* templates: add map functionsRobin Jarry2023-06-101-0/+30
| | | | | | | | | Similar to switch and .StyleSwitch, add map and .StyleMap to work on lists. An extra "exclude" item is available to filter elements out of the list. Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Inwit <inwit@sindominio.net>
* commands: expand and complete template codeKoni Marti2023-05-161-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | Expand and complete template code. The exline does understand template code and can evaluate it. With this patch, the completion systems supports writing the templates by showing the available template data fields and template functions. Pressing <Tab> after }} will show the evaluated template in the completion menu. Complex template code, such as if-else statements work as well. Examples: :filter -f {{<Tab> will show the possible template data fields and functions :filter -f {{index (.To|email) 0}}<Tab> will show the value of the template expression in the completion list Pressing <Tab> twice after a completed template expression will substitute the expression with its value. :{{if match .Folder "INBOX"}}check-mail{{else}}cf INBOX{{end}} Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

* templates: add match functionRobin Jarry2023-03-081-0/+2
| | | | | | | | | | | | | | Add a match function that returns true if a string matches the provided regular expression. The compiled regular expressions are cached in a sync.Map to avoid repetitive compilations of the same expressions. Caveat: if the user mixes the arguments order, it may cause the cache to consume a lot of memory filled with garbage regular expression objects. Ideally, we would need to limit the size of this cache and/or use a LRU cache implementation. Maybe someday?

* templates: unify data interfaceRobin Jarry2023-02-203-420/+18
| | | | | | | | | | | | | | | | | | | | | | | Require that all aerc template data objects implement the same TemplateData interface. Implement that interface in two different places: 1) state.TemplateData (renamed/moved from templates.TemplateData). This structure (along with all its methods) needs to be decoupled from the templates package to break the import cycle with the config package. This allows much simpler construction of this object and ensure that values are calculated only when requested. 2) config.dummyData (extracted from templates). This is only used in the config package to validate user templates. Putting it here allows also to break an import cycle. Use state.TemplateData everywhere (including for account tabs title rendering). Signed-off-by: Robin Jarry <robin@jarry.cc> Reviewed-by: Moritz Poldrack <moritz@poldrack.dev>
* templates: add initials functionBence Ferdinandy2023-02-121-0/+15
| | | | | | | | | | When listing all addresses with names, in for example the To field, one might end up with a very long string. Add the initials function, which extracts the names from addresses and then shortens each of them to the initials of the name.

* config: add columns based index formatRobin Jarry2023-01-061-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The index-format option comes from mutt and is neither user friendly, nor intuitive. Introduce a new way of configuring the message list contents. Replace index-format with multiple settings to make everything more intuitive. Reuse the table widget added in the previous commit. index-columns Comma-separated list of column names followed by optional alignment and width specifiers. column-separator String separator between columns. column-$name One setting for every name defined in index-columns. This supports golang text/template syntax and allows access to the same message information than before and much more. When index-format is still defined in aerc.conf (which will most likely happen when users will update after this patch), convert it to the new index-columns + column-$name and column-separator system and a warning is displayed on startup so that users are aware that they need to update their config.

* config: do not hardcode sharedirRobin Jarry2022-02-191-0/+8
| | | | | | | | | | | | Instead of using a static SHAREDIR at compile time, use a list of standard paths to use at runtime for templates, config files and stylesets.

* compose: use a proper header instead of a string mapReto Brunner2020-11-141-33/+49
| | | | | | | | | | | | | Prior to this commit, the composer was based on a map[string]string. While this approach was very versatile, it lead to a constant encoding / decoding of addresses and other headers. This commit switches to a different model, where the composer is based on a header. Commands which want to interact with it can simply set some defaults they would like to have. Users can overwrite them however they like. In order to get access to the functions generating / getting the msgid go-message was upgraded.

* Remove ability to specify headers in the editorReto Brunner2020-04-241-4/+5

* toLocal template functionsqwishy2020-02-251-0/+5
| | | | | | | | | | Hi. This adds a template function to convert a time to the local time zone. And modifies the default quoted_reply template to use it and show the time zone when formatting the timestamp of the quoted message. Previously, the quoted message timestamp was UTC and it would format it without the time zone. And I thought it might be a little confusing or weird to some normal people when I email them and I don't want normal people to be confused or think that I'm weird.
