@ -12,132 +12,87 @@ Public: Template parser function. Writes templates to stdout.
|
||||
* $0 - Name of the mo file, used for getting the help message.
|
||||
* $@ - Filenames to parse.
|
||||
|
||||
Options:
|
||||
Returns nothing.
|
||||
|
||||
--allow-function-arguments
|
||||
|
||||
Permit functions in templates to be called with additional arguments. This puts template data directly in to the path of an eval statement. Use with caution. Not listed in the help because it only makes sense when mo is sourced.
|
||||
`mo::debug()`
|
||||
-------------
|
||||
|
||||
-u, --fail-not-set
|
||||
Internal: Show a debug message
|
||||
|
||||
Fail upon expansion of an unset variable. Default behavior is to silently ignore and expand into empty string.
|
||||
|
||||
-x, --fail-on-function
|
||||
|
||||
Fail when a function used by a template returns an error status code. Alternately, ou may set the MO_FAIL_ON_FUNCTION environment variable to a non-empty value to enable this behavior.
|
||||
|
||||
-e, --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.
|
||||
|
||||
-h, --help
|
||||
|
||||
Display a help message.
|
||||
|
||||
-s=FILE, --source=FILE
|
||||
|
||||
Source a file into the environment before processing template files. This can be used multiple times.
|
||||
|
||||
--
|
||||
|
||||
Used to indicate the end of options. You may optionally use this when filenames may start with two 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. This puts the content from the template directly into an eval statement. Use with extreme care.
|
||||
* MO_FUNCTION_ARGS - Arguments passed to the function
|
||||
* 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_ORIGINAL_COMMAND - Used to find the `mo` program in order to generate a help message.
|
||||
* $1 - The debug message to show
|
||||
|
||||
Returns nothing.

-------------
|
||||
|
||||
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.

||||
* $3 - Tag content
|
||||
* $4 - Content after the tag

`moStandaloneAllowed()`
|
||||
-----------------------
|
||||
|

|
||||
|
||||
* $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".

### 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.
|
||||
|
||||
* `MO_ALLOW_FUNCTION_ARGUMENTS` - When set to a non-empty value, this allows functions referenced in templates to receive additional options and arguments. This puts the content from the template directly into an eval statement. Use with extreme care.
|
||||
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_VERSION` - Version of `mo`.
|
||||
* `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.

### Porting and Backporting
|
||||
|
||||
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.
|
||||
In case of problems, setting MO_DEBUG to a non-empty value will give you LOTS of output.
|
||||
|
||||
MO_DEBUG=1 ./mo my-template
|
||||
|
||||
|
||||
### Failed Specs
|
||||
|
||||
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.
|
||||
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.
|
||||
|
||||
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.
|
||||
* 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.
|
||||
* 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"
