From b8c767354ec847e1415550b8002430c71e99ed47 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?P=C5=99emysl=20Eric=20Janouch?= Date: Thu, 1 Oct 2020 11:54:01 +0200 Subject: Show external command line if appropriate Since I'm already dealing with the fish shell. All of our supported shells seem to handle cursor position in Unicode (wide character) codepoints. It was easiest and most straight-forward to pass the data through yet-unused program arguments. The cursor position is marked by a Unicode glyph equivalent to ACS_DIAMOND, although ncurses doesn't get a chance to make any ACS translation. --- README.adoc | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'README.adoc') diff --git a/README.adoc b/README.adoc index 18f922a..dd4e583 100644 --- a/README.adoc +++ b/README.adoc @@ -55,7 +55,7 @@ To start using this navigator, put the following in your '.zshrc': ---- sdn-navigate () { # ... possibly zle-line-init - while eval "`sdn`"; do + while eval "`sdn "$BUFFER" "$CURSOR"`"; do [ -z "$cd" ] || cd "$cd" [ -z "$insert" ] || LBUFFER="$LBUFFER$insert " [ -z "$helper" ] && break @@ -74,7 +74,9 @@ To start using this navigator, put the following in your 'config.fish': ---- function sdn-navigate set --local IFS - while eval (sdn | string replace -ar '^(.*?)=' 'set --$1 ') + set --local buffer (commandline) + set --local cursor (commandline --cursor) + while eval (sdn $buffer $cursor | string replace -ar '^(.*?)=' 'set --$1 ') test -z "$cd" || cd "$cd" test -z "$insert" || commandline --insert "$insert " test -z "$helper" && break @@ -96,7 +98,7 @@ sdn-navigate () { SDN_L=$READLINE_LINE SDN_P=$READLINE_POINT READLINE_LINE= - while eval "`sdn`"; do + while eval "`sdn "$SDN_L" "$SDN_P"`"; do [[ -z "$cd" ]] || cd "$cd" [[ -z "$insert" ]] || { SDN_L="${SDN_L:0:$SDN_P}$insert ${SDN_L:$SDN_P}" @@ -129,6 +131,7 @@ cursor 231 202 bar 16 255 ul cwd bold input +cmdline 102 ....
