[SOLVED] Problem with settings.get() inside from regex

#1

Hi guys,

i have a problem with regex and using the settings.get() function together.

My User Settings looks like:

{
	"ignored_packages":
	
		"DocBlockr",
		"Vintage"
	],
	"Username"	: "my username",
	"Company"	: "company name"

}

I created a new plugin with the following code:

import sublime, sublime_plugin
import re

# Provide completions that match just after typing an opening angle bracket
class myReplaceCompletions(sublime_plugin.EventListener):
    
    def on_query_completions(self, view, prefix, locations):
        # Only trigger within js
        if not view.match_selector(locations[0],
                "source.js"):
            return ]

        ### initialize config
        myConfig        = sublime.load_settings("Preferences.sublime-settings")
        
        ### test to return an value from the settings
        config          = myConfig.get("Username")

        ### some to return an value from the setting
        ### which uses an external variable to get the key
        config_value    = "Username"
        config2         = myConfig.get(config_value)

        ### string to replace
        string          = "/** * * @author: {{Setting:Username}} * @company: {{Setting:Company}} ***/"
        
        ### pattern
        regex           = "{{Setting:(.*?)}}"

        #test with get() as string
        myReplace       = re.sub(regex, "myConfig.get("r'\1'")", string)
        
        ### test with get() as function - use config_value (static)
        myReplace2      = re.sub(regex, myConfig.get(config_value), string)

        ### test with get as function - use regex repsonse
        ### not working
        #myReplace3      = re.sub(regex, myConfig.get(r'\1'), string)

        return (
            ("myReplace", myReplace),
            ("myReplace2", myReplace2),
            #("myReplace3", myReplace3),
            ("myConfigValue", "this is config 1: "+config),
            ("myConfigValue2", "this is config 2: "+config2)
        ], sublime.INHIBIT_WORD_COMPLETIONS | sublime.INHIBIT_EXPLICIT_COMPLETIONS)

This code is copied and modified from the HTML Tab Completions.

Why I want this?

I started with snippets(1) and tmPreferences files. But there are some problems with the file permissions in Sublime Text 3.
So i began to use sublime-completions, which are good for small code snippets.

Now i want to use the code from my old snippets(1) and replace the variables, which are defined as $MY_COMPANY in the snippet file.

My idea was to use the placeholders like {Setting:Username} in my new code snippets and replace it dynamicly at execution.

Example:

{Setting:Username} will be replaced with myConfig.get(“Username”). Username is in this case \1 from my regex.

I hope you know what i mean.

Thanks for any response and feedback.

//EDIT
Sorry, forgot to paste the first part :blush:

Marcus

Why don’t you retrieve the value, then use that as your key in 2 steps. How you are doing it won’t work. re.sub takes 3 arguments, a regex, a replacement, and a string to run on. You have the first and last points down, but I think you are confused for the second. For myReplace3, you are effectively getting a string from myConfig with a key of r’\1’. This is likely returning None, which isn’t what you want. If there is a match, you can access the groups by doing something like the following.

match = re.search(regex, string)
if match:
    key = match.group(1)
    myReplace3 = re.sub(regex, myConfig.get(key), string)

Hi,

yeah this works :smile:

But i have now the problem, that each placeholder will be replaced with the values from the first match.

Any idea? I checked the regex (via an online regex tool) and this shows me both placeholder entries.

Output:


//myReplace
/**
 *
 * @author: my username
 * @company: my username
 *
**/

//myKey
Username

Plugin:

import sublime, sublime_plugin
import re

# Provide completions that match just after typing an opening angle bracket
class myReplaceCompletions(sublime_plugin.EventListener):
    
    def on_query_completions(self, view, prefix, locations):
        # Only trigger within js
        if not view.match_selector(locations[0],
                "source.js"):
            return ]

        ### initialize config
        myConfig        = sublime.load_settings("Preferences.sublime-settings")

        ### string to replace
        string          = "/**\n *\n * @author: {{Setting:Username}}\n * @company: {{Setting:Company}}\n *\n**/"
        
        ### pattern
        regex           = "{{Setting:(.*?)}}"
        
        match = re.search(regex, string)
        if match:
            key = match.group(1)
            myReplace = re.sub(regex, myConfig.get(key), string) 

        return (
            ("myReplace", myReplace),
            ("myKey", key),
        ], sublime.INHIBIT_WORD_COMPLETIONS | sublime.INHIBIT_EXPLICIT_COMPLETIONS)

Instead of match = re.search(regex, string) use for match in re.finditer(regex, string):. Of course, adjust your indents as you need to.

Err actually, this isn’t what you want. I’ll update it later when I have some time. You might be able to keep iterating over your snippet after each replace, continuing till match returns None.

Try replacing the content after your regex definition and before the return statement with this.

for match in re.finditer(regex, string): key = match.group(1) string = re.sub(regex, myConfig.get(key), string, 1) myReplace = string

Hi,

sorry for the delay.

It works perfect.

Thanks a lot!
