./devel/flex, Fast clone of lex(1), the lexical scanner generator

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.6.4, Package name: flex-2.6.4, Maintainer: pkgsrc-users

flex is a tool for generating scanners: programs which recognized
lexical patterns in text. flex reads the given input files, or its
standard input if no file names are given, for a description of a
scanner to generate. The description is in the form of pairs of
regular expressions and C code, called rules. flex generates as
output a C source file, lex.yy.c, which defines a routine yylex().
This file is compiled and linked with the -lfl library to produce an
executable. When the executable is run, it analyzes its input for
occurrences of the regular expressions. Whenever it finds one, it
executes the corresponding C code.

Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

Log message:
flex: Remove bash dependency.

This was hidden behind a broken test section, and causing circular dependency
problems on some OS with bash -> bison -> flex -> bash.  The GNU make
requirement is still valid, but the test suite no longer requires bash.

Reported by Alver on IRC.

Log message:
Add workaround for fixing build on Linux

See https://github.com/westes/flex/issues/241
The problem is fixed in master branch and the workaround could be removed
in the next version update.

Log message:
Update flex to 2.6.4.

Upstream news:

* Noteworthy changes in release 2.6.4 (2017-05-06) [stable]

** build

*** The indent target now knows about flex's new (as of 2.6.0)
    layout. The indent rules it would apply are not correct and do
    need to be fixed.

*** The files included in the flex distribution are now built by the
    version of flex that is included in the distribution.

*** The configure script has a better idea of which headers are
    required to build flex. It will also error when missing functions
    are detected.

*** We have lowered the versions of automake and gettext that
    configure.ac lists as required for building flex. In autogen.sh,
    we now check for how to call libtoolize and use what we find in
    the rest of the script.

*** Since files in lib/ are picked up as needed by src/, we no longer
    generate a Makefile for that directory.

*** Flex can be cross compiled.

** documentation

*** Some typos were removed from the manual.

** scanner

*** Some minor performance enhancements.

*** We honor user defined yy_* macros again. We are also more careful
    to not leak macro definitions into header files.

*** A number of portability fixes were introduced so building flex is
    more reliable on more platforms. Additionally, outdated function
    calls were removed.

*** When building the flex executable itself, %# comments from
    flex.skl are removed when generating the C source code array. This
    reduces the size of flex.

** test suite

*** All scripts in the test suite are now run by $(SHELL) and the
    needed portability fixes have been included.

*** Test suite dependencies are handled much better. This only matters
    if you are actively developing flex or its test suite.

*** Tests that depend on platform dependent features now properly skip
    when those platforms are not present.

*** When running "make check", you can now pas V=0 to silence more of
    the build. This is useful when you're less connncerned about the
    details of building and linking the test programs themselves.
