Passing variables from the command line

#1

I’m creating a batch of PDF documents in TeXmacs using data loaded from a CSV file. I want to automate the process so I can pass an argument on the command line that tells texmacs which row of the CSV to read.

Initially I thought I could just do texmacs -x "(define row-nr 8)" myfile.tm and be done with it, but this gives an error: Missing body expression.

I have found that I can define a variable in a .scm file and load that file with -x (load "row-nr.scm"), but that’s no so convenient to use in a shell script, for example.

I also found that I can do -x '(setenv "ROW_NR" "8")' and then do (getenv "ROW_NR") in TeXmacs (or of course just ROW_NR=8 texmacs .... This is probably the easiest solution.

I’m posting this here in case these solutions are useful to anyone. Please let me know if you have better solutions!

Hi jeroen, why not do

texmacs -x "(begin
(load-buffer \"a.tm\")
(load-csv 8))"
#3

Then ‘load-csv’ would load the date and manipulate the document tree with tree-set!? That would work as well. You can also define a variable in a .scm file, load that and then use set! from -x.
