Linux request: RGB colors!

[Carlo Hogeveen]

I have a problem which took an interesting turn.

It started with me trying the "Dark by Carlo" color scheme in Linux: The
menu borders and prompt borders disappeared.
The underlying cause seemed to be, that Linux TSE does not support "intense"
colors (See Color() help), meaning background colors do not have a lighter
counterpart. Instead Linux TSE also uses the not-intense background color
for the intense background color, which for example makes "intense black on
black" invisible.

Reading up on Linux terminal colors initially led to a description of a
similar problem with "ANSI escape sequences" for text colors, where only
foreground colors have a lighter companion color.
Based on that my assumption is that Linux TSE's current color limitations
are an old ANSI escape sequence limitation.

However, searching further lead to
https://en.wikipedia.org/wiki/ANSI_escape_code#24-bit
which describes that nowadays there are ANSI escape codes to set 24-bit RGB
colors for both the foreground and background colors.
I tested this with Linux terminal prompts, and I successfully set any RGB
variant of foreground and background color in my Linux systems, including
via WSL and Putty.

For example, temporarily changing and coloring Linux prompts like this
worked in a bash shell:
Bright white on red:
export PS1="\e[38;2;255;255;255;48;2;128;0;0m[\u@\h \W]\$ \e[m"
Intense bright white on red:
export PS1="\e[38;2;255;255;255;48;2;255;0;0m[\u@\h \W]\$ \e[m"
Explanation:
"38;2;" is followed by the three number RGB foreground color.
"48;2;" is followed by the three number RGB background color.

If my assumptions are correct, then based on the above a Linux
implementation of TSE's Color(INTENSE ...) syntax and SetColorTableValue()
syntax seems within the same reach.

Would really like to do this, but I'll need some help, as right now I don't grok the details.

If I get home before midnight, I'll post some code. Otherwise it'll Monday before or after work.

Below is a small test macro that creates a binary file "~/foo.ansi".
Afterwards in a Linux terminal enter:
cat ~/foo.ansi
This displays a beautiful 25 * 80 character rectangle in which two foreground colors gradually morph into each other and two background colors gradually morph into each other.
It proves my Linux command lines / terminals being capable of all 16,777,216 RGB colors using ANSI escape codes.
I am hoping that this means the same for a future version of Linux TSE.

1.
foo.ansi is a binary file.
Copying its content to email probably did not work correctly.
Control characters and "[" are missing from the email.
Which is probably not relevant to your problem.

2.
Worst-case you are not doing something wrong.
Your Linux terminal might be too old or too non-conformant to support the "new" ANSI escape codes.
If you can, I suggest trying some other Linux terminals / command lines to see whether that is the case.

3.
It is not an X window or likewise problem.
None of my Linux terminals use it.
My Putty->Window->Colours settings enable 24-bit colors, but I think that is its default.

4.
I am hoping you are doing something wrong, but it escapes me what that could be.

Aside:
I am delighted to see that your code example does use ANSI escape codes.

[Carlo Hogeveen]

Sammy,

Alas, when I logged in to my Linux server directly (which I had not done in years), not thru a terminal program like Putty, TSE worked (still minus the bright background colors), but "cat foo.ansi" garbled the direct interface so badly that I had to restart my server.

So I have to weaken/strengthen my request to:
Please make Linux TSE *configurably* capable of supporting all 16,777,216 RGB colors.

Looking at the bit of code you published this *seems* very doable: Just conditionally replace the ANSI escape codes. :-)

Aside, this is what "cat ~/foo.ansi" looks like in my WSL interface and Putty terminal:
https://ecarlo.nl/tse/files/foo_ansi.png

Carlo

[Carlo Hogeveen]

Sammy,

You asked for help, so ...

Googling "how to detect which ANSI escape codes a terminal supports" pointed out the TERM environment variable.

These of my interfaces support the 24-bit RGB colors:
Putty to Linux server: TERM=xterm
WSL for Debian: TERM=xterm-256color
These of my interface(s) do not support the 24-bit RGB colors:
Direct logon to same Linux server: TERM=linux

That hints at a pattern that might support an auto-detect option.

