@table @command
+@pindex redo
@item redo
Forcefully and sequentially build specified targets. This is the
main command you will explicitly use from the command line. If no
targets are given, then @file{all} target will be used by default.
+
+@pindex redo-ifchange
@item redo-ifchange
Rebuild specified targets if they are out-of-date and record them as
a dependency for the currently run target. This is the main command
you will use in @file{.do} files.
+
+@pindex redo-ifcreate
@item redo-ifcreate
Record the non-existent file dependency for the currently run
target. Target will be rebuilt if any of the given files appear. Can
the given targets, but ordinary @command{redo} is not: it builds
specified targets sequentially and stops when error happens.
+@cindex tracing
@option{-x} option can be used to enable tracing (@code{set -x}) of the
currently run shell script @file{.do} file. @option{-xx} option enables
tracing for all invoked @file{.do} files further.
+@cindex parallel build
With @option{-j} option you can enable parallel builds, probably with an
infinite number of workers (@code{=0}). Also you can set
@env{$REDO_JOBS} to automatically apply that setting globally.
Read about @ref{Logs, log storage capabilities}.
+@cindex debug
+@vindex REDO_LOG_PID
+@vindex REDO_DEBUG
@option{-log-pid} (@env{$REDO_LOG_PID=1}) can be used to prefix job's
@code{stderr} with the PID, that could be useful during parallel builds.
@option{-d} (@env{$REDO_DEBUG=1}) enables debug messages.
+@cindex progress
+@vindex REDO_NO_PROGRESS
+@vindex REDO_NO_STATUS
+@vindex NO_COLOR
@option{-no-progress} (@env{$REDO_NO_PROGRESS=1}) and
@option{-no-status} (@env{$REDO_NO_STATUS=1}) disable statusline and
progress display. @env{$NO_COLOR=1} disables progress/debug messages
colouring.
+@cindex fsync
+@vindex REDO_NO_SYNC
By default all build commands use @code{fsync} to assure data is reached
the disk. You can disable its usage with @env{$REDO_NO_SYNC=1}
environment variable, for speeding up the build process.
+@vindex REDO_STOP_IF_MODIFIED
+If redo sees some target modified externally, then by default it warns
+user about that, does not build that target, but continues the build
+process further. That is convenient in most cases: you can build your
+project with manual targets alterings, without touching possibly more
+complicated @file{.do} files. With @env{$REDO_STOP_IF_MODIFIED=1} redo
+won't continue and will exit with failure message.

There are other commands that could be found in other implementations too:
@table @command
+@pindex redo-always
@item redo-always
Record current target as an always-do dependency. By definition it
should be always build. @command{goredo} tries to build it once per
@strong{run}.
+
+@pindex redo-stamp
@item redo-stamp
Record "stamp" dependency. It reads @code{stdin} and stores its hash
in the dependency database. It is not used anyhow, it is dummy. Read
about @ref{Stamping, stamping} in the FAQ. It is left only for
compatibility with some other implementations.
+
+@pindex redo-targets
+@pindex redo-ood
@item redo-targets, redo-ood
Show all known targets, possibly limited by specified directories.
@command{redo-ood} shows only the out-of-date ones.
+
+@pindex redo-sources
@item redo-sources
Recursively show all source files the given targets depend on.
+
+@pindex redo-affects
@item redo-affects
It is not in other distributions, but it is some kind of opposite of
@command{redo-sources} -- shows the targets that will be affected by
And there are some maintenance and debug commands:
@table @command
+@pindex redo-cleanup
@item redo-cleanup
Removes either temporary (@option{tmp}), log files (@option{log}),
- or everything related to @command{goredo} (@option{full}).
+ lock files (@option{lock}), or everything related to @command{goredo}
+ (@option{full}).
+@pindex redo-whichdo
@item redo-whichdo
Display @file{.do} search paths for specified target (similar to
@command{apenwarr/redo}):
../default.do
@end example
+@pindex redo-dot
@item redo-dot
Dependency
@url{https://en.wikipedia.org/wiki/DOT_(graph_description_language), DOT}
$ dot -Tpng whatever.dot > whatever.png # possibly add -Gsplines=ortho
@end example
+@pindex redo-depfix
@item redo-depfix
When you copy your worktree to different place, then copied files
ctime will change. And because recorded dependency information
