Re: Accessing clipboard through software built on Python
You don't have to start from scratch. You don't to do anything other than learn to use anamnesis. I use anamnesis as my clipboard manager. I you can easily tell to get which ever one you want (i.e. the thousandth item). # Inform yourself https://sourceforge.net/projects/anamnesis/ # Install it cd ~/bin/src/ wget -O anamnesis.tar.gz https://sourceforge.net/projects/anamnesis/files/latest/download tar xzf anamnesis.tar.gz ln -sf ~/bin/src/anamnesis-1.0.4/source/anamnesis.py ~/bin/anamnesis # Be happy It hasn't changed in years and that's just fine. I just works. I can access it through the command line when I am in a remote ssh session. Or I have it as a autostarted daemon. It uses sqlite to store all your copied (and selected, if configured) text, which can be slow on a spinning disk. If this turns you off, replace your OS hard drive with an ssd - life's too short.

regular expression problem
Dear list members,
I cannot figure out why my regular expression does not work as I expect it to:
#---
#!/usr/bin/python
from __future__ import print_function
import re as regex
rx_works = '\$<[^<:]+?::.*?::\d*?>\$|\$<[^<:]+?::.*?::\d+-\d+>\$'
# it fails if switched around:
rx_fails = '\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$'
line = 'junk $$ junk $$
junk'
print ('')
print ('line:', line)
print ('expected: $$')
print ('expected: $$')
print ('')
placeholders_in_line = regex.findall(rx_works, line, regex.IGNORECASE)
print('found (works):')
for ph in placeholders_in_line:
print (ph)
print ('')
placeholders_in_line = regex.findall(rx_fails, line, regex.IGNORECASE)
print('found (fails):')
for ph in placeholders_in_line:
print (ph)
#---
I am sure I simply don't see the problem ?
Thanks,
Karsten

To get the highlighted text in X without needing a copy, you want the PRIMARY X selection rather than CLIPBOARD. I think pyperclip can get it (it uses an external program like xsel, and xsel can get any of the three X selections), or you can get the selection using a GUI library like GTK, Qt or Tk.

Here are some of the steps while matching the second regex. (View this
in a monospaced font.)
1:
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
2:
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
3:
The .*? matches as few characters as possible, initially none.
junk $$ junk $$ junk
^
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
4:
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
At this point it can't match, so it backtracks.
5:
The .*? matches more characters, including the ":".
After more matching it's like the following.
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
6:
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
Again it can't match, so it backtracks.
7:
The .*? matches more characters, including the ":".
After more matching it's like the following.
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
8:
junk $$ junk $$ junk
^
\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$
^
Success!
The first choice has matched this:
$$ junk $$

Re: regular expression problem
Now that MRAB has shown me the follies of my ways I would like to learn how to properly write the regular expression I need. This part: > rx_works = '\$<[^<:]+?::.*?::\d*?>\$|\$<[^<:]+?::.*?::\d+-\d+>\$' > # it fails if switched around: > rx_fails = '\$<[^<:]+?::.*?::\d+-\d+>\$|\$<[^<:]+?::.*?::\d*?>\$' suggests that I already have a solution. However, in reality this line: > line = 'junk $$ junk $$ > junk' can be either way round (match_A, then match_B or the vice versa) which, in turn, will switch the rx_works/rx_fails. Let my try to explain the expression I am actually after (assuming .compile with re.VERBOSE): rx_works = ' \$< # start of match is literal '$<' anywhere inside string [^<:]+?:: # followed by at least one "character", except '<' or ':', until the next '::' (this is the placeholder "name") .*?:: # followed by any number of any "character", until the next '::'(this is the placeholder "options") \d*?# followed by any number of digits (the max length of placeholder output) >\$ # followed by '>$' | # -- OR (in *either* order) -- \$< # start of match is literal '$<' anywhere inside string [^<:]+?:: # followed by at least one "character", except '<' or ':', until the next '::' (this is the placeholder "name") .*?:: # followed by any number of any "character", until the next '::'(this is the placeholder "options") # now the difference: \d+-\d+ # followed by one-or-many digits, a '-', and one-or-many digits (this is the *range* from with placeholder output) >\$'# followed by '>$' I want this to work for any number of matches in any order of max-lenght or output-range inside one string. Now, why the [^<:]+? dance ? Because three levels of placeholders $<...::...::>$ $<<...::...::>>$ $<<<...::...::>>>$ need to be nestable inside each other ;-) Anyone able to help ? This seems beyond my current grasp of regular expressions. Thanks, Karsten -- GPG 40BE 5B0E C98E 1713 AFA6 5BC0 3BEA AC80 7D4F C89B -- https://mail.python.org/mailman/listinfo/python-list

I mean:

You can then interpret what you have extracted afterwards.
Maybe if you want to have the single ones grouped you could consider:
>>> t = t*2
>>> t
''

zenity substitution
Hi all, I'm new to Python, but not to programming. As a teaching exercise, I am converting a bunch of bash shell scripts to Python, so that they can be run on all three OS-es (Linux, Windows, MacOS). The scripts in questions make extensive use of Linux "zenity" dialogs. Is there an equivalent facility in Python 3? If so, what is it? TIA -- https://mail.python.org/mailman/listinfo/python-list

You'll almost certainly have easier access to selected text (not in Python, though). Really though you might want to take a step back and take the web page out the the equation completely. Salesforce must have an API, right? And the email addresses you're copying are presented in some regular format you might be able to parse (using beautifulsoup or something)? Or maybe the data source has an API, even? Or a database you can access? Surely, you could write a program that somehow gets (all) the data you want to copy from whatever server you get them from, gives you an opportunity to do whatever checks you have to do by hand, and then feeds the data into the database they go in in the end – or gives the data to you in a format that makes that last step easy. Right? All I'm saying is: if you're going to try to automate a job, you might as well do it with conviction ^_^ If you insist on getting the selected text with something like autohotkey, my hunch is that the simplest way to do this would be to inject Ctrl+C, wait a moment, and then retrieve the clipboard content. -- https://mail.python.org/mailman/listinfo/python-list
