[TeXmacs] Shortcut for R session

Hi

I would like to know if there is a keyboard shortcut to insert a R 
session ?

Thanks

Re: [TeXmacs] changes in the maxima plugin's output?

It also seems that you can't insert a "$" at the end of the 
maxima input line any more: TeXmacs goes into math mode.
Do you see that?

[TeXmacs] session maxima; session tableur ?

salut à tous

je suis sous os X.6.7

quand je fais "insérer session maxima", la session se fait, mais il y a toujours marqué "en cours" et
aucune instruction ne donne de résultat

---

question n°2

existe-t-il des logiciels tournant en session sous texmacs et permettant de faire des petits tableurs,
avec simplement les 4 opérations et des calculs de recopie automatique ?

I don't know French, but I guess maxima session doesn't work for you.

1. Does command-line maxima work normally? Is it in the PATH?

2. What does

maxima --list-avail

produce? For example, on my Linux box it produces

grozin <at> elrond ~ $ maxima --list-avail
Available versions:
version 5.24.0, lisp cmucl
version 5.24.0, lisp ecl
version 5.24.0, lisp clisp
version 5.24.0, lisp gcl
version 5.24.0, lisp sbcl
version 5.24.0, lisp openmcl
grozin <at> elrond ~ $

3. What does the script maxima_detect write? On my box

grozin <at> elrond ~ $ /usr/libexec/TeXmacs/bin/maxima_detect
(
"5.24.0 cmucl"
"5.24.0 ecl"
"5.24.0 clisp"

Oui, giac/xcas fait ca (en plus du calcul formel largement compatible avec maple),
Ouvrir une session giac dans texmacs puis utiliser la commande 
spreadsheet("nom_de_fichier_du_tableur")
De meme la commande geo2d ou geo3d permet d'avoir une figure de geometrie
interactive depuis texmacs.

Are you sure you have maxima installed on your computer?

If it is installed, then typing just

maxima

in a terminal window should start command-line maxima. Only after you have 
it working, you can try to call maxima from other programs, like TeXmacs.

[TeXmacs] Cleaning up texmacs file for git

This entry in .gitattributes:
*.tm    filter=texmacs

and this entry in the .gitconfig file:
[filter "texmacs"]
         clean = "sed -e '/^<[^>]*>/h;x;/references\\|auxiliary/{x;d};x'"

means that .tm files are commited to git without the references or 
auxilliary sections.
When merging from git branches I so often get conflicts in those 
sections which can easily be regenerated.

The sed command is, but has been escaped appropriately above for the 
.gitconfig file
sed -e '/^<[^>]*>/h;x;/references\|auxiliary/{x;d};x'

Here is a better clean-up which can also remove table-of-contents (which 
can also be re-generated):

#! /bin/sed -f

/^\( *<.table-of-contents\|<.references\|<.auxiliary\)/{h;/<\\/p};x;/^ 
*<\\/{x;d};x

called git-fix-texmacs, so the clean entry in [filter "texmacs"] would 
need pointing to where-ever this +x 1 line script is saved.

Re: [TeXmacs] Cleaning up texmacs file for git

Trailing whitespace in texmacs gives git-whitespace warnings; and it has 
brought me trouble before when I used Lyx,

I'm looking at some git clean-filter cleanups that can find an 
alternative representation.

To demonstrate, I'll use _ to represent space.

The line:

---8<------8<---
hello__
---8<------8<---

is stored in texmacs as:
---8<------8<---
hello_\_
---8<------8<---

But it seems like this representation will do as well:

---8<------8<---
hello_\_\

---8<---

It seems like an extra \ and new-line can be suffixed onto a trailing 
space and the document still parse as normal; I applied this sed to a 
document:

sed -e 's/ $/ \\\n/'

and then loaded and re-saved the document and it was restored to it's 
original form.

So... does anyone have any comments on a git clean commit script adding 
\\\n to the end of lines ending in white space so that there are no 
longer lines ending in white space?
