# Slide Script, also refered to as SS, is extremely forgiving in
# syntax handling!
# Example:
#    print "content"
#    print "content";
#    print("content")
#    print("content");
###
### These will operate properly, as well as:
# Example:
#    write "filename.txt" "data"
#    write "filename.txt" "data";
#    write("filename.txt" "data");
#    write("filename.txt", "data");
#
#   IT ALL WORKS! 
# SlideScript really syntaxes based on quotes and key function words, 
# as well as pipes. It really doesn't mind whats around it otherwise
# And every variable is called by %varname%, defining variables, as normal

# Variables in SS
ss_filename=file.txt
ss_stringdata=Data to encrypt and decrypt
ss_exec_command=uname -a

# Printing function in SS
print "Welcome to SlideScript!"
# Sleep function in SS
print "Some content to print, working with '%ss_filename%' today!"
# Below demonstrates SS encrypting a string, passing the output
# over a pipe, and using the write function and %PIPE% variable
# holding the first functions output, writes to %ss_filename%; file.txt
### %PIPE% is the output from the first line function, enc
### %PIPE% is always applied when a pipe is used!
encode "%ss_stringdata%" | write "%ss_filename%" "%PIPE%" 
# You're left with file.txt, lets move on

# Lets read the file we just created and show how SS handles its
# own decryption algorithm
read "%ss_filename%" | decrypt "%PIPE%"
# Will display the original variable string!

# SS MD5 function
# Lets get the md5sum of file.txt with our md5 function
md5 "%ss_filename%" | write "%ss_filename%.md5" "%PIPE%"
# Use a pipe, and push the md5 into a text file of file.txt

# You can also stack pipes for whatever tasks you may need
# Here's the encrypt function in action, can also be used as encode
md5 "%ss_filename%" | encode "%PIPE%" | write "%ss_filename%.md5.enc" "%PIPE%"

# Read md5 file
print "%ss_filename%.md5:"
read "%ss_filename%.md5"

# Read encrypted md5 file and decrypt using decode alias
print "%ss_filename%.md5.enc:"
read "%ss_filename%.md5.enc" | decode "%PIPE%"

# Delete function, SS can delete files and directories with one function
# NOTE: it is extremely powerful and can wreck your system if used in the
# wrong way! Proceed with caution, delete "/" WILL send your files to the
# grave.
###
# Lets delete the files we've been messing with, no system calls needed
delete "%ss_filename%"
delete "%ss_filename%.md5"
delete "%ss_filename%.md5.enc"
# Gone!

print "Playing with some calc..."
# calc function, lets do some basic math
calc "32 * 1024"
# You can pipe calc to do multi layer equations
calc "32 * 1024" | calc "%PIPE% * 2"

# Lets play with some big numbers here!
# SlideScript parses its calc functions using floating points, so you can 
# handle decimal as well
calc "1024 * 1024" | calc "%PIPE% * %PIPE%"

# Decimal
print "Here comes the decimal:"
calc "46 / 3.4"

# Execute function, SS can call unix system calls!
# Executes the ss_exec_command variable data, 'ls'
print "Testing exec function on system"
exec "%ss_exec_command%"
