to_clipboard(excel=False) truncates strings to 50 characters

[klonuo]

I hope this is not intended as I can't find the point in this behavior:

import pandas as pd
df = pd.DataFrame.from_dict({1: ''.join(['1234567890'] * 6)}, 'index')
df.to_clipboard(excel=False)

result copied to clipboard:

                                                   0
1  1234567890123456789012345678901234567890123456...

Another issue - trying to omit index:

df.to_clipboard(excel=False, index=False)

result copied to clipboard, just the same as previous (with index):

                                                   0
1  1234567890123456789012345678901234567890123456...

This doesn't happen if I leave excel parameter to default value.

So I think this needs to have some options set inside to_clipboard. As the default display options are used (but since this is converting to text, I think you want to eliminate max values)

so maybe also need to set max_rows,max_cols and such.

This is a work-around, but will call this a bug too.

In [3]: df = pd.DataFrame.from_dict({1: ''.join(['1234567890'] * 6)}, 'index')

In [4]: with pd.option_context('display.max_colwidth',9999999):
   ...:         df.to_clipboard(excel=False)
   ...:     

                                                          0

@klonuo if you'd like to do a pull-request would be great. tests are in pandas/io/tests/test_clipboard.py

should prob get a few test cases that fail on round-tripping (e.g. to_clipboard/from_clipboard) and test/fix for them

[klonuo]

@jreback clipboard tests report fine, so I run whole test suite on current github version with there results:

1. test_parsers.py crashes python at test_dialect (test_parsers.TestCParserHighMemory)
2. Tests that that report error:

test_encode (pandas.io.tests.test_html.TestReadHtmlEncodingLxml)
test_boxplot (pandas.tests.test_graphics.TestDataFramePlots)
test_boxplot_empty_column (pandas.tests.test_graphics.TestDataFramePlots)
test_boxplot_vertical (pandas.tests.test_graphics.TestDataFramePlots)
test_to_excel (pandas.tests.test_panel.TestPanel)

with these traces: https://gist.github.com/cb45d6f160dc17b7d458
3. Doubtful skips:

• pandas.io.tests.test_sql.*: various SKIP: Can't connect to postgresql server, although I successfully use pandas sql methods through sqlalchemy to my PostgreSQL server.
• pandas.stats.tests.*: various SKIP: no statsmodels although I do have statsmodels

@klonuo not what I mean

I am showing you where to put NEW test for a pull request to fix this issue

[klonuo]

Ah, OK. So you want me to make a test functions for above reported issues and then try to fix the issues?
If that's the idea, unfortunately I don't have any experience with writing tests. I can have a look and try tomorrow, but I don't promise results.

[jreback]

@klonuo best way to learn! just look at those tests, construct one which has this test case and fails, then make a fix.