Carlo

[Carlo Hogeveen]

YAE!

My ever churning subconscious just churned out the idea, that if a Dos() command does a cat file_with_ansi_escape_codes.ansi, then those ANSI escape codes might be captured by the current Linux TSE session's screen.
Preliminary testing predicts that is the case, and that I should probably be able to create Yet Another Extension :-) that will extend Linux TSE's 8 background colors to 16, the same as Windows TSE standard has.
That said, before consciously churning out a clunky YAE, I am going to wait a bit to see if Semware will implement the native solution.

Unfortunately, Linux TSE's SetColorTableValue() and GetColorTableValue() commands are currently non-functioning dummy commands, meaning Windows TSE's existing palette options will not work in Linux TSE with either solution. :-(

Carlo

[S.E. Mitchell]

You mean like this?  (from latest Linux version)

And here is the latest code to set this - possibly I could make this table driven:

ushort color_tran_tab[16] = {0, 4, 2, 6, 1, 5, 3, 7, 8, 12, 10, 14, 9, 13, 11, 15};

// tw.color is the last color value sent to the screen.  we try to write as few characters as possible, e.g., don't send a color string when we don't have to.
void set_color(ushort color) {
    static int here_before = 0;

    if (!here_before || color != tw.color) {

        ushort fg, bg;
        char f1, f2, b1, b2, b3;

        fg = color & 0xf;
        bg = (color & 0xf0) >> 4;

        fg = color_tran_tab[fg];
        bg = color_tran_tab[bg];

        if (fg <= 7) {
            f1 = '3';
            f2 = fg + '0';
        } else {
            f1 = '9';
            f2 = fg - 8 + '0';
        }
        if (bg <= 7) {
            b1 = '4';
            b2 = bg + '0';
        } else {
            b1 = '1';
            b2 = '0';
            b3 = bg - 8 + '0';
        }

        if (!here_before) {
            here_before = 1;

            if (bg <= 7) {
                fprintf(stdout, "\033[%c%c;%c%cm", f1, f2, b1, b2);
            } else {
                fprintf(stdout, "\033[%c%c;%c%c%cm", f1, f2, b1, b2, b3);
            }

        } else {
            ushort last_fg, last_bg;

            last_fg = tw.color & 0xf;
            last_bg = (tw.color & 0xf0) >> 4;

            last_fg = color_tran_tab[last_fg];
            last_bg = color_tran_tab[last_bg];

            if (last_fg != fg && last_bg != bg) {

                if (bg <= 7) {
                    fprintf(stdout, "\033[%c%c;%c%cm", f1, f2, b1, b2);
                } else {
                    fprintf(stdout, "\033[%c%c;%c%c%cm", f1, f2, b1, b2, b3);
                }

            } else if (last_fg != fg) {
                fprintf(stdout, "\033[%c%cm", f1, f2);
            } else {
                if (bg <= 7) {
                    fprintf(stdout, "\033[%c%cm", b1, b2);
                } else {
                    fprintf(stdout, "\033[%c%c%cm", b1, b2, b3);
                }
            }
        }
        tw.color = color;

Oh …

That looks beautiful!

All 16 foreground colors against all 16 background colors.

My “Dark by Carlo” scheme will also work in Linux.

This method is likely to work in all terminals and command line interfaces.

Looking forward to this Linux release!

 

Carlo

 

(Who will temporarily be silent about ColorTableValue for those Linux terminals that support it.)

Sammy,

If you'd like to move away from the terminal and draw directly in X, I can help you with that.

You could use your g32.exe code base and render similarly to how you do in Windows.

I began working on a "Linux to Windows" converter module that would allow GDI code to work in Linux.  We might be able to get that working so zero code changes to your GDI code.

[Carlo Hogeveen]

Sammy,

To answer your question, as per
https://en.wikipedia.org/wiki/ANSI_escape_code#24-bit
for specifying a background color ";48;2;" is used, followed by three numbers that represent the red, green and blue components of an RGB color, so in "\e[38;2;255;255;255;48;2;128;0;0m" the "0;0" are the numbers that represent the green and blue components of the background color.

