str >> cmd is feed ~string:str cmd.

a ||> b is a shortcut for pipe [a; b].

Call a command from its list of “arguments” (including the first argument being the actual command).

Create a normal case for a EDSL.switch statement.

Create the default case for a EDSL.switch statement.

Like EDSL.printf but redirected to "stderr".

Like EDSL.call but with string literals; i.e.

Expression that aborts the whole script/command immediately.

Feed some content (~string) into the "stdin" filedescriptor of a unit t expression.

Get the value of an environment variable as a string; it returns the empty string when the variable is not defined.

if_seq c ~t ~e is an alternate API for EDSL.if_then_else (when ?e is provided) or EDSL.if_then (otherwise) that assumes “then” and “else” bodies to be lists for EDSL.seq construct.

The silent “no-operation.”

Pipe commands together ("stdout" into "stdin" exactly like the " | " operator).

printf fmt l is call (string "printf" :: string "--" :: fmt :: l).

Check the return value of a command/expression/script.

Sequence a list of expressions into an expression.

Set the value of an environment variable as a string; it returns the empty string is the variable is not defined.

Concatenate an (OCaml) list of string t values.

Concatenate a Genspio list of strings string list t.

succeeds expr is a equivalent to returns expr ~value:0.

Create a switch statement from a list of EDSL.case and optionally a EDSL.default (the function raises an exception if there are more than one default cases).

Create a temporary file that may contain arbitrary strings (can be used as variable containing string t values).

Create a file-descriptor to file-descriptor redirection.

Create a file-descriptor to file redirection.

Compile a Genspio expression to a multi-line POSIX shell script, slightly more readable than Compile.to_one_liner.

Compile a Genspio expression to a single-line POSIX shell command.

Put any string as a unit t command inline (Magic.unit s is different from exec ["sh"; "-c"; s] there is no escaping or protection).

with_failwith f uses ! and EDSL.with_signal to call f with a function that exits the flow of execution and displays ~message and returns ~return (a bit like Pervasives.failwith).

Run a unit t expression after applying a list of file-descriptor redirections.

Use a UNIX signal (default "USR2") to create a “jump.”

Redirect selected streams or the return value to files (stdout, stderr, return_value are paths).

write_stdout ~path expr is write_output expr ~stdout:path.
