NOTE: This is a subset of Miguel Garcia's TE editor, this build is for I8080 with ANSI terminal. For complete support goto www.floppysoftware.es
About the Makefile. I am using vcpm, a virtual cpm tool written in java. This can be obtained at https://github.com/durgadas311/cpnet-z80/tree/master/tools. Best to get the entire repo, its small, and extract the tools to your system.
I have made this repo public with Miguel's permission with thanks to him.
v1.73 / 20 Nov 2021 for CP/M
(c) 2015-2021 Miguel Garcia / FloppySoftware
The te
text editor is small, humble and useful.
It edits the full text in memory, so your system must leave enough
free TPA for the text, after te
is loaded and running.
It's screen oriented, and can be easily adapted to a lot of computers.
It's written in the C language, and there are ports for various operating systems: CP/M, DOS, Windows and GNU/Linux.
I use MESCC to compile it for CP/M and the Z80 cpu.
It's simple (for the PCW adaptation; see below for the name of the rest of available adaptations):
te_pcw [filename]
Examples:
te_pcw - To start an empty document.
te_pcw todo.txt - To edit the document 'todo.txt'.
You should rename the adaptation of your choice to simply te
, because
some CCP implementations (including the standard from CP/M), do not like
the character _
in filenames.
Depending of the te
adaptation, you could see a layout similar to:
te: TODO.TXT --- | Lin:0012/0029/0512 Col:08/76 Len:07
!.......!.......!.......!.......!.......!.......!.......!.......!...
1|This is my TO-DO list for today:
2| - Wake up.
3| - Make coffee.
4| - Have a shower.
5| - Get dressed.
6| - Go work and:
7| 1. Revise email.
8| 2. Call Peter.
9| 3. Meet the boss.
10| 4. Plan tomorrow.
11| - Have lunch with Sarah.

------------------------------------------------------------------------
ESC = menu
On the first screen line, you will see something like:
te: TODO.TXT - The file name of the document your are editing.
And something like:
--- | Lin:0015/0042/0512 Col:32/90 Len:36
The very first field, can have one of the following values:
--- Means the clipboard is empty.
CLP Means the clipboard has data.
The numbers following 'Lin' are:
0015 - The line number you are editing right now.
0042 - The current total number of lines.
0512 - The maximum number of lines.
The numbers following 'Col' are:
32 - The column number on which you are.
90 - The number of screen columns.
And, finally, the number following 'Len' is:
36 - The length of the current line.
On the last screen line, you will see program messages and questions.
You can enter to the menu, by pressing the ESCAPE
key, as shown
in the messages line:
ESC = menu
Note that the exact name of your ESCAPE
key may differ, depending of
the program configuration.
The options are:
New - To start a new document
Open - To open a document
Save - To save the current document
save As - To save the current document under another filename.
Insert - To insert a text file into the current position.
Help - To show the help screen.
aBout te - To show some te information.
eXit te - To quit the program.
You can select an option by pressing the character in uppercase.
To leave the menu, you must press ESCAPE
.
If you select one of the options New
, Open
or eXit
, and there are
any changes that are not saved yet, te will ask you for confirmation
before proceed.
If you start a new document, the Save
option will redirect to you to
the save As
option.
The help screen will show the keyboard configuration (or key bindings if you prefer), which depends of the program configuration.
For example, in the case of TE_WS100 (25x80 VT100 and WordStar keys) you could see something like this:
Up ^E | Down ^X | Indent ^I
Left ^S | Right ^D | NewLine ^M
Begin ^QS | End ^QD | Escape ^[
Top ^QR | Bottom ^QC | Macro ^QM
PgUp ^C | PgDown ^R |
WordLeft ^A | WordRight ^F |
DelLeft ^H | DelRight ^G |
BlockStart ^KB | BlockEnd ^KK | BlockUnset ^KU
Cut ^Y | Copy ^O | Paste ^W
Delete ^KY | ClearClip ^T |
Find ^QF | FindNext ^L | GoLine ^J
The clipboard contents is not cleared after file operations (new, open, save...). That makes possible to share text between files.
But it's a good practice to clear the clipboard when you don't need it anymore, to free some memory.
As you can see in the help screen of example, there are some key bindings to perform actions when you are editing the file.
The exact keys you must press to do an action, depend on the configuration you are running, but the meanings are the same:
- Up, Down, Left, Right: to move the cursor one character at a time.
- Begin, End: to move the cursor to the begin or the end of the current line.
- Top, Bottom: to move the cursor to the begin or the end of the current file.
