vim/nvim autocommands don't work quite right. Each opened file has to be saved first at least once for the next autocommand to work.
So, say, if you have three files open, and you want to save the third one, you have to run :w on the first and the second one at least once in order for the third autocommand to start responding.
So far, I was unable to figure out what the problem is. I opened an issue that shows the Vim script that gets generated, so if anyone has any suggestions, I'd be glad to hear from you.
ezedl requires that lua (v5.4) be installed.
On Debian, run sudo apt install lua5.4 to install it.
lua 5.4 is the version of lua that ezedl was tested with. ezedl first checks PATH for a binary called lua5.4, and if that is not available, it uses lua as a fallback binary name.
To use ezedl's -e, --edit mode, a text editor is needed.
Vim (vim) or Neovim (nvim) are strongly recommended since ezedl offers functionality that is unique to working with those text editors, and that greatly facilitates the process of editing, compiling and previewing ezEDL files.
On Debian, run sudo apt install vim-gtk3 to install Vim. (The gtk3 version of the package is recommended since it provides system clipboard integration out of the box.)
To install Neovim on Debian, run sudo apt install neovim.
ezedl was written and tested on Debian 12, and takes advantage of standard utilities that come with the system. In order to run ezedl on other systems, make sure that the following are installed and available on system's PATH:
- Bash >= 5.2.15
- Enhanced getopt
- GNU coreutils
- GNU sed
-
Clone this repository to a directory of your choice (e.g.
~/repos):cd ~/repos git clone https://github.com/linguisticmind/ezedl.git
-
Symlink or copy the script file to a directory on your
PATH(e.g.~/bin):cd ~/bin # To symlink: ln -sv ../repos/ezedl/ezedl # To copy: cp -av ../repos/ezedl/ezedl .
Symlinking is recommended, otherwise you will have to do an additional step (see step 3).
-
If you copied the script file in step 2 instead of symlinking it, you will also need to copy the
libdirectory to a location of your choice (e.g.~/lib), and set theEZEDL_LIB_DIRenvironment variable:cd ~/lib cp -av ../repos/ezedl/lib ezedl
Now, add the following line to your
~/.bashrcfile (or other appropriate configuration file for your shell):export EZEDL_LIB_DIR="$HOME"'/lib/ezedl'
Restart your terminal session for changes to take effect.
You can also test the environment variable in your terminal session before adding it to the shell configuration file, like this:
EZEDL_LIB_DIR="$HOME"'/lib/ezedl' ezedl <arguments to ezedl>
-
(OPTIONAL) Symlink or copy the man page to a directory on your
MANPATH(e.g.~/man):cd ~/man/man1 # The `man` directory should contain subdirectories for different manual sections: `man1`, `man2` etc. # To symlink: ln -sv ../../repos/ezedl/man/man1/ezedl.1 # To copy: cp -av ../../repos/ezedl/man/man1/ezedl.1 .
A copy of the manual page is also included in this README file.
-
(OPTIONAL) Copy the example config file to the config directory:
mkdir -v ~/.config/ezedl cp -v ~/repos/ezedl/config.bash ~/.config/ezedl

NAME
ezedl - an mpv EDL preprocessor
SYNOPSIS
ezedl [<options>] [<file>]
ezedl -e|--edit [<options>] [<file> ...]
DESCRIPTION
ezedl allows the user to create and edit mpv EDL files with ease. It
greatly simplifies and makes more convenient the process of working
with mpv EDL files in a plain text editor.
ezedl uses an INI-like syntax to create mpv EDL elements such as seg‐
ments and headers. Vim and Neovim integration is provided out of the
box, allowing for easy editing, and on-the-fly compiling and previewing
of mpv EDL files.
The official mpv EDL format documentation can be found here:
<https://github.com/mpv-player/mpv/blob/master/DOCS/edl-mpv.rst>.
ezedl requires lua (v5.4) to be installed and available on system's
PATH.
To use ezedl's -e, --edit mode, a text editor is needed. Vim (vim) or
Neovim (nvim) are strongly recommended since ezedl offers functionality
that is unique to working with those text editors, and that greatly fa‐
cilitates the process of editing, compiling and previewing ezEDL files.
OPTIONS
Passing arguments to options
Enhanced getopt syntax applies when passing options. There is one im‐
portant point to highlight when it comes to passing options with re‐
quired vs optional arguments.
In case of a short option, if an option takes a *required* argument,
the argument may be written as a separate parameter, *or* directly af‐
ter the option character. If an option takes an *optional* argument,
however, the argument *must* be written directly after the option char‐
acter.
