LP Source:

 ```bash lp asserts=Hello fmt=xt_flat session=foo
 echo "Hello World"
 ```

Result:

$ echo "Hello World"
Hello World

LP Source:

 ```bash lp asserts=Hello fmt=xt_flat
 ls -lta /usr/bin | grep env # lp: asserts=env
 echo "Hello World"          # lp: asserts="[World and Hello] or Foo" 
 ```

Defining a function for later use:

LP Source:

 ```bash lp new_session=test
 say_hello () { 
     echo -e "Hello, from \n"$(env | grep -i tmux)""; 
 }
 ```

Result:

CmdOutput

$ say_hello () { 
    echo -e "Hello, from \n"$(env | grep -i tmux)""; 
}

$ say_hello () { 
>     echo -e "Hello, from \n"$(env | grep -i tmux)""; 
> }
$

Heredocs

the example includes the previously defined function:

LP Source:

 ```bash lp session=test asserts=TMUX
 echo $0 # lp: expect=bash
 export -f say_hello
 /bin/bash # lp: expect=
 echo $0 # lp: expect=bash
 say_hello
 R="\x1b["; r="${R}1;31m"
 echo -e "Means: We do have
 > - $r Cross block sessions  ${R}0m
 > - $r Blocking commands/subshells     ${R}0m
 > - and...${R}4m$r Full Ansi
 > "
 ```

Result:

CmdOutput

$ echo $0
$ export -f say_hello
$ /bin/bash
$ echo $0
$ say_hello
$ R="\x1b["; r="${R}1;31m"
$ echo -e "Means: We do have
- $r Cross block sessions  ${R}0m
- $r Blocking commands/subshells     ${R}0m
- and...${R}4m$r Full Ansi
"

$ echo $0
-bash

$ export -f say_hello

Means: We do have
-  Cross block sessions  
-  Blocking commands/subshells     
- and... Full Ansi
