.filename or: search -abcdef "search string" highlighted.filename Just which line is executed depends on what whether or not you requested to execute the program with the "RUN" command. Many programs take command line arguments as described above. These user options thus can be very useful and make your life a lot easier when using Atree. One question remains. When do you opt to use or not to use "RUN"? When you execute a program with the RUN command from within Atree, Atree immediately regains control and can continue on. When you execute a program from within Atree without the RUN command, Atree will stop dead in its tracks until you quit the program you ran (or it finishes by itself). The simple criteria to guide you is this: don't use the RUN command to execute a program that may change or alter any files that Atree itself may gain access to -- try to do otherwise and you will (probably) be visited by various GURUs. Format: Use this option to set the parameters for the format option you select from the Utils (utilities) menu (See below). You can select one of four drives (df0: thru df3:) for formatting. if ICONS is checked, formatting will result in the usual icons being placed on the formatted disk; if QUICK is checked, it will be assumed that your disk is already formatted and it will only be initialized; if FRONT is selected, the WORKBENCH screen will be brought to the front so you you can see the CLI window from which Atree was run -- this is where any status and errors from the format program will be printed. All of these settings will be saved to the Atree.Config file each time "save" is selected from the Configs menu. The "format" command file must be present in the c: directory. From dev: This option specifies the disk drive to be used as the FROM device in the DiskCopy command accessible via the DiskCopy option of the Utils menu (see below). The "DiskCopy" command file must be present in the SYSTEM: directory. To dev: This option specifies the disk drive to be used as the TO device in the DiskCopy command accessible via the DiskCopy option of Utils menu (see below). The "DiskCopy" command file must be present in the SYSTEM: directory. Locate Menu: ------------------- String: Allows definition of search string specification for searching through trees for directories, or for searching through directories for files, or for searching through all files in all directories in a tree for a matching file. The definition string may contain any of the following special meaning characters: ? matches any single character * matches zero or more occurrences of characters identical to the character preceding the "*" + matches one or more occurrences of the preceding character \? matches a question mark (?) \* matches an asterisk (*) \+ matches a plus sign (+) Here are several sample strings to help you get the idea: Example Matches a??x abyx, agtx, a56x, etc. a*x x, ax, aax, aaax, etc. a?*x ajax, abthgnfdhrrhtlo666x, etc a+x ax, aax, aaax, etc. a\?x matches only "a?x" a\*x matches only "a*x" NOTE: The search string you specify will be converted to lower case and during the search process the compare string (a directory or filename) is converted to lower case so that all searches are therefore case insensitive. Also, note that a match is considered to exist if your string is determined to match only the beginning of any compare string. Thus, "abc" will match "abcdef" and "abctuq", etc. Tree: From Top: Searches from the top of the currently displayed tree for a directory matching the pattern specified through selecting "string" above. Display moves to the found directory. The search is always made downward in the display column before moving to the next column to the right. From Here: Same as above, except the search begins with the next directory down in the same column as the highlighted directory. Directory: From Top: Searches from the top of the currently highlighted directory for a file matching the pattern string. Search stops at end of list of files belonging to the highlighted directory. Display moves to found. From Here: Same as above, except search begins with the file next down from the highlighted file. All Files: From Top: Searches all files in current tree irrespective of directory for a file matching the pattern string. Search starts at top. Display moves to found. From Here: Same as above, except search begins with next file down from the currently highlighted file. Sort Menu: ------------------ The options in this menu should be clear -- the user can sort the highlighted directory's files by name, size, or date, and can sort the entire currently selected tree's files in all of its directories by name, size, or date. Utils Menu: ------------------ Format: Formats a disk according to the parameters set via the format option in the Configs menu. This option will present a requester asking for the volume name you wish applied to the disk. This option merely executes "format" with the RUN command -- the executable file "format" must therefore be in path, usually the path to which SYSTEM: is assigned. The correct arguments for the format command (drive to be formatted, etc.) are derived from the parameter settings in the Configs menu. You have control of Atree while the formatting is taking place. The output of the format command is printed to the CLI from which Atree was executed -- if you wish to view this CLI during formatting, you may find your CLI manually, or you may select "FRONT" from the format option in the Configs menu before