ETDE the Esperanto edition of the Thomson-Davis Editor version 1.9 june 1992 Frank Davis Adapted for Esperanto by Pierre Jelenc 1992-6-1 Internet: pcj1@cunixf.cc.columbia.edu Compuserve: 71022,1726 Description: (Note: this version of TDE for Esperanto is called 1.9. It has the same functionality as version 2.0 of the English release. The reason for the different number is that it does not yet have prompts and messages in Esperanto. ETDE 2.0 will be the fully translated program) [P.J.] ETDE is a simple, public domain, multi-file/multi-window text editor. It is suitable for editing batch files, text files, and various computer language source code files. The only limit on the number and size of files that ETDE can handle is the amount of conventional memory. Likewise, the only limit on the number of windows is the amount of conventional memory. There is no preset maximum number of files or windows that may be open at any one time. Usage: At the command line type: ETDE [file name(s)] For example: ETDE ETDE foo.bar ETDE c:\c60\tde\main.c ETDE *.c \qc25\tde\*.h ETDE foo.bar foobar f* foo.* f??b?? If you don't enter a file name at the command line, ETDE will prompt you for a file name. If the file does not exist, ETDE starts out with an empty file with the file name you just entered. ETDE will handle files as large 465k. If you try to edit a file larger than 465k, only the first portion of the file is loaded into ETDE. With DOS 5.0, you can edit files as large as 515k if you load DOS high. ETDE will handle lines as long as 1040 characters. Only the first 1040 characters of long lines are handled - long lines are not truncated. What's new: New features in ETDE 1.9 include : DateTimeStamp = ^A ToggleSmartTabs = @Tab Recursive macros Support for Control-Break to stop recursive macros, sorting, search/replacing, and printing Dynamic left margin for writers Support for lines as long as 1040 characters Improved undo buffer management, which has room for the last 10 by 1040 lines or 130 by 80 lines Gathered all prompts into one header file to aid conversions to other languages Configuration file for function keys The first three new features in ETDE should be self-explanatory. They are common in most shareware and commercial editors. The next few features added to ETDE are mostly for user convenience. They should also be fairly self-explanatory. With the addition of a configuration file, ETDE has almost all of the major features on my to do list, so I'll call this version 2.0. This implies, for the time being, that there are no more major features planned for ETDE. So, for the next few months, please hold off sending in suggestions or improvements; however, inconvenient feature reports are always welcomed. If by accident you forget to put a diskette in a floppy drive and try to save a file on that diskette or if you forget to turn on the printer before printing a block or file, a critical error occurs. That kind of error is the infamous Abort, Retry, Ignore thing. A routine was written to give some information on the kind and the location of those errors when they occur. The ETDE critical error handler gives you all kinds of info and then prompts you for a response. The timeout for critical errors varies quite a bit. Some timeouts may take a couple of minutes. When I "work" at the USDA, I often need to create or massage formatted data files. Also, a lot of engineers and scientists at the USDA program in FORTRAN and the source code needs to be in a certain format. When working with those types of files, it is really useful to have a ruler that explicitly shows which column the cursor is in. The new ruler in ETDE shows margins, column numbers, and a column pointer. Another useful feature is a simple macro recording and play-back. To use it, press the Record key, then a key to which the macro will be assigned. Then press the keys to be recorded. Finish with the macro Record key again. Pressing the key to which a macro has been assigned will replay the assigned macro as though the keys were being entered at the keyboard. Any unused key may be assigned a macro. Macros can be used to enter characters that do not appear on the keyboard, such as the Esperanto accented letters. We use the ALT and SHIFT-ALT combinations for this purpose. <CR><LF> or <LF> at eol The functions that write to files were expanded to allow you to choose whether you want to write a <CR><LF> or just a <LF> at the end of line. Some programs look for just the <LF> at the eol while others want the <CR><LF> pair at the eol. ETDE has no trouble reading either style but allows you to specify the output style. You may change the style by pressing the ToggleCRLF function key or by using tdecfg to set the default. Here's a little diagram that may help explain the new functions better than I can write.

