Hi!

I did a quick writeup on little Edit scripts
(well basicly sam(1) scripts)
If anyone have more feel free to contribute.
Maybe someone could put them on the wiki even.

Nice idea...

Here's a simple awk bit I use in Acme for centering text (its name is
the center-line rune: ℄)

#!/bin/rc
# Center text
awk '{l=length();s=int((70-l)/2); printf "%"(s+l)"s\n",$0}'

It doesn't seem to be common practice, but I like to name editing
commands with unicode runes to save room: i.e.  ← and → for
indentation (used with code), or ⇐ and ⇒ for indentation + a reformat
(used for natural language next).  I find they serve a bit like icons.

stuff i use:

# clear whole window -- usefull with +Errors
Edit ,d 

# decrease TAB indentation of selection
Edit s,^TAB,,g


# increase TAB indentation of selection
# the ^. part ensures we indent only lines with content
# and leave empty lines undisturbed

Maybe it's time for an Acme wiki page?
Also, could you share the plumbing rules you use (for my
inspiration/learning)?

Happy Easter, folks!

1) re-format PHP's strange error mesages into standard 
FILE_PATHNAME:LINE_NUMBER


# ... called in FILE_PATHNAME on line LINE_NUMBER and defined in FILE_PATHNAME 
on line LINE_NUMBER

data matchesmultiline '.*rror.*called in ([^ ]+) on line ([0-9]+) and defined 
in ([^ ]+) on line ([0-9]+).*'
arg isfile $1
data set $file
attr add addr=$2
type is text
plumb to edit


#file / line in PHP format
data matchesmultiline '(.+) on line ([0-9]+).*'
arg isfile $1
data set $file
attr add addr=$2
type is text
plumb to edit


2) display php's function prototypes on right-click on a function name with an 
opening parenthesis. the `W' script greps a flat text file list of functions 
(with arguments and return types) and outputs to +Errors window.


type is text
data matches '[a-zA-Z_][a-zA-Z_0-9]*[(]'
plumb start W --wdir $wdir $data


* * *

a half-hearted support for displaying SQL table schema; again, `Wtable' is a 
script outputting definition of indicated table.

type is text
data matches '.*(FROM|JOIN)[ ]+([^ ]+).*'
data set $2
plumb start Wtable --wdir $wdir $data

Very nice.

Re: [9fans] Acme Edit scriptlets

[Skip Tavakkolian]

this also works:

# indent
Edit ,x/^./ y/./ c/	/

# outdent
Edit ,x/^	/ c//

Many thanks, this thread is very useful.

There is also Jason Catena's list of Edit idioms at
https://raw.github.com/catenate/acme-fonts/master/test/1/acme/Edit/sam

When editing and re-editing latex, I regularly pipe selections
through a simple-minded script called `chunk' which does most of
the work for obtaining semantic linebreaks. That goes back to a
recommendation by Kernighan in his paper `Unix for beginners' of
1974; see the quotation, comments and link at [1].



#!/usr/local/plan9/bin/rc 
# chunk up (to prepare) for semantic linebreaks

# do  not break within \cite 
# do not break within $$ math 
# break after closing parentheses ),] 
# break before an opening parentheses (,[

ssam -e 'x/(^[^%].+\n)+/  y/\\cite[^{]*{(\n|.)*}/ y/\$.*\$/
x/(([^A-Z]\.)|[,;:!?]|\)|\]) | (\(|\[)/ s/ /\n/' \ | 9 fmt -w 60
-j


For batch processing probably something more sophisticated would
be needed to leave various environments unchunked. But I don't use
it that way, and just apply it to selections where I know its use
makes sense. Usually these are areas where I have just been doing
a lot of rewriting.

There's no point in chunking up commented material, and sometimes
it is actually convenient to have a place where I can keep things
unchunked for reference.

The original chunk command in Writer's Workbench [2], for troff not
latex, was  based on a parser for English, I think. I find I don't
want that (because I write in other languages as well), and that
even in English I don't need it (because the chunking based on
interpunction is always fine with me, and where I care about the
remaining cases, I prefer to do it myself; but see [3]).

Mark.

(p9p specific)

attached is my dirty hack for automagic grepping of $% file or recursively %s 
dir or pipe.

a funky goodie:
automatically supplies `.' (dot) between arguments, so for example:

$ G some token here

becomes `grep some.token.here'

Cool.


Here's a script i use to generate case
insensitive regexes. It turns

FooBar

into

[Ff][Oo][Oo][Bb][Aa][Rr]

term% cat /bin/uncase
#!/bin/rc

exec awk '{
lower = tolower($0)
upper = toupper($0)
len = length($0)

for( i = 1 ; i <= len ; i++ )
printf "[" substr(upper, i, 1) substr(lower, i, 1) "]"
printf "\n"
}'

see also rune(1), http://9atom.org/magic/man2html/1/rune
which generalizes this idea to all of unicode (rune/case),
and also to diacritical and other markers (rune/fold; rune/unfold).
for the latter also see grep(1)'s -I flag, http://9atom.org/magic/man2html/1/grep

[9fans] Acme script request (was: Acme Edit scriptlets)

[dexen deVries]

an Edit script, or an Rc script for Acme, to close all windows which names 
start with given (literal) prefix.

use case: several files and directories of two projects open in one Acme 
instance. want to close all windows related to one of the projects, and leave 
the other project's windows open.

I took the template.awk script from werc[0] and use it in acme all the
time. I've a collection of template files beginning with

    Edit ,|tpl
    % var1=val1
    % var2=val2
    ...

I can execute line 1 to generate stuff like Makefiles, man pages, puppet
