Fortunately, you do not need to learn the Scheme programming language
to write scripts for Denemo to do simple things such as inserting bits
of LilyPond syntax. Several users have created scripts to do various
tasks, some of them are now shipped with Denemo

Well, no part of the source code needs changing, you are able to have
your own local commands that are stored in your own directory and have
all the status of the commands shipped with Denemo (most of Denemo's
menus comprise scripts which are interpreted when you invoke them).

yes

The Scheme script would invoke procedures that are part of the source
code of the Denemo program, written in C.

Yes, Denemo can pass the syntax that LilyPond needs and optionally
display any glyph from the LilyPond (or any other) fonts as needed. All
this can be done by the user themselves. But as there are several
thousand Denemo commands that can be invoked you will probably need
help to find your way around - I'm always happy to help, as this is the
best fun, exploiting all the power under the bonnet.

Richard:

Not sure about this.   I am not a programmer, so could you please direct a source to learn Scheme.   Because I do not read well, would you tell me which part of Scheme I should know to do this?

I would assume that there are libraries in Scheme.  One for placing # and b simples in the tool section of Denemo.  And I am going to guess the #’’s and b’s come from Lilypond to a Scheme library to place them in the work space.  Would you direct me to the section of Scheme code that works with the accidentals?  I know there are other dependent sections from what you said above.   This may be far off base, but I would like to see some code.    I am using windows, so is there a simple IDE that I would need?

Thank you, ƒ
