java - Some clarifications about how ant copy some files into a folder? -


this question exact duplicate of:

i pretty new ant (i came maven , ant nightmare me !!!)

i have target:

<target name="linuxdriver"     description="linux driver">     <copy file="${deps.linuxdriver.dir}/${deps.linuxdriver.name}"           tofile="${project.datadir}/${deps.linuxdriver.name}"/>     <copy file="${deps.linuxdriver.dir}/${deps.linuxdriver.name}"           tofile="${project.deploy}/data/${deps.linuxdriver.name}"/>     <chmod perm="+x" file="${project.datadir}/${deps.linuxdriver.name}"/>     <chmod perm="+x" file="${project.deploy}/data/${deps.linuxdriver.name}"/> </target>

and have property file in there definied "variable" (are named variable?) used in previous ant code, have:

project.datadir = ${basedir}/data  project.deploy.dir = release  project.deploy = ${basedir}/../${project.deploy.dir}  deps.linuxdriver.name = atmosfs

and have doubts:

1) represents ${basedir}? specific directory? what? reading on ant manual (http://ant.apache.org/manual/properties.html) is: the absolute path of project's basedir (as set basedir attribute of ).

so, absolute path of project in eclipse workspace?

2) using previous information 2 destination folder in files copied (using "copy file...to file" tag)?

1) represents ${basedir}? specific directory?

yes. ${basedir} directory either started ant, or directory specified in <project> entity on top of ant file. normally, set "." makes same directory directory contains ant build file.

2) using previous information 2 destination folder in files copied (using "copy file...to file" tag)?

you didn't list whole ant file, , whole properties file. i'm not sure if properties file read in (you need <property file="xxxx.properties"/> near top of ant file).

assuming executing in same directory ant file, , ${basedir} same directory ant file:

<copy file="${basedir}/atmosfs/atmostfs"     verbose="true"     tofile="${basedir}/release/atmosfs"/> <copy file="${basedir}/atmofs/atmofs"     verbose="true"     tofile="${basedir}/../release/data/atmofs"/>

again, assuming ${basedir} directory antfile stored, , executing script directory.

notice have verbose="true" in <copy>. recommend make change. show file being copied , when <copy> executed. it's best way handle this.

by way, 1 rule have action takes place in project tree. last tofile being written outside of project directory (where assume ant file located). imagine checking out project, , finding out build process wrote file outside of checked out directory , onto computer in random place. doing considered impolite.

even more polite write files , build processing under subdirectory. people use build, prefer target because that's maven standard. idea can clean entire build process deleting 1 directory.

i'm working on adding multiple querystring , doesn't seem work. i've found codes seems work others might i'm missing something. i want like: http://mydomain.com/board/?getyear=2013&getsometext2=sometext to http://mydomain.com/board/2013/sometext/ i added code below functions.php file. doesn't seem work should though. this works. echoing querystring gets both variable without problem. http://mydomain.com/board/2013/sometext/ but doesn't. tested querystring vis isset() seems nothing being set/get http://mydomain.com/board/2013/ function add_query_vars($vars) { $vars[] = "getyear"; $vars[] = "getsometext2"; return $vars; } add_filter('query_vars', 'add_query_vars'); function add_rewrite_rules($arules) { $anewrules = array('board/([^/]+)/([^/]+)/?$' => 'index.php?pagename=board&getyear=$matches[1]&getsometext2=$matches[2]'); $arules = $a

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
