Mogan v1.1.2 Roadmap

darcy · December 13, 2022, 9:15am

I do not like the Emacs way. I love the KISS principle. That’s why I want to release Mogan Code.

And I do not like Wechat Pay. I prefer Alipay. I do not like shopping on Wechat, I prefer Taobao/JD/Pingduoduo.

Having the possibility of loading files on the webasm port could be great. Let me explain to you what I have in mind as long term goals: all is related to UI cannot be easily done with wasm since the marshalling of objects and the handling of DOM are not directly supported. You have to do it via javascript. So the idea is to have a UI client code written in javascript which interact with the browser and the user and on a different thread a worker server which implements the TeXmacs document format and typeset it to bitmaps which are sent back to the browser for visualisation. One can improve the protocol to allow local refresh. To have an idea of the kind of architecture I’m taking about one can look at the mupdf wasm viewer demo here: https://mupdf.com/wasm/demo/view.html?file=../../docs/mupdf_explored.pdf

which is structured as I described above.

Also: I have a working branch of TeXmacs which uses mupdf for onscreen reddening, so that it is independent of Qt graphics libraries. This is part of the above effort to make a small core with TeXmacs+mupdf+s7 which can render documents without needing large frameworks.

Mogan is a non-profit project. As the original author of Mogan, I just wanna to do what I want to do. That’s my long-term plan. If you do not like Mogan XYZ, just ignore it and stick to GNU TeXmacs or Mogan.

darcy · December 13, 2022, 9:29am

There are principles and philosophies. I care less on those things, I just want to make tools for myself.

If other developers agree with me, they could join me on Mogan Code development. That’s all!

pireddag · December 13, 2022, 1:59pm

IMHO for that we also need to make it easier for people to contribute.

A good step would be making resources easier to find; this could encourage people to improve on an existing plugin or write their own.

I see the following:

tm-forge and blog

put a link on TeXmacs website and a link on the forum, (in the forum the link should be pinned both for guests and logged-in users)

further:

for tm-forge, a different organization so that it is easier to find out what it is there and to download it

Other things that would IMHO encourage people to contribute:

again for plugin development, indicate on the website a way to publish and advertise plugins without being part of the team; on http://www.texmacs.org/tmweb/contribute/develop.en.html there is an invitation to join the team, but this might be too big of a commitment for some people

for the forum:

making it so that [wiki] Assorted code snippets to customize TeXmacs' behaviour is pinned at the top even when users are logged in. In the current state, I often forget that the post exists. The same holds for Tell us the most impressive features of GNU TeXmacs!, which will disappear from my awareness in a short time in the current state where it slides down with each new post

darcy · December 13, 2022, 2:02pm

Have you ever tried Mogan?

Planet in Mogan could be viewed in Mogan itself, without opening web browsers.

@mgubi Are you interested to merge tm-forge/blog/planet into one planet?

A planet:

Community Driven
Could be viewed within GNU TeXmacs or Mogan
Could be viewed in Web Browsers

I think some resources in tm-forge should be maintained as a plugin. And I’m planning to start the plugin center in Mogan v1.1.3.

pireddag · December 13, 2022, 2:04pm

I tried a previous version. Maybe at that time it was almost the same as TeXmacs. Let me try it again.

pireddag · December 13, 2022, 2:22pm

Do I have to compile it for Ubuntu?

darcy · December 13, 2022, 2:34pm

Yes. https://mogan.app/guide/Develop_on_Linux.html

The build process is very smoothy. Hope you try it and open the XmacsLabs Planet via Help->Planet.

xuyiqi1 · December 13, 2022, 2:46pm

Please remember that the documents under Help → Planet are primarily written in Chinese.

pireddag · December 13, 2022, 2:58pm

Thanks.
Two questions

I am using xmake:

c++: fatal error: cannot specify ‘-o’ with ‘-c’, ‘-S’ or ‘-E’ with multiple files

what to do?

How do I compile with many processors?

darcy · December 13, 2022, 3:55pm

Please describe in detail how you get this fatal error.

pireddag · December 13, 2022, 4:12pm

Issuing xmake.

Here is the output of xmake:

note: CMakeLists.txt found, try building it or you can run `xmake f --trybuild=` to set buildsystem (pass -y or --confirm=y/n/d to skip confirm)?

Solution 1

Try input n? Mogan prefers xmake rather than cmake.

It seems there is a compatible mode for cmake in xmake. Please do not use cmake.

Solution 2

          xmake build --yes --verbose --diagnosis --jobs=8 --all

Solution 3: wait me to improve the dev guide

pireddag · December 13, 2022, 4:58pm

This fails in the following way:

note: CMakeLists.txt found, try building it or you can run `xmake f --trybuild=` to set buildsystem (pass -y or --confirm=y/n/d to skip confirm)?
please input: y (y/n)
n
note: xmake.lua not found, try generating it (pass -y or --confirm=y/n/d to skip confirm)?
please input: n (y/n)
y
xmake.lua not found, scanning files ..

just use xmake in the root dir (do not enter the build dir), like

git clone xxx
cd mogan
xmake

or

git clone xxx
cd mogan
xmake build --yes --verbose --diagnosis --jobs=8 --all

You can always learn from CI yaml file: https://gitee.com/XmacsLabs/mogan/blob/main/.github/workflows/ci-xmake.yaml#L108-141

pireddag · December 13, 2022, 5:29pm

I had issued xmake in the root dir, but starting from the release at https://github.com/XmacsLabs/mogan/releases/tag/v1.1.1

Now starting by cloning the code at the repository at https://github.com/XmacsLabs/mogan the compilation succeeds and the unit tests are ok.

The program crashes at startup, it looks like it does not like something about my TeXmacs installation. I will investigate more later.

—It is easier than compiling TeXmacs, which I never could do

I do have one more question in the meantime. As a first step in the compilation, xmake made me install the following:

note: install or modify (m) these packages (pass -y to skip confirm)?
in xmake-repo:
  -> libpng v1.6.37 
  -> libiconv 1.17 
  -> libjpeg v9e 
  -> libcurl 7.84.0 
  -> freetype 2.12.1 
  -> sqlite3 3.39.0+200

Is this going to interfere with packages with the same name installed with apt?

pireddag · December 13, 2022, 8:28pm

Ok, made it, I had first to issue

export TEXMACS_PATH=

It looks nice. I like the icons.
Of course now I have to learn Chinese to read XmacsLabs Planet

BTW I still would appreciate some info about the packages that xmake installed (see message above).

darcy · December 14, 2022, 12:29am

No. All these dependencies are installed in $HOME/.xmake, it is in user space and only visible to xmake.

darcy · December 14, 2022, 12:31am

Follow the five steps, https://mogan.app/guide/Develop_on_Linux.html#using-xmake

export TEXMACS_PATH is not needed. I guess you have ignored step 4.