starting the format process -- doing so brings the WORKBENCH screen and the CLI window into view during the formatting process. DiskCopy: This option executes the normal DiskCopy command. You specify the FROM and TO disk drives using the "From dev" and "To dev" options in the Configs menu. You will be asked for the name you wish to apply to the copy and if you don't enter anything here, the name of the copy will be the same as the name of the source disk. DO NOT set the "From dev" and the "To dev" to the same drive as this will merely waste your time copying the disk to itself. Save alt config: This option allows you to save all of your currently specified configs (colors, etc.) to a directory and file of your choice. Load alt configs: This option allows you to reload a given set of configs (colors, etc.) you previously saved to a given directory and file via the "Save alt configs" option above. Iconify: This option allows the Atree screen and window to be shut down and replaced by a very small window (not really an "icon"). This small window will always appear in the upper left hand corner of the display. It may subsequently be dragged around on the display or placed behind all other screens by clicking on the Window-to-back gadget. To reactivate Atree, just click on the word "Atree" in the small window. Change Dir: This option makes the currently highlighted directory the current directory for all AmigaDos commands subsequently entered by selecting "CLI Command" from the Utils menu (see below). Suppose, for example, you wish to compile a file in the currently highlighted Atree directory. Choose "Change Dir" and the currently highlighted directory is now the current directory for AmigaDos commands. Now select "CLI Command" from the Utils menu and in the requestor type "lc filename". The file whose name is "filename" will be compiled (provided "lc" is in your path). The output of all CLI commands is directed to the CLI window from which you started Atree. If you select "Change Dir" and then select "CLI Command" and type "dir" at the requestor and then find the CLI window from which you started Atree, you will see the files/directories in the highlighted directory printed to the CLI. CLI Command: See above for explanation. Print: Atree allows you to print to your printer all or part of a tree or just a directory. The three options are: Tree long: Prints all directories and files (with file size, and date). Full pathname is printed for each directory. Only first 30 characters of filename are printed. Tree short: Prints outline format of directories and files. Directories are preceded by a number representing the depth or level of the directory in the tree. For clarity, files are preceded by a "-" instead of number. Only the first 20 characters of directory and file names are printed. When the outline reaches the 18th level, subsequent levels are "wrapped" back to the left margin of the printout and continued from there. Directory: Prints the full pathname of the current directory and then prints all files (30 characters of name only), file sizes and dates. ********************************** Keyboard operation ********************************** Most of the routines in Atree's menus may be accessed by first pressing the key corresponding to the first letter of the menu's name (thus, press the "t" key to access the routines in the "Tree" menu, or press the "f" key to access the routines in the "File" menu). This will cause Atree to go into a mode waiting for you to press another key -- the key you press next must be either the "escape" key, or one of the keys indicated to the right of the name of one of the routines available in the menu you have selected. Thus, if you press the "t" key, followed by the "+" key, you will activate the "Get (new)" routine of the "Tree" menu. After pressing the "t", you must press the "Esc" key to abort this mode. If a menu option has additional options, you must press the appropriate keys to access those options, or the escape key. Thus, pressing the "f", "c", and "h" keys in succession will activate the "copy highlighted file" option of the "File" menu. Pressing the"f", "c", and "t" keys will activate the "copy tagged files" option of the "File" menu. If you have pressed the "f" and "c" keys in succession and you wish to abort your operation, you must press the "Esc" key. If you have pressed the "t" key but have forgotten the keys associated with any of the options of the "Tree" menu, you may still see those options by using the mouse -- the menus can still be activated, although the options associated with them cannot. When a key corresponding to the first letter of the name of one of the menus is pressed, the window title bar will change and will indicate which menu's options Atree is now waiting for to be activated by a selection from the keyboard. As indicated above, press "Esc" to abort. ********************************* Future Enhancements: ********************************* The following enhancements to the program are in process and will be included in future revisions: 1. Allow user to abort copy, move, delete, prune, graft operations. 2. Allow moving and copying files with preservation of original datestamp. 3. Allow use of Atree from the Workbench. 4. Allow user to set a filespec for display, e.g. display only files with ".doc" extension, etc. 5. Develop disk sector editing routines. 6. Develop routines to allow user to do string searches of text files. 7. Set/View date routine. 8. Datestamp change for files.
