fix: lib/runscripts/util.run: $wrap_fn: make it usable even if $top_script isn't world-executable

fix: lib/runscripts/util.run: to_top_file(): handle $_remake properly, without requiring deferred_check_target_exists to set to_file()'s flags

*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

lib/sh/make.sh: self_make(): renamed to with_rm() for clarity, since this is used only to progagate $rm, and does not also invoke a command with the same name as the current function, as the name might suggest

lib/runscripts/util.run: support conventional main() method as well as `all` target

lib/runscripts/util.run: on_exit(): documented that users can also override gateway()/fallback() to perform other commands (or no commands) after the script is read

fix: lib/runscripts/util.run: run_args_cmd(): need to indent the output of the target that it's running

lib/sh/util.sh: clog*: renamed to log* for clarity (possible now that log* is no longer used for function-local log_level setting)

lib/runscripts/util.run: runscript template: added sample make target, using new make target template

bugfix: lib/runscripts/util.run: $auto_ignore: need to unexport it so don't pass this to invoked scripts except through fwd()

bugfix: lib/runscripts/util.run: auto_fwd's fallback() must be set after auto_ignore's fallback() to overwrite it (auto_ignore should only apply if an error would otherwise have been generated by the fallback)

lib/runscripts/util.run: fwd(): support subdirs that don't contain a runscript, so that the default value of @subdirs will work in most cases

lib/runscripts/util.run: fwd(): set default @subdirs (`{.,}*/`)

lib/runscripts/util.run: fwd(): enable $auto_ignore so that each subdir doesn't have to have a definition for the forwarded target

lib/runscripts/util.run: added $auto_ignore switch, which causes fallback() not to generate an error that a non-existant target doesn't exist

lib/runscripts/util.run: added fwd_self alias

lib/runscripts/util.run: added $auto_fwd switch

bugfix: lib/runscripts/util.run: gateway(): need to use is_callable() rather than func_exists() to check whether the target exists, because external commands (eg. echo) are supported as targets, too

lib/runscripts/util.run: support custom handlers for all targets (gateway()) as well as targets w/o function (fallback())

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: lib/runscripts/util.run: `trap on_exit EXIT`: only set this if the script is not a dot script, because if it is a dot script, on_exit() will not be invoked until the calling shell exits, which may be much later than when the script is run. previously, this was handled by canceling the EXIT trap if on_exit() is run manually, but this would not work correctly if a load-time error prevented on_exit() from running and canceling the trap.

bugfix: lib/runscripts/util.run: if is_dot_script, fix $ when no args causes this to incorrectly contain the script name. use is_dot_script rather than the presence of $ args to decide whether to use @BASH_ARGV, because @BASH_ARGV is actually wrong when run as a .-script (it contains the script name).

lib/runscripts/util.run: run script template: changed sample command name to all() because each runscript requires this in order to be run without args

lib/runscripts/util.run: support scripts that are run as shell-includes (with leading "."), by allowing the calling script to manually invoke on_exit() without it then being invoked twice (the end of a shell-include does not trigger the EXIT trap)

lib/runscripts/util.run: support scripts that are run as shell-includes (with leading "."), by also accepting $@ args that are passed along in the util.run include, in addition to @BASH_ARGV

bugfix: lib/runscripts/util.run: to_top_file(): need to pass "$@" to to_file

lib/runscripts/util.run: to_top_file: added function for this (in addition to alias), so that this can be run from sudo in a wrap_fn command

lib/runscripts/util.run: added $wrap_fn to run any function via sudo, etc.

lib/runscripts/util.run: usage: documented that this usage also applies to all files that include this file

lib/runscripts/util.run: usage: clarified that the cmd to run is a function

lib/runscripts/util.run: added to_top_file alias for use with $top_file

lib/runscripts/util.run: added , function, which treats each of the command-line args as commands the way make does (instead of as args to the same command, the way runscripts do)

lib/sh/util.sh: moved runscript-related commands to lib/runscripts/util.run because these only apply to runscripts

