[Scilab-users] replacing sed command by regexp ?

[Clément David]

Hello Philippe,

About replacing "%foo_" to "foo_" in a file, I crafted an example using strsplit() and strcat() (see
attached) but it might be good to have an extended strsubst() that can output groups (\1 in your
regexp).

Do not hesitate to report a bug on that,

this is a file containing
some %foo_ references and
also some %bar_ related
contents

And that's it !
