I’m finding that I’m reusing the same replace modifier in multiple places around my Smarty template files to replace some non-alphanumeric characters.
An example:
{markdown text=$star.description|replace:'’':'’'|replace:'‘':'‘'|replace:'“':'“'|replace:'”':'”'|replace:' – ':' — '|replace:' — ':' — '|replace:'…':'…'|replace:'é':'é'}
Ideally, I should keep that list of replace phrases in one place and reference that whenever I need to, but I can’t find the right way to do that in Smarty.
You can create a modifier in smarty so then you can call it this way (if i.e. you named it "cleantext"):
{markdown text=$star.description|cleantext}

I am trying to find a way to remove all from a tag pair in VS Code.
I’ve been using Notepad++ for this purpose, but for some unknown reason it doesn't work all the time. So, I hope if there is such a possibility in VS Code, it’d be more reliable.
Here is the instruction for Notepad++:
Search for -
<wp:post_name>[^<>]+</wp:post_name>
and replace all with -
<wp:post_name></wp:post_name>
Is there anything like this in VS Code?
I’d really appreciate it if someone can help.
Before using what is suggested in this solution, backup your files, and run the search and replace on a small sample. Be sure to check the outcome to all the possible combinations you can have in your files.
You can achieve what you need with Notepad++ (and SublimeText 3, with RegEx search and replace), and this answer will cover that. Since I've never used Visual Studio Code, I can't say if it will work in it as well.
Consider the following regular expression.
<foo>(.*?)<\/foo>
If we were to apply it to the following text:
<foo><some special chars>!##$%^&*</foo> sure, why not
<foo>Lorem</foo>
<foo>ipsum</foo>
<foo>sit</foo>
<foo>dolor</foo>
<foo>amet</foo>
<bar>elm stuff</bar>
more stuff for you <foo> something </foo> and even more stuff <foo>yes</foo>
it would match all the parts of the text which begin with <foo> and end with </foo>, regardless of what's between them.
If you want to play around with this, I've created an example here.
As far as using this in Notepad++, open the search window, navigate to the Find in files tab, and set it up like in the following image.
You would, of course, need to change the search and replacement strings to those you plan on using, optionally set up a file extension for which to do the replacement (Filters), and set the directory in which to perform find-and-replace.
Limitations
1. Nesting
In case your text contains nested tags of the same kind, like this:
Let's deal with nesting: <foo> some text <foo> a child foo!</foo> let's close the parent</foo>
doing the suggested RegEx search and replace, will turn the previous line of text into this:
Let's deal with nesting: <foo></foo> let's close the parent</foo>
If you don't have nested tags of the same kind, you should be in the clear. Unless...
2. Newlines
The provided RegEx will not match cases where your opening tag shows up in one line, and the closing tag shows up in another line. To match those, you would need to change the original RegEx:
<foo>(.*?)<\/foo>
to this:
<foo>([\s\S]*?)<\/foo>
\s will match any whitespace character (including newlines), while \S will match any non-whitespace character.
I'm trying to replace a few character word in one place with the word searched in another. I.e
VARIABLE INT005 SOME TEXT BETWEEN NAME=INT020;
I want the program To copy whats after VARIABLE (INT005 in this case) and paste it after NAME=(here should be again INT005 replaced into the place of INT020)
A regex replacement should work here. Assuming you are only looking to make these replacements on a single line, you may try the following find and replace:
Find: \bVARIABLE (\S+)(.*?)\bNAME=\S+;
Replace: VARIABLE $1$2NAME=$1
Demo
Edit:
If your text could span multiple lines, then either turn on "dot all" mode from Textpad (not sure where you would do that), or use this find version:
\bVARIABLE (\S+)([\s\S]*?)\bNAME=\S+;
Let's say we want to replace "apple" to "banana" in every file in the current project. We can do this with Cmd+Shift+F (Find in Files...) and "Replace" button. But this button replaces all simultaneously. What I want to do is replacing one by one. I know this can be done in a single file with Alt+Cmd+F and "Replace" button.
Is there any ways to do in SublimeText3?
Thank you
You can't replace across multiple files in the same way as you can replace in a single file.