*{.sh,run}: use simpler .rel() instead of `. "$(dirname "${BASH_SOURCE<sup>0</sup>}")"/...` for relative includes

bugfix: lib/runscripts/util.run: need to include sh/make.sh for all runscripts that use make-style commands

lib/sh/util.sh: run_args_cmd(): moved test of $? to lib/runscripts/util.run on_exit() since it needs to be performed for all run_args_cmd() functions, not just the default implementation. (this test ensures that no commands are executed if the EXIT trap was encountered due to a parsing/loading error).

lib/runscripts/util.run: added setting of $top_file, $top_filename to set_paths()

lib/runscripts/util.run: set $top_file, $top_filename in a function (set_paths__util_run())

lib/runscripts/util.run: $top_file: also match dir-level runscripts by removing /run suffix

*{.sh,run}: echo all global vars (except those defined before echo_vars is available)

*{.sh,run}: removed extra space between function name and (), which is apparently not needed even though `help function` includes it. this greatly improves readability, including when function names are pasted into commit messages!

moved lib/*.sh to sh/ subdir so it's easier to find the .sh files among all the other lib/ files

lib/util.sh: run all commands verbosely by default, not just runscripts. this ensures verbose output for invoked commands like inputs/GBIF/MySQL_export.

lib/util.sh: moved $top_file* to runscripts/util.run because they only apply to runscripts

lib/runscripts/util.run: tell users to override run_args_cmd rather than this function to perform other commands, so that on_exit () can contain other exit-related processing that should not be overriden by the user

lib/util.sh: echo_vars (): output vars with log_level 3 so they can be excluded separately from function calls to reduce clutter in the logging output. increase the default util.run verbosity so that vars are still printed by default.

*{.sh,run}: changed echo_func to an alias that includes the "$", so that callers don't need to specify the "$" manually. although the original echo_func function is still there, callers need to switch over to the alias at the same time as it's defined because otherwise the "$@" would be doubled, since echo_func refers to the alias instead.

moved lib/*.run into runscripts/ subdir so runscripts are grouped together and easier to find rather than being scattered throughout lib/

lib/util.run: doc comment: changed "run scripts" to "runscripts"

lib/util.run: factored general utils (non-runscript-specific) out into new util.sh

lib/util.run: renamed $verbose to $verbosity because it's an integer level, not a boolean. continue to support specifying the verbosity in $verbose.

lib/util.run: support $verbose="", which is treated as 0

lib/util.run: only automatically echo env vars when they are set if verbosity is >= 2

lib/util.run: added $verbose var to control logging. this is normally set to 0, but defaults to 2 for a runscript.

lib/util.run: moved `shopt -s expand_aliases` inside the include guard so callers can override the setting without it being reset if util.run is included again

bugfix: lib/util.run: added include guard to prevent issues in "diamond includes", where a runscript includes two runscripts and each includes util.run, causing the second include of util.run to reset any methods overridden in the first included runscript. this prevents util.run from being included twice in the first place.

lib/util.run: added include_guard_var (), self_not_included () for use by path-based include guards

lib/util.run: echo_stdin (): print a separator before and after the echoed output to help distinguish it from other verbose output

lib/util.run: echo_export (): run the export builtin using `builtin` to avoid recursively calling any export alias or function defined by the user (e.g. `alias export=echo_export`. this causes util.run to be idempotent, such that it can be included multiple times without causing problems due to the redefinition of functions, vars, etc.

