convert.ly errors

[Jean Louis Thiry]

Hello everyone,

When using convert.ly (\version “2.23.12”) everything is fine as I do not work on complex scores. 

But if I compile a 2.19.81 file, for example, converted into 2.23.12 everything goes well except for a few errors (always the same) which seem to have been overlooked by convert-ly during the conversion.

In the case of my old files which compile well with 2.18.2 or 2.19.81, 
\override ChordName #'font-series = #’bold

I have to manually transform this declaration into:
\override ChordName.font-series = #’bold

or: top-markup-spacing #'basic-distance=#0
which becomes
top-markup-spacing.basic-distance=#0

The messages are:

/Users/JLT/Documents/Lilypond/Partitions/Irlandais/Poll Ha'Penny/Poll-Ha-Penny.ly:87:23: Avertissement : deprecated: missing `.' in property path ChordName.font-series

\override ChordName

#'font-series = #’bold

/Users/JLT/Documents/Lilypond/Partitions/Irlandais/Poll Ha'Penny/Poll-Ha-Penny.ly:184:19: Avertissement : deprecated: missing `.' in property path Beam.length-fraction

\override Beam

#'length-fraction = #1.2

/Users/JLT/Documents/Lilypond/Partitions/Irlandais/Poll Ha'Penny/Poll-Ha-Penny.ly:185:19: Avertissement : deprecated: missing `.' in property path Tie.thickness

\override Tie

#'thickness = #3

So my question is: is this an oversight in the writing of convert.ly or is it too complicated to implement this control in the conversion process of convert.ly?

Thank you
