Parrot support on Exuberant Ctags

Parrot and Ctags

As you know, parrot itself has very common editors support. Some common settings, syntax, color scheme and even tags file can generated with running "make" on parrot_src/editor directory.

$ make vi-tags
$ make vi

But, unfortunately, that tags files can do resolve to c source files that make parrot itself, so any languages wrote in parrot features such like 'pir' doesn't understand how to works with it.

So, I added parrot.c to Exuberant Ctags and published on my github.

*This is a very basic support for parrot ctags, yet*

$ git clone git://github.com/lateau/exuberant-ctags.git
$ cd exuberant-ctags
$ ./configure
$ make -j
$ su -c 'make install'     # install if you want
$ ./ctags --list-languages
...
parrot
...
$./ctags --list-kinds=parrot
s subroutine
r rule
t token

Supported files:

*.pir
*.pasm
*.pg

Kinds:

s subroutine
r rule

t token

Usage:

$ cd rakudo
$ ctags -R -exclude=.git --lang-map=parrot:+.pir.pasm.pg

How to use with tlist.vim

You can also enable TagList in vim. Just add bellow code to taglist.vim around line 430.

" parrot
s:tlist_def_parrot_settings = \
   'parrot;s:subroutine;r:rule;t:token'

Compiling Ruby1.9 with SunCC on OpenSolaris

Today, I compiled snapshot of ruby on my OpenSolaris machine. It's so smoothly gone and then I could try some new features of ruby1.9.2 on developing.

First of all, very important thing is installation of SunCC via IPS. It is included i n Sun Studio built on Netbeans.

$ pfexec pkg install pkg:/sunstudio12u1
$ CC='/opt/sunstudio12u1/bincc' CFLAGS='-Xa' ./configure --enable-pthread

That's all.