lib/util.run: added set_var ()

bugfix: lib/util.run: run_args_cmd (): `set --`: need to use eval so that the output of reverse is interpreted as escaped args rather than split using $IFS

bugfix: lib/util.run: run_args_cmd (): BASH_ARGV is stored in reverse order, so it needs to be reversed to be usable as $@

lib/util.run: added reverse ()

lib/util.run: added zip/unzip_newer aliases

lib/util.run: added zip/unzip echo_run aliases

bugfix: lib/util.run: inline_make (): put echo_func at the top of the function

lib/util.run: inline_make (): pass Makefile commands using /dev/fd/3 (i.e. 3<<'EOF' ...) instead of stdin, to allow stdin to be used by commands that prompt the user

lib/util.run: inline_make (): use <() to pass Makefile commands as a named descriptor rather than using stdin, to allow stdin to be used by commands that prompt the user

bugfix: lib/util.run: echo_vars (): remove any value to set (=*) from the vars, since this is often used with export

bugfix: lib/util.run: echo_export (): set the vars before echoing them

lib/util.run: run_args_cmd (): use new canon_rel_path() to resolve .. in the script path, so it's easier to see where the script is actually located

lib/util.run: echo_func (): use new canon_rel_path() to resolve .. in the script path, so it's easier to see where the script is actually located

lib/util.run: added canon_rel_path ()

lib/util.run: inline_make (): provide $self as make var

lib/util.run: inline_make (): provide self_dir to make as env var instead of as make var, to avoid specifying every make var both as a local var and as a make var in the make command

lib/util.run: export alias: added comment explaining what it does

lib/util.run: aliased export to echo_export so all env vars are automatically echoed when they are set

lib/util.run: added echo_vars (), echo_export ()

lib/util.run: inline_make (): added local $self and use it to create $self_dir

lib/util.run: inline_make (): set $self_dir as a local var before passing it to make, to avoid clutter in the command that invokes make

lib/util.run: run_cmd (): renamed to run_args_cmd to clarify that this runs only the command line args command, not any command. added doc comment to clarify this.

lib/util.run: EXIT trap: use on_exit() function which calls run_cmd instead of having run_cmd be the handler, so that users can override this function to perform other commands (or no commands) after the script is read

lib/util.run: echo_func (): use the caller's FUNCNAME via the $FUNCNAME[] array instead of requiring them to pass it in the function args as `echo_func "$FUNCNAME" "$@"`

lib/util.run: echo_func: Fixed bug where need to use BASH_LINENO⁰ for the line #s to match up with the files. For some reason the required array indexes for BASH_SOURCE (1) and BASH_LINENO (0) differ by one.

lib/util.run: echo_func: Include the line # of the function to make it easier to find where the code being run is

lib/util.run: run_cmd: If bash exited with an error, don't run the "$@" command. This test is necessary because `trap run_cmd EXIT` will run run_cmd as the result of any exit from the shell, including an error.

*run: Use -e option to bash on the #! line instead of separate `set -o errexit` line so that there is no issue with the `set -o errexit` line getting separated from the #! line (errexit is required for the scripts to work properly)

lib/util.run: run_cmd: When no command specified, default to running the `all` command, just like make

lib/util.run: Run run_cmd at shell exit (using trap) instead of requiring every runscript to have `run_cmd ` at the end of it

lib/util.run: fwd: Check that $subdirs is defined. Added $subdirs to usage.

lib/util.run: fwd: Added usage

lib/util.run: run_cmd: Echo the command being run, including the top-level run script. This is in addition to the echoing of the command in the function itself (using echo_func), which provides both the runscript that was run and the file where the invoked command was actually located (which may be different due to includes).

lib/util.run: Echo the command at the beginning of each function using new echo_func, instead of having to type echo_run before every call to a function. Note that because echo_func uses BASH_SOURCE, the path to the file containing the function will be included in the debug message, which greatly facilitates locating which file a command is in.

lib/util.run: Added echo_func

lib/util.run: Added echo_cmd and use it in echo_run

lib/util.run: echo_cmd(): Renamed to echo_run for clarity, because it also runs the command

lib/util.run: Added inline_make()

lib/util.run: Added echo_stdin()

Added lib/util.run with general functions and template for run scripts (a bash-based replacement for make). Unlike make, run scripts support full bash functionality including multiline commands. The run script template also includes syntax for various kinds of relative includes in bash.