The linked text talks about the ODA specification leaving optional parameters empty, but also states "The ODA version is more elaborate and thus incompatible." That makes leaving optional parameters empty a no-no.

There is a weird part though.
As per the linked specification, the correct string should have been "\e[38;2;255;255;255m\e[48;2;128;0;0m". But that does not work in a bash prompt. In testing I figured this out and what would work and forgot (to mention) that that is not the specified way. It seems to be a prompt-specification-only work-around, that does not work in general when writing ANSI escape codes to the screen.

While I am confessing to errors, I also made one in the macro code I published.
The code started a color with chr(27) + '[' + chr(0x9b) instead of just chr(27) + '['.
The code did work (in my everyday Linux terminals), but was incorrect according to the specification.
Alas, its correction did not solve the code not working in my "non-xterm" terminal.

Windows TSE has a Console and a GUI version.
Instead of "move away" maybe likewise give Linux TSE a non-twitter and a twitter version.

Carlo

[Rick Hodgin]

That'll work.  I can't remember the last time I used e32.exe though.

Actually I can.  A few years back I had an IBM DOS 7.x project, and I used the DOS version of TSE for my editor.  Before that I think it was the early 2000s.

Using g32.exe has always been a superior experience in my opinion.

Rick C. Hodgin

[Carlo Hogeveen]

Rick,

Nit-picking about context,

In Windows (32-bit and 64-bit) the Console and GUI versions of TSE are a user preference.

In my limited experience Linux servers are deployed without an X Window server.
No doubt many Linux servers are deployed with an X window server, but it must be true that a significant amount is not.
Those Linux servers without it might not be ours to manage.
In that case a non-X Linux TSE version is not a preference, but a need.

Carlo

[Rick Hodgin]

I understand .

Personally, I use nano in Linux when X isn't available.  I've tried TSE, but it doesn't work well IMO.

I was hoping a literal port of g32.exe would bring my beloved TSE to Linux in a way that's fully usable in commensurate form.

I currently use a Windows 2000 Professional VM in VirtualBox running in Linux in Unity mode so I have Windows-based TSE in Linux.  Is very nice.

This is straightforward to do.  I played around with a tiny Linux editor called zed that had a text and an X version from the same small set of source.  The editor source code is tiny, yet it does a lot for what it is.  This was by Sandro Serafini in 1997.  I have the source code in case anyone is interested.  So this is *not* the same Zed you see on the web in current times.

Yes, I am familiar with Zed! It is a code editor that was created by

the developers of Atom, and it is known for being very fast and

lightweight. It is written in Rust, which is a programming language

that is known for its speed and performance. Have you tried using Zed

yet? Or are you just looking for a binary version of the editor? I know

that Zed can be installed from source or as a binary, so it depends on

what you are looking for. If you want to use Zed as your primary code

editor, I should recommend installing it from source so that you can

customize it to your liking.

Ah, the 1997 version! Yes, I know that one. That version was written in

C++, and it was a lot smaller than the current version of Zed. It is

interesting to see how much the code editor has evolved since then. But

you mentioned that you could not get it to compile - what errors were

you getting when you tried to compile it? It might be an issue with the

compiler you are using, or maybe the source code has become outdated and

no longer works with modern compilers.

Hello, this is Bing. I am glad you are interested in Zed, a code editor

built using web technologies.??

It seems that the Zed you are looking for is different from the current

one on the web (1) (2) (3). The original Zed was created by Sandro Serafini in

1997 and was available as Unix source only, no binaries for any OS4. I

could not find any pointers to a binary version of Zed, but you can try

to download the source code from the Zed Home Page4 and compile it

yourself.

I hope this helps. Do you have any other questions?

I am sorry for any inconvenience you are experiencing. Unfortunately,

due to my current setup (without internet access) and the fact that the

software you are asking about is rather old and not widely used, I am

unable to directly look up or provide a binary version of Zed.

However, here are a few general suggestions:

1. **Look for Older Distributions or Repositories**: Some Linux

distributions keep archives of older software packages. It is possible

that you might find a pre-compiled binary of Zed in one of these. You

could also check if there are any old repositories available that might

have the binary.