You will have two keys depressed together at the same time. The function assigned to that key combination will be executed as soon as the second key is pressed. You may release the keys in any order you choose.

Pressing the Alt + a number key on the keypad generates a character code and not a cursor movement command. FYI, the Alt+keypad is the method for entering any ASCII or Extended ASCII character into the text file. Function Keys: I tried to use some logical order when I assigned functions to the function keys. I use a 101 keyboard most of the time, so it should be easy to see the logical function grouping with it. The function keys on a 101 keyboard are placed along the top of the keyboard. Functions are arranged as follows: F1 Help F2 Save files or change attributes F3 Quit; Macros F4 Exit; load new files F5/F6 Search and replace F7/F8/F9 Windows F10/F11/F12 Margins and formatting Note: The key assignments in ETDE are quite different from those of the English version. All the ALT and SHIFT-ALT combinations have been reserved for non-English characters via macros. F1 = Instantaneous Help File Functions: #F2 = Save file Saves all changes made to file. Existing file is overwritten by the new file. It does not prompt for a new file name - automatically assumes you want to overwrite the old file. F2 = Save as If you don't want to overwrite the original file but you want to save the contents of the current file, you may save the file under a different file name. This function prompts you for a file name to save the changes (press escape to abort). @F2 = Set file attributes Change the attributes of a file. Attributes are: A = Archive, S = System, H = Hidden, R = Read-Only. You can change the attributes of a file so that read-only files can be edited. To edit a read-only file: 1) edit the file, 2) change the file attributes to archive, 3) save the changes made in the file, 4) change the file attributes back to read-only. F3 = Quit file Abandons any changes made in the file and closes or kicks the file out of the current window. If you are editing multiple files or have multiple windows, ETDE searches for any invisible files to display in the current window. If no invisible windows are found, ETDE combines windows. If this is the only file being edited, F3 quits ETDE. If you made any changes to the file, it asks you if you want to abandon them. You can create an invisible window when you load in a file over the current file. Nothing happens to the invisible file or window - you just can't see it. F4 = File (save and quit) This function is a combination of Save and Quit (#F2 & F3 above). #F4 = Edit new file To bring another file into the editor, use this function. It loads the file into the current window and previous window becomes invisible. You can even load several copies of the same file. I like this because I often need to refer back to the original unchanged file. Each time you load a file, it is treated as a different file. @F4 = Edit next file If you type mutliple file names or type wildcard characters on the command line, press this key to bring in the next file or the next matching file into the editor. You may press this key at any time. When I use this feature, I usually split the screen and load the next file into a window. This feature is useful when you need to look in several files for a piece of code or if you know that you are going to edit several files at the same time. ^F4 = Directory List List the contents of a directory or matching files. At the prompt, press enter to list all files in the current directory or enter any valid subdirectory name, file name, or wild card characters. You don't have to put a *.* at the end of a subdirectory name; the directory list function adds those wild card characters to subdirectory names as a default. A '\' is added to the end of subdirectory names in the file list. To list the files in other directories, just move the cursor to the desired subdirectory name and press enter. When you see ..\ in the directory list, the double periods represent the parent of the current directory. The .