Without the branch being specified, the fetcher\n > might fail if the default branch changes. Additionally, it can\n > be confusing to try a commit from a non-default branch and see\n > the fetch fail. If the branch is specified the fault is much\n > more obvious.\n\n - If the revision you're looking for is in the default branch of\n the git repository you may omit the `ref` attribute.\n\n ```nix\n builtins.fetchGit {\n url = \"https://github.com/nixos/nix.git\";\n rev = \"841fcbd04755c7a2865c51c1e2d3b045976b7452\";\n }\n ```\n\n - To fetch a specific tag:\n\n ```nix\n builtins.fetchGit {\n url = \"https://github.com/nixos/nix.git\";\n ref = \"refs/tags/1.9\";\n }\n ```\n\n - To fetch the latest version of a remote branch:\n\n ```nix\n builtins.fetchGit {\n url = \"ssh://git@github.com/nixos/nix.git\";\n ref = \"master\";\n }\n ```\n\n > **Note**\n >\n > Nix will refetch the branch in accordance with\n > the option `tarball-ttl`.\n\n > **Note**\n >\n > This behavior is disabled in *Pure evaluation mode*."

The top-level path component of the\nfiles in the tarball is removed, so it is best if the tarball\ncontains a single directory at top level. The typical use of the\nfunction is to obtain external Nix expression dependencies, such as\na particular version of Nixpkgs, e.g.\n\n```nix\nwith import (fetchTarball https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz) {};\n\nstdenv.mkDerivation { … }\n```\n\nThe fetched tarball is cached for a certain amount of time (1\nhour by default) in `~/.cache/nix/tarballs/`.

Since `<hash>` depends on the\n> unfiltered directory, the name of the output directory will\n> indirectly depend on files that are filtered out by the\n> function. This will trigger a rebuild even when a filtered out\n> file is changed. Use `builtins.path` instead, which allows\n> specifying the name of the output directory.\n\nThis function allows you to copy sources into the Nix store while\nfiltering certain files. For instance, suppose that you want to use\nthe directory `source-dir` as an input to a Nix expression, e.g.\n\n```nix\nstdenv.mkDerivation {\n ...\n src = ./source-dir;\n}\n```\n\nHowever, if `source-dir` is a Subversion working copy, then all\nthose annoying `.svn` subdirectories will also be copied to the\nstore. Worse, the contents of those directories may change a lot,\ncausing lots of spurious rebuilds. With `filterSource` you can\nfilter out the `.svn` directories:\n\n```nix\nsrc = builtins.filterSource\n (path: type: type != \"directory\" || baseNameOf path != \".svn\")\n ./source-dir;\n```\n\nThus, the first argument *e1* must be a predicate function that is\ncalled for each regular file, directory or symlink in the source\ntree *e2*. If the function returns `true`, the file is copied to the\nNix store, otherwise it is omitted. The function is called with two\narguments. The first is the full path of the file. The second is a\nstring that identifies the type of the file, which is either\n`\"regular\"`, `\"directory\"`, `\"symlink\"` or `\"unknown\"` (for other\nkinds of files such as device nodes or fifos — but note that those\ncannot be copied to the Nix store, so if the predicate returns\n`true` for them, the copy will fail). If you exclude a directory,\nthe entire corresponding subtree of *e2* will be excluded."