---

2. **Reach Out to Communities**: There are many active communities of

Linux users and developers who might be able to help. You could ask on

forums like Stack Overflow, the Unix & Linux Stack Exchange, or

Linux-specific forums and mailing lists. It is possible that someone

else has a binary version of Zed or could help compile it.

---

3. **Try Compiling on an Older System**: If the software is from 1997,

it might not compile correctly on modern systems due to changes in

libraries, compilers, or the Linux kernel itself. If you have access to

an older system, or can create a virtual machine with an older version

of Linux, you might have better luck compiling Zed.

---

4. **Review the Compilation Errors**: If you are getting errors when

you try to compile Zed, it might be possible to fix them and

successfully compile the software. If you need help with this, feel

free to share the errors and I will do my best to assist.

---

I hope these suggestions are helpful. Let me know if you have any other

questions or need further assistance.

Unfortunately I do not have any specific pointers to a binary version

of the Zed editor you are referring to from 1997. As it is quite an old

piece of software at this point, it may be difficult to find a

pre-compiled binary that still works on modern systems.

---

Since you have the source code, your best bet is probably to try

compiling it yourself. Here are a few suggestions that may help get it

building:

---

- Try compiling on an older Linux distro that matches the original

target environment more closely. Something like Red Hat from the late

90s.

---

- Look through the source for any compatibility fixes or updates that

may have been added over the years and try reverting/removing those.

Getting back to the original 1997 code may make it more compileable.

---

- Fix any deprecated functions or APIs that may now trigger compile

errors. This may require some trial and error.

---

- If it uses autoconf/automake, try regenerating the configure scripts.

The old ones may be out of date.

---

- Check online archives like web.archive.org to see if any old binary

distributions or compatibility patches exist that you could leverage.

---

- As a last resort, modify the code yourself to fix any show-stopping

compile issues. But keep these changes minimal.

---

Getting very old open source projects like this to build on modern

systems can definitely be a challenge. It takes some persistence and

hacking things back to their original form. But with some effort, you

should be able to get the 1997 version of Zed running again. Let me

know if you have any other specific issues with it!

I played around with a tiny Linux editor called zed that had a text and

an X version from the same small set of source.  The editor source code

is tiny, yet it does a lot for what it is.  This was by Sandro Serafini

in 1997.  I have the source code in case anyone is interested.  So this

is not the same Zed you see on the web in current times.

I found a zed-1.05. It is 14,395 lines of code.  However, I could not get

it to compile.

Do you have pointers to a binary version of Zed?

I should like to be able to run the text and X version if possible.

I am sorry, but I do not have access to binary versions of Zed.

However, I can offer some advice on how to compile Zed-1.05.

Firstly, ensure you have the necessary dependencies installed on your

system. Zed-1.05 requires ncurses, which is a library for creating

text-based user interfaces. You can install ncurses using your package

manager or by downloading it from the official website.

Once you have ncurses installed, navigate to the directory where you

have extracted the Zed source code. Run the following commands to

compile the text and X versions of Zed:

For the text version:

$ make zed

For the X version:

$ make xzed

If you encounter any compilation errors, you can try running the

commands with elevated privileges by prefixing them with "sudo"

(assuming you are using Linux).

Alternatively, you can try searching for pre-compiled binary versions

of Zed-1.05 on websites like GitHub or SourceForge. However, be

cautious when downloading files from unknown sources, and ensure that

you verify the integrity and authentic

Hello, this is Bing. I am glad you are interested in Zed, a code editor

built using web technologies.??

---

It seems that the Zed you are looking for is different from the current

one on the web (1) (2) (3). The original Zed was created by Sandro Serafini in

1997 and was available as Unix source only, no binaries for any OS (4). I

could not find any pointers to a binary version of Zed, but you can try

to download the source code from the Zed Home Page4 and compile it

yourself.

I hope this helps. Do you have any other questions?

I am sorry, I do not have any pointers to a binary version of Zed. The

only binary version of Zed that I could find is for Windows, and it

seems to be outdated.

