Probably quite a niche question, but I believe in the power of a big community: Is it possible to set up jEdit in way, that it automatically inserts a comment character (//, #, ... depending on the edit mode) at the beginning of a new line, if the line before the wrap was a comment?
Sample:
# This is a comment spanning multiple lines. If I continue to type here, it
# wraps around automatically, but I have to manually add a `#` to each line.
If I continue to type after the . the third line should start with the # automatically. I searched in the plugin repository but could not find anything related.
Background: jEdit has the concepct of soft and hard wrap. While soft wrap only breaks lines visually at a character limit, it does not insert line breaks in the file. Hard wrap on the other hand inserts \n into the file at the desired character count.
This is not exactly what you want: I use the macros Enter_with_Prefix.bsh to automatically insert the prefix (e.g., #, //) at the beginning of the new line.
Description copied from Enter_with_Prefix.bsh:
Enter_with_Prefix.bsh - a Beanshell macro for jEdit
that starts a new line continuing any recognized
sequence that started the previous. For example,
if the previous line beings with "1." the next will
be prefixed with "2.". It supports alpha lists (a., b., etc...),
bullet lists (+, =, *, etc..), comments, Javadocs,
Java import statements, e-mail replies (>, |, :),
and is easy to extend with new sequence types. Suggested
shortcut for this macro is S+ENTER (SHIFT+ENTER).

Hello I want to know any trick or shortcut by which one can know which is the longest file in project.
i.e which file has the longest lines of code.Is there any shortcut or plugin available?
I believe the OP was asking about the length of file, not the length of single line. You can try with such iteration:
(.*\n){100,}
(.*\n){1000,}
(.*\n){10000,}
Although this is kind of hacky it still works.
You can search your whole project using the regex repetition pattern. Just right-click your project folder in the project structure view and choose "Find in path...". Be sure to check "Regex" in the search window that appears.
So you'll start out and match any line with any length in your project
^.$
(If you're not familiar with regex: ^ and $ are used to denote the beginning and end of a line and . matches any character)
Then you gradually increase the number of matched repetitions
^.{1,}$
^.{10,}$
^.{100,}$
^.{1000,}$
(You use {start, end} to indicate to interval of repetitions. If you leave end blank it will match anything from start)
Using this you will soon be left with the longest line(s) in your project.
As I said it's kinda hacky but it's also quick and works if you don't have to automate the task.
Hope this helps you!
All.
I am used to programming VBA in Excel, but am new to the structures in Word.
I am working through a library of text files to update them. Many of them are either OCR documents, or were manually entered.
Each has a recurring pattern, the most common of which is unnecessary carriage returns.
For example, I am looking at several text files where there is a double return after each line. A search and replace of all double carriage returns removes all paragraph distinctions.
However, each line is approximately 30 characters long, and if I manually perform the following logic, it gives me a functional document.
If there is a double carriage return after 30+ characters, I replace them with a space.
If there were less than 30 characters prior to the double return, I replace them with a single return.
Can anyone help me with some rudimentary code that would help me get started on that? I could then modify it for each "pattern" of text documents I have.
e.g.
In this case, there are more than
thirty characters per line. And I
will keep going to illustrate this
example.
This would be a new paragraph, and
would be separated by another of
the single returns.
I want code that would return:
In this case, there are more than thirty character returns. And I will keep going to illustrate this example.
This would be a new paragraph, and would be separated by another of the single returns.
Let me know if anyone can throw something out that I can play with!
You can do this without code (which RegEx requires), simply using Word's own wildcard Find/Replace tools, where:
Find = ([!^13]{30,})[^13]{1,}
Replace = \1^32
and, to clean up the residual multi-paragraph breaks:
Find = [^13]{2,}
Replace = ^p
You could, of course, record the above as a macro...
Here is a RegEx that might work for you:
(\n\n)(?<!\.(\n\n))
The substitution is just a plain space, you can try it out (and modify / tweak it) here: https://regex101.com/r/zG9GPw/4
This 'pattern' tells the RegEx engine to look for the newline character \n which occurs x2 like this \n\n (worth noting this is from your question and might be different in your files, e.g. could be \r\n) and it assumes that a valid line break will be proceeded by a full stop: \..
In RegEx the full stop symbol is a single character wild card so it needs to be escaped with the '\' (n and r are normal characters, escaping them tells the RegEx engine they represent newline and return characters).
So... the expression is looking for a group of x2 newline characters but then uses a negative look-behind to exclude any matches where the previous character was a full stop.
Anyway, it's all explained on the site:
Here is how you could do a RegEx find and replace using NotePad++ (I'm not sure if it comes with RegEx or if a plugin is needed, either way it is easy). But you can set a location, filters (to target specific file types), and other options (such as search in sub-directories).
Other than that, as #MacroPod pointed out you could also do this with MS Word, document by document, not using any code :)
I have an SQL export file from my server with comments. The line comment operator used was the hashtag #. Notepad++ does not treat this like a commented out line, as in, the color does not change and any words such as like and while are changed to bold blue.
When you run the script on the server to install the SQL, it runs fine, the comments are treated as they should be. How do you tell NPP that the # operator is supposed to comment out the line? Both show the color and have Ctrl-k add a # in front of the line.
Note: I added commentLine="#" in the langs.xml file with no luck.
View -> User defined Dialogue -> Comment & number -> Comment Line
There you type in "#"
Before this you need to define a new language in the upper buttons.
What means, that the whole rest of the syntax isn't highlighted anymore.
But you could define it that way, how you want to. So you have an individual Syntax Highlighting including the commenting via "#"
I am working with another human being on project from that the professor expects to have uniform code-style. We have written large separate junks of code on our own, in which one has written single line comments without a white-space between the single-line-comment-token and the other one has inserted a white-space. We are working with IntelliJ and have failed to find an option to enable the Reformat Code function, to insert a white-space.
TLDR:
Can you tell us how to convert comments from that to this in IntelliJ?
// This is a load bearing comment - don't dare to remove it
//This is a load bearing comment - don't dare to remove it!
You can do a global search and replace (ctrl-shift-r on windows with default keyboard layout, or Replace in Path under the Edit/Find menu).
Check the regular expression option and enter //(\S.*) as the text to find and // $1 as the replacement. Check the whole project option, and clear any file masks. You can single step through the replacements, or simply hit the All Files option.
According to TkDocs:
The "1.0" here represents where to insert the text, and can be read as "line 1, character 0". This refers to the first character of the first line; for historical conventions related to how programmers normally refer to lines and characters, line numbers are 1-based, and character numbers are 0-based.
I hadn't heard of this convention before, and I can't find anything relevant on Google. Can anyone explain this to me please?
I think you're referring to Tk's text widget. The man page says:
Lines are numbered from 1 for consistency with other UNIX programs that use this numbering scheme.
Although, I'm not sure which Unix tools it's talking about.
Update:
As mentioned in the comments, it looks like a lot of unix text manipulation tool starts line numbering at 1. And tcl/tk having a unix origin, it makes sense to be as compatible as possible with the underlying OS environment.
It really is nothing more than convention, but here is a suggestion.
Character positions are generally thought of in the same way as a Java iterator, which is a "pointer" to a position between two characters. Thus the first character is the one after index position 0. Substrings are taken between two inter-character positions, for instance.
Line positions on the other hand are generally thought of more in the way of a .NET enumerator, which is a "pointer" to the item itself, not to a position in between. Thus the first line is the line at position 1.
