Hi,

I omitted RET after \table-math-swell

It is

\table-math-swell RET ->

After that it should work. I did not try it this time so if it does not work pls. try

\table-math-swell RET

after which you can go back to the WYSIWYG and type \macrolx RET inside a math _expression_ to use the macro.

For the solution, the easiest one is to give them a blank document with the macro already in the preamble. The best solution is to put this into a package, but if you do not mind I shall postpone the package to tomorrow.

Pls. let me know if the corrected macro works.

For the style writing, my impression is that we need a complete worked-out example written by someone who knows how to write a style file (with step-by step explanations); it is probably easier to learn from that than by examining TeXmacs default style files. What I am not able to do now are the sectioning commands and the commands for itemization and enumeration lists, and most probably many other important things too.

thanks Giovanni

after somewhat 7-8 attemps i obtain this but it differd from what you sent to me because i have typed as you said a \ before "table" and it does not appear by your screenshot

if y dont type it, then the typography of "table-math-swell" is not italic wheras on your screenshot it is

the problem for me is now : what shall i do

i tried to press return somewhere without any success ;  then i went to document>part>show all, thinking it was the thing to do

but how can i can this macro

i precise it is the first time at all i type a macro

i precisze also that two persons asked me simultaneously the question so it is for them ; in these conditions, if i succeed to make it work, do you think there is a solution to export it to them ?

i am impressed by the complexity of TeXmacs' macro, but dreamt for a long time to be able to enter in the code one day

my aim would be : creating my own style ; one day i may be ready to ask some help for that on the forum

good evening to you !

I suspect it is easy to follow only when typing in "source mode", otherwise the activation of the macros makes them "disappear" (I hope I understood correctly that you are typing the macro in text mode)

I did it by first generating the preamble (which puts one automatically in source mode), in this case the math-table-base does not disappear. You find the command for generating the preamble under     Document->Part

Then there are two ways to do it. Either type the entire sequence (see below) or copy the macro from the the "Edit macro" menu command while inside a "Choice" environment (in WYSIWYG mode), paste it into the preamble, and make the substitutions there (exchange the roles of left and right). Let me know if you want more details on this, which could be the easiest method.

The sequence is the following, I hope I got all steps right and that it makes enough sense that you are seeing where the key presses should bring you. The final look is

<meljbjflifdeedda.png>

I have succeeded writing first both \left, \right, then going back with twice left arrow to add the \tformat part, but not writing first \left and \tformat (could not go to the right place where to write \right). I found it necessary as well to insert \table-math-swell with the backslash (cell-swell is already in a position that takes the environment variables as default, so I did not need to place a backslash before it.

-> is right arrow, <- is left arrow.

\assign RET

macrolx ->

\macro RET TAB <-

x ->

\math-table-base RET

\left RET

. ->

\right RET

} <- <-

\tformat RET

\cwith RET

1 ->

-1 ->

1 ->

-1 ->

cell-swell ->

\table-math-swell ->

TAB

\x RET

After this the macro is available.

If you place the cursor towards the end of the macro definition (I did not investigate precisely) and press return it changes formatting, but it seems to me that this is just the presentation.

hi Giovannithanks for your answer and proposition

yes indeed i would need some help

i think i understand your typiing as :

<PastedGraphic-13.png>

but when i press "enter" or right arrow, what usually makes the | appear, here the math-table-base disappear

Waiting for someone else to comment, I propose this

<assign|rightChoice|<\macro|x>   <math-table-base|<left|.><tformat|<cwith|1|-1|1|-1|cell-swell|<value|table-math-swell>>|<arg|x>><right|}>>
  \;
</macro>>

I started from the macro that defines choice (that I got from the "Edit macro" menu command) and I moved both the brace from left to right and the point from right to left. I do not master yet the editing of macros in the TeXmacs source mode, but it worked and it gives what you want as far as I can tell. Let me know if you need step by step instructions to make it work.

bonjour

two TeXmacs users ask me how to make right l'accolade } , thus the symétric of \choice

i mean not only typing } but having this :

x=1|

   |->x+y=3

y=2|

with a large vertical } instead of the |->