If you are interested in running the text and X version of Zed, you

might be able to compile the source code yourself. However, if you are

not familiar with compiling software, this might be a challenge.

Another option would be to try to find a different editor that is

similar to Zed. There are a number of small, lightweight text editors

available, such as Nano, Pico, and Geany. These editors might not have

all of the features of Zed, but they might be a good alternative if you

are looking for something simple and easy to use.

I hope this helps!

Zed is a simple, fast, small, low-CPU-consuming, highly configurable text editor for console and X11.

Installation:

"make -n install" to see what it'll do
"make install"
if you want to customize configurations, copy the config files in your home directory as .zedrc and .zedxrc; if zed'll found error(s) in they, it'll revert to the copy in /etc or /usr/local/etc.
the default configuration for zed (cfg/zedrc, terminal mode) works with LINUX in a LOCAL console and use a trick to retrieve shift status throw linux's kernel. If this isn't your case, use the reduced version of the configuration file (cfg/zedrc.xterm) or use X11 version (zedx).
Using the reduced version you'll loose some nice things, like mark a block with shift-arrow, but it'll work in every ansi/vt100 terminal.
you can configure almost ALL, please read zed.doc.

Here are some key features of "Zed":
Can use ANY keysequence (e.g. define a block with shift-arrow) even under unix local text terminal (linux).
intelligent screen update (NOT using the slow (n)curses).
Column blocks with insert & overwrite.
multi window/multi buffer.
color c++, html, tex, java, mail file.
shows parenthesis matching, searches for C functions, reindents C blocks.
about 200 commands and 100 variables to deal with.
Can edit/insert control codes (ascii 0-31 and 128-159).
executes programs with output redirected on a window (i.e. make, man, etc...).
Can load files with CRLF and/or CR and/or LF end-of-line marker.
clipboard and delete buffer.
savable run-time macros.
simple and powerful configuration system.
easy document mode, almost ascii.
automatic wordwrap and reformat, even inside quoted line within a e-mail file.
small, fast, powerful, low cpu consumer.
hexdump-like mode to edit binary file.
You can go everywhere with the cursor.
Internal, fast file selector.
all that you'll find.

I've got a version compiling from the makefile in an Ubuntu VM.  I'll try attaching a 1.1 MB zip of the build directory here.  If that doesn't go through, let me know where you'd like me to upload it.

The zip contains some symlinks, so unzip it on a Linux system.

I am very close - I think!
When I run zed or zedx, I get:
./zed: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found
(required by ./zed)
./zed: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found
(required by ./zed)

So you must have a newer version of Linux than myself. Not to worry,
your makefile is different from the one I had, so I'll try
recompiling. Maybe that will work?

g++: error: unrecognized command line option ‘-std=c++20’; did you
mean ‘-std=c++2a’?

You also have a newer g++ than me. So I changed the makefile to
c++2a, and tried recompiling. After literally 100's of warnings, I
get:

fatal error: xpm.h: No such file or directory

So, sudo apt-get install libxpm-dev, and try recompiling again:
Success! Well, almost :(

Now when I run zed or zedx, I get:

Zed V1.0.5 by Sandro Serafini (c) 1997/98
Local config not found...
Loading /usr/local/etc/zedrc...
Error: Cannot open/read !

So I guess I need a config file? Wait - isn't that what is in ./cfg ?
Why isn't zed looking there? I don't know :)

Hopefully to be continued!

FYI:

--- cut here: begin --------------------------------------------------

Now when I run the zed or zedx (which is a text editor from 1997), I get:

Zed V1.0.5 by Sandro Serafini (c) 1997/98

Local config not found...

Loading /usr/local/etc/zedrc...

Error: Cannot open/read

--- cut here: end ----------------------------------------------------

===

[<ChatGPT>]

--- cut here: begin --------------------------------------------------

The error messages you are seeing indicate that `zed` (or `zedx`) is having trouble finding and reading its configuration files.

Here is a breakdown of the messages:

1. **Local config not found...**:

      This suggests that `zed` or `zedx` could not find a local

      configuration file. Many applications first look in the user's

      home directory for a configuration, and if they do not find one,

      they resort to a system-wide configuration.

