Is there a better smart-home macro? preferable a smart-home macro that can toggle between line-begin and text-begin.

I never got an answer on this issue.

If any of you are using smart home, what way did you define it?

I don't use such a macro, but I imagine you can get it to work basically however you want. How is that, exactly?

what if you do:

• move to beginning of line
• search ahead (w/ regexp) for `[^ \t]`
• move left

that should do what you want, as far as I cant tell.

Thanks Jacob, this works much better than what I had before :-)

Still, any ideas how to jump between beginning of line and beginning of text ? (aka. smart-home in the pc world)

Here's a command that will do the trick. If the cursor is at the beginning of the line it gets moved to the first non-whitespace character. Otherwise it gets moved to the beginning of the line.

Input: Selected Text or Line Output: Insert as Snippet

----- Cut Here ----- #! /usr/bin/perl

$line = $ENV{'TM_CURRENT_LINE'}; $column = $ENV{'TM_COLUMN_NUMBER'}; $whitespace = '';

if ($column == 1) { # Chop leading whitespace from the line and # place it into its own variable. $line =~ s/^([ \t]*)//; $whitespace = $1; }

# Escape anything in the line that might be mistaken # as a snippet token. $line =~ s/([$\`])/\\1/g;

# Print the line as a snippet. The cursor will be # placed at the ${1} token. printf '%s${1}%s', $whitespace, $line;

Ah, nice.

I have modified it slightly so that it first jump's to the the text-beginning and afterwards to the line-beginning.

#! /usr/bin/ruby line = ENV['TM_CURRENT_LINE'] index = ENV['TM_LINE_INDEX'].to_i

# extract leading whitespace remain = line.sub(/(^[ \t]*)/, '') whitespace = $1

if index == whitespace.size whitespace = '' else line = remain end

# place cursor print "#{whitespace}${1}#{line}"

Excellent... one issue though, it seems that it trims some of the line with it on certain cases. I use smarty templates in some of my work, and some lines have text like:

{$var|modifier}

after using the command, $var disappears (everything before the pipe, not including the left curly brace)

When Simon translated Steve's Perl code into Ruby, he missed out a crucial line:

# Escape anything in the line that might be mistaken # as a snippet token. $line =~ s/([$\`])/\\1/g; In Ruby, I think that would be:

line.gsub!(/([$\`])/){"\#$1"};

Yes indeed. Thanks

problem: when text is selected and invoking this smart-home-command, then the selected text is erased.

Any ideas how to avoid this?

You could record a macro that selects the current line (apple-L) then invokes the command.

Apple-SHIFT-L, sorry!

Also, the line of Ruby code I posted needs to be changed to

line = line.gsub(/([$\`])/){"\#$1"}

otherwise it gives an error when a) the cursor is already at the end of the initial whitespace on the line, and b) the line contains a special character ($, , or `).

Use a macro to deselect the text then execute the command. I have a "Select Nothing" macro that is:

moveRightAndModifySelection: moveLeft:

(Record it by typing "shift-Right" then "Left".) This places the cursor at the beginning of the selection then clears the selection. Just record a macro with those strokes and the "Smart Home" command, save the macro, and bind it to the Home key.

(As an aside... I'm surprised I can't find a "clearSelection:" action. Anyone know of one that's better than this hack?)

It would, of course, be better to just move the cursor without modifying the selection. Unfortunately, the way commands are implemented there's no way to simply move the cursor without inserting text as a snippet. Any selection is going to be replaced by that insertion.

Which brings us to another problem with this command. Since it's actually doing an insert operation the buffer gets marked as modified, even if no other changes have been made. I'd love to have a way to simply move the cursor without the insert operation. Here's to a richer API in 2.0!
