#!/usr/bin/env python3 # # Fill in a template with data from fields in an ABC file. # Fields have any ABC accented characters converted to HTML (default) or Latex. # # Rearrange some field contents into display format: # * In Title fields, change 'sort' form such as 'Exploding Potato, The' # to display format 'The Exploding Potato'. # * In Key fields, translate the ABC key representation to full text, # e.g. G#dor becomes G# Dorian. # # Recognise continuation header fields and print those too. The ABC standard # defines continuation fields as starting ':+'. Regrettably none of the tools # I am using the Booke recognise that syntax, so I am adopting a Booke # convention of '<header>:+' *also* being a continuation. Note that a # continuation is a distinct line in the field value; the value has a line # break between it and the previous line. # # Templates are read from file, and are in Python standard library format. # The following values are substituted: # * name. The file base name. Base filename without extension. # * title. The tune title. # * subtitle. The tune subtitle (second Title field), if any. # * fulltitle. The tune title followed, if it exists, by " (" subtitle ")" # * tradition. The Morris tradition the dance tune is from. # * composer. The tune composer. # * key. The tune key. # * parts. The tune parts order (A(AB2)3 etc.). # * changefile. The name of the 'change' file, if any. # * changename. The change file base name. # * changetitle. The change file tune title. # * changevisibility. "yes" if there's a change value, otherwise "no". # * credit. The 'credit' value. # * creditvisibility. "yes" if there's a credit value, otherwise "no". # import argparse import pathlib import string from abcfield import getFieldDisplayText, getFullTitle def getFileData(f, latex): res = {} input_path = pathlib.Path(args.input.name) res["name"] = input_path.stem fdir = input_path.parent lines = f.readlines() res["title"] = getFieldDisplayText(lines, fdir, "T", latex=latex) res["subtitle"] = getFieldDisplayText(lines, fdir, "T", n=2, latex=latex) res["fulltitle"] = getFullTitle(lines, fdir, latex=latex) res["tradition"] = getFieldDisplayText(lines, fdir, "A", latex=latex) res["composer"] = getFieldDisplayText(lines, fdir, "C", latex=latex) res["key"] = getFieldDisplayText(lines, fdir, "K", latex=latex) res["parts"] = getFieldDisplayText(lines, fdir, "P", latex=latex) res["notes"] = getFieldDisplayText(lines, fdir, "N", starts="Dottes:", latex=latex) res["history"] = getFieldDisplayText(lines, fdir, "H", starts="Dottes:", latex=latex) return res if __name__ == "__main__": parser = argparse.ArgumentParser(description='Substitute values from ABC file into template.') parser.add_argument('-l', '--latex', dest='latex', action='store_true', help='output LaTeX formatted values (default is HTML)') parser.add_argument('-t', '--template', dest='template', type=argparse.FileType('r'), required=True, help='template file') parser.add_argument('-v', '--value', dest='values', action="append", default=[], help='define var=value items for templater') parser.add_argument('-n', '--next', dest='nextfile', type=argparse.FileType('r'), help='next tune file') parser.add_argument('-p', '--prev', dest='prevfile', type=argparse.FileType('r'), help='previous tune file') parser.add_argument('input', type=argparse.FileType('r'), help='input ABC file') args = parser.parse_args() fields = getFileData(args.input, args.latex) vars = {} vars["notesvisibility"] = "no" vars["historyvisibility"] = "no" for name in ["name", "title", "subtitle", "fulltitle", "tradition", "composer", "key", "parts", "notes", "history"]: vars[name] = fields[name] if vars["notes"]: vars["notesvisibility"] = "yes" if vars["history"]: vars["historyvisibility"] = "yes" if args.nextfile: fields = getFileData(args.nextfile, args.latex) for name in ["name", "title", "subtitle", "fulltitle"]: vars["next" + name] = fields[name] if args.nextfile else "" if args.prevfile: fields = getFileData(args.prevfile, args.latex) for name in ["name", "title", "subtitle", "fulltitle"]: vars["prev" + name] = fields[name] if args.prevfile else "" for val in args.values: keyval = val.partition("=") vars[keyval[0]] = keyval[2] print(string.Template(args.template.read()).substitute(vars))
