In this paper, we propose a virtual file system, "SPDFS,"
which provides global declarations in source programs as
virtual files to programmers. Global declarations means
objects which declare identifiers in external scope, such as
function definition and variable declaration. On SPDFS,
programmers can edit virtual files directly by their favorite
editors. Changes to declarations in a virtual file are to be
applied to real source files automatically. SPDFS can also
provide a set of relevant declarations distributed in different
source files as a virtual file. Relevancy of declarations
in this paper means references among declarations. SPDFS
retrieves declarations which are referred by or refer to the
target declaration and combine them in a virtual file. The
depth of references can be specified in a file path by programmers.
SPDFS reduces the amount of source programs
which programmers need to read for editing and the amount
of programmers’ works for searching relevant declarations.
We show an implementation of SPDFS using the portal file
system on FreeBSD. The portal file system invokes commands
for reading and writing a virtual file respectively.
These commands work as user-land process. Because no
modification of kernel is required, it is easy to customize
the behavior of SPDFS. We also show the effectiveness of
SPDFS by comparing numbers of lines of source programs
which programmers need to read for editing.
