Use the patch from the attachment for ELinks-0.12.GIT. I hope it works as expected. I have no write permission to the main branch, so you must ask someone to commit it. -- Witek
viewer: Added new four actions requested by Ligesh.
move-link-down-line moves the cursor down to the line with a link. move-link-up-line moves the cursor up to the line with a link. move-link-prev-line moves to the previous link horizontally. move-link-next-line moves to the next link horizontally. --- commit 7882384bce49ab8d09e4c6d7a4b7b0eb0c945797 tree a8b3e69e402f3f5fe74f4676e196d5af83f9d536 parent ee83dca303963e26f5811fab895283e2e70cd2b9 author Witold Filipczyk <[EMAIL PROTECTED]> Sat, 11 Aug 2007 23:06:10 +0200 committer Witold Filipczyk <[EMAIL PROTECTED]> Sat, 11 Aug 2007 23:06:10 +0200 src/config/actions-main.inc | 4 + src/viewer/action.c | 16 ++++++ src/viewer/text/link.c | 2 - src/viewer/text/link.h | 3 + src/viewer/text/view.c | 120 +++++++++++++++++++++++++++++++++++++++++++ src/viewer/text/view.h | 7 +++ 6 files changed, 150 insertions(+), 2 deletions(-) diff --git a/src/config/actions-main.inc b/src/config/actions-main.inc index 939943d..a62adcd 100644 --- a/src/config/actions-main.inc +++ b/src/config/actions-main.inc @@ -59,11 +59,15 @@ ACTION_(MAIN, "move-cursor-up", MOVE_CURSOR_UP, N__("Move cursor up"), ACTION_RE ACTION_(MAIN, "move-document-end", MOVE_DOCUMENT_END, N__("Move to the end of the document"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-document-start", MOVE_DOCUMENT_START, N__("Move to the start of the document"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-down", MOVE_LINK_DOWN, N__("Move one link down"), ACTION_REQUIRE_VIEW_STATE), +ACTION_(MAIN, "move-link-down-line", MOVE_LINK_DOWN_LINE, N__("Move to the next line with a link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-left", MOVE_LINK_LEFT, N__("Move one link left"), ACTION_REQUIRE_VIEW_STATE), +ACTION_(MAIN, "move-link-left-line", MOVE_LINK_LEFT_LINE, N__("Move one link left or to the previous link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-next", MOVE_LINK_NEXT, N__("Move to the next link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-prev", MOVE_LINK_PREV, N__("Move to the previous link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-right", MOVE_LINK_RIGHT, N__("Move one link right"), ACTION_REQUIRE_VIEW_STATE), +ACTION_(MAIN, "move-link-right-line", MOVE_LINK_RIGHT_LINE, N__("Move one link right or to the next link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-link-up", MOVE_LINK_UP, N__("Move one link up"), ACTION_REQUIRE_VIEW_STATE), +ACTION_(MAIN, "move-link-up-line", MOVE_LINK_UP_LINE, N__("Move to the previous line with a link"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-page-down", MOVE_PAGE_DOWN, N__("Move downwards by a page"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "move-page-up", MOVE_PAGE_UP, N__("Move upwards by a page"), ACTION_REQUIRE_VIEW_STATE), ACTION_(MAIN, "open-link-in-new-tab", OPEN_LINK_IN_NEW_TAB, N__("Open the current link in a new tab"), ACTION_REQUIRE_VIEW_STATE | ACTION_JUMP_TO_LINK | ACTION_REQUIRE_LINK), diff --git a/src/viewer/action.c b/src/viewer/action.c index 662dd50..4ebc99b 100644 --- a/src/viewer/action.c +++ b/src/viewer/action.c @@ -361,10 +361,18 @@ do_action(struct session *ses, enum main_action action_id, int verbose) status = move_link_down(ses, doc_view);
