Print Current Line number in Sublime - sublimetext

Is there a key-combination to print out the current line number?
This would be really useful in conjunction with the multiple selection method (cmd+D).

I don't think there is a key binding or command do what you want, but I'm I'm unsure what it is that you mean by printing current line numbers in Sublime.
This is probably not at all what you want, but I'll leave it here for a while before I delete it. It might help you write a custom command for what you want.
Command
import sublime_plugin
class InsertLineNumberCommand(sublime_plugin.TextCommand):
def run(self, edit):
for sel in self.view.sel():
line_begin = self.view.rowcol(sel.begin())[0]
line_end = self.view.rowcol(sel.end())[0]
self.view.insert(edit, sel.end(), str(line_begin + 1))
Key Binding:
{
"keys": ["ctrl+i"],
"command": "insert_line_number"
}
Usage
1:
2: fizz|buzz
3:
Where | is the cursor, pressing ctrl+i:
1:
2: fizz2|buzz
3:
With a multiple selection:
1:
2: |fizz|2
3: buzz
4:
5: |fizz|5
6: buzz
7:

How can I use the ruamel.yaml rtsc mode?

I've been working on creating a YAML re-formatter based on ruamel.yaml (which you can see here).
I'm currently using version 0.17.20.
Cleaning up comments and whitespace has been difficult. I want to:
ensure there is only one space before the # for EOL comments
align full line comments with the key or item immediately following
remove duplicate blank lines so there is at most one blank line
To get closer to achieving that, I have a custom Emitter class where I extend write_comment to adjust the comments just before writing with super().write_comment(...). However, the Emitter does not know about which key or item comes next because comments are generally attached as post comments.
As I've studied the ruamel.yaml code to figure out how to do this, I found the rtsc mode (Round Trip Split Comments) which looks fantastic because it separates EOLComment, BlankLineComment and FullLineComment instead of lumping them together.
From what I can tell, the Parser and Scanner have been adjusted to capture the comments. So, loading is (mostly?) implemented with this "NEWCMNT" implementation. But Emitter.write_comment expects CommentToken instead of comment line numbers, so dumping does not work yet.
If I update my Emitter.write_comment method, is that enough to finish dumping? Or what else might be necessary? In one of my tries, I ran into a sys.exit in ScannedComments.assign_eol() - what else is needed to finish that?
PS: I wouldn't normally ask how to collaborate on StackOverflow, but this is not a bug report or a feature request, and I'm trying/failing to use a new (undocumented) feature, so I'm filing this here instead of sourceforge.
rtsc is work in progress cq work started but unfinished. It's internals will almost certainly change.
Two of the three points you indicate can relatively easy be implemented:
set the column of each comment to 0 ( by recursively going over a loaded data structure similar to here ) if the column is before the position of the end of the value on a line, you'll get one space between the value and the column
at the same time doing the recursion in the previous point. Take each comment value and do something like:
value = '\n'.join(line.strip() for line in value.splitlines()
while '\n\n\n' in value:
value = value.replace('\n\n\n', '\n\n')
The indentation to the following element is difficult, depends on the
data structure etc. Given that these are full line comments, I suggest
you do some postprocessing of the YAML document you generate:
find a full line comment, gather full line comments until next line is
not full line comment (i.e. some "real" YAML). Since full line comments
are in column[0] if the previous stuff is applied, you don't have to
track if you are in a (multi-line) literal or folded scalar string where
one of the lines happens to start with #
determine number of spaces
before real YAML and apply these to the full line comments.

python regex specific blocks of text from large text file

I'm new to python and this site so thank-you in advance for your... understanding. This is my first attempt at a python script.
I'm having what I think is a performance issue trying to solve this problem which is causing me to not get any data back.
This code works on a small text file of a couple pages but when I try to use it on my 35MB real data text file it just hits the CPU and hasn't returned any data (>24 hours now).
Here's a snippet of the real data from the 35MB text file:
D)dddld
d00d90d
dd
ddd
vsddfgsdfgsf
dfsdfdsf
aAAAAAa
221546
29806916295

