I have a bunch of SQL scripts that do this:
COALESCE([18], 0),COALESCE([19], 0),COALESCE([20], 0),COALESCE([21], 0) ect
Is there a way to use regex to update them to do this:
COALESCE([18], 0) as [18], COALESCE([19], 0) as [19], COALESCE([20], 0) as [20], COALESCE([21], 0) as [21]
Find:
[^()]+\(\[(\d+)\][^)]+\)
Replace:
$0 AS [$1]
Demo:
Debuggex Demo
(.*?(\[\d+\]).*?\))
This will work as well.
See demo.

I am having trouble creating a data frame with the following data:
Force (N) microstrain1 microstrain2 microstrain3 microstrain4 microstrain5
24.838 9.689 -20.299 19.785 15.601 -7.681
49.691 22.610 -40.797 41.304 32.200 -15.332
75.309 33.357 -61.678 62.512 48.726 -22.422
97.227 41.944 -80.524 81.011 62.266 -30.228
121.641 52.692 -100.775 100.703 77.248 -36.884
Every time I try to use a delimiter I get the following message:
/Users/macbookpro/PycharmProjects/Projects/Lab_3/Bending.py:5: ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex); you can avoid this warning by specifying engine='python'.
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt',delimiter=' ')
Did you try the python engine instead of the c engine?:
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt', delimiter=' ', engine='python')

I'm looking for a Julia function which, when applied to a module name, lists the functions available through the module.
Basically, I don't want to scour through source code and I've noticed that the documentation for many modules usually doesn't have everything.
names works, mostly:
module MyMod
test() = 3
foo() = 4
end
names(MyMod, true)
gives me
4-element Array{Symbol,1}:
:eval
:test
:foo
:MyMod
Just need to strip out the module name and eval
Expanding on the previous answer slightly, the following seems to work:
function module_functions(modname)
list = Symbol[]
for nm in names(modname)
typeof(eval(nm)) == Function && push!(list,nm)
end
return list
end
Example:
using PyPlot
module_functions(PyPlot)
produces the following output in the REPL:
165-element Array{Symbol,1}:
:contourf
:over
:xticks
:ion
:flag
:summer
:stackplot
:tricontourf
:minorticks_on
:gray
:savefig
:errorbar
:box
:figure
:vlines
:subplot_tool
:jet
⋮
:locator_params
:imshow
:pie
:sci
:axhline
:streamplot
:hist2d
:copper
:text3D
:Axes3D
:loglog
:zticks
:hexbin
:pcolor
:semilogy
:thetagrids

Here is my code:
- (CGFloat)layoutManager:(NSLayoutManager *)layoutManager lineSpacingAfterGlyphAtIndex: (NSUInteger)glyphIndex withProposedLineFragmentRect:(CGRect)rect
{
return 20;
}
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex:glyphIndex withProposedLineFragmentRect:rect)
20
end
Start here: http://www.rubymotion.com/developer-center/guides/getting-started/
Should be something like this:
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex: nil, withProposedLineFragmentRect: nil)
return 20.0
end
Check the repo for examples.
Also, that method should return a float, not an int.

}
if( $c[$p]['progressbar']['enable'] ) {
$c[$p]['side'] = draw_progressbar( reset( array_keys( $c[$p]['reasons']['data'] ) ), $all );
}
Whats Wrong Here ??
You have a closing bracket on line 1.
Assuming PHP this error means that reset() expects a variable and not the result of another function (like array_keys() in your example.
See the function signature: mixed reset ( array &$array )
This means that for your problem you need to store the array in a variable:
$tmp = array_keys( $c[$p]['reasons']['data'] );
$c[$p]['side'] = draw_progressbar( reset( $tmp ), $all );

I need to update 50K records by changing the status of comments (turning read & read/write into disabled) and want to make sure my SQL statement is correct:
$query = "UPDATE node.nid AS nid, node.comment AS node_comment, node.type AS node_type
SET node.comment = '0'
WHERE (node.type in ('article', 'blog', 'event'))
AND (node.comment in ('1','2'))";
$total = 0;
$count = 0;
while ($query_result = db_query($query)){
$count++;
$total++;
if($count>200){
$count = 0;
sleep(300);
}
}
echo "Updated records:" . $total;
I added a periodic pause in there so it doesn't kill the server. Does this look ok?
I changed the UPDATE to just node node and that worked.
