`mo()`
------
mo()
----
Public: Template parser function. Writes templates to stdout.
* $0 - Name of the mo file, used for getting the help message.
* --fail-not-set - Fail upon expansion of an unset variable. Default behavior is to silently ignore and expand into empty string.
* --false - Treat "false" as an empty value. You may set the MO_FALSE_IS_EMPTY environment variable instead to a non-empty value to enable this behavior.
* --help - Display a help message.
* --source=FILE - Source a file into the environment before processint template files.
* -- - Used to indicate the end of options. You may optionally use this when filenames may start with two hyphens.
* $@ - Filenames to parse.
Returns nothing.
Mo uses the following environment variables:
`mo::debug()`
-------------
Internal: Show a debug message
* $1 - The debug message to show
* MO_FAIL_ON_UNSET - When set to a non-empty value, expansion of an unset env variable will be aborted with an error.
* MO_FALSE_IS_EMPTY - When set to a non-empty value, the string "false" will be treated as an empty value for the purposes of conditionals.
* MO_ORIGINAL_COMMAND - Used to find the `mo` program in order to generate a help message.
Returns nothing.
`mo::debugShowState()`
----------------------
files
-----
Internal: Show a debug message and internal state information
No arguments
Returns nothing.
After we encounter two hyphens together, all the rest of the arguments are files.
`mo::error()`
-------------
MO_FAIL_ON_UNSET
----------------
Internal: Show an error message and exit

Set a flag indicating we've encountered double hyphens
* $1 - Filename that has the help message
files
-----
Every arg that is not a flag or a option should be a file
moFindEndTag()
--------------
Internal: Scan content until the right end tag is found. Creates an array with the following members:

Returns nothing.
`mo::evaluateListOfSingles()`
-----------------------------
Internal: Convert an argument list to individual values.
* $1 - Destination variable name
* $2-@ - A list of argument types and argument name/value.
This assumes each value is separate from the rest. In contrast, mo::evaluate will pass all arguments to a function if the first value is a function.

Internal: Process a chunk of content some number of times. Writes output to stdout.
No arguments.
Returns 0 if this is a standalone tag, 1 otherwise.

* $2 - Current name (the variable NAME for what {{.}} means)
* $3 - true when no content before this, false otherwise
Returns nothing.
`mo::escape()`
moPartial()
-----------
Internal: Process a partial.
Indentation should be applied to the entire partial.
This sends back the "is beginning" flag because the newline after a standalone partial is consumed. That newline is very important in the middle of content. We send back this flag to reset the processing loop's `moIsBeginning` variable, so the software thinks we are back at the beginning of a file and standalone processing continues to work.
Prefix all variables.
* $1 - Name of destination variable. Element [0] is the content, [1] is the true/false flag indicating if we are at the beginning of content.
* $2 - Content before the tag that was not yet written

Returns nothing.
moSplit()
---------
Internal: Split a larger string into an array.
* $1 - Destination variable
* $2 - String to split
* $3 - Starting delimiter
* $4 - Ending delimiter (optional)
Returns nothing.
moStandaloneAllowed()
---------------------
Internal: Handle the content for a standalone tag. This means removing whitespace (not newlines) before a tag and whitespace and a newline after a tag. That is, assuming, that the line is otherwise empty.
* $1 - Name of destination "content" variable.
* $2 - Content before the tag that was not yet written
* $3 - Tag content (not used)
* $4 - Content after the tag
* $5 - true/false: is this the beginning of the content?
Returns nothing.
moStandaloneDenied()
--------------------
Internal: Handle the content for a tag that is never "standalone". No adjustments are made for newlines and whitespace.
* $1 - Name of destination "content" variable.
* $2 - Content before the tag that was not yet written
* $3 - Tag content (not used)
* $4 - Content after the tag
Returns nothing.
moTest()
--------
Internal: Determines if the named thing is a function or if it is a non-empty environment variable. When MO_FALSE_IS_EMPTY is set to a non-empty value, then "false" is also treated is an empty value.
Do not use variables without prefixes here if possible as this needs to check if any name exists in the environment
* $1 - Name of environment variable or function
* $2 - Current value (our context)
* MO_FALSE_IS_EMPTY - When set to a non-empty value, this will say the string value "false" is empty.
Returns 0 if the name is not empty, 1 otherwise. When MO_FALSE_IS_EMPTY is set, this returns 1 if the name is "false".
moTestVarSet()

