Crate string_template_plus
source ·Expand description
Introduction
This is a simple template tool that works with variable names and
HashMap
of String
. The Template
can be parsed from
str
and then you can render it using the variables in
HashMap
and any shell commands running through Exec
.
Features
- Parse the template from a
str
that’s easy to write, - Support for alternatives in case some variables are not present,
- Support for literal strings inside the alternative options,
- Support for the date time format using
chrono
, - Support for any arbitrary commands, etc.
Limitations
- You cannot use positional arguments in this template system, only named ones.
{}
will be replaced with empty string. Although you can use"0"
,"1"
, etc as variable names in the template and the render options variables. - I haven’t tested variety of names, although they should work try to keep the names identifier friendly.
- Currently doesn’t have format specifiers, for now you can use the command options with
printf
bash command to format things the way you want. Like a templatethis is $(printf "%.2f" {weight}) kg.
should be rendered with the correct float formatting.
Structs
Enums
- Parts that make up a [
Template<'a>
]. You can have literal strings, variables, time date format, command, or optional format withOPTIONAL_RENDER_CHAR
.
Statics
- Quote characters to use to make a value literal instead of a variable. In combination with
OPTIONAL_RENDER_CHAR
it can be used as a default value when variable(s) is/are not present. - Character to separate the variables. If the first variable is not present it’ll use the one behind it and so on. Keep it at the end, if you want a empty string instead of error on missing variable.
- Character that should be in the beginning of the variable to determine it as datetime format.
Traits
Functions
- Parses the template from string and makes a [
Template<'a>
]. Which you can render later./// Main Template that get’s passed around, consists of[Vec
] of [TemplatePart<'a>
]
Type Aliases
- Main Template that get’s passed around, consists of
[Vec
] of [TemplatePart<'a>
]