In case of a long option, if an option takes a *required* argument, the
argument may be written as a separate parameter, *or* directly after
the option name, separated by an equals sign (`=`). If an option takes
an *optional* argument, however, the argument *must* be writtent di‐
rectly after the option name, separated by an equals sign (`=`).
Short option Long option
Required argument -o <value> --option <value>
-o<value> --option=<value>
Optional argument -o[<value>] --option[=<value>]
Options that take optional arguments can be recognized in the options
list below by their <value> and the preceding equals sign being en‐
closed in square brackets:
-o, --option[=<value>]
Per-file options
Options that can be set on per-file basis are marked as such:
-o, --option (per-file)
These options can be set multiple times, each subsequent instance set‐
ting the value for the next <file> - and all the <file>s that may fol‐
low it if this is the last instance of setting that option.
For example:
ezedl --per-file-option=1 --per-file-option=2 file1.ext file2.ext file3.ext
This sets --per-file-option to `1` for `file1.ext`, and to `2` for
`file2.ext` and `file3.ext`.
Edit mode
-e, --edit
Enable edit mode.
-E, --no-edit
Disable edit mode. This is the default.
-k, --edit-keep-temporary (per-file)
Keep temporary files.
-K, --edit-no-keep-temporary (per-file)
Do not keep temporary files. This is the default.
The temporary files are deleted right after the editor closes.
-f, --edit-save-file[={<path>[/]|<path>/<name>.[ez]edl|<name>.[ez]edl}]
(per-file)
Save compiled files instead of creating temporary files. The de‐
fault value is unset. When omitted, the value is ``.
If <path> is not given, the EDL files are saved to the current
working directory. If <name> is not given, the name of the
source file with an appropriate change to the filename extension
will be used.
A `.edl` or `.ezedl` extension after <name> is required because
it serves to distinguish a directory called "<name>" from a name
of an mpv EDL or an ezEDL file. To save to a directory whose
name ends in `.edl` or `.ezedl` (without specifying
<name>.[ez]edl), add a trailing forward slash (`/`) after
<path>.
-F, --edit-no-save-file (per-file)
Do not save compiled files, but generate temporary files in‐
stead. This is the default.
-d, --edit-save-mkdir (per-file)
Create the save directory (the <path> value of --edit-save-file)
if it does not exist.
-D, --edit-save-no-mkdir (per-file)
Do not create the save directory (the <path> value of --edit-
save-files-* options) if it does not exist. This is the default.
-y, --edit-save-overwrite (per-file)
Allow overwriting existing files when saving files.
-Y, --edit-save-no-overwrite (per-file)
Do not allow overwriting existing files when saving files. This
is the default.
-o, --edit-open-if-exists (per-file)
Skip compiling and open the target file in the editor if that
file already exists.
If this option is set, -y, --edit-save-overwrite / -Y, --edit-
save-no-overwrite has no effect.
-O, --edit-no-open-if-exists (per-file)
Do not skip compiling if the target file already exists. This is
the default.
Further behavior dependes on the value of -y, --edit-save-over‐
write / -Y, --edit-save-no-overwrite.
-V, --editor=<value>
Choose an editor to use in -e, --edit mode.
<value> can be one of the following:
auto (default)
Automatically choose an editor based on the values of the
VISUAL and EDITOR environment variables.
If one of said variables is set to a supported text edi‐
tor (`vim` or `nvim`), then that editor will be used.
Otherwise, the `editor_custom` function will be used.
See `custom` below, and ENVIRONMENT for more information.
vim Use Vim as the text editor.
nvim Use Neovim as the text editor.
custom Use the `editor_custom` function to launch a custom text
editor.
The `editor_custom` function can be defined in the con‐
figuration file. The default `editor_custom` function is
`function editor_custom { nano "${dest_files[@]}"; }`.
-v, --vim-layout=<value>
Choose an layout to use when using vim as an editor.
<value> can be one of the following:
simple Each generated file is opened in a separate tab.
split (default)
Tabs are split into two panes, with the generated file at
the top, and the original file at the bottom.
tab Each generated and original file is opened in a separate
tab.
-h, --vim-split-height=<value>
Adjust the height of the bottom pane when using the `split`
value of -v, --vim-layout. <value> can be a positive integer or
an empty string. The default <value> is one-third of the avail‐
able screen height if the Bash variable LINES is set, otherwise
the default value is an empty string.
Compiling
-t, --convert-timestamps (per-file)
Convert timestamps from seconds to HH:MM:SS.s format. This is
the default.
