1. Summary
I don't find, how Sublime Text plugins developer can use Sublime Text find global Python packages, not Python packages of Sublime Text directory.
Sublime Text use own Python environment, not Python environment of machine. Developers needs sys.path for set not built-in Sublime Text Python packages.
Is any methods, that use global installed Python packages in Sublime Text plugins? For example, it would be nice, if someone tells me, how I can change my plugin — see 3.2 item of this question.
2. Disadvantages of using Sublime Text 3 environment
- Sublime Text 3 Build 3126 use Python 3.3, but at the time of writing this question release Python 3.6 stable. Python 3.6 have more features.
- Developers needs add and update third-party Python packages, even they installed for users. It spends a time of developers.
- For developers there may be problems with dependencies of packages, see 6.2 item of this question.
3. Example
1. Python code
For example, I wrote Python code — replace Поиск Кристиниты to [**Поиск Кристиниты**](https://github.com/Kristinita/Kristinita.github.io), where https://github.com/Kristinita/Kristinita.github.io — first link of DuckDuckGo query Поиск Кристиниты.
# -*- coding: utf-8 -*-
import re
import urllib
from bs4 import BeautifulSoup
from w3lib.url import safe_url_string
# ASCII link for solved encoding problems —
# https://mcmap.net/q/1772772/-how-to-fetch-a-non-ascii-url-with-urlopen
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + 'Поиск Кристиниты',
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://mcmap.net/q/617945/-duckduckgo-api-not-returning-results
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://mcmap.net/q/63442/-remove-specific-characters-from-a-string-in-python
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# https://mcmap.net/q/86246/-url-decode-utf-8-in-python
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
# Markdown link
markdown_link = '[' + 'Поиск Кристиниты' + ']' + \
'(' + final_link + ')'
print(markdown_link)
If I run this file in terminal or SublimeREPL, I get in output:
[**Поиск Кристиниты**](https://github.com/Kristinita/Kristinita.github.io/)
2. Sublime Text plugin
Now, based on this code, I wrote Sublime Text plugin for replace example text to [**example text**](http://<first link for DuckDuckGo query “example link”>):
import re
import urllib
from bs4 import BeautifulSoup
from w3lib.url import safe_url_string
import sublime_plugin
class KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):
def run(self, edit):
# Get selection text
print('KristinitaLuckyLink called')
select = self.view.sel()
selection_region = select[0]
selection_text = self.view.substr(selection_region)
print(selection_text)
# ASCII link for solved encoding problems —
# https://mcmap.net/q/1772772/-how-to-fetch-a-non-ascii-url-with-urlopen
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + (selection_text),
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://mcmap.net/q/617945/-duckduckgo-api-not-returning-results
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://mcmap.net/q/63442/-remove-specific-characters-from-a-string-in-python
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# Final link — https://mcmap.net/q/86246/-url-decode-utf-8-in-python
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
markdown_link = '[' + selection_text + ']' + \
'(' + final_link + ')'
print(markdown_link)
# Replace selected text to Markdown link
self.view.replace(
edit, selection_region, markdown_link)
4. Expected behavior
If user have installed Python and install packages
pip install beautifulsoup4pip install lxmlpip install w3lib
I want, that my plugin from 2.2 item successful work for user.
5. Actual behavior
If I save my plugin, I get stack trace:
Traceback (most recent call last):
File "D:\Sublime Text Build 3126 x64 For Debug\sublime_plugin.py", line 109, in reload_plugin
m = importlib.import_module(modulename)

6. Not helped
1. Using global Python environment of computer
I don't find, how I can do it. Examples of questions, that I can find:
- How to include third party Python packages in Sublime Text 2 plugins,
- Using paramiko library in ST2 plugins,
- Best practices for plugin-deployment and packaging,
- How to import a package and call its global functions / to get their global variable values?
2. Using Sublime Text environment
I install
I copy my w3lib directory from C:\Python36\Lib\site-packages to Data\Packages directory of Sublime Text.
I run in Sublime Text 3 console:
>>> window.run_command("kristinita_lucky_link")
I get stack trace:
Traceback (most recent call last):
File "D:\Sublime Text 3 x64\sublime_plugin.py", line 818, in run_
return self.run(edit)
File "D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KristinitaLuckyLink.py", line 32, in run
parsed = BeautifulSoup(read_serp, "lxml")
File "D:\Sublime Text 3 x64\Data\Packages\bs4\__init__.py", line 165, in __init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?
I don't find, how I can set lxml.
3. Using variables in 2 files
For example I have KristinitaLuckyLink.py and KrisDuckDuckGo.py files in the same directory.
My KristinitaLuckyLink.py file:
import re
import requests
import sublime_plugin
import subprocess
import sys
sys.path.append(
'D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KrisDuckDuckGo.py')
from KrisDuckDuckGo import final_link
from bs4 import BeautifulSoup
class KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):
def run(self, edit):
# Get selection text
print('KristinitaLuckyLink called')
select = self.view.sel()
selection_region = select[0]
selection_text = self.view.substr(selection_region)
print(selection_text)
# Get terminal output — https://mcmap.net/q/25570/-running-shell-command-and-capturing-the-output
# Paths is correct
result = subprocess.run(["C:\Python36\python.exe", "D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\krisduckduckgo.py"],
stdout=subprocess.PIPE)
final_link = result.stdout.decode('utf-8')
print(final_link)
# Markdown link
markdown_link = '[' + selection_text + ']' + \
'(' + final_link + ')'
print(markdown_link)
# Replace selected text to Markdown link
self.view.replace(
edit, selection_region, markdown_link)
My KrisDuckDuckGo.py file:
import urllib
import sys
sys.path.append(
'D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KristinitaLuckyLink.py')
from w3lib.url import safe_url_string
from KristinitaLuckyLink import selection_text
from bs4 import BeautifulSoup
# ASCII link for solved encoding problems —
# https://mcmap.net/q/1772772/-how-to-fetch-a-non-ascii-url-with-urlopen
ascii_link = safe_url_string(
u'http://duckduckgo.com/html/?q=' + (selection_text),
encoding="UTF-8")
print(ascii_link)
# SERP DuckDuckGo
serp = urllib.request.urlopen(ascii_link)
# Reading SERP
read_serp = serp.read()
# BeautifulSoup — https://mcmap.net/q/617945/-duckduckgo-api-not-returning-results
parsed = BeautifulSoup(read_serp, "lxml")
# Parsed first link
first_link = parsed.findAll(
'div', {'class': re.compile('links_main*')})[0].a['href']
# Remove DuckDuckGo specific characters —
# https://mcmap.net/q/63442/-remove-specific-characters-from-a-string-in-python
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# Final link — https://mcmap.net/q/86246/-url-decode-utf-8-in-python
final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))
print(final_link)
I select any text → I print in Sublime Text console:
window.run_command("kristinita_lucky_link")
I don't get output in Sublime Text console.
7. Environment
Operating system and version:
Windows 10 Enterprise LTSB 64-bit EN
Sublime Text:
Build 3126
Python:
3.6.0
site_pathlike your example, but I get the same error like 6.2 section —bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?Thanks. – Ferromanganese
