README
Query-FS is a virtual filesystem implemented using FUSE in Common Lisp. Its current main usecase is providing a POSIX FS API to access and modify some data in SQL databases. One can write: mkdir "all" do for x in "select name, content from test_table" with-file $name do on-read $x[1] on-write data "update test_table set content = ${data} where name = ${name}" on-remove "delete from test_table where name = ${name}" done on-create-file name "insert into test_table (name) values (${name})" done and browse and modify a DB table as a directory. One can also write some queries in Common Lisp: (mk-pair-generator x (let ((xn (ignore-errors (parse-integer (first x))))) (if xn `((,(first x) ,(1+ xn))) (loop for k from 1 to 10 collect `(,(format nil "~a" k) ,(1+ k))))) (mk-file (first x) (format nil "~a" (second x)))) Installation and use: $ cd ~/quicklisp/local-projects $ git clone https://gitlab.common-lisp.net/cl-fuse/query-fs $ mkdir -p query-fs-test/queries $ $EDITOR query-fs-test/queries/… * (ql:quickload :query-fs) * (query-fs:run-fs :target "query-fs-test") See example queries in example-queries and clsql-queries
