I really have problem reading code with spaces, so I use the visual studio code editor to indent codes from spaces to tabs before I read them.
But the problem is rails has a lot of files, I have to do the same operation repetitively. So, I want to use Dir.glob to iterate over all of them and covert spaces to tabs and overwrite those files. It is a terrible idea, but still...
Currently my String#spaces_to_tabs() method looks like this:
Code
# A method that works for now...
String.define_method(:spaces_to_tabs) do
each_line.map do |x|
match = x.match(/^([^\S\t\n\r]*)/)[0]
m_len = match.length
(m_len > 0 && m_len % 2 == 0) ? ?\t * (m_len / 2) + x[m_len .. -1] : x
end.join
end
Which kind of works
Here's a test:
# Put some content that will get converted to space
content = <<~EOF << '# Hello!'
def x
'Hello World'
end
p x
module X
refine Array do
define_method(:tally2) do
uniq.reduce({}) { |h, x| h.merge!( x => count(x) ) }
end
end
end
using X
[1, 2, 3, 4, 4, 4,?a, ?b, ?a].tally2
p [1, 2, 3, 4, 4, 4,?a, ?b, ?a].tally2
\r\r\t\t # Some invalid content
EOF
puts content.spaces_to_tabs
Output:
def x
'Hello World'
end
p x
module X
refine Array do
define_method(:tally2) do
uniq.reduce({}) { |h, x| h.merge!( x => count(x) ) }
end
end
end
using X
[1, 2, 3, 4, 4, 4,?a, ?b, ?a].tally2
p [1, 2, 3, 4, 4, 4,?a, ?b, ?a].tally2
# Some invalid content
# Hello!
Currently it does not:
Affect white-spaces (\t, \r, \n) other than spaces.
Affect the output of code, only converts spaces to tabs.
I can't use my editor because:
With Dir.glob (not included in this example), I can iterate over only .rb, .js, .erb, .html, .css, and .scss files.
Also, this is slow, but I can have at most 1000 files (above extensions) with 1000 lines of code for each file, but that's max, and not too practical, I generally have < 100 files with a couple of hundred lines of code. The code can take 10 seconds, which is not a problem here, since I need to run the code once for a project...
Is there a better way to do it?
Edit
Here's the full code with globbing for converting all major files in rails:
#!/usr/bin/ruby -w
String.define_method(:bold) { "\e[1m#{self}" }
String.define_method(:spaces_to_tabs) do
each_line.map do |x|
match = x.match(/^([^\S\t\n\r]*)/)[0]
m_len = match.length
(m_len > 0 && m_len % 2 == 0) ? ?\t * (m_len / 2) + x[m_len .. -1] : x
end.join
end
GREEN = "\e[38;2;85;160;10m".freeze
BLUE = "\e[38;2;0;125;255m".freeze
TURQUOISE = "\e[38;2;60;230;180m".freeze
RESET = "\e[0m".freeze
BLINK = "\e[5m".freeze
dry_test = ARGV.any? { |x| x[/^\-(\-dry\-test|d)$/] }
puts "#{TURQUOISE.bold}:: Info:#{RESET}#{TURQUOISE} Running in Dry Test mode. Files will not be changed.#{RESET}\n\n" if dry_test
Dir.glob("{app,config,db,lib,public}/**/**.{rb,erb,js,css,scss,html}").map do |y|
if File.file?(y) && File.readable?(y)
read = IO.read(y)
converted = read.spaces_to_tabs
unless read == converted
puts "#{BLINK}#{BLUE.bold}:: Converting#{RESET}#{GREEN} indentation to tabs of #{y}#{RESET}"
IO.write(y, converted) unless dry_test
end
end
end
If this is just an intellectual exercise about tab indentation algorithms, then fine. If you really have trouble viewing the files, use Rubocop. It has configuration options that allow you to beautify the code, and the type of spaces it generates and the degree of indentation it applies. I use it with Atom and atom-beautify but I'm sure it has a plugin for VS code too. https://docs.rubocop.org/rubocop/0.86/cops_layout.html#layoutindentationconsistency
I'm using the version 7.3.3 of Notepad++.
I have this list of numbers to 1.000.000.
1
2
3
4
5
6
7
8
9
10
11
12
13
14
I want to add XML tags to these numbers like this:
<SerialNumber>
<SN>1</SN>
</SerialNumber>
<SerialNumber>
<SN>2</SN>
</SerialNumber>
<SerialNumber>
<SN>3</SN>
</SerialNumber>
<SerialNumber>
<SN>4</SN>
</SerialNumber>
So I need a regular expression to find a number ended with a \n\r, and use the number I've found with the regular expression in the text that I'm going to add.
Do you know to do that in Notepad++?
I have tried with \d{*} but it is not a valid regular expression.
Open the "Replace" menu (Search > Replace...).
And set like that :
- Find what: (\d+)[(\r)?\n]
- Replace with : <SerialNumber>\r\n <SN>$1</SN>\r\n</SerialNumber>
- Check : Search mode -> Regular expression
Then press Replace All. To even match the last number, add an empty line at the end of your file.
I hope it helps.
if we take your [1.... n] numbers in string called strData then :
var nums = strData.split("\r\n").map(function(item) {
return parseInt(item, 10);
});
var strXmlOut = nums.map(function(n) {
return "<SerialNumber><SN>" + n + "</SN></SerialNumber>";
}).join("\r\n");
and the one call version would be :
var xmlOut = strData.split("\r\n")
.map(function(item) {return parseInt(item, 10);})
.map(function(n) {return "<SerialNumber><SN>" + n + "</SN></SerialNumber>";})
.join("\r\n");
I have a file containing numbers like
1, 2, 3
4, 5
6, 7, 8, 9,10,11
12,13,14,15,16
...
