I have two CSS files where most of the whitespace have been removed. I wonder whether there's a way to get a meaningful diff out of them.
Run each file through a CSS prettifier, and then diff them the normal way.
A quick google search turned up this online prettifier: http://procssor.com/
Do a search and replace through the css file and insert a new line after every '{', '}' and ';' character. Then, you can use ordinary diff to compare them.
Use Pretty Diff. That tool is a language aware diff tool, so trivial things like white space and comments are filtered out as false positives.

I have the following in my .zshrc:
setopt PROMPT_SUBST
precmd(){
echo""
LEFT="$fg[cyan]$USERNAME#$HOST $fg[green]$PWD"
RIGHT="$fg[yellow]$(date +%I:%M\ %P)"
RIGHTWIDTH=$(($COLUMNS-${#LEFT}))
echo $LEFT${(l:$RIGHTWIDTH:)RIGHT}
}
PROMPT="$ "
This gives me the following screenshot
The time part on the right is always not going all the way to the edge of the terminal, even when resized. I think this is due to the $(date +%I:%M\ %P) Anyone know how to fix this?
EDIT: Zoomed in screenshot
While your idea is commendable, the problem you suffer from is that your LEFT and RIGHT contains ANSI escape sequences (for colors), which should be zero-width characters, but are nevertheless counted toward the length of a string if you naively use $#name, or ${(l:expr:)name}.
Also, as a matter of style, you're better off using Zsh's builtin prompt expansion, which wraps a lot of common things people may want to see in their prompts in short percent escape sequences. In particular, there are builtin sequences for colors, so you don't need to rely on nonstandard $fg[blah].
Below is an approximate of your prompt written in my preferred coding style... Not exactly, I made everything super verbose so as to be understandable (hopefully). The lengths of left and right preprompts are calculated after stripping the escape sequences for colors and performing prompt expansion, which gives the correct display length (I can't possibly whip that up in minutes; I ripped the expression off pure).
precmd(){
local preprompt_left="%F{cyan}%n#%m %F{green}%~"
local preprompt_right="%F{yellow}%D{%I:%M %p}%f"
local preprompt_left_length=${#${(S%%)preprompt_left//(\%([KF1]|)\{*\}|\%[Bbkf])}}
local preprompt_right_length=${#${(S%%)preprompt_right//(\%([KF1]|)\{*\}|\%[Bbkf])}}
local num_filler_spaces=$((COLUMNS - preprompt_left_length - preprompt_right_length))
print -Pr $'\n'"$preprompt_left${(l:$num_filler_spaces:)}$preprompt_right"
}
PROMPT="$ "
Edit: In some terminal emulators, printing exactly $COLUMN characters might wrap the line. In that case, replace the appropriate line with
local num_filler_spaces=$((COLUMNS - preprompt_left_length - preprompt_right_length - 1))
End of edit.
This is very customizable, because you can put almost anything in preprompt_left and preprompt_right and still get the correct lengths — just remember to use prompt escape sequence for zero width sequences, e.g., %F{}%f for colors, %B%b for bold, etc. Again, read the docs on prompt expansion: http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html.
Note: You might notice that %D{%I:%M %p} expands to things like 11:35 PM. That's because I would like to use %P to get pm, but not every implementation of strftime supports %P. Worst case scenario: if you really want lowercase but %P is not supported, use your original command subsitution $(date +'%I:%M %P').
Also, I'm using %~ instead of %/, so you'll get ~/Desktop instead of /c/Users/johndoe/Desktop. Some like it, some don't. However, as I said, this is easily customizable.
This is a formatting issue that's been bugging me. I like to use leading commas in my grouped variable declarations, ie:
var something = true
, anotherVar = false
Debate about whether that's good or not, aside... I've noticed when I cut and paste this in the Atom editor it drops the leading tab /spacing so that the comma is directly under the "v" in var and the variable names are misaligned.
Might seem trivial but it causes my OCD to flare up. Are there any known workarounds? Thanks!
Found a workaround:
Settings > Language Javascript (Package) > Uncheck Auto Indent On Paste
Will report back if there's any adverse consequences, so far seems to work as expected.
I'm having trouble reading this table into R:
http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt
I tried all of the following:
read.table("http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt")
read.table("http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt",skip=7,header=FALSE)
read.table("http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt",skip=8,header=FALSE)
read.table("http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt",skip=10,header=FALSE)
If I tell it that the separator is a tab, i get the wrong table:
d = read.table(file="http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt",header=FALSE,skip=7,sep="\t")
the only thing that seems to work is readLines. but then i don't know how to get a data.frame out of each line.
d =readLines("http://www.census.gov/popest/about/geo/state_geocodes_v2012.txt")
any suggestions? thanks.
I agree that read.fwf will work, once you've worked out the widths.
But, Yeah -- I just hate people who allow whitespace inside elements (e.g. "SouthDakota" ) . One other thing you can do is edit the source text file, replacing {2,N} spaces with a tab. That will leave the state names as-is but give you a workable delimiter.
I have a csv, and each line reads as follows:
"http://www.videourl.com/video,video title,video duration,thumbnail,<iframe src=""http://embed.videourl.com/video"" frameborder=0 width=510 height=400 scrolling=no> </iframe>,tag 1,tag 2",,,,,,,,,,,,,,,,,,,,,,,,,,
Is there a program I can use to clean this up? I'm trying to import it to wordpress and map it to current fields, but it isn't functioning properly. Any suggestions?
Just use search and replace in this case. remove the commas at the end and then replace the remaining commas with ",".
Should anyone else have the same issue. Know that this solution will only work with data much like the example giving. If data has a lot of text and there are commas within the text that need kept. Then search replacing comma will not work. Using regex would be the next option and that can be done in Notepad ++
However I think the regex pattern depends on the data so not much point creating an example.
PHP could be used to explode each line also. Remove values that match a regex out of many i.e. URL, money. Then what is left could be (depending on the data again) just a block of text. That approach may not work if there are two or more columns with a lot of text
for some reason, I cannot download the r xml package at work. I have an xml file that has contents like this:
x<-read.table("info.xml")
x
</name></content></item><item id="id-123"><content><name>
</name></content></item><item id="id-456"><content><name>
</name></content></item><item id="id-5559"><content><name>
I need to pick values that start with id and - and the numbers like
id-123, id-456 id-5559, etc
tried this:
str_extract_all(x, "id-[0-9]")
but is only printing id-1, I really need help very quick. Any ideas?
str_extract_all(x, "id-[0-9]+")
The regular expression "id-[0-9]" is missing a "+" at the end.
There may be more issues, but that one jumps out.
