Modern Fortran port of Python's shlex shell-like lexer. This package implements the simple shlex lexer, inspired by the Python shlex module, and based on the Golang implementation. The interface comes with two functions, split which parses a command-like string and returns an array of allocatable character strings; and shlex that perform the same, but return a list of type(shlex_token) tokens. Error control is optional, via a boolean success keyword or a token that may return an error string.
Just copy and paste shlex_module.f90 into your project. Alternatively, fortran-shlex can be used as a dependency in your Fortran Package Manager project:
[dependencies]
fortran-shlex = { git="https://github.com/perazz/fortran-shlex.git" }
The split function returns a list of strings, split according to unix shell rules, which support:
- escaping quotes (
"...") - non-escaping quotes (
'...') - line feed, carriage return etc.
use shlex_module
character(len=:), allocatable :: tokens(:)
type(shlex_token) :: error
logical :: success
! Simple usage
tokens = split('my -W"ery" -Llong //Input \n "string"')
! With logical error flag
tokens = split('whatever ',success=success)
! With complete error flag
tokens = split('whatever ',error)
print *, 'error message=',error%string
And the shlex function has the same API, but returns a list of type(shlex_token)s instead of an allocatable character array.
use shlex_module
type(shlex_token), allocatable :: tokens(:)
type(shlex_token) :: error
logical :: success
! Simple usage
tokens = shlex('my -W"ery" -Llong //Input \n "string"')
! With logical error flag
tokens = shlex('whatever ',success=success)
! With complete error flag
tokens = shlex('whatever ',error)
print *, 'error message=',error%string