- PgUp, PgDown: to move the cursor to the previous or next page.
- WordLeft, WordRight: to move the cursor to the previous or next word.
- DelLeft, DelRight: to delete the previous or next character.
- Find, FindNext: to find a string or repeat the search.
- GoLine: to go to a line number.
- BlockStart: to mark the start of a block of lines.
- BlockEnd: to mark the end of a block of lines.
- BlockUnset: to unselect a block of lines.
- Cut, Copy, Paste, Delete: to cut, copy, paste or delete a line or block of lines.
- ClearClip: to clear the clipboard data.
- Macro: to run a macro.
- Indent: to insert spaces as indentation. Same as Tab.
- NewLine: to insert a break or empty line. Same as Cr, Enter, Intro or Return.
- Escape: to exit the menu or cancel an action. Same as Esc.
Take into account that some actions could not be available in all te adaptations to save memory space. These actions are: WordLeft, WordRight, Find, FindNext, GoLine, BlockStart, BlockEnd, BlockUnset and Macro.
If you miss one or more of the mentioned actions, you can edit the exact file of the te adaptation and recompile it to include them.
If the text editor is configured with the C language type auto-completion option enabled, the input of some characters will cause the automatic input of some other:
[ --> ]
{ --> }
( --> )
" --> "
' --> '
/* --> */
The text editor supports automatic indentation of lines, according to the indentation of the previous one.
The indentation is done by inserting the same number of spaces of the previous line - ie:
This paragraph is
indented, according to
the first line.
More indentation
here.
The text editor supports automatic lists, when the first non blank character of the previous line is one of the "bullets" according to the configuration.
As automatic indentation is supported, automatic multi level lists are possible - ie:
- Item #1
- Item #2
* Item #2a
* Item #2b
> Item #2b-1
> Item #2b-2
- Item #3
Macros are a powerful way to perform repetitive tasks at editing level.
For example, you could create a macro with your signature to include it in every letter you write.
Or, being a programmer, you could create a gdoc block macro to document your own C functions.
Macros are not affected by default by auto-completion, auto-indentation or lists.
Each time you want to run a macro, just press the corresponding key for the Macro action, enter the filename you choose when you saved it to disk, and press the key for the NewLine action. That's all.
The default filetype for macro files is ".M".
The filetype is only required when it's different. So, if you have
saved a macro file as JOIN.M
, you could just enter JOIN
:
JOIN.M you could enter JOIN.M or just JOIN
JOIN.MAC you must enter JOIN.MAC
There are some special symbols you can use in your macros:
{# comment} comments, they are ignored
{Up} {Down} {Left} {Right} move the cursor one character at a time
{Begin} {End} go to the begin / end of the current line
{Top} {Bottom} go to the begin / end of the current file
{NewLine} insert a break or empty line
{Indent} insert spaces as indentation
{DelLeft} {DelRight} delete the character at the left / right
{Cut} {Copy} {Delete} operation over a line or block of lines
{Paste} paste the clipboard contents
{ClearClip} clear the clipboard data
{BlockStart} {BlockEnd} mark the start / end of a block of lines
{FileName} insert the current filename
{AutoIndent} enable / disable automatic indentation
{AutoList} enable / disable automatic list
The symbol names are case insensitive - ie: {ClearClip}
and {clearclip}
are the same.
Additionally, you can repeat a symbol as in:
{up:12}
Auto indentation or auto list can be enabled by just using the symbol
name or setting a repeat number of 1
:
{AutoList}
{AutoList:1}
They can be disabled setting a repeat number of 0
:
{AutoIndent:0}
Take into account that line endings in the macro are not translated
to NewLine actions. Use {NewLine}
for that.
If you need to insert the {
or }
characters in the text of the
macro, just write them as \{
and \}
.
For example, a macro to insert a banner at the top of the document, could be written as:
{# this is a macro example}
{top}{newline}{up}
=============={newline}
FloppySoftware{newline}
=============={newline}
Some macro files are included as examples:
HEADER.M Above example.
JOINUP.M Join current line with the previous one.
JOINDOWN.M Join current line with the next one.
There are some macros for the C language:
CFILE.M File documentation block for GDOC.
CFUN.M Function documentation block for GDOC.
CDO.M Snippet for "do / while".
CFOR.M Snippet for "for".
CIF.M Snippet for "if".
CIFELSE.M Snippet for "if / else".
CSWITCH.M Snippet for "switch".
CWHILE.M Snippet for "while".
Each time a file is saved, te does a backup of the previous file contents if it exists.
It is renamed as te.bkp
.