This option only has effect when compiling from mpv EDL to
ezEDL.
-T, --no-convert-timestamps (per-file)
Do not convert timestamps from seconds to HH:MM:SS.s format.
This option only has effect when compiling from mpv EDL to
ezEDL.
-a, --convert-length-to-end (per-file)
Use `end` instead of `length` as an alternative way to indicate
the end of the segment. This is the default.
This option only has effect when compiling from mpv EDL to
ezEDL.
-A, --no-convert-length-to-end (per-file)
Do not use `end` as an alternative way to indicate the end of
the segment. Use mpv EDL's original `length`.
This option only has effect when compiling from mpv EDL to
ezEDL.
-b, --include-empty-lines (per-file)
Preserve blank lines. This is the default.
-B, --no-include-empty-lines (per-file)
Do not preserve blank lines.
-c, --include-comments (per-file)
Preserve comments. This is the default.
-C, --no-include-comments (per-file)
Do not preserve comments.
Direction policy
--direction={auto|to|from} (per-file)
Set direction of compiling. The default value is `auto`.
`to` refers to compiling *to* ezEDL (mpv EDL -> ezEDL); `from`,
to compiling *from* ezEDL (ezEDL -> mpv EDL).
NB: Provided that the files passed to ezedl have appropriate
filename extensions and headers, there is no need to manually
set --direction.
Extension Header
ezEDL .ezedl # ezEDL v0
mpv EDL .edl # mpv EDL v0
In cases where filename extensions and/or headers are missing,
or conflict with each other, the behavior is determined by the
values set by the rest of the --direction-* options listed be‐
low.
--direction-auto-extension-no-header={warning|error|quiet} (per-file)
What to do when --direction is `auto`, and a file has an exten‐
sion, but is missing a matching header. The default value is
`error`.
--direction-auto-header-no-extension={warning|error|quiet} (per-file)
What to do when --direction is `auto`, and a file has a header,
but is missing a matching extension. The default value is `warn‐
ing`.
--direction-auto-fallback={to|from} (per-file)
Fallback compiling direction for cases when autodetection of
compiling direction fails. The default value is `to`.
See --direction-auto-no-header-no-extension for more informa‐
tion.
--direction-auto-no-header-no-extension={warning[,{to|from}]|er‐
ror|quiet[,{to|from}]} (per-file)
What to do when --direction is `auto`, and a file has neither a
recognized header, nor a recognized extension. The default value
is `error`.
Since both the extension and the header are missing, ezedl has
no way to automatically determine --direction, and thus the au‐
todetection of compiling direction fails.
When this option is set to `warning` or `quiet`, the secondary
comma-delimited value can be passed (e.g. `warning,from`) that
determines the fallback compiling direction. If this secondary
value is not given, the value set by --direction-auto-fallback
is used.
--direction-manual-extension-no-header={warning|error|quiet} (per-file)
What to do when --direction is `to` or `from`, and a file has an
extension, but is missing a matching header. The default value
is `warning`.
--direction-manual-header-no-extension={warning|error|quiet} (per-file)
What to do when --direction is `to` or `from`, and a file has a
header, but is missing a matching extension. The default value
is `warning`.
--direction-manual-no-header-no-extension={warning|error|quiet} (per-
file)
What to do when --direction is `to` or `from`, and a file has
neither a recognized header, nor a recognized extension. The de‐
fault value is `warning`.
Other
--color
Colorize the output. This is the default.
--no-color
Disable colorization of the output.
--help Print help.
--version
Print version information.
ENVIRONMENT
EZEDL_LIB_DIR
ezedl is a program that consists of multiple files. All the files that
ezedl requires are stored in the lib directory located in the same
folder as the main script.
Normally, ezedl should be able to determine its own locatiion, and thus
the location of the lib folder. If for whatever reason ezedl is unable
to determine its own location, or the user wishes to store ezedl li‐
brary files elsewhere, the EZEDL_LIB_DIR enviroment variable can be set
to manually point to a directory containing ezedl library files.
VISUAL / EDITOR
The values of VISUAL and EDITOR environment variables are respected
when choosing the editor to use in -e, --edit mode if -V, --editor is
set to `auto`.
VISUAL is evaluated first. If not set, then EDITOR is evaluated. See
-V, --editor for more information.
FILES
A configuration file can be used to set default options.
The configuration file's location is $XDG_CONFIG_HOME/ezedl/con‐
fig.bash. If XDG_CONFIG_HOME is not set, it defaults to ~/.config.
