jsparsenodetree.c part2
これは下記のurlの内容の設定例です。
探したところ、javascriptを分割する場合には
http://siliconforks.com/doc/parsing-javascript-with-spidermonkey/
http://ido.nu/kuma/2009/10/22/spidermonkey-parsenode-to-json/
http://www.mozilla-japan.org/js/spidermonkey/
が良いように見受けられます。
各々のサイトから example.c jsparsenodetree.c js-1.8.0-rc1.tar.gz をダウンロードします。
$ tar xvzf js-1.8.0-rc1.tar.gz
$ cd js/src/
$ cp -i /tmp/jsparsenodetree.c .
const char * TOKENS[] を修正します。
$ gcc -o jsparsenodetree -Wall -Wno-format -g -DXP_UNIX -DSVR4 -DSYSV -D_BSD_SOURCE -DPOSIX_SOURCE -DDARWIN -DX86_LINUX -DDEBUG -DDEBUG_kuma -DEDITLINE -I./Linux_All_DBG.OBJ -DHAVE_VA_COPY -DVA_COPY=va_copy -L./Linux_All_DBG.OBJ -ljs -Wl,-rpath,'$ORIGIN/Linux_All_DBG.OBJ' jsparsenodetree.c
動作しました。
$ cat /tmp/good.js
print('hello world');
$ ./jsparsenodetree /tmp/good.js
{
"node": "LIST",
"token": "LC",
"list": [
{
"node": "UNARY",
"token": "SEMI",
"kid": {
"node": "LIST",
"token": "LP",
"list": [
{ "node":"NAME", "token":"NAME", "identifier":"print"},
{ "node":"NULLARY", "token":"STRING", "opcode":"string", "text": "hello world"}
]
}
}
]
}
php の token_get_all($buf); に似た感じになります。
$ ./jsparsenodetree /tmp/good.js | php -r '$buf = file_get_contents("php://stdin"); var_export(json_decode($buf));'
stdClass::__set_state(array(
'node' => 'LIST',
'token' => 'LC',
'list' =>
array (
0 =>
stdClass::__set_state(array(
'node' => 'UNARY',
'token' => 'SEMI',
'kid' =>
stdClass::__set_state(array(
'node' => 'LIST',
'token' => 'LP',
'list' =>
array (
0 =>
stdClass::__set_state(array(
'node' => 'NAME',
'token' => 'NAME',
'identifier' => 'print',
)),
1 =>
stdClass::__set_state(array(
'node' => 'NULLARY',
'token' => 'STRING',
'opcode' => 'string',
'text' => 'hello world',
)),
),
)),
)),
),
))
また
$ pecl list-all|grep -i spidermonkey
pecl/spidermonkey 0.1.4 JavaScript engine for PHP
が、似たような分割ができるのでは？と思いましたが試していないです。
また
const char * TOKENS[] を修正します。
の詳細は jsscan.h の typedef enum JSTokenType {...} を example.c を参考に修正します。
$ diff /tmp/jsparsenodetree.c jsparsenodetree.c