The program adaptation is done by editing a small source code file.
In this file, you must specify some configuration values according to your preferences and / or system, and complete a few C language functions to clear the screen, etc.
As there are some adaptations already done, it's possible that your machine is already included between them.
If not, don't worry, you can start from a similar adaptation.
See the source code files for more information.
Current CP/M adaptations are:
te_pcw
: Amstrad PCW and CP/M Plus (31x90 VT52 like terminal).te_cpc3
: Amstrad CPC and CP/M Plus (24x80 VT52 like terminal).te_spec

: SAM Coupe and Pro-Dos (24x80 VT52 like terminal).
Adaptations for other OS are (they are not distributed yet):
- Windows 32 bit (25x80), compiled with Pelles C and its 'conio.h' library.
- DOS (25x80), compiled with Turbo C, and its 'conio.h' library.
- GNU/Linux (24x80), compiled with GCC and ncurses.
The TECF
configuration tool is supplied in order to adjust
some TE
generic options to your taste, if needed (its use
is totally optional):
TECF v1.21 / 13 Nov 2021 - (c) 2021 Miguel Garcia / FloppySoftware
TE configuration tool.
Usage:
tecf action arguments...
Actions:
patch COM file from CF file:
patch [[filename[.COM]] [filename[.CF]]]
dump CF values from COM file:
dump [filename[.COM]] [> filename.CF]
print key codes:
key
You can configure TE by using the patch
action - ie:
tecf patch te.com myconf.cf
The standard file types (COM
, CF
) and filename (TE
) are optionals,
so you could patch te.com
with te.cf
just with the command:
tecf patch
Take into account that the disk has to be enough space for a temporary file with the exact size as TE.
You can see the current configuration of TE by using
the dump
action - ie:
tecf dump
To save the configuration in a file just add a redirection (a tecf
feature thanks to MESCC
):
tecf dump > myconf.cf
The standard file type (COM
) and filename (TE
) are optionals.
If you don't know the character/s assigned to a key, the key
action
will help you:
tecf key
For example:
TECF v1.21 / 13 Nov 2021 - (c) 2021 Miguel Garcia / FloppySoftware
TE configuration tool.
Press any key to get its code/s (SPACE = exit):

A CF
configuration file is just a text file with some key / value
pairs, in a very similar way of INI
and conf
files in other
systems.
Just a few rules:
- comments start with the
#
character. - empty lines are ignored.
- strings can be surrounded by the
"
character.
See my CF
and CF READER
projects for more information.
Each adaptation is supplied and patched with an initial configuration file that includes key bindings, etc.
You should create your own configuration files if needed.
The current supported options are the following (see TE.CF
):

The text editor is supplied with TETX
a text tool in order to help you to process
text files.
TETX v1.01 / 20 Nov 2021 - (c) 2021 Miguel Garcia / FloppySoftware
TE text tool.
Usage:
tetx [-options...] [fname...] [> fname]
Options:
-e Skip empty lines.
-l Convert to lowercase.
-n Print line numbers.
-t[N] Convert tab to spaces (default = 4).
-u Convert to uppercase.
-wN Max. width of lines (32..255).
-s Trim spaces on the right.
Examples:
tetx -ne mydoc.txt
tetx -t4u -n letter1.txt letter2.txt > letters.txt
The -n
option will print the line number before each line:
25 This is a text line,
26 and this is another one.
The -t
option will convert tab characters to spaces,
there is a tab each N columns:
+ + + + + + + +
This line does not have a tab.
But this one has one.
And this one has two.
A tab here.
The -w
option will split lines longer than N characters:
This is a line longer than 32 characters.
The command tetx -w32
will process the line as:
This is a line longer than 32 ch
aracters.
You can combine options as -w32nu
or -w32n -u
:
1 THIS IS A TEXT WITH LINE N
2 UMBERS. IT HAS A MAXIMUM W
3 IDTH OF 32 CHARACTERS AND
4 IT HAS BEEN CONVERTED TO U
5 PPERCASE.
The output is written to stdout
(the console). So, you
must use output redirection to a file, in order to save
the result:
tetx -w32nu draft.txt > final.txt
You can omit the input filename, in order to read the input
from stdin
(the console):
tetx -w32nu > letter.txt
Or you can combine two or more files (-
means stdin
):
tetx -w32nu header.txt body.txt footer.txt > letter.txt
tetx -w32nu header.txt - footer.txt > letter.txt
This program is freeware, and it's licensed under the GNU GPL license.
See the file copying.txt
for more details.
Of course, this text file has been created and edited with te.