What's your cat doing?
fs:/mod/umbapp/umb/sentbox/10955.pdu
2013:10:4:22:10:15:4
aaa
aaa
aaaaa
What I'm trying to copy into a new file:
29806916295
Meowing
fs:/mod/umbapp/umb/sentbox/221546.pdu
2013:10:4:22:11:31:4
29806916295
What's your cat doing?
fs:/mod/umbapp/umb/sentbox/10955.pdu
2013:10:4:22:10:15:4
My Python code is:
import re
with open('testdata.txt') as myfile:
content = myfile.read()
text = re.search(r'\d{11}.*\n.*\n.*(\d{4})\D+(\d{2})\D+(\d{1})\D+(\d{2})\D+(\d{2})\D+\d{2}\D+\d{1}', content, re.DOTALL).group()
with open("result.txt", "w") as myfile2:
myfile2.write(text)
Regex isn't the fastest way to search a string. You also compounded the problem by having a very big string (35MB). Reading an entire file into memory is generally not recommended because you may run into memory issues.
Judging from your regex pattern, it seems like you want to capture 4-line groups that start with an 11-digit string and end with some time-line string. Try this code:
import re
start_pattern = re.compile(r'^\d{11}$')
end_pattern = re.compile(r'^\d{4}\D+\d{2}\D+\d{1}\D+\d{2}\D+\d{2}\D+\d{2}\D+\d{1}$')
capturing = 0
capture = ''
with open('output.txt', 'w') as output_file:
with open('input.txt', 'r') as input_file:
for line in input_file:
if capturing > 0 and capturing <= 4:
capturing += 1
capture += line
elif start_pattern.match(line):
capturing = 1
capture = line
if capturing == 4:
if end_pattern.match(line):
output_file.write(capture + '\n')
else:
capturing = 0
It iterates over the input file, line by line. If it finds a line matching the start_pattern, it will read in 3 more. If the 4th line matches the end_pattern, it will write the whole group to the output file.

Converting a multi line string to an array in Ruby using line breaks as delimiters