\ represents the current directory. You may move up and down the directory tree by selecting the parent or childrens of the current directory. Macros: @F3 = Macro record This key toggles macro record off and on. A flashing "Recording" is displayed in the lite bar, so it shouldn't be too difficult to tell when record is on. This function assigns a keystroke or a series of keystrokes to an unused function key. There is room for 1024 keystrokes in the macro buffer. There are no restrictions on the length of a single macro. If you want, you may define one macro that contains 1024 keystrokes. When ETDE terminates, all macros definitions disappear. Macro definitions are temporary. If you want to reuse macros that are defined during an editing session, they need to be saved before you exit ETDE. Use the load macro command to bring in a previously saved macro file. For those who want to permanently assign characters or macros to unused function keys, create your favorite macros and save them to disk. Then, use tdecfg, option 5, to permanently save the macro file in ETDE. Your favorite macros will be available anytime you use ETDE. ^F3 = Save macro file Saves all macro definitions to a file. ETDE prompts for the macro file name. #F3 = Load macro file Prompts for a search pattern or file name. I can never remember macro file or path names, so this function uses a file pick list. ^ESC = Clear macros Resets or clears all macros. Find and Search/Replace: @F7 = Toggle search case Most of the time I don't care about matching the case of the search pattern. The default in ETDE is to ignore search case. If you want to consider the search case, press this key to toggle the case flag. The state of the flag is displayed, in English, in the lite bar at the bottom of the screen. You can toggle the case of the search flag at any time, even after you define the search pattern. #F5 = find forward To define the search pattern, use this function. It prompts you for the search pattern. The pattern is defined (even across files) until changed. #F6 = find backward Same as find forward except search backward in file. F5 = Repeat find forward Once the search pattern has been defined (Shift F5 or Shift F6), you can press this key at any time in any file to find the next occurrence of pattern. I decided to use two sets of functions to perform searches. Once I found a pattern, I might do some editing and then find the next occurrence. I hate to define the search pattern over and over or set the search direction over and over. This function does a wrap search - when it reaches the eof it starts over at the beginning of the file. F6 = Repeat find backward Like repeat find forward, you can press this key at anytime once the search pattern has been defined. @F5 = Repeat find forward2 Like F5 except the cursor is not repositioned to the middle of the screen. @F6 = Repeat find backward2 Like F6 except the cursor is not repositioned to the middle of the screen. ^F5 = Search/Replace forward This function prompts you for the search pattern and the replacement text. If you want to match the search case, remember to toggle the search flag (which can be done at any time). You can either do prompt or no prompt replacing. Regardless of prompt or noprompt replacing, this function actually moves the cursor to the pattern and displays it on the screen and replaces the text. If you are using ETDE on a slow machine, you can see the search/replace taking place. I implemented the function this way because I just like to see what the search/replace function is doing. ^F6 = Search/Replace backward Same as search/replace forward except backwards. Window Functions: #F7 = Split window vertically Splits the screen at the current cursor location. The current file is displayed in multiple windows. Changes to a file are echoed in all windows opened to the same copy of that file. You can also see any marked blocks in the same copy of the file in different windows. There has to be at least 15 columns in any window, so the number of visible windows is limited by the display screen. ^F8 = Split window horizontally Splits the screen at the current cursor location. There has to be at least 1 text line in any window, so the number of visible windows is limited by the display screen. #F9 = Resize window Sometimes there is a need to concentrate on the contents of one window. Use the up and down arrow keys to adjust the current window to desired size. Changing the size of the top window is not allowed. ^F9 = Zoom window Makes the current window fill the whole screen. All windows except the current window become invisible. F8 = Next window If more than one window is displayed, you can press one key to move to the next window. F7 = Previous window Move to previous window - opposite of next window. F9 = Next Hidden Window Displays "hidden" or "invisible" windows in the same place as the current window. The current window then becomes invisible. Block Commands: Block operations can be done within or between files. Operations on line blocks that move text are carried out on the line immediately below the cursor. Operations on box or stream blocks that move text begin at the column of the cursor. ^B - Mark Box Block This key is used to mark both the beginning and ending corner of a box block. Press ^B to mark the beginning line/column. ^L - Mark Line Block This key is similar to the operation of the box block, but entire lines are marked. ^S - Mark Stream Block All the text between the