In +particular when calling the function ``load()`` or ``dump()`` +temporary instances of ``Loader()`` resp. ``Dumper()`` were +created that were discarded on termination of the function. + +This way of doing things leads to several problems: + +- it is virtually impossible to return information to the caller apart from the + constructed data structure. E.g. if you would get a YAML document + version number from a directive, there is no way to let the caller + know apart from handing back special data structures. The same + problem exists when trying to do on the fly + analysis of a document for indentation width. + +- these instances were composites of the various load/dump steps and + if you wanted to enhance one of the steps, you needed e.g. subclass + the emitter and make a new composite (dumper) as well, providing all + of the parameters (i.e. copy paste) + + Alternatives, like making a class that returned a ``Dumper`` when + called and sets attributes before doing so, is cumbersome for + day-to-day use. + +- many routines (like ``add_representer()``) have a direct global + impact on all of the following calls to ``dump()`` and those are + difficult if not impossible to turn back. This forces the need to + subclass ``Loaders`` and ``Dumpers``, a long time problem in PyYAML + as some attributes were not ``deep_copied`` although a bug-report + (and fix) had been available a long time. + +- If you want to set an attribute, e.g. to control whether literal + block style scalars are allowed to have trailing spaces on a line + instead of being dumped as double quoted scalars, you have to change + the ``dump()`` family of routines, all of the ``Dumpers()`` as well + as the actual functionality change in ``emitter.Emitter()``. The + functionality change takes changing 4 (four!) lines in one file, and being able + to enable that another 50+ line changes (non-contiguous) in 3 more files resulting + in diff that is far over 200 lines long. + +- replacing libyaml with something that doesn't both support ``0o52`` + and ``052`` for the integer ``42`` (instead of ``52`` as per YAML 1.2) + is difficult + + +With ``ruyaml>=0.15.0`` the various steps "know" about the +``YAML`` instance and can pick up setting, as well as report back +information via that instance. Representers, etc., are added to a +reusable instance and different YAML instances can co-exists. + +This change eases development and helps prevent regressions. diff --git a/_doc/basicuse.rst b/_doc/basicuse.rst new file mode 100644 index 0000000..5b4f9a8 --- /dev/null +++ b/_doc/basicuse.rst @@ -0,0 +1,55 @@ +*********** +Basic Usage +*********** + +You load a YAML document using:: + + from ruyaml import YAML + + yaml=YAML(typ='safe') # default, if not specfied, is 'rt' (round-trip) + yaml.load(doc) + +in this ``doc`` can be a file pointer (i.e. an object that has the +``.read()`` method, a string or a ``pathlib.Path()``. ``typ='safe'`` +accomplishes the same as what ``safe_load()`` did before: loading of a +document without resolving unknown tags.

In that case the +element itself would normally be pushed to the next line (and older versions +of ruyaml did so). But this is +prevented from happening. However the ``indent`` level is what is used +for calculating the cumulative indent for deeper levels and specifying +``sequence=3`` resp. ``offset=2``, might give correct, but counter +intuitive results. + +**It is best to always have** ``sequence >= offset + 2`` +**but this is not enforced**.

The integration of the sources was just an initial step to +make this easier. + +adding/replacing comments +^^^^^^^^^^^^^^^^^^^^^^^^^ + +Starting with version 0.8, you can add/replace comments on block style +collections (mappings/sequences resuting in Python dict/list). The basic +for for this is:: + + from __future__ import print_function + + import sys + import ruyaml + + yaml = ruyaml.YAML() # defaults to round-trip + + inp = """\ + abc: + - a # comment 1 + xyz: + a: 1 # comment 2 + b: 2 + c: 3 + d: 4 + e: 5 + f: 6 # comment 3 + """ + + data = yaml.load(inp) + data['abc'].append('b') + data['abc'].yaml_add_eol_comment('comment 4', 1) # takes column of comment 1 + data['xyz'].yaml_add_eol_comment('comment 5', 'c') # takes column of comment 2 + data['xyz'].yaml_add_eol_comment('comment 6', 'e') # takes column of comment 3 + data['xyz'].yaml_add_eol_comment('comment 7', 'd', column=20) + + yaml.dump(data, sys.stdout) + +Resulting in:: + + abc: + - a # comment 1 + - b # comment 4 + xyz: + a: 1 # comment 2 + b: 2 + c: 3 # comment 5 + d: 4 # comment 7 + e: 5 # comment 6 + f: 6 # comment 3 + +If the comment doesn't start with '#', this will be added. The key is +the element index for list, the actual key for dictionaries. As can be seen +from the example, the column to choose for a comment is derived +from the previous, next or preceding comment column (picking the first one +found). + +Config file formats ++++++++++++++++++++ + +There are only a few configuration file formats that are easily +readable and editable: JSON, INI/ConfigParser, YAML (XML is to cluttered +to be called easily readable). + +Unfortunately `JSON <http://www.json.org/>`_ doesn't support comments, +and although there are some solutions with pre-processed filtering of +comments, there are no libraries that support round trip updating of +such commented files. + +INI files support comments, and the excellent `ConfigObj +<http://www.voidspace.org.uk/python/configobj.html>`_ library by Foord +and Larosa even supports round trip editing with comment preservation, +nesting of sections and limited lists (within a value). Retrieval of +particular value format is explicit (and extensible). + +YAML has basic mapping and sequence structures as well as support for +ordered mappings and sets. It supports scalars various types +including dates and datetimes (missing in JSON). +YAML has comments, but these are normally thrown away. + +Block structured YAML is a clean and very human readable +format. By extending the Python YAML parser to support round trip +preservation of comments, it makes YAML a very good choice for +configuration files that are human readable and editable while at +the same time interpretable and modifiable by a program. + +Extending ++++++++++ + +There are normally six files involved when extending the roundtrip +capabilities: the reader, parser, composer and constructor to go from YAML to +Python and the resolver, representer, serializer and emitter to go the other +way. + +Extending involves keeping extra data around for the next process step, +eventuallly resulting in a different Python object (subclass or alternative), +that should behave like the original, but on the way from Python to YAML +generates the original (or at least something much closer). + +Smartening +++++++++++ + +When you use round-tripping, then the complex data you get are +already subclasses of the built-in types. So you can patch +in extra methods or override existing ones.

One +explanation you get by looking at what someone would need to do to make this +available if it weren't there already. Apart from subclassing the ``Serializer`` +and providing a new ``dump`` method, which would ten or so lines, another +**hundred** lines, essentially the whole ``dumper.py`` file, would need to be +copied and to make use of this serializer. + +The fact is that one should normally be doing ``round_trip_dump(dict(a=1, b=2)), +sys.stdout)`` and do away with 90% of the cases for returning the string, and +that all post-processing YAML, before writing to stream, can be handled by using +the ``transform=`` parameter of dump, being able to handle most of the rest.