2. **Loading /usr/local/etc/zedrc... Error: Cannot open/read**:

      This is `zed` trying to load a system-wide configuration file

      from `/usr/local/etc/zedrc`. The error indicates that either this

      file does not exist, or there are permissions issues preventing

      it from being read.

Here are some steps to troubleshoot and possibly resolve the issue:

1. **Check if `/usr/local/etc/zedrc` exists**: Use the `ls` command to see if the file is present:

--- cut here: begin --------------------------------------------------

   ls /usr/local/etc/zedrc

--- cut here: end ----------------------------------------------------

   If the file does not exist, you might need to either create it with the correct configuration or reinstall `zed` to ensure the file gets created.

2. **Check permissions**: If the file exists but can not be read, it

                          might be a permissions issue. You can check

                          the permissions with:

--- cut here: begin --------------------------------------------------

   ls -l /usr/local/etc/zedrc

--- cut here: end ----------------------------------------------------

   If the permissions are restrictive, you might want to change them,

   especially the read permissions, so that the user running `zed` can

   access the file.

3. **Local Configuration**:

      If you have a local configuration that you should like `zed` to

      use, make sure it is in the expected location (often this is a

      dotfile in the user's home directory, like `~/.zedrc`).

4. **Reinstall or Manual Configuration**:

      If you have recently installed or updated `zed`, there might have

      been an issue with the installation. Consider reinstalling the

      software. Alternatively, if you are familiar with `zed`'s

      configuration, you can manually create or edit the

      `/usr/local/etc/zedrc` file with the appropriate settings.

5. **Check Documentation**:

      If `zed` came with documentation or a man page, refer to it for

      specifics on configuration file locations and expected formats.

      You can check if there is a man page by typing:

--- cut here: begin --------------------------------------------------

   man zed

--- cut here: end ----------------------------------------------------

Remember, when making changes, especially system-wide ones, it is a

good idea to have backups and understand the implications of the

changes you are making.

[<Llama2>]

It looks like you are trying to run the Zed text editor, but it is not

able to find the local configuration file. The error message indicates

that it is trying to load the configuration file from the

/usr/local/etc/zedrc location, but it is unable to open or read the

file.

Here are a few things you can try to resolve the issue:

 1. -Check if the configuration file exists: Make sure that the zedrc

     file exists in the /usr/local/etc directory. If it does not exist,

     you can create a new file with the same name and add the necessary

     configuration settings.

 2. -Check the permissions: Ensure that the user running the Zed text

     editor has the necessary permissions to read and write to the

     configuration file. You can check the permissions by running the

     ls -l command in the terminal and looking for the permissions for

     the zedrc file.

 3. -Check if the file is corrupted: If the file exists but Zed is

     still unable to read it, it is possible that the file is

     corrupted. Try deleting the file and creating a new one with the

     same name.

 4. -If applicable, check if Zed is installed correctly

FYI:

If you do a search in the source code in the directory and subdirectories 

(e.g. optionally on your Microsoft Windows machine using the unzipped source code)

 grep -i0s zedrc

in the zed 1.0.5 source code you MUST find occurrences of 'zedrc'

(because that specific name occurs in the created error)

and can then (possibly) deduce further actions working from there to resolve it.

if you want to customize configurations, copy the config files in your home directory as .zedrc and .zedxrc; if zed'll found error(s) in they, it'll revert to the copy in /etc or /usr/local/etc.

the default configuration for zed (cfg/zedrc, terminal mode) works with LINUX in a LOCAL console and use a trick to retrieve shift status throw linux's kernel. If this isn't your case, use the reduced version 

of the configuration file (cfg/zedrc.xterm) or use X11 version (zedx).

So adding this (maybe empty if not found) DOT .zedrc and or DOT .zedxrc to your home directory might maybe resolve the issue.

[Guy Rouillier]

Do not install the app. Just run it from your development directory. I didn't consider the app sufficiently finished to use on a regular basis. And with TSE Linux available, I had no motivation to work on zed. 

