Feature request: option to toggle jazz styling of chord symbols

[chrisfargen]

Update: Found the functionality I'm looking for in abc2svg. Here's a screenshot of jazz chords rendered using an automatic chord styling tool in abc2svg. (Source for the extension.)

Here's a [slightly messy] solution that works for individual tunes in abc2svg:

%%beginsvg
<style>
.sup {
        baseline-shift: super;
        font-size:0.66em
}
</style>
%%endsvg

%%staffsep 80px
%%setfont-1 * * class=sup
%%gchordfont sans-serifBold 18
X: 1
T: Cooley's
M: 4/4
L: 1/8
R: reel
K: Emin
|:D2||\

Original post:

It would be nice to incorporate some basic chord symbol styling. Not sure how easy this would be to implement.

I got the result above by manually tweaking the SVG using Chrome DevTools. Here's my procedure:

For each gchord of format [note][accidental][type][/bass]:

1. Leave [note][accidental] as it is.
2. Remove [type] from original <tspan> element and append new <tspan> element with content [type]:

<tspan dy="-0.5em" style="font-size:0.6em">[type]</tspan>

3. Remove [/bass] from original <tspan> element and append new <tspan> element with content [/bass].

   a. If there is a [type] specified before it, move element down so that we're back to baseline:

   <tspan dy="0.5em" style="font-size:0.6em">[/bass]</tspan>

   b. If there is no [type] specified before it, we're already at baseline:

   <tspan style="font-size:0.7em">[/bass]</tspan>

For further consistency, I also did the following:

1. Replace degree symbol ° with lowercase letter o (for diminished chords).
2. Replace hyphen - with en dash – (for minor chords).

Here's the ABC I used for testing:

%%gchordfont 16
X: 1
T: Cooley's
M: 4/4
L: 1/8
R: reel
K: Emin
|:D2||"E-7"EBBA "D7"B2 EB|"G∆7"~B2 AB "C∆7"dBAG|"F#ø7"FDAD "F#m7b5"BDAD|"B7b9"FDAD "Ab9"dAFD|
"G"EBBA "Ab°7"B2 EB|"Amin7"B2 AB "D7sus4"defg|"Gmaj7/B"afe^c "Bb°7"dBAF|"A+7"DE"Eb9"FD "Em6" E2:|

That does look better - and it would solve some spacing issues because the chords would be a little shorter. I guess this should be an option so everyone's music doesn't suddenly look different.

Maybe option could be something like %%stylegchord?

Will be added in beta 36
