From c0778a3d0eab0dab2693be70365f573d7bec1579 Mon Sep 17 00:00:00 2001 From: Georg Baum Date: Fri, 21 Jan 2011 18:29:10 +0000 Subject: [PATCH] Translate all known box insets. This is needed since the super-clever preamble parser discards all needed packages like calc.sty or framed.sty, so the resulting document would be uncompilable with those boxes as ERT. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@37287 a592a061-630c-0410-9148-cb99ea01b6c8 --- src/tex2lyx/Parser.cpp | 16 +- src/tex2lyx/TODO.txt | 3 - .../test/box-color-size-space-align.tex | 14 + src/tex2lyx/text.cpp | 248 ++++++++++++++---- 4 files changed, 221 insertions(+), 60 deletions(-) diff --git a/src/tex2lyx/Parser.cpp b/src/tex2lyx/Parser.cpp index 4cdb9a0d8d..d2998bf9e2 100644 --- a/src/tex2lyx/Parser.cpp +++ b/src/tex2lyx/Parser.cpp @@ -266,9 +266,13 @@ bool Parser::skip_spaces(bool skip_comments) } if ((curr_token().cat() == catComment && curr_token().cs().empty())) continue; - if (skip_comments && curr_token().cat() == catComment) - cerr << " Ignoring comment: " << curr_token().asInput(); - else { + if (skip_comments && curr_token().cat() == catComment) { + // If positions_ is not empty we are doing some kind + // of look ahead + if (!positions_.empty()) + cerr << " Ignoring comment: " + << curr_token().asInput(); + } else { putback(); break; } @@ -285,7 +289,11 @@ void Parser::unskip_spaces(bool skip_comments) putback(); else if (skip_comments && curr_token().cat() == catComment) { // TODO: Get rid of this - cerr << "Unignoring comment: " << curr_token().asInput(); + // If positions_ is not empty we are doing some kind + // of look ahead + if (!positions_.empty()) + cerr << "Unignoring comment: " + << curr_token().asInput(); putback(); } else diff --git a/src/tex2lyx/TODO.txt b/src/tex2lyx/TODO.txt index b38c173442..97586f361a 100644 --- a/src/tex2lyx/TODO.txt +++ b/src/tex2lyx/TODO.txt @@ -15,13 +15,10 @@ Format LaTeX feature LyX feature lib/external_templates.