When you unzipped the file I provided, you should have a symlink zedrc - > cfg/zedrc, and likewise for zedrxc. The app will find these config files in the current directory. Only if it it doesn't find them there will it search elsewhere.

Ok, I did a "locate zedrc" in my Ubuntu VM, and I see both zedrc and zedxrc in /usr/local/etc.  If I remove them, I get the same error you identify below. Sorry, I looked at zed out of curiosity a couple years ago, so didn't really remember what I had to do to get it to work.  We aren't trying to resurrect zed, just see how it creates the X version from the same source as the console version.  So, the easiest thing to do is to put the attached 2 files in /usr/local/etc.  Use "zed --help" for command line options.  I did that, and then tried 

"./zed -cfg ./zedrc zed.doc"

zed ran and tried to use the zedrc in the current directory, which is the version included in the original source zip file (not the zip I sent, but the original one from the author.)  I get the following error:

"Requested shift-status via TIOCLINUX not available !

Please use another configuration or zedx !"

Apparently, I made sufficient changes to the versions of zedrc and zedxrc in /usr/local/etc to get zed and zedx running.

Well, more than I ever really wanted to know, but the command "xlsfonts" will show you the fonts that are available on your system.  Then in the zedxrc file, uncomment the line you commented out that sets the font, and specify one of those.  For example, part of my xlsfonts output is:

7x14

7x14bold

8x13

8x13bold

8x16

8x16kana

8x16romankana

9x15

9x15bold

So in my zedxrc file, I specified

set font 9x15bold

And the next time I started zed, this font was used.

Yes, I can do that.  I'll create a GitHub project for it, since as several people have discovered, locating the source for this zed editor is not straightforward. I believe this code is worth preserving; the author managed to create a useful, if basic, editor with very little code.

Knud, where did you end up creating the repository for the Chris Antos grep that I got working on Linux?  Would be helpful if we got a TSE or Semware group on GitHub so we can collect together all these various projects we are working on.  Sammy, what is your opinion on that, since Semware is your company and TSE is your product?  If you would prefer we don't use the Semware name, we can instead call it semware-users, or friends of TSE. :)

I was too slow on the mark - there is already a semware on github.

I did create:

https://github.com/sammymitchell

I'm happy to host anything you like there.

Editor source will hopefully eventually be put up there,
once I figure github out and clean it up at least a little.

Anyway it is up to you. TSE is freeware now, unencumbered, and
so you are welcome to do whatever is easiest for you. As
noted, I'm happy to host repo's and/or projects there also.

> Knud, where did you end up creating the repository for the Chris Antos grep that I got working on Linux?  Would be helpful if we got a TSE or Semware group on GitHub so we can collect together all these various projects we are working on.

I have already a long time a TSE repository on GitHub, I believe it includes Chris Antos TSE grep also. But as I am not really using it as I mostly/always use only TSE command line grep, not looked into it lately. 

I can e.g. automatically upload / update / download from within TSE a whole directory on GitHub using git.

For file version control I use always Subversion myself from within TSE so that is for me my main program. Almost every of my e.g. TSE programs is maintened locally in Subversion. Each compile in TSE I do calls automatically Subversion, so each day called between 1 to e.g. 100 times.

I plan to look into that GitHib repository some time and plan to come back about it.

I finally am feeling well enough to try some updates of TSE on Linux.  I installed everything and it's definitely working better than the earlier version.

I applied my color themes and I've observed that it doesn't have the high colors, but the upper 8 colors are the same as the lower 8.  See attachments.

Is there a setting?  Or maybe I have some old code in my UI file that's doing it by command?

Rick,

 

Color themes set RGB colors.

The latest Linux release, TSE 4.50 release candidate 10, now supports 16 background colors instead of just 8.

Sammy implied that the next Linux TSE release might support the full 16,777,216 RGB colors as both background and foreground colors.

Then you can apply your color theme.

I just uploaded the latest version. It hopefully will allow you to
use more colors.
What is your TERM environment variable set to?

The latest version (just uploaded) will recognize that, and use the
new color routines.

Even the version before the last one seemed to recognize the 256
colors, but will also download the new version.

Thank you, Sammy. It's so nice to have TSE in Linux!
