*project-root* clj

Project root path, defaults to current directory. Use resolve-path to resolve relative paths in terms of the project-root. Use set-project-root! to override the default for all tasks.

compile-clj clj

(compile-clj params)

Compile Clojure source to classes in :class-dir.

Clojure source files are found in :basis paths by default, else in :src-dirs.

Namespaces and order of compilation are one of:

• :ns-compile - compile these namespaces, in this order
• :sort - find all namespaces in source dirs and use either :topo (default) or :bfs to order them for compilation

Options: :basis - required, basis to use when compiling :class-dir - required, dir to write classes, will be created if needed :src-dirs - coll of Clojure source dirs, used to find all Clojure nses to compile :ns-compile - coll of specific namespace symbols to compile :sort - :topo (default) or :bfs for breadth-first search :compile-opts - map of Clojure compiler options: {:disable-locals-clearing false :elide-meta [:doc :file :line ...] :direct-linking false} :bindings - map of Var to value to be set during compilation, for example: {#'clojure.core/assert false} :filter-nses - coll of symbols representing a namespace prefix to include

Additional options flow to the forked process doing the compile: :java-cmd - Java command, default = $JAVA_CMD or 'java' on $PATH, or $JAVA_HOME/bin/java :java-opts - coll of string jvm opts :use-cp-file - one of: :auto (default) - use only if os=windows && Java >= 9 && command length >= 8k :always - always write classpath to temp file and include :never - never write classpath to temp file (pass on command line)

Returns nil.

copy-dir clj

(copy-dir params)

Copy the contents of the src-dirs to the target-dir, optionally do text replacement. Returns nil.

Globs are wildcard patterns for specifying sets of files in a directory tree, as specified in the glob syntax of java.nio.file.FileSystem: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/file/FileSystem.html#getPathMatcher(java.lang.String)

Options: :target-dir - required, dir to write files, will be created if it doesn't exist :src-dirs - required, coll of dirs to copy from :include - glob of files to include, default = "**" :ignores - collection of ignore regex patterns (applied only to file names), see clojure.tools.build.tasks.copy/default-ignores for defaults :replace - map of source to replacement string in files :non-replaced-exts - coll of extensions to skip when replacing (still copied) default = ["jpg" "jpeg" "png" "gif" "bmp"]

copy-file clj

(copy-file {:keys [src target] :as params})

Copy one file from source to target, creating target dirs if needed. Returns nil.

Options: :src - required, source path :target - required, target path

create-basis clj

(create-basis)

(create-basis params)

Create a basis from a set of deps sources and a set of aliases. By default, use root, user, and project deps and no aliases (essentially the same classpath you get by default from the Clojure CLI).

Each dep source value can be :standard, a string path, a deps edn map, or nil. Sources are merged in the order - :root, :user, :project, :extra.

Options (note, paths resolved via project-root): :root - dep source, default = :standard :user - dep source, default = nil (for reproducibility, not included) :project - dep source, default = :standard ("./deps.edn") :extra - dep source, default = nil :aliases - coll of aliases of argmaps to apply to subprocesses

Returns a runtime basis, which is the initial merged deps edn map plus these keys: :resolve-args - the resolve args passed in, if any :classpath-args - the classpath args passed in, if any :libs - lib map, per resolve-deps :classpath - classpath map per make-classpath-map :classpath-roots - vector of paths in classpath order

delete clj

(delete {:keys [path] :as params})

Delete file or directory recursively, if it exists. Returns nil.

Options: :path - required, path to file or directory

git-count-revs clj

(git-count-revs
  {:keys [dir git-command path] :or {git-command "git"} :as params})

Shells out to git and returns count of commits on this branch: git rev-list HEAD --count

git-process clj

(git-process params)

Run git process in the specified dir using git-command with git-args (which should not start with "git"). git-args may either be a string (split on whitespace) or a vector of strings. By default, stdout is captured, trimmed, and returned.

Options: :dir - dir to invoke this command from, default = current directory :git-command - git command to use, default = "git" :git-args - required, coll of git-arg strings forming a command line OR a string (do not use if args may have embedded spaces) :capture - :out (default) or :err, else nothing

Examples: (api/git-process {:git-args "rev-list HEAD --count"}) (api/git-process {:git-args "branch --show-current"}) (api/git-process {:git-args "rev-parse --short HEAD"}) (api/git-process {:git-args "push", :capture nil})

Note that 'java-command' will NOT resolve any relative paths from basis or cp in terms of project-root, you will get a classpath with the same relative paths. 'process' (if run with this output), will run in the context of the project-root directory.

Options: :java-cmd - Java command, default = $JAVA_CMD or 'java' on $PATH, or $JAVA_HOME/bin/java :cp - coll of string classpath entries, used first (if provided) :basis - runtime basis used for classpath, used last (if provided) :java-opts - coll of string jvm opts :main - required, main class symbol :main-args - coll of main class args :use-cp-file - one of: :auto (default) - use only if os=windows && Java >= 9 && command length >= 8k :always - always write classpath to temp file and include :never - never write classpath to temp file (pass on command line)

Returns map suitable for passing to 'process' with keys: :command-args - coll of command arg strings

javac clj

Options: :src-dirs - required, coll of Java source dirs :class-dir - required, dir to write classes, will be created if needed :basis - classpath basis to use when compiling :javac-opts - coll of string opts, like ["-source" "8" "-target" "8"]

pom-path clj

(pom-path params)

If :class-dir provided, return path will start with resolved class-dir (which may be either absolute or relative), otherwise just relative path in jar.

