Help with program that emulate VT100 terminal

[Aacini]

Nice work Antonio!

If you need to debug you can use [url]

I have probed but there are some problem on some lines and the color should be adjusted

I have tried some years ago on ubuntu this is a snapshot of an user that developed a color adjust.

For the vt100 emulator (in real time, not file input) have you some suggestion?

The link to the US-SLURG.ANS file fail because timeout. I tried to browse the sixteencolors.net site, but it is too slow and there are not indications of the type of file shown. Could you post here the US-SLURG.ANS file? I think it is not very large.

There is a complete Ansi driver for Windows; it is called ANSICON and you may download it from this site: "ANSICON provides ANSI escape sequences for Windows console programs. It provides much the same functionality as ANSI.SYS does for MS-DOS."

EDIT: This is the direct link to the site to download ANSICON: http://adoxa.altervista.org/ansicon/

Yes, the site is slow and rotten .

Ok. Ansi files downloaded, thanks!

Several of the .ANS files use an attribute code that confuses me. As I understood it, each "ESC [ ... m" sequence set the attribute from the point it appears on cancelling the previous attribute, NOT combining the new attribute with the previous one. If this is true, then the 0 attribute: "all attributes off" is meaningless, because any way the new attribute will cancel the previous one, and the zero may be just ignored.

However, is possible that I misunderstood the way to use the "ESC [ ... m" sequence and it must combine the new attribute with the previous one, in which case the 0 attribute is useful. I need this information in order to modify my AnsiSys.exe program, because an initial zero in the attribute, like in "ESC[0;36m", cause the problem.

The MSDOS V6.22 help.com and help.hlp contains useful reference material.

I have a copy if you can't locate it.

Simply pipe the output of your program that generates ANSI escape sequences to ansisys.exe

Code: Select all

yourProgram | ansisys.bat

It works great with the brainf*** hanoi program.

Antonio,
There is an AnsiSys.exe bug that I seem to have found:

When ESC[40;37m is used then it uses the default screen colour - which is green in my case - where is should be using white.



I modified the display portion of your example batch file - people may find it easier to see how AnsiSys.exe can be used.

A modified version of "Ansi Color Table.bat"

Code: Select all

Antonio,
There is an AnsiSys.exe bug that I seem to have found:

When ESC[40;37m is used then it uses the default screen colour - which is green in my case - where is should be using white.

You are right, foxi! I fixed this problem and posted the new version of "Ansi Color Table.bat" in the same place of the original, so just delete AnsiSys.exe program, download the Batch file again and run it.

This "bug" was caused by a misinterpretation of how each one of the Ansi attributes should be processed. In the first version, each time a new attribute appear I "initialized" the attribute with zero, that means "black on black", and then insert the new attribute; this produces a black color on the unassigned attributes (foreground or background), but an unassigned attribute should mean "default color" if COLOR command was used. In the new version I keep the "previous" attribute and combine it with the new given one. However, I can't still duplicate the same colors of some images, and I think this is caused by how the "light colors" 1 and 5 attributes are combined. I can't find an exact description of how Ansi attributes must be processed and I don't like to do multiple tests.

Perhaps someone could help me to fix this problem posting some cases of attributes not correctly processed and the way they must appear. In this case, don't forget to first download the new version!

Antonio

PS - I like your modification!

[foxidrive]

I fixed this problem and posted the new version of "Ansi Color Table.bat"

It's fixed the bug I mentioned, but something broke in the highlite implementations.

The left is how my modified script appears with the new binary - and the right is how it appears with the old binary.
Note that two lines are now identical, the top line in attribute 5 and the top line in attribute 5;1



Sorry for the large images.

Yes, the way to fix this "bug" was to keep previous attribute and combine it with the new one; this means that if the new attribute does not include a certain part (where the 4 possible parts are: foreground color, background color, foreground light 1 and background light 5), then such part is preserved from previous attribute. However, the COLOR command modify the value we take as "previous attribute". If COLOR command set Light Green on Black, for example, then the "previous attribute" includes the Foreground Light part, so any text will be displayed with this attribute set even if the new attribute does not include the 1 part. Exist the 0 attribute that is defined as "Reset / Normal text", that is, when 0 attribute appear it clear any previous attribute and set the current one as 7 (White on Black).

Note that previous description REFERS TO THE WAY I WRITEN MY ANSISYS.EXE PROGRAM, because I couldn't find a precise description on the way these details must be managed! I think that the only way to clear this point is running a test program in any computer that have a reliable Ansi driver (like an old MS-DOS machine) and take the output as base. The Batch file below, that is your modified version with just one section more, may serve for this purpose. If anyone have a computer with an Ansi driver, I'll appreciate it if you may run this program and post an image of the output screen.

I think I got this right: Left is the original AnsiSys.exe Right is the new AnsiSys.exe


I had to modify the batch file to run in Win 98SE

If anyone have a computer with an Ansi driver, I'll appreciate it if you may run this program and post an image of the output screen.

It occurs to me that you might want to see what a plain ANSI.SYS driver does with the code - here is the plain batch version:

This is exactly the information I need, excepting for one detail: How the plain ANSI.SYS driver show previous image WHEN COLOR COMMAND HAD SET A LIGHT FOREGROUND COLOR?

Code: Select all

echo Set (default) screen colors to Light Green on Black (COLOR 0A)
color 0A
echo/

Please, include previous lines in the plain batch version (below CLS command) and run it again with the plain ANSI.SYS driver...

Antonio

PS - Please, post an image a little bit larger...

[foxidrive]

I would but Win98 and Dos don't have the color command.

[foxidrive]

The nearest I can do is to use another ansi sequence to set the green-on-black colour at the start - is that ok?

[Aacini]

I would but Win98 and Dos don't have the color command.

This means that my AnsiSys.exe driver may show attributes when COLOR command changed the default colors IN ANY WAY I WISH because none can tell my that my colors are wrong! "Wrong when compared vs. what?"

Perhaps we could set a standard right now. What do you think that should be the right way? Preserve on not preserve the previous Foregroung Light color (1) and Background Light color (5) attributes when a new attribute is set and it does not include 1 or 5?

Knows anybody how AnsiCon.sys program manage this point?

Antonio
