b58ea30ba8 * Added a facility to catch exception while capturing stdout, and deliver 
the output printed so far (to stderr), plus re-raising the exception.

f677dc1a81 * Added wpylib.py.stdout_capture as a hack tool to capture sys.stdout 
output of a given function call (and its child subroutines).

17d242213d * Added some useful functions from my pw2g_bench_MnO.py scriptlet collection: 
- wpylib.math.roundup()
  - wpylib.shell_tools.dirname2()

* file_exists_nonempty() is moved to wpylib.shell_tools.

d70bcf2149 * In text_output methods, do the required action iff self.out is not None. 2012-06-13 19:35:06 -04:00
Wirawan Purwanto
81316af285 * Added os.path-like methods: isdir, isfile, islink. 
The last one is not reliable, but is added for uniformity for the time
  being.

dcb7fa304c * Added sftp_client.put() method. 
* Added sftp_status_callback class.
 2012-05-26 08:37:01 -04:00
Wirawan Purwanto
6433e5da3c * Added prefix and suffix options for matrix_str and vector_str. 2012-05-23 00:25:42 -04:00
Wirawan Purwanto
140b3b699c * Added wpylib.interactive_tools.printstr class to facilitate logging of 
print-ed output in interactive python sessions.
 2012-05-17 12:29:30 -04:00
Wirawan Purwanto
5c72506135 * New module: wpylib.file.tee 
* Added class tee_output for splitting text output to multiple destinations.
 2012-05-14 15:48:43 -04:00
Wirawan Purwanto
ad841e0b90 * text_input.read_items(): added option end_line_match' and last_line_match' 
(mutually exclusive options) to allow the dataset reading to end upon
  encountering certain text pattern (or a more complicated match, if we
  specify a function for the option value).
  These options can be used to work with the `maxcount' option; the shortest
  of the two (maxcount records read first, or end/last_line_match finds a
  match) will end the reading of the dataset.

501552a65a * Added zip_gen() to simulate the effect of built-in zip() function, but 
implemented as a generator rather than yielding the list right away.
  This is used mainly in loops, where we don't want to generate all the
  elements due to memory concerns.
 2012-04-17 11:00:30 -04:00
Wirawan Purwanto
606214eb66 * Changing all isinstance(STUFF, str)' to isinstance(STUFF, basestring)' 
for future-proofing this code.
 2012-04-13 17:10:32 -04:00
Wirawan Purwanto
6656d3d5e3 * In module text_input: Added head() and tail() to emulate the basic 
behavior of UNIX commands with the same name.
  Output lines are already split into a list of strings.

Wirawan Purwanto
4194344891 * init_interactive() returns True if interactive session is detected; False 
otherwise.
 2012-02-16 13:45:46 -05:00

1674bfd256 * Added workaround so at least interactive python detection works 
(although not perfectly) in python <= 2.5.

f8a101fbe9 * Added comment_char option for text_input object creation. 
* Memory leak bugfix: Use instance method weakref.

5666280a45 * Alias "|" operator to "+" operator. 2012-02-09 15:02:38 -05:00
Wirawan Purwanto
3698671bed * Added: fortran_bin_file.peek_next_rec_len() to fetch the next record length 
while not advancing the read pointer to that record yet.

050e2414ef * Added faster LDdec1 for 1-based indexing. 
Tested through N=1000.
 2012-01-26 10:46:55 -05:00

d04ea8cbea * Completing jskip formula for LD that is analogous to the jskip formula for 
UD matrix format.
 2012-01-25 17:07:50 -05:00
Wirawan Purwanto
93a89d2606 * Created array indexer for "upper diagonal" indexing mode. 
Apparently I was able to create the non-iterative version of UDdec (1-based
  indices).

961a802326 * Keep a copy of my symmetric array indexer worksheet in GIT. 
Original signature:

7017fdc6af * Committing all dirty work to CVS. We are migrating to GIT. 
Beware: changes in this commit may or may not work properly.

8ebf1e422e * Add important warning. Maybe in the future we need to use operator "|" 
and append the search paths to _list_?

81e2ada60c * Allow comment character to be changed from "#" using the 
instance.comment_char attribute.

aad559d86b * Class Parameters: important change of behavior for more safety to avoid 
potential confusion.

* Detail of the important changes:

  1) by default now the function's local variables are not included in the
     lookup chain. Use _localvars_ flag if you insist on doing that; but
     be aware of the caveat (see Parameters' documentation).

  2) the default _kwparam_ and _userparam_ names are now passed on to the
     child Parameters object instead of the override values given through
     the _create_ function argument.
     Rationale: To begin with, the default names defined during the creation
     of the parent Parameters object should be used by *all* the relevant
     functions.
     Overrides should be regarded as exceptional rather than common cases.

  3) Value overrides (_kwparam_, _userparam_, etc.) in _create_ must now
     be specified in keyword=value manner rather than as positional argument.
     Rationale: Those overrides must be made conspicuous.
     The keyword=value approach also makes the code more resilient to minor
     API changes.
     All unnamed parameters are supposed to be low-priority defaults.

4aff740f55 * Parameters value lookup: use try..except EAFP rather LBYL approach. 
* Add simple checks for _p, _opts_ default arguments in case they are not
  indexable/dict-like objects. This is needed to avoid bizzare error messages
  later then the Parameters object is in use.
 2011-09-07 15:05:54 +00:00

cf46af2bc2 * Simple function rename: make_unbound_method -> make_unbound_instance_method. 2011-08-31 18:26:18 +00:00

wirawan
1e3d236b1c * Completing initial version of interactive tool support: added interactive 
mode detection (plain python, `python -i', and ipython supported),
  and my canned initialization for interactive python environment
  (like MYSELF, ARGV).

47f6bced79 * wpylib.math.linalg: Added initial module for linear-algebra convenience 
functions, objects, and submodules.

94c1651586 * wpylib.py.im_weakref: weakref for instance method. 
Copied from Linux Screen Reader project.

424a9238bb * hacks.py: Added make_unbound_method to allow general function to participate 
as hacked class methods.
 2011-06-08 15:49:04 +00:00

ceb8f35ec3 * Creating wpylib.py module to contain all python-level hacks. 
Submodules are available for specialized and more complicated hacks.
 2011-06-08 15:29:14 +00:00
wirawan
ad73b5af7f * Added set_next_proc() method to set which procedure should be called when 
"next()" method dispatcher is called.

  This approach should get rid of the problem with circular reference which
  causes the text_input instance not be erasable because of strong reference
  to `self' in `self.next.im_self'.

1bbaae135f * Added python-level advanced hack module which should hide all my dirty 
tricks here.