The closest you can get is to use Find in Files, make sure Use Buffer is toggled on, and then use Find to perform the search, a Find Results buffer will open. Now you can use F4 to jump straight to the next results line (Shift+F4 to the previous), but you need to manually move the cursor to the relevant section(s) of the line and make the alterations manually.
When performing replacements across files, if it's not a simple case of replacing all of some text with some other text, I have found it best to use a regex to make sure that only the matches I want changed will get changed. Occasionally, if creating a complex regex, I will end up testing the regex using Find to be certain of what it matches, before then running the same regex with replace.
The exact problem: I have a source in C++ and I need to replace a symbol name to some other name. However, I need that this replace the symbol only, not accidentally the same looking word in comments or text in "".
The source information what particular language section it is, is enough defined in the syntax highlighting rules. I know they can fail sometimes, but let's state this isn't a problem. I need some way to walk through all found occurrences of the phrase, then check in which section it is found, and if it's text or comment, this phrase should be skipped. Otherwise the replacement should be done either immediately, or by asking first, depending on well known c flag.
What I imagine would be at least theoretically possible is:
Having a kinda "callback" when doing substitution (called for each phrase found, and requesting the answer whether to substitute or not), or extract the list of positions where the phrase has been found, then iterate through all of them
Extract the name of the current "hi-linked" syntax highlighting rule, which is used to color the text at given position
Is it at all possible within the current features of vim?
Yes, with a :help sub-replace-expression, you can evaluate arbitrary expressions in the replacement part of :substitute. Vim's synID() and synstack() functions allow you to get the current syntax element.
Luc Hermitte has an implementation that omits replacement inside strings, here. You can easily adapt this to your use case.
With the help of my ingo-library plugin, you can define a short predicate function, e.g. matching comments and constants (strings, numbers, etc.):
function! CommentOrConstant()
return ingo#syntaxitem#IsOnSyntax(getpos('.'), '^\%(Comment\|Constant\)$')
endfunction
My PatternsOnText plugin now provides a :SubstituteIf command that works like :substitute, but also takes a predicate expression. With that, it's very easy to do a replacement anywhere except in comments or constants:
:%SubstituteIf/pattern/replacement/g !CommentOrConstant()
I have the following source code from the Wikipedia page of a list of Games. I need to grab the name of the game from the source, which is located within the title attribute, as follows:
<td><i>007: Quantum of Solace</i><sup id="cite_ref-4" class="reference"><span>[</span>4<span>]</span></sup></td>
As you can see above, in the title attribute there's a string. I need to use GREP to search through every single line for when that occurs, and remove everything excluding:
title="Game name"
I have the following (in TextWrangler) which returns every single occurrence:
title="(.*)"
How can I now set it to remove everything surrounding that, but to ensure it keeps either the string alone, or title="string".
I use a multi-step method to process these kind of files.
First you want to have only one HTML tag per line, GREP works on each line so you want to minimise the need for complicated patterns. I usually replace all: > with >\n
Then you want to develop a pattern for each occurrence of the item you want. In this case 'title=".?"'. Put that in between parentheses (). Then you want add some filling to that statement to find and replace all occurrences of this pattern: .?(title=".?").
Replace everything that matches .?(title=".?").* with \1
Finally, make smart use of the Textwrangler function process lines containing, to filter any remaining rubbish.
Notes
the \1 refers to the first occurrence of a match between () you can also reorder stuff using multiple parentheses and use something like (.?), (.) with \2, \1 to shuffle columns.
Learn how to do lazy regular expressions. The use of ? in these patterns is very powerfull. Basically ? will have the pattern looking for the next occurrence of the next part of the pattern not the latest part that the next part of your pattern occurs.
I've figured this problem out, it was quite simple. Instead of retrieving the content in the title attribute, I'd retrieve the page name.
To ensure I only struck the correct line where the content was, I'd use the following string for searching the code.
(.)/wiki/(.)"
Returning \2
After that, I simply remove any cases where there is HTML code:
<(.*)
Returning ''
Finally, I'll remove the remaining content after the page name:
"(.*)
Returning ''
A bit of cleaning up the spacing and I have a list for all game names.