* $1 - Destination variable name
* $2 - Value to escape

----------------------------
moTrimChars()
-------------
Internal: Get the content up to the end of the block by minimally parsing and balancing blocks. Returns the content before the end tag to the caller and removes the content + the end tag from MO_UNPARSED. This can change the delimiters, adjusting MO_OPEN_DELIMITER and MO_CLOSE_DELIMITER.
Internal: Trim the leading whitespace only.
* $1 - Destination variable name
* $2 - Token string to match for a closing tag
* $1 - Name of destination variable
* $2 - The string

* $1 - Destination variable for the array of contents.
* $2 - Stop processing when this content is found.
The list of tokens are in RPN form. The first item in the resulting array is the number of actual tokens (after combining command tokens) in the list.
Given: a 'bc' "de\"\n" (f {g 'h'}) Result: ([0]=4 [1]=NAME [2]=a [3]=VALUE [4]=bc [5]=VALUE [6]=$'de\"\n' [7]=NAME [8]=f [9]=NAME [10]=g [11]=VALUE [12]=h [13]=BRACE [14]=2 [15]=PAREN [16]=2

There are additional features that the program supports. Try using `mo --help` to see what is available.
Please note that this command is written in Bash and pulls data from either the environment or (when using `--source`) from a text file that will be sourced and loaded into the environment, which means you will need to have Bash-style variables defined. Please see the examples in `demo/` for different ways you can use `mo`.
Enhancements
------------
In addition to many of the features built-in to Mustache, `mo` includes a number of unique features that make it a bit more powerful.
### Loop @key
`mo` implements Handlebar's `@key` references for outputting the key inside of a loop:
Env:
```bash
myarr=( foo bar )
# Bash v4+
declare -A myassoc
myassoc[hello]="mo"
myassoc[world]="is great"
```
Template:
```handlebars
{{#myarr}}
- {{@key}} {{.}}
{{/myarr}}
{{#myassoc}}
* {{@key}} {{.}}
{{/myassoc}}
```
Output:
```markdown
- 0 foo
- 1 bar
* hello mo
* world is great
```
### Helpers / Function Arguments
Function Arguments are not a part of the official Mustache implementation, and are more often associated with Handlebar's Helper functionality.
`mo` allows for passing strings to functions.
```handlebars
{{myfunc foo bar}}
```
For security reasons, these arguments are not immediately available to function calls without a flag.
#### with `--allow-function-arguments`
```bash
myfunc() {
# Outputs "foo, bar"
echo "$1, $2";
}
```
#### Using `$MO_FUNCTION_ARGS`
```bash
myfunc() {
# Outputs "foo, bar"
echo "${MO_FUNCTION_ARGS[0]}, ${MO_FUNCTION_ARGS[1]}";
}
```
### Triple Mustache, Parenthesis, and Quotes
Normally, triple mustache syntax, such as `{{{var}}}` will avoid HTML escaping of the variable. Because HTML escaping is not supported in `mo`, this is now used differently. Anything within braces will be looked up and the values will be concatenated together and the result will be treated as a value. Anything in parenthesis will be looked up, concatenated, and treated as a name. Also, anything in single quotes is passed as a value; double quoted things first are unescaped and then passed as a value.
```
# Example input
var=abc
user=admin
admin=Administrator
u=user
abc=([0]=zero [1]=one [2]=two)
```
| Mustache syntax | Resulting output | Notes |
|-----------------|------------------|-------|
| `{{var}}` | `abc` | Normal behavior |
| `{{var us}}` | `abcus` | Concatenation |
| `{{'var'}}` | `var` | Passing as a value |
| `{{"a\tb"}}` | `a b` | There was an escaped tab in the value |
| `{{u}}` | `user` | Normal behavior |
| `{{{u}}}` | `user` | Look up "$u", treat as the value `{{'user'}}` |
| `{{(u)}}` | `admin` | Look up "$u", treat as the name `{{user}}` |
| `{{var user}}` | `abcuser` | Concatenation |
| `{{(var '.1')}}` | `one` | Look up "$var", treat as "abc", then concatenate ".1" and look up `{{abc.1}}` |
In double-quoted strings, the following escape sequences are defined.
* `\"` - Quote
* `\b` - Bell
* `\e` - Escape (note that Bash typically uses $'\E' for the same thing)
* `\f` - Form feed
* `\n` - Newline
* `\r` - Carriage return
* `\t` - Tab
* `\v` - Vertical tab
* Anything else will skip the `\` and place the next character. However, this implementation is allowed to change in the future if a different escape character mapping becomes commonplace.
Environment Variables and Functions
-----------------------------------
There are several functions and variables used to process templates. `mo` reserves variables that start with `MO_` for variables exposing data or configuration, functions starting with `mo::`, and local variables starting with `mo[A-Z]`. You are welcome to use internal functions, though only ones that are marked as "Public" should not change their interface. Scripts may also read any of the variables.
Functions are all executed in a subshell, with another subshell for lambdas. Thus, your lambda can't affect the parsing of a template. There's more information about lambdas when talking about tests that fail.
* `MO_ALLOW_FUNCTION_ARGUMENTS` - When set to a non-empty value, this allows functions referenced in templates to receive additional options and arguments.
* `MO_CLOSE_DELIMITER` - The string used when closing a tag. Defaults to "}}". Used internally.
* `MO_CLOSE_DELIMITER_DEFAULT` - The default value of `MO_CLOSE_DELIMITER`. Used when resetting the close delimiter, such as when parsing a partial.
* `MO_CURRENT` - Variable name to use for ".".
* `MO_DEBUG` - When set to a non-empty value, additional debug information is written to stderr.
* `MO_FUNCTION_ARGS` - Arguments passed to the function.
* `MO_FAIL_ON_FILE` - If a filename from the command-line is missing or a partial does not exist, abort with an error.
* `MO_FAIL_ON_FUNCTION` - If a function returns a non-zero status code, abort with an error.
* `MO_FAIL_ON_UNSET` - When set to a non-empty value, expansion of an unset env variable will be aborted with an error.
* `MO_FALSE_IS_EMPTY` - When set to a non-empty value, the string "false" will be treated as an empty value for the purposes of conditionals.
* `MO_OPEN_DELIMITER` - The string used when opening a tag. Defaults to "{{". Used internally.
* `MO_OPEN_DELIMITER_DEFAULT` - The default value of MO_OPEN_DELIMITER. Used when resetting the open delimiter, such as when parsing a partial.
* `MO_ORIGINAL_COMMAND` - Used to find the `mo` program in order to generate a help message.
* `MO_PARSED` - Content that has made it through the template engine.
* `MO_STANDALONE_CONTENT` - The unparsed content that preceeded the current tag. When a standalone tag is encountered, this is checked to see if it only contains whitespace. If this and the whitespace condition after a tag is met, then this will be reset to $'\n'.
* `MO_UNPARSED` - Template content yet to make it through the parser.