"doc": "Store the string *s* in a file in the Nix store and return its\npath. The file has suffix *name*. This file can be used as an\ninput to derivations. One application is to write builders\n“inline”. For instance, the following Nix expression combines the\n[Nix expression for GNU Hello](expression-syntax.md) and its\n[build script](build-script.md) into one file:\n\n```nix\n{ stdenv, fetchurl, perl }:\n\nstdenv.mkDerivation {\n name = \"hello-2.1.1\";\n\n builder = builtins.toFile \"builder.sh\" \"\n source $stdenv/setup\n\n PATH=$perl/bin:$PATH\n\n tar xvfz $src\n cd hello-*\n ./configure --prefix=$out\n make\n make install\n \";\n\n src = fetchurl {\n url = \"http://ftp.nluug.nl/pub/gnu/hello/hello-2.1.1.tar.gz\";\n sha256 = \"1md7jsfd8pa45z73bz1kszpp01yw6x5ljkjk2hx7wl800any6465\";\n };\n inherit perl;\n}\n```\n\nIt is even possible for one file to refer to another, e.g.,\n\n```nix\nbuilder = let\n configFile = builtins.toFile \"foo.conf\" \"\n # This is some dummy configuration file.\n ...\n \";\nin builtins.toFile \"builder.sh\" \"\n source $stdenv/setup\n ...\n cp ${configFile} $out/etc/foo.conf\n\";\n```\n\nNote that `${configFile}` is an\n[antiquotation](language-values.md), so the result of the\nexpression `configFile`\n(i.e., a path like `/nix/store/m7p7jfny445k...-foo.conf`) will be\nspliced into the resulting string.\n\nIt is however *not* allowed to have files mutually referring to each\nother, like so:\n\n```nix\nlet\n foo = builtins.toFile \"foo\" \"...${bar}...\";\n bar = builtins.toFile \"bar\" \"...${foo}...\";\nin foo\n```\n\nThis is not allowed because it would cause a cyclic dependency in\nthe computation of the cryptographic hashes for `foo` and `bar`.\n\nIt is also not possible to reference the result of a derivation. If\nyou are using Nixpkgs, the `writeTextFile` function is able to do\nthat."

The main\napplication for `toXML` is to communicate information with the\nbuilder in a more structured format than plain environment\nvariables.\n\nHere is an example where this is the case:\n\n```nix\n{ stdenv, fetchurl, libxslt, jira, uberwiki }:\n\nstdenv.mkDerivation (rec {\n name = \"web-server\";\n\n buildInputs = [ libxslt ];\n\n builder = builtins.toFile \"builder.sh\" \"\n source $stdenv/setup\n mkdir $out\n echo \"$servlets\" | xsltproc ${stylesheet} - > $out/server-conf.xml ①\n \";\n\n stylesheet = builtins.toFile \"stylesheet.xsl\" ②\n \"<?xml version='1.0' encoding='UTF-8'?>\n <xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0'>\n <xsl:template match='/'>\n <Configure>\n <xsl:for-each select='/expr/list/attrs'>\n <Call name='addWebApplication'>\n <Arg><xsl:value-of select=\\\"attr[@name = 'path']/string/@value\\\" /></Arg>\n <Arg><xsl:value-of select=\\\"attr[@name = 'war']/path/@value\\\" /></Arg>\n </Call>\n </xsl:for-each>\n </Configure>\n </xsl:template>\n </xsl:stylesheet>\n \";\n\n servlets = builtins.toXML [ ③\n { path = \"/bugtracker\"; war = jira + \"/lib/atlassian-jira.war\"; }\n { path = \"/wiki\"; war = uberwiki + \"/uberwiki.war\"; }\n ];\n})\n```\n\nThe builder is supposed to generate the configuration file for a\n[Jetty servlet container](http://jetty.mortbay.org/). A servlet\ncontainer contains a number of servlets (`*.war` files) each\nexported under a specific URI prefix. So the servlet configuration\nis a list of sets containing the `path` and `war` of the servlet\n(①). This kind of information is difficult to communicate with the\nnormal method of passing information through an environment\nvariable, which just concatenates everything together into a\nstring (which might just work in this case, but wouldn’t work if\nfields are optional or contain lists themselves). Instead the Nix\nexpression is converted to an XML representation with `toXML`,\nwhich is unambiguous and can easily be processed with the\nappropriate tools. For instance, in the example an XSLT stylesheet\n(at point ②) is applied to it (at point ①) to generate the XML\nconfiguration file for the Jetty server. The XML representation\nproduced at point ③ by `toXML` is as follows:\n\n```xml\n<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <list>\n <attrs>\n <attr name=\"path\">\n <string value=\"/bugtracker\" />\n </attr>\n <attr name=\"war\">\n <path value=\"/nix/store/d1jh9pasa7k2...-jira/lib/atlassian-jira.war\" />\n </attr>\n </attrs>\n <attrs>\n <attr name=\"path\">\n <string value=\"/wiki\" />\n </attr>\n <attr name=\"war\">\n <path value=\"/nix/store/y6423b1yi4sx...-uberwiki/uberwiki.war\" />\n </attr>\n </attrs>\n </list>\n</expr>\n```\n\nNote that we used the `toFile` built-in to write the builder and\nthe stylesheet “inline” in the Nix expression. The path of the\nstylesheet is spliced into the builder using the syntax `xsltproc\n${stylesheet}`."
