Grep Alternation and Backreferences

[Mike Conley]

No doubt someone has covered this before, but I can't find a reference to 
it, and so ...

If I have a string that may consist of, say, a first name and a last name 
followed by another occurrance of the first name and last name, possibly in 
a different order, and I want to match that entire string, I would like to 
do something such as:-

(Joe|Bloggs){2}\1

If my string is 

JoeBloggsBloggsJoe

it would be nice if the \1 were to match all of the substring 'BloggsJoe'; 
i.e., the backreference to the captured alternation would include the 
entire captured alternation. But, instead, it seems that \1 matches only 
'Bloggs', so the resulting match is 

JoeBloggsBloggs

rather than

JoeBloggsBloggsJoe

Is there a way to accomplish what I want to do? Or am I out of luck? Or is 
it a bug?

Cheers

-mike

Grep to change initial character matching case?

[Mike Conley]

I don't think there's a way to do this in grep, but before I go and try to 
twist my brain around Perl, I thought I would ask:

I often want to do a search and replace on a particular word, which may be 
part of one or more identifiers or just part of text, and replace it with a 
different word. But sometimes the word might be capitalised, and other 
times not. 

For example, say I wanted to change the word 'file' to 'plot'. This word 
might occur in a comment ('If the file has been loaded ...') or in variable 
or function identifiers (fileList, FileType, pFileName, files, etc.).

If I want to do a search and replace and keep the initial character's case 
the same, I have to do two passes, and pay close attention to which one I'm 
changing (upper or lower case), so the thing is very time-consuming and 
requires a lot more attention than it ought to.

Is there a way to specify that the grep replacement should match the case 
of the character? I'm thinking of something like 

Find: (F|f)ile
Replace: \@1(p)lot

where '\@1(p)' means replace subpattern 1 with 'p' matching the case of the 
character. 

Or, actually, even better and more flexibly, this would work:

Replace: \@1(P|p)lot

where '@1' means replace the first subpattern with the term in the alternation 
list that corresponds to the one matched. With this, we could even do 
something like this:

   Find: (red|green|blue)
   Replace: \@(cyan|magenta|yellow)

Is there such a beast already? I'm not seeing it. Or maybe it's just a lot 
more complicated than this.

Get Display Font?

[Mike Conley]

Anyone have any idea why, when I do this

*tell **application* BBEdit

*set* p *to* properties *of* *front* *text window*
*log* p

*end **tell*

*
*
I see (amongst a lot of other stuff)

display font:missing value


Basically, I'm trying to do a 'set x to display font of front text window', 
and it always fails, even after I've just done a 'set display font of front 
text window to thingy' and the font has visibly changed.

You know, I really would like to know why it is that people insist on

them to Bare Bones technical support. I mean, as someone who has to deal 
with technical support issues myself, I'm quite curious. Is it just a 
mistrust of the official channels? Is it that people send in reports and 
get no response and are thus frustrated? Is it just plain ignorance? Is it 
the fact that the Google Groups facility doesn't make it easy to shove the 
'contact technical support' notice in people's faces?

And I wonder whether BB have simply given up and now consider this forum 
(and the others) as simply an alternative to the tech support e-mail 
address. I mean, I would be sorely tempted to do so -- at least if any 
significant fraction of my bug reports came through this channel rather 
than the recommended one.

Anyway. Just wondering, really.

Re: Possible, worthwhile to port Solarized for use with BBEdit?

[Mike Conley]

 The problem doing this in BBEdit is not the lack of inversion, it's
 the restriction to only two background colours in the theme.

Well, no, because you can't choose a text selection colour that's dark
or close to the text colour, or the text will not be legible when
selected. And given that there are many possible text colours and only
one selection colour, there's no way to choose a selection colour that
works with every possible text colour. The only way to make that work
is to change the text colour if necessary when it's highlighted, and
this is typically done by inversion (though it needn't be; other
methods could be used). I think one important thing to keep in mind is
that one shouldn't simply change the selected text colour under all
circumstances; as I noted earlier, it depends on the relative
intensities and hues of the text and highlight colours.

Re: Possible, worthwhile to port Solarized for use with BBEdit?