### Mustache Syntax
* Dotted names are supported but only for associative arrays (Bash 4). See [`demo/associative-arrays`](demo/associative-arrays) for an example.
* There's no "top level" object, so `echo '{{.}}' | ./mo` does not do anything useful. In other languages you can say the data for the template is a string and in `mo` the data is always the environment. Luckily this type of usage is rare and `{{.}}` works great when iterating over an array.
* [Parents](https://mustache.github.io/mustache.5.html#Parents), where a template can override chunks of a partial, are not supported.
* There's no "top level" object, so `echo '{.}' | ./mo` does not do anything useful. In other languages you can say the data for the template is a string and in `mo` the data is always the environment. Luckily this type of usage is rare and `{.}` works great when iterating over an array.
* HTML encoding is not built into `mo`. `{{{var}}}`, `{{&var}}` and `{{var}}` all do the same thing. `echo '{{TEST}}' | TEST='<b>' mo` will give you "`<b>`" instead of "`&gt;b&lt;`".
* You can not change the delimiters.

There is a diagnostic script that is aimed to help at making sure the internal functions all work when testing the script out on a version of bash or in an environment that is causing issues. When adding new functions, please make sure this script gets updated to properly test your code.
### Failed Specs
It is acceptable for some of the official spec tests to fail. The spec runner has specific exclusions and overrides to test similar functionality that avoid the following issues.
It is acceptable for some of the official spec tests to fail. Anything dealing with multiple levels of objects (eg. `{{a.b.c}}`) and changing the delimiters (`{{= | | =}}`) will fail. Other than that, this bash implementation of the mustache spec should pass tests.
* Using `{{.}}` outside of a loop - In order to access any variable, you must use its name. In a loop, `{{.}}` will refer to the current value, but outside the loop you are unable to use this dot notation because there is no current value.
* Deeply nested data - Bash doesn't support complex data structure. Basically, just strings and arrays of strings.
* Interpolation; Multiple Calls: This fails because lambdas execute in a subshell so their output can be captured. If you want state to be preserved, you will need to write it outside of the current environment and load it again later.
Specific issues:
* Interpolation - Multiple Calls: This fails because lambdas execute in a subshell so their output can be captured. This is flagged as a TODO in the code.
* HTML Escaping - Since bash is not often executed in a web server context, it makes no sense to have the output escaped as HTML. Performing shell escaping of variables may be an option in the future if there's a demand.
* Lambdas - Function results are *not* automatically interpreted again. If you want to parse the results as Mustache content, use `mo::parse`. When they use `mo::parse`, it will use the current delimiters.
For lambdas, these examples may help.
```bash
# Retrieve content into a variable.
content=$(cat)
# Retrieve all content and do not trim newlines at the end.
content=$(cat; echo -n '.')
content=${content%.}
# Parse content using the current delimiters
mo::parse results "This is my content. Hello, {{username}}"
echo -n "$results"
# Parse content using the default delimiters
MO_OPEN_DELIMITER=$MO_OPEN_DELIMITER_DEFAULT
MO_CLOSE_DELIMITER=$MO_CLOSE_DELIMITER_DEFAULT
mo::parse results "This is my content. Hello, {{username}}"
echo -n "$results"
```

