I want to know how to extrapolate the vim variables, for example, to format the file I am working on.
:!fmt -w mifichero
when working in several directories referencing the path of the file It's tedious.
:!fmt -w /home/user/miproyect/lalaala/otro_directorio/otro_mas/mi_fichero
the idea would be to extrapolate some vim variable in the command mode.
Does anyone know?
On the command line you can use the wildcard %:p to get the full path of the file you are editing. Obviously it will not work with a buffer that you have not yet saved the file, and of course, the command will only act with the last changes that you have saved. For example:
:!fmt -w 80 %:p
If you want to redirect the output to the same buffer, you can do
:r !fmt -w 80 %:p # En la posicion actual
:0r !fmt -w 80 %:p # Al comienzo del buffer
Or if you want to replace the entire content:
:% !fmt -w 80 %:p
