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 urllibfrom bs4 import BeautifulSoupfrom w3lib.url import safe_url_string# ASCII link for solved encoding problems —
# https://stackoverflow.com/a/40654295/5951529
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://stackoverflow.com/a/11923803/5951529
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://stackoverflow.com/a/3942100/5951529
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# https://stackoverflow.com/a/32451970/5951529
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 urllibfrom bs4 import BeautifulSoupfrom w3lib.url import safe_url_stringimport sublime_pluginclass KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):def run(self, edit):# Get selection textprint('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://stackoverflow.com/a/40654295/5951529ascii_link = safe_url_string(u'http://duckduckgo.com/html/?q=' + (selection_text),encoding="UTF-8")print(ascii_link)# SERP DuckDuckGoserp = urllib.request.urlopen(ascii_link)# Reading SERPread_serp = serp.read()# BeautifulSoup — https://stackoverflow.com/a/11923803/5951529parsed = BeautifulSoup(read_serp, "lxml")# Parsed first linkfirst_link = parsed.findAll('div', {'class': re.compile('links_main*')})[0].a['href']# Remove DuckDuckGo specific characters —# https://stackoverflow.com/a/3942100/5951529remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")# Final link — https://stackoverflow.com/a/32451970/5951529final_link = (urllib.parse.unquote(remove_duckduckgo_symbols))markdown_link = '[' + selection_text + ']' + \'(' + final_link + ')'print(markdown_link)# Replace selected text to Markdown linkself.view.replace(edit, selection_region, markdown_link)
4. Expected behavior
If user have installed Python and install packages
pip install beautifulsoup4
pip install lxml
pip 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_pluginm = importlib.import_module(modulename)File "./python3.3/importlib/__init__.py", line 90, in import_moduleFile "<frozen importlib._bootstrap>", line 1584, in _gcd_importFile "<frozen importlib._bootstrap>", line 1565, in _find_and_loadFile "<frozen importlib._bootstrap>", line 1532, in _find_and_load_unlockedFile "<frozen importlib._bootstrap>", line 584, in _check_name_wrapperFile "<frozen importlib._bootstrap>", line 1022, in load_moduleFile "<frozen importlib._bootstrap>", line 1003, in load_moduleFile "<frozen importlib._bootstrap>", line 560, in module_for_loader_wrapperFile "<frozen importlib._bootstrap>", line 868, in _load_moduleFile "<frozen importlib._bootstrap>", line 313, in _call_with_frames_removedFile "D:\Sublime Text Build 3126 x64 For Debug\Data\Packages\Grace Splitter\kristi.py", line 4, in <module>from bs4 import BeautifulSoup

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
- sublime-beautifulsoup4,
- sublime-lxml,
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 runparsed = 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 BeautifulSoupclass KristinitaLuckyLinkCommand(sublime_plugin.TextCommand):def run(self, edit):# Get selection textprint('KristinitaLuckyLink called')select = self.view.sel()selection_region = select[0]selection_text = self.view.substr(selection_region)print(selection_text)# Get terminal output — https://stackoverflow.com/a/4760517/5951529# Paths is correctresult = 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 linkmarkdown_link = '[' + selection_text + ']' + \'(' + final_link + ')'print(markdown_link)# Replace selected text to Markdown linkself.view.replace(edit, selection_region, markdown_link)
My KrisDuckDuckGo.py
file:
import urllibimport sys
sys.path.append('D:\Sublime Text 3 x64\Data\Packages\KristinitaLuckyLink\KristinitaLuckyLink.py')from w3lib.url import safe_url_stringfrom KristinitaLuckyLink import selection_textfrom bs4 import BeautifulSoup# ASCII link for solved encoding problems —
# https://stackoverflow.com/a/40654295/5951529
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://stackoverflow.com/a/11923803/5951529
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://stackoverflow.com/a/3942100/5951529
remove_duckduckgo_symbols = first_link.replace("/l/?kh=-1&uddg=", "")
# Final link — https://stackoverflow.com/a/32451970/5951529
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.