[Mike Conley]

I think the real problem with highlighting is that BBEdit doesn't
alter the text colour when it's highlighted, in the manner of some of
the apps to which Solarized colours are applied. If it inverted
highlighted text when the highlight colour is sufficiently
'dark' (e.g., when the difference between the luminance of the text
and that of the highlight is sufficiently small), then it would work
at least as well as in the examples on the Solarized Web site.

I've already submitted that as a feature request; we'll see whether it
bubbles up to the top of somebody's queue.

Failing that, yes, the only solution is to use a less saturated,
lighter highlight colour.

Re: markup color

Monaco 9 pt (the One True Programmer's Font)
Keywords are Grape
Strings are Maraschino
Comments are Alumin(i)um
Numeric constants are RGB {51,102,153}
Predefined names are RGB {17,129,183}
Highlight line colour is RGB {245,243,206}

My background colour is based on a series of books that I had as a
child -- I think they were called 'Easy Eye' books, and they were
reprints of classics (Jules Verne, Robert Louis Stevenson, etc.). The
paper was tinted a light green colour, as this was thought to be
easier on the eye than the higher contrast of black on white. The
colour is CMYK {5, 2, 3, 0}.

Re: how to i disable the help keyboard shortcut near the backspace key?

[Mike Conley]

I think you're talking about accidentally hitting the Help key --
which is right next to the backspace key on an extended keyboard,
which used to drive me nuts, too.

The solution is to remap the Help key to something else in the Menus
section of BBEdit's Preferences. I set mine to Window  Bring All to
Front, which is pretty innocuous, and doesn't affect anything I've
typed.

Re: Mac OSX Wants to Open All my Text Files in Terminal?

LaunchServices and file association under Leopard is hopelessly

and, yes, I reset LaunchServices every now and then, and, yes, this
works for a few reboot cycles, but, no, it doesn't stick, and, yes,
I'm thoroughly sick to death of it.

This is a known issue, and Apple has so far refused to fix it; the fix
went into Snow Leopard, but has not been back-ported. File a bug
report; maybe with enough complaints they'll eventually decide it's
worth fixing.

Re: Wrapping C style comments

[Mike Conley]

I'll just chime in with my own personal prejudice and point out that I
truly loath any style of comments that insists on putting something at
the beginning of each line (*, //, whatever) of comment text. It's
cluttered, makes it next to impossible to edit the text by hand, and
requires extra effort on the part of editor software to handle
correctly to do automatic reformatting.

Syntax-colouring is available, which serves to highlight comments. All
that's needed is a /* before the first line and a */ afterward, and
there you go. Simple and clean.

Assign a keyboard shortcut (mine's command-option-\) to Text  Hard
Wrap, and reformatting is straightforward.

In fact, I even have a script to reformat silly //-delimited comments
and convert them to my desired format. Use at your own risk.

Script to open document in additional window?

[Mike Conley]

Okay, as usual with AppleScript, I can't seem to figure out how to do
something that should be simple enough: I want to write a script that
does the Open in Additional Window command, so that I can easily
create a second view into my document without having to open the
drawer, etc. Recording the steps doesn't seem to work, from which I
gather that Open in Additional Window is not a scriptable command at
the moment; fine, but it seems that I ought to be able to do it some
other way. I've tried the following:

tell application BBEdit
activate
set docFile to file of text window 1
open docFile opening in new_window
end tell

which seems straightforward enough, but this doesn't work; it simply
brings the existing window to the front. I've also tried

tell application BBEdit
activate
set docFile to file of text window 1
make new text window
open docFile opening in text window 1
end tell

but that doesn't work, either. Anyone have more patience and savvy
about this than I do?

Re: Script to open document in additional window?

[Mike Conley]

 If you're not committed to using AppleScript for this you could go to the
 Menus bit in Preferences and assign a key equivalent for this.

Y'know, as it turns out, I had, in fact, assigned a key equivalent to
this already, but had forgotten. Thanks for reminding me.

Nonetheless, it would still be nice to do an AppleScript, because I
would have it create the new window and align it beside the original,
with the same dimensions, since that's what I would do every time
anyway. So the question still stands.