Mo is a mustache template rendering software written in bash. It inserts
environment variables into templates.
Simply put, mo will change {{VARIABLE}} into the value of that
environment variable. You can use {{#VARIABLE}}content{{/VARIABLE}} to
conditionally display content or iterate over the values of an array.
Learn more about mustache templates at https://mustache.github.io/
Simple usage:
mo [OPTIONS] filenames...
Options:
--allow-function-arguments
Permit functions to be called with additional arguments. Otherwise,
the only way to get access to the arguments is to use the
MO_FUNCTION_ARGS environment variable.
-d, --debug
Enable debug logging to stderr.
-u, --fail-not-set
Fail upon expansion of an unset variable. Will silently ignore by
default. Alternately, set MO_FAIL_ON_UNSET to a non-empty value.
-x, --fail-on-function
Fail when a function returns a non-zero status code instead of
silently ignoring it. Alternately, set MO_FAIL_ON_FUNCTION to a
non-empty value.
-f, --fail-on-file
Fail when a file (from command-line or partial) does not exist.
Alternately, set MO_FAIL_ON_FILE to a non-empty value.
-e, --false
Treat the string "false" as empty for conditionals. Alternately,
set MO_FALSE_IS_EMPTY to a non-empty value.
-h, --help
This message.
-s=FILE, --source=FILE
Load FILE into the environment before processing templates.
Can be used multiple times. The file must be a valid shell script
and should only contain variable assignments.
-o=DELIM, --open=DELIM
Set the opening delimiter. Default is "{{".
-c=DELIM, --close=DELIM
Set the closing delimiter. Default is "}}".
-- Indicate the end of options. All arguments after this will be
treated as filenames only. Use when filenames may start with
hyphens.
Mo uses the following environment variables:
MO_ALLOW_FUNCTION_ARGUMENTS - When set to a non-empty value, this allows
functions referenced in templates to receive additional options and
arguments.
MO_CLOSE_DELIMITER - The string used when closing a tag. Defaults to "}}".
Used internally.
MO_CLOSE_DELIMITER_DEFAULT - The default value of MO_CLOSE_DELIMITER. Used
when resetting the close delimiter, such as when parsing a partial.
MO_CURRENT - Variable name to use for ".".
MO_DEBUG - When set to a non-empty value, additional debug information is
written to stderr.
MO_FUNCTION_ARGS - Arguments passed to the function.
MO_FAIL_ON_FILE - If a filename from the command-line is missing or a
partial does not exist, abort with an error.
MO_FAIL_ON_FUNCTION - If a function returns a non-zero status code, abort
with an error.
MO_FAIL_ON_UNSET - When set to a non-empty value, expansion of an unset env
variable will be aborted with an error.
MO_FALSE_IS_EMPTY - When set to a non-empty value, the string "false" will
be treated as an empty value for the purposes of conditionals.
MO_OPEN_DELIMITER - The string used when opening a tag. Defaults to "{{".
Used internally.
MO_OPEN_DELIMITER_DEFAULT - The default value of MO_OPEN_DELIMITER. Used
when resetting the open delimiter, such as when parsing a partial.
MO_ORIGINAL_COMMAND - Used to find the `mo` program in order to generate a
help message.
MO_PARSED - Content that has made it through the template engine.
MO_STANDALONE_CONTENT - The unparsed content that preceeded the current tag.
When a standalone tag is encountered, this is checked to see if it only
contains whitespace. If this and the whitespace condition after a tag is
met, then this will be reset to $'\n'.
MO_UNPARSED - Template content yet to make it through the parser.
Mo is under a MIT style licence with an additional non-advertising clause.
See LICENSE.md for the full text.
This is open source! Please feel free to contribute.
