\ paths.fs path file handling 03may97jaw |
|
|
|
\ -Changing the search-path: |
|
\ fpath+ <path> adds a directory to the searchpath |
|
\ fpath= <path>|<path> makes complete now searchpath |
|
\ seperator is | |
|
\ .fpath displays the search path |
|
\ remark I: |
|
\ a ./ in the beginning of filename is expanded to the directory the |
|
\ current file comes from. ./ can also be included in the search-path! |
|
\ ~+/ loads from the current working directory |
|
|
|
\ remark II: |
|
\ if there is no sufficient space for the search path increase it! |
|
|
|
|
|
\ -Creating custom paths: |
|
|
|
\ It is possible to use the search mechanism on yourself. |
|
|
|
\ Make a buffer for the path: |
|
\ create mypath 100 chars , \ maximum length (is checked) |
|
\ 0 , \ real len |
|
\ 100 chars allot \ space for path |
|
\ use the same functions as above with: |
|
\ mypath path+ |
|
\ mypath path= |
|
\ mypath .path |
|
|
|
\ do a open with the search path: |
|
\ open-path-file ( adr len path -- fd adr len ior ) |
|
\ the file is opened read-only; if the file is not found an error is generated |
