From ef897b418a4487196e1dbc18a97046f8f0aea2e8 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Tue, 24 Dec 2024 13:29:32 +0300 Subject: introduced true block and EOL comments * The previous convention of !* ... *! are now true block comments, i.e. they are parsed faster, don't spam the goto table and allow embedding of exclamation marks - only "*!" terminates the comment. * It is therefore now forbidden to have goto labels beginning with "*". * Also support "!!" to introduce EOL comments (like C++'s //). This disallows empty labels, but they weren't useful anyway. This is the shortest way to begin a comment. * All comment labels have been converted to true comments, to ensure that syntax highlighting works correctly. EOL comments are used for single line commented-out code, since it's easiest to uncomment - you don't have to jump to the line end. This is a pure convention / coding style. Other people might do it differently. * It's of course still possible to abuse goto labels as comments as TECO did for ages. * In lexing / syntax highlighting, labels and comments are highlighted differently. * When syntax highlighting, a single "!" will first be highlighted as a label since it's not yet unambiguous. Once you type the second character (* or !), the first character is retroactively styled as a comment as well. --- lib/lexers/xml.tes | 22 +++++++++++----------- 1 file changed, 11 insertions(+), 11 deletions(-) (limited to 'lib/lexers/xml.tes') diff --git a/lib/lexers/xml.tes b/lib/lexers/xml.tes index 87ed9b7..081c2ec 100644 --- a/lib/lexers/xml.tes +++ b/lib/lexers/xml.tes @@ -1,4 +1,4 @@ -!