I want to create a CSV file by padding each line such that there are 6 values separated by 5 commas, so I need to add to each line an appropriate number of ",0". It shall look like
1, 2, 3, 0, 0, 0
4, 5, 0, 0, 0, 0
6, 7, 8, 9,10,11
12,13,14,15,16, 0
...
How would I do this with VIM?
Can I count the number of "," in a line with regular expressions and add the correct number of ",0" to each line with the substitute s command?
You can achieve that by typing this command:
:g/^/ s/^.*$/&,0,0,0,0,0,0/ | normal! 6f,D
You can add six zeros in all lines first, irrespective of how many numbers they have and then, you can delete everything from sixth comma till end in every line.
To insert them,
:1,$ normal! i,0,0,0,0,0,0
To delete from sixth comma till end,
:1,$normal! ^6f,D
^ moves to first character in line(which is obviously a number here)
6f, finds comma six times
D delete from cursor to end of line
Example:
Original
1,2,
3,6,7,0,0,0
4,5,6
11,12,13
After adding six zeroes,
1,2,0,0,0,0,0,0
3,6,7,0,0,0,0,0,0,0,0,0
4,5,6,0,0,0,0,0,0
11,12,13,0,0,0,0,0,0
After removing from six comma to end of line
1,2,0,0,0,0,0
3,6,7,0,0,0,0
4,5,6,0,0,0,0
11,12,13,0,0,0
With perl:
perl -lpe '$_ .= ",0" x (5 - tr/,//)' file.txt
With awk:
awk -v FS=, -v OFS=, '{ for(i = NF+1; i <= 6; i++) $i = 0 } 1' file.txt
With sed:
sed ':b /^\([^,]*,\)\{5\}/ b; { s/$/,0/; b b }' file.txt
As far as how to do this from inside Vim, you can also pipe text through external programs and it will replace the input with the output. That's an easy way to leverage sorting, deduping, grep-based filtering, etc, or some of Sato's suggestions. So, if you have a script called standardize_commas.py, try selecting your block with visual line mode (shift+v then select), and then typing something like :! python /tmp/standardize_commas.py. It should prepend a little bit to that string indicating that the command will run on the currently selected lines.
FYI, this was my /tmp/standardize_commas.py script:
import sys
max_width = 0
rows = []
for line in sys.stdin:
line = line.strip()
existing_vals = line.split(",")
rows.append(existing_vals)
max_width = max(max_width, len(existing_vals))
for row in rows:
zeros_needed = max_width - len(row)
full_values = row + ["0"] * zeros_needed
print ",".join(full_values)
I have a BigDecimal variable that contains number with minus(-) and not. I want to put static text that should be match with this conditions:
If $V{saldo} contains minus (-) value The static text will show "Rugi"
If $V {saldo} doesnt's contain minus(-) value the static text will show "Laba"
For example, if $V{saldo} = -250000 then the static text should be "Rugi", and if $V{saldo} = 400000 then the static text should be "Laba"
Try using this if-else construct:
$V{saldo}.intValue() < 0 ? "Rugi" : "Laba"
Please see this SO post for more information.
First Check for ZERO then apply your logic
$V{saldo}.$V{saldo} != 0.0 ? ($V{saldo}.intValue() < 0 ? "Rugi" : "Laba"): "Zero"
I have a AWK script to write specific values matching with specific pattern to a .csv file.
The code is as follows:
BEGIN{print "Query Start,Query End, Target Start, Target End,Score, E,P,GC"}
/^\>g/ { Query=$0 }
/Query =/{
split($0,a," ")
query_start=a[3]
query_end=a[5]
query_end=gsub(/,/,"",query_end)
target_start=a[8]
target_end=a[10]
}
/Score =/{
split($0,a," ")
score=a[3]
score=gsub(/,/,"",score)
e=a[6]
e=gsub(/,/,"",e)
p=a[9]
p=gsub(/,/,"",p)
gc=a[12]
printf("%s,%s,%s,%s,%s,%s,%s,%s\n",query_start, query_end,target_start,target_end,score,e,p,gc)
}
The input file is as follows:
>gi|ABCDEF|
Plus strand results:
Query = 100 - 231, Target = 100 - 172
Score = 20.92, E = 0.01984, P = 4.309e-08, GC = 51
But I received the output in a .csv file as provided below:
100 0 100 172 0 0 0 51
The program failed to copy the values of:
Query end
Score
E
P
(Note: all the failed values are present before comma (,))
Any help to obtain the right output will be great.
Best regards,
Amit
As #Jidder mentioned, you don't need to call split() and as #jaypal mentioned you're using gsub() incorrectly, but also you don't need to call gsub() at all if you just include , in your FS.
Try this:
BEGIN {
FS = "[[:space:],]+"
OFS = ","
print "Query Start","Query End","Target Start","Target End","Score","E","P","GC"
}
/^\>g/ { Query=$0 }
/Query =/ {
query_start=$4
query_end=$6
target_start=$9
target_end=$11
}
/Score =/ {
score=$4
e=$7
p=$10
gc=$13
print query_start,query_end,target_start,target_end,score,e,p,gc
}
That work? Note the field numbers are bumped out by 1 because when you don't use the default FS awk no longer skips leading white space so there's an empty field before the white space in your input.
Obviously, you are not using your Query variable so the line that populates it is redundant.
