[Texmacs-dev] Hiding the Title menu in 1.0.1

[David Allouche]

In 1.0.1 there was a change in when the Text->Title menu is displayed.

Older versions had in text-menu.scm (and similarly in icon-menu.scm):

    (define text-menu
      '((if (style-has? "header-title-dtd")
            (-> "Title" (link title-menu)))
        (if (style-has? "header-letter-dtd")
            (if (not (inside? "letter-header"))
                (-> "Header" (link letter-menu)))
            (if (inside? "letter-header")
                (-> "Letter" (link letter-header-menu))))
        (if (style-has? "header-exam-dtd")
            (-> "Header" (link exam-header-menu)))
        ...))

My proposed change was:

    (define text-menu
      '((if (style-has? "header-title-dtd")
            (-> "Title" (link title-menu)))
        (if (style-has? "header-letter-dtd")
            (-> "Header" (link letter-header-menu)))
        (if (style-has? "header-exam-dtd")
            (-> "Header" (link exam-header-menu)))
        ...))

And the applied change was:

    (define text-menu
      '((if (and (style-has? "header-title-dtd")
                 (not (style-has? "header-letter-dtd"))
                 (not (style-has? "header-exam-dtd")))
            (-> "Title" (link title-menu)))
        (if (style-has? "header-letter-dtd")
            (-> "Header" (link letter-header-menu)))
        (if (style-has? "header-exam-dtd")
            (-> "Header" (link exam-header-menu)))
        ...))

What that means is that the GUI now get out of its way to to hide the
Text->Title menus in styles which have classical, article-like title
feature and the title features of the letter or exam styles.

Why is that? I see no obvious reason to do so.

It may be useful to have both titles in the same document. For example
a letter may start with a classical letter title and header, and then
use article-style title and sectionning for attached documentation.
