debugging - How to debug into subprocess.call() in Python? -


i trying understand project's source code these days. run project, line line, works fine until line:

res = subprocess.call(command, env=os.environ)

i checked variable "command" , realized function throw command python script , try execute in subprocess. jumped out of eclipse, , tried execute command through terminal while under same directory.

now got:

traceback (most recent call last):   file "/home/elderry/projects/git/tahoe-lafs/support/bin/tahoe", line 6, in <module>     pkg_resources import load_entry_point   file "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2850, in <module>     working_set.require(__requires__)   file "/usr/lib/python2.7/site-packages/pkg_resources.py", line 696, in require     needed = self.resolve(parse_requirements(requirements))   file "/usr/lib/python2.7/site-packages/pkg_resources.py", line 594, in resolve     raise distributionnotfound(req) pkg_resources.distributionnotfound: allmydata-tahoe==1.10.0.post27

then lost direction, did subprocess continue run? why did script work in program not in terminal? since script included in project, hope set break points in in eclipse, didn't catch anything. there way debug subprocess, not dive code of subprocess module's code itself?

i guess main project alters pythonpah (sys.path). in os.environ of project , try run second script environment.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
