abc2abc – a simple abc checker/re-formatter/transposer
Synopsis
abc2abc file [ -s ] [ -n ] [ -b ] [ -r ] [ -e ] [ -t semitones ] [ -nda ] [ -u ] [ -d ] [ -v ] [ -v] [-nokeys] [ -nokeyf] [ -usekey(sharps/flats)] [ -OCC ]Description
abc2abc is a simple abc checker/re-formatter/transposer. It will check whether the file given on the command line obeys basic abc syntax.If you want to check an abc tune, it is recommended that you use abc2midi with the -c option. This performs extra checks that abc2abc does not do.
The output of abc2abc goes to standard output. Use redirection to save it to a file.
Options
- -s
- Rework spacing in the file (which affects how notes are beamed together when the music is printed out). This option does not appear to be working correctly.
- -n X
- Reformats the abc file with line breaks every X bars.
- -b
- Don’t do bar checking.
- -r
- Don’t do repeat checking.
- -e
- Don’t report errors.
- -t n
- Transpose tune by n semitones. This function will also work with K: none or one of -nokeys or -nokeyf. If a voice is assigned to channel 10 (drum channel) using a %%MIDI channel 10 command, then this voice is never transposed.
- -nda
- Convert double accidentals in guitar chord to another chord though strictly not correct.
- -u
- Update notation; the older notation + + for chords is replaced by [] and s s for slurs is replaced by ().
- -OCC
- Accept the old notation for chord. Normally this is turned off, since it conflicts with abc draft standard version 2.0 for decorations (eg. +crescendo(+).
- -d
- Re-notate the tune with all note lengths doubled. The unit length specified by the L: field command is halved (e.g. L:1/8 to L:1/16).
- -v
- Re-notate the tune with all note lengths halved. The unit length specified by the L: field command is doubled (e.g. L:1/8 to L:1/4).
- -ver
- Prints version number and exits.
- -V X
- For multivoiced abc files (i.e. contains V: field commands), only voice X is copied.
- -X n
- For a file containing many tunes, the X: reference numbers are renumbered sequentially starting from number n.
- -nokeys
- No key signature will be assumed. Instead, sharps and naturals will be placed wherever they are needed.
- -nokeyf
- No key signature will be assumed. Instead, flats and naturals will be placed wherever they are needed.
- -usekey sf
- This will force abc2abc to output the notes in the key signature keys[sf] where sf specifies the number of flats (-negative) or sharps (+positive) in the key signature. It is a number between -5 and +5 inclusive.
* Normally abc2abc will convert the deprecated notation for decorations (eg. !ppp!) to the abc version 2.0 draft standard (eg. +ppp+). If you do not wish to change to this standard include the -OCC flag.
