d7a65386a3 * Fortran binary file: Added bulk_read_array1 method for quick reading of 
array of (uniform-type) Fortran records.

723f1a4fc1 * Added __enter__/__exit__ method for use with python 2.5's "with" statement. 2014-08-02 21:32:34 -04:00

f49d166a77 * wpylib.iofmt.fortbin: Added fortran_types class to manage and analyze 
Fortran datatypes.

  First edition contains tool to estimate the size of datatypes,
  and size of file records (or sequence of records).

d70bcf2149 * In text_output methods, do the required action iff self.out is not None. 2012-06-13 19:35:06 -04:00

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.

606214eb66 * Changing all isinstance(STUFF, str)' to isinstance(STUFF, basestring)' 
for future-proofing this code.

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.

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

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.

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

c675077620 * Introducing self.lineno counter for line numbers (including the blanks 
and comment lines).

3f3c49df94 * Added file mode for file creation (default: "w"). 2011-09-02 15:07:47 +00:00

3b522de2d6 * Added text_input.close() method. 2011-08-31 20:28:30 +00:00

7d37c0b6ba * Internal upgrade to factor out reusable parts (for future upgrades). 2011-08-31 20:27:31 +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'.

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.

96d1f9afd7 * Upgrade to allow reading complex-valued data directly. 
Please see the documentation of text_input.read_items for more detail.

cae9cabdea * Simple text input reader. Imported from pyqmc.utils.text_input . 2010-09-27 19:54:05 +00:00

69592e9a8f * Added writing facility. Still largely untested. 2010-02-19 18:39:17 +00:00

21e85704aa * Initial version of Fortran binary file reader. 
Later a writing facility can be added as well.
* Note that this module is intended only for reading/writing
  Fortran-generated files.
  It is not recommended for any other purpose because of its terrible feature:
  no metadata, no description whatsoever.