I would like to turn this string
"P07091 MMCNEFFEG
P06870 IVGGWECEQHS
SP0A8M0 VVPVADVLQGR
P01019 VIHNESTCEQ"
into an array that looks like in ruby.
["P07091 MMCNEFFEG", "P06870 IVGGWECEQHS", "SP0A8M0 VVPVADVLQGR", "P01019 VIHNESTCEQ"]
using split doesn't return what I would like because of the line breaks.
This is one way to deal with blank lines:
string.split(/\n+/)
For example,
string = "P07091 MMCNEFFEG
P06870 IVGGWECEQHS
SP0A8M0 VVPVADVLQGR
P01019 VIHNESTCEQ"
string.split(/\n+/)
#=> ["P07091 MMCNEFFEG", "P06870 IVGGWECEQHS",
# "SP0A8M0 VVPVADVLQGR", "P01019 VIHNESTCEQ"]
To accommodate files created under Windows (having line terminators \r\n) replace the regular expression with /(?:\r?\n)+/.
I like to use this as a pretty generic method for handling newlines and returns:
lines = string.split(/\n+|\r+/).reject(&:empty?)
string = "P07091 MMCNEFFEG
P06870 IVGGWECEQHS
SP0A8M0 VVPVADVLQGR
P01019 VIHNESTCEQ"
Using CSV::parse
require 'csv'
CSV.parse(string).flatten
# => ["P07091 MMCNEFFEG", "P06870 IVGGWECEQHS", "SP0A8M0 VVPVADVLQGR", "P01019 VIHNESTCEQ"]
Another way using String#each_line :-
ar = []
string.each_line { |line| ar << line.strip unless line == "\n" }
ar # => ["P07091 MMCNEFFEG", "P06870 IVGGWECEQHS", "SP0A8M0 VVPVADVLQGR", "P01019 VIHNESTCEQ"]
Building off of #Martin's answer:
lines = string.split("\n").reject(&:blank?)
That'll give you only the lines that are valued
Split can take a parameter in the form of the character to use to split, so you can do:
lines = string.split("\n")
I think it should be noted that in some situations, line breaks can include not only newlines (\n) but also carriage returns (\r) and that there could potentially be any combination or quantity thereof. Let's take the following string for example:
str = "Useful Line 1 ....
Useful Line 2
Useful Line 3
Useful Line 4... \n
Useful Line 5\r \n
Useful Line 6\n\r
Useful Line 7\n\r\n\r
Useful Line 8 \r\n\r\n
Useful Line 9\r\r\r Useful Line 10\n\n\n\n\nUseful Line 11 \r Useful Line 12"
To deal with all instances of \n and \r, I would do the following to replace all instances of \r with \n using gsub, and then I would combine all consecutive instances of \n using squeeze(arg):
str.gsub("\r", "\n").squeeze("\n")
which would result in :
#=>
"Useful Line 1 ....
Useful Line 2
Useful Line 3
Useful Line 4...
Useful Line 5
Useful Line 6
Useful Line 7
Useful Line 8
Useful Line 9
Useful Line 10
Useful Line 11
Useful Line 12"
...which brings me to our next issue. Sometimes those extra line breaks contain unwanted whitespace and not truly blank or empty lines. To deal with not only line breaks but also unwanted empty lines, I would add the each_line, reject, and strip method like so:
str.gsub("\r", "\n").squeeze("\n").each_line.reject{|x| x.strip == ""}.join
which would result in the desired string:
#=>
Useful Line 1 ....
Useful Line 2
Useful Line 3
Useful Line 4...
Useful Line 5
Useful Line 6
Useful Line 7
Useful Line 8
Usefule Line 9
Useful Line 10
Useful Line 11
Useful Line 12
Now more specifically to the OP, we could then simply use split("\n") to finish it all off (as was already mentioned by others):
str.gsub("\r", "\n").squeeze("\n").each_line.reject{|x| x.strip == ""}.join.split("\n")
or we could simply skip straight to the desired array by replacing each_line with map and leaving off the unnecessary join like so:
str.gsub("\r", "\n").squeeze("\n").split("\n").map.reject{|x| x.strip == ""}
both of which would result in:
#=>
["Useful Line 1 ....", " Useful Line 2", "Useful Line 3", " Useful Line 4... ", "Useful Line 5", " Useful Line 6", "Useful Line 7", " Useful Line 8 ", "Usefule Line 9", " Useful Line 10", "Useful Line 11 ", " Useful Line 12"]
NOTE:
You may also want to strip off leading and trailing whitespace from each line in which case we could replace .join.split("\n") with .map(&:strip) like so:
str.gsub("\r", "\n").squeeze("\n").each_line.reject{|x| x.strip == ""}.map(&:strip)
or
str.gsub("\r", "\n").squeeze("\n").split("\n").map.reject{|x| x.strip == ""}.map(&:strip)
which would both result in:
#=>
["Useful Line 1 ....", "Useful Line 2", "Useful Line 3", "Useful Line 4...", "Useful Line 5", "Useful Line 6", "Useful Line 7", "Useful Line 8", "Usefule Line 9", "Useful Line 10", "Useful Line 11", "Useful Line 12"]

