;+ ;PROCEDURE: rbsp_emfisis_init ;PURPOSE: Initializes system variables for RBSP EMFISIS. Can be called from idl_startup to set ; custom locations. ; ; The system variable !RBSP_EMFISIS is defined here. The elements of this structure are explained below: ; ; !RBSP_EMFISIS.LOCAL_DATA_DIR This is the root location for all RBSP EMFISIS data files. ; The RBSP EMFISIS software expects all data files to reside in specific subdirectories relative ; to this root directory.; ; ; !RBSP_EMFISIS.REMOTE_DATA_DIR This is the URL of the server that can provide the data files. ; (default is: "http://themis.ssl.berkeley.edu/data/themis/") ; if the software does not find a needed file in LOCAL_DATA_DIR, ; then it will attempt to download the data from the URL and REMOTE_DATA_DIR is defined, ; the software will attempt to download the file from REMOTE_DATA_DIR, place it in LOCAL_DATA_DIR ; with the same relative pathname, and then continue processing. ; (NOT YET IMPLEMENTED) ; ; ;KEYWORDS: ; RESET: Reset !rbsp to values in environment (or values in keywords). ; LOCAL_DATA_DIR: use given value for local_data_dir, rather than environment. Only works on ; initial call or reset. ; REMOTE_DATA_DIR: Use given value for remote_data_dir, rather than env. Only works on inital ; call or reset. ; NO_COLOR_SETUP do not set colors if already taken care of ; ; Typical examples: ; ; Desktop UNIX/LINUX computer located at SSL ; LOCAL_DATA_DIR = '/disks/data/rbsp/' ; This master directory is read only. ; REMOTE_DATA_DIR = '' ; Should be empty string. (/disks/data/rbsp and server are the same) ; ; Desktop WINDOWS computer located at SSL ; LOCAL_DATA_DIR = '\\justice\data\rbsp\' ; Justice is a samba server (physically the same as /disk/data/rbsp) ; REMOTE_DATA_DIR = '' ; ; laptop WINDOWS computer located far from a data server, but with internet connection. ; LOCAL_DATA_DIR = 'C;\data\rbsp\' ; Local (portable) directory on laptop ; REMOTE_DATA_DIR = 'http://themis.ssl.berkeley.edu/data/themis/' ; URL used to download data to LOCAL_DATA_DIR ; ; MacOS computer located away from SSL without a nearby data server ; LOCAL_DATA_DIR = '/data/rbsp/' ; Local (portable) directory on laptop ; REMOTE_DATA_DIR = 'http://themis.ssl.berkeley.edu/data/themis/' ; URL used to download data to LOCAL_DATA_DIR ; ; Note: If automatic downloads are used. (i.e. REMOTE_DATA_DIR is not an empty string) the user must ensure that ; LOCAL_DATA_DIR is writeable. ; ; Note to WINDOWS users: the WINDOWS version of IDL accepts both the '\' and '/' character as the directory ; separation character. The converse is not true. ; ; ;HISTORY ; Written by Peter Schroeder July 2011 ; ;$LastChangedBy: peters $ ;$LastChangedDate: 2014-02-06 15:30:23 -0800 (Thu, 06 Feb 2014) $ ;$LastChangedRevision: 14188 $ ;$URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/general/missions/rbsp/emfisis/rbsp_emfisis_init.pro $ ;- pro rbsp_emfisis_init, reset=reset, local_data_dir=local_data_dir, remote_data_dir=remote_data_dir, $ no_color_setup=no_color_setup,no_download=no_download cdf_leap_second_init defsysv,'!rbsp_emfisis',exists=exists if not keyword_set(exists) then begin defsysv,'!rbsp_emfisis', file_retrieve(/structure_format) endif if keyword_set(reset) then !rbsp_emfisis.init=0 if !rbsp_emfisis.init ne 0 then return !rbsp_emfisis = file_retrieve(/structure_format) ; force setting of all elements to default values. rbsp_emfisis_config,no_color_setup=no_color_setup,no_download=no_download ; keywords on first call rbsp_emfisis_init (or /reset) override environment and ; rbsp_emfisis_config if keyword_set(local_data_dir) then begin temp_string = strtrim(local_data_dir, 2) ll = strmid(temp_string, strlen(temp_string)-1, 1) If(ll Ne '/' And ll Ne '\') Then temp_string = temp_string+'/' !rbsp_emfisis.local_data_dir = temporary(temp_string) endif if keyword_set(remote_data_dir) then begin temp_string = strtrim(remote_data_dir, 2) ll = strmid(temp_string, strlen(temp_string)-1, 1) If(ll Ne '/' And ll Ne '\') Then temp_string = temp_string+'/' !rbsp_emfisis.remote_data_dir = temporary(temp_string) endif servertestfile = '.rbsp_emfisis_master' ; This file should only be found on the server.
