config.h will have either define ENABLE_NLS or not define it. If it is
not defined we get a -Wundef warning due to using #if with an
undefined macro
|
| |
|
|
|
|
| |
The function fileno() is defined by POSIX. When flex would otherwise not provide that feature macro, we define it.
Fixes #263

Use one from <stdlib.h> instead because that is more portable.

This would, e.g. define _GNU_SOURCE in config.h, enabling the
reallocarray() prototype in glibc 2.26+ on Linux systems with that
version of glibc.
Fixes #241.

config.h may define macros that alter the API of the standard library
funtions, and so it should be included before any other standard
header, even before the skeleton's standard header inclusion.
For example: config.h may #define _GNU_SOURCE that would expose the
reallocarray() prototype from <stdlib.h> on glibc 2.26+ systems. If we
include <stdlib.h> before config.h, reallocarray() would not be
available for use in lex file since the second include doesn't help
due to header guard.
For now our config.h might `#define malloc rpl_malloc` -- this
substitution must work before including stdlib.h, or else the compiler
will complain about missing prototypes, and may result in incorrect
code in scan.l (gcc warning: return makes pointer from integer without
a cast [-Wint-conversion]).
Fixes #247.

These are wrappers around automake- and libtool-generated targets,
allowing users to build libfl only, without the main flex program.
See GH-256 for discussion.

There's no need to include any header when linking with `-lfl`.

Don't use program_name in the description of -T/--trace or -V/--version
option. It's ugly when user invokes flex with a long path like
"/home/username/tools/bin/my-custom-built-flex".
This solution is not long term. If possible, the help text should be
modified so that the "flex" name is no longer needed below the first
"Usage:" line. All translations of help text will need to be updated
as well.
|
| |
|
|
| |
"%s %s\n" is not translatable

There's no technical need of stripping path from program_name. I think
the users should be fine if they see the path they use to invoke flex
is diagnostic messages and help texts.
Yes, users will see "Usage: ../flex [OPTIONS]..." now if they invoke
flex with the path "../flex".
The --version output has been changed so that the name field will be
always "flex" or "flex++". If the flex program has been renamed to
"lex" (for compatibility or other reason) this will allow identifying
the implementation name ("flex"). (And it's a recommended practice in
GNU Coding Standards)

In skeleton files comments are indicated by leading `%#` and when
directly read in using `flex -S <skeleton.skl>` they should be
ignored. Example: `flex.skl`.
Amending commit 2f21edac99b5efc432417233e6e53326d630e08f which removed
this conditional branch.

Using regex_t regex_blank_line is *slow*.
|
| |
|
|
|
|
| |
It's simply to return (regexec(®ex_blank_line, str, 0, NULL, 0) == 0);
The reason for encapsulation is to allow replacing this with a
non-regex method if necessary.

**Issue:**
Scanner generation leaks memory for transition tables when invoked
without `--tables-file` option.
**Root cause:**
`gentabs` function has different memory acquire/release conditions.
**Solution:**
Reclaim memory at the same scope where it was alloacated.

**Issue:**
Scanner postprocessing leaks memory during correction of `#line`
directives values and generation of C header file.
**Root cause:**
`filter_fix_linedirs` and `filter_tee_header` functions do not
dispose allocated memory.
**Solution:**
Automatically reclaim affected memory by allocating it on stack
insted of heap. Stack allocation should not be a problem as its
only 512 bytes and there is no recursive calls.

In a directory containing multiple scanners, we want to allow
specifying the name of the backup file else the backup files will be

NetBSD had a crash during build. Since the provided substitute for
reallocarray() wasn't working, use NetBSD's reallocarr(). Let
configure choose that function whenever it is available. Use
reallocarray if available. Still fallback if neither is available.

A #line pre-processor directive specifies the line number and source
file of the following lines. If the source file _is_ the current file,
the line number should be that of the line following the directive. So
the specified line number should be the current line number plus 1.
