# i18n functions that takes a context argument (tp, tpx, tnp, tnpx) |
18 |
# are deliberately not defined as filters. |
19 |
# Because context is the first argument, this would require writing: |
20 |
# [% 'context' | tp('message') %] |
21 |
# Whereas we'd prefer to write: |
22 |
# [% 'message' | tp('context') %] |
23 |
# There are two ways to fix this: |
24 |
# 1. Change the order of arguments in Koha::Template::Plugin::I18N and |
25 |
# change the -k options in xgettext-tt2 (the msgid must be first), or |
26 |
# 2. Use different keywords, and add them as -k options in xgettext-tt2 |
