It is in legacy format and of questionable quality. Ideally it should be contributed upstream from where it will eventually trickle down to us. - lexers/git-rebase: convert to new lexer format (cherry picked from commit 4000a4cc9ac4a4c2869dfae772b977a82aee8d8c) - lexers/strace: convert to new lexer format (cherry picked from commit e420451320d97eb164f5629c1bcfab0b595be29d) - lexers/typescript: add new upstream lexer revision 28e2b60 (cherry picked from commit 7326e6deecdaa75fa94ae9ebdb653f9f907b33f2) - use `package.searchpath` instead of a local `searchpath` function - Restore `filetype: support filetype detection via hashbang` - Remove redundant comment - Restore gemini lexer --- lua/lexers/django.lua | 94 ++++++++++++++++++++------------------------------- 1 file changed, 36 insertions(+), 58 deletions(-) (limited to 'lua/lexers/django.lua') diff --git a/lua/lexers/django.lua b/lua/lexers/django.lua index a671006..2147853 100644 --- a/lua/lexers/django.lua +++ b/lua/lexers/django.lua @@ -1,77 +1,55 @@ --- Copyright 2006-2017 Mitchell mitchell.att.foicica.com.
