* Remove $versionGravatar Fabian Homborg2016-05-26
| | | | | It's too generic a name - which both does not communicate what it is and prevents someone else from using it.
* tty driver ignore lnext (\cV) and werase (\cW)Gravatar Kurtis Rader2016-05-25
| | | | | | | | | | Configure the tty driver to ignore the lnext (\cV) and werase (\cW) characters so they can be bound to fish functions. Correct the `fish_key_bindings` program to initialize the tty in the same manner as the `fish` program. Fixes #3064
* kill: Remove xsel integrationGravatar Fabian Homborg2016-05-25
| | | | | | | Overwriting the user's clipboard by default is annoying and contributors don't use it. This is better served via an explicit binding that calls e.g. `xsel`.
* add option to modify script being restyledGravatar Camille Scholtz2016-05-22
| | | | | | This change allows the user to specify the script name on the CLI in addition to being redirected from stdin. It also adds a `-w` flag to write the modified script to the original file.
* fix building on CygwinGravatar Kurtis Rader2016-05-19
| | | | | | | Cygwin still doesn't support any of the backtrace functions. Also, remove a spurious newline from a debug message. Fixes #2993
* make fish buildable on OS X Snow LeopardGravatar Kurtis Rader2016-05-19
| | | | | | | | | | | | | I noticed that the `test_convert()` function was randomly failing when run on OS X Snow Leopard. I tracked it down to the `mbrtowc()` function on that OS being broken. Explicitly testing for UTF-8 prefixes that identify a sequence longer than four bytes (which the Unicode standard made illegal long ago) keeps us from having encoding errors on those OS's. This also makes the errors reported by the `test_convert()` function actually useful and readable. Lastly, it makes it possible to build fish on OS X Snow Leopard.
* move convert_digit from fallback to commonGravatar David Adam2016-05-18
| | | | It's not required as part of fallback functions any more.
* fallback: drop fallbacks for C99/C++0x wide character functionsGravatar David Adam2016-05-18
| | | | | | | | Drops configure check for wcsdup, wcslen, wcscasecmp, wcsncasecmp, wcwidth, wcswidth, wcstok, fputwc, fgetwc, and wcstol. Drop the fallback implementations of these on non-Snow Leopard platforms. Work on #2999.
* fallback: remove fwprintf and friends fallbacksGravatar David Adam2016-05-18
| | | | | | | All modern operating systems implement fwprintf, including NetBSD (which introduced them in 2005). Work on #2999.
* fallback: remove sysconf fallbackGravatar David Adam2016-05-18
| | | | | | | sysconf was introduced in IEEE Std 1003.1-1988 (POSIX.1) and exists on every system I can find. Work on #2999.
* configure: drop fwprintf testGravatar David Adam2016-05-18
| | | | | | | | | | | fwprintf would segfault on DragonFly BSD 1.4.0, released in January 2006. This was fixed by DragonFly BSD 1.4.4, released in April 2006. It seems unlikely that anyone is still running a ten-year-old, unsupported version, and hoping that fish will continue to build. I've checked this in virtual machines. Work on #2999.
* configure: drop tests for ancient platformsGravatar David Adam2016-05-18
| | | | Work on #2999.
* add (or restore) config.h to all filesGravatar David Adam2016-05-18
| | | | | | | | The autoconf-generated config.h contains a number of directives which may alter the behaviour of system headers on certain platforms. Always include it in every C++ file as the first include. Closes #2993.
* make debug() output more usefulGravatar Kurtis Rader2016-05-17
| | | | | | | | | | This change does several things. First, and most important, it allows dumping the "n" most recent stack frames on each debug() call. Second, it demangles the C++ symbols. Third, it prepends each debug() message with the debug level. Unrelated to the above I've replaced all `assert(!is_forked_child());` statements with `ASSERT_IS_NOT_FORKED_CHILD()` for consistency.
* trivial fix to fish_tests.cppGravatar Kurtis Rader2016-05-16
| | | | | | | Fix a minor bogosity I noticed while building fish on OS X Snow Leopard. It's technically not a bug because only old compilers complain about the original statement but this change makes the one line this changes consistent with the rest of the fish code.
* add `function --shadow-builtin` flagGravatar Kurtis Rader2016-05-14
| | | | | | | | | | | | | | It's currently too easy for someone to bork their shell by doing something like `function test; return 0; end`. That's obviously a silly, contrived, example but the point is that novice users who learn about functions are prone to do something like that without realizing it will bork the shell. Even expert users who know about the `test` builtin might forget that, say, `pwd` is a builtin. This change adds a `--shadow-builtin` flag that must be specified to indicate you know what you're doing. Fixes #3000
* rename get_is_interactive and remove stupid testGravatar Kurtis Rader2016-05-14
| | | | | | I'm doing this as part of fixing issue #2980. The code for managing tty modes and job control is a horrible mess. This is a very tiny step towards improving the situation.
* enhance the key_reader programGravatar Kurtis Rader2016-05-10
| | | | | | | | | | The original `key_reader` program was useful but didn't do much that `xxd` or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by default. This change adds features that make it superior to those programs for decoding interactive key presses and makes it a first-class citizen like the `fish_indent` program that is always available. Fixes #2991
* restyle the key_reader sourceGravatar Kurtis Rader2016-05-10
|
* fix fork debug printf() callsGravatar Kurtis Rader2016-05-05
| | | | | | | | The fork (create new process) related debugging messages rely on an undocumented env var and use `printf()` rather than `debug()`. There are also errors in how the fork count is tracked that this fixes. Fixes #2995
* lint: low hanging fruit in history.cppGravatar Kurtis Rader2016-05-05
|
* lint: screen.cpp low hanging fruitGravatar Kurtis Rader2016-05-04
| | | | | The remaining lint work to be done on screen.cpp will require refactoring several functions that are way too large and complex.
* lint cleanup: eliminate "redundant" errorsGravatar Kurtis Rader2016-05-04
| | | | | This removes some pointless parentheses but the primary focus is removing redundancies like unnecessary "else" clauses.
* eliminate "useless parentheses" lint errorsGravatar Kurtis Rader2016-05-03
| | | | | | | Some `oclint` errors regarding "useless parentheses" are meaningfull. But the vast majority are bogus in as much as removing the parentheses reduces readability. So fix a few of the egregious uses and otherwise suppress that error.
* add missing fallback declarationsGravatar Kurtis Rader2016-05-03
| | | | Fixes #2993
* restyle switch blocks to match project styleGravatar Kurtis Rader2016-05-03
| | | | | | | | | | | | | | | I missed restyling a few "switch" blocks to make them consistent with the rest of the code base. This fixes that oversight. This should be the final step in restyling the C++ code to have a consistent style. This also includes a few trivial cleanups elsewhere. I also missed restyling the "complete" module when working my way from a to z so this final change includes restyling that module. Total lint errors decreased 36%. Cppcheck errors went from 47 to 24. Oclint P2 errors went from 819 to 778. Oclint P3 errors went from 3252 to 1842. Resolves #2902.
* restyle remaining modules to match project styleGravatar Kurtis Rader2016-05-03
| | | | | | | | | For this change I decided to bundle the remaining modules that need to be resytyled because only two were large enough to warrant doing on their own. Reduces lint errors from 225 to 162 (-28%). Line count from 3073 to 2465 (-20%). Another step in resolving issue #2902.