beginning and ending column, sorta like a stream of characters, is marked. ^U - Unmark Block If you make a booboo when marking blocks, press ^U to unmark the block and start over. After certain block operations, the block may remain marked - just press ^U to unmark it. ^X - Group Delete block Sorta self explanatory. This function deletes the text in the marked block. ^M - Move block Move the cursor to the desired location and press ^M to move the marked block. In line mode, the text is moved to the line immediately below the cursor. In box and stream mode, the block is moved to the column of the cursor. ^C - Copy block With line blocks, the block is copied to the line below the cursor. With box and stream blocks, the block is copied beginning at the column of the cursor. If you try to copy a Line block within itself, the block copy starts at the first line immediately after the marked block. ^K - Kopy block Same as copy block except block stays marked. Sorta like a poor man's cut-and-paste buffer. ^O - Overlay block You can only overlay Box blocks. The original block stays marked after the operation. ^W - Fill box block Fills the marked Box block with character. This function is useful for filling in a column of periods for tables and such. ^N - Number box block ETDE prompts you for the starting number, the increment, and whether to left or right justify the numbers. ETDE only handles integers - no floating point numbers are allowed. I felt that there were too many things involved in real numbers, eg. number of significant places to left of decimal, to right of decimal, exponents, engineering form, scientific form, etc.... If you want real numbers, just use a combination of the number box and fill box functions. Use the fill box function to make a column of decimals and the number box function to fill in the left and right side of the decimal. ^P - Print block Prints the block to the PRN device. I haven't tried redirecting the PRN, but it should work. This function prompts for block or file to print. Press Control-Break to stop printing. ^S - Sort box block Lines are sorted, ascending or descending, using the contents of the box block as the sort keys. The Ignore/Match toggle determines whether case of the keys is significant. To sort multiple columns, sort the least significant column first. ^F - Write block to file Writes the marked block to a file. ETDE prompts for the file name. ^E - Block expand tabs Expands the tabs in the marked block, which must be a LINE block, using the current tab setting. ^T - Block trim trailing Trims trailing space, if any, at the end of each line in a LINE block. @< - Block upper case Convert all lower case characters in the block to upper case. @> - Block lower case Convert all upper case characters in the block to lower case. @? - Block strip high bit Strip the high bit off all characters in the block. This function is useful when editing files produced by WordStar. Word Processing Commands: ^_ - toggle word wrap Toggle word wrap between off, Fixed Wrap, and Dynamic Wrap. In Fixed Wrap mode, the left margin is explicitly determined by the left margin setting. In Dynamic Wrap mode, the left margin is determined by the indentation of the current line. If the cursor is somewhere in the line, words are pushed to the next line. In ETDE, other than margins, word wrap and format paragraph or format text have nothing to do with each other. Word wrap is used to push characters or the cursor to the next line when the right margin is violated. Format paragraph and format text can be used at any time - they do not depend on the state of the WordWrap flag. ^F10- Set Left margin May be set to any column equal to or greater than 1 and less than the right margin. ^F12- Set Right margin May be set to any column greater than the left margin and less than the maximum line length or 1040. ^F11- Set Paragraph margin The paragraph margin may be set to any column less than the right margin. F11- format paragraph Text is formatted from the beginning of the paragraph according to the current left, right, and paragraph margins. If the cursor is not on the beginning line of a paragraph, ETDE searches for start of the paragraph and formatting starts there. The entire paragraph is formatted according to the margins. F12- Format Text Text is formatted from the cursor onward. This function does not search for the beginning of the paragraph to start the format. #F10- Left justify Beginning of current line is adjusted to start at left margin #F12- Right justify End of current line is adjusted so it ends at the right margin #F11 - Center justify Current line is centered between the left and right margins. Other keys: Enter Insert a newline at the cursor. If the cursor is in the middle of a line, the line is split at the