| | | | | | | | | | | | | This patch introduces 2 main changes: - COMPOUNDABLES includes the negated version of the 'underline', 'italic'... so now it includes also 'no_italic' and similar. - split_into_formatters considers also the 'no' prefix. With this changes expressions like: t.red_no_underline t.no_italic_bright_yellow work as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | as explained in the comments above the decode().encode() wrapper, certain terminal kinds, such as 'avatar' or 'kermit' emit 8-bit bytes that are not legal utf-8 tender. this issue is resolved by encoding these values as latin1, which leaves their values unmolested. This is exaplified by a gist: https://gist.github.com/jquast/5649654 If you don't believe me, try kind='kermit' or kind='avatar', along with t.cup(n, n). Unfortunately, the state of the test cases in the master branch (issue #33) does not allow to add a test case in this branch until that one is pulled to master. Hell, I'll go ahead and make a third (and final) pull request for that one,
* | Remove fallback to 24x80, and fix docstring formatting.Erik Rose2013-11-051-7/+11
| | | | | | There are some advantages to falling back to 24x80: for example, the ability to easily render output based on height and width when being piped through `less`. However, that's a backward incompatible change--we explicitly documented the None return values in earlier versions--so I don't want to make it lightly. Reverting it for now because I want to get the unquestionable parts of this merged in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | avoid calling tparm when self.does_styling is False, which resolves issues with attempting to use things (such as nosetests progressive) where the terminal is not a tty. its also a "pokemon exception" and is emitted for a good reason, we certainly should not be calling tparm without calling setupterm() first !

* | implement height and width fallback for non-ttyjquast2013-11-041-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | once the height and width test is resolved to actually test, we notice that running `nosetests 2>&1 | less' & etc. will fail: the ioctl for TIOCGWINSZ fails for non-ttys (such as used by travis CI). So, we fall-through to the LINES, COLUMNS environment variables, with default values of (24, 80). (24, 80) has been a fairly standard screensize for IBM PC-DOS and Apple ][ (beginning with the 80-column character card), and C128. It is also the default for xterm, and many classic terminals (such as a vt220) or emulating terminals (such as telix), or bulletin board servers (such as teleguard) where a 'status line' is also present. In reality, these screens are capable of *25* lines, but the 25th line is reserved for the status line. Irregardless, non-zero must be returned for 'height' and 'width' properties, as a value of 0 may become a "divide by zero" error for mathematical operations that make use of the terminal height or width in scripts that the user may chose to pipe to 'less -r' or some such. In these situations, even though a value is returned, operations such as 'move(x, y)' would still become 'stripped' due to 'is_a_tty' becoming False, so there is no actual harm in providing a terminal size that is not legal.
