2015-05-20dialyzer: Document dialyzer:gui() option 'check_plt'Hans Bolinder
* Mention the option 'check_plt' among gui() options. * No longer check a PLT twice when the analysis type is 'plt_check'. * No longer raise a case_clause error when checking a PLT finds warnings. Thanks to James Fish.
2015-01-14dialyzer: Introduce module local suppression of warningsHans Bolinder
The -dialyzer() attribute can be used for suppressing warnings in a module by specifying functions or warning options. It can also be used for requesting warnings in a module.

2014-03-20Return warnings for unknown types and functions in Erlang ModeHans Bolinder
The warnings about unknown types and functions are now returned when calling Dialyzer from Erlang, in particular from an escript. When calling Dialyzer from the command line the warnings about unknown types and functions are output last as before; and when using the GUI the warnings are displayed in a pop-up window, as before.
2014-01-21[dialyzer] Re-work the handling of opaque typesHans Bolinder
It is now OK to inspect and modify the internals of opaque types within the scope of the module. The contracts are used for decorating types with opaqueness when it is harmless to do so. The opaqueness is propagated by the typesig module and also by the dataflow module. A lot of details have been fixed or updated. In particular the modules erl_types and erl_bif_types have been modified extensively. The version in vsn.mk has been updated to 2.7. The reason is a modification of #opaque{} in erl_types. Dialyzer seems to be about five percent slower than it used to be.
2013-11-13Remove the GS-based GUI of DialyzerKostis Sagonas
R17 will come without support for 'gs' so the old gs-based GUI of dialyzer has been removed.

2013-03-06Include module, function and arity in Dialyzer's "overlapping domain" warningsMagnus Henoch
The function name can give information that the line number doesn't, for example when using a parse transform that creates new functions.

2012-09-24dialyzer: Do not output warnings for unused funsHans Bolinder
Dialyzer no longer outputs warnings for unused anonymous functions ("funs"). Warnings are still output for unused functions. Funs in functions with -nowarn_unused_function attributes generated warnings for unused functions. Unused list comprehensions also generated warnings for unused funs.

* sa/dialyzer-fix-guards: Fix warnings about guards containing not Fix errors in the handling of 'and'/'or' guards Cosmetic changes OTP-9099
2011-01-20Add a --fullpath option to DialyzerKostis Sagonas
This change adds a --fullpath option to Dialyzer, which makes the warning messages contain the full path of the corresponding file. Original patch submitted by Magnus Henoch (legoscia) on 15/9/2010 and cooked to death in the 'pu' branch all this time. The patch was essentially correct and most of it has been used as is, but there have been some changes to make the code slightly prettier, avoid some code duplication, and add documentation to dialyzer's doc files and to its help message.
2011-01-18Fix warnings about guards containing notStavros Aronis
The wording of warnings about unsatisfiable guards that used 'not' was incorrect (the 'not' was not mentioned and it appeared as "Guard test is_atom(atom()) can never succeed").
2010-11-30dialyzer: Add support for multiple PLTsMaria Christakis
This new feature is able to take multiple PLTs, merge them during the start of the analysis, and work from there. This works provided that the PLTs do not have a module with the same name appearing in more than one PLT. The PLTs are created in the usual way: dialyzer --build_plt --output_plt PLT_1 FILES_TO_INCLUDE ... dialyzer --build_plt --output_plt PLT_N FILES_TO_INCLUDE and then can be used in either of the following ways: dialyzer FILES_TO_ANALYZE --plts PLT_1 ... PLT_N or: dialyzer --plts PLT_1 ... PLT_N -- FILES_TO_ANALYZE (Note the -- delimiter in the second case)

2010-11-09dialyzer: Speed up analysis of nested list comprehensionsKostis Sagonas
Nested list comprehensions are translated into strongly connected funs but dialyzer ignored this. This meant that self-recursive analysis was normally executed for each fun and the whole fixpoint took some time to calculate. This patch adds every fun found in constraint generation to the SCC that is under analysis and then solves the SCC as a whole. Possible issues: - The returned dict contains more entries than usual. This triggered a bug in contract checking that is dealt with is this patch as well (dialyzer_contracts.erl). - As it's not easy to tell apart real fun SCCs from simple funs it performance might be hampered in the simple funs case. While doing these changes, also added and strengthened some specs. In addition, incorporated a modified patch by Ahmed Omar that fixes a bug in dialyzer_analysis_callgraph module that kept the files of only one selected directory in dialyzer's GUI.