Sublime Text - Goto line and column

Currently, the Go to line shortcut (CTRL+G in windows/linux) only allows to navigate to a specific line.
It would be nice to optionally allow the column number to be specified after comma, e.g.
:30,11 to go to line 30, column 11
Is there any plugin or custom script to achieve this?
Update 3
This is now part of Sublime Text 3 starting in build number 3080:
Goto Anything supports :line:col syntax in addition to :line
For example, you can use :30:11 to go to line 30, column 11.
Update 1 - outdated
I just realized you've tagged this as sublime-text-3 and I'm using 2. It may work for you, but I haven't tested in 3.
Update 2 - outdated
Added some sanity checks and some modifications to GotoRowCol.py
Created github repo sublimetext2-GotoRowCol
Forked and submitted a pull request to commit addition to package_control_channel
Edit 3: all requirements of the package_control repo have been met. this package is now available in the package repository in the application ( install -> GotoRowCol to install ).
I too would like this feature. There's probably a better way to distribute this but I haven't really invested a lot of time into it. I read through some plugin dev tutorial really quick, and used some other plugin code to patch this thing together.
Select the menu option Tools -> New Plugin
A new example template will open up. Paste this into the template:
import sublime, sublime_plugin
class PromptGotoRowColCommand(sublime_plugin.WindowCommand):
def run(self, automatic = True):
self.window.show_input_panel(
'Enter a row and a column',
'1 1',
self.gotoRowCol,
None,
None
)
pass
def gotoRowCol(self, text):
try:
(row, col) = map(str, text.split(" "))
if self.window.active_view():
self.window.active_view().run_command(
"goto_row_col",
{"row": row, "col": col}
)
except ValueError:
pass
class GotoRowColCommand(sublime_plugin.TextCommand):
def run(self, edit, row, col):
print("INFO: Input: " + str({"row": row, "col": col}))
# rows and columns are zero based, so subtract 1
# convert text to int
(row, col) = (int(row) - 1, int(col) - 1)
if row > -1 and col > -1:
# col may be greater than the row length
col = min(col, len(self.view.substr(self.view.full_line(self.view.text_point(row, 0))))-1)
print("INFO: Calculated: " + str({"row": row, "col": col})) # r1.01 (->)
self.view.sel().clear()
self.view.sel().add(sublime.Region(self.view.text_point(row, col)))
self.view.show(self.view.text_point(row, col))
else:
print("ERROR: row or col are less than zero") # r1.01 (->)
Save the file. When the "Save As" dialog opens, it should be in the the Sublime Text 2\Packages\User\ directory. Navigate up one level to and create the folder Sublime Text 2\Packages\GotoRowCol\ and save the file with the name GotoRowCol.py.
Create a new file in the same directory Sublime Text 2\Packages\GotoRowCol\GotoRowCol.sublime-commands and open GotoRowCol.sublime-commands in sublime text. Paste this into the file:
[
{
"caption": "GotoRowCol",
"command": "prompt_goto_row_col"
}
]
Save the file. This should register the GotoRowCol plugin in the sublime text system. To use it, hit ctrl + shift + p then type GotoRowCol and hit ENTER. A prompt will show up at the bottom of the sublime text window with two number prepopulated, the first one is the row you want to go to, the second one is the column. Enter the values you desire, then hit ENTER.
I know this is a complex operation, but it's what I have right now and is working for me.

Cucumber and variables internal to methods called indirectly

Please note: I am new to TDD & cucumber, so the answer may be very easy.
I am creating a basic image editor for a test (the image is just a sequence of letters).
I have written a Cucumber story:
Scenario Outline: edit commands
Given I start the editor
And a 3 x 3 image is created
When I type the command <command>
Then the image should look like <image>
The step
Scenarios: colour single pixel
| command | image |
| L 1 2 C | OOOCOOOOO |
always fails, returning
expected: "OOOCOOOOO"
got: " OOOOOOOO" (using ==) (RSpec::Expectations::ExpectationNotMetError)
This is the step code:
When /^I type the command (.*)$/ do |command|
#editor.exec_cmd(command).should be
end
The function exec_cmd in the program recognizes the command and launches the appropriate action. In this case it will launch the following
def colorize_pixel(x, y, color)
if !#image.nil?
x = x.to_i
y = y.to_i
pos = (y - 1) * #image[:columns] + x
#image[:content].insert(pos, color).slice!(pos - 1)
else
#messenger.puts "There's no image. Create one first!"
end
end
However, this always fails unless I hardcode the values of the two local variables (pos and color) in the function in the program itself.
Why? It doesn's seem I'm doing anything wrong in the program itself: the function does what it's supposed to do and those two variables are only useful locally. So I'd think this is a problem with my use of cucumber. How do I properly test this?
---edit---
def exec_cmd(cmd = nil)
if !cmd.nil?
case cmd.split.first
when "I" then create_image(cmd[1], cmd[2])
when "S" then show_image
when "C" then clear_table
when "L" then colorize_pixel(cmd[1], cmd[2], cmd[3])
else
#messenger.puts "Incorrect command. " + "Commands available: I C L V H F S X."
end
else
#messenger.puts "Please enter a command."
end
end
When /^I type the command (.*)$/ do |command|
#output = #editor.exec_cmd(command)
end
Then /^the image should look like (.)*$/ do |expected_image|
#output.should == expected_image
end
Hope this may help you.
It's not a cucumber issue.
The problem was that, in exec_cmd, split was called only in the "case" clause, not in the "when"s. This meant that, since the command's format was "a 1 2 b", cmd[1] in the "when" would call the second character of the string, a space, not the second value of the array, and the other functions would convert that to_i, returning 0.
I changed exec_cmd like this:
def exec_cmd(cmd = nil)
if !cmd.nil?
cmd = cmd.split
case cmd.first
when "I" then create_image(cmd[1], cmd[2])
[...]
end
which fixed the issue.
