- T v2.20 - A Tiny Editor
- =======================
-
- Changes From Previous Version
- -----------------------------
- The major change between the previous version (v2.00) and this version
- (v2.20) is the support for editing lines longer than 256 characters; lines
- may now be up to 65,528 characters long. This is particularly useful with
- OS/2, where lines in CONFIG.SYS are often longer than 256 characters. Also
- please note there is a change to the operation of the MARK RIGHT and MARK
- LEFT functions and there are a few changes in the custom definition file
- syntax, to provide improved readability and consistency.
-
- Introduction
- ------------
- There are times even in today's world of multi-megabyte personal computers
- when a quick, simple and small text editor is of benefit. With a .EXE file
- of less than 10,000 bytes T is designed to fit that role. For the DOS user
- trying to cram more and more into 640K the advantages of small size are
- obvious, for the OS/2 user the speed and ability to run when even
- Presentation Manager is unavailable may prove just as useful.
-
- This document gives a very brief introduction to the Tiny Editor. Refer to
- the full documentation in T.DOC for all the details of the editor's commands
- and keyboard functions. T.DOC also describes how T may be customised to
- suit individual preferences for things like screen colours and keyboard
- layouts.
-
- Installation
- ------------
- The only file required to use T is the single executable: T.EXE for DOS or
- T2.EXE for OS/2. This should be placed in the current directory or in a
- subdirectory listed in the PATH.
-
- The help file THELP.HLP gives a summary of the editor's features. It may be
- useful to have this available the first few times T is used. Pressing the
- F1 help key will attempt to load and show this help file.
-
- Simple Editing
- --------------
- To start the editor just enter the command T from a DOS prompt or T2 from an
- OS/2 prompt. This command can be followed by any number of filenames which
- will be loaded ready for editing. If no filenames are given a new empty
- file will be created.
-
- The cursor starts on the editor's command line (the third line up from the
- bottom). Any valid T command may be entered on the command line and is
- executed when the Enter key is pressed. Some valid commands include:
-
- EDIT - To load a new file into the editor.
- FILE - To write the currently displayed file back to disk.
- PRINT - To print the currently displayed file.
- DOS - To run a DOS or OS/2 command.
-
- The cursor can be moved between the command line and the file's data area by
- pressing the Esc key. In the data area it can be moved anywhere between the
- "Top of File" and "End of File" markers. At any point new text can be
- entered or the existing text changed. To add a new line press Ctrl-Enter
- and to delete a line press Ctrl-Backspace.
-
-
- One or more lines can be marked by pressing Alt-L on the first and last
- lines of the block to be marked. Marked lines can be moved by pressing
- Alt-M, copied with Alt-C or deleted with Alt-D.
-
- The current line can be repeated with Alt-R, split at the cursor position
- with Alt-S and joined with the following line with Alt-J.
-
- If more than one file is being edited at once the "ring" of files can be
- cycled around by pressing F10 or F11. Editing several files at once is
- particularly useful in conjunction with marked lines, as lines from one file
- can be moved or copied into a different file.
-
- When all the required changes have been made the file can be written back to
- disk by pressing F2 and quitted with F3. Alternatively F4 will perform both
- these actions in one go. If you decide to abandon all the changes made just
- press F3 and answer the question "Throw away changes?" with a "y".
-
- To search for a particular piece of text, switch onto the command line and
- enter the command: /text
-
- T will search from the current cursor position forwards to find the next
- occurrence of the "text". Normally T requires an exact-case match (i.e. it
- would not find TEXT or even Text); to force an any-case match add a "c"
- option to the command like this: /text/c
-
- To do a search and replace, again switch onto the command line and this time
- use the command: c/this/that
-
- This will find the next occurrence of "this" and ask a question
- "Yes/No/Go/Last/Quit?". Respond with a Y, N, G, L or Q as required:
-
- Yes - to change "this" to "that" and search for the next "this".
- No - to not make the change, but continue the search for the next
- "this".
- Go - to make this change and all subsequent changes up to the end of
- the file without further prompting.
- Last - to make this change and to stop searching.
- Quit - to not make this change and to stop searching.
-
- To make all the changes straightaway, without prompting add the "*" option
- to the change command like so: c/this/that/*
-
- Customisation
- -------------
- T may be customised to change the colours, keyboard assignments and one or
- two other settings. Take a look at the TKEYS.DEF file which describes the
- standard configuration. If you want to alter it, make a copy of TKEYS.DEF
- and edit it to reflect your required changes. Then run the TKEY.EXE
- customiser program to update the editor, like this:
-
- TKEY TKEYS.DEF T.EXE
