Muse2ps feature requests and bug reports

Feature Requests and Bugs

This page list feature requests and bug reports for muse2ps which is a command-line typesetting program for MuseData.

Bugs

Spacing of dummy time signatures

When a time signature is not given at the start of the music, the space between the clef and the first note is good. When a dummy time signature is given (such as T:9/0), there is extra space added between the clef and the first note which appears to be the width of a cut-time metrical sign. It would probably be a good idea to set the width of a dummy time signature to 0. Illustration of the extra space and comparing between the various time signature settings:

MuseData for example: sanctustimesig.md2.

Echoing initial comment lines with =M

It would be useful to echo comments from the start of the muse2ps input data (which are commonly used to store muse2ps formatting options) into the data comments created with the =M option. In addition, any text after the /END> line (or /FINE line, but before the /eof line should be echoed into the PostScript comments related to the =M option. This feature is needed to preserve muse2ps options with the embedded MuseData, as well as transmit page footer information to programs further down the command pipeline.

Clef/key/time signature suppression at indented line breaks

It would be useful to create a print suggestion which suppresses printing of cautionary time singature, key signature or clefs at the end of a line, particularly when an indented line break code is used. Alternatively, suppression of cautionary symbols at the end of systems before an indented line break could be a hard-coded default (similar to the repetition of the instrument names at the start of the system at indented line breaks). In the following example, it is desired to suppress printing of the region marked in red.

MuseData for example: indentsuppress.md2.

Initial measure number

For short examples which do not start at measure 1, it would be useful to allow adding a bar number at the start of the music.

Stage 1 preprocessing of data

It would be useful to add components of the stage1 → stage2 process: (1) have an option which turns on automatic determination of stem directions, (2) have an option which turns on automatic determination of beaming. These would preferably be separate options, since it is more likely that input data from other sources would have beaming information, but not stemming information.

Finished features and fixed bugs

Independent barline styles

MuseData for example: polybar.md2.

Invisible time signatures

Allow for "invisible" time signatures.

MuseData for example: notime.md2.

Invisible barlines

Allow for "invisible" barlines (such as ending a short example with an incomplete barline).

Here is an example of an implicit invisible barline which is created by not placing a barline at the end of the music:

MuseData for example: nobaratend.md2

And here is an example of an explicit invisible barline which is created by inserting an invisible barline in the data:

MuseData for example: invisible_barline.md2

Paper size in PostScript DSC comments

Add the following line at the end of the DSC comment header in the PostScript output:
