   6 # This is a Makefile to generate the PO files for automated
   7 # translation. If you get through the trouble of creating PO file for
   8 # your language, you will save a lot of hassles with editing plain html
   9 # and repeated text, which also implies potential mistakes.
  10
  11 # Please read the manual on the page:
  12 # https://po4a.org/man/man1/po4a.1.php
  13
  14 # This Makefile only contains commands from the manual tested for the
  15 # esd translation.
  16
  17 # After the translation of the PO file has been finished, generate new
  18 # files using: make -f Makefile.gen
  19
  20 # flags for the po4a-getextize
  21 PO4A_FLAGS=-M utf-8 -f xhtml -o porefs=none \
  22            -o 'untranslated=<script>' \
  23            -o 'attributes=<meta>content' \

  33 # Initialise the po template from English version, this is to be used,
  34 # there is no translation for now, and you are going to build it from
  35 # scratch. Then copy the file esd-temp.pot to your language file
  36 # esd-$(lang).po such as esd-cs.po, and edit it in your favourite PO
  37 # editor (such as poedit, or emacs with po-mode).
  38
  39 # If you already have an old translation you can convert it to PO
  40 # files as described bellow.
  41 esd-temp.pot: $(foreach f,$(SRC),en/$f)
  42         po4a-gettextize $(PO4A_FLAGS) $(foreach f,$+,-m $f) -p $@

  45 # Convert existing translations into PO files.
  46
  47 # NOTE: You need to make sure that your translated document is formaly
  48 # correct xhtml (there might be accidental mistakes).
  49 # Validate your document to find errors (e.g. https://validator.w3.org)
  50
  51 # IMPORTANT: when you generate the PO files from the existing
  52 # translation, the original files in the version *corresponding* to
  53 # the translation have to be provided as a command line argument (with
  54 # parameter -m).
  55
  56 # for that specify the directory where the original files are placed
  57 DIR=en
  58 # and the list of files that were translated within the corresponding
  59 # version
  60 FILES=$(SRC)
  61
  62 # The generation of the PO file is likely to go wrong, because of the
  63 # mistakes which were introduced by the direct translation of the html
  64 # files. In this case the po4a gives quite good error message with a
  65 # reference in which file and line number to look at to find the
  66 # mistake. Go to that file and try to correct the errors and then
  67 # repeat the procedure.
  68
  69 # Don't give up. Translating PO files is nicer.
  70
  71 # For more details and troubleshooting see:
  72 # https://po4a.org/man/man7/po4a.7.php
  73 # in section: HOWTO convert a pre-existing translation to po4a?
