* Updated include directive and added test cases.experimental/gsoc/astVishal Gupta2018-08-0411-26/+70
| | | | | | | After parsing the file given in the include directive, the tree generated is printed to standard input using Data::Dumper and this is evaled in the program having include directive. As a result the tree gets appended to the parent AST.
* Added case for testing recursive automake at multiple depthVishal Gupta2018-08-042-1/+3
|
* Updated make install to make parser work from any directoryVishal Gupta2018-08-046-37/+53
| | | | | | | | | | *Added parser.pl to /usr/bin so that it can work from any directory Modules are copied to /tmp/parser and the location is updated in parser.pl. This is for development purpose only and it can be changed in future. *Added a basedir variable so that recursive automake can work to arbitrary depth
* Added support for include directiveVishal Gupta2018-07-255-33/+49
| | | | Added lexer and parser support for include directive to handle fragements.
* Subdirs implementationVishal Gupta2018-07-128-37/+40
| | | | | | Added support to recursively call parser.pl on the directories defined in SUBDIRS variable. Added test case.
* Updated parser to tokenize and parse line by line.Vishal Gupta2018-07-066-48/+46
| | | | | | Lexer tokenizes the current line whenever it is called by parser. "end" token is returned when EOF is encountered. Currently assumes that newline is their before EOF.
* Added support for SUBDIRS and nested if/else statementVishal Gupta2018-07-026-27/+64

* Implemented Lexer, Parser and AST module.vishalgupta972018-05-269-0/+368
| | | | | | | | | | | | | The grammar seperates the automake rule into left side and right side. It divides the left side according to the primaries like PROGRAMS, LIBRARIES. * Lexer.pm: Lexer module.

* automake: Don't rely on List::Util to provide 'none'Mathieu Lirzin2018-03-081-1/+19
| | | | | | | | | | | | | This change fixes automake bug#30631. This removes the use of List::Util which is not supported by Perl 5.6, by reimplementing the 'none' subroutine. * lib/Automake/General.pm (none): New subroutine. * bin/automake.in (handle_single_transform): Use it. * t/pm/General.pl: New test. * t/list-of-tests.mk (perl_TESTS): Add it. * NEWS: Update.

* Prefer https: URLsPaul Eggert2017-09-1922-22/+22
| | | | | | | | | | | | | | | | | | | | | In Gnulib, Emacs, etc. we are changing ftp: and http: URLs to use https:, to discourage man-in-the-middle attacks when downloading software. The attached patch propagates these changes upstream to Automake. This patch does not affect files that Automake is downstream of, which I'll patch separately. Althouth the resources are not secret, plain HTTP is vulnerable to malicious routers that tamper with responses from GNU servers, and this sort of thing is all too common when people in some other countries browse US-based websites. See, for example: Aceto G, Botta A, Pescapé A, Awan MF, Ahmad T, Qaisar S. Analyzing internet censorship in Pakistan. RTSI 2016. https://dx.doi.org/10.1109/RTSI.2016.7740626 HTTPS is not a complete solution here, but it can be a significant help. The GNU project regularly serves up code to users, so we should take some care here.

* automake: account for perl hash order randomizationStefano Lattarini2013-10-311-7/+7
| | | | | | | | | | | | | | | | | | | | | Try to explicitly order the keys of some perl hashes when looping on them to do sanity/correctness checks and possibly display warning messages; this should ensure a more reproducible output. Not really a big deal, but I prefer to keep the order of such output reproducible if possible. Issue revealed by spurious testsuite failures with perl 5.18, as reported in automake bug#14891. See also: <http://search.cpan.org/dist/perl-5.18.0/pod/perldelta.pod#Hash_randomization> <http://onionstand.blogspot.ie/2012/12/are-you-relying-on-hash-keys-being.html> * lib/Automake/Variable.pm (variables): Explicitly order the values of the returned Automake::Variable instances.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes automake bug#14560: when two or more user-defined suffix rules were present in a single Makefile.am, automake would needlessly include definition of some make variables related to C compilation in the generated Makefile.in. * automake.in (handle_languages): Fix logic to decide whether or not to include definitions of C compilation related variables in the generated Makefile.in: instead of doing so when two or more user-defined suffix rules are seen (which is a completely bogus criterion), do so when two or more compiled languages are used. * lib/Automake/Rule.pm (suffix_rules_count): Remove as no longer used.

In fact, if the same incompatible version number is specified in AUTOMAKE_OPTIONS in both (say) 'Makefile.am' and 'sub/Makefile.am', we want each such erroneous usage reported separately, rather than just the first time it is encountered (as we'd expect to happen when "uniq_scope => US_GLOBAL" is used).