cursor. Indentation is matched if the editor is in the Indent mode. #Enter Move the cursor down a line. The cursor is placed on the first non-blank character in the next line. No lines are added to the file. ^Enter Move the cursor down a line. The cursor is placed on column 1 in the next line. No lines are added to the file. Up (arrow) Move cursor up. Down (arrow) Move cursor down. Left (arrow) Move cursor left. Right (arrow) Move cursor right. Home Toggles between the first non-blank character and column zero. End Move cursor to the end of line character. Page Up Move cursor up one page. Page Down Move cursor down one page. ^Right Move cursor one word right. ^Left Move cursor one word left. @ Right Pan the screen one character to the right. @ Left Pan the screen one character to the left. ^Home Move cursor to first line on screen. ^End Move cursor to last line on screen. ^Page Up Move cursor to first page in file. ^Page Down Move cursor to last page in file. ^G Move to line number. ETDE prompts for line number. Press Escape to abort. Center The cursor is moved to the center of the current window. ^Center The line the cursor is on is moved to the center of the current window. Grey - on key pad @ Up Scroll window up with cursor staying on same line in file. Grey + on key pad ^ Down Scroll window down with cursor staying on same line in file. ^Grey - (grey - on keypad) Cursor stays on same line on the screen as the file scrolls up. ^Grey + (grey + on keypad) Cursor stays on same line on the screen as the file scrolls down. ^# Left Horizontal page left. ^# Right Horizontal page right. ESC - undo line Get back the original unchanged line. When cursor is moved off a line, all changes to the file are made and there is no way to get back the contents of a line. Del Delete the character, if any, under the cursor. ^Del Delete the characters in the file as if they were a stream. Lines will be joined at the cursor and eventually every character in the file may be deleted. Backspace Delete the character to the left of the cursor and move left. If the cursor is on the first column of a line, the current line is joined with the line above. If in indent mode and the cursor is on the first non-blank character, ETDE matches the indentation of the previous line(s). Tab If in insert mode, insert the appropriate number of spaces for a tab and move the cursor left. If in overwrite mode, just move the cursor left w/o inserting text. Ins Toggle between insert and overwrite mode. ^I Toggle between indent and no indent mode. In indent mode, ETDE searches for the first non-blank character on previous lines and places the cursor on that column when a carriage return is pressed. When backspacing in indent mode, ETDE lines up the indentation with the first non-blank character of the previous line(s). @F12 - Toggle ruler Toggle display of ruler in all visible windows. ^Q Duplicates the current line. @ Backspace Deletes the text from the cursor to the end of line. ^D Deletes current line, cursor does not move. ^Y Undelete the most recently deleted line. The undelete buffer has room for 10k of deleted text. If more than 10k of text is deleted, the oldest line(s) are pushed out before the new one is added. You may press ^U repeatedly to undelete all lines in the buffer. Deleted lines from line delete, delete to end of line, word delete, join line, and backspace are stored in the undelete buffer. ^ Enter Add a blank line below cursor. ^\ Split line at column of cursor. If in indent mode, the split line is autoindented. ^J Join the current line with the line below. ^Tab Set tabs. ^] Parenthesis Balance. ^Z Toggle writing Control Z at the end of file. Some programs may misbehave if a Control Z is not at the end. @1 - @3 Set a file marker. Each file may have up to 3 markers. #@1 - #@3 (Shift+Alt+1 thru Shift+Alt+3) Goto a previously defined file marker. ^A Writes the current system date and time at the column of the cursor. Toggles: F10 Toggle cursor sync. Only cursor movement commands are synced. Commands that change text are not synced. @F11 Toggle eol display. A special character is diplayed in the column of the actual new line. @F9 Toggle writing <CR><LF> or <LF> at end of line. ETDE will read a text file with lines that end in either method; however, you may want to write the file in a different method. I think *nix systems only want a <LF> of the end of line. @F10 Toggle trimming trailing space at the end of line. A 'T' is displayed in the bottom right of the mode line to indicate trailing space is trimmed. @Tab Toggle smart tab mode. Smart tab positions are determined by looking for the first, previous, non-blank line above the cursor and then positioning the cursor at the begining of the next word. It's useful for building tables and formatted data files.