Options: :lib - required, used to form the relative path in jar to pom.xml :class-dir - optional, if provided will be resolved and form the root of the path

process clj

(process params)

Exec the command made from command-args, redirect out and err as directed, and return {:exit exit-code, :out captured-out, :err captured-err}.

Options: :command-args - required, coll of string args :dir - directory to run the command from, default project-root :out - one of :inherit :capture :write :append :ignore :err - one of :inherit :capture :write :append :ignore :out-file - file path to write if :out is :write or :append :err-file - file path to write if :err is :write or :append :env - map of environment variables to set

The :out and :err input flags take one of the following options: :inherit - inherit the stream and write the subprocess io to this process's stream (default) :capture - capture the stream to a string and return it :write - write to :out-file or :err-file :append - append to :out-file or :err-file :ignore - ignore the stream

resolve-path clj

If path is absolute or root-path is nil then return path, otherwise resolve relative to project-root.

set-project-root! clj

(set-project-root! root)

Set project-root dir (default is ".")

uber clj

(uber params)

Create uberjar file. An uberjar is a self-contained jar file containing both the project contents AND the contents of all dependencies.

The project contents are represented by the class-dir. Use other tasks to put Clojure source, class files, a pom file, or other resources in the class-dir. In particular, see the copy-dir, write-pom, compile-clj, and javac tasks.

The dependencies are pulled from the basis. All transitive deps will be included. Dependency jars are expanded for inclusion in the uberjar. Use :exclude to exclude specific paths from the expanded deps. Use conflict-handlers to handle conflicts that may occur if two dependency jar files include a file at the same path. See below for more detail.

If a main class or manifest are provided, those are put in the uberjar META-INF/MANIFEST.MF file. Providing a main allows the jar to be invoked with java -jar.

Returns nil.

Options: :uber-file - required, uber jar file to create :class-dir - required, local class dir to include :basis - used to pull dep jars :main - main class symbol :manifest - map of manifest attributes, merged last over defaults + :main :exclude - coll of string patterns (regex) to exclude from deps :conflict-handlers - map of string pattern (regex) to built-in handlers, symbols to eval, or function instances

When combining jar files into an uber jar, multiple jars may contain a file at the same path. The conflict handlers are a map of string regex pattern to: a keyword (to use a built-in handler) or a symbol (to resolve and invoke) or a function instance The special key :default specifies the default behavior if not matched.

Conflict handler signature (fn [params]) => effect-map: params: :path - String, path in uber jar, matched by regex :in - InputStream to incoming file (see stream->string if needed) :existing - File, existing File at path :lib - symbol, lib source for incoming conflict :state - map, available for retaining state during uberjar process

Handler should return effect-map with optional keys: :state - updated state map :write - map of string path to map of :string (string) or :stream (InputStream) to write and optional :append flag. Omit if no files to write.

Available built-in conflict handlers: :ignore - don't do anything (default) :overwrite - overwrite (replaces prior file) :append - append the file with a blank line separator :append-dedupe - append the file but dedupe appended sections :data-readers - merge data_readers.clj :warn - print a warning :error - throw an error

Default conflict handlers map: {"^data_readers.clj[c]?$" :data-readers "^META-INF/services/.*" :append "(?i)^(META-INF/)?(COPYRIGHT|NOTICE|LICENSE)(\.(txt|md))?$" :append-dedupe :default :ignore}

unzip clj

(unzip params)

Options: :zip-file - required, zip file to unzip :target-dir - required, directory to unzip in

with-project-root clj macro

(with-project-root path & forms)

Execute forms in a bound project path (string) other than the default (".")

write-file clj

(write-file {:keys [path content string opts] :as params})

Writes a file at path, will create parent dirs if needed. Returns nil. File contents may be specified either with :content (for data, that will be pr-str'ed) or with :string for the string to write. If neither is specified, an empty file is created (like touch).

Options: :path - required, file path :content - val to write, will pr-str :string - string to write :opts - coll of writer opts like :append and :encoding (per clojure.java.io)

write-pom clj

(write-pom params)

Write pom.xml and pom.properties files to the class dir under META-INF/maven/group-id/artifact-id/ (where Maven typically writes these files), or to target (exactly one of :class-dir and :target must be provided). The pom deps, dirs, and repos are either synced from the src-pom or generated from the basis.

If a repos map is provided it supersedes the repos in the basis.

Returns nil.

Options: :basis - required, used to pull deps, repos :src-pom - source pom.xml to synchronize from, default = "./pom.xml" :class-dir - root dir for writing pom files, created if needed :target - file path to write pom if no :class-dir specified :lib - required, project lib symbol :version - required, project version :scm - map of scm properties to write in pom keys: :connection, :developerConnection, :tag, :url See: https://maven.apache.org/pom.html#SCM for details :src-dirs - coll of src dirs :resource-dirs - coll of resource dirs :repos - map of repo name to repo config, replaces repos from deps.edn
