In 1990, Karl Berry took over the work, assisted by dozens of additional contributors, and in 1997 he handed the baton to Olaf Weber, who returned it to Karl in 2006. -

Let us first describe the generic path searching mechanism of the Kpathsea library. +

We call a search path a colon- or semicolon-separated list of path elements, which are basically directory names. A search path can come from (a combination of) many sources. To look up a file ‘.:/dir’, Kpathsea checks each element of the pat class="ec-lmtt-10">./my-file, then /dir/my-file, returning the first match (or possibly all matches). -

In order to adapt optimally to all operating systems’ conventions, on non-Unix systems Kpathsea can use filename separators different from colon (‘:’) and slash (‘/’). -

To check a particular path element

To check a particular path element p, Kpathsea first checks if a prebuilt database (see “Filename database” on page 66) applies to p, i.e., if the database is in a directory that is a prefix of p. If so, the path specification is matched against the contents of the database. -

Although the simplest and most common path element is a directory name, Kpathsea supports additional features in search paths: layered default values, environment variable names, config file values, users’ home directories, and recursive subdirectory searching. Thus, we say that Kpathsea expands a path element, meaning it transforms all the specifications into basic directory name or names. This is described in the following sections in the same order as it takes place. -

Note that if the filename being searched for is absolute or explicitly relative, i.e., starts with ‘

Instead, normal installation results in a file

Instead, normal installation results in a file .../2020/texmf.cnf. If you must make changes to the defaults (not normally necessary), this is the place to put them. The main configuration file is in .../2020/texmf-dist/web2c/texmf.cnf. You should not edit this latter file, as your changes will be lost when the distributed version is updated. -

    Exactly when a character will be considered special or act as itself depends on the context in which it is used. The rules are inherent in the multiple levels of interpretation of the configuration (parsing, expansion, search, …) and so cannot be concisely stated, unfortunately. There is no general escape mechanism; in particular, ‘\’ is not an “escape character” in texmf.cnf files. -

    Kpathsea goes to some lengths to minimize disk accesses for searches. Nevertheless, in the standard TEX Live, or at any installation with enough directories, searching every possible directory for a given file will take an excessively long time. Therefore, Kpathsea can use an externally-built plain text “database” file named ls-R that maps files to directories, thus avoiding the need to exhaustively search the disk. -
