    search space into a single dict.
  - The _flatten_ flag will flatten the input dicts and keyword-based
    parameter (in the __init__() method only) in the expected order of
    priority (where the first found keyword is the most overriding one)
    into a single search dict.
 2013-04-16 14:06:26 -04:00
Wirawan Purwanto 8d32c2c067 * Parameters: if _flatten_ is enabled, must flatten in reverse order to 
give the firstly mentioned dict the priority.
 2013-04-16 11:55:18 -04:00
Wirawan Purwanto 254aaca622 * Added tester for active Parameters value. 2013-04-11 14:38:04 -04:00

  being.
 2012-06-03 20:35:40 -04:00
Wirawan Purwanto dcb7fa304c * Added sftp_client.put() method. 
* Added sftp_status_callback class.
 2012-05-26 08:37:01 -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.
 2012-04-17 11:03:29 -04:00
Wirawan Purwanto 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.
 2012-03-19 16:53:23 -04:00
Wirawan Purwanto 41079fd92c * sugar: Added is_iterable(). 2012-03-19 11:57:19 -04:00
Wirawan Purwanto 14303979f1 * Recorded down some notes/caveat for init_interactive(). 2012-02-16 13:53:58 -05:00
Wirawan Purwanto 4194344891 * init_interactive() returns True if interactive session is detected; False 
otherwise.
 2012-02-16 13:45:46 -05:00
Wirawan Purwanto 1674bfd256 * Added workaround so at least interactive python detection works 
(although not perfectly) in python <= 2.5.
 2012-02-16 13:32:55 -05:00
Wirawan Purwanto f8a101fbe9 * Added comment_char option for text_input object creation. 
* Memory leak bugfix: Use instance method weakref.
 2012-02-15 23:02:11 -05:00
Wirawan Purwanto 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.
 2012-01-30 16:04:17 -05:00
Wirawan Purwanto 050e2414ef * Added faster LDdec1 for 1-based indexing. 
Tested through N=1000.
 2012-01-26 10:46:55 -05:00
Wirawan Purwanto 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).
 2012-01-24 17:32:39 -05:00
Wirawan Purwanto 961a802326 * Keep a copy of my symmetric array indexer worksheet in GIT. 
Original signature:
    -rw-r--r-- 1 wirawan0 wirawan0 1380 2010-04-27 15:55 symmetrix-array-index.py
    b873ece4610483b3cd5290c6ddbc7426  symmetrix-array-index.py
 2012-01-24 17:28:10 -05:00
wirawan 7017fdc6af * Committing all dirty work to CVS. We are migrating to GIT. 
Beware: changes in this commit may or may not work properly.
 2011-10-06 19:15:05 +00:00
wirawan 8ebf1e422e * Add important warning. Maybe in the future we need to use operator "|" 
and append the search paths to _list_?
 2011-09-19 20:06:45 +00:00
wirawan 81e2ada60c * Allow comment character to be changed from "#" using the 
instance.comment_char attribute.
 2011-09-16 21:21:23 +00:00
wirawan 3f38cbfb34 * Allow printing of numpy.matrix objects. 2011-09-13 21:50:16 +00:00
wirawan 6fb10829e0 * Added Parameters._get_() method. 2011-09-12 21:58:43 +00:00
wirawan 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.
 2011-09-09 18:58:48 +00:00
wirawan 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
wirawan 1181a7e516 * Add descriptive error message. 2011-09-07 15:04:15 +00:00
wirawan ceeafa811a * Added str_snippet() from MnO ipython script. 2011-09-07 15:03:54 +00:00
wirawan c675077620 * Introducing self.lineno counter for line numbers (including the blanks 
and comment lines).
 2011-09-05 19:09:21 +00:00
wirawan 3f3c49df94 * Added file mode for file creation (default: "w"). 2011-09-02 15:07:47 +00:00
wirawan cde48ef8de * wpylib.datetime: Date/time related module. 2011-09-01 15:34:03 +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).
 2011-07-18 15:48:52 +00:00
wirawan 47f6bced79 * wpylib.math.linalg: Added initial module for linear-algebra convenience 
functions, objects, and submodules.
 2011-07-14 19:00:59 +00:00
wirawan 94c1651586 * wpylib.py.im_weakref: weakref for instance method. 
Copied from Linux Screen Reader project.
 2011-06-08 15:50:07 +00:00
wirawan 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
wirawan 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'.
 2011-06-03 21:34:32 +00:00
wirawan 1bbaae135f * Added python-level advanced hack module which should hide all my dirty 
tricks here.
 2011-06-03 21:31:59 +00:00
wirawan 90c4f1b50b * Added vector_str and matrix_str generic function to print a matrix/vector 
in space-seprated string format.
  The output is mainly for human consumption, not for machine re-reading
  (although it is possible to do so, in general).
 2011-06-03 18:24:00 +00:00
wirawan 9e1c6f5868 * Commenting out the verbose printout. I think the module is robust now. 2011-05-12 14:51:02 +00:00
wirawan 90f1603499 * Added text_output as a converse facility to print out text stream to 
a file.
  Useful for a shortened output statements in the code, and also for
  reroutable output (to stdout? to file? to both?) and flexible output
  kind.
 2011-05-11 20:28:51 +00:00
wirawan 0531e4e511 * Add documentation for file_table. Add note for future hash: SHA1,256,... 2011-04-26 15:28:37 +00:00

(err) field!
 2011-03-10 20:17:55 +00:00
wirawan 2a30c20a79 * Added dict_islice to support slicing while ignoring non-existing keys 
in the source dict.
 2011-03-10 20:16:58 +00:00
